Re:Intel
Humm... a site that offers absolutely no actual benchmarks just a mysterious performance number (check their FAQ) with zero ability to reproduce or verify, submitted by users with all kinds of overclocked rigs that's credible. For example it claims the FX-8350 has much better single thread performance (1,512) vs (1,217) which is not supported by any serious review I can find. So either the whole world is in a conspiracy against Passmark, or these numbers are a joke. I wonder how much AMD paid them to invent these numbers?

Re:If this was Apple...
Anyone old enough to have gone through the 32-bit to 64-bit Windows transition should know that except for some specialized applications, 64-bit doesn't really get you much additional performance. Yes it'll dramatically speed up double long int operations (2x), though I think the only place those are used are on infinite precision calculators. And it'll improve hardcore math calculations (finding primes sped up about 35%). But with byte-wise applications like data compression, there's no speedup.
Uh, I hate to break it to you, but you're armchair quarterbacking here. You think you understand the issues but you don't.
The generally expected consequence of a 64-bit transition (without knowing any deeper details) is that performance will go down. This is not about register width -- as you note for most programs that's irrelevant. It's because the growth in pointer size from 32 to 64 bits reduces effective cache size. The performance loss varies by program (i.e. software which doesn't use pointers heavily isn't really going to notice), but understanding why it's there is as simple as considering the extremely unrealistic edge case where the only data that needs to be cached is pointers. You can only fit half as many 64-bit pointers in cache. This aspect of 64-bit performance gain/loss has been observed several times in real RISC instruction sets where the other changes between 32- and 64-bit modes are minimal.
But. The other changes to the instruction set are not always minimal. You picked the most commercially important counterexample. As a side effect of its 64-bit transition, x86 went from just eight general purpose integer registers (GPRs) to sixteen. Academic research on the performance implications of architected register count suggests that 24 integer GPRs is roughly where the benefits from adding more become minimal, and that at just eight GPRs, classic 32-bit x86 was seriously register-starved. Register starvation means that compilers and humans writing assembly are forced to use a lot more register "spills". That is, it's common to run out of registers, so the programmer/compiler is frequently forced to spill one to a temporary memory location (usually the stack) and restore it later. Spill loads and stores are a significant performance drain.
With 16 GPRs, x86-64 is in a much better place. So much so that despite the negative effects of increased pointer size, most integer programs perform better on the same x86 CPU when compiled as 64-bit, even when they do not need or use the full 64-bit register width or addressing space. The gain isn't always huge, but it's usually at least good enough to avoid regression. And often it's just a plain win.
The other main advantage of 64-bit - flat memory space - isn't a pressing need for smartphones at present. So the only common smartphone apps I can see benefiting from 64-bit are maybe some games. Smartphones simply aren't the platform of choice for the heavy number-crunching applications where 64-bit processors really help.
Anybody who thinks that smartphones don't need more performance simply isn't paying attention. They're running increasingly sophisticated applications. And it's not just about number-crunching performance (though that is important). General purpose integer performance on branchy code (i.e. object-oriented GUI code) is extremely important, just as it is on the desktop.
And once again you are simply ignorant about what is going on in a specific 64-bit transition. ARM64 changed more than x86-64. Just like x86-64 they doubled the GPR count (from 16 to 32 this time). But they went further. They cleaned out old misfeatures in the ARM ISA (no more implicit bit shifts and predication for nearly every integer instruction), they entirely redesigned instruction encoding, it's basically a new thing.

Re:If this was Apple...
Samsung
... the good guys" You must be kidding. They copy and they clone. Apple does gold so Samsung does gold.Oooh! Oooh! Can I play too? LG makes a completely touchscreen interface phone, so Apple does too. Samsung offers phones with replaceable colored backs, so Apple does too. Android phones tended to have bigger screens than the iPhone, so Apple made the iPhone screen bigger. All the Android tablet makers offered a higher DPI than the original iPad, so Apple did too.
There are revolutionary changes, and there are evolutionary changes. Making evolutionary changes (like a thinner device, or a higher resolution screen, or going from 32-bit to 64-bit) is not copying. I'm not even sure offering different color phones qualifies as either revolutionary or evolutionary, but it's so damn obvious that there's no way it goes into the revolutionary category. If that's what you're relying on to base your accusations of copying, you're grasping at straws.Apple sells a 64-bit phone with a 64 bit operating system and conversion tools to take advantage of it. Samsung announces that they'll be building 64 bit phones too, one day.
Anyone old enough to have gone through the 32-bit to 64-bit Windows transition should know that except for some specialized applications, 64-bit doesn't really get you much additional performance. Yes it'll dramatically speed up double long int operations (2x), though I think the only place those are used are on infinite precision calculators.

Smartphones simply aren't the platform of choice for the heavy number-crunching applications where 64-bit processors really help.
The only reason Apple went with 64-bit so early is marketing. They have a history of discontinuing support for technologies while they still have a lot of life in them, in favor of new technologies which haven't yet been established. Sometimes this works (replacing the 5.25" floppy with 3.5" floppies, dropping floppy drives in favor of optical) and they end up leading the industry. Other times it backfires (Firewire, Lightning) and leaves them stuck with a standard different from the rest of the industry (USB). Because they dive into these new technologies head-first, they try to give their users and developers years of advance warning so they can prepare. The introduction of 64-bit processors in smartphones is clearly premature, but they're doing it as a heads up to their users and for the marketing buzz that comes with being first.
Anyway, 64-bit ARM has been available for over a year now. Just that nobody (aside from AMD) went with it prior to Apple because there was no pressing need for it. Samsung saying they'd go to 64-bit as well isn't copying Apple. It's their way of saying it's no big deal and they were scheduled to transition to it too eventually.. Consumer Reports and other customer satisfaction survey's I've seen don't rate Samsung all that highly. Apple leads the pack in every survey I've seen.
Consumer reports rates the Samsung S4 #1 well above the iPhone. Prior to that, LG was #1. The iPhone hasn't been #1 in their rankings for a couple years now.
Samsung topped Apple in the latest smartphone customer satisfaction survey. -

Re:No need to fuss
Not to argue with a know-it-all or anything, but where are your benchmarks?
Here are mine:

Windows software
I've used Passmark Performance Test before to bench Windows machines:
http://www.passmark.com/products/pt.htmVery straightforward for Windows dorks to install and use, and provides lots of simple graphs and an easy engine to make comparisons. I mostly used the demo version, but the commercial version didn't seem expensive.
Also, props to them for providing this handy reference:
http://www.videocardbenchmark.net/Again, be sure to test in as close to the final deployed configuration as possible. I've seen pretty big differences in e.g. x86_64 vs. 32-bit Windows performance, and even with different drivers installed or different BIOS settings.

burnintest. have used it for years. works fine. some systems which would run fine for days and then crash were driving us crazy. this software found memory, video and cpu problems. free version of version i bought only ran for 15 minutes. might be enough to find your problem. windows only though so that might be a problem.

Re:Clam AV
About on access scanning: this study indicates that the average time it takes to write, open, and close a file with AV software active is 180ms or so. With some software it can be far worse, up to 900ms. So yeah if you enjoy turning your 1TB hard disk into a giant 3.5" floppy bring on the AV.

How about BatteryMon:
(http://www.passmark.com/products/bat mon.htm)
"Windows program that allows the monitoring of laptop computer batteries and uninterruptible power supplies (UPS).

Re:No windows
the industry has no way to test the laptop except by loading and running an OS
Bullshit. There are burn-in diagnostic programs, and pretty much every shop I've ever seen uses them.
Selling it without an OS would require someone to write a standalone diagnostic.

Re:Anti-Phishing browser
Of course then you would see popups that look identical to the key information
This is why systems like PassMark exist. If you really need to secure the channel all the way to the user's machine to establish the marks in the first place, then you're talking about something like Palladium, aren't you?
Physical tokens like a SecurID also defeat spoofing attacks, and issuing them is pretty much routine for European banks. The US lags behind in this area, as usual. -
Benchmarks on 2 machines showed no improvementI tried Hare, Zoom, and Double Battery. Benchmarked using Performance Test and was totally... NOT blown away. There was no significant change. I also just worked as usual on my laptop/workstation and did not notice any difference, except that Windows shut down a little bit quicker with Zoom, but not much.
The programs include "benchmark" utils that tell you will get a great speedup - I can't figure out what they were testing, though!
Clearly, these people are not to be trusted. I have had better luck tweaking registry settings as someone else mentioned. If you want the benchmarks from me, let me know.

*Full* article text follows (part 2 of 3)
Choosing Chips Pt. 3
It's easy to see that assumptions may lead a consumer to believe that the INTEL product is a better processor. These basics may have some validity on paper but not so in the real world. Why the lesson on MHz, die size, bus speeds and cache? The lesson is not which processor is better. The lesson is to not make performance assumptions based in the belief that bigger numbers are better.
AMD has changed the fact that more MHz means better. As mentioned previously, side by side processor comparisons between INTEL and AMD chips prove this. The 64-dollar question is why?
By using a layman's analogy once again, an INTEL CPU engine may run at a higher RPM (MHz) but it doesn't have the equivalent torque to match the high RPM (MHz). An AMD processor may run at a lower megahertz but it does have better torque. This is an incredibly simplified explanation but it gives the needed broad brush strokes. AMD technology on how the processor is geared allows their processors to rival and, in some cases, surpass INTEL processors that are clocked at a much higher frequency.
So how does a consumer decide upon which processor? It's safe to say that the majority of PC buyers only care that it works and works fast enough for their needs. The average consumer either doesn't understand or could care less about Front Side Bus Speed, how many transistors there are, or how small a die is. A lot of PC buyers also do not realize that there is another choice beyond what is widely and visibly available on store shelves. AMD vs. INTEL marketing and product awareness is another topic altogether and best left alone lest we travel down another long road.
To berate a point, AMD has shown that in today's marketplace GHz is not the defining mark of a processor. The important piece to the education puzzle is how each of these processors compares in benchmark tests especially introducing the performance to cost side of the equation. There are many comparisons that pit the AMD processor against rival INTEL in the never-ending battle of who's the best. Read a couple of these reviews and they will show in the multitude of benchmark tests that these processors trade off pole positions. In one test AMD may edge out INTEL and in another INTEL may come out ahead. In most the difference between the two is a matter of seconds, frames, or a handful of points. In real world everyday performance there would be an almost unnoticeable difference in most applications when comparing similar processors.
Bar graphs may show who's ahead but it's important to look at the physical numbers before making a decision. Ask yourself who's ahead and by how much and in what particular application. A 2.8 GHz INTEL processor may achieve more frames per second than an AMD 2600+ in Quake but without insult, the difference is small and most likely unnoticed by the user actually playing the game unless their goal is boasting rights.
That being said what would be another deciding factor? The AMD processor is priced far more competitively than the INTEL processor which means there's more money left over to pocket or spend on more RAM, a better video card or another hard drive.

But you may think GHz to GHz again and wonder why you are paying $200 for an AMD 2400+ (2 GHz) when for another $6 more the 2.6 GHz Intel processor is available. A buyer may think that $6 for another point four GHz may be better. But that's just not the case. Read a review or three and there will be a performance picture that will form. Combine the performance/price analysis with your expectations and then the answer should be clearer.
The final scoff any nay-sayer of AMD product may volunteer is that of stability. Many consumers state the reason for choosing INTEL is due to the perception that INTEL systems are more stable and require less driver updates and tweaking. This may have been the case years ago but is completely false at present. Any system can be properly set up and IF LEFT ALONE will or should continue to operate as intended. AMD systems are stable. If a consumer purchases a pre-configured AMD system from a reputable source they are going to have the same stability experience as if they purchased a pre-configured INTEL system. Large pre-configured PC suppliers go to great lengths to ensure that all of the components as sold work reliably with each other right out of the box. Intel is also the dominant force with far more processors per PC than AMD. Software and hardware developers would choose to align and optimize their product with the processor product that is in more homes and businesses. It's a marketing move. If a consumer chooses to build the computer from individually purchased components then they run the same risk of hardware conflicts and problems regardless of processor choice.
Which processor is better? Which truck is better, Chevy or Ford? I don't think an overall clear-cut winner can be crowned but when trying to build a powerful system within a budget we think of ourselves as smart shoppers by getting the most with AMD.
The mother of all boards
Selecting an AMD based system has other advantages. AMD based motherboards offer a wider range of motherboard configuration options than rival INTEL based motherboards. Which AMD driven motherboard is a matter of the requirements mixed with a dash of personal experience, a pinch of recommendations from friends, a paragraph or twenty from the forums and a page or four or sixty of research.
I admit I've had a preference for ABIT product. I've grown to rely on ABIT for their stability and flexibility. They offer a wide range of choices to suit almost any need. The ABIT AT7 was supplied to us for this system which proved to be really good...and really bad.

Motherboard Pros and Cons
It boils down to a few obvious reasons why this board made the top of the list. The AT7 has the capacity to support an obscene amount of hard drive space. When working in broadcast design with uncompressed video it's going to be needed. External storage solutions of any substance are extremely expensive. The AT7 could feasibly run eight 160 Gigabyte drives off the highpoint controller. That's over a terabyte of hard drive space which is almost 1000 hours of video at DVD quality. As I said before...it's an obscene amount of hard drive space. Data integrity is of a concern but a mirrored array can be easily set up. As a rule, in a professional work environment, projects should and are backed up to external media as completed.
The AT7 has 4 USB headers which is becoming commonplace but is always of benefit. The AT7 also features USB 2.0 support and it's good to have technology that looks forward anticipating options rather than falling quickly into obsolescence.
Two built-in 1394a (FireWire) ports were of great value. Shoving large files (400-800 MB) around a network can be excruciatingly slow. A quick solution was to transfer data to an external FireWire drive and then walk the drive from system to system as it was required and that isn't too often. It's a reusable and fast conduit for large file transfer between the graphic workstations and the edit suite, MAC or PC. It's true. Not every business is perfect and the IT folks just haven't got around to connecting the graphic design workstations with the non-linear suites on their own large bandwidth network.
The AT7 came with other onboard features that presented a cost effective solution compared to purchasing 3rd party PCI cards and these include surprisingly good 6 Channel sound and NIC.
There is only one caution with the AT7 and one issue.
The AT7 does not have parallel or serial ports on the back plane. It is a legacy free motherboard. If there is a need to attach these types of peripherals then the AT7 will disappoint.
The issue with the AT7 was of questionable support of the new AMD Thoroughbred processors. The AT7 wasn't totally compatible with this new series of processors. It was extremely unstable with any amount or combination of DIMMS of Registered ECC ram. Unbuffered RAM in any amount or combination would eventually generate a HARDWARE MALFUNCTION blue screen. This occurred every 3-5 hours for no apparent reason. It is hoped that a future BIOS will fix this or future AT7 boards have been tweaked at the assembly plant.
Please note that a 1900+ Palomino processor functioned beautifully with 4 DIMMS of 256 MB PC2100 memory in either Registered ECC or unbuffered sampling. The AT7 test system chugged magnificently through render after render without a problem. I hope ABIT is focused on the concerns pointed out and will hopefully have a solution soon.
A Clear Choice
If you have the power to do more then you have the power to create more. The final product is then not limited in look and feel by the hardware.
This comment comes from the art director and makes me cringe as powerful hardware costs powerful bucks. Complex 2D and 3D work has a tendency to eat video cards for breakfast. A fast gaming card usually does not have the supporting features and will quickly expose its shortcomings under a task especially in 3D design. Enter a powerful Matrox Parhelia at a significantly less than powerful cost.
A clear choice
The background on the Matrox Parhelia 512 comes from Icrontic's initial review.
The Parhelia-512 is the world's first 512-bit Graphics Processing Unit packed with 256 MB DDR on board. A 256-bit memory interface shoveling out a hefty 17.6 GB/s 275 MHz memory bandwidth.
Matrox is well known for their world class DualHead dual monitor support and now they have taken it one step further by adding a third monitor. The third monitor opens up a new era of gaming that Matrox has dubbed Surround Gaming. How are they going to do this and maintain frame rates AND take gaming environments to the next level? Matrox created a Quad Vertex Shader Array made up of four 128-bit vertex shader engines. Add the highest quality trilinear and anistropic filtering through their 64 Super Sample Texture Filtering. Matrox also boasts that their 36-Stage Shader Array is the most complex rendering engine ever built. Smooth it all out with 16x Fragment Antialiasing (FAA-16x).
SURROUND GAMING obviously wasn't a priority in a video card for broadcast design. It wouldn't be productive for the designers to be fragging away in Quake instead of doing their work. But they still did anyway. The term used was research but I didn't believe that for a minute. Below Softimage XSIoccupies two monitors and the third is available for Illustrator. This is very handy for changing any textures inside Softimage.
Another phrase floating about the Matrox offices these days is SURROUND DESIGN. In the past PC monitors got larger as graphic designers needed more elbow room to work. Then came two monitors providing space to place and there isn't a system in the author's design department that isn't dual monitor. If it's single monitor then it's for e-mail and that's because that hardware hasn't been replaced yet.
Then in came the Parhelia sporting triple monitors and the designers looked at me as if I was nuts. Sebastian MacDougal of Matrox explains:
Matrox Parhelia and Surround Design are enjoying a lot of support from design focused Independent Software Vendors (ISV's) who agree that the more you can see, the more productive you will become. The ability to either spread a project across three displays or having the ability to place various windows strategically across your desktop for better organization is something that workstation users have been asking for, for years. However, in the past it required using multiple cards which drastically reduced performance, and unless you are using Parhelia, this is still the case with competing graphics solutions today. But perhaps the most substantial benefit for the ISV's that we work so closely with is that Surround Design, in most cases, requires no direct intervention at the SW level in order to get it to work, meaning it is very easy for most ISV's to support and the advantages are enormous. To give you an idea, with the current 1.01 driver, Parhelia and Surround Design is optimized for: Softimage|XSI , 3ds max, AutoCAD and Microstation, with many other applications to follow shortly. At Siggraph 2002 in San Antonio Texas, the reception on the part of attendees to Parhelia and Surround Design was tremendous and it is completely understandable. An interesting analogy is how designing on one monitor is similar to a horse with blinders, having three displays just opens things up and allows you to be more productive.
Initially the designers didn't know what to do with the third monitor but in time they began using the extra display each in their own way. Due to the fact that the system had sufficient power and resources they could work in two or three programs simultaneously. For example After Effects is much easier to work in over two monitors and, thus, the third monitor allowed for Photoshop or Illustrator to remain open and easily accessible to adjust or create any elements for use within the After Effects project. The Parhelia has the memory size and graphics processing power to allow for smooth interaction with these programs. Combine this with the strength of the CPU and available system RAM and many a designer were kept happy.
How a user may work with three monitors is up to them but a third desktop enables a user to work within a program that is better suited for two monitors AND keep access to other tools without having to minimize or hide the main program. For example Adobe After Effects stays open in two monitors and Photoshop remains accessible on the third. Pictures above speak louder than words.
One of the Parhelia's strong selling features is, what Matrox has termed, GigaColor. This feature and its benefits were expanded upon in Icrontic's first review.
Dig around and there's a feature that most may not pay attention to but for the 2D/3D graphics professional and even the home user it will mean stunning images right to the desktop. Matrox hung the term 10-bit GigaColor on it. To you and me it is 10-bit video technology and it runs through a very speedy dual integrated 400 MHz 10-bit RAMDAC. That leaves the competition many MHz back. 10-bit technology is the same technology that allows for precise picture control in home theatre DVD players. 10-bit technology can partially be found in high-end video cards that cost thousands of dollars.
The difference is that Parhelia-512 delivers 10-bit technology through the entire card.
It must be told that 10-bit GigaColor still remains a bit of a mystery though it has been literally beaten into my ears by the kind folks over at Matrox. 10-bit GigaColor provides for an increase in the shades of any given color from the standard of 256 to 1024. The color palette leaps up from 16.7 million to 1 billion. This is a benefit when acquiring images such as through the use of a scanner where image control will be to a greater precision at time of capture. A greater range of the shades of a color is available thus greater control over what is kept or discarded is possible. This would primarily benefit print and magazine pre-press artists.
But sadly we people in television deal in comparatively grainy and low rest images and the benefits of GigaColor didn't jump out and bite us on the nose. For the record the designers did notice the desktop appeared more saturated and colorful when it was pointed out to them. You have to understand that designers work with what they have. Technology is not such a big deal. They care about what they can do with it rather than what it has under the hood. Though we would be much more satisfied if the rest of the computer system moved to 10-bit color base but that would mean new technology for
...well...everything.
There is good news on the horizon about GigaColor according to Matrox.
Upcoming OS's from Microsoft (i.e. Longhorn) will include support for greater than 8-bit per color channel precision at the desktop level, which is why you are seeing more and more companies include support for higher precision color depths. But of course, we were the first and are the first shipping product to offer that functionality, and as we make our own boards you know you'll get the right components for sustained image quality
The designers were quick to adapt to the flexibility the Parhelia offered and enjoyed working in an environment that produced clear, crisp images to the desktop. The only drawback is each of them would like a Parhelia of their own and 3 digital flat panels. That means a few more dollars added to this year's capital purchase forms. More paperwork....just what I enjoy.

The heatsink is also just another player in the heat game. As the Case Cooling Tweaks articles point out the correct choice of a PC case and additional fan modifications can help win the battle against heat and noise.
On the Case
Breaking out of the beige box...the right way.
AMK Computers came to the table with the SX1000 and set up a workstation case that delivers looks, cooling efficiency and a few other treats. The base SX1000 case comes standard with
- Space 4 drives in a removable bay
- Space for a zip and floppy in a removable bay.
- fan mounts (two front-two rear)
- space for 4 external 5.25 inch drives
- locking access panel
- locking front drive cover
To this AMK added:
- A side window with 2 more fans
- A top blowhole
- VBLOCK sound dampening material
- Cable Loom
- Rounded cables
- Digital Doc 5
- Enermax 465 PSU (FC)
- Fan filters
The neon lights were thrown in for this article just to make the case look better. I think they add a few MHz here and there due to the fact the case looks faster.
Seven fans plus the two Enermax PSU fans and heatsink fan may seem like a lot and loud. Quite the opposite as all the case fans were kept to ADDA 25 CFM/ 25 dBA specifications and regulated by the Digital Doc 5 fan controller. When the fans were not needed they were shut off. Only two fans, the top exhaust blowhole fan and one of the rear exhaust fans, were kept constantly running. (In addition to the PSU and heatsink fans). The two always on fans provided continual airflow yet emitted a minimum of noise. Again the computer in non-stress applications or when not rendering ran at below 30 dBA...less than a normal whisper.
The heatsink is warmed by the processor as the system was stressed. The fin design of the CAK4-76T allowed for the tips of the Digital Doc 5 thermistors to be inserted between the fins. This did not block airflow but this configuration allowed the Digital Doc 5 to directly read the temperature of the heatsink. Fans were turned on or off in a preset order to compensate for the increases or decreases in temperature. A full roar my cat was louder.
The last cooling tweak was to apply the WPCRSET tweak to enable the CPU halt command. This halts the processor and allows it to drop 5-10 degrees Celsius off pre-tweak levels. Besides updating the drivers the WPCRSET tweak was the only software OS hack if it could be called that.
In order to test this configuration a SOFTIMAGE project followed by an After Effects project were rendered out. The Softimage render took approximately 50 minutes (the first flat peak) and the After Effects render (the second peak) took 10 minutes. The following graph shows the temperatures never exceeded 46 degrees Celsius (23.5 C room temperature) which is only a 10-12 degree Celsius increase over base line temperature. That's a very satisfactory result especially with a system that operates through a range of 25-35 dBA.
The neon lights are available as an option and it was rather humorous watching designers and other employees wander by, stop, and back up to take a second look. Most came in and peered into the side window of the PC and said the word cool a lot. It is true that these people know of nothing other than the beige box. They asked why the window? The answer was why not?
Computers can become very dusty even in apparently clean offices. Filters are the solution to greatly cut down on the amount of dust that collects and clogs a PC after months of use. Filters do reduce airflow but they are worth it. A picture is worth a thousand words and this was the result of only 3 weeks of operation. The fans these filters covered were also not spinning at all times. This dust was the result of what was sucked into the case (or tried to be) from the airflow generated by the back plate and PSU fan. The filter on the left is clean and the one on the right...ugh.
The plethora of benchmark programs can be important when determining what does what task faster or better. These are specific assessments of individual functions. For this article it was decided to add a few more of what is our assessment of real world tests. It was also thought important to show how a change in one particular component could affect end results. It is hoped that the result of these tests will help you assess priorities in system configuration to match the priorities in system expectations.
