Pentium 4 And Brookdale Update

I've been told performance isn't related to size.
This is not targetted specifically at home users... This is supposed to be the flagship product of Intel...
I will guarantee, though, that the benchmarks that will be run will not take this into mind. You will see Quake3, Incoming, Winbench, and the like used to see what the processor will do. Great. Fine. Here we have software that is either bound by the bottle neck of the GPU, memory bus, or some other technology that is holding things back. Even those programs you mention will be limited in some way regarding these technologies. Bah, I say.

"There will be two versions of the Brookdale chipset, an SDR and a DDR version. The SDR version should hit the market in September of 2001. The DDR version should hit in January of 2002, though there is a chance that it will arrive as early as October of 2001."
Anyone else this Intel would find itself losing a considerably larger market share than it already has if the P4 can't use SDR or DDR for almost a year from its release? I sure do.
> Obviously, the pentium 4's performance lags (or will) behind Thunderbirds of similar clock speeds. But this thing is also a .18 die process.
.18 micron process. This means that an individual gate measures 0.18 micron wide (or is it long? Damn...where's my VLSI text). Now, the smaller you make each individual gate, the more gates you can pack into the same square area of silicon. Or, if you keep the same design with the same number of transistors and "shrink" it to a smaller process, the same part can be manufactured in a smaller die size (square chunk of silicon).
You are being a bit loose with terms. The Pentium 4 is fabricated with a
Cost for semiconductor manufacturing is primarily a factor of silicon area, so reducing the die size is a big cost-savings per part. Also, smaller die sizes increase yields. Defects are inevitable, but with careful fab management, you reduce defects to a certain number per wafer. Each one of those will (likely) ruin a die. But if the dies are smaller, less of the overall wafer's area is lost to that particular defect. Thus, the smaller your die size, the less any given defect will cost you.
But there's another very important advantage you get from a smaller process. A smaller process generally translates to a higher clock speed. Why? Gate capacitance. Each gate is essentially a capacitor that has to be charged or discharged to switch the gate on->off or off->on. A larger device has a greater capacitance and hence takes a longer time to charge/discharge. So, larger devices take longer to change state, and hence can not be clocked as fast.
So, in summary, a process-shrink should improve yield for Intel, which means lower cost per part. It should also help their engineers up clock speeds on the component. However, at any *particular* clock speed, performance will not be affected. Heat dissipation / power consumption should be reduced, but otherwise, clock for clock the consumer will not notice a difference between processes.
...anyway, that's some of the engineering behind this. In terms of forecasts, I think Intel has been caught with it's pants down. They have an inferior product, and, if the world is sane, AMD will clean their clock in the coming year.

I'm not worried about that. My Celery 300A system will be in service until 2002. The motherboard only supports CPU's up to 550 MHZ. When I bought the thing the fastest Celery processor was 433 MHZ.
I have no high hopes that I will be able to put a 2 GHZ processor in that board, so I guess that it was an evolutionary dead end.
I have never upgraded the processor on any of my computers without switching the motherboard as well. I just run them too long for that. I typically run a computer for at least 4 years, and my current machine will go for 5 years.
My next machine will be 1000 times faster than the 386SX that I used from 1990 to 1994, so I expect that it will serve me even longer.
If tits were wings it'd be flying around.

Hey 1.4Ghz means that the buttons on Java GUIs will go up and down almost in *real-time*. Wow. those wierdos in the Java development camp will be dancing in the air!
I mean, if they can't get the thing to 5+ gigahertz speeds, will it be very effective at all in the consumer marketplace?
What planet do you live on? Because on mine, most people are getting by quite nicely with 200 to 500 MHz processors. Some get by with a lot less.
I HOPE that the P-4 wasn't designed with 5GHz speeds in mind, solely because it'd (probably) have to be so optimized for those speeds that such meager speeds as 1.5 GHz would suffer as a result.
Yeah, Moore's law exists. But that shouldn't make us suppose that a chip that might not reach 5 GHz comfortably is dead in the water.
"First of all, I was wondering if maybe Intel could some up with some more creative chip names then just using stupid numbers...at least with AMD you have Duron and thunderbird and stuff....intel has Xeon and Pentium 1,2,3,4."
Actually, Intel's simplistic naming scheme makes sense with the national market in mind. Joe Consumer sees computer with "P4" and immediately knows that it is faster than the one with a "P3" since 4 > 3. Next to those, he sees a "Thunderbird", "Duron", and an "Athlon". Those sound fast and powerful, but you never know. However, he knows for sure that a P3 is fast, and the P4 must be faster. Better safe than sorry, and he buys the P4 system.
The problem with cool names (and I love cool names) is that they tell you nothing about the product and thus provide no way to remember what name corresponds to what level of performance.
So while simple numbers are boring, they aid the consumer. Cool names, while catchy, don't necessarily help, and may confuse.

First of all, I am a software guy and I took only as many hardware classes as were required, so consider most of the following to be phrased in the form of a question (as in "Does this make any sense at all?"). That said:
It seems the speed of light must be becoming a significant factor here. At 1 GHz, light in a vacuum will only propagate about 30 cm during a clock cycle (3*10^8 m/s / 10^9 cycles/s = 3*10^-1 m/cycle), and at 5 GHz that drops to 6 cm. I don't know the speed of electrical impulses in silicon, but even if it's not much less, that means a signal can't be doing too many laps back and forth across the chip (up and down the data path, etc.), i.e., you're working in a time scale where you can see the clock pulses rippling across the chip. Then no matter how fast the gates themselves are switching, the number of them that the signal can go through is limited by the time it takes for it to travel the total distance.
When the speed-of-light propagation time from one end of the chip to the other is a measurably large percentage of the clock period, that would seem to make for some incredibly funky new design problems, due to clock events having occurred in one place but not another, signals that take different paths not reaching the same place at the same time, etc. Or if you just wait for everything to catch up between steps, that would cut down the number of steps per cycle even more. This would be another reason why smaller feature size allows higher clock rates for the same design: it reduces the distance the signals have to travel.

But requiring a redesign of the case so the heat sink can mount through the board to the backplate? That's excessive in my opinion... Many of the other manufacturers don't have chips with such a high clock, but these other chips seem to have a better overall design and don't need to be overdriven like the poor ol' x86 line...

Of course that kind of "being optimized" applies. Additionally, a 10GHz chip better have a hell of a lot more bus bandwidth than a 1 GHz chip. You said something along the lines of "I hope the P4 isn't optimized for 5Ghz because then it wouldn't work efficiently at 2GHz." The P4 is optimized for high clock-speed in general. It takes the 20 stage pipeline just to reach 2GHz and the chip is capable of reaching 5-8 GHz or so. That's about the same range as the 60Mhz Pentiums reaching 233 or the 233MHz PII's reaching 1000Mhz (with the PIII) I thought you were implying that clocking a chip meant for 5Ghz at 2Ghz (given the same architure) would somehow decreased the performance more drastically than the decrease in clock speed would account for. My mistake if I underestimated you.

Well it seems to me that whereas the latest Intel offering is a large, bloated, energy consuming pile of whatever, it still will command some degree of market share due to the number of SMP offerings out there. If anyone can tell me where I can find a Dual or SMP Athlon board, email me immediately.
Whereas the Pentium IV has NO motherboard support and Rambus vs DDR, the race is now on to see who can produce a good SMP motherboard first. The frontier really is in multiprocessor now, not just the clock speed of CPU0.
I mean, all toaster jokes aside, is this finally when we start to realise that we either gotta start going RISC, or start looking at other options (photonics?) rather than silicon?

i haven't heard one industry expert (expert mind you, not pcmagazine/ziff davis moron) who thinks the p4 will even sell more than the pentium pro did. the p4 is the worst-designed intel chip ever, purely designed by marketers. reward innovation. don't buy intel right now.
Um, NVIDIA is a relativly small company but you'd never know it from their release dates. They don't own any manufacturing capability, they only became a player in the last two years or so (after the TNT). ATI still sells more chips than them. Microsoft only releases its products every two or three years. Office has gone through 3 releases in 5 years (95,97,2000) NT4 took more than three years to get to 2000, and in the last 7 years, MS has only shipped 3 releases of Visual Studio (4.x, 5.x, 6.0) They don't release often at all. Your comment has some merit, but your totally of base on why MS brings out inferior products. MS pumps out crap because there is nobody to challenge them. Notice how after Linux came out, Win2K came together startlingly well. Aside from Microsoft, there are only a few companies that use their monopolies to turn out crappy product. ATI for example. Intel in general DOESN'T turn out crappy products. I have no idea why people have a beef with Intel, because in general their products kick ass. I think the major reason you've been seeing problems out of Intel lately is because their in an unusual position. They are not used to being in the position where their solutions aren't the fastest. Remember, Intel might be a monopoly, but only because they had industry leading performance. They don't anymore and I think they're stumbling in trying to adjust to the role of not having the freedom to decide their own release cycles.

You arent really supposed to buy one now.
.13micron soon.
Why?
Because of several reasons
1)The chipset is quite large and it will be migrated down to the
2)It potentially will reach speeds of 4Ghz, just wait for them to get it up to 1.8-2.0 and watch AMD fumble the ball. The P4 at 1.4 is only about as fast as a P3 at 1.1 anyway.
3)The Price obviously
4)Like the article said it doesnt support most memory types now, so when it does it will drastically improve performance. Why, because memory speed is the primary limiter for processor performance. Why do you think Intel tried to do that whole Rambus thing??? If you have fast memory it helps your processer out a lot.
Personally Im going to wait for someone to make a mobo that supports the 64bit Itanium, or two of them! then run BeOs -drool-.
Athlon and Duron are gay names. I liked K7 and K7-Consumer better. More dignified and all that. (I would have settled for SpitFire too, but Duron?)

Who needs a PIV when you can get a PIII 1GHz for for about $460. And with the prices dropping about $20 a week, hey, its gonna be worth it to get one (or two) by the time the PIV is even officially released.

Performance is not linear.
Comp Org 101
Wasting cycles
When you increase the clock speed you also need to increase the rate it receives data. The P4 is optimized for higher clock speeds than 2 GHz. You can expect this chip to reach near 10 GHz. This is due to the 20-stage pipeline. Without a 20 stage pipeline it will be sitting there wasting cycles.
Cache misses - too big a pipeline
You have a 20-stage pipeline and you have a cache miss. The whole pipeline must be dumped when there is a miss. The bigger your pipeline the bigger your odds of a miss. The CPU must go to memory to get data since the pipeline is wrong. It may have to go to L1, L2, main memory, etc.
Slow clock - smaller pipeline - less performance hit
So, if you have a slower clocked CPU you make the pipeline smaller since its need for data isn't as bad as a CPU that is clocked at 5 GHz. This makes it easier to design, puts less emphasis on brach prediction, and makes it less costly.
Not Linear
The CPU's performance is not directly related to clock speed. It is definitely not linear. There is an elbow at the end of the graph. The beginning of the P4 graph will not be linear either, start out slow. Performance will not be in direct relation to GHz.
History Repeats Itself
Doesn't anyone remember when the Pentium classic came out? 486s were running circles around it. The Pentium 233 MMX is faster than a Pentium 2 233 with 16-bit code.
So you know: Pentium classic has a 5-stage pipeline, P2 & P3 has 10 stages, P4 has 20 stages. Athlons have 10 and new Athlons have 12.
Ok, so you can get the chip now, I've even seen it on pricewatch, but you can't get the motherboard. Now Intel can blame the lack of PIV systems on a lack of supporting hardware and hope the average consumer doesn't realize that it's Intel's fault that there isn't a chipset that can handle the "power" on this new chip.
WARNING: there is a trojan on your

Itanium (code named "Merced") is the first implementation of Intel's new architecture dubbed IA-64. IA-64 is the long-awaited replacement for the geriatric x86 architecture. Intel developed this new architecture jointly with HP. (actually, truth told, what is now IA-64 was originally HP's internal project to replace their PA-RISC architecture. Intel hopped on board sometime later)
Itanium has been in development for quite a while, but has been delayed time and time again. The project has hit all sorts of roadblocks, one of the most fundamental of which has been the lack of efficient compilers. The IA-64 is radically different than x86 chips or even RISC-style chips. Architecturally, it is a VLIW (Very Long Instruction Word)-style processor. This type of architecture simplifies the construction of wide superscalar designs (that is, processors that are capable of issuing multiple instructions in a single cycle). It has good theoretical performance, but is considerably more dependent on compiler technology than more traditional designs.
Very few processors have been designed in this style, and the corresponding compiler technology is still rather primitive. This, along with internal problems at Intel have greatly delayed the first implementation.
Infact, the part was supposed to be out right now. Obviously it isn't, and Intel, realizing it wasn't going to have Itanium in time to compete with suddenly-relevent AMD's K8 product, panicked and had to put Itanium on the backburner to piece together another x86 to have something to pit against AMD. Hence, the Pentium IV was designed. Intel wanted to be beyond x86 processors by now, but the delays in design of Itanium forced them to squeeze out one more x86 to feed the market.
Comically, the second generation of IA-64 (code named McKinley) is being designed at HP and has been progressing quite nicely. So much so, that some people fear McKinley will actually beat the older project, Itanium, out the door. With this as a possibility, the question of whether Itanium won't be scrapped altogether arises.

How old are you? Are you new to computers? What chip release from any company hasn't been exactly the same? Hardware technology has always outrun software speed needs. Games are always behind the latest hardware for one simple reason: why would you write software to run on hardware no one yet has? That's like selling a railroad car in a country with no railroad tracks. It's simple economics. If you've ever, ever, ever bought a computer, you know that the best value for the buck is to purchase a model that's at least a little older than the very latest. When P IIIs came out, P IIs sold like crazy because they were more than sufficient for most people and prices dropped. There's certainly nothing out of the ordinary here. All initial releases of first generation chips by Intel cost over $1K.

Third of all, they are using
also..I heard some talk (rumors..not necessarily true) that a new powersupply is needed as well. This new Pentium 4 chip is full of heat, sucks up the wattage, and requires redesigned cases and mobos.

Actually, 3D modeling is entirely processor limited. It is fairly light on the memory bandwidth, and final rendering doesn't use the graphics proc (anyway, 3D modling tends to use geometry *MUCH* more than games do. If you ever look at Pro level OpenGL accelerators, their fill-rate sucks, their geometry engines.) Also, P4 will bust out some serious bandwidth. I don't know how P4 will do on server apps given the pipeline, but for 3D and media processing (which tend to have few branches to miss) will absolutely SCREAM on a P4.
A deep unwavering belief is a sure sign you're missing something...
Why does everyone assume that everyone runs the same thing? Run whatever suits you. If you crunch code all day long, then a lot of RAM and an older proc is probably ideal. If you run spreadsheets and productivity, then a fast harddrive and an older proc is great. If you're like me and need programming, 3D modling, and gaming, then getting the fastest proc (maybe a bin or two down, 1.1GHz instead of 1.2 since 1.1 is very fairly priced) and a fast harddrive with a lot of RAM is really the only option.

I'm sick and tired of trying to keep up with the advances in this technology, only to find out that there's always some glitch or gotcha that gets 'figured out' in the next generation of components.
Frankly, I don't give a crap about mHZ ratings or benchmarks any more. From now on I'm going to base my component-buying decisions on whether or not the company is *honest* about the problems with its product lines, and whether or not they fix them, standardize on ways to do things that won't isolate existing customers when newer revisions become available, etc.
Right now I have an AMD 750 CPU in my main development system which runs just great. It's not the fastest computer I've ever used, but it is *plenty* fast, and I probably won't need to upgrade it for at least another year (hopefully).
I also have a Mac G4, which, for as much as I've despised Apple for Mac OS9.0, is a really, really terrific architecture. Sure, it's not a dual-proc machine, but it is *fast*, and it's *EASY* to upgrade.
Being a long-time computer geek, I've come to appreciate this simplicity of Apple gear more and more - to the point where the x86 way of life is really just too frustrating. Give me Mac OX X on a fast and well-designed G4, sitting in an *available* (i.e. non vaporware mobo) architecture, with sufficient RAM bandwidth and i/o options (Firewire rocks serious ass), and I'm happy.

You are wrong about the P4... it's not targetted to the server market. It's targetted to the high-end desktop and workstation market. Itanium is thier server product, as it's thier new 64-bit architecture.
The P4 is going to fail for one reason: RAMBUS. They are contractually forbidden to make a DDR-SDRAM chipset for it. DDR-SDRAM is cheap, and faster than RAMBUS.

I believe it's Transmeta's lies that are going to do them in. They claim their chips will only use 50% as much battery in laptops extending the life out to a day. Since CPU's only use 25% of the power I'm sure even the trolls can see how this is impossible. At IBM we have not been able to reproduce thier claimed results and Transmeta refuses to show their data proving it.
You asked me to name apps that need the power and I did ;) If you're a 3D developer, 1GHz is really useful. As for the games, yea, they'll run pretty well at 500Mhz, but for optimum playability, you need at least 800MHz with a GF2 (which is actually quite affordable if you're upgrading, especially for Athlons.) It just depends on what you use.

Rather than a revolutionary new package to compete with AMD it's something pushed out the door long before its gestation period is up, rudely stamped, deformed, unfinished, sent into this breathing world scarce half made up, and that so lamely and unfashionable that dogs bark at it as it halts by them.
Oh, sorry.
Look, Intel screwed the pooch with the whole Rambus fiasco and not figuring that AMD would EVER be real competition. Now they are behind and scrambling. The P4 is a stopgap measure to get SOMETHING out the door that they can call new and great.It also complies with the already repudiated Rambus contract that they are trying like mad to get out of. They plan to dump the whole thing as soon as they can and cease all support for it.
I don't blame them either.

Why would anyone want one of these chips? Looking at Pricewatch, the chips are going for nearly $1k! Meanwhile, you have a great Thunderbird going for $480'ish. Currently, the low end systems for most games are still running PII 266 with a good Voodoo2! With a combo of Athlon/PIII and a good GPU from Nvidia, you will have a system that runs the latest software at the greatest of speeds. I am sure that Intel will release a great benchmark tool that will demonstrate why we need it, but my question is where is the software to really demonstrate the power of this chip?
