Re: it's the fillrate cheese! evil!
The slashdot crowd is absolutely bloody right to expect that 10 years later something with the visuals of Quake and the level of game AI complexity of Nethack should have been written released and shipped.
And that has not happened. The monsters in the newer quakes, dooms and the likes are as daft as in the original. There is no random or even pseudorandom level generation.
A factor may be we have had too much focus on screenshots, and not gameplay and scene interaction. 3D hardware accellerators "GPU" is big business and have been very competitive last years, they don't wanto risk huge investment into physics and geometry accelleration.
Sure we have bumpmapping and vertex shaders but these are non-interactive one/way effects only.
After Ageia released the PhysX Physics Processing Unit "PPU" we actually have hardware specialized in accellerating the interactivity in geometry (objects and architecture of polygons). And as business is business and business must grow, NVIDIA and ATI was afraid the focus would shift from the GPU and quickly responded with their GPU-as-PPU PR crap. A GPU-as-PPU can never really be a real PPU. It may be many times faster in some situations but is still a quack hack. Even if it "evolves" I still fear GPU-as-PPU will never be as good as a solution built from ground up for physics and scene interaction (think satisfying death animations and destructive architecture).
- The lack of a real write-back method on the GPU is also going to hurt it in the world of physics processing for sure. Since pixel shaders are read-only devices, they can not write back results that would change the state of other objects in the "world", a necessary feature for a solid physics engine on all four counts.
- Another interesting issue that AGEIA brought up is that since the Havok FX API, and any API that attempts to run physics code on a GPU, has to map their own code to a Direct3D API using Shader Models then as shader models change, code will be affected. This means that the Havok FX engine will be affected very dramatically every time Microsoft makes changes to D3D and NVIDIA and ATI makes changes in their hardware for D3D changes (ala DX10 for Vista). This might create an unstable development platform for designers that they may wish to avoid and stick with a static API like the one AGEIA has on their PhysX PPU.

Re:Maybe per watt performance is the best but...
While that may be true, let's not forget that the CoreDuo is still intended as a mobile processor. The fact that it is even competitive with the X2s is impressive. The real test will come when the Conroe comes out. Early reviews (granted, on intel supplied hardware) show Conroes kicking the crap out of even the fastest AMD processors (overclocked even) in everything from gaming to media encoding and synthetic benchmarks. They are cooler and more efficient to boot. Unless AMD pulls some magic out of its hat, my next rig will be Intel based. See here: http://www.pcper.com/article.php?aid=219&type=exp

I smell a Beowulf reference...
I'm inclined to crack jokes, but I've been out of the game for a long time so I have questions. Better do both.
- I couldn't really tell, but in the images it only looks like the mobo has one cpu. Just one? I imagine the kind of frea^H^H^H^H consumer who would go for 4way SLI would demand nothing less than 2 dual-core CPU's.
- If it does only have 1 cpu, or even 1 dual core cpu, wont the games be CPU limited before you even scratch the surface of this qual-sli madness?
- They've drawn flames on this thing. I imagine this is redundant given the heat it will produce, and ultimately confusing to the jerk^H^H^H^H consumer when it actually does burst into flames. :-) -

The case is actually made of a clear material.

Dual video cards?
I've tried out the SLI configuration with two NVidia cards and saw a substantially smaller than 100% speed improvement. It was pretty difficult to set up in the first place, as these people found out.

Re:Real speed != clock speed
Performance per watt? Intel?
Not likely...
The pentium D is putting out as much as 233 watts.. (http://www.pcper.com/article.php?aid=145&type=exp ert&pid=17)
Compared to 89 watts on the athlon X2. (http://www.tomshardware.com/cpu/200508011/athlon_ 64_x2_3800-03.html)
Maybe they should label them according to number of bogomips or mflops instead? -
Re:Honestly...
obviously you missed the fact that when gaming at 1600x1200 and are using 4x antialiasing and 8x anisotropic filtering that the x1800xt beats the shit out of the gf7800.
if you're buying a 500 dollar card, are you seriously worried about benchmarks that are run without aa+af? this card even does HDR (hi dynamic range) plus AA, something that the gf7800 can't.
this card is way more sophisticated and highly refined that the brute force 7800. the 7800 isn't bad but that this card can do with 16 pipelines what the 7800 can't do with 24, says a lot.
and that's just raw performance with todays games. never mind the fact that the 1800xt comes with 512megs of super fast ram... ready for well into the next generation of games, whereas 256meg 7800's are already obsolete for the high end of the next generation. sure 256 will be enough if you pare down the resolution and lower the texture detail. one example is the game F.E.A.R... on the 1800xt it absolutely trounces the 7800 in performance.
my advice... read ALL the reviews you can get your hands on. there are too many discrepencies if you only read one or two. if you want to get a more full picture, get to reading.

my own PSU huntDisclaimer: I don't work for any PSU company, just another programmer/puter geek here.
About 6 months ago, one of my cheap free-with-case PSU's died. I went on a mission to find a good bang for the buck PSU to replace all 3 of my systems with high quality PSUs. I read several tests and reviews, including the one on Toms and another http://www.overclockers.com.au/article.php?id=359
8 67 and another http://techreport.com/reviews/2004q4/psus/index.x? pg=1 and not to mention http://www.pcper.com/article.php?aid=-270.The conclusion? I went with FSP power supplies labeled as Fortron or Sparkle Power. Yes, you can get nicer more expensive ones, but for a very low price, these beasts couldn't be beat for price/performance. I opened up 300w Sparkle, a cheapie 400watt free with case, and my friends ThermalTake which was fairly pricey rated at 350watt. In terms of size of capacitors, mosfets, heat sinks, etc, the Sparkle definately had the edge in size (size does matter with this stuff!). I replaced all 3 of my systems with these and they are humming along great.

AMD's dual core offering better than Intel'sAccording to various preliminary benchmarks from The Tech Report, Tom's Hardware and AnandTech, AMD's desktop dual-core chips are significantly better than Intel's dual-core desktop offerings in terms of performance and power consumption. This is partly due to the fact that the AMD solution has a better inter-core communication architecture and lower memory latency.
Meanwhile, Intel's desktop dual core chips seem to offer much more aggressive pricing at this time. AMD's lowest price dual core chip, the X2 4200 is almost twice as expensive as Intel's lowest cost dual core processor. However, an interview with three AMD execs on PCPerspective.com claims that "AMD would eventually have lower priced Athlon X2 processors via the waterfall effect in the future".

Re:PPU is the answer.
Dual-core will most likely render PPUs obsolete anyhow.
That's what I thought at first, but according to Ryan Shrout from PCperspective:The information I have gotten from AGEIA seems to point out that while a single core CPU might be able to hand 200-300 rigid bodies, a dual core CPU could handle 400-600. Compared to the PhysX PPU, which can do over 15,000.
This is from the interesting discussion at http://forums.pcper.com/showthread.php?t=390476&pa ge=3&pp=15.
Apparantly the currently expected MSRP for this PCI card (vertices don't need as much bandwidth as textures etc) is $249-$299 and it's expected in Q4 this year.
The next Unreal engine uses it. I'm excited. -
Re:Makes you wonder
Well actually Semprons, Athlons, Opterons,
Sempron vs Celeron = http://www.pcper.com/article.php?aid=61&type=exper t&pid=5
Sempron out performs the Celeron on the Game front, but they are pretty neck and neck on the desktop front.
Athlon vs Pentium 4 =
http://www.tomshardware.com/cpu/20001206/p4-11.htm l
ergo, " If you have dedicated areas in which you want your computer to perform particularly well, if those areas should be 3D gaming, video encoding or other bandwidth intensive software and if you should not shy away from high system costs and the missing upgrade path, you should indeed consider Pentium 4. However, if you want a balanced system with excellent performance at a good price I heavily suggest Athlon...."
Itanium vs Opteron =
http://www.tomshardware.com/cpu/20030422/opteron-2 8.html#conclusion_linux_servers_smile_and_workstat ions_worry
Ergo....A fairly even heated match.
The Point being to say that 1 processor is why AMD has the right or not the right is kind of a rather narrow view. All three of AMDs Procs either match or beat Intel based product.
Antitrust away AMD. Im behind you all the way. Cheaper product that "just works" is far better than monopolistic product that costs too much. -

Re:AMD == not more stable

Have you tried using > 4GB on your AMD64 ? If you are like me, you get daily crashes. Why ?

AMD64 systems have proplems with fully populated DIMMS. Crap like this is unacceptable to corporations purchasing 1000's of boxes. It is also unacceptable to DELL. Every customer problem cost DELL money.

78%
The other thing I just noticed is that on this page, you can clearly see a picture which shows that Half-Life 2 is only 78% "downloaded", after "buying" the game.
I put "buying" in quotes here, because I don't consider 78% of something to be the complete product. As far as I'm concerned, Valve and Co. should be responsible for the remaining bandwidth I need to waste completing the download.

Re:Multi-processor
Interestingly, Alienware is planning a dual-Xeon gaming system, with two PCI-Express video cards: one rendering the top half of the screen, the other rendering the bottom half.
Check it out here or here. Or from the horses mouth here.
Since they chose a dual-Xeon setup, I would assume such a setup is either a good choice for gaming or just sounds pretty to the marketing department. That said, Intel will soon begin to put out dual-core CPUS, so some of the game programmers out there are probably contemplating games designed around a dual-CPU core setup, rather than mere hyperthreading. -
Re:Toys for the rich
Actually, Nvidia and Alienware are both working on solutions that accomplish this goal. Nvidia's solution is their own (called SLI, probably because they gobbled up 3d Labs -- remember the Voodoo2 boards you could link up?), while Alienware's is (video card) manufacturer independent and based on technology from Metabyte a/k/a Wicked3D. The performance is promising (with gains from 70-90% on various benchmarks).
You can read about Nvidia's solution here, and Alienware's here. The problem is that two x16 PCIe slots are required (PCI-Express, not to be confused with PCI-X which is a different beast altogether). Right now, the only manufacturer shipping PCIe enabled boards is Intel, and even they didn't last too long (see The Grantsdale Recall), but none as of yet have two x16 PCIe slots, other than the "x2" motherboards which are custom OEM to Alienware. I'm sure that in the near future the major tier one motherboard manufacturers like Asus and Gigabyte will provide these solutions as well, but it remains to be seen what kind of price premium can be expected (other than the cost of a second video card!). -
Cooling Requirements?forget power requirements, what about the effin cooling? Does it strike anyone else as extremely stupid to put two scorching hot graphics cards back to back? I mean... come on!
Alienware took a very different tack with their solution because it requires a 3rd PCI slot AND it's analog (3rd & 4th pics). I guess its a series of tradeoffs: Space vs flexibility, with Nvidia winning the battle for space but losing on flexibility.
That aside, its rediculous that nvidia is expecting their OEM cooling solutions to do any kind of justice to the heat from those cards. Alienware already expects water cooling to be part of the solution and has cases designed accordingly... couldn't NVIDIA have done it any other way? Do they absolutely have to have a hardware link between their cards?
"A power draw of 250 Watts for the 6800 Ultra SLI solution is very realistic."
Then explain how this will work. -
