The Card and The Test
Well, we don't know what NV45 will be called, we don't know when it will be available, and we don't actually know if these are the final clocks. But that's what we get with a preview or first look. Please note that these speeds could change before the final product is released. Our NV45 is running at 435MHz core and 1.1GHz memory. If our 6800 Ultra Extreme sample from NVIDIA had not been DOA (despite a couple hours of on-site BIOS flashing help from NVIDIA's Jim Black), this is the speed at which it should have run.Of course, we are hearing something closer to 460MHz core clock (1.2GHz memory) for most vendors who have 6800 Ultra Extreme parts coming out, but that remains to be seen. In any event, since there's no real performance impact, we will finally be able to bring you numbers that are representative of what we should have seen, if we had gotten a working Ultra Extreme sample. Of course, it's on a 3.4GHz P4 EE running DDR2 RAM, so it's not really comparable to the number that we ran on the AMD Athlon 64 3400+, but we have some vendor's 6800 Ultra Extreme parts coming to the lab soon enough, and perhaps before then, we'll switch around our graphics test platform a little.
Here's the test platform we used.
| Performance Test Configuration | |
| Processor(s): | Intel Pentium 4 3.4GHz EE Socket 775 Intel Pentium 4 3.4GHz EE Socket 478 |
| RAM: | 2 x 512MB Micron DDR2 533 2 x 512MB Corsair 3200XL (Samsung 2-2-2-5) |
| Hard Drive(s): | Seagate Barracuda 7200.7 |
| Video AGP & IDE Chipset Drivers: | Intel Chipset Driver 6.0.0.1014 Intel Application Accelerator 4.0.0.6211 |
| Video Card(s): | nVidia NV45 nVidia GeForce 6800 Ultra PCI Express nVidia GeForce 6800 Ultra AGP 8X ATI Radeon X800 XT PCI Express ATI Radeon X800 XT AGP 8X |
| Video Drivers: | nVidia 61.45 Graphics Drivers ATI Catalyst 4.6 beta |
| Operating System(s): | Windows XP Professional SP1 |
| Power Supply: | HiPro 470W (Intel) Vantec Stealth 470W Aluminum |
| Motherboards: | Intel 925XCV (Intel 925X) Socket 775 Intel D875PBZ (Intel 875P) Socket 478 |
And here are the numbers that we've all been waiting for.

How did this get eh NV45 label? Shouldn't this be the NV40p or sum'n?Minotaar - Monday, June 28, 2004 - link
Pentium Pro did NOT have on-package cache. Pentium Pro had On-DIE cache. Pentium 2 took a step backwards and had on-package cache (that huge ugly slot garbage, with the triple fans from OC co's like Glacier? The side two fans cooled cache chips on the side). It wasnt until Socket P3 that on-die cache came back.Thats why celeron happened the way it did. it started off as a p2 with none of the on-package cache. Remember the ol' celly 266 that OC'd to 450, and for some lucky ones 504? Well That was just the P2 card without the cache on the sides - the sides were empty.
Pentium Pro also had the advantage of clock speed cache, whereas P2's cache was bus speed. But I digress. The article has an inconsistancy.

Well, you're not going to gain anything in the near future with PCIe, so if you already have an AGP card, don't bother.It would probably be a good idea to get a PCIe card if you're upgrading to the new Intel chipset though. The boards that have both PCIe and AGP slots are running the AGP slot off of the PCI bus, so there will be a slight performance penalty associated with that.

So is AGP8x faster or better than PCIe, because that's what I got from those earlier benchmarks. Or will drivers and optimizations change that in the future?Basically, is it worth while(money) to purchase PCIe now?
