The Card and The Test
This is our NVIDIA GeForce 6800 Ultra engineering sample. No, it's not one slot, yes, it has 2 molex connectors, and generally its actually not very loud.
The 16x1 GeForce 6800 Ultra will be clocked at 400/550 (core/mem) and priced at $499, while its 12x1 little brother the GeForce 6800 non-ultra will be priced at $299 (clock speeds to be determined).
Here's a quick rundown of the key features:
. Vertex Shaders
° Support for Microsoft DirectX 9.0 Vertex Shader 3.0
° Displacement mapping
° Vertex frequency stream divider
° 65000+ instruction length programs
. Pixel Shaders
° Support for DirectX 9.0 Pixel Shader 3.0
° Full pixel branching support
° Support for Multiple Render Target (MRTs)
° 65000+ instruction length programs
. Next-Generation Texture Engine
° Up to 16 textures per rendering pass
° Support for 16-bit floating point format and 32-bit floating point format
° Support for non-power of two textures
° Support for sRGB texture format forgamma textures
° DirectX and S3TC texture compression
. Full 128-bit floating point precision through the entire rendering pipeline (64-bit max precision to framebuffer and display)
The chip is 222 Million transistors fabbed on a .13 micron process. Currently a 480W power supply and 2 free completely independent connections to the PSU are required. 8x Rotated grid multisample antialiasing, and 16x (128tap) anisotropic filtering are available.
Our test system:
AMD Athlon 64 3400+
1GB DDR RAM (OCZ Platinum at 2-2-3-6)
Seagate 120GB HD
PC Power & Cooling 510W ATX Power Supply
Other cards used in the tests:
NVIDIA GeForce FX 5950
ATI Radeon 9800 XT
ATI Radeon 9700 Pro

I'd like to see benchmarks of Painkiller in the upcoming NV40 vs R420 tests...Brickster - Thursday, April 15, 2004 - link
Am I the only one who thinks Nvidia's Nalu is the MOST bone-able cartoon out there?Oy, get the KY!

Did any reviews try and overclock the card? Is it not possible with the test card?DonB - Thursday, April 15, 2004 - link
Would have been better if it had a coax cable TV input + TV tuner. For $500, I would expect a graphic card to include EVERYTHING imaginable.Pete - Thursday, April 15, 2004 - link
Shinei #37,"Speaking of DX9/PS2.0, what about a Max Payne 2 benchmark?"
MP2 doesn't use DX9 effects. The game requires DX9 compatability, but only DX8 compliance for full effects.
Xbit-Labs has a ton of benches of next-gen titles as well, and is worth checking out. NV40 certainly redeems itself in the HL2 leak. :)

Anybody happen to know if it's possible to use a second (old) PSU to run it, you can pick up cheap 235 watt PSU's and would be helped with both extra connectors and power.I'm not sure it won't cause 'sync' problems though as a small difference between the rails of 2 PSU's would cause one to drain the other if the card's connectors aren't decoupled enough from the AGP port.

Agrre with you Trog #59 on the venting. Also with DX9.0c having fp32 as spec., does this mean that FX series cards redeem themselves? (As the earlier DX9 spec was fp24 which was'nt present on the FX gpus causing a juggling act between fp16 and fp32 to match performance and IQ). Still, full fp32 on the FX cards might be too slow.mrprotagonist - Thursday, April 15, 2004 - link
What's with all the cheesy comments before the benchmarks? Anyone?Cygni - Thursday, April 15, 2004 - link
"what mobo and mobo drivers were used? i hear that the nforce2 provides an unfair performance advantage for nvidia"The test was on an Athlon 64 3400+ system, so i doubt it was using an Nforce2. But ya, i agree, the system specs were short. More details are required.

Derek, what was that Monitor you used?Thanks!
