NVIDIA NV40 Information

Posted on Monday, September 08 2003 @ 11:27:25 CEST by

NFI has posted a chunk of information about the NV40 and the Detonator 50 drivers :

In order of decreasing reliability:
  • Supports FP32, FP16 and FX16 natively. Whether there is any performance difference between FP16 and FX16 is unknown, and whether there are any truly non-FP32 units is also unknown.
  • 175M transistors, 600Mhz core clock, 1.5Ghz effective GDDR2 ( Samples already shipped to nV - 16 memory chips per board )
  • Not taped-out yet, or if it did, tape-out failed. To tape-out sometime this month.
  • 8 pipelines, Speculation: probably 8x2 and no 16 zixel trick ( not worth it with 4x+ AA, which is really a minimum with 48GB/s of bandwidth ) - Maybe such a bypass path for low-end models ( NV42/NV43 )

    This means Christmas avaibility has IMO become absolutely out of the question. Best we can hope is for-developer documents for Comdex, or around then. And that's not a certainty.

    Finally, Det50s probably are for the 15th, but I doubt that will mean public download - more like previews for AquaMark 3. That's the best case scenario - it might also be launched with the NV36 at Computex ( September 22-26 )
