I was just over at Nvnews.com and I see they've scored some NV36 info. User Uttar has gotten some very solid information regarding the NV36 GPU from Nvidia. Made on IBM 0.13u, 82M transistors, 500Mhz core clock

256-bit memory bus, 325Mhz RAW memory (128MB & 256MB versions as the NV31, probably)

Just as the NV35, marketing says it's twice a NV31: thus, half the shader pipes of the NV35 (no FX12, as in the NV35)

Named GeForceFX 5700, taped-out in May, availability dates unknown.
