Now that Nvidia has lifted the NDA on some of the official details surrounding its upcoming Fermi-based GF100 GPU, the Web is chock full of updated info, teaser videos, and even a Far Cry 2 benchmark.
To sum it up, GF100 has 512 CUDA processors, 16 geometry units, 4 raster units, 64 texture units, and 48 ROP engines. Like ATI's latest cards, GF100 comes with full DirectX 11 support. But unique to Fermi is a pretty big 768KB L2 cache buffer shared between four Graphics Processing Clusters.
In one video, Fermi is shown running Far Cry 2 at 1920x1200 with 4XAA and Ultra High settings. Framerates never dropped below 65, compared to under 40 in another system equipped with what appears to be an ATI HD 5870 videocard.
