Speaking of DRAM, GF100 supports GDDR5 via six 64-bit channels, and the memory clock will likely be in the 4200 MHz range for the highest-end SKUs. The new memory type brings with it unique memory controller considerations, and at the basic level, I/O happens at the device at the same 64-bit granularity as previous-generation hardware.
In terms of texturing, GF100 appears to support the same per-cluster texturing ability as GT200, with eight pixels per clock of address setup and final texel address calculation and up to eight burnable bilerps per clock for filtering, although Nvidia won't talk about it just yet. The texturing rate therefore appears to go up linearly with cluster count, at a peak of 1.6x over a similarly clocked GT200. The texture hardware supports all of D3D11's requirements, of course, including FP32 surface filtering.
