Some of the ideas [from LMA2] have been improved, but it is essentially a new design. It's still multi-partitioned as NV25 was, but the difference is that everything has been built around full-speed operation of 4X FSAA. The horsepower in the ROP [GeForceFX's pixel sub-system that reads and writes pixels, checks z-buffers, does blending, does AA, etc.] and the frame-buffer has been sized accordingly, the caches have been sized accordingly, and the arbitration policies have been designed accordingly, so in that sense it's completely new. It's also running at 2X the clock rate, so the entire design had to be changed to take advantage of DDR-2.
