GT300 to feature 512-bit interface

May 17th, 2009 Posted in GPUs

Over the past six months, we heard many rumors about the upcoming nVidia GT300 GPU. The last information surfaced on the web reveals that GT300 might feature a 512bit wide GDDR5 memory interface. If this is true, this would mean that nVidia has a playing field of eight 32bit memory controllers connecting to multiple 32 core clusters for a total of 512 cores. If the GT300 chip ends up connected to quad data rate memory at 1000MHz we'll have a memory bandwidth of 256GB/s per single GPU. At least from these little information leaks, we're looking at one beast of a GPU. GT300 is expected to be released in Q4 2009.
