PCGH: What do you think: What is the area, current GPUs, throughput processors or however you may call them, are lacking most? Which is the area which should be improved at the forefront?
Bill Dally: Well, they're actually pretty good, so it's hard to faults with them. But there's always room for improvement. But i think it's not about wanting, but about opportunities to make them even better. The areas where there's opportunities to make them even better is mostly in the memory system. I think that we're increasingly becoming limited by memory bandwidth on both the graphics and the compute side. And I think there's an opportunity from the hundreds of processors we're at today to the thousands of cores we're gonna be at in the near future to build more robust memory hierarchies on chip to make better use of the off-chip bandwidth.
this is something he alludes to throughout the discussion. memory bandwidth scaling more slowly than execution resources, and using on-chip caches to mitigate that. presumably an indication of the direction G300 is heading in.
