I was wondering what would be the future of GPU computing in 5 or 10 years down the road. How many cores can we expect to get for a regular card in the future? Do we have a linear growth or sub/supra-linear growth in regards to the number of cores/card. Are there any known limits to that similar to the clocking speed for CPU’s?
moores law probably applies here pretty well, we are approaching the limits of silicone but there will be significant breakthroughs in fabbing techniques that allow more transistors to be in one chip and take up less space, produce less heat and use less power.
ultimately nobody can predict the future but you can rest assured that graphics cards in 10 years time will be mind blowing.
Bill Dally, NVIDIA’s Chief Scientist and VP of Research, gave a talk on this subject recently. The video is available on iTunes U .
