Does it mean the GPU becomes a CPU (microprocessor, or central processing unit)?
BD: Both of those terms will blur. Both of the cores are processing cores. They both execute instructions. A CPU today is optimized for single thread performance. That’s becoming less important all of the time. It runs the legacy code (i.e., Windows). People are writing more code that takes advantage of parallel processing in a throughput processor. The other reason is single-thread performance isn’t scaling. Moore’s Law says we double the number of transistors on a chip every couple of years. It gives us more transistors. Chip architects take more transistors and deliver more performance. And then application writers take more performance and deliver more value to the user. That food chain is broken on the latency processor side. We get more transistors over time, but they don’t make a single-thread processor go any faster. CPU makers respond to this by putting a lot of cores on a chip to try to take advantage of throughput. If you’re going to take advantage of throughput, it’s far mo
