Wow sweet scores

This is a pretty complicated issue. The term "core" is not used in the same context as a core as we all know it - CPU. They mean that a core can process one thread at a time. In the G80, there are 8 "tiles" of hardware. Each "tile" as two groups of eight "cores." Therefore, there are a total of 128 of these "cores" that can each process a thread. However, each thread that the GPU processes is different and not as complex as regular CPU threads, so it can't be compared apples to apples.



Each green square represents one of these cores.
