CPU cores may no but on the up, but GPU cores certainly are. Iirc my gtx 670s have 1344 cores each, compared to 4 in my 3770k.

- Symmetry 14y agoIn GPUs "core" means something entirely different from what they do with CPUs. If you counted the 3770k's cores the way GPU manufacturers do, it would have 16 cores. And If you count the GTX 670's cores the way a CPU manufacturer would it would only have a few dozen.
- nivertech 14y agoGPU "core" is equivalent to scalar component of SIMD units like SSE / AVX. You may have 4-8 of them for every hyperthread. So in x86 CPU with 8 core and 2 hyperthreads you may have 8 x 2 x 4 = 64 equivalents of GPU cores. In OpenCL terms it's called a PE (Processing Element). Also what AMD calls a "GPU core" is something smaller, than what NVIDA calls "GPU core".
