> I think Intel makes 18-core CPUs now Xeon Phi is an x86 CPU with many more cores that plugs into a PCI express slot; a sort of halfway between the prevailing GPU and CPU models. They also have 512bit wide SIMD instructions, which should help a lot towards the speed of your vector based computations (AVX2 is 256 bits wide).
