> the Virtex-7 (a VERY EXPENSIVE fpga) can hold 1000 very simple 32 bit cores.... but a top end NVIDIA GPU has 2688 CUDA cores. But the point of the FPGA is to not build cores inside it; the OP article is just an exercise. Application specific logic built with FPGA might be much more efficient than generic CUDA cores. Also, it is a given that an ASIC will be more power efficient than an FPGA, but the FPGA will be generic and hence more money efficient.
