After checking some data from wikipedia, vendor's specifications and so on, I made this chart above. The chart is about GPU and CPU performance in double precision. While the Intel Core I7 980X (extreme edition) gives us around 110GFLOPS (Source: Tom's Hardware), GPUs such as AMD Radeon 6970 and NVidia C2090 offer more than 660GFLOPS. Obviously these benchmarks represent peak performance under specific conditions for each platform.
