ASIC versus FPGA, GPU, and CPU mining
As you can see from a comparison between Table 5.1 and Tables 4.1, 3.1, and 2.1, ASICs hash much faster than any other hardware. The fastest in our list almost reaches up to 5500 GH/s. That is a significant improvement over the other hardware. This is due to the massively optimized nature of application-specific microprocessors.
