Thus, the average time to add two 10-digit numbers is
40 cycles, or about a
2.2 kHz add rate. Adding two 20-digit numbers is 70 cycles, or an add rate
of 1.2 kHz. Compare that to a modern superscalar microprocessor with a peak
add rate of two 64-bit add instructions per cycle at 3-GigaHertz, or an add
rate of 6 Ghz; the modern microprocessor is 6,000,000,000 / 1,000 =
6,000,000 times faster!
Most (all?) Bitcoin miners these days use either badass GPUs or
dedicated Bitcoin hardware, so the number is quite a bit larger.
