Hmmm, interesting. Another problem is memory latency. Actual throughput is usually about 10% of advertised throughput because programmers and compilers can't give the processor useful work to do for most of the clock cycles. My source for this 10% figure is from some slides from Ulrich Drepper, but I don't have time to find them right now.
