In section http://tvm.d2l.ai/chapter_cpu_schedules/arch.html#performance, the measured GFLOPS is 774.949674567942 and the peak performance is 640. Why is the measured GFLOPS larger than the peak performance? And it says "As can be seen, the measured GFLOPS is close to the peak performance (~90% of peak)." which I don't know how ~90% of peak calculated.
