>In other words, if a CPU runs at 1 MHz and has two units but where only one can run `fmul`, should you count the CPU as having one or two MFLOPS? I don't think there's enough information to answer that question. For starters, even if the CPU was issued a long sequence of nothing but additions, it's possible that it might spend some fraction of that million cycles waiting on memory. I don't think FLOPS are counted from first principles, I think they're measured empirically using benchmarks. It's possible one benchmark will yield 1.25 MFLOPS and another 1.8 MFLOPS. Split the difference and call it a day.
