Of course I understand it.
And as that 12 instruction popcount implementation is almost totally serial, on a typical 3 or 4 wide modern OoO x86 CPU you can do 3 or 4 popcount calculations in those 14 clock cycles (or maybe 16 or something), so the ratio remains basically the same no matter whether you're talking about latency or throughput. As I SAID in my previous post.
