You dont understand the application sorry. For this particular application, as being discussed, the competition is FPGAs and other exotics, not CPUs, and yes, latecy of interest is in uSec. GPUs were of interest a while ago, now not so much.

You are also forgetting that latency adds.. moving data extra steps is bad, and FPGA and similar exotica have pretty much removed such steps now.

however, the initial moronic post has zero understanding of the situation in so many ways, that its hardly even worth bothering about, really.
