But wouldn't something more useful than AVX-512 sell more chips?
Massively parallel floating point workloads on the CPU are a modest niche compared to other ways Intel could have spent engineering effort and chip area, like not ruining the performance of just about everything else with security vulnerabilities.
- shadowgovt 6y agoNobody saw those security vulnerabilities coming. And ironically, they were introduced due to changes that are intended to make the chips faster without explicit parallelization. This goes back to the problem that a modern architecture for a CPU is a massively parallel machine emulating an instruction set design for an embarrassingly serial machine based on best practices from the 1970s.
