Originally posted by coder View PostDo you have any sources on this (other than the ones in your post, which are unrelated to PSF)?Zen 3's Predictive Store Forwarding aims to enhance performance by trying to predict dependencies between loads and stores. PSF can speculatively execute instructions based on what it thinks the result of the load will be and while the predictions should be largely accurate, there is the possibility of incorrect CPU speculation.Phoronix, Linux Hardware Reviews, Linux hardware benchmarks, Linux server benchmarks, Linux benchmarking, Desktop Linux, Linux performance, Open Source graphics, Linux How To, Ubuntu benchmarks, Ubuntu hardware, Phoronix Test Suite
