Indeed that seems to be more

Disabling software prefetching and switching the autoprefetcher to weak improves
CPU2017 rate and speed benchmarks for both int and fp sets on Falkor.
SPECrate 2017 fp is up 0.38%
SPECspeed 2017 fp is up 0.54%
SPECrate 2017 int is up 3.02%
SPECspeed 2017 int is up 3.16%
