I see in some cases huge differences in benchmarks with hyperthreading on compared to with hyperthreading off. I was wondering if anyone can explain this phenominon?
For example Crystal disc mark 4K QD8 thread 8 better than 2300 MB/s without hyperthreading but 1300-1400 MB/s with.
However anvil storage benchmark shows no such huge gain in multithreaded benchmarks & stays around 1700 both with & without hyperthreading on 4K QD16.
These are scores with three Optane Memory drives connected to the PCI-E X16_1 that goes directly to CPU.
Platform is Asus Z390 chipset motherboard with Intel Core I9 9900K CPU.
