Is AMD R9 390X faster than 390 at the same core/memory frequency?
It is.
MSI 390 @1135/1500 gives 415 H/s
MSI 390X @same gives 425 H/s
Both stock bios, wattage not measured.
Thanks a lot.
So it seems that 390X is just 2% faster but it has 10% more cores.
Can you measure the power with GPUZ. It is not accurate, but it gives us some indication.
