>it's the difference between a sandy bridge (2011) and a skylake (2016)
also a big IPC difference between those two

9800X3D has a BIOS option that messes with memory latency, "Zen 5 Gaming Optimizations"
all those tests need to be done on the same BIOS version for zen 5

i've seen people get the same or better memory latency as me on 5800X3Ds
this 5800X kinda sucks ass, can't do 1900 FCLK, can't do more than -10 CO, can't do more than 4.9 GHz
but i'm sure there's a few games where non-X3D is superior

the real lesson is that you should always tune your hardware
