Memory Latency does seem to be a problem, Ryzen 7 1800X with DDR4 3200 CL16
L2, L3 and Mem all 2x worse than Skylake
EDIT: on the other hand L2, L3 bandwith is 2x higher (and memory BW a bit better)
It is reporting info for all cores summed, so you need to divide by core counts to arrive to "per core" bw for L1/L2 caches. AMD stuff is inline with what they reported and what was leaked and is great for company with a history of weak caches.
Memory latency hurts the eyes tho, even accounting for extra 10ns for slower L3, 73ns is massive compared to ~50ns for Intel.
