Там проблема в том что связь с кэшом зависит от частоты оперативной памяти
With Zen, and to a lesser extent Zen+, AMD's DDR4 memory latency numbers were notably larger than Intel's competing processors, with AMD's caches presenting similar issues. With Zen 2, AMD opted to mitigate these problems, both by working to decrease memory latencies, and by doubling Zen 2's L3 cache sizes to decrease their processor's reliance on DRAM for critical data.
In their latest presentation, AMD has called their revamped L3 Cache "GameCache", noting how their doubling of L3 cache sizes their reductions in "effective memory latency" have had a considerable impact on their processor's gaming performance.
In the slide below, AMD notes that their L3 cache changes have a larger impact than moving from 2667MHz DDR4 memory to 3600MHz speeds. Those who are familiar with AMD's original Zen processors will know that DDR4 memory speed has a notable impact on game performance, a factor that makes the performance impact of AMD Zen 2 cache changes all the more astounding.
