Not an expert, but Zen 5 desktop feels like it is being held back by memory bandwidth. Several tests show there is no real benefit in >6000 DRAMs.

- Numerlor 2y agoBandwidth is currently limited by the infinity fabric implementation on consumer AMD CPUs, 6/8 core CPUs with s single CCD top out bandwidth quite early and improvements from higher clocks are minimal even from like 5600, assuming timings are overclocked similarly and beyond basic xmp/expo
- smolder 2y agoSee my top level post for more on this. It's not that there is no benefit to higher frequency memory on AM5, but that there is a penalty introduced above 6000 MT/s which isn't easily outweighed by further raising the memory speed.
