Memory latency is one metric out of many.

For memory latency to matter, you need the worst case scenario to play out, which is a miss on all caches.

For cache to be made entirely irrelevant in performance, you'd need a situation where every access is a cache miss.

Yet even a pattern of completely random memory accesses will hit cache once in a while. And even then, a completely random access pattern is absolutely in disconnect with real world applications.

Thus, performance is not determined by memory latency. It is only a factor. And latency has actually improved, like other metrics, when compared to previous generations.

In short, wait for benchmarks. Just some three hours left for NDA lift.

True, and the benchmarks told a very different story for Ryzen 3700 and 3900, that for most of these workloads, the gains from the extra cores far outweigh anything else including tiny RAM timing differences. The tests I saw ran with 3600 speed RAM though, for both.
