One of the things we always noticed with AMD processor reviews is that the memory latency these days is good but slower than Intel. Currently, we're hitting 67ns, Chinese-based TecLab however posted some photos and screenshots.
Of what they claim to be the Ryzen 7 4700GE socket AM4 processor based on the Renoir architecture, is hitting just 47.6 ns latency when paired with DDR4-4233 dual-channel memory. AMD's 7 nm Renoir APU silicon, would feature eight Zen 2 CPU cores and has merely 25% L3 cache of the 8-core Zen2 assigned in Matisse and older ZEN based processors. It's interesting, that ultra-low latency score. Have a peek:
