An AMD-based system's most important performance pairing lies in the CPU and system RAM, as a million articles written ever since the introduction of AMD's first generation Ryzen CPUs have shown (remember the races for Samsung B-die based memory?). There are even tools that allow you to eke out the most performance out of your AMD system via fine memory overclocking and timings adjustment , which just goes to show the importance the enthusiast community derives from such tiny details that maximize your AMD Zen-based CPU performance. Now, notorious leaker @momomo_us has seemingly confirmed that AMD has worked wonders on its memory controller, achieving a base JEDEC 3200 MHz specification - up from the previously officially supported DDR4-2666 speeds in the first-gen Ryzen (updated to DDR4-2933 speeds on the 12 nm update).The importance of system memory for AMD lies in the fact that the CPU's CCXs use the memory bus as a way to calculate their Infinity Fabric speeds, which allows for inter-CCX communication - higher memory data rates thus equal higher CPU performance as a whole. The increase in the base JEDEC specification support means that AMD have worked on adding a little grunt to their memory controller which should help improve IPC due to increased Infinity Fabric capabilities. momomo_us also confirmed at least up to 4400 MHz OC "official" support from AMD, a far cry from current AMD Zen silicon - even in its 12 nm iteration. Let's wait to see if the current salty 5000+ MHz DDR4 speeds are indeed possible, come the product's launch.
