My impression has been that for ordinary workloads, RAM speed hasn't mattered much recently. The reason, I assumed, is that modern processors had pushed caches and out-of-order execution quite a distance. This article shows that the Ryzen 5 240g performance is affected by RAM speed. The article doesn't mention number of channels, but that should matter too. <https://www.extremetech.com/computing/263783-evaluating-ddr4-scaling-ryzen-5-2400g-higher-clocks-boost-performance> How come? I suspect that the clue is here: "The CPU-GPU interconnect system uses AMD’s Infinity Fabric as well, and Infinity Fabric’s clock is directly tied to DRAM clock." I wonder if cranking up the DRAM clock, but adding latency cycles, would improve performance without requiring faster RAM.
