AMD Ryzen 3000 CPUs get go-ahead for performance boosting Smart Access Memory

AMD has today made available Smart Access Memory (SAM) on Ryzen 3000 CPUs. The feature, which allows for more effective communication between CPU and GPU, had previously required both the latest Ryzen 5000-series CPU and RX 6000 GPU in order to function, but is now been transplanted to Zen 2 desktop chips.

Smart Access Memory is a feature that uses a native specification of the PCIe specification, Resizable BAR, to allow for greater and more effective communication between CPU and GPU. It essentially opens up the entire graphics card memory to the CPU, as opposed to how it usually functions—divvying up small (roughly 256MB) chunks at a time.
