We best know said feature today as AMD’s Smart Access Memory, which already offers that small but worthwhile performance increase on compatible Ryzen 5000 processors and Radeon RX 6000 GPUs. Part of the PCIe specification, the function essentially allows a CPU unfettered access to the GPU’s frame buffer to improve performance.
