Today we’re taking a detailed look at how AMD’s Smart Access Memory (SAM) technology influences performance in a wide range of games. All in all, we plan to benchmark 36 games at 1080p, 1440p and 4K. While technically SAM is not an AMD-exclusive technology, they are the first to take advantage of the resizable Base Address Register or resizable BAR, a feature introduced with the PCIe 3.0 spec.
For those of you not yet up to speed, SAM or resizable BAR defines how much of your graphics cards VRAM is to be mapped for access by the CPU.
