Well, that’s a nice surprise … AMD have now included Smart Access Memory (Resizable BAR) support on Ryzen 3000 Series. Check out the latest BIOS update from your motherboard manufacturer.
Taken from TPU … AMD in its “Where Gaming Begins Episode 3” online event, announced that it is introducing Smart Access Memory (resizable base address register) support to Ryzen 3000 series “Matisse” processors, based on the “Zen 2” microarchitecture. These exclude the Ryzen 3 3200G and Ryzen 5 3400G. The PCI-SIG innovated feature was, until now, restricted to the Ryzen 5000 series on the AMD platform, although is heavily proliferated across the Intel platform. Resizable BAR enables the CPU to see the graphics card’s entire dedicated memory as one addressable block, rather than through 256-megabyte apertures. For game engines that are able to take advantage of the feature, this could translate to a performance boost of up to 16 percent.
