MSI said it will support Nvidia’s unsexy-sounding, yet performance-boosting PCIe Resizable BAR feature across many of its AMD and Intel-based motherboards.

Enabling PCIe Resizable BAR is a way to allow the technology underpinning AMD’s new Smart Access Memory feature on Nvidia and Intel hardware, too. Smart Access Memory gives AMD Ryzen 5000 CPUs full access to a Radeon RX 6000-series GPU’s memory, which can deliver varying levels of extra performance, as we found in our Radeon RX 6900 XT testing. Since Smart Access Memory is based on Resizable BAR, activating it on Intel motherboards should offer similar performance benefits, while Nvidia already said Resizable BAR support is coming to GeForce GPUs, which should work with any compatible CPU/motherboard combination.
