A few weeks ago, AMD announced the initial SKUs of the RX 6000 series of graphics cards. Based on the new RDNA 2 architecture, these graphics cards support hardware-accelerated ray-tracing, which has become an industry norm at this point. Another compelling feature that AMD boasted during the presentation was its Smart Access Memory. It allows compatible Ryzen processors to access the whole GPU memory rather than using it in chunks, which results in a huge performance improvement. It turned out it was not an AMD feature rather a feature enabled by Direct X12 in Windows, and AMD had adopted it.
It was soon announced that the RTX 3000 series graphics cards are also compatible with the feature commonly named ‘Re-Size BAR‘. Since Nvidia is yet to announce something in the competition, its AIB partners such as MSI and ASUS have already announced that they can implement the feature.
MSI has already released the new drivers for the AMD-400 and AMD-500 series of motherboards. The new update has two important features. Firstly, it optimizes the AMD Curve optimizer function, which will help in overclocking. All AMD Ryzen processors are unlocked, so the update will enhance the overclocking experience for the consumer.
Secondly, it enables Re-Size Bar support for the Nvidia Graphics cards in addition to the AMD graphics cards, which are already compatible. It is not sure whether the functionality will only available for the Intel/AMD or both CPUs. Only the following motherboards are receiving the BIOS update. The rest will be updated by the end of January 2021.
