We have already looked at Smart Access Memory technology, which provides full communication between CPU and GPU VM, with all the details. Limited information was provided when this technology was introduced, and the feature was thought to be AMD-specific. Fortunately, this will not be the case, and compatibility will be ensured on both Intel and NVIDIA sides.
NVIDIA recently confirmed that AMD is working on a feature similar to Smart Access Memory, which runs on RX 6000 series graphics cards. The Yesil team also said these capabilities are included in PCIe specifications and are fairly easy to implement. In addition, let’s note that this feature bears the name Resizable BAR (Re-Size BAR).
After the hiatus, AMD stated in an interview with PCWorld that the RX 6000 series GPUs are working with Intel to support Intel’s new CPUs and motherboards. Meanwhile, AMD’s Ryzen group and NVIDIA are working together to make the new feature work with GeForce GPUs.
We do not yet know how much Smart Access Memory technology is customized for AMD components. AMD has taken the first step in this regard, and they may have made some unique optimizations.
AMD also stated in its interview that this feature is not just a toggle switch that you can open. There will be many improvements and optimizations required to achieve good performance gains from the feature. This feature is already available for Ryzen 5000 series processors and RX 6000 series GPUs. In the meantime, in the current case 500 series motherboard is a must underline.
On the Intel side, we do not yet know which processors and motherboards will offer support. Let’s see what the future of this feature and the cross-platform support process will be like.
