NVIDIA is soon getting “Smart Access Memory” feature

NVIDIA has recently confirmed to GamersNexus that they are working on their own SAM or Smart Memory Access technology which will be enabled for all GeForce RTX 30 Ampere GPUs in future software updates.

A tweet which quoted NVIDIA’s official response to the SAM technology of AMD, the green team confirmed that resizable BAR is a part of PCI express specifications and the existing hardware of NVIDIA fully supports this function. NVIDIA has not seen the need to enable this technology feature till now because its competitor is already adding support on its next-gen Radeon RX 6000 series graphics cards based on RDNA 2 architecture.

NVIDIA said that they would be adding support for the feature through software updates in the future but it will be compatible with both Intel and AMD CPU based systems. Support on AMD and Intel platforms might offer NVIDIA an edge since the solution of AMD only works with Ryzen 5000 lineup and compatible X570 motherboards.

Based on various reports, the technology will not be ready for launch by the time when Radeon RX 6000 series will be released but since it offers some performance gains on AMD’s front, gains can be expected for NVIDIA’s Ampere GPU architecture in a similar ballpark.

The technology will not need users to invest on a PCIe Gen 4 platform because it will be supported by PCIe Gen 3 as well. Based on what is known till now, BAR defines how much discrete GPU memory space can be mapped and today’s PCs are normally limited to 256 MB of snapped memory. AMD claims that through SAM, they can access all of the GPU memory and removing any bottlenecks to allow for faster performance.

AMD has shown gains of around 11% that can put up the competitive advantage to their side in AAA gaming titles over NVIDIA’s GeForce RTX 30 series. Still we have to see the actual results of SAM with reviews next week and we will surely get to see how far the performance can be improved with SAM on AMD’s side and what can be expected from a similar technology in the hands of NVIDIA.
