NVIDIA’s Smart Access Memory Competitor Confirmed For All GeForce RTX 30 Ampere GPUs, Will Work on Both Intel & AMD PCs

It looks like NVIDIA has just affirmed to GamersNexus that they are working on their particular SAM (Smart Access Memory) technologies which are enabled on all GeForce RTX 30 Ampere GPUs in future software updates.

According to the tweet which quotes NVIDIA’s official response to AMD’s SAM (Smart Access Memory) technology, the green team affirmed that resizable BAR is part of the PCI express specifications and NVIDIA’s existing hardware completely supports this functionality. NVIDIA did not see the need to allow this technology feature till now as its competitor (AMD) is already adding aid on its next-gen Radeon RX 6000 series graphics cards based on the RDNA two architecture.

From NVIDIA, re:SAM:”The capability for resizable BAR a part of the PCI Express spec. NVIDIA hardware supports this operation and will enable it upon Ampere GPUs through future software updates. We’ve got it working tirelessly and therefore are seeing similar performance success “

NVIDIA has stated they will be adding support for the attribute through future software upgrades but also it’s going to be compatible with both Intel and AMD CPU based systems. Having support on both AMD and Intel platforms may provide NVIDIA a border since AMD’s solution only works with its Ryzen 5000 lineup and compatible X570 motherboards.

Based on what has been documented, the tech will not be prepared from the introduction of the Radeon RX 6000 series however as it will offer some performance gains on AMD’s front, we can expect gains for NVIDIA’s Ampere GPU structure in a similar ballpark.

The technology won’t need you to put money into a PCIe Gen 4 stage since it will be backed by PCIe Gen 3 also. Based on what we know so far, BAR essentially defines how much discrete GPU memory space can be mapped and today’s PCs are typically confined to 256 MB of mapped memory. AMD asserts that using SAM, they could get all the GPU memory, removing any bottlenecks to allow for quicker performance.

AMD themselves have shown gains of around 11% which can place the competitive advantage to their side in AAA gaming titles over NVIDIA’s GeForce RTX 30 series. We’ve yet to see real results of SAM but together with testimonials planned for next week, we’ll surely get to determine how far performance can be improved with SAM on AMD’s side and what we could expect of comparable technology in NVIDIA’s hands.
