OPTICXCESS — AMD Smart Access Memory Will be also introduced by NVIDIA

AMD Smart Access Memory (SAM) is arguably a special technology for the red team. And Nvidia is rumored to offer technology similar to Smart Access Memory.

AMD Smart Access Memory

As we know, Smart Access Memory is an exclusive feature that is only served through a triple combo between AMD Ryzen ™ 5000 Series processors, AMD B550 and X570 motherboards, and Radeon ™ RX 6000 Series graphics cards.

The manufacturers themselves claim that this technology will give AMD Ryzen ™ series processors greater access to high-speed GDDR6 graphics memory, speed up CPU processing and provide up to 13 percent performance boost in certain games when combined with the latest Rage Mode one-click overclocking settings.

In essence, this technology aims to solve the problem where the CPU can only access a small portion of the GPU VRAM at once. Naturally, By making use of the PCIe bandwidth, SAM extends its data channel and uses all the speeds offered by a PCIe connection.

Well, the latest news from Gamers Nexus which reveals that Nvidia itself will have technology similar to what AMD has to offer. “The scalability of the BAR is part of the PCI Express specification. NVIDIA hardware supports this functionality and will enable it on Ampere GPUs via a future software update.

“We’ve made it work internally and seen similar performance results.” And indeed, it has been part of the PCIe specification since 2008. This document dated 2008 says that “This optional ECN adds the ability for Functions with BAR to report various options for the size of their memory-mapped resource that will operate properly. Also added is the ability of the software to program sizes to configure BAR. “Any PCIe compatible device can activate it with a driver update via software”.

The current AMD SAM implementation requires a Ryzen 5000 series CPU, 500 series motherboard chipset, and the latest Radeon RX 6000 series GPU. NVIDIA implementations can cover a wide range of hardware, including Intel and AMD CPUs and their respective platforms. That means even the PCIe 3.0 standard will get less attention, as Intel’s desktop platforms are currently limited to PCIe 3.0. NVIDIA will use the driver update to activate the feature, however, it may take some time for it to arrive as the feature is still being developed.
