![]() Zen+, Ryzen second generation, is great but didnt perform as well against Intel chips. More information about our games testing system is available here. Zen 2 has overall better performance at a very similar price. This feature allows AMD's RX 6800 series to utilise Smart Access Memory, giving users more system performance in some scenarios. Below is a screenshot of the BIOS of our X570 Crosshair VIII Formula motherboard, where we can now enable an option called "ReSize BAR" with compatible processors. That said, it may take a while for PCIe bandwidth to become a limiting factor with some games.Įnabling Resizable Bar on an ASUS motherboard In this article, we will be using our standard GPU/Game test system, which uses a Ryzen 9 3950X processor with Precision Boost enabled, a Crosshair VIII Formula motherboard with BIOS 3003, 16GB of Corsair 3600MHz DDR4 memory and a Radeon RX 6800 graphics card. This technology will allow CPUs and graphics cards to benefit from the bandwidth offered through PCIe 4.0, as increased GPU memory access will undoubtedly result in increased bandwidth utilisation. Thanks to this access, AMD users can benefit from increased game performance within existing titles, and developers can exploit this access for further performance gains with future game releases. With AMD's Smart Memory Access technology, AMD is granting their CPUs access to the entirety of the RX 6000 series' frame buffer. Since then, GPU memory sizes have exploded, with AMD's Radeon high-end RX 6000 series of graphics cards featuring a whopping 16GB of GDDR6 memory. What is Smart Access Memory? Before now, CPUs had access to 256MB of GPU memory, an allocation size which made a lot of sense in the early 2000s. In this overview, we will be testing Smart Access Memory using our Ryzen 9 3950X Zen 2 processor across a large selection of games to judge the performance impact of the feature. The Evolution of Zen AMD Zen 2 CPU-based system scored an estimated 15 higher than previous generation AMD Zen based system using estimated SPECint. ![]() With a Radeon RX 6000 series graphics card and an motherboard/CPU combo which supports the optional PCIe "Resizable BAR" feature, gamers can see significant uplifts in game performance in some titles, effectively giving PC users a free performance upgrade. Our GPU test system, which uses an ASUS X570 Crosshair VIII Formula, now has a BIOS update which adds support for a feature called "Resizable BAR", the cornerstone of AMD's Smart Access Memory (SAM) feature, and it would be rude not to test it out on our Ryzen 9 3950X. For performance desktop and mobile computing, Zen is branded as Athlon, Ryzen 3, Ryzen 5, Ryzen 7, Ryzen 9, and Ryzen Threadripper processors. The AMD Zen 2 Processor IEEE Journals & Magazine IEEE Xplore The AMD Zen 2 Processor Abstract: The Zen 2 processor is designed to meet the needs of diverse markets spanning server, desktop, mobile, and workstation. AMD's Smart Access Memory technology is a major innovation, and it is now available to users of Zen 2 processors, assuming that your motherboard supports it. Zen 2 is AMD 's successor to Zen+, and is a 7 nm process microarchitecture for mainstream mobile, desktops, workstations, and servers.
