Initially, the SAM / Resize BAR / rBAR made a substantial difference for some games. In short, our benchmark results for the AMD platform needed to be retested, and as such, we figured to test a good chunk of games with the new PCIe Resizable BAR feature with the Radeon RX 6700 XT, 6800, 6800 XT, and 6900 XT. ![]() In contrast, CyberPunk 2077 brought non-SAM results close to SAM-enabled results (after the most recent update). The recent Hitman 3 update, for example, shows a negative performance effect on AMD Radeon performance. As such, a re-test of many titles was due for an update. AMD recently introduced a new series of motherboard AGESA BIOSes, and the late march drivers can have a positive effect on performance. ![]() Here at Guru3D, our test suite is based on games tested on both Intel and AMD platforms. We test and benchmark this feature on all compatible graphics cards and will try and show you if it is worth the hassle of getting Resize Bar compatible. And easy op[tion that possibly can bring extra performance. Resizable BAR tested: Nvidia GeForce RTX 3000 and Radeon RX 6000Ī couple of months ago, AMD introduced SAM, aka Smart Access memory, which really is PCI-Express Resizable BAR.
