Normally you are limited to a maximum block of 256MB. So, Resize BAR compatible processors can get full access to your graphics card memory. As such, at the Radeon 6000 series release, they marketed their implementation labeled "SAM," initially offering great differences in some, but certainly not the majority of games. However, that old resize Bar feature can now make use of the entire graphics card memory as opposed to a small chunk of it.ĪMD noticed that it could help a bunch of games in performance, and they do love stuff that is free to perform some marketing on stuff and create hype/virals. Basically, it was invented to help out integrated graphics processors perform a bit better. Resizable BAR actually is nothing new the processor can access the graphics card memory via the PCIe bus, which has been included in the PCIe specifications for a long time. That means 414 test runs for this article + added frame time tests, which was a daunting and time-consuming task, really.
That meant retesting nine graphics cards over a suite of software considering we can no longer use older benchmark results, we had to perform an A-B test, meaning the same setup configured with the same drivers and then Resizeable BAR on and off.
On its end, NVIDIA, a few weeks or so ago, also started offering Resizable BAR compatible BIOSes and driver support for the RTX 3060, 3060 Ti, 3070, 3080, and 3090. However, with the latest drivers and AGESA BIOS updates, that gap narrowed down quite a bit, raising the question if early SAM/Resize BAR results actually have been affected by something other than SAM. 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.

I've researched and learned that El Capitan has a few issued recognizing usb ports on the specific motherbaord that I have.
This is my first hackintosh build and i was wondering what is the most user friendly version of OSX to install (10.9, 10.10, or 10.11) with the hardware that i am using.
