AMD 6000 series GPUS and Ryzen 5000 CPUS

Supposedly pairing them together makes it run "fast for games" but I can't seem to find any kind of benchmarks for it I'm curious if anyone knows anything about it only found an article about it here.

SAM is amds implementation of rBAR, which has been part of the pcie spec since pcie 3.0. rBAR is available on most ryzen and intel 9th gen and up systems iirc, and should work fine.

Gotcha, so there's no real benefit of pairing AMD with AMD vs Nvidia with AMD or Intel and vice versa and what nots.

I do find it odd that there's no real info comparing the 2 (AMD's SMA, Nvidia's Rebar)

On desktop, not really. There is tighter integration on laptops.

It's technically the same thing. The technology is called rBAR and has been around for some time, but basically no one bothered to allow users to enable it. AMD was the first one to do so, and they dubbed it "SAM" as a marketing name. Nvidia quickly followed, but obviously they can't use the same name as AMD does.

it's understandable but would be neat to see if there is any difference at all is one better than the other or is it just that same thing different name, i can guess and say there is probably zero difference.

Same thing, different name. But based on some benchmarks I've seen there are performance differences between the two. Probably down to how the driver does things or maybe also differences in the code paths of individual games for AMD/Nvidia.

 

~edit: Or, I should say there is a differences in performance gains with it enabled/disabled. In some games AMD gains more in some games Nvidia gains more etc.

NVIDIA's ReBAR implementation is garbage. At best the performance is the same, at worst it's even significantly worse. Where with AMD's SAM, at worst the performance is the same and at best you gain even up to 15% or 20% or something. I don't really remember SAM ever going negative. With NVIDIA, almost always. And I have X570 and RTX 3080, both with ReBAR supported BIOS and latest drivers on Win11 that should support all this.

I had a 5600x paired with a 6700 xt for a while and saw a few frames improvement at 1440p. But not major enough to be a strong "oh boy!" feature. Still, it was free and easy to turn it on, so I used it!
