Error. Best you update your knowledge base as the RX 5700 supports SAM. Each game will perform differently as this has been covered previously in depth by other content providers. Please note that with newer drivers even a RX 5700 with RSR will upscale to 4k on a capable display. So with a game being rendered at 4k, one can turn down if not run off post processing that will increase the frames per second also lower the GPU temperature. ✌
Interesting that without explicitely searching for it, it seems like only the RX 6000 series is supported. You are absolutely right, they patched it and didn't update their website. Most third party sites also didn't besides maybe a seperate blogpost.
@@MichaelNROH No problem, though it was covered in reddit and by IGN, overclock3d and guru3d in September of 2021. Those that have a RX 5000 series GPU were probably delighted when it was noted in the driver updates, not to exclude Ryzen 3000 series owners. Keeping in mind that the RX 5000 series was released back in 2019 July 7th, and that the main reference pages will be updated showing the most current products.

Nice vid! I was wondering if this resizable bar really improves a lot or not and hey, just in case if you didn't know, Shadow of the Tomb Raider pushes really hard on a single core if you run it at DirectX 11 mode. I noticed that you're using the wine version and GPU bound is at 32~37%, which means that your CPU is being a bottleneck due to the single-core overhead caused by the game. I also have a AMD GPU (Radeon RX 5500XT 8GB) and I suggest you to change to DirectX 12 mode and disable shadows (because that's the reason why this game crashes at DirectX 12 mode on Linux, seems to be a Vulkan feature missing on AMD GPUs that is required to draw shadows at DX12) Doing that you will notice that your FPS will be way higher and you will get more accurate results about Resizable BAR and etc!
Mh, I just assumed that DX12 gives lower performance because it was very bad on my old NVIDIA GPU. Like, really bad, not just old Gen Vulkan bad, but thanks for the tip.
@@MichaelNROH OOF, nvidia drivers on linux are unfortunaly very bad on some games and APIs 😅 At least in order to run Davinci Resolve and OBS with hardware acceleration is easier than AMD
Even though I got a 11th Gen Intel CPU, I can't seem to find it in my laptop's UEFI options. Maybe I'll have to try getting the BIOS flash on the weekend. Not sure, cause fwupd doesn't show my device in the list at all.
Laptops have a very locked down UEFI, so I guess there is no way to enable it manually (it might be enabled if it supports it) unless you want to go through the risk of flashing a custom one.

Depending on the games you play, an RX 6800 or XT might be too powerful for your CPU. Basically it can't run as fast is it could when the CPU can't keep up. I'm also not sure if SAM (rebar on AMD) is supported with this CPU model at all. I think it's Zen3 an above, so 5000+

Resize-Bar probably only appears when you enable Above 4G Decoding. It's invisible by default on my mainboard as well. The thing is, that both options are essentially the same thing and it depends, how the operating system and driver handles it. Just enabling Above 4G Decoding without resize-bar did change absolutely nothing for me. Probably because the AMD driver didn't use it, but Windows itself could.

@@MichaelNROH thank you.. yes its enabled by default on my laptop.. also i deep searched a little bit i found that if support It takes part from the the VRam of the GPU..

It is supported in some ways, but not advertised and I couldn't find reliable sources. It could work with a CPU, from the NVIDIA hardware specs but I can't promise it.
That's not the reason though, since faster streaming of Assets would still be beneficial for the CPU. CS:GO just does not stream many (or any) assets by default. Even the setting texture streaming does not add much to it.

Asus Prime B450-a mobo also allows it.
SAM is definitely by far better than just ResBar...
intel 10 gen also i have it and it works
fun fact amd never mentions Intel cpus for rebar support, but you can use rebar with intel cpu and amd gpu.
Yes, they are not mentioning once, which CPUs are compatible themselves

Thanks a lot! I was wondering why my intel cpu didn’t work and didn’t find it in the Bios. Who knew it was that hidden in advance.
Pretty nice feature. I have it enabled with 9100f.
Fun fac it even wrks on 8th gen and 9thgen Intel, idk about 6th and 7th havent tested it yet.
Do productivity software (or any software in general) benefit from enabling this? Or is it purely gaming-oriented?
Technically, every software who frequently needs to access huge amounts of VRAM. Crypto-Miners were really into it

It is supported in some ways, but not advertised and I couldn't find reliable sources. It could work with a CPU, from the NVIDIA hardware specs but I can't promise it.
I can't say with enough confidence. ReBAR is supported if both CPU and GPU (also your motherboard) have PCIe 4.0.

Save changes..
CS:GO doesn't show significant improvement if you enable ReBAR due to the game is prone to be CPU bound.
That's not the reason though, since faster streaming of Assets would still be beneficial for the CPU.
CS:GO just does not stream many (or any) assets by default. Even the setting texture streaming does not add much to it.
