Smart Access Memory on RX 5000 Series Tested - A Free Performance Boost!

AMD's early RDNA graphics cards have just gotten a major performance boost.

Read more about AMD's SAM support for their RX 5000 series GPUs.

For some reason the conclusion page is titled "Watch Dogs Legion - Resizable Bar On VS Off with AMD's RX 5700 XT".

Nice to see that SAM no longer seems to hurt performance. I wonder if it still does on some games, or if AMD fixed it such that if it doesn't help then at least it doesn't hurt.

Might be the conclusion page was missing entirely. Looks correct now.

I corrected it last night, but it was late and I forgot to reply here to confirm that it was now fixed.

Thanks for the spot ET3D.

I only thought of it now, because Hardware Unboxed discussed SAM (and not using it) in the recent Q&A, but any chance you could test Apex Legends or Serious Sam 4 (Vulkan)? Both games lost quite a bit of performance with SAM enabled when tested by HUB in January. I wonder if AMD fixed the performance regressions since then or if they're still there. That would affect if SAM is worth turning on by default (and using it in reviews).
