Smart Memory Access reveals the All-AMD Advantage on Gaming Desktops

Forza Horizon 4 - Resizable Bar On VS Off with AMD's RX 5700 XT

Forza Horizon 4 loves Smart Access Memory. Even at 4K, Smart Access Memory/Resizable BAR deliver us a significant performance boost with AMD's RX 5700 XT. With Forza Horizon 5 coming later this year, the addition of Smart Access Memory to the RX 5000 series will be seen as a great addition for all racing fans. 

With Smart Access Memory enabled, our 1440p results are almost as high as our 1080p results were with Smart Access Memory disabled. Smart Access Memory turns Forza Horizon 4 into a high refresh rate 1440p title on the RX 5700 XT, with average framerates that are over 25 FPS higher. These results show us why high refresh rate 1440p screens are becoming increasingly popular.

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.Quote

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

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. Quote

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).Quote
