Smart Access Memory on Zen 2 CPUs - The Power of Resizable Bar!

Forza Horizon 4 - Resizable Bar On VS Off

Forza Horizon 4 is practically the poster child of AMD's Smart Access Memory technology. The game is one of the best looking titles on Xbox and Playground Games is one of the most talented studios that the Xbox brand has to offer. If there is a studio that can push the limits of hardware, it's Playground games, and Smart Access Memory/Resizable BAR support can make Forza Horizon's framerates soar. 
 
While 1st percentile framerates stay mostly constant at 1080p (likely due to CPU performance limits), average and 95th percentile framerates see notable increases. At 1440p, Smart Access Memory enables performance levels that are better than our 1080p results with Smart Access Memory disabled, showcasing how much the technology can speed up the game's performance. It's results like these that make Resizable BAR a must-enable feature for all Radeon RX 6000 series users. 

At 4K, Smart Access Memory is enough to keep Forza Horizon 4 at 120+ FPS performance levels under most circumstances, which is a big deal for users of today's HDMI 2.1 compatible 4K TVs and monitors. Forza Horizon 4 shows that Smart Access Memory was a worthy investment for AMD. It will be interesting to see how future games are impacted by the technology.

The results in Assassins Creed and Forza are pretty impressive for something as simple as a bios update.Quote

Yeah, it is crazy how much extra performance the feature brings to some games. It will be interesting how games utilise this feature in the future, especially when Nvidia adopts a form of it.Quote

Some X470 and B450 boards do, I wouldn't expect the full functionality though as the boards are quite literally missing the hardware needed for full PCI-E 4 support.
