GeForce RTX 3090 Gets 3% Performance Boost From Resizable BAR

A user from the Chiphell forums has evaluated the impact of Resizable BAR on Nvidia’s flagship GeForce RTX 3090. While the results aren’t phenomenal, the extra performance comes free of charge, so we welcome it with open arms.

While Nvidia has pledged to bring Resizable BAR to its entire stack of Ampere graphics cards, only the more recent GeForce RTX 3060 comes with a vBIOS that’s primed for the feature. Other Ampere offerings will need an updated vBIOS to enjoy the same benefits. Nvidia and its partners are expected to release vBIOS updates for their corresponding graphics card tomorrow. However, Galax and Gainward have already started deploying the new updates, which has enabled the Chiphell forum user to test the Resizable BAR feature ahead of everyone else.
