BIOS Flashing AMD’s RX 5700 can generate some hefty performance gains

AMD’s graphics cards have responded well to BIOS tweaking, finding its origins before the release of AMD’s GCN architecture. Over time Radeon users have been able to unlock more GPU cores, overcome power limits and, in the case of early RX 480 cards, unlock an extra 4GB of VRAM. 

Wccftech’s Keith May has asked this question. What happens when you place an RX 5700 XT’s BIOS into a Radeon RX 5700? The answer, as it turns out, is increased clock speeds, higher power limits and increased overclocking potential. Not bad for a BIOS flash. 

The reason for this performance boost is simple. The Radeon RX 5700 XT’s BIOS files increase the RX 5700’s power limits and increase the GPU’s base and boost clock speeds. Beyond that, the GPU’s increased power headroom also offers up additional overclocking potential, enabling the RX 5700 to deliver RX 5700 XT-like performance levels. Not bad, especially when the RX 5700 XT can achieve performance levels that can sometimes rival a Geforce RTX 2070 Super. 
   
We will not go deeply into the methodology behind BIOS flashing here, but leave that the Keith article here. Below is one of the many performance charts that have been created to showcase the benefits of BIOS flashing AMD’s reference RX 5700 graphics card.
