BIOS-modded AMD Radeon RX 9070 with RX 9070 XT firmware is 15-20% faster than stock

Enthusiasts delving into the overclocking potential of AMD's latest Radeon RX 9070 series found something we haven't seen for some time. In a throwback to the days of widespread BIOS modding, it appears that some Radeon RX 9070 non-XT GPUs can be flashed with the BIOS from their XT counterparts, increasing power limits and unlocking more performance.

As PC Games Hardware (via VideoCardz) reported, this BIOS flashing effectively unlocks higher clock speeds and a greater TBP. However, it's crucial to understand that this modification does not alter the core count or memory specifications, which are currently identical across both SKUs.

By modding the BIOS of these cards, users can overclock these cards more aggressively. One modder claims that the flashed card achieves performance levels comparable to or exceeding the reference RX 9070 XT. The performance uplift is substantial, with users reporting gains of 15-20% compared to the stock RX 9070 non-XT.

While the performance gains are enticing, there are potential drawbacks. Reports indicate that ULPS (Ultra Low Power State) mode may become dysfunctional, and some users have experienced system freezes. Furthermore, there are hardware considerations, such as the power delivery system, which might not be adequate for the extra that will go through it. If you want to go through this route, ensure that your card can handle it.

KitGuru says: If you had an RX 9070, would you mod it with the RX 9070 XT BIOS?
