The Radeon RX 7900 XTX was modified by the Reddit user name Jedi95 to run without a power limit. This experiment was done in order to demonstrate just how fast the RDNA3 card is when unlocked. With the help of a custom water cooling kit, the user was able to achieve RTX 4090-like performance in 3DMark.
When unlocked, the Radon RX 7900 XTX can reach a boost clock of 3.3 GHz. However, the only downside to this mod is the power draw since the graphics card can consume nearly 700W.
The modified Radeon RX 7900 XTX was able to hit a score of 18,335 points in 3DMark Time Spy Extreme. Compared to that, the GeForce RTX 4090 scored 16,654 points, making it 10% slower than the AMD flagship.
With an impressive score like that, the Radeon RX 7900 XTX can directly compete with the GeForce RTX 4090. However, it is clearly not feasible to run daily and is only suitable for demonstration purposes. Additionally, the 3DMark score is not always representative of the actual gaming performance of a graphics card.
The user used a shunt-like mod on the Radeon RX 7900 XTX. This mod helps bypass the VRM controller by reporting false power consumption figures. Furthermore, the mod used by Jedi95 is also better than the traditional shunt mod, which lets him have control over the power reporting via software.
Running hardware beyond its limits is impressive for the Radeon RX 7900 XTX. It lets us see what RDNA3 can do once all its limitations are removed. However, running a card above its power target and such a high power draw is not recommended.
AMD also went with a refresh of its RDNA2 series cards before the launch of RDNA3, coming up with cards like the Radon RX 6650XT, RX 6750XT, and more. So there might also be a Radeon RX 7950 XTX soon, with increased power limits.
