under normal circumstances, AMD RX 7900 XTX The graphics card is not as good as Nvidia’s flagship, GeForce RTX 4090, in terms of pure performance. But there is a way to match the latter in terms of performance – although the price you have to pay may be a little too high for some.
If you remove the RX 7900 XTX’s power limiter, it was able to match the RTX 4090 in the 3DMark10 benchmark with a high clock speed of 3.33GHz. According to the 3DMark Time Spy Extreme score, the graphics card was able to achieve a whopping 18,335 points, which is actually 10% higher than the RTX 4090’s score of 16,654 ( computer gamer documented in its own comment on the latter).
To solve this problem, Reddit user Jedi95 Use a mod to have the VRM controller report incorrect power consumption data to the GPU, thus bypassing AMD’s built-in power limit. While it delivers an impressive leap in performance, overclocking the graphics card to this level requires nearly 700W of power.
Jedi95 details the extensive system needed to keep the card from overheating at such insane power levels, including a high-end custom water cooling setup, 10C coolant temperature, and ample ventilation.
Considering how expensive the average 700W electricity bill is, combined with the high cost of the RT 7900 XTX GPU itself and the cooling setup required to overclock it to this extent, this approach is definitely out of reach for most buyers of.
Good performance but too risky
Not only is the financial cost of using so much power in order to maximize performance a major concern, but the RX 7900 XTX is also in danger of overheating – even with such an extensive cooling solution.
according to Tom’s Hardwarethe flagship graphics card has vapor chamber problem, causing it to reach extremely high hot-spot temperatures exceeding 110C. While this isn’t a widespread problem, based on overclocking expert Der8auer’s (very extensive) testing and reports from other users, it’s still one that needs to be taken very seriously.
Running that much power through a component that wasn’t really built to handle it is already risky, but combine that with the possibility of vapor chamber failure and it’s too dangerous to risk. It’s fascinating that the 7900 XTX has such performance, while at the same time showing us the enormous potential of this card.
However, if you want a graphics card with RTX 4090 performance, you’re better off buying that GPU outright, as it’s optimized for that level of performance out of the box.Sure, the RX 7900 XTX is a lot cheaper, but if you want top-notch performance, you better spend a little more no Might set your PC on fire.
