An AMD Radeon RX 7900 XTX graphics card is capable of trading blows with NVIDIA GeForce RTX 4090, as overclocker jedi95 found out. With its power limits unlocked, the RX 7900 XTX was found reaching engine clocks as high as 3.46 GHz, significantly beyond the "architected for 3.00 GHz" claim AMD made in its product unveil last Fall. At these frequencies, the RX 7900 XTX is found to trade blows with the RTX 4090, a segment above its current segment rival, the RTX 4080.

Squeezing 3.46 GHz out of the RX 7900 XTX is no child's play, jedi95 used an Elmor EVC2SE module for volt-modding an ASUS TUF Gaming RX 7900 XTX, essentially removing its power-limit altogether. He then supplemented the card's power supply, so it could draw as much as 708 W (peak), to hold its nearly 1 GHz overclock. A surprising aspect of this feat is that an exotic cooling solution, such as liquid-nitrogen evaporator, wasn't used. A full-coverage water block and DIY liquid cooling did the job. The feat drops a major hint at how AMD could design the upcoming Radeon RX 7950 XTX despite having maxed out the "Navi 31" silicon with the RX 7900 XTX. The company could re-architect the power-supply design to significantly increase power limits, and possibly even get the GPU to boost to around the 3 GHz-mark.
