Radeon RX 7900 XTX Overclocking, Is 3GHz Possible in Games?

AMD has promised that its RDNA 3 graphics architecture is capable of surpassing the 3GHz mark. A recent study by ComputerBase shows that promise is being kept, though not in all situations.

The Radeon RX 7900 XTX RDNA3 graphics card is quite capable of exceeding this symbolic 3 GHz bar, but not in a gaming context. This conclusion was obtained after overclocking tests conducted on the Radeon RX 7000 RDNA3 series and GeForce RTX 40 “Ada Lovelace” series.

AMD’s flagship model, the Radeon RX 7900 XTX was capable of up to 3455MHz but only under the Blender rendering benchmark, not during heavy video game workloads. The GPU accepted up to 3548MHz with a whopping consumption of around 400W.
