The Radeon RX 7900 XTX and overclocking, is 3 GHz possible in gaming?

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

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

AMD’s flagship model, the Radeon RX 7900 XTX was able to withstand up to 3455 MHz but only under the Blender rendering benchmark, and not during heavy video game workloads. The GPU even accepted 3548 MHz through an imposing consumption of around 400 W.

Unfortunately under such a frequency, stability is a problem. In gaming, the maximum frequency reached was 2.990 GHz.

Testing was conducted with a Sapphire RX 7900 XTX NITRO+ graphics card equipped with three 8-pin PCIe power connectors and higher OC potential than a reference design.
