A Reddit forum user overclocked the graphics processor of the graphics card Radeon RX 7900. The 7900 XTX TUF Gaming model was used, the standard cooling system of which was replaced by the EK Quantum Vector water block. The latter was connected to a radiator with coolant, the temperature of which was lowered to 10 °C.

Modifying the graphics card allowed it to match the performance of the GeForce RTX 4090 in the synthetic test of the 3DMark package, where it could stably work at a more modest frequency of 3.33 GHz. True, the minus here is the power consumption of the accelerator, which was just under 700 watts. That’s more than double the standard 335W for the RX 7900 XTX. For comparison: The power consumption of the GeForce RTX 4090 specified by the manufacturer is 400-500 watts in the same tests.
In the 3DMark Time Spy Extreme test, the overclocked Radeon RX 7900 scored just 16,654 in the same test, which is 10% lower than the result of a Radeon graphics card overclocked by a Reddit user.
The experiment shows that the Radeon RX 7900 And, of course, the same 3DMark test does not reflect the full picture of the accelerator’s gaming performance, and the Reddit user did not run gaming tests of the overclocked Radeon graphics card.
In March, AMD announced that it could release a direct competitor to the GeForce RTX 4090. However, this has not been done due to the potentially high power consumption of such a solution and the cost. The experiment confirms AMD’s words.
“Technically, within the framework of the RDNA 3 architecture, it is possible to develop GPUs with characteristics that could compete with them (with NVIDIA and its GeForce RTX 4090 – editor’s note). The PC gamer community eventually accepted a graphics card with a TDP of $1,600. But after some deliberation, we decided not to follow this strategy. The Radeon RX 7900 we released We also released the Radeon RX 7900 XT for $899.Rick Bergman, vice president of computer and graphics products at AMD, commented at the time.
