AMD Radeon RX 6600 vs AMD Radeon RX 7900 XTX

Radeon RX 6600 vs Radeon RX 7900 XTX specs and performance

In our benchmarks, the Radeon RX 7900 XTX beats the Radeon RX 6600 in gaming performance.

In our comparison, the Radeon RX 7900 XTX has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the Radeon RX 7900 XTX also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Next up, in terms of GPU memory, the Radeon RX 7900 XTX has significantly more memory with 24 GiB of memory compared to 8 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6600 has a significantly lower TDP at 132 W when compared to the Radeon RX 7900 XTX at 355 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 7900 XTX over the Radeon RX 6600.
