Radeon RX 7900 XTX vs Radeon RX 7800 XT benchmarks

According to the hardwareDB Benchmark, the Radeon RX 7900 XTX GPU is faster than the Radeon RX 7800 XT in gaming.

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. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Next up, in terms of GPU memory, the Radeon RX 7900 XTX has significantly more memory with 24 GiB of memory compared to 16 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon RX 7800 XT has a slightly lower TDP at 263 W when compared to the Radeon RX 7900 XTX at 355 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 7900 XTX is better than the Radeon RX 7800 XT.
