Radeon RX 6800 XT vs Radeon RX 7900 XTX benchmarks

According to the hardwareDB Benchmark, the Radeon RX 7900 XTX GPU is faster than the Radeon RX 6800 XT in gaming.

The Radeon RX 6800 XT 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. Despite this, the Radeon RX 7900 XTX 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.

As stated by the manufacturer, 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 6800 XT has a slightly lower TDP at 300 W when compared to the Radeon RX 7900 XTX at 355 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 7900 XTX over the Radeon RX 6800 XT.
