Radeon RX 6800 vs Radeon RX 7900 XTX comparison

For gaming, the Radeon RX 7900 XTX graphics card is better than the Radeon RX 6800 in our tests.

Our database shows that the Radeon RX 7900 XTX has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. 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 16 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6800 has a slightly lower TDP at 250 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 conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 7900 XTX over the Radeon RX 6800.
