Radeon RX 7900 XTX vs Radeon RX 6850M XT comparison

In our benchmarks, the Radeon RX 7900 XTX beats the Radeon RX 6850M XT in gaming performance.

Our database shows that the Radeon RX 6850M 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. In addition, the Radeon RX 6850M XT 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.

As stated by the manufacturer, the Radeon RX 7900 XTX has significantly more memory with 24 GiB of memory compared to 12 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 6850M XT has a significantly lower TDP at 165 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.

According to the results of the hardwareDB benchmark utility, the Radeon RX 7900 XTX is faster than the Radeon RX 6850M XT.
