Radeon R9 280X vs Radeon RX 6600 XT specs and performance

In our benchmarks, the Radeon RX 6600 XT beats the Radeon R9 280X in gaming performance.

In our comparison, the Radeon RX 6600 XT has a significantly 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 6600 XT also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the Radeon RX 6600 XT has significantly more memory with 8 GiB of memory compared to 3 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6600 XT has a significantly lower TDP at 160 W when compared to the Radeon R9 280X at 250 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 6600 XT over the Radeon R9 280X.
