Radeon R9 280X vs Radeon RX 6950 XT specs and performance

For gaming, the Radeon RX 6950 XT graphics card is better than the Radeon R9 280X in our tests.

In our comparison, the Radeon RX 6950 XT has a significantly 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 6950 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 6950 XT has significantly more memory with 16 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 R9 280X has a slightly lower TDP at 250 W when compared to the Radeon RX 6950 XT at 335 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 6950 XT is faster than the Radeon R9 280X.
