Radeon R9 280 vs Radeon RX 6600 XT comparison

For gaming, the Radeon RX 6600 XT graphics card is better than the Radeon R9 280 in our tests.

Our database shows that the Radeon RX 6600 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 6600 XT also has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

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. 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 6600 XT has a significantly lower TDP at 160 W when compared to the Radeon R9 280 at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 6600 XT is better than the Radeon R9 280.
