Radeon R9 280 vs Radeon RX 7800 XT comparison

In our benchmarks, the Radeon RX 7800 XT beats the Radeon R9 280 in gaming performance.

Our database shows that the Radeon RX 7800 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 7800 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 7800 XT has significantly more memory with 16 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 R9 280 has a slightly lower TDP at 250 W when compared to the Radeon RX 7800 XT at 263 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 7800 XT is better than the Radeon R9 280.
