Radeon R9 280X vs Radeon RX 6500M benchmarks

For gaming, the Radeon R9 280X graphics card is better than the Radeon RX 6500M in our tests.

Our database shows that the Radeon RX 6500M 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 6500M also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the Radeon RX 6500M has slightly more memory with 4 GiB of memory compared to 3 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6500M has a significantly lower TDP at 50 W when compared to the Radeon R9 280X at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon R9 280X over the Radeon RX 6500M.
