Radeon R9 280 vs Iris Xe benchmarks

In our benchmarks, the Radeon R9 280 beats the Iris Xe in gaming performance.

Our database shows that the Radeon R9 280 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. Despite this, the Iris Xe has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In addition, the Iris Xe has a significantly lower TDP at 15 W when compared to the Radeon R9 280 at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon R9 280 is faster than the Iris Xe.
