Iris Xe vs Radeon RX 7900 XTX comparison

In our benchmarks, the Radeon RX 7900 XTX beats the Iris Xe in gaming performance.

Our database shows that the Radeon RX 7900 XTX 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 7900 XTX 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.

In addition, the Iris Xe has a significantly lower TDP at 15 W when compared to the Radeon RX 7900 XTX at 355 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 7900 XTX over the Iris Xe.
