Iris Plus 640 vs UHD 605 specs and performance

In our benchmarks, the Iris Plus 640 beats the UHD 605 in gaming performance.

Our database shows that the Iris Plus 640 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 Iris Plus 640 also has a significantly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

In addition, the UHD 605 has a significantly lower TDP at 5 W when compared to the Iris Plus 640 at 15 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Iris Plus 640 over the UHD 605.
