HD 4000 vs Iris Plus 640 specs and performance

In our benchmarks, the Iris Plus 640 beats the HD 4000 in gaming performance.

The HD 4000 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 Plus 640 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 Plus 640 has a significantly lower TDP at 15 W when compared to the HD 4000 at 45 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the Iris Plus 640 over the HD 4000.
