Iris Plus 640 vs UHD 770 benchmarks

According to the hardwareDB Benchmark, the UHD 770 GPU is faster than the Iris Plus 640 in gaming.

By comparing the spec sheets, both the Iris Plus 640 and the UHD 770 have the same base clock speed. Despite this, the UHD 770 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, both the Iris Plus 640 and the UHD 770 have an identical TDP. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the UHD 770 is better than the Iris Plus 640.
