Iris Plus 655 vs UHD 770 specs and performance

According to the hardwareDB Benchmark, the UHD 770 GPU is faster than the Iris Plus 655 in gaming.

By comparing the spec sheets, both the Iris Plus 655 and the UHD 770 have the same base clock speed. Despite this, the UHD 770 has a slightly 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, both the Iris Plus 655 and the UHD 770 have an identical TDP. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the UHD 770 is faster than the Iris Plus 655.
