Iris Plus 640 vs Iris Plus 655 benchmarks

For gaming, the Iris Plus 640 graphics card is better than the Iris Plus 655 in our tests.

By comparing the spec sheets, both the Iris Plus 640 and the Iris Plus 655 have the same base clock speed. Despite this, the Iris Plus 640 has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, both the Iris Plus 640 and the Iris Plus 655 have an identical TDP. 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 Iris Plus 655.
