Iris Plus 655 vs GeForce RTX 3090 Ti benchmarks

For gaming, the GeForce RTX 3090 Ti graphics card is better than the Iris Plus 655 in our tests.

The GeForce RTX 3090 Ti 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. In addition, the GeForce RTX 3090 Ti also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the Iris Plus 655 has a significantly lower TDP at 15 W when compared to the GeForce RTX 3090 Ti at 450 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 GeForce RTX 3090 Ti over the Iris Plus 655.
