Iris Plus 655 vs GeForce GTX 750 Ti specs and performance

For gaming, the GeForce GTX 750 Ti graphics card is better than the Iris Plus 655 in our tests.

The GeForce GTX 750 Ti has a significantly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the GeForce GTX 750 Ti also 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 655 has a significantly lower TDP at 15 W when compared to the GeForce GTX 750 Ti at 60 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 GTX 750 Ti over the Iris Plus 655.
