GeForce GTX 950 vs Iris Plus 655 benchmarks

In our benchmarks, the GeForce GTX 950 beats the Iris Plus 655 in gaming performance.

In our comparison, the GeForce GTX 950 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 GTX 950 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 950 at 90 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 950 over the Iris Plus 655.
