GeForce GTX 950 vs Iris Xe comparison

For gaming, the GeForce GTX 950 graphics card is better than the Iris Xe in our tests.

The GeForce GTX 950 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 950 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the Iris Xe has a significantly lower TDP at 15 W when compared to the GeForce GTX 950 at 90 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 950 over the Iris Xe.
