GeForce GTX 770 vs Iris Xe specs and performance
For gaming, the GeForce GTX 770 graphics card is better than the Iris Xe in our tests.
Our database shows that the GeForce GTX 770 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. Despite this, the Iris Xe has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.
In addition, the Iris Xe has a significantly lower TDP at 15 W when compared to the GeForce GTX 770 at 230 W. Heat output doesn't match power consumption directly but, it's a good estimate.
In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 770 over the Iris Xe.
