GeForce GTX 780 vs Iris Xe specs and performance

According to the hardwareDB Benchmark, the GeForce GTX 780 GPU is faster than the Iris Xe in gaming.

The GeForce GTX 780 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. Despite this, the Iris Xe 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 Xe has a significantly lower TDP at 15 W when compared to the GeForce GTX 780 at 250 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 780 over the Iris Xe.
