Radeon HD 8790M vs GeForce GTX 880M comparison

For gaming, the GeForce GTX 880M graphics card is better than the Radeon HD 8790M in our tests.

The GeForce GTX 880M has a slightly 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 880M also 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 conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 880M over the Radeon HD 8790M.
