Radeon HD 8790M vs GeForce 940MX specs and performance

For gaming, the Radeon HD 8790M graphics card is better than the GeForce 940MX in our tests.

In our comparison, the GeForce 940MX 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 940MX also has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon HD 8790M over the GeForce 940MX.
