GeForce GTX 970 vs GeForce 920MX comparison

For gaming, the GeForce GTX 970 graphics card is better than the GeForce 920MX in our tests.

Our database shows that the GeForce GTX 970 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 970 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the GeForce 920MX has a significantly lower TDP at 16 W when compared to the GeForce GTX 970 at 145 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 970 over the GeForce 920MX.
