Radeon R9 380 vs GeForce 920MX comparison

For gaming, the Radeon R9 380 graphics card is better than the GeForce 920MX in our tests.

In our comparison, the Radeon R9 380 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. Despite this, the GeForce 920MX 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 GeForce 920MX has a significantly lower TDP at 16 W when compared to the Radeon R9 380 at 190 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon R9 380 over the GeForce 920MX.
