Radeon R9 M375X vs Radeon HD 8790M specs and performance

For gaming, the Radeon HD 8790M graphics card is better than the Radeon R9 M375X in our tests.

Our database shows that the Radeon R9 M375X 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 Radeon R9 M375X also 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.

As stated by the manufacturer, the Radeon R9 M375X has significantly more memory with 4 GiB of memory compared to 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In terms of raw gaming performance in our GPU benchmark, the Radeon HD 8790M is better than the Radeon R9 M375X.
