Radeon R9 390 vs GeForce GTX 980M comparison

In our benchmarks, the Radeon R9 390 beats the GeForce GTX 980M in gaming performance.

The GeForce GTX 980M has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the GeForce GTX 980M 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.

Next up, in terms of GPU memory, the Radeon R9 390 has significantly more memory with 8 GiB of memory compared to 4 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 980M has a significantly lower TDP at 100 W when compared to the Radeon R9 390 at 275 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 terms of raw gaming performance in our GPU benchmark, the Radeon R9 390 is better than the GeForce GTX 980M.
