GeForce RTX 3080 vs Radeon R9 390 specs and performance

For gaming, the GeForce RTX 3080 graphics card is better than the Radeon R9 390 in our tests.

The GeForce RTX 3080 has a significantly 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 RTX 3080 also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the GeForce RTX 3080 has slightly more memory with 10 GiB of memory compared to 8 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon R9 390 has a slightly lower TDP at 275 W when compared to the GeForce RTX 3080 at 320 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 3080 is better than the Radeon R9 390.
