GeForce RTX 2080 Ti vs Radeon R9 390 specs and performance

In our benchmarks, the GeForce RTX 2080 Ti beats the Radeon R9 390 in gaming performance.

Our database shows that the GeForce RTX 2080 Ti 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 RTX 2080 Ti also has a significantly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Furthermore, the spec sheet for both these GPUs show that the GeForce RTX 2080 Ti has slightly more memory with 11 GiB of memory compared to 8 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce RTX 2080 Ti has a slightly lower TDP at 250 W when compared to the Radeon R9 390 at 275 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 2080 Ti is better than the Radeon R9 390.
