GeForce RTX 3090 vs Radeon R9 390X comparison

For gaming, the GeForce RTX 3090 graphics card is better than the Radeon R9 390X in our tests.

The GeForce RTX 3090 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 RTX 3090 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.

As stated by the manufacturer, the GeForce RTX 3090 has significantly more memory with 24 GiB of memory compared to 8 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon R9 390X has a slightly lower TDP at 275 W when compared to the GeForce RTX 3090 at 350 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 GeForce RTX 3090 over the Radeon R9 390X.
