Radeon R9 390 vs GeForce RTX 4090 comparison

In our benchmarks, the GeForce RTX 4090 beats the Radeon R9 390 in gaming performance.

The GeForce RTX 4090 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 4090 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.

Next up, in terms of GPU memory, the GeForce RTX 4090 has significantly more memory with 24 GiB of memory compared to 8 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon R9 390 has a significantly lower TDP at 275 W when compared to the GeForce RTX 4090 at 450 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce RTX 4090 is faster than the Radeon R9 390.
