Radeon R9 390 vs Radeon RX 580 2048SP benchmarks

In our benchmarks, the Radeon R9 390 beats the Radeon RX 580 2048SP in gaming performance.

In our comparison, the Radeon RX 580 2048SP 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 Radeon RX 580 2048SP also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the Radeon RX 580 2048SP has a significantly lower TDP at 150 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.

According to the results of the hardwareDB benchmark utility, the Radeon R9 390 is faster than the Radeon RX 580 2048SP.
