Radeon R9 390 vs GeForce GTX 770 comparison

In our benchmarks, the Radeon R9 390 beats the GeForce GTX 770 in gaming performance.

The GeForce GTX 770 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 GTX 770 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the GeForce GTX 770 has a slightly lower TDP at 230 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 GeForce GTX 770.
