GeForce GTX 770M vs Radeon 660M benchmarks

For gaming, the GeForce GTX 770M graphics card is better than the Radeon 660M in our tests.

Our database shows that the Radeon 660M has a significantly 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 660M also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the Radeon 660M has a significantly lower TDP at 15 W when compared to the GeForce GTX 770M at 75 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 770M is faster than the Radeon 660M.
