GeForce GTX 770 vs GeForce GTX 660 Ti specs and performance

According to the hardwareDB Benchmark, the GeForce GTX 770 GPU is faster than the GeForce GTX 660 Ti in gaming.

Our database shows that 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 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.

In addition, the GeForce GTX 660 Ti has a significantly lower TDP at 150 W when compared to the GeForce GTX 770 at 230 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 GeForce GTX 770 is faster than the GeForce GTX 660 Ti.
