GeForce GTX 970 vs GeForce GTX 660 Ti benchmarks

For gaming, the GeForce GTX 970 graphics card is better than the GeForce GTX 660 Ti in our tests.

The GeForce GTX 970 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 970 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.

Furthermore, the spec sheet for both these GPUs show that the GeForce GTX 970 has slightly more memory with 4 GiB of memory compared to 3 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 970 has a slightly lower TDP at 145 W when compared to the GeForce GTX 660 Ti at 150 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 970 is faster than the GeForce GTX 660 Ti.
