GeForce GTX 660 Ti vs GeForce GTX 780 benchmarks

According to the hardwareDB Benchmark, the GeForce GTX 780 GPU is faster than the GeForce GTX 660 Ti in gaming.

In our comparison, the GeForce GTX 660 Ti has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the GeForce GTX 660 Ti 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.

Next up, in terms of GPU memory, the GeForce GTX 780 has significantly more memory with 6 GiB of memory compared to 3 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the GeForce GTX 660 Ti has a significantly lower TDP at 150 W when compared to the GeForce GTX 780 at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce GTX 780 is better than the GeForce GTX 660 Ti.
