GeForce GTX 980 Ti vs GeForce GTX 660 comparison

According to the hardwareDB Benchmark, the GeForce GTX 980 Ti GPU is faster than the GeForce GTX 660 in gaming.

In our comparison, the GeForce GTX 980 Ti 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 980 Ti also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Next up, in terms of GPU memory, the GeForce GTX 980 Ti has significantly more memory with 6 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 660 has a significantly lower TDP at 140 W when compared to the GeForce GTX 980 Ti at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 980 Ti over the GeForce GTX 660.
