GeForce GTX 1660 vs GeForce GTX 660 comparison

In our benchmarks, the GeForce GTX 1660 beats the GeForce GTX 660 in gaming performance.

The GeForce GTX 1660 has a significantly 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 1660 also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the GeForce GTX 1660 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 1660 has a slightly lower TDP at 120 W when compared to the GeForce GTX 660 at 140 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 1660 over the GeForce GTX 660.
