UHD 770 vs GeForce GTX 660 specs and performance

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

The GeForce GTX 660 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. Despite this, the UHD 770 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.

In addition, the UHD 770 has a significantly lower TDP at 15 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 660 over the UHD 770.
