GeForce GTX 1660 SUPER vs GeForce RTX 3080 comparison
According to the hardwareDB Benchmark, the GeForce RTX 3080 GPU is faster than the GeForce GTX 1660 SUPER in gaming.
The GeForce GTX 1660 SUPER 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 1660 SUPER 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 RTX 3080 has significantly more memory with 10 GiB of memory compared to 6 GiB. Lots of memory is good when playing at high resolutions or with many monitors.
In addition, the GeForce GTX 1660 SUPER has a significantly lower TDP at 125 W when compared to the GeForce RTX 3080 at 320 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.
In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 3080 over the GeForce GTX 1660 SUPER.
