GeForce GTX 1060 vs GeForce GT 1030 benchmarks
According to the hardwareDB Benchmark, the GeForce GTX 1060 GPU is faster than the GeForce GT 1030 in gaming.
The GeForce GTX 1060 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 GT 1030 has a significantly lower TDP at 30 W when compared to the GeForce GTX 1060 at 120 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 GTX 1060 over the GeForce GT 1030.
