UHD 730 vs GeForce GTX 650 specs and performance
According to the hardwareDB Benchmark, the UHD 730 GPU is faster than the GeForce GTX 650 in gaming.
The GeForce GTX 650 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 UHD 730 has a significantly lower TDP at 15 W when compared to the GeForce GTX 650 at 64 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 UHD 730 over the GeForce GTX 650.
