GeForce GT 730 vs GeForce GTX 660 comparison
According to the hardwareDB Benchmark, the GeForce GTX 660 GPU is faster than the GeForce GT 730 in gaming.
The GeForce GTX 660 has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. Despite this, the GeForce GT 730 has a slightly 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 660 has significantly more memory with 3 GiB of memory compared to 2 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 GT 730 has a significantly lower TDP at 49 W when compared to the GeForce GTX 660 at 140 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 terms of raw gaming performance in our GPU benchmark, the GeForce GTX 660 is better than the GeForce GT 730.
