GeForce GTX 645 vs GeForce GTX 670 comparison

According to the hardwareDB Benchmark, the GeForce GTX 670 GPU is faster than the GeForce GTX 645 in gaming.

Furthermore, the spec sheet for both these GPUs show that the GeForce GTX 670 has significantly more memory with 4 GiB of memory compared to 1 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the GeForce GTX 645 has a significantly lower TDP at 64 W when compared to the GeForce GTX 670 at 170 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 670 is faster than the GeForce GTX 645.
