GeForce RTX 2070 vs GeForce GTX 660 benchmarks

For gaming, the GeForce RTX 2070 graphics card is better than the GeForce GTX 660 in our tests.

In our comparison, the GeForce RTX 2070 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 GeForce RTX 2070 also has a significantly 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 RTX 2070 has significantly more memory with 8 GiB of memory compared to 3 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 GTX 660 has a slightly lower TDP at 140 W when compared to the GeForce RTX 2070 at 175 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the GeForce RTX 2070 is faster than the GeForce GTX 660.
