GeForce RTX 3070 vs GeForce GTX 660 specs and performance

According to the hardwareDB Benchmark, the GeForce RTX 3070 GPU is faster than the GeForce GTX 660 in gaming.

In our comparison, the GeForce RTX 3070 has a significantly 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. In addition, the GeForce RTX 3070 also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the GeForce RTX 3070 has significantly more memory with 8 GiB of memory compared to 3 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the GeForce GTX 660 has a significantly lower TDP at 140 W when compared to the GeForce RTX 3070 at 220 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 3070 is better than the GeForce GTX 660.
