GeForce GTX 660 vs GeForce RTX 5070 specs and performance

According to the hardwareDB Benchmark, the GeForce RTX 5070 GPU is faster than the GeForce GTX 660 in gaming.

In our comparison, the GeForce RTX 5070 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 5070 also has a significantly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

In addition, the GeForce GTX 660 has a significantly lower TDP at 140 W when compared to the GeForce RTX 5070 at 250 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 GeForce RTX 5070 over the GeForce GTX 660.
