GeForce GTX 660 vs GeForce RTX 4070 specs and performance

According to the hardwareDB Benchmark, the GeForce RTX 4070 GPU is faster than the GeForce GTX 660 in gaming.

In our comparison, the GeForce RTX 4070 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 4070 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.

Furthermore, the spec sheet for both these GPUs show that the GeForce RTX 4070 has significantly more memory with 12 GiB of memory compared to 3 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 660 has a significantly lower TDP at 140 W when compared to the GeForce RTX 4070 at 300 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 4070 over the GeForce GTX 660.
