GeForce GTX 660 vs GeForce RTX 4090 benchmarks

According to the hardwareDB Benchmark, the GeForce RTX 4090 GPU is faster than the GeForce GTX 660 in gaming.

Our database shows that the GeForce RTX 4090 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 4090 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 4090 has significantly more memory with 24 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 significantly lower TDP at 140 W when compared to the GeForce RTX 4090 at 450 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 4090 over the GeForce GTX 660.
