GeForce GTX 660M vs Radeon HD 7670M specs and performance

In our benchmarks, the GeForce GTX 660M beats the Radeon HD 7670M in gaming performance.

The GeForce GTX 660M 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.

As stated by the manufacturer, the GeForce GTX 660M has significantly more memory with 2 GiB of memory compared to 1 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 Radeon HD 7670M has a significantly lower TDP at 20 W when compared to the GeForce GTX 660M at 50 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 GTX 660M over the Radeon HD 7670M.
