GeForce GTX 660M vs Radeon HD 8790M benchmarks

In our benchmarks, the GeForce GTX 660M beats the Radeon HD 8790M in gaming performance.

The GeForce GTX 660M has a slightly 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 GTX 660M also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Furthermore, the spec sheet for both these GPUs show that they both have the same amount of memory at 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In terms of raw gaming performance in our GPU benchmark, the GeForce GTX 660M is better than the Radeon HD 8790M.
