GeForce GTX 660M vs GeForce 830M comparison

For gaming, the GeForce GTX 660M graphics card is better than the GeForce 830M in our tests.

In our comparison, the GeForce 830M has a slightly 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 830M also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the GeForce 830M has a significantly lower TDP at 33 W when compared to the GeForce GTX 660M at 50 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce GTX 660M is better than the GeForce 830M.
