NVIDIA GeForce GTX 770M and 780M

Around the same time the 8970M from AMD was announced, NVidia touted their latest 7xxM (for notebooks) as well. The new generation shows promise - largely thanks to higher clock speeds, but for now, we are focusing on the two top players: the GTX 770M and the GTX 780M.

NVidia continues its implementation of Opimus in many notebooks (Asus being one of the few to not incorporate it), allowing for greater battery optimization, as the notebook hands off graphical applications to Intel's integrated graphics chip when the dedicated graphics card is not in use. Most enthusiasts, gamers, and/or professionals that need the horsepower the NVidia card provides are more likely to adjust their power settings for "Performance", so that they need not worry about this on-the-fly graphics switching. Nevertheless, anyone on the go will benefit from the feature, so long as their demands are not requiring the dedicated card for non-stop use.

The reported claims in the performance gap when compared to the previous generation of GTX GeForce cards are as follows: GTX 760M is 30% faster than GTX 660M, GTX 770M is 55% faster than 670M and the GTX 780M is 31% faster than the GTX 680M. Of course, these proposed differences in performance are theoretical claims, which – as most know – seldom equate to real world tests. But the benchmarks give an idea of what we can expect from NVidia's latest and greatest, and do they ever deliver!
