Average Performance And Efficiency
The GK106-equipped GeForce GTX 770M appears out of place compared to GK104-based 880M, 780M, and 860M models. That's one reason we need to stay cautious about references to the GeForce GTX 860M, which is available as two different GPUs. Even though Nvidia appears to be running its efficient GM107 processor at close-to-desktop frequencies, there's just no way to know where it falls in the following chart until benchmark data is available.
Anyone who spends a lot of time gaming should be happy to know that performance increases proportionally with power. All three of Nvidia's new modules improve frame rates enough to bolster efficiency compared to the modules they replace, and that's what we want to see.
