Surprisingly or not, the GM107 has landed in mobile segment. The newest GeForce 800M series will kick off with Maxwell GPUs very soon.
NVIDIA GeForce GTX 860M specifications
GeForce GTX 860M will use the same GPU variant as desktop GTX 750 Ti. It packs 640 CUDA cores, 40 TMUs and 16 ROPs. The GPU-Z didn’t read core clocks correctly, so all we have is memory clock of 1253 MHz (5 GHz effective).
The score of 5339 points in 3DMark 11 suggest we are looking at performance level above GTX 770M. This is somewhere in-between desktop GTX 650 TI Boost and R7 260X. Simply put, it’s a great performance. However, in Extreme profile we have slightly lower score than GTX 770M, but I think it’s safe to say that these cards are comparable, and let’s not forget, Maxwell has a great overclocking potential.
The benefit of GTX 770M over GTX 860M is wider interface (192b vs 128b), but it also consumes more power (75W vs ~45W). The GTX 860M offers less memory (2GB vs 3GB), but as long as we are looking at 1080p notebooks, it shouldn’t really matter.
