Because the company was able to cram high-performance, desktop-class GPUs into notebooks, NVIDIA is claiming true 4K and 120Hz gaming is now possible for the very first time on a notebook PC platform. Exactly how NVIDIA achieved this seemingly bold defiance of the laws of physics, essentially fitting desktop graphics engines into the thermal and power envelope of notebook platforms is where the rubber meets the road. We'll dive into the architecture in more detail later, but essentially through careful binning of chips, voltage tweaks, and some board-level power optimizations on the MXM mobile GPU modules, NVIDIA was able to employ essentially the same silicon hardware in their notebook variants of the Geforce GTX 1080, 1070 and 1060.That's selling the semiconductor process side of things a bit short, however. We'd be remiss if we didn't underscore the fact that the migration down from a 28nm (nanometer) process on the previous generation Maxwell mobile GeForce family, to a 16nm FinFET process in Pascal has delivered a "quantum leap," as NVIDIA likes to call it, in power efficiency and performance-per-watt. Ais defined as a discontinuous change in state of an electron from one energy level to another. And that indeed would be fitting for what NVIDIA has achieved.
