Nvidia’s GeForce GTX 480M may hold the mobile performance crown, but GF100 is certainly not the most practical solution when it comes to power and heat. Today we see how its newer, smaller sibling stands up to the same tasks, aided by SLI support.
Power and heat have long been the biggest obstacles to achieving smoking-fast performance on a portable device, as the larger enclosures needed to support high-performance hardware often leaves them less than mobile. It’s no small wonder that we had big concerns when Nvidia re-purposed its power-hungry GF100 GPU as a notebook component.
The fastest “portable” GPU ever produced, the GeForce GTX 480M was already beaten by a CrossFire'd pair of Mobility Radeon HD 5870 modules when it was launched. Most extra-large notebooks couldn’t support an SLI'd pair of GeForce GTX 480M modules, and the one notebook that does support these still has some power problems in such a demanding configuration. Price was another barrier for many customers, since big pieces of silicon cost big money.
A bit of additional refinement on its desktop 400-series allowed Nvidia to re-evaluate its portfolio in an effort to find a new, more energy-efficient Radeon HD 5870-killer.
That new product, the GeForce GTX 460M, should fit into the majority of chassis that formerly hosted such big-ticket parts as its competitor’s flagship, as well as its previous mobile performance star, the GTX 285M, in dual-GPU configurations.
Before we go into the new GPU’s specifics, let’s take a quick look at the system we received to host Nvidia’s latest SLI-capable modules.

While the desktop-based CPU in AVADirect’s X7200 build left us with a few questions about which of our previously-tested notebooks might make this a fair comparison, its $3142 price will at least allow a performance-per-dollar analysis.
