NVIDIA GeForce Go 7950 GTX Preview

Introduction and Specifications

The enthusiast gaming notebook has become an extremely viable and desirable alternative to today's desktop systems, which in-part explains why the mobile segment is one of the fastest growing in the PC industry. The latest crop of high performance notebooks are an engineering marvel of sorts, as they come dangerously close to providing the same levels of performance without the excessive bulk and heat associated with a full desktop system. Over the course of the last year in particular, we have witnessed the notebook gain further ground on desktops with the arrival of new processors and NVIDIA's SLI multi-GPU configurations on the notebook platform. As such, we now have the ability to run extremely potent CPUs, multiple flagship GPUs, and other enthusiast-class hardware without the need for a 700W power supply or some obnoxiously loud cooling solution.

Today, NVIDIA takes the notebook platform yet another step closer to enthusiast desktop performance with the launch of the new GeForce Go 7950 GTX. As the company's new flagship mobile GPU, this graphics chipset offers unprecedented performance for the notebooks without sacrificing the features and functionality a notebook demands. Going through the specifications, it is hard to not be impressed by NVIDIA's latest mobile creation.
