CHIP DESIGNER Nvidia has released its Geforce GTX 680M for gaming laptops.
Nvidia has showcased its vaunted Kepler architecture in a number of cards, most notably the Geforce GTX 690, however the firm knows that the enthusiast mobile gaming market is growing. To cater to it, Nvidia launched the Geforce GTX 680M, a slightly cut down version of the GPU that powers the Geforce GTX 680 desktop card.
Nvidia's reference Geforce GTX 680M specification suggests the firm hasn't cut all that much from the desktop GPU, with 1344 cores clocked at up to 720MHz. The firm has specified 4GB of 256bit GDDR5 memory, which is actually double what many desktop Geforce GTX 680 boards have, and has clocked the memory up to 1,800MHz.
Unlike some of Nvidia's 600 series mobile chips, the Geforce GTX 680M is a GPU based on the Kepler architecture and carries some of its desktop features. The firm has brought over its adaptive Vsync technology to reduce screen tearing, along with FXAA and TXAA anti-aliasing.
For those wanting to carry a briefcase of a laptop, Nvidia's Geforce GTX 680M supports SLI, with Alienware's M18x being the first laptop at launch to have two Geforce GTX 680M chips driving its 18.4in screen. MSI and Clevo also have models that feature the Geforce GTX 680M.
Nvidia's Kepler architecture has helped the firm come back with a vengeance, and while the Geforce GTX 680M is very much a niche product, it should help Nvidia compete closely with AMD's Radeon HD 7970M. µ
