AMD announces Radeon HD 7000M series with Enduro graphics-switching technology

AMD kicked off 2012 by refreshing its desktop graphics, and now it's back, giving its mobile GPUs the same treatment. The company just announced its third generation of DirectX 11 mobile chips, the Radeon HD 7000 family. All told, the collection includes three 28nm GPUs: the high-end 7900M, the mainstream 7800M and, last but not least, the 7700M, a darling little chip intended for AMD's thin and light Ultrabook competitors. Across the board, the series ushers in a new feature AMD is calling Enduro, a graphics-switching technology that takes direct aim at NVIDIA Optimus. Building on older AMD technologies like PowerXpress, it doesn't require you to close apps, reboot your system or manually specify which apps will trigger the GPU.
Additionally, it's designed to work with both Intel CPUs and AMD's own application processing units, so presumably you'll find this inside some Ivy Bridge machines too. With this generation, too, the two higher-end chips support the PCI Express 3.0 interface, and all three make use of AMD's existing ZeroCore Power and Power Gating battery-saving features. That's the abridged version, but we also have a full breakdown of the specs awaiting you past the break.

NVIDIA: there's nothing 'Ultra' about Ivy Bridge Ultrabooks unless you add Kepler

This is a vaguely awkward message for NVIDIA to be putting out. On one hand, the company is best buddies with Intel and is hoping to see its next-gen GPUs bundled with a large portion of the Ivy Bridge notebooks that will ship this year. But to reach that target, it must risk irking Chipzilla by emphasizing the limitations of Ivy Bridge's integrated graphics. That's exactly what happened at a recent presentation, when NVIDIA told us there'll be "nothing Ultra" about the performance of a regular Ivy Bridge Ultrabook because the integrated HD 4000 graphics will only handle around 43 percent of current games.
By contrast, if you add in a GeForce GT 640M you'll find that 100 percent of current games are playable with frame rates over 30fps and high detail settings, including Battlefield 3, Batman: Arkham City, Crysis 2 and many others. If you leave the lightweight Ultrabook spec behind and combine Ivy Bridge with a GT 670M GPU then you can go even higher -- as we just discovered in our review of the MSI's GT70 gaming laptop. Fortunately, Intel was pretty magnanimous about HD 4000 when it briefed us, and readily accepted that enthusiasts will still want discrete graphics, so we don't imagine the slide above will cause too many hurt feelings.
