Virtually all the essential details for Intel's first mobile chips based on the Nehalem architecture have escaped today courtesy of a roadmap. It now says the quad-core Clarksfield processors at 1.6GHz, 1.73GHz and 2GHz will be named the i7-720QM, i7-820QM and i7-920XM respectively with 8MB of cache on all but the slowest model. In a surprise, however, all three will also have dramatic headroom for increased clock speeds and should scale up to 2.8GHz, 3.06GHz and 3.2GHz. It's implied in the Impress leak that these speeds will come through Turbo Boost, a feature that shuts down one or more of the cores in return for higher clock speeds for tasks that don't need every core.
Intel at the International Solid-State Circuits Conference today provided some of the first concrete details of Westmere, the codename for its 32 nanometer processor family. The design is primarily a smaller, more efficient adaptation of the Nehalem architecture in the Core i7 but, in the dual-core desktop (Clarkdale) and notebook (Arrandale) offerings, will include both a two-channel DDR3 memory interface and an integrated but switchable graphics core. Like NVIDIA's Hybrid SLI mode or AMD's Hybrid CrossFire, the technology will let systems with dedicated graphics chipsets revert to Intel's own core in low-demand situations or when on battery.
