Intel Core i7 Mobile microprocessor family

i7-720QM and i7-820QM were the first two mobile microprocessors branded "Core i7 Mobile". The processors are based on 45nm Nehalem micro-architecture, and were launched 10 months after the first desktop Nehalem CPUs with Bloomfield core. Feature-wise these high-performance mobile microprocessors are similar to desktop CPUs with Lynnfield core - all of them have integrated dual-channel DDR3 memory controller, Direct Media Interface and PCI Express interface, rather than triple-channel memory controller and QPI interface on Bloomfield CPUs. While the clock frequency on i7-720QM and i7-820QM models is not as high as for desktop Core i7s, the mobile processors can operate at much higher frequencies when running single- and dual-threaded applications, owning to very powerful Turbo Boost feature. For example, for single-threaded tasks this feature can raise frequency of a single core up to 2.8 GHz for the i7-720QM, or 3.06 GHz for the i7-820QM.
