Intel Core i7 Mobile microprocessor family

First references to i7-640M model appeared in May 2010 in a leaked Intel roadmap. Preliminary price for the CPU was published at the end of June, and the first notebooks with the CPU were spotted in July. The CPU was released in September 2010 as part of a big launch of standard-, low- and ultra-low mobile Arrandale CPUs. Main differences of this microprocessor from the i7-620M model is 133 MHz higher core frequency, and higher Turbo Boost frequency.

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.

Core i7-740QM is the second model from the i7-7xx series of high-performance microprocessors. At this time, June 2010, the processor is not officially launched yet, although all major laptop manufacturers already announced laptops based on this CPU. One of the first spotted laptops with the i7-740QM was HP Envy 17, followed by Dell Studio 14 notebook. Other manufacturers, who prepared new laptop models with the CPU, are Toshiba X505-Q887, X505-Q888 and X505-Q890 notebooks, Hewlett Packard 8540p, 8540w and 8740w laptops, EUROCOM X8100 Leopard, Mouse Computer Company MB-G811B, Sony VAIO VPC-F127HG/BI, and Fujitsu Celsius H700 laptops.

i7-8xx line of mobile Core i7 microprocessors provides superior performance than i7-7xx series by enhancing a few processor features. The 820QM and upcoming 840QM processors run one step, or 133 MHz, faster than 7xx models released at the same time. Level 3 cache on 8xx line of processors is increased to 8 MB, and Turbo Boost frequency is usually by one or two steps higher than on the i7-7xx mobile CPUs. Better performance comes at premium price, though. While this CPU in some tasks can be faster than the i7-720QM by up to 15%, it currently (June 2010) has 50% higher price the 720QM.
