Main Description

• The first generation of mobile CPU production consists of the i5-500 series for the Intel Core i5; and i7-600, i7-700 and i7-800 series for the Intel Core i7. The second production cycle comprises the i5- and i7-2000 series. All processors except for the i7-700 and i7-800 series use the 32-nanometer manufacturing process; the aforementioned series use the 45-nm method instead, which makes them larger chips.
  
  

Cores and Speeds

• The four entries of the i7-700 and i7-800 series join four others of the mobile Intel Core i7's second generation as quad-core chips, thus using the "QM" suffix. The other i5 and i7 laptop processors are dual-core CPUs, thus making them half as powerful. The i5 and i7 Mobile have base processor speed ranges of 1.06 GHz to 2.66 GHz and 1.06 GHz to 2.8 GHz, respectively. The first-generational chips have a data transfer speed of 2.5 billion transfers per second and the second-generational chips double that number.
  
  

Smart Cache and Power Consumption

• Each Intel Core i5 and i7 laptop processor has a Smart Cache, a small storage unit that the processor uses for faster access to the laptop's most frequently used data than the system memory. Each i5 mobile CPU has a 3MB Smart Cache. The memory bank capability of the i7 varies, with choices of 4MB, 6MB and 8MB. In terms of power consumption, the i5 has a peak thermal design point range of 17 to 35 watts. The i7 has entries that match the most energy efficient i5 chips with a 17W rating, but its least efficient ones peak at 45W.
  
  

Main Technologies

• Each Intel Core i5 and i7 laptop processor has Intel Turbo Boost, a technology that increases the processing speed when the operating system demands optimal performance -- as high as 3.33 GHz and 3.46 GHz for the i5 and i7, respectively. Apart from the i5-2467M and the i7-700 and i7-800 series, all i5 and i7 mobile CPU has a built-in chipset called "Intel HD Graphics," which enables graphics processing from the computer chip.
