Sandy Bridge Mobile is now available for the first time

Unlike desktop products, notebook processors are generally provided to OEM PC manufacturers for pre-installation, and are rarely seen in the retail market, and DIY upgrades are much more difficult than desktop computers. Three and a half years after the Sandy Bridge architecture was launched, we finally saw the retail version of the mobile model on the market for the first time.

The three retail-listed mobile versions of Sandy Bridge are the quad-core Core i7-2720QM and the dual-core Core i5-2540M, Core i5-2520M, both using the Socket G2 package interface (also known as PGA988B). The mobile chipset is not compatible with Socket G1 (also known as PGA988A) and 5 series chipsets used in the previous Arrandale Core ix series. The words "Requires Socket G1" on the side of the box should be ignored.

In addition to upgrading laptops, these mobile processors can also be used with motherboards that use 6 series mobile chipsets, such as iBASE's MI956 (QM67 chipset), Supermicro's Mini-ITX mini X9SCV-Q (QM67 chipset). )and many more. Unfortunately, this type of product is too small, and it is mostly oriented to professional fields. It is not easy to find in the retail market.

Core i7-2720QM is a quad-core eight-thread model with a frequency of 2.2GHz, an acceleration of up to 3.3GHz, a three-level cache of 6MB, an integrated graphics core HD Graphics 3000, a dynamic frequency of 650-1300MHz, and support for dual-channel DDR3-1600 memory. Capacity 16GB, a variety of processors, graphics technology readily available, thermal design power 45W.

The Core i5-2540M is a dual-core, four-threaded processor with a clock speed of 2.6GHz, an acceleration speed of up to 3.3GHz, a three-level cache of 3MB, a graphics core equivalent, and a memory drop of 8GB DDR3-1333, as much as the related technologies. The thermal design power consumption is 35W.

The Core i5-2520M is simple. The original frequency and acceleration frequency are reduced to 2.5GHz and 3.2GHz respectively. The others are the same as above.

The three S-Spec numbers are identified as SR014, SR048, and SR044, respectively.

Core i7-2720QM, Core i5-2540M/2520M official price is 378 US dollars, 266 US dollars, 225 US dollars, currently quoted in Japan's Akihabara market 34,480 yen, 24,980 yen, 20480-20980 yen, about Combined RMB 2760, 2000, and 1640-1680 yuan.
