Intel Sandy Bridge core

Sandy Bridge core was introduced on January 9, 2011, when Intel launched first desktop and mobile Core i5 and core i7 CPUs, based on Sandy Bridge microarchitecture. All processors with this core are manufactured on 32nm technology, and incorporate 2 or 4 cores, with 64KB L1 and 256 KB L2 cache per each core, and with up to 8 MB shared L3 cache. Many Sandy Bridge models support Advanced Vector Extensions instructions, as well as all features, available in previous generations of Nehalem/Westmere microprocessors. Desktop Sandy Bridge parts are produced in LGA1155 package, compatible with socket 1155, and mobile processors are packaged in PGA988 micro-PGA (socket G2), or BGA1023 and BGA1224 packages.

New core features:

  • CPU cores, graphics and memory controllers are on a single die.
  • New Advanced Vector Extensions (AVX) 256-bit SIMD instructions.
  • Direct Media Interface 2.0 with twice higher 5 GT/s data rate.
  • Support for Active Management Technology 7.0.
  • Turbo Boost 2.0.
  • Improved HD 3000 or HD 2000 graphics controller with enhanced performance and new features.

Intel processors with Sandy Bridge core can be identified by:

  • OEM part number: part numbers of desktop dual-cores start from "CM80623", and mobile CPUs start from "AV80627" or "FF80627".
    An example: AV8062700834912, CM8062301002115.
  • Box part number: part numbers of desktop models start from "BX80623" or "BXC80623", and mobile CPUs start from "BX80627".
    An example: BXC80623I32100T, BX80627I52520M.

Below is a list of all Sandy Bridge microprocessor families.
