INTEL® MICROARCHITECTURE CODENAME SANDY BRIDGE

The next-generation Intel® microarchitecture codename Sandy Bridge is an incredible leap in processor integration and manufacturing. Introduced in the 2nd generation Intel® Core™ processor family, some of the highlights of this new microarchitecture include:

  • Manufactured entirely on Intel® 32nm process technology, delivering yet another leap in performance and energy efficiency beyond previous generation process technologies.
  • All cores plus graphics are integrated on a single chip, enabling new levels of visual experiences on a PC.
  • Even more performance boost when you need it with Intel® Turbo Boost 2.0.
  • Yet another step in increased efficiency by intelligently matching performance to workloads, while optimizing power efficiency across cores and graphics engine.

Fully integrated microarchitecture

Sandy Bridge Model

Sandy Bridge unifies processor cores, memory controller, last-level cache (LLC), and graphics and media processing. Such tight integration enables a host of performance and efficiency improvements, such as:

  • Fast access by cores and graphics to shared data in the last-level cache accelerates graphics processing.
  • Fewer buses over which data and signaling must travel mean faster processing.
  • More memory bandwidth for the cores boosts system performance.

Smart performance boosts for graphics and media processing

Sandy Bridge with built-in visuals◊ is optimized for next-generation media workloads. New technologies include:

  • A much more powerful graphics engine than previous Intel microarchitectures speeds 3D and video processing.
  • New hardware-based media accelerators and graphics execution units deliver superior performance for gaming, HD video content, and 3D graphics.
  • New technologies that allow you to truly enjoy all your HD content and web experiences.

Dynamic performance for both processor and graphics

Intelligent power management with Intel® Turbo Boost 2.0◊ dynamically controls performance and power—for both cores and graphics—boosting performance exactly where and when it is needed, and saving energy when it counts.

Design scalability for a wide range of markets

Sandy Bridge addresses servers, workstations, notebooks, and desktop segments with support for two to eight or more cores and up to sixteen or more threads withIntel® Hyper-Threading Technology (Intel® HT Technology)◊. This new microarchitecture also enables thinner form factors, improved battery life, and active energy efficiency for mobile computing applications.

Double the FLOPS, and more

Compute intensive applications get a boost with Intel® Advanced Vector Extensions (Intel® AVX), a new, 256 bit instruction set extension to Intel® SSE. Intel AVX along with new Advanced Encryption Standard (AES), operating system, and virtual machine manager (VMM) enhancements extend the architecture for important new applications.
