Sandy Bridge is thecodename for Intel's32 nmmicroarchitecture used in the second generation of theIntel Core processors (Core i7,i5,i3). The Sandy Bridge microarchitecture is the successor toNehalem andWestmere microarchitecture. Intel demonstrated an A1stepping Sandy Bridge processor in 2009 duringIntel Developer Forum (IDF), and released first products based on the architecture in January 2011 under theCore brand.[2][3]
Sandy Bridge is manufactured in the32 nm process and has a soldered contact with the die and IHS (Integrated Heat Spreader), while Intel's subsequent generationIvy Bridge uses a22 nmdie shrink and a TIM (Thermal Interface Material) between the die and the IHS.
Upgraded features fromNehalem include:

All Sandy Bridge processors with one, two, or four cores report the same CPUID model 0206A7h[17] and are closely related. The stepping number cannot be seen from the CPUID but only from the PCI configuration space. The laterSandy Bridge-E processors with up to eight cores and no graphics are using CPUIDs0206D6h and0206D7h.[18] Ivy Bridge CPUs all have CPUID 0306A9h to date, and are built in four different configurations differing in the number of cores, L3 cache and GPU execution units:
| Die codename | CPUID | Stepping | Cores | GPU EUs | L3 cache | Socket(s) |

Suffixes to denote:
On 31 January 2011, Intel issued a recall on all 67-series motherboards due to a flaw in theCougar Point Chipset.[36] A hardware problem exists, in which the chipset'sSATA II ports may fail over time, causing failure of connection to SATA devices, though data is not at risk.[37] Intel claims that this problem will affect only 5% of users over 3 years; however, heavier I/O workloads can exacerbate the problem. This hardware bug cannot be fixed by BIOS update.
Intel stopped production of flawed B2 stepping chipsets and began producing B3 stepping chipsets with the silicon fix. Shipping of these new chipsets started on 14 February 2011 and Intel estimated full recovery volume in April 2011.[38] Motherboard manufacturers (such asASUS andGigabyte Technology) and computer manufacturers (such asDell andHewlett-Packard) stopped selling products that involved the flawed chipset and offered support for affected customers. Options ranged from swapping for B3 motherboards to product refunds.[39][40]
Sandy Bridge processor sales were temporarily on hold, as one cannot use the CPU without a motherboard. However, processor release dates were not affected.[41] After two weeks, Intel continued shipping some chipsets, but manufacturers had to agree to a set of terms that will prevent customers from encountering the bug.[42]
With Sandy Bridge, Intel has tied the speed of every bus (USB, SATA, PCI, PCIe, CPU cores, Uncore, memory etc.) to a single internal clock generator issuing the basic100 MHz Base Clock (BClk).[43] With CPUs being multiplier locked, the only way to overclock is to increase the BClk, which can be raised by only 5–7% without other hardware components failing. As a work around, Intel made available K/X-series processors, which feature unlocked multipliers; with a multiplier cap of 57 for Sandy Bridge.[44] For the Sandy Bridge-E platform, there is alternative method known as the BClk ratio overclock.[45]
During IDF (Intel Developer Forum) 2010, Intel demonstrated an unknown Sandy Bridge CPU running stably overclocked at 4.9 GHz on air cooling.[46][47]
Non-K edition CPUs can overclock up to four bins from its turbo multiplier.SeeLGA 1155 § Sandy Bridge family of chipsets for chipset support.
Sandy and Ivy Bridge processors withvPro capability have security features that can remotely disable a PC or erase information from hard drives. This can be useful in the case of a lost or stolen PC. The commands can be received through 3G signals, Ethernet, or Internet connections. AES encryption acceleration will be available, which can be useful for video conferencing and VoIP applications.[48][49]
Sandy and Ivy Bridge processors contain aDRM technology that some video streaming web sites rely on to restrict use of their content. Such web sites offer 1080p streaming to users with such CPUs and downgrade the quality for other users.[50]
With the introduction of the Sandy Bridge microarchitecture, Intel also introduced theIntel Data Plane Development Kit (Intel DPDK) to help developers of communications applications take advantage of the platform inpacket processing applications, andnetwork processors.[51]
Intel demonstrated theHaswell architecture in September 2011, released in 2013 as the successor toSandy Bridge andIvy Bridge.[52]
In 2015, Microsoft released a microcode update for selected Sandy Bridge and Ivy Bridge CPUs for Windows 7 and up that addresses stability issues. However, the update negatively impacts PentiumG3258 and Corei3-4010U CPU models.[53][54][55]
{{cite web}}: CS1 maint: archived copy as title (link){{cite web}}: CS1 maint: archived copy as title (link)It turns out that PCI Express 3.0 is, in fact, supported by Sandy Bridge-E (and the preview was updated to confirm 8 GT/s support the day after it went live). But because there weren't (and still aren't) any third-gen devices available yet, validating the feature was problematic. In fact, as you can see in the image below, Intel is still only officially guaranteeing that PCI Express 2.0 works, and probably will continue to do so until we see some hardware with a third-gen interface. Nevertheless, Intel's Core i7 datasheet confirms PCI Express 3.0 compliance, enabling up to 1 GB/s of bandwidth per lane, per direction.
