Sandy Bridge, Nehalem's successor, is the codename for a processor microarchitecture developed by Intel at Intel Israel Development Center[1] beginning in 2005 targeting the 32 nm process. The codename was previously "Gesher" (meaning "bridge" in Hebrew).[2] Sandy Bridge processors were first released on January 9, 2011. Intel demoed a Sandy Bridge processor with A1 stepping at 2 GHz during the Intel Developer Forum in 2009.[3]
The yet-to-be released 22 nm die shrink of Sandy Bridge has the codename Ivy Bridge.[4][5]
Technology
- 32 kB data + 32 kB instruction L1 cache (3 clocks) and 256 kB L2 cache (8 clocks) per core
- Shared L3 cache includes the processor graphics (LGA 1155)
- 64-byte cache line size
- Two load/store operations per cycle for each memory channel
- Decoded micro-op cache and enlarged, optimized branch predictor
- Improved performance for transcendental mathematics, AES encryption, and SHA-1 hashing
- 256-bit/cycle ring bus interconnect between cores, graphics, cache and System Agent Domain
- Advanced Vector Extensions (AVX) 256-bit instruction set with wider vectors, new extensible syntax, and rich functionality
- Intel Quick Sync Video, hardware support for video encoding and decoding
- Hyper-threading in selected models
Ivy Bridge
Ivy Bridge is the codename for the yet-to-be released 22 nm die shrink of Sandy Bridge. Ivy Bridge processors will be backwards-compatible with the Sandy Bridge platform.[6] According to a leaked Intel roadmap, Ivy Bridge processors will be released in March-April 2012.[7] Another source specified that the Ivy Bridge platform would be released in March 2012, with the notebook models appearing in April 2012.[8] TDP ranges in the usual 95/65/45/35W options for desktop processors[9], while Intel says that mobile processors will get a "variable TDP" with for example a 15W TDP when a laptop is mobile, which automatically rises to 35W TDP when the laptop is plugged into a docking bay (with a corresponding rise in performance).[10]
Expected Ivy Bridge feature improvements from Sandy Bridge:
- Intel's tri-gate transistor technology, which will significantly reduce power consumption[11]
- PCI Express 3.0 support[12]
- Next Generation Intel HD Graphics with DirectX 11, OpenGL 3.1 and OpenCL 1.1 support. The built-in GPU is believed to have up to 16 execution units (EUs), compared to Sandy Bridge's maximum of 12.[13]
- Next Generation Intel Quick Sync Video[13]
- The new random number generator and the RdRand instruction[14] which is codenamed Bull Mountain.[15]
While Ivy Bridge will be compatible with the Cougar Point chipset motherboards associated with Sandy bridge, Intel will also release a new 7-series Panther Point chipset with Ivy bridge. This chipset will have integrated USB 3.0[16]
Performance
Sandy Bridge
- Up to 17% more CPU performance clock-for-clock compared to Lynnfield processors[17]
- Around twice the integrated graphics performance compared to Clarkdale's (12 EUs comparison).
Ivy Bridge
Intel's performance targets (compared to Sandy Bridge):[18]
- 20% increase in CPU performance.
- 30% increase in integrated graphics performance.

Cougar Point chipset flaw
On January 31, 2011, Intel issued a recall on all 67-series motherboards due to a flaw in the Cougar Point Chipset.[24] A hardware issue, in which the chipset's SATA-II ports may fail over time, cause failure of connection to SATA-II devices, though data is not at risk.[25] Intel claims that this problem will only affect 5% of users over 3 years however heavier I/O workloads can exacerbate the problem.
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.[26] Motherboard manufacturers (such as ASUS and Gigabyte Technology) and computer manufacturers (such as Dell and Hewlett-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.[27][28]
Sandy Bridge processor sales were temporarily on hold, as one cannot use the CPU without a motherboard. However, processor release dates are not affected.[29] After two weeks, Intel has continued shipping some chipsets, but manufacturers have to agree to a set of terms that will prevent customers from encountering the bug.[30]
Limitations
Overclocking
Due to a single clock generator controlling the speed of all electrical buses, overclocking of LGA-1155 compatible processors beyond the default 100 MHz base clock speed is very limited, up to 5-7% without other hardware components failing.[31] However, Intel has made available K-edition processors which feature unlocked multipliers; the highest multiplier for Sandy Bridge is 57.[32]
Intel has demonstrated a Sandy Bridge CPU running stably overclocked at 4.9 GHz on air cooling.[33][34]
Intel Sandy Bridge E-series Processors will come with "Performance OverClocking" support.[35]
Chipset
Non-K edition CPUs can overclock up to four bins from its turbo multiplier. Refer here for chipset support.
Intel Insider and remote-control
The processors include a "service" called Intel Insider, which the company claims is "an extra layer of content protection",[36] and despite claims, is a form of hardware restrictions and Digital rights management (a technology that inhibits uses of digital content not desired or intended by the content provider). This protection technology is only intended for streaming services at the moment.
Sandy Bridge processors with Vpro 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.[37]
Successor
The Haswell microarchitecture will be the successor to the Sandy Bridge and Ivy Bridge architectures.
