Sandy Bridge (or Intel Q2) is the codename for Intel's 32 nm microarchitecture used in the second generation of the Intel Core processors (Core i7, i5, i3). The Sandy Bridge microarchitecture is the successor to Nehalem and Westmere microarchitecture. Intel demonstrated a Sandy Bridge processor in 2009, and released first products based on the architecture in January 2011 under the Core brand.[2][3]

Sandy Bridge is manufactured in the 32 nm process and has a soldered contact with the die and IHS (Integrated Heat Spreader), while Intel's subsequent generation Ivy Bridge uses a 22 nm die shrink and a TIM (Thermal Interface Material) between the die and the IHS.

Technology

Intel demonstrated a Sandy Bridge processor with A1 stepping at 2 GHz during the Intel Developer Forum in September 2009.[4]

Upgraded features from Nehalem include:

CPU

  • Intel Turbo Boost 2.0[5][6][7]
  • 32 KB data + 32 KB instruction L1 cache and 256 KB L2 cache per core[8]
  • Shared L3 cache which includes the processor graphics (LGA 1155)
  • 64-byte cache line size
  • New µOP cache, up to 1536-entry
  • Improved 3 integer ALU, 2 vector ALU and 2 AGU per core[9][10]
  • Two load/store operations per CPU cycle for each memory channel
  • Decoded micro-operation cache,[11] and enlarged, optimized branch predictor
  • Sandy Bridge retains the four branch predictors found in Nehalem: the branch target buffer (BTB), indirect branch target array, loop detector and renamed return stack buffer (RSB). Sandy Bridge has a single BTB that holds twice as many branch targets as the L1 and L2 BTBs in Nehalem.[12]
  • Improved performance for transcendental mathematics, AES encryption (AES instruction set), 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[13]
  • Up to 8 physical cores, or 16 logical cores through hyper-threading (From 6 core/12 thread)
  • Integration of the GMCH (integrated graphics and memory controller) and processor into a single die inside the processor package. In contrast, Sandy Bridge's predecessor, Clarkdale, has two separate dies (one for GMCH, one for processor) within the processor package. This tighter integration reduces memory latency even more.
  • A 14- to 19-stage instruction pipeline, depending on the micro-operation cache hit or miss[14]
  • Increased ROB to 168 entries (From 128)[15]
  • Larger Scheduler buffer (54-entry, up from 26-entry)
Translation lookaside buffer sizes[16][17]
Cache Page Size
Name Level 4 KB 2 MB 1 GB
DTLB 1st 64 32 4
ITLB 1st 128 8 / logical core none
STLB 2nd 512 none none
All translation lookaside buffers (TLBs) are 4-way associative.[citation needed]

GPU

  • Intel Quick Sync Video, hardware support for video encoding and decoding
  • Integrated graphics is now integrated on the same die

I/O

  • Integrated PCIe Controller

Models and steppings

All Sandy Bridge processors with one, two, or four cores report the same CPUID model 0206A7h[18] and are closely related. The stepping number cannot be seen from the CPUID but only from the PCI configuration space. The later Sandy Bridge-E processors with up to eight cores and no graphics are using CPUIDs 0206D6h and 0206D7h.[19] 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:

0206D7h C2
Sandy Bridge-EP-4 0206D6h M0 04 10 MB LGA 2011
0206D7h M1

Performance

  • The average performance increase, according to IXBT Labs and Semi Accurate as well as many other benchmarking sites, at clock to clock is 11.3% compared to the Nehalem generation, which includes Bloomfield, Clarkdale, and Lynnfield processors.[20]
  • Around twice the integrated graphics performance compared to Clarkdale's (12 EUs comparison).

List of Sandy Bridge processors

1Processors featuring Intel's HD 3000 graphics are set in bold. Other processors feature HD 2000 graphics, HD graphics (Pentium and Celeron models) or no graphics core (Graphics Clock rate indicated by N/A).

  • This list may not contain all the Sandy Bridge processors released by Intel. A more complete listing can be found on Intel's website.

Cougar Point chipset flaw

On 31 January 2011, Intel issued a recall on all 67-series motherboards due to a flaw in the Cougar Point Chipset.[31] A hardware problem exists, in which the chipset's SATA II ports may fail over time, causing failure of connection to SATA devices, though data is not at risk.[32] Intel claims that this problem will affect only 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.[33] 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.[34][35]

Sandy Bridge processor sales were temporarily on hold, as one cannot use the CPU without a motherboard. However, processor release dates were not affected.[36] 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.[37]

Limitations

Overclocking

With Sandy Bridge, Intel has tied the speed of every bus (USB, SATA, PCI, PCI-E, CPU cores, Uncore, memory etc.) to a single internal clock generator issuing the basic 100 MHz Base Clock (BClk).[38] 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.[39] For the Sandy Bridge-E platform, there is alternative method known as the BClk ratio overclock.[40]

During IDF (Intel Developer Forum) 2010, Intel demonstrated an unknown Sandy Bridge CPU running stably overclocked at 4.9 GHz on air cooling.[41][42]

Chipset

Non-K edition CPUs can overclock up to four bins from its turbo multiplier. Refer here for chipset support.

vPro remote-control

Main articles: Intel vPro and Intel Active Management Technology

Sandy and Ivy 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.[43][44]

Intel Insider

Main article: Intel Insider

Sandy and Ivy Bridge processors contain a DRM 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.[45]

Software development kit

With the introduction of the Sandy Bridge microarchitecture, Intel also introduced the Intel Data Plane Development Kit (Intel DPDK) to help developers of communications applications take advantage of the platform in packet processing applications, and network processors.[46]

Roadmap

Intel demonstrated the Haswell architecture in September 2011, released in 2013 as the successor to Sandy Bridge and Ivy Bridge.[47]

Fixes

Microsoft has released a microcode update for selected Sandy Bridge and Ivy Bridge CPUs for Windows 7 and up that addresses stability issues. The update, however, negatively impacts Intel G3258 and 4010U CPU models.[48][49][50]

Trivia

Contains uROM implementation of Eight queens puzzle, supporting up-to 20x20, 76*2 bytes ROM, 83*4 bytes data, 185us for all 92 solutions of 8x8 board, 15.24sec for 15x15.
