The Intel Management Engine (ME), also known as the Intel Manageability Engine, [1] [2] is an autonomous subsystem that has been incorporated in virtually all of Intel's processor chipsets since 2008. [1] [3] [4] It is located in the Platform Controller Hub of modern Intel motherboards.
Sandy Bridge 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 .
Sandy Bridge 32 nm microarchitecture, released January 9, 2011. Formerly called Gesher but renamed in 2007. [2] First x86 to introduce 256 bit AVX instruction set and implementation of YMM registers. Ivy Bridge: successor to Sandy Bridge, using 22 nm process, released in April 2012. Haswell 22 nm microarchitecture, released June 3, 2013.
Die shrink of Sandy Bridge from 32 nm to 22 nm, with minor architectural improvements and faster graphics. First product to use Intel's tri-gate transistors. Abbreviated IVB. [26] Reference Possibly Pontivy, Brittany, France. 2012 Jaketown CPU Xeon E5-2600 series CPUs, aimed at dual-socket servers. Also code-named Sandy Bridge-EP.
3 For Sandy Bridge enthusiast desktop platform. Sandy Bridge CPUs will provide up to 40 PCIe 3.0 lanes for direct GPU connectivity and additional 4 PCIe 2.0 lanes. NOTE : This reference number 4 is on X79, which is a Sandy bridge -E, not Sandy Bridge, and PCIe 3.0 only is enabled when an Ivy Bridge-E CPU or Xeon E-5 series is used.
Integrated Management Engine with its own 100 Mbit/s Ethernet [28] 5520: Tylersburg-36S, Tylersburg-36D 1, 2 4.8, 5.86 or 6.4 GT/s 2 ×16 PCIe Gen 2, 1 ×4 PCIe Gen 1 to talk to southbridge ICH10 (ICH9 also possible) Integrated Management Engine with its own 100 Mbit/s Ethernet [28]
Based on Sandy Bridge microarchitecture.; All models support: MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, Enhanced Intel SpeedStep Technology (EIST), Intel 64, XD bit (an NX bit implementation), TXT, Intel VT-x, Intel EPT, Intel VT-d, Intel VT-c, [1] Intel x8 SDDC, [3] Hyper-threading (except E5-1603, E5-1607, E5-2603, E5-2609 and E5-4617), Turbo Boost (except E5-1603, E5-1607, E5-2603 ...
The Intel Management Engine was also moved to the PCH starting with the Nehalem processors and 5-Series chipsets. AMD's chipsets instead use several PCIe lanes to connect with the CPU while also providing their own PCIe lanes, which are also provided by the processor itself. [3] [4] The chipset also contains the Nonvolatile BIOS memory.
