Ivy Bridge CPUs all have CPUID 0306A9h to date, and are built in four different configurations differing in the number of cores, 元 cache and GPU execution units: The later Sandy Bridge-E processors with up to eight cores and no graphics are using CPUIDs 0206D6h and 0206D7h. The stepping number cannot be seen from the CPUID but only from the PCI configuration space. Integrated graphics is now integrated on the same dieĪll Sandy Bridge processors with one, two, or four cores report the same CPUID model 0206A7h and are closely related.Intel Quick Sync Video, hardware support for video encoding and decoding.Translation lookaside buffer sizes CacheĪll translation lookaside buffers (TLBs) are 4-way associative. Larger Scheduler buffer (54-entry, up from 26-entry).Increased ROB to 168 entries (From 128).A 14- to 19-stage instruction pipeline, depending on the micro-operation cache hit or miss.This tighter integration reduces memory latency even more. In contrast, Sandy Bridge's predecessor, Clarkdale, has two separate dies (one for GMCH, one for processor) within the processor package. Integration of the GMCH (integrated graphics and memory controller) and processor into a single die inside the processor package.Up to 8 physical cores, or 16 logical cores through hyper-threading (From 6 core/12 thread).Advanced Vector Extensions (AVX) 256-bit instruction set with wider vectors, new extensible syntax and rich functionality.256-bit/cycle ring bus interconnect between cores, graphics, cache and System Agent Domain.Improved performance for transcendental mathematics, AES encryption ( AES instruction set), and SHA-1 hashing.Sandy Bridge has a single BTB that holds twice as many branch targets as the L1 and L2 BTBs in Nehalem. 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).Decoded micro-operation cache, and enlarged, optimized branch predictor.Two load/store operations per CPU cycle for each memory channel.

Improved 3 integer ALU, 2 vector ALU and 2 AGU per core.Shared 元 cache which includes the processor graphics ( LGA 1155).32 KB data + 32 KB instruction L1 cache and 256 KB L2 cache per core.DDR3\DDR3L SoDIMM (1066-1600 MHz, Ivy Bridge).Intel demonstrated a Sandy Bridge processor with A1 stepping at 2 GHz during the Intel Developer Forum in September 2009.DDR3 SoDIMM (1066-1333 MHz, Sandy Bridge) DDR3\DDR3L 1600 may work without DDR3L power optimisations and with 1333 MHz clock speed.RPGA 989 (as shown on the left) is a socket that can take Socket Socket G1 (rPGA988A) or Socket socket G2 (rPGA988B) processors. The r in rPGA refers to reduced pitch which is 1 mm × 1 mm in this socket design.

Utilization of cam-actuated retention mechanism.18 × 15 size grid removed from the center.Pins arranged in a 35 × 36 grid array (it is incompatible with G1 socket due to different placing of one pin).Supermicro, for example, produced a number of mini ITX motherboards using the QM77 chipset.

Īlthough nearly all motherboards using this socket are intended for mobile products like laptops, a few desktop boards using this do exist. Socket G2 CPUs are also known as FCPGA988 socket processors, which should be pin compatible with PPGA988. Like its predecessor, socket G1 systems, it can only run in dual-channel memory mode, but with data rates up to 1600 MHz (as opposed to the triple-channel mode which is unique to the LGA-1366 platform and subsequent Xeon sockets). It is based on Intel's Sandy Bridge architecture. Socket G2, also known as rPGA 988B is Intel's CPU socket used with their line of mobile Core i7, the successor to the Core 2 line, and also with several mobile Core i5 and Core i3 processors.
