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 basic 100 MHz Base Clock (BClk). [44] 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 ...
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.
Intel Ivy Bridge–based Xeon microprocessors (also known as Ivy Bridge-E) is the follow-up to Sandy Bridge-E, using the same CPU core as the Ivy Bridge processor, but in LGA 2011, LGA 1356 and LGA 2011-1 packages for workstations and servers. There are five different families of Xeon processors that were based on Sandy Bridge architecture:
Being a synchronous circuit the QPI operates at a clock rate of 2.4 GHz, 2.93 GHz, 3.2 GHz, 3.6 GHz, 4.0 GHz or 4.8 GHz (3.6 GHz and 4.0 GHz frequencies were introduced with the Sandy Bridge-E/EP platform and 4.8 GHz with the Haswell-E/EP platform). The clock rate for a particular link depends on the capabilities of the components at each end ...
Xeon E3-12xx v2 is a minor update of the Sandy Bridge-based E3-12xx, using the 22 nm shrink, and providing slightly better performance while remaining backwards compatible. They were released in May 2012 and mirror the desktop Core i3/i5/i7-3xxx parts.
Like its predecessor, Sandy Bridge, Ivy Bridge was also primarily developed by Intel's Israel branch, located in Haifa, Israel. [8] Notable improvements include: [ 9 ] [ 10 ] New 22 nm Tri-gate transistor ("3-D") technology offer as much as a 50% reduction to power consumption at the same performance level as compared to 2-D planar transistors ...
Sandy Bridge-EP branded as Xeon E5 models aimed at high-end servers and workstations. It supported motherboards equipped with up to 4 sockets. Sandy Bridge-EN uses a smaller socket for low-end and dual-processor servers on certain Xeon E5 and Pentium branded models. Sandy Bridge Xeon were mostly identical to its desktop counterparts apart from ...
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 ...
