24-458: Ivy Bridge is the codename for Intel's 22 nm microarchitecture used in the third generation of the Intel Core processors ( Core i7 , i5 , i3 ). Ivy Bridge is a die shrink to 22 nm process based on FinFET ("3D") Tri-Gate transistors , from the former generation's 32 nm Sandy Bridge microarchitecture—also known as tick–tock model . The name is also applied more broadly to
48-467: A CPU is overclocked , even at default voltage setting. Impress PC Watch, a Japanese website, performed experiments that confirmed earlier speculations that this is because Intel used a poor quality (and perhaps lower cost) thermal interface material (thermal paste, or "TIM") between the chip and the heat spreader , instead of the fluxless solder of previous generations. The mobile Ivy Bridge processors are not affected by this issue because they do not use
72-704: A brief explanation of their meaning and their likely namesake, and the year of their earliest known public appearance. Most processors after a certain date were named after cities that could be found on a map of the United States. This was done for trademark considerations. Banias was the last of the non-US city names. Gesher was renamed to Sandy Bridge to comply with the new rule. Dothan is a city both in Israel and in Alabama. Could be named after Yonah,IN LGA 2011-1 LGA 2011 , also called Socket R ,
96-467: A heat spreader between the chip and cooling system. Socket 2011 Ivy Bridge processors continue to use the solder. Enthusiast reports describe the TIM used by Intel as low-quality, and not up to par for a "premium" CPU, with some speculation that this is by design to encourage sales of prior processors. Further analyses caution that the processor can be damaged or void its warranty if home users attempt to remedy
120-475: A maximum of 6 cores. Both Core-i7 and Xeon versions are produced: the Xeon versions marketed as Xeon E5-1400 v2 act as drop-in replacements for the existing Sandy Bridge-EN based Xeon E5, Xeon E5-2600 V2 versions act as drop-in replacements for the existing Sandy Bridge-EP based Xeon E5, while Core-i7 versions designated i7-4820K, i7-4930K and i7-4960X were released on September 10, 2013, remaining compatible with
144-448: Is a CPU socket by Intel released on November 14, 2011. It launched along with LGA 1356 to replace its predecessor, LGA 1366 (Socket B) and LGA 1567 . While LGA 1356 was designed for dual-processor or low-end servers, LGA 2011 was designed for high-end desktops and high-performance servers. The socket has 2011 protruding pins that touch contact points on the underside of the processor. The LGA 2011 socket uses QPI to connect
168-575: Is another updated generation of the socket, used for Haswell-E and Haswell-EP CPUs and Broadwell-E, which were released in August and September 2014, respectively. Updated socket generations are physically similar to LGA 2011. Still, different electrical signals, keying of the Independent Loading Mechanism (ILM) and integrating DDR4 memory controller rather than DDR3 prevent backward compatibility with older CPUs. In
192-505: Is expected to result in higher temperatures when the CPU is overclocked; Intel also stated that this is as expected and will likely not improve in future revisions. All Ivy Bridge processors with one, two, or four cores report the same CPUID model 0x000306A9, and are built in four different configurations differing in the number of cores, L3 cache and GPU execution units. Intel Ivy Bridge–based Xeon microprocessors (also known as Ivy Bridge-E )
216-952: 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. Additional high-end server processors based on the Ivy Bridge architecture, code named Ivytown, were announced September 10, 2013 at the Intel Developer Forum , after the usual one year interval between consumer and server product releases. The Ivy Bridge-EP processor line announced in September 2013 has up to 12 cores and 30 MB third level cache, with rumors of Ivy Bridge-EX up to 15 cores and an increased third level cache of up to 37.5 MB, although an early leaked lineup of Ivy Bridge-E included processors with
240-498: Is the standard type, while the narrow one is alternatively available for space-constrained applications. A matching heatsink is required for each ILM type. Information for the Intel X79 (for desktop) and C600 series (for workstations and servers, codenamed Romley ) chipsets is in the table below. The Romley (EP) platform was delayed approximately one quarter, allegedly due to a SAS controller bug. The X79 appears to contain
264-703: Is used by Sandy Bridge-E /EP and Ivy Bridge-E /EP processors with the corresponding X79 (E – enthusiast class) and C600-series (EP – Xeon class) chipsets. It and LGA 1155 are the two last Intel sockets to support Windows XP and Windows Server 2003 . LGA 2011-1 (Socket R2), an updated generation of the socket and the successor of LGA 1567 , is used for Ivy Bridge-EX ( Xeon E7 v2 ), Haswell-EX ( Xeon E7 v3 ) and Broadwell-EX (Xeon E7 v4) CPUs, which were released in February 2014, May 2015 and July 2016, respectively.
