15-452: 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

30-467: 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

45-666: 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 Intel Developer Forum To emphasize

60-464: 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

75-471: 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

90-502: 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 )

105-929: 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

120-573: The Haswell architecture in September 2011, which began release in 2013 as the successor to Sandy Bridge and Ivy Bridge. 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. List of Intel codenames Intel has historically named integrated circuit (IC) development projects after geographical names of towns, rivers or mountains near

135-903: The X79 and LGA 2011 hardware. For the intermediate LGA 1356 socket, Intel launched the Xeon E5-2400 v2 (codenamed Ivy Bridge-EN) series in January 2014. These have up to 10 cores. A new Ivy Bridge-EX line marketed as Xeon E7 v2 had no corresponding predecessor using the Sandy Bridge microarchitecture but instead followed the older Westmere-EX processors. Processors featuring Intel's HD 4000 graphics (or HD P4000 for Xeon) are set in bold . Other processors feature HD 2500 graphics or HD Graphics unless indicated by N/A. List of announced desktop processors, as follows: Suffixes to denote: Suffixes to denote: Suffixes to denote: Intel demonstrated

150-530: The Xeon and Core i7 Extreme Ivy Bridge-E series of processors released in 2013. Ivy Bridge processors are backward compatible with the Sandy ;Bridge platform, but such systems might require a firmware update (vendor specific). In 2011, Intel released the 7-series Panther Point chipsets with integrated USB 3.0 and SATA 3.0 to complement Ivy Bridge. Volume production of Ivy Bridge chips began in

165-660: The earliest Intel microarchitecture to officially support Windows 10 64-bit (NT 10.0). The Ivy Bridge CPU microarchitecture is a shrink from Sandy Bridge and remains largely unchanged. Like its predecessor, Sandy Bridge, Ivy Bridge was also primarily developed by Intel's Israel branch, located in Haifa, Israel . Notable improvements include: The mobile and desktop Ivy Bridge chips also include some minor yet notable changes over Sandy Bridge: Compared to its predecessor, Sandy Bridge: Ivy Bridge's temperatures are reportedly 10   °C higher compared to Sandy Bridge when

180-727: The importance of China , the Spring 2007 IDF was held in Beijing instead of San Francisco , and San Francisco and Taipei shared the Fall IDF event in September and October, respectively. Three IDF shows were scheduled in 2008; with the date of IDF San Francisco notably moving to August rather than September. In previous years, events were held in major cities around the world such as San Francisco, Mumbai , Bangalore , Moscow , Cairo , São Paulo , Amsterdam , Munich and Tokyo . On April 17, 2017, Intel announced that it would no longer be hosting IDF. As

195-619: The location of the Intel facility responsible for the IC. Many of these are in the American West, particularly in Oregon (where most of Intel's CPU projects are designed; see famous codenames ). As Intel's development activities have expanded, this nomenclature has expanded to Israel and India , and some older codenames refer to celestial bodies . The following table lists known Intel codenames along with

210-414: The matter. The TIM has much lower thermal conductivity , causing heat to trap on the die. Experiments with replacing this TIM with a higher-quality one or other heat removal methods showed a substantial temperature drop, and improvements to the increased voltages and overclocking sustainable by Ivy Bridge chips. Intel claims that the smaller die of Ivy Bridge and the related increase in thermal density

225-404: The third quarter of 2011. Quad-core and dual-core-mobile models launched on April 29, 2012 and May 31, 2012 respectively. Core i3 desktop processors, as well as the first 22 nm Pentium , were announced and available the first week of September 2012. Ivy Bridge is the final Intel platform on which versions of Windows prior to Windows 7 are officially supported by Microsoft. It is also
