== Development history ==
Skylake's development, as with previous processors such as [[Pentium M|Banias]], [[Dothan (microprocessor)|Dothan]], [[Conroe (microprocessor)|Conroe]], [[Sandy Bridge]], and [[Ivy Bridge (microarchitecture)|Ivy Bridge]], was primarily undertaken by Intel Israel at its engineering research center in [[Haifa|Haifa, Israel]].<ref>{{cite web|url=http://knowledge.wharton.upenn.edu/article/intel-israel-old-relationship-faces-new-criticism/|title=Intel in Israel: A Old Relationship Faces New Criticism|website=Knowledge.wharton.upenn.edu|access-date=January 24, 2018}}</ref> The final design was largely an evolution of [[Haswell (microarchitecture)|Haswell]], with minor improvements to performance and several power-saving features being added.<ref>{{cite web |url=https://arstechnica.com/information-technology/2015/08/the-many-tricks-intel-skylake-uses-to-go-faster-and-use-less-power/ |website=Ars Technica |publisher=Condé Nast |access-date=7 November 2021 |date=August 19, 2015|title=The many tricks Intel Skylake uses to go faster and use less power}}</ref> A major priority of Skylake's design was to design a microarchitecture for envelopes as low as 4.5W to embed within [[tablet computers]] and [[laptop|notebooks]] in addition to higher-power [[desktop computers]] and [[Server (computing)|servers]].<ref>[http://news.techtime.co.il/2015/09/02/intel-4/ Intel Introduced its 6th Generation Intel Core] Published September 2, 2015, techtime.co.il</ref>

In September 2014, Intel announced the Skylake microarchitecture at the [[Intel Developer Forum]] in [[San Francisco]], and that volume shipments of Skylake CPUs were scheduled for the second half of 2015.  The Skylake development platform was announced to be available in Q1 2015.  During the announcement, Intel also demonstrated two computers with desktop and mobile Skylake prototypes: the first was a desktop [[testbed]] system, running the latest version of [[3DMark]], while the second computer was a fully functional laptop, playing [[4K resolution|4K]] video.<ref>{{cite web |last=Shvets |first=Gennadiy |date=September 10, 2014 |title=Intel announces Skylake microarchitecture |url=http://www.cpu-world.com/news_2014/2014091001_Intel_announces_Skylake_microarchitecture.html |website=CPU-World |language=en-US |access-date=January 24, 2018}}</ref>

An initial batch of Skylake CPU models (i5-6600K and i7-6700K) was announced for immediate availability during the [[Gamescom]] on August 5, 2015,<ref name=launch>{{cite web|url=http://www.techpowerup.com/213616/intel-to-debut-its-core-skylake-processors-at-gamescom-2015.html|title=Intel to Debut its Core Skylake Processors at Gamescom 2015|work=TechPowerUp|date=June 19, 2015 }}</ref> unusually soon after the release of its predecessor, Broadwell, which had suffered from launch delays.<ref>{{cite web|url=http://www.valuewalk.com/2014/09/intel-corporation-launching-broadwell-skylake-chips/|title=Intel Corporation Launching Broadwell, Skylake Chips Back to Back|work=ValueWalk|date=September 16, 2014 |access-date=October 17, 2014}}</ref> Intel acknowledged in 2014 that moving from 22&nbsp;nm (Haswell) to 14&nbsp;nm (Broadwell) had been its most difficult process to develop yet, causing Broadwell's planned launch to slip by several months;<ref>{{cite web|url=http://www.anandtech.com/show/8367/intels-14nm-technology-in-detail|title=AnandTech – Intel's 14nm Technology in Detail|author=Ryan Smith|website=Anandtech.com|access-date=January 24, 2018}}</ref> yet, the 14&nbsp;nm production was back on track and in full production as of Q3 2014.<ref>{{cite web|url=http://hexus.net/tech/news/cpu/74481-intel-broadwell-skylake-client-cpus-launching-2015/|title=Intel Broadwell and Skylake client CPUs both launching in 2015|website=Hexus.net|date=September 9, 2014 |access-date=January 24, 2018}}</ref> Industry observers had initially believed that the issues affecting Broadwell would also cause Skylake to slip to 2016, but Intel was able to bring forward Skylake's release and shorten Broadwell's release cycle instead.<ref name=extremetech1>{{cite web |last=Hruska |first=Joel |date=July 14, 2014 |title=Intel's 14nm puzzle: As Skylake details leak, everybody asks – is the chip coming in 2015 or not? |url=http://www.extremetech.com/computing/186210-intels-14nm-puzzle-as-skylake-details-leak-everybody-asks-is-the-chip-coming-in-2015-or-not |work=ExtremeTech |language=en-US |access-date=October 17, 2014}}</ref><ref>{{cite web |last=Arora |first=Piyush |date=October 15, 2014 |url=http://seekingalpha.com/article/2563875-intel-skylake-development-appears-to-be-on-schedule |title=Intel: Skylake Development Appears To Be On Schedule |website=Seeking Alpha |access-date=January 24, 2018}}</ref> As a result, the Broadwell architecture had an unusually short run.<ref name=extremetech1 />

== Overclocking of unsupported processors ==
Officially Intel supported [[overclocking]] of only the K and X versions of Skylake processors. However, it was later discovered that other non-K chips could be overclocked by modifying the base clock value – a process made feasible by the base clock applying only to the CPU, RAM, and integrated graphics on Skylake. Through beta UEFI firmware updates, some motherboard vendors, such as [[ASRock]] (which prominently promoted it under the name Sky OC) allowed the base clock to be modified in this manner.<ref name=pcgamer-nonk>{{cite web |last=Porter |first=Matt |date=February 9, 2016 |title=Intel puts a stop to overclocking on non-K Skylake CPUs |url=http://www.pcgamer.com/intel-puts-a-stop-to-overclocking-on-non-k-skylake-cpus/ |website=PC Gamer |language=en-US |access-date=February 9, 2016}}</ref><ref name=hexus-nonkkod>{{cite web|title=Intel Skylake Non-K OC KOed by ASRock|url=http://hexus.net/tech/news/mainboard/90323-intel-skylake-non-k-oc-koed-asrock/ |website=Hexus |date=February 5, 2016 |access-date=February 9, 2016}}</ref>

When overclocking unsupported processors using these UEFI firmware updates, several issues arise:
<ul>
<li>C-states are disabled, therefore the CPU will constantly run at its highest frequency and voltage</li>
<li>Turbo-boost is disabled</li>
<li>Integrated graphics are disabled</li>
<li>[[AVX2]] instruction performance is poor, approximately 4-5 times slower due to the upper 128-bit half of the execution units and data buses not being taken out of their power saving states</li>
<li>CPU core temperature readings are incorrect</li>
</ul>
These issues are partly caused by the power management of the processor needing to be disabled for base clock overclocking to work.<ref name=hwbot>{{cite web|title=Non-K overclocking|url=http://wiki.hwbot.org/Skylake_overclocking#Non-K_overclocking|website=hwbot.org|access-date=May 5, 2021|archive-date=May 5, 2021|archive-url=https://web.archive.org/web/20210505135344/http://wiki.hwbot.org/Skylake_overclocking#Non-K_overclocking|url-status=dead}}</ref>

In February 2016, however, an ASRock firmware update removed the feature. On February 9, 2016, Intel announced that it would no longer allow such overclocking of non-K processors, and that it had issued a CPU [[microcode]] update that removes the function.<ref name=anand-bclk>{{cite web |last=Cutress |first=Ian |date=December 11, 2015 |title=BCLK Overclocking Intel's non-K Skylake Processors: Coming Soon |url=http://www.anandtech.com/show/9848/bclk-overclocking-intels-non-k-skylake-processors-coming-soon |website=AnandTech |language=en-US |access-date=February 9, 2016}}</ref><ref>{{cite web|title = It's official: Intel shuts down the cheap overclocking party by closing Skylake loophole|url = http://www.pcworld.com/article/3031255/hardware/its-official-intel-shuts-down-the-cheap-overclocking-party-by-closing-skylake-loophole.html|website = PCWorld|date = February 8, 2016|access-date = February 9, 2016}}</ref><ref name=pcworld-yesyoucan>{{cite web|title=Yes, you can overclock cheap Intel Skylake chips|url=http://www.pcworld.com/article/3014498/hardware/yes-you-can-overclock-cheap-intel-skylake-chips.html|website=PC World|date=December 11, 2015|access-date=February 9, 2016}}</ref> In April 2016, ASRock started selling motherboards that allow overclocking of unsupported CPUs using an external clock generator.<ref>{{cite web|url=http://www.extremetech.com/extreme/224561-new-asrock-motherboards-sport-external-clock-generators-for-intel-cpu-overclocking|title=New ASRock motherboards sport external clock generators for Intel CPU overclocking {{!}}|website=ExtremeTech|access-date=April 10, 2016}}</ref><ref>{{cite web|url=http://akiba-pc.watch.impress.co.jp/docs/news/news/20160407_752021.html|title=独自OC機能を備えたH170マザーがASRockから登場、計2モデル - AKIBA PC Hotline!|last=株式会社インプレス|website=AKIBA PC Hotline!|date=April 7, 2016|language=ja-JP|access-date=April 10, 2016}}</ref>

== Operating system support ==
In January 2016, Microsoft announced that it would end support of [[Windows 7]] and [[Windows 8.1]] on Skylake processors effective July 17, 2017; after this date, only the most critical updates for the two operating systems would be released for Skylake users if they have been judged not to affect the reliability of the OS on older hardware (until July 31, 2019; August 2019 critical update requires at least [[Windows 10]]), and Windows 10 would be the only [[Microsoft Windows]] platform officially supported on Skylake and on later Intel CPU microarchitectures beginning with Skylake's successor [[Kaby Lake]]. [[Terry Myerson]] stated that Microsoft had to make a large investment in order to reliably support Skylake on older versions of Windows, and that future generations of processors would require further investments. Microsoft also stated that due to the age of the platform, it would be challenging for newer hardware, firmware, and device driver combinations to properly run under Windows 7.<ref name=ars-skylake18months>{{cite web|title=Skylake users given 18 months to upgrade to Windows 10|url=https://arstechnica.com/information-technology/2016/01/skylake-users-given-18-months-to-upgrade-to-windows-10/|website=Ars Technica|date=January 16, 2016|access-date=January 16, 2016}}</ref><ref name=zdnet-newsupportpolicy>{{cite web|last1=Bott|first1=Ed|title=Microsoft updates support policy: New CPUs will require Windows 10|url=https://www.zdnet.com/article/microsoft-updates-support-policy-new-cpus-will-require-windows-10/|website=ZDNet.com|publisher=CBS Interactive|access-date=January 16, 2016}}</ref>

On March 18, 2016, in response to criticism over the move, primarily from enterprise customers, Microsoft announced revisions to the support policy, changing the cutoff for support and non-critical updates to July 17, 2018, and stating that Skylake users would receive all critical security updates for Windows 7 and 8.1 through the end of extended support.<ref name=ars-oemskylake>{{cite web|title=Skylake support on Windows 7 and 8.1 given a one-year extension|url=https://arstechnica.com/information-technology/2016/03/skylake-support-on-windows-7-and-8-1-given-a-one-year-extension/|website=Ars Technica|date=March 18, 2016|access-date=March 18, 2016}}</ref><ref name=cw-skylakechange>{{cite web|title=Microsoft backtracks on Windows 7 support deadline|url=http://www.computerworld.com/article/3046032/windows-pcs/microsoft-backtracks-on-windows-7-support-deadline.html|website=Computerworld.com|date=March 18, 2016|access-date=March 18, 2016}}</ref> In August 2016, citing "a strong partnership with our OEM partners and Intel", Microsoft stated that it would continue to fully support 7 and 8.1 on Skylake through the end of their respective lifecycles.<ref>{{cite web|last1=Larsen|first1=Shad|title=Updates to Silicon Support Policy for Windows|url=https://blogs.windows.com/business/2016/08/11/updates-to-silicon-support-policy-for-windows/|website=Windows business blog|publisher=Microsoft|access-date=9 May 2017|language=en|date=2016-08-11|archive-url=https://web.archive.org/web/20170425131840/https://blogs.windows.com/business/2016/08/11/updates-to-silicon-support-policy-for-windows/|archive-date=April 25, 2017|url-status=dead|df=mdy-all}}</ref><ref>{{cite news|last1=Jo Foley|first1=Mary|title=Microsoft extends again support for Windows 7, 8.1 Skylake-based devices|url=https://www.zdnet.com/article/microsoft-extends-again-support-for-windows-7-8-1-skylake-based-devices/|work=ZDNet|publisher=CBS Interactive|access-date=9 May 2017|date=2016-08-11|language=en}}</ref> In addition, an enthusiast-created [[modding|modification]] was released that disabled the [[Windows Update]] check and allowed Windows 8.1 and earlier to continue to be updated on this and later platforms.<ref name=theinquirer.net>{{cite web |url=https://www.theinquirer.net/inquirer/news/3008609/theres-a-patch-to-reinstate-windows-7-81-on-kaby-lake-cpus |title=There's a patch to reinstate Windows 7 & 8.1 on Kaby Lake CPUs |website=Theinquirer.net |access-date=January 24, 2018 |archive-url=https://web.archive.org/web/20191222033451/https://www.theinquirer.net/inquirer/news/3008609/theres-a-patch-to-reinstate-windows-7-81-on-kaby-lake-cpus |archive-date=2019-12-22 |url-status=unfit }}</ref>

Skylake's U and Y variants support one [[DIMM]] slot per channel, while H and S variants support two DIMM slots per channel.<ref name=wccftech-06-27 />  Skylake's launch and sales lifespan occur at the same time as the ongoing [[SDRAM]] market transition, with [[DDR3 SDRAM]] memory gradually being replaced by [[DDR4 SDRAM]]. Rather than working exclusively with DDR4, the Skylake microarchitecture remains [[backward compatible]] by interoperating with both types of memory. Accompanying the microarchitecture's support for both memory standards, a new SO-DIMM type capable of carrying either DDR3 or DDR4 memory chips, called [[UniDIMM]], was also announced.<ref>{{cite web

Skylake's few P variants have a reduced on-die graphics unit (12 execution units enabled instead of 24 execution units) over their direct counterparts; see the table below. In contrast, with Ivy Bridge CPUs the P suffix was used for CPUs with completely disabled on-die video chipset.

Skylake-based laptops were predicted to use wireless technology called [[Rezence (wireless charging standard)|Rezence]] for charging, and other wireless technologies for communication with peripherals. Many major PC vendors agreed to use this technology in Skylake-based laptops; however, no laptops were released with the technology as of 2019.<ref>{{cite web|url=https://www.zdnet.com/article/wire-free-pcs-tablets-and-phones-coming-in-2015-says-intel/|title=Wire-free PCs, tablets and phones coming in 2015 says Intel|date=September 10, 2014|work=ZDNet}}</ref><ref>{{cite web|url=https://www.gsmarena.com/counterclockwise_the_wireless_charging_format_wars-news-34143.php|title=Counterclockwise: the wireless charging format wars|date=November 11, 2018|work=GSMArena}}</ref>

Unlike previous generations, Skylake-based Xeon E3 no longer works with a desktop chipset that supports the same socket, and requires either the C232 or the C236 chipset to operate.

Started from Skylake, Intel had removed IDE mode (of SATA controller) and EHCI controller from its client platform chipsets.

== Known issues ==
Short loops with a specific combination of instruction use may cause unpredictable system behavior on CPUs with hyperthreading. A [[microcode]] update was issued to fix the issue.<ref>{{cite web|url=https://hothardware.com/news/critical-flaw-in-intel-skylake-and-kaby-lake-hyperthreading-discovered-requiring-bios-microcode-fix|title=[Updated] Critical Flaw In Intel Skylake And Kaby Lake HyperThreading Discovered Requiring BIOS Microcode Fix - HotHardware|website=Hothardware.com|date=June 25, 2017|access-date=January 24, 2018}}</ref>

Skylake is vulnerable to [[Spectre (security vulnerability)|Spectre]] attacks.<ref>{{cite web|url=https://lwn.net/Articles/745113/|title=Re: [RFC 09/10] x86/enter: Create macros to restrict/unrestrict Indirect Branch Speculation [LWN.net]|website=Lwn.net|access-date=January 24, 2018}}</ref>
In fact, it is more vulnerable than other processors because it uses indirect branch speculation not just on indirect branches but also when the return prediction stack underflows.

The latency for the [[spinlock]] {{code|PAUSE}} instruction has been increased dramatically (from the usual 10 cycles to 141 cycles in Skylake), which can cause performance issues with older programs or libraries using pause instructions.<ref>{{cite web |title=Why Skylake CPUs Are Sometimes 50% Slower – How Intel Has Broken Existing Code |url=https://aloiskraus.wordpress.com/2018/06/16/why-skylakex-cpus-are-sometimes-50-slower-how-intel-has-broken-existing-code/ |author=Alois Kraus |language=en |date=16 June 2018}}</ref> Intel documents the increased latency as a feature that improves power efficiency.<ref>{{cite web|url=https://www.intel.com/content/dam/www/public/us/en/documents/manuals/64-ia-32-architectures-optimization-manual.pdf|title=Intel® 64 and IA-32 Architectures Optimization Reference Manual 248966-033|date=June 2016}}</ref>

=== Server processors ===
E3 series server chips all consist of System Bus 9 GT/s, maximum memory bandwidth of 34.1 [[Gigabyte|GB]]/s dual channel memory. Unlike its predecessor, the Skylake Xeon CPUs require C230 series (C232/C236) or C240 series (C242/C246) chipset to operate, with integrated graphics working only with C236 and C246 chipsets. Mobile counterparts uses CM230 and CM240 series chipsets.
