History
Predecessor Broadwell (tick/process)
Successor

Skylake [6] [7] is the codename used by Intel for a processor microarchitecture that was launched in August 2015 [8] succeeding the Broadwell microarchitecture. [9] Skylake is a microarchitecture redesign using the same 14 nm manufacturing process technology [10] as its predecessor, serving as a "tock" in Intel's "tick–tock" manufacturing and design model. According to Intel, the redesign brings greater CPU and GPU performance and reduced power consumption. Skylake CPUs share their microarchitecture with Kaby Lake, Coffee Lake, Cannon Lake, Whiskey Lake, and Comet Lake CPUs.

Contents

Skylake is the last Intel platform on which Windows earlier than Windows 10 will be officially supported by Microsoft, [11] although enthusiast-created modifications exist that allow Windows 8.1 and earlier to continue to receive Windows Updates on later platforms. [12] [13] [14]

Some of the processors based on the Skylake microarchitecture are marketed as "6th-generation Core". [15] [16] [17]

Intel officially declared end of life and discontinued Skylake LGA 1151 CPUs on March 4, 2019. [18]

Development history

Skylake's development, as with processors such as Banias, Dothan, Conroe, Sandy Bridge and Ivy Bridge, was primarily undertaken by Intel Israel [19] at its engineering research center in Haifa, Israel. The Haifa development team worked on the project for four years, and faced many challenges: "But by re-writing the microarchitecture and developing new concepts such as the Speed Shift Technology, we created a processor for 4.5 W to 45 W mobile devices, and up to 91 W for desktop devices." [20] The Skylake processors are used to power a wide range of devices, from fanless laptops, all the way to desktops. [21] "Because of Skylake's features, companies will be able to release laptop PCs that are half as thick and half as heavy as those from five years ago," according to Intel. [22]

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. Also, 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 video. [23]

An initial batch of Skylake CPU models (6600K and 6700K) was announced for immediate availability during the Gamescom on August 5, 2015, [24] unusually soon after the release of its predecessor, Broadwell, which had suffered from launch delays. [25] Intel acknowledged in 2014 that moving from 22 nm (Haswell) to 14 nm (Broadwell) had been its most difficult process to develop yet, causing Broadwell's planned launch to slip by several months; [26] yet, the 14 nm production was back on track and in full production as of Q3 2014. [27] 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. [28] [29] As a result, the Broadwell architecture had an unusually short run. [28]

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. [30] [31]

When overclocking unsupported processors using these UEFI firmware updates, several issues arise:

These issues are partly caused by the power management of the processor needing to be disabled for base clock overclocking to work. [32]

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. [33] [34] [35] In April 2016, ASRock started selling motherboards that allow overclocking of unsupported CPUs using an external clock generator. [36] [37]

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, and Windows 10 would be the only Microsoft Windows platform officially supported on Skylake, as well as all future 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. [38] [39]

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. [40] [41] 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. [42] [43] In addition, an enthusiast-created 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. [44]

As of Linux kernel 4.10, Skylake mobile power management is in reasonably good shape with most Package C states supported seeing some use. If this is not the case, then the cause is likely bugs in the system firmware of the particular computer, which might be resolved by updating the BIOS. The user can easily optimize power management beyond the Linux default settings with the PowerTOP utility; for those who use Lennart Poettering's systemd, PowerTOP provides a service which will start up with the computer and auto-tune various settings to reduce power usage. [45] Linux 4.11 enables Frame-Buffer Compression for the integrated graphics chipset by default, which lowers power consumption. [46] Battery runtime should be similar to Windows 10 and possibly better, but further improvements can still be made.

Skylake is fully supported on OpenBSD 6.2 and later, including accelerated graphics. [47]

Like its predecessor, Broadwell, Skylake is available in five variants, identified by the suffixes "S" (SKL-S), "X" (SKL-X), "H" (SKL-H), "U" (SKL-U), and "Y" (SKL-Y). SKL-S and SKL-X contain overclockable "K" and "X" variants with unlocked multipliers. [48] The H, U and Y variants are manufactured in ball grid array (BGA) packaging, while the S and X variants are manufactured in land grid array (LGA) packaging using a new socket, LGA 1151 (LGA 2066 for Skylake X). [49] Skylake is used in conjunction with Intel 100 Series chipsets, also known as Sunrise Point. [50]

The major changes between the Haswell and Skylake architectures include the removal of the fully integrated voltage regulator (FIVR) introduced with Haswell. [51] On the variants that will use a discrete Platform Controller Hub (PCH), Direct Media Interface (DMI) 2.0 is replaced by DMI 3.0, which allows speeds of up to 8  GT/s.

Skylake's U and Y variants support one DIMM slot per channel, while H and S variants support two DIMM slots per channel. [49] 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 memory. 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. [52]

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.

Other enhancements include Thunderbolt 3.0, SATA Express, Iris Pro graphics with Direct3D feature level  12_1 with up to 128 MB of L4 eDRAM cache on certain SKUs. [53] The Skylake line of processors retires VGA support, [54] while supporting up to five monitors connected via HDMI 1.4, DisplayPort 1.2 or Embedded DisplayPort (eDP) interfaces. [55] HDMI 2.0 (4K@60 Hz) is only supported on motherboards equipped with Intel's Alpine Ridge Thunderbolt controller. [56]

The Skylake instruction set changes include Intel MPX (Memory Protection Extensions) and Intel SGX (Software Guard Extensions). Future Xeon variants will also have Advanced Vector Extensions 3.2 ("AVX-512F"). [2] [3]

Skylake-based laptops were predicted to use wireless technology called 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. [57] [58]

The integrated GPU of Skylake's S variant supports on Windows DirectX  12 Feature Level 12_1, OpenGL  4.6 with latest Windows 10 driver update [59] (OpenGL 4.5 on Linux [60] ) and OpenCL  3.0 standards, as well as some modern hardware video encoding/decoding formats such as VP9 (GPU accelerated decode only), VP8 and HEVC (hardware accelerated 8-bit encode/decode and GPU accelerated 10-bit decode). [61] [62]

Intel also released unlocked (capable of overclocking) mobile Skylake CPUs. [63]

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.

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. [64]

Skylake is vulnerable to Spectre attacks. [65] 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 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. [66] Intel documents the increased latency as a feature that improves power efficiency. [67]

Xeon Line of Intel server processors

Xeon is a brand of x86 microprocessors designed, manufactured, and marketed by Intel, targeted at the non-consumer workstation, server, and embedded system markets. It was introduced in June 1998. Xeon processors are based on the same architecture as regular desktop-grade CPUs, but have advanced features such as support for ECC memory, higher core counts, more PCI Express lanes, support for larger amounts of RAM, larger cache memory and extra provision for enterprise-grade reliability, availability and serviceability (RAS) features responsible for handling hardware exceptions through the Machine Check Architecture. They are often capable of safely continuing execution where a normal processor cannot due to these extra RAS features, depending on the type and severity of the machine-check exception (MCE). Some also support multi-socket systems with two, four, or eight sockets through use of the Quick Path Interconnect (QPI) bus.

Land grid array Type of surface-mount packaging for integrated circuits

The land grid array (LGA) is a type of surface-mount packaging for integrated circuits (ICs) that is notable for having the pins on the socket rather than the integrated circuit. An LGA can be electrically connected to a printed circuit board (PCB) either by the use of a socket or by soldering directly to the board.

The Intel Core microarchitecture is a multi-core processor microarchitecture unveiled by Intel in Q1 2006. It is based on the Yonah processor design and can be considered an iteration of the P6 microarchitecture introduced in 1995 with Pentium Pro. High power consumption and heat intensity, the resulting inability to effectively increase clock rate, and other shortcomings such as an inefficient pipeline were the primary reasons why Intel abandoned the NetBurst microarchitecture and switched to a different architectural design, delivering high efficiency through a small pipeline rather than high clock rates. The Core microarchitecture initially did not reach the clock rates of the NetBurst microarchitecture, even after moving to 45 nm lithography. However after many generations of successor microarchitectures which used Core as their basis, Intel managed to eventually surpass the clock rates of Netburst with the Devil's Canyon microarchitecture reaching a base frequency of 4 GHz and a maximum tested frequency of 4.4 GHz using 22 nm lithography.

Platform Controller Hub

The Platform Controller Hub (PCH) is a family of Intel's single-chip chipsets, first introduced in 2009. It is the successor to the Intel Hub Architecture, which used two chips - a northbridge and southbridge instead, and first appeared in the Intel 5 Series.

Haswell (microarchitecture) Intel processor microarchitecture

Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge. Intel officially announced CPUs based on this microarchitecture on June 4, 2013, at Computex Taipei 2013, while a working Haswell chip was demonstrated at the 2011 Intel Developer Forum. With Haswell, which uses a 22 nm process, Intel also introduced low-power processors designed for convertible or "hybrid" ultrabooks, designated by the "U" suffix.

LGA 1156 Intel desktop CPU socket

LGA 1156, also known as Socket H or H1, is an Intel desktop CPU socket. Its incompatible successor is LGA 1155.

Intel Core Mid-range to high-end central processing units

Intel Core are streamlined midrange consumer, workstation and enthusiast computers central processing units (CPU) marketed by Intel Corporation. These processors displaced the existing mid- to high-end Pentium processors at the time of their introduction, moving the Pentium to the entry level. Identical or more capable versions of Core processors are also sold as Xeon processors for the server and workstation markets.

LGA 2011

LGA 2011, also called Socket R, is a CPU socket by Intel. Released on November 14, 2011, it replaces Intel's LGA 1366 and LGA 1567 in the performance and high-end desktop and server platforms. The socket has 2011 protruding pins that touch contact points on the underside of the processor.

LGA 1150 Intel motherboard socket for Haswell CPUs

LGA 1150, also known as Socket H3, is a microprocessor socket used by Intel's central processing units (CPUs) built on the Haswell microarchitecture. This socket is also used by the Haswell's successor, Broadwell microarchitecture.

Ivy Bridge (microarchitecture)

Ivy Bridge is the codename for the "third generation" of the Intel Core processors. Ivy Bridge is a die shrink to 22 nanometer manufacturing process based on the 32 nanometer Sandy Bridge —see tick–tock model. The name is also applied more broadly to the 22 nm die shrink of the Sandy Bridge microarchitecture based on FinFET ("3D") Tri-Gate transistors, which is also used in the Xeon and Core i7 Ivy Bridge-EX (Ivytown), Ivy Bridge-EP and Ivy Bridge-E microprocessors released in 2013.

Broadwell (microarchitecture) Fifth model generation of Intel Processor

Broadwell is the fifth generation of the Intel Core Processor. It's Intel's codename for the 14 nanometer die shrink of its Haswell microarchitecture. It is a "tick" in Intel's tick–tock principle as the next step in semiconductor fabrication. Like some of the previous tick-tock iterations, Broadwell did not completely replace the full range of CPUs from the previous microarchitecture (Haswell), as there were no low-end desktop CPUs based on Broadwell.

LGA 1151 Intel microprocessor compatible socket

LGA 1151, also known as Socket H4, is an Intel microprocessor compatible socket which comes in two distinct versions: the first revision which supports both Intel's Skylake and Kaby Lake CPUs, and the second revision which supports Coffee Lake CPUs exclusively.

Intel X99, codenamed "Wellsburg", is a Platform Controller Hub (PCH) designed and manufactured by Intel, targeted at the high-end desktop (HEDT) and enthusiast segments of the Intel product lineup. The X99 chipset supports both Intel Core i7 Extreme and Intel Xeon E5-16xx v3 and E5-26xx v3 processors, which belong to the Haswell-E and Haswell-EP variants of the Haswell microarchitecture, respectively. All supported processors use the LGA 2011-v3 socket.

Kaby Lake is Intel's codename for its seventh generation Core microprocessor family announced on August 30, 2016. Like the preceding Skylake, Kaby Lake is produced using a 14 nanometer manufacturing process technology. Breaking with Intel's previous "tick–tock" manufacturing and design model, Kaby Lake represents the optimized step of the newer process–architecture–optimization model. Kaby Lake began shipping to manufacturers and OEMs in the second quarter of 2016, and mobile chips have started shipping while Kaby Lake (desktop) chips were officially launched in January 2017.

Coffee Lake Eighth-generation Intel Core microprocessor family

Coffee Lake is Intel's codename for its eighth generation Core microprocessor family, announced on September 25, 2017. It is manufactured using Intel's second 14 nm process node refinement. Desktop Coffee Lake processors introduced i5 and i7 CPUs featuring six cores and Core i3 CPUs with four cores and no hyperthreading.

LGA 2066

LGA 2066, also called Socket R4, is a CPU socket by Intel that debuted with Skylake-X and Kaby Lake-X processors in June 2017. It replaces Intel's LGA 2011-3 (R3) in the performance, high-end desktop and Workstation platforms, while LGA 3647 replaces LGA 2011-3 (R3) in the server platforms based on Skylake-SP.

LGA 1200

LGA 1200 is an Intel microprocessor compatible socket for Comet Lake and Rocket Lake desktop CPUs which was released in Q2 2020.

Rocket Lake is Intel's codename for its 11th generation Core microprocessors. Released on March 30, 2021, it is based on the new Cypress Cove microarchitecture, a variant of Sunny Cove backported to Intel's 14 nm process node. Rocket Lake cores contain significantly more transistors than current Skylake-derived Comet Lake cores.
