Creation of Skylake➔ Skylake was primarily developed in Intel Israel.➔ They rewrote the microarchitecture and developed “speed shift
technology” to create a processor for 4.5-45W mobile devices and 91W desktops.
➔ Skylake processors were developed to cover a wide range of devices.
Skylake Features➔ The Skylake enhancements such as thunderbolt 3.0, SATA express, Iris Pro
graphics with Direct3D with up to 128MB of eDRAM cache on certain SKU’s.
➔ The skylake processors retire VGA support.➔ Instead the processors support up to five monitors connected via HDMI
1.4, DisplayPort 1.2 or Embedded DisplayPort(eDP) interfaces.➔ Skylake-based laptops may use wireless technology called Renzence for
charging.
Skylake Features➔ The integrated GPU of the S series also supports DirectX 12, as well as
some modern hardware video encoding/decoding. ➔ Initially Intel had it so only the K variant of the S series could be
overclockable, but it was found that by changing the base clock value other non “K” chips could be overclockable.
➔ An asrock firmware update removed on February 2016.
Skylake Architecture
The Four Series of Skylake Processors➔ The Skylake processors, are available in four different series like its
predecessor Broadwell: the Y, U H, and S series.➔ The Y series is specifically used for tablets and compute sticks.➔ The U series is used for notebooks and portable 2 in 1’s.➔ H series is used in gaming notebooks as well as mobile devices.➔ The S series is used for desktops.
The S and H Series of Skylake➔ The S series of Skylake
has a K variant that is overclockable and also has unlocked multipliers.
➔ The S and H series both contain two dual in-line memory modules.
➔ The S series was specifically created with land grid array packaging which used a newer socket at the time.
The U and Y Series of Skylake➔ The U and Y series are both
made manufactured in a ball grid array.
➔ The U and Y series contains one dual in line memory module.
➔ Requires lower power consumption.
Skylake vs Broadwell➔ The main difference between Broadwell and Skylake is that the fully
integrated voltage regulator (FIVR) was removed.➔ Broadwell is the ‘tick’ for the 14nm technology in Intel’s ‘tick-tock’ model.
Skylake is the ‘tock’.➔ Skylake upgrades the digital media
Interface 2.0 to 3.0 to allow up to 8 GT/s speeds.
Skylake vs Kaby Lake➔ By the time Kaby Lake starts intel will move away from their tick tock
process to a process, architecture, optimization process technology.➔ Kaby Lake will be a “semi - tock” update meaning it is just slight upgrades
to what skylake already has. ➔ Kaby lake will feature USB 3.1 support and a new graphics architecture to
improve performance in 3D graphics and 4k video playback.
Skylake vs Kaby Lake (continued)➔ Kaby Lake Will only support Windows 10➔ Kaby Lake will also support Intel’s Optane storage technology (faster
SSDs)➔ Kaby Lake has mostly architecture changes from skylake such as moving
to the 200 series chipset(Union Point) from the 100 series chipset(Sunrise Point), thermal design power up to 95W.
