Skylake By Shabab Siddiq & Murali Srinivasan Overview ❏ Creation of Skylake ❏ Skylake Features ❏ The four Series of Skylake Processors ❏ S, Y, U, H series. ❏ Skylake Architecture ❏ Skylake vs Broadwell ❏ Skylake vs Kaby Lake 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..
