Core i3 processors dropped support for ECC memory in some models.Iris Graphics 550 → Iris Plus Graphics 650 (48 Execution Units, no change).Iris Graphics 540 → Iris Plus Graphics 640 (48 Execution Units, no change).HD Graphics P530 → HD Graphics P630 (24 Execution Units, no change).HD Graphics 530 → HD Graphics 630 (24 Execution Units, no change).HD Graphics 520 → HD Graphics 620 (24 Execution Units, no change).HD Graphics 515 → HD Graphics 615 (24 Execution Units, no change).HD Graphics 510 → HD Graphics 610 (12 Execution Units, no change).New native hardware support for 4K HEVC/VP9 (See § Graphics).Iris Plus now support HDMI (1.4a) 4096x2304 30 Hz (from 24 Hz).Embedded DisplayPort ( eDP) now supports eDP Standard 1.4 (From 1.3 in Skylake).Faster memory for high-perf mobile (i.e., Kaby Lake H) DDR4-2400 (from DDR4-2133).Faster memory for mainstream desktops (i.e., Kaby Lake S) DDR4-2400 (from DDR4-2133).Sunrise Point is still compatible (may need firmware update).Sunrise Point (100 series) → Union Point (200 Series).SkyLake's Speed Shift implementation is significantly improved, cutting responsiveness by as much as 66% (down to just ~10-15ms to peak frequency).10x performance/ Watt over Nehalem (Up from 8x).Enhanced "14nm+" process results in ~15% higher frequency (100 to 300 MHz increase across the board, same price).The enhanced manufacturing process allowed Kaby Lake chips to be highly overclockable with models such as the Core i7-7700K capable of comfortably reaching 5 GHz for many people with a reasonable cooling setup. Likewise, the high-end models will see very little gain. mobile) processors that will see the most substantial gain. Note that because of the improvements done to the process and the uplift in binning, it is the mostly the ultra-low power (i.e. While there is no change in pure IPC over Skylake and the actual microarchitecture is largely the same, Intel introduced a number of enhancements in Kaby Lake. )Īrchitecture See also: Skylake § Key changes from Broadwell Linux added initial support for Kaby Lake starting with Linux Kernel 4.5. Microsoft announced that only Windows 10 will have support for Kaby Lake. There are no official drivers by Intel for Windows 7 or Windows 8. ![]() Overall transistors improvement allowed for +12% drive current. These changes allowed Intel to increase the maximum frequencies of all models by around 100 to 300 megahertz which gives many single-thread applications a modest performance increase. The various enhancements improve performance without increasing the capacitance (i.e., active power characteristics). The new process has improved transistor channel strain. Intel calls the modified process "14nm+". Kaby Lake uses a modified and improved 14 nm process used for the Broadwell microarchitecture (And Skylake). ![]() See also: Broadwell § Process Technology and 14 nm lithography process Process Technology 14 nm Manufacturing Fabs On August 21 2017, Intel introduced 8th generation mobile processors ( Kaby Lake Refresh) which is also based on the same microarchitecture and doubled the cores (4 from 2) of many mainstream mobile microprocessors. The enthusiast version, Kaby Lake X, was introduced during Computex Taipei 2017. Intel released mainstream Kaby Lake S and Kaby Lake H processors on Januin time for CES 2017. Those devices are powered by Kaby Lake Y and Kaby Lake U CPUs. The first phase was announced in August of 2016 and was primarily aimed at various low-power consumer products such as light notebooks and 2-in-1s. Kaby Lake is set to be released in two phases. Workstation high-performance/dense servers Intel released Kaby Lake under 6 main brand families: Ultimate mobile performance, mobile workstationsĭesktop performance to value, AiOs, and minis Light notebooks, portable All-in-Ones (AiOs), Minis, and conference room 2-in-1s detachable, tablets, and computer sticks
