Kaby Lake was announced on 30 August 2016.[1] Like Skylake, Kaby Lake is 14 nanometer. Kaby Lake began shipping to manufacturers and OEMs in the second quarter of 2016,[2][3] and mobile chips have started shipping[4] with more of Kaby Lake (desktop) chips to be released in the coming months or early next year (2017).

Skylake was anticipated to be succeeded by the 10 nanometer Cannonlake, but it was announced on 16 July 2015, that Cannonlake has been delayed until the second half of 2017.[5][6]

Features

Built on an improved 14 nm process (14FF+), Kaby Lake features faster CPU clock speeds, clock speed changes, and higher Turbo frequencies. Beyond these process and clock speed changes, little of the CPU architecture has changed from Skylake.[7] Skylake and Kaby Lake have the same IPC (performance per MHz).[1] Kaby Lake adds native USB 3.1 Generation 2 (10 Gbit/s) support, but without a 200 series Union Point chipset, a third-party add-on chip is necessary in order to provide USB 3.1 (10 Gbit/s) ports.[8]

Kaby Lake features a new graphics architecture to improve performance in 3D graphics and 4K video playback.[1][9] It will add native HDCP 2.2 support,[10] along with fixed function decode of H.264, HEVC Main and Main10/10-bit, and VP9 10-bit and 8-bit video.[7][11][12][13] Hardware encode is supported for H.264, HEVC Main10/10-bit, and VP9 8-bit video. VP9 10-bit encode is not supported in hardware.

Architecture changes compared to Skylake

Kaby Lake features the same CPU core and performance per MHz as Skylake. Features specific to Kaby Lake include:

Compatibility

While Skylake and Kaby Lake CPUs are fully compatible with most existing x86/x86-64 operating systems, full support for all CPU features may vary depending on OS.[14] On 15 January 2016, Microsoft announced that Windows 10 would be the only supported Windows platform for Kaby Lake processors.[15] All future generation processors under Windows will follow this trend and will only be supported by the latest Windows platform at their time of release.[15]

TDP classification

Thermal design power or (TDP) is important it is the maximum heat generated by the chip. As heat increases with voltage, and voltage limits with maximum clock speed, TDP is directly proportional to computational power of a chip.
