Kaby Lake is the codename used by Intel for a processor microarchitecture which was announced on August 30, 2016.[4] Like the preceding Skylake, Kaby Lake is produced using a 14 nanometer manufacturing process technology.[5] Breaking with Intel's previous "tick-tock" manufacturing and design model, Kaby Lake represents the optimized step of the newer "process-architecture-optimization" model.[6] Kaby Lake began shipping to manufacturers and OEMs in the second quarter of 2016,[7][8] and mobile chips have started shipping while Kaby Lake (desktop) chips were officially launched in January 2017.

Skylake was anticipated to be succeeded by the 10 nanometer Cannonlake, but it was announced in July 2015 that Cannonlake has been delayed until the second half of 2017.[9][10] In the meantime Intel plans to release a fourth 14 nm generation in August 2017 named Coffee Lake. Kaby Lake is the first Intel platform to lack official driver support from Microsoft for versions of Windows older than Windows 10.[11]

Development history

As with previous Intel processors (such as the 8088, Banias, Dothan, Conroe, Sandy Bridge, Ivy Bridge, Skylake), Kaby Lake's development was led by Intel's Israeli team, based in Haifa.[12] Intel Israel Development Centers manager Ran Senderovitz said: "When we started out on the project, we were only thinking about basic improvements from the previous generation. But we began looking at things differently with a lot of innovation and determination and we achieved major improvements." He added that the performance of the seventh generation chips was improved by 12% for applications and 19% for Internet use compared with the sixth generation chips.[13] Third-party benchmarks do not confirm these percentages as far as gaming is concerned.[14]

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,[15] resulting in identical IPC (Instructions Per Clock).[4]

Kaby Lake features a new graphics architecture to improve performance in 3D graphics and 4K video playback.[4][16] It will add native HDCP 2.2 support,[17] along with fixed function decode of H.264, HEVC Main and Main10/10-bit, and VP9 10-bit and 8-bit video.[15][18][19][20] 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. OpenGL 4.5 & OpenCL 2.1 is now supported.[21]

Kaby Lake is the first Core architecture to support hyper-threading for the Pentium-branded desktop CPU SKU. Kaby Lake also features the first overclocking-enabled i3-branded CPU.

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.[24] Microsoft only officially supports Kaby Lake on computers running Windows 10 per support policies, and Windows Update blocks updates from being installed on Kaby Lake systems running versions older than Windows 10. In support of this position, Intel only provides chipset drivers for Windows 10.[25][26][11]

Known issues

Kaby Lake has a critical flaw where some short loops may cause unpredictable system behavior. The issue can be fixed if the motherboard manufacturer releases a BIOS update with the fix.[27]

TDP classification

Thermal design power or (TDP) is the designed maximum heat generated by the chip. On a single microarchitecture, as the heat produced increases with voltage and frequency, this thermal design limit can also limit the maximum frequency of the processor.[28] However, CPU testing and binning allows for products with lower voltage/power at a particular frequency, or higher frequency within the same power limit.[29][30]
