Kaby Lake is an Intel codename for a processor microarchitecture Intel announced on August 30, 2016. Like the preceding Skylake, Kaby Lake is produced using a 14 nanometer manufacturing process technology. Breaking with Intel's previous "tick–tock" manufacturing and design model, Kaby Lake represents the optimized step of the newer "process-architecture-optimization" model. Kaby Lake began shipping to manufacturers and OEMs in the second quarter of 2016, and mobile chips have started shipping while Kaby Lake (desktop) chips were officially launched in January 2017.
In August 2017, Intel announced Kaby Lake Refresh (Kaby Lake R) marketed as the 8th generation mobile CPUs, breaking the long cycle where architectures matched the corresponding generations of CPUs. Skylake was anticipated to be succeeded by the 10 nanometer Cannon Lake, but it was announced in July 2015 that Cannon Lake had been delayed until the second half of 2017. In the meantime, Intel released a fourth 14 nm generation on October 5, 2017, named Coffee Lake.
Kaby Lake is the first Intel platform to lack official driver support for versions of Windows older than Windows 10. Furthermore, Windows Update is disabled under Windows 8.1 and earlier, although an enthusiast-created modification was released that disabled the check and allowed it to continue to work on the platform.
