Kaby Lake is an Intel codename for a processor microarchitecture they 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 "" 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 a Kaby Lake Refresh 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 has 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 from Microsoft for versions of Windows older than Windows 10, although an enthusiast-created modification was released that disabled the check and allowed Windows 8.1 and earlier to continue to work on the platform.
As with previous Intel processors (such as the 8088, Banias, Dothan, Conroe, Sandy Bridge, Ivy Bridge, and Skylake), Kaby Lake's development was led by Intel's Israeli team, based in Haifa. 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. Third-party benchmarks do not confirm these percentages as far as gaming is concerned.
