The first step was to launch a new engraving on a mastered architecture, the next year a new architecture was introduced to take advantage of this improved thinness and, finally, the third year was used to optimize all this. Intel was talking about a new strategy in three steps, over three years: process / architecture / optimization. In reality, a tick could also be accompanied by some new features, but this was not the main element.Ī strategy that Intel maintained for a decade, but then abandoned when it seemed unable to keep up. In the first year (tock), Intel launched a new architecture based on a previously tested chip, while the following year, the tick was an opportunity to introduce a new chip while keeping the previous architecture. It was an alternation between two technical evolutions. The scheme was then called tick-tock and the idea was quite simple. Future processes require more complex manufacturing and more exotic technology-IBM recently demoed a 7nm chip, though the commercial viability of this manufacturing process is less than clear-so these delays may become a common feature of the future.More ambitious and enthusiastic than ever, Intel is talking about a return to shorter cycles for its future processors.įrom 2006 to 2016, Intel had implemented a two-year evolution cycle for its processors. Krzanich indicated that this may not be the end of tick tock forever and that a more regular two year-per-process timeframe was still the long-term desire, but Intel's difficulties and changed plans show the continuing challenges with keeping pace with Moore's Law: the rule of thumb coined by Intel's Gordon Moore that transistor density will double every 18 to 24 months. Little concrete is known about Kaby Lake, but it's likely to be available in a range of lines from a 4.5W laptop part up to 80W dual-socket server and workstation parts. News of this processor appeared to leak last month along with its full name: Kaby Lake. Like Skylake, this processor will continue to use the 14nm process. Cannonlake is being pushed back, from 2016 to the second half of 2017, and in the interim, a third "lake" generation processor will be released in 2016. Transitioning to 10nm isn't expected to be any better, so Intel is extending the timelines. Kaby Lake breaks from the 'tick-tock' schedule that Intel has followed for most of the last decade that schedule has been replaced by something Intel calls ' Process, Architecture. The migration to 14nm was more challenging than anticipated, and there were issues too with the previous migration to 22nm. In a call to shareholders after announcing its financial results today, Intel CEO Brian Krzanich confirmed that this plan has been derailed. This was to be the next tick the processor architecture would be minimally changed, but the manufacturing process would switch to 10nm. The original plan was for Skylake to be succeeded by Cannonlake. Later this year Intel will release the first Skylake processors these will continue to be built on 14nm, but will contain a range of architectural improvements, and as such are a "tock." Since 2007, Intel has been operating on a staggered release schedule that alternates manufacturing process shrinks-"ticks"-with major microarchitectural improvements-"tocks." For example, the current generation Broadwell processors are a "tick," being the first processors built on the 14nm process. Intel has confirmed today that it will build a third generation of processors on its 14nm process, and that the switch to 10nm manufacturing has been delayed until the second half of 2017, showing the challenges that Moore's Law is under and bringing an end to the company's "tick-tock" strategy.
