![]() As a result, the successor to Skylake is not a “tick” release that reduces transistor size down to 10nm rather it is an optimization of the 14nm Skylake microarchitecture called Kaby Lake. ![]() This lifecycle is called “process-architecture-optimization.” This process reflects the need to leverage investments in ever smaller transistor process technology. The challenge of manufacturing chips at extreme densities has prompted Intel to adopt a three-step lifecycle. What Has Changed With Intel’s Processor Tick-Tock Release Schedule? Going back to 2010, there’s a similar dynamic between Westmere and Sandy Bridge and between Ivy Bridge and Haswell generations. So in the current generation there are no embedded-class CPUs within the 14nm Broadwell family (tick), while multiple embedded-class CPUs are offered within Skylake (tock). In its tick-tock scheme, Intel has focused embedded support on the tock side of the cadence. Intel embedded-class CPUs combine low power consumption for fanless operation with long support intervals, making them an optimal fit for Industrial PCs. This is something that’s rarely available with more commonly available consumer and commercial CPUs and chipsets. This matters because IPCs deployments often require assured support extending to five years or beyond. When the Broadwell CPU arrived in September 2014, it was a “tick” release squeezing transistor width down to 14nm and setting the stage for the “tock” release a year later when Skylake arrived. Just over a year later, the Haswell processor improved on the 22nm design by adding a wider core, new instructions and a host of other enhancements. For example: The Ivy Bridge processor in April 2012 introduced the 22 nanometer (nm) manufacturing process. Since 2007, Intel has released CPU architectures under its Tick-Tock model, where the tick is a CPU release that introduces a shrinking of the process technology used to build the chip, and the tock is an enhancement of the microarchitecture to improve performance and functionality. How do you adopt PCs with the right CPU for your embedded applications? These users must make informed decisions about the PCs they deploy, particularly for industrial PCs (IPCs) with stringent lifecycle requirements. But now, Intel’s tick-tock changing approach to processor releases poses a challenge to hardware users. From beefed up integrated graphics, to improved power consumption, CPUs with code names like Skylake, Kaby Lake, and Coffee Lake are raising the bar. And things don't stop there: Fisher told us that he is already working on a 22nm design, and elsewhere within Intel, teams are already figuring out what features might be added into the 16nm generation.Intel constantly rolls out new processors to slide into its Core i3/i5/i7 branding scheme. Intel plans to follow this strategy in the coming years, meaning that the 32nm generation also has two entries on the roadmap: 'Westmere' will be a conservatively shrunk version of Nehalem, while the progressive 'Sandy Bridge' is to add a good deal of new features. This luxurious position enabled the second team to concentrate much more on new features, such as the integration of multithreading, a memory controller and a video chip. Every obstacle that the first team encountered was a lesson for the second one, which then had an extra six to twelve months to solve it. For the 45nm generation, Penryn represents the conservative approach while Nehalem is the progressive one. This is why Intel chooses to explore two different approaches simultaneously, with an offset of about a year. On the other hand, doing things conservatively may lead to suboptimal use of the possibilities that the factories, which cost billions, have to offer. If problems are tackled in too radical a fashion, ideas may turn out to be impossible to implement. The first 45nm-chip was made in early 2006, less than a year before Penryn had to be finished.Ĭhanging characteristics of a manufacturing process, also known as 'design rules', present significant challenges to designers.
