How To Get All Components Based On A Schema And From A Particular Publication?

Are we going to get a fanless laptop as thin as 7.9mm?

  • Kirk Skaugen, general manager of Intel’s personal computing division,  announced the imminent arrival of the new designs during a speech at the  the IFA electronics show in Berlin. The new line, called Core M (also  known as Broadwell), essentially refers to Intel’s upcoming Broadwell Y  parts- the fifth generation of the Core-branded line which are  manufactured using a 14nm process. The 14nm process will let PC makers  build much thinner and lighter devices. The new move from Intel’s prior  22-nanometer chip, dubbed http://www.technepal.x10.mx/haswellto  14-nanameter chip not only makes device more power efficient but also  opens a new era of fanless laptops. The premium chip, which consumes a dramatically low 4.5 watts — less than even new power-efficient light bulbs — is geared for a  newer class of hybrid computing devices that can act either like tablets  or PCs. Even though intel chips power the majority of the world’s computers and  servers but it has not been able to foster in tablets and mobile device  market as they use ARM-based chips – including those from Qualcomm,  samsung and others. ARM-based chip consumes very less power. Removing a  fan is key for Intel as it pushes its chips in tablets and laptops that  can convert into tablets because chips based on http://en.wikipedia.org/wiki/ARM_architecture rival technology already allow for fanless designs.The Core M fulfills  the demand of low power consumption as well as fanless design as it  helps PC makers to create tablets and devices that can convert between  tablets and laptops, that Intel calls two-in-ones. And you will get in  those systems the Core performance you have come to expect of laptop as  well as slim body of tablet. “You have to ask yourself, ‘Why would I ever buy a tablet again?'” Skaugen said. Well, presumably because Apple iPads, and tablets powered by Google’s  Android operating system, have abundant software, while embracing  Microsoft’s touch-capable Windows 8.1 isn’t always a top priority for  programmers. But more affordable, capable hybrids could help Microsoft’s  vision become a reality. The Core M processor itself is the first to be built using Intel’s  14-nanometer manufacturing process, which has electronic elements  measuring just 14 billionths of a meter across. To deal with the physics  challenges of shrinking transistors to that scale, Intel moved to a  three-dimensional “tri-gate” design with transistor components poking up  out of the plane of the processor. Core M parts will be found in thin-and-light x86-powered tablets,  including Asus’ recently announced Transformer Book T300 Chi, towards  the end of 2014. Intel showed off a reference tablet as thin as 7.2mm  with a Core M part inside, which was completely fanless due to the CPU’s  low power consumption. Consider the Core M as the first of a “new product family,” said Kirk  Skaugen, senior vice president at Intel. He said it was designed to  deliver the promise of one of the world’s thinnest laptops and highest  performance tablets in a single two-in-one device. The processor package  is to allow OEMs to design sleek, fanless systems less than 9 mm thin.  Intel said there are already more than 20 Intel Core M processor-based  OEM products in the development pipeline. The first systems based on the  Intel Core M processor will be on shelves for the holiday selling  season. The Intel Core M processor can handle more than eight hours of video  play, a 20 percent (1.7 hours) longer battery life compared with the  previous-generation Intel Core processor and double the battery life of  the average four-year-old PC. To begin with, there are three members of the new Core M family: the up to 2.0 GHz Intel Core M-5Y10/5Y10a processors and the up to 2.6 GHz Intel Core M-5Y70 processor. With  a new family (Core M as opposed to Core i) comes a new, rather  nasty-looking numbering scheme. The “5″ roughly refers to the fact that  it’s similar to a Core i5 (i.e. dual-core with Hyper-Threading). “Y” is  the chip type (Broadwell-Y), and the number at the end is the chip’s  relative position. The “a” is an odd one, but it seems to refer to the  fact that the chip can be configured down to 4W TDP. Broadwell vs Haswell When new fifth generation Core M chips are compared with  fourth-generation Core chips, new chips are up to 50 percent faster at  computing and 40 percent faster at graphics. But Intel prefers to  compare the Core M’s performance to that of the chips in the many  4-year-old laptops still in use today. When compared, the new Core M  chip doubles computing power and improves graphics performance  sevenfold, Intel said. Intel compared it’s thin PC reference design —  about 7.2 millimeters thick which is thinner than an iPad Air to a 26  millimeter thick laptop from 2010, which vice president of Intel joked  could be used for weightlifting. Along with fanless devices, the Core M’s packaging is about 50 percent smaller and 30 percent thinner than http://www.technepal.x10.mx/haswell/,  which makes it better suited for smaller laptops. Moreover its 60  percent lower idle power level also helps to boost battery life. The key takeaway that Intel tried to hammer  home was that Broadwell-Y is a very efficient chip. It is the first  performance part from Intel that can be safely used in fanless designs  that are less than 9mm thick. In the closest comparison possible (the  Broadwell Core M-5Y70 vs. the Haswell Core i5-4302Y), the Broadwell-Y  part has up to 1.7 hours more battery life, and anywhere between 10-50%  higher performance depending on the workload. Most of these  improvements/reductions are down to Intel’s 14nm process, but  significant tweaks to the GPU and small (~5%) CPU IPC improvements  certainly help as well. Performance (CPU and GPU) On the CPU side, Intel claims Broadwell to be up to 5% faster than  Haswell, thanks to some minor tweaks to the TLBs (translation lookaside  buffers), better address prediction, and a larger scheduler. But real  life impact is likely to be unnoticeable. However, graphics performance is different. The new current  low-watt parts uses Intel HD Graphics 4200 solution which has a maximum  frequency of 850MHz that is similar to clock speed of top end chip (the  core i7-4770k) which clock up to 1.25 GHz. It seems that Broadwell’s  ultraportable GPU performance jump will simply put it on par with  Intel’s high-end desktop solution. That would still be a significant and  noteworthy increase. Intel said the first systems using Core M will hit store shelf for  the holiday season of 2014, but the bulk of new devices will be  available in the first half of 2015. An additional note about the Intel Core M is what Intel called a  “conflict-free” product, made without the minerals (tin, tantalum,  tungsten and/or gold) that directly or indirectly finance or benefit  armed groups in the Democratic Republic of the Congo (DRC) or adjoining  countries.

  • Answer:

    That's exciting news! To answer your question: probably. Explanation: I don't think this technology is going to allow us to get to laptops as thin as 7.9mm (which is slightly less than 1/3 of an inch).  While it's important to save space with the processor and removing fans, I think that we'll need to see some major breakthroughs, particularly in batteries, screens, and keyboards.  Currently, fitting a battery with reasonable power storage to run a laptop for 5-10 hours inside a laptop that small is probably unfeasible (although the processor's incredibly low power consumption might make this point of contention moot, I don't know). Additionally, fitting a monitor/screen in its own housing (like a laptop) requires adding more material to encase the screen, which inevitably adds thickness. Additionally, one of the largest differences between tablets (thin) and laptops (thicker) are that laptops have keyboards.  Keyboards, as they currently exist, will take up at least 1-2mm, if they're extremely thin, like the touch keyboard for Microsoft's Surface tablets (not laptops).  There will need to be an evolution in the paradigm of keyboards to significantly reduce their thickness. Short answer: Yes, but it will probably be in 5-1o years before it happens.
