Post-post PC: Materials and Technologies That Could Revive Enthusiast Computing

Dputiger writes "Given the recent emphasis on mobile computing and the difficulty of scaling large cores, it's easy to think that enthusiast computing is dead. Easy — but not necessarily true. There are multiple ways to attack the problem of continued scaling, including new semiconductor materials, specialized co-processor units that implement software applications in silicon, and enhanced cooling techniques to reduce on-die hot spots."

      GaAs semiconductors have been around for years. The issue is it sucks at oxide growth and therefore makes it expensive to fab.

      You can get around this by adding aluminum to GaAs, creating a hetrojunction transistor. Other materials like Indium can be used as well.

      The beauty of these materials is you can get different bandgaps making it possible to create a true multijunction solar cell bumping up the conversion efficiency to around 40% which is almost unheard of in normal Silicon solar cells. The devices also have the advantage of running at multi GHz speeds with little issue.

      The PC is the correct form factor for getting work done by humans. Mobile devices are not.

      I'd say, instead, that the desktop and laptop PC are the correct form factors for getting done the sort of work that you do when seated for a long time. There are probably people whose work is sometimes done while on the move and for which a desktop PC is obviously not going to work and for whom a laptop PC might not work very well; consider, for example, somebody managing a construction project who might need to look things up, enter data, do some calculations, etc. while on site. I suspect that a mobile phone would be the wrong form factor for them, but a tablet might be the right form factor.

      I'll actually give you a primary source, real life example.

      I'm a paramedic, every single patient for whom I have responsibility of care for, I have to generate documentation for. Up until about 2008, that meant actual paperwork, about then, the industry as a whole being phasing in electronic medical records. To the business office, they're great, because billing the patients, and keeping the records is much easier, and for me, the end user of the system, it's great because, especially when you're using a touch screen and a properly designed program, the computer is much faster and easier to use than a pen (especially for me, my handwriting sucks balls.)

      Up until this point, and I imagine for a while into the future, the solution of choice has been to use the Panasonic toughbooks that will convert to a tablet form factor (CF-18s,-19 etc). The touchscreen is necessary, because we actually use it to collect signatures (quite aside from the fact that stabbing at options on the screen can easily cover 99.5% of the use cases), the portability was of course necessary, because I start my paperwork in the pt's house and finish in the ER, the keyboard was necessary because I have to type up a narrative for each pt, and the ruggedness was necessary because we beat the hell out of our machines. e problem is, even the older machines are WAY more powerful than we need, not to mention being heavy as hell (remember, I have to hand these to 96 yo pts to get a signature.)

      These EMR suites are starting to be developed for tablets, both iOS and android, and the market is starting to come up with workable ruggedized tablets. nce we get over the industrial inertia we have (which is surprisingly significant, given how agile we're supposed to be), we're going to move to tablets with some sort of external keyboard (at a guess, at odds with the ruggedized tablet, the preference will be for keyboards cheap enough to be effectively disposable), and it will be the right solution for us.

      No, my biller and office manager will still be using a full blown PC, but in the field, not so much.

      Yes and no. Tablets, phones and everything in between are replacing an aspect of computing, and that's strict consumption. Grandma doesn't need a PC to read email or look at grandkids photo's, she can use a tablet and have a much better user experience and gains the benefits of portability and reduced power use. People will use them to read books, watch movies or browse the internet. In general they won't be using them to create anything.

      Almost everyone I know has a tablet, me and my wife each have one. We use them for light content consumption and casual entertainment. This is the use that the vast majority of people using tablets are using them for. That's a niche that isn't going away. Tablets are here to stay, just like PC's will continue to be used in business and computing that involves real work or creation of anything.

      What's changed in this area and will likely be detrimental to the whole business is that PC's are now good enough. The CPU's are far more powerful than most people need except for special areas like engineering. But on the flipside Tablets aren't going to be yearly, bi-yearly or even tri-yearly purchases, people won't generally be buying to upgrade. They, for the most part, provide everything that's needed right now. The only way they will be able to drive sales is by making them lighter or have longer battery life. Otherwise sales will be related to breakage (or the hardware wearing out) and population expansion which will mean significantly less sales than the initial sales where everyone bought one. I personally expect tablet sales to drop off precipitously over the next 5 years.

      So year, there isn't a post-pc world, but tablets aren't going anywhere either and the tablet form factor satisfies a LOT of general use among the general population. Combined with the fact that CPU's are generally good enough means PC's sales are going to remain stagnant for the foreseeable future. Tablet sales will also likely stagnate or decline significantly once the market has saturated. Neither will be seeing the sales the PC's have enjoyed for the last 30 years and it's going to be severely detrimental to the business as a whole.

  4. Rumors of Si Death Have Been Greatly Exaggeratted by BarneyGuarder · · Score: 3, Interesting

    The new semiconductor technology angle in the article seem highly fishy to me. Apart from the fact that the statement felt like it may have said "In 10 years we will all be living in colonies on the moon", III-V materials have been losing market share to silicon for decades.

    The article mentions that great electron mobility of the III-V materials, which is true, but forgets to mention that they had poor hole mobility. Now I am not a process expert, so maybe there are new techniques to address this. However, over the past 20 years or so this meant that you couldn't make very good CMOS logic and had to use NMOS only architectures. This and the poor scaling has kept the III-Vs away from large scale integrated logic chips.

    The III-V devices were used in RF circuits, but they were replaced by Si-Ge and now many RF circuits use regular silicon processes. The III-Vs are still useful for optics.

    The truth is that silicon has many problems that may prevent the industry from continuing to scale circuits to smaller geometries and the available workarounds are generally painful. But, the other options are worse.

    Maybe in 10 years we will all be using cell phones that use carbon nanotubes... in our colonies on the moon.
