content: Back in the day it was all about the clock speed, and overclocking. I went through all that.Then it turned to multi-core CPUs. I currently have a 6-core Athlon, and haven't upgraded in about 3-4 years.I used to keep up with the technology, but since it got so damn capable I just lost interest. So from you guys (and gals) in the know, where is the technology headed?More and more cores - or where?

content: Quote from: c4757p on May 12, 2013, 12:20:57 amI agree. I haven't wished for my PC to go faster because there is nothing for it to go faster to do.I really thought by now (2013) I'd be simply talking to my PC and it being able to carry out my commands as I stated them - no keyboard. I don't think that's really requires A.I. - doesn't it just require a language parser and a fast CPU? Either I'm wrong (we are to dumb to program this yet) or we are just not going in the direction I (and a lot of others) thought we wold be going by this time.

Act as a GPS? Provide a moving map display with voice directions? Be a fully featured web browser? With a high res color display? Play games like Angry Birds and Cut the Rope? Be a speaker phone? Store and play 1000 hours of music at hi-fi quality? Store and play video and movies?

content: Quote from: c4757p on May 12, 2013, 12:20:57 amSemiconductor manufacturing is pushing up against the limits, but even now we have no idea when (if ever) it will stop. Most likely the continuation of computers getting faster would be around new and redesigned architectures and eventually, some new materials.As for demand for computing power, we'll never meet it. Every time someone comes out with a faster computer, many find a use for it. Many things once considered impractical to do at home (like real time video processing) are now easily done on common PCs.Considering that networking is improving at a much slower pace than computing, I think a great application of more computing power would be to make the most of network bandwidth. With almost all mobile ISPs having data caps, fight back by using computing power to aggressively compress stuff as well as prefetch using alternate paths when possible. Maybe even create a whole new P2P network (let's just call it "YepNet") that is free to use as long as you have the hardware.

Cellular Internet access is just an extension of the fact that many had mobile service, it was bound to happen eventually. GPS? Yep. It wasn't integrated, but Wi-Fi wasn't integrated into laptops years ago and we didn't stop calling them laptops when it was added. Everything else is just a realization of "faster".

Only the most dedicated idiot would have wanted to buy that thing and attach it to their PDA.A Pilot was an executive toy, used by a few. Today's iPhones and Androids are used by every teenager everywhere. The difference is the convenience of small size, long battery life, and broad appeal.It is not so much technical features that make a difference, but convenience and accessibility. Just the same as personal computers took off when they were no longer the size of a mainframe.

All I'm saying is that a smartphone and a Palm Pilot are both PDAs in the same way that the IBM PC-XT and my laptop are both personal computers. Yes, they've changed alot. But they're still fundamentally the same thing and go by the same name. At no moment along the evolution of the PC did we get something shoved down our throats by a marketing weenie as being something completely NEW!! because it never was. Then Apple realized that they could monetize the cell phone market by slapping "teenager" features into a PDA, polishing it until it blinds you, and never uttering the term PDA in the marketing materials.

content: Quote from: c4757p on May 12, 2013, 01:24:49 amBut it's not about marketing, or "teenager" features, it's about utility, meaning convenience. I'm not a teenager (far from it), and consequently I have owned and used a Psion 3a and a Psion 5. Both failed because they didn't do enough. They weren't phones, and they didn't have wireless networking. Sure, they could plug into phones, but who wants to plug their PDA into a phone and do a modem dial up?The advance of humanity is not about technical features, but about the convenient delivery of technology at the point of use.Until you make your technology convenient to use, it is not useful. This is a lesson engineers everywhere must always remember.I'm not "blinded" by Apple marketing, I simply like my iPhone because it does helpful things where and when I need, with a minimum of friction or inconvenience. The iPhone succeeded not because of a powerful marketing machine, but because design engineers realized that market appeal is all about packaging attractive features and delivering them in an easy to use format. The iPhone didn't need selling, it sold itself.

Apologies if it sounds like I was accusing you of being "blinded by marketing", that's not what I meant to say at all.I'm not really arguing here, just clarifying. I mostly agree with you, except on the rather unimportant technicality of terms. A PDA never was a phone, but I really do still think a smartphone is just a more advanced PDA. It became easier to use in the same way that PCs did, but PCs are still PCs. Still, it really doesn't matter a rat's ass if a smartphone is a PDA or not, so I'll just stop arguing...

I quite agree that an iPhone is a PDA.What I'm really trying to say is that technology takes off when it crosses some threshold where a majority of people find it appealing and easy to use.Understanding this, and working on how to make whatever technology you are currently involved with convenient and easy to use, is lesson #1 for any engineer.

content: Quote from: Rasz on May 12, 2013, 01:50:28 amThe trade off, of course, is much less flexibility. The scientists behind Folding@Home have created a system (points) to normalize CPU and GPU performance in scientific applications. My 3930k gets more PPD/$ (and PPD/W) than my GTX560Ti, even though the GTX560Ti was (at the time) near the peak of the performance/$ curve and the 3930k is way "over the hill".Now if you're doing 3D rendering or Bitcoins, the GPU would (obviously) win. But for Bitcoins, FPGAs (and later on, ASICs) will beat both CPUs and GPUs. It all depends on your application. (Guess why Tiffany Yep has a 2700k, two GTX580s, *and* some Xilinx FPGAs in her DSP experimental setup...)

I still use my Treo when I am out long (I like the complete phone book and Blackjack on it), but if I am out less than a single day, I grab my dumb phone.

content: Quote from: IanB on May 12, 2013, 01:19:33 amI read in an article that the biggest iPhone/iPad/iSomething market is the 6-11 years old. I was somewhat surprised when I read that. Then I thought about events at my daughter's school that I've attended. The iSomething as baby sitter was omnipresent. Moms and Dads were there watching their kid play in the band. Some brought along the younger kids. Of those, at least one out of 5 were poking away on their iSomething playing some games. That works, they were not making any noise disrupting the musical performance.I do wonder when these kids grow up, will they learn much? They were so glued to their games. I hope this only happens on special occasions and they would be as glued to their work on normal days. But, I think that is unlikely.

How many 1K ram boards can you plug in (and they were full size S100 boards).A colleague of my had a rack (before today's standard rack mount size), it was about 2 feet by 1 feed deep. The lower 3 feet was devoted to power supply. He had an 8080 with almost 48K of ram.I had a 4K board and an 8K board and that was all my psu can take. I think the 4K board was just under $500, and by the time they introduced 8K, it was merely $600 and change.

content: Eventually your smartphone will be able to easily stream HD video to a nearby TV/Monitor over some form of gigabit wireless.(Some phones can kinda do it already using upnp servers but full HD quality is a bit much at the moment)ie, You could check your email on the phone itself, Or you could sit down next to a bluetooth kbd/mouse and wifi monitor, swipe your phone over some RFID tag (to trigger autoconnect) and then work on more involved things like reading datasheets, routing circuit boards etc.. in a desktop style environment.For general desktop email/web/document tasks phones have plenty of cpu power (or they will very soon)However it will take quite a while before the latest computer games drop PC support for phones/pda.It will probably happen though. For gaming you will pair your Oculus rift version 6 to your phoneMakes me wonder if people might end up walking around wearing some for of VR googles most of the time.A high megapixel mounted camera would allow them to see with better than normal vision and would allow for google glass style OSD info, image zoom and all sorts of cool features.It would have to be looked-on as "cool" to wear one though, before it would become popular, and that maybe a bit unrealistic.

content: Modern phones have more than enough power to run Descent 2, yet I still play Descent 2 (more accurately, the modern version D2X-XL) on a high end PC. The game physics haven't changed much since the original, but the graphics effects have evolved to the point where even modern hardware can be pushed to the limits. (Not bad for a game that originally came out 17 years ago!)So while very interesting games can definitely run on a phone, there's always the desire for more. Pretty soon, they'll be asking for 3D games on a 4k (or 8k!) screen (or several!) at 240 FPS, with a set of high speed, high resolution IR cameras as the controller.

A move to crystalin optical CPU's driven by a wide spectrum of light, the light operating within the crystal can be routed in 3 axis. Very low power and very low energy absorbtion.

content: For the past decade the CPU market has been fragmenting: raw processing power, medium power, low power etc., and now the PC itself is too. At onset the PC was the swiss army knife for data, now there is the laptop, smartphone or tablet to consider when the oft used application is best suited to that form factor, and portability.The bottom line to all of us, is that CPU prices has not dropped as it used to be in the heydey of PCs. My quad core q8200 CPU has actually appreciated to $160+ since I bought it, and while discontinued by Intel is still sold;my PC has actually appreciated in value,I paid $3400 for it, it was such a steal I bought 2 back in20072010; an equivalent PC today cost >$600each using a similarly capable CPU.I suggest if you are a power user: CAD/CAM, simulation, graphics, multimedia editing particularly video, you either own today or should get a capable desktop now as prices will only continue to rise as the tablet and laptop market continue to erode the PC market share, so few deals will be had from hereon in.

Thanks to your challenge I've checked the actual prices and made corrections to my prior post.A point I make is bang for buck in modern PCs is not as marked so buying a quality desktop today will hold performance longer; the 4 year old Q8200 quad core desktop I paid $400 for can hold its own against a newer dual core G870 for $370, pricewise the differences is nearly nil as sales taxes on $370 would making them roughly on par.http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7794133Readers can decide the value of these synthetic tests over an application specific one.http://cpuboss.com/cpus/Intel-Pentium-G870-vs-Intel-Core2-Quad-Q8200Yes, I wouldn't buy a Q8200 today given the 870's capabilities.Quote from: Rasz on May 14, 2013, 02:36:58 pm

content: Yes, I was going to reference Passmark results too, but in general I read these synthetic tests are ~ par. I feel benchmarks help categorizes CPU so one can then proceed to applications specific tests to find out who truly is better, once a full PC system is assembled using those CPUs; you'll find that other substems: e.g. mobos and memory, play a part on overall performance for the final most vital test: a user's experience.Which brings us to the concept of obsolescence. Since the user experience is primary, a simple rule was established by Miller in 1968, and subsequently reinforced by other researchers as a way to optimize system response time. It guides all phases of design, both hardware and software. It won't matter whether the technology is fresh or decades old, from desktops through the network latency, speed is all that matters, as well as reliability, and total operational costs.http://www.nngroup.com/articles/response-times-3-important-limits/If the task you need completed: wordprocessing, spreadsheet crunching, video editing etc., whether local or virtual, can be completed in 1 second or less, your machine and network is optimal. If not, one can consider upgrading. Currently, my only issue with local processing using my Q8200 is high end video editing which fails the 1 second rule. The CPUs may also fail certain gaming apps, but since I don't game, it this context is doesn't apply to my system.Quote from: amyk on May 14, 2013, 09:25:41 pm
