Re: No doubt to be followed in 2014...
I'm sorry but you are wrong and ARM is frankly a fad. The users will soon grow tired of it when it hits the powerwall (Nvidia is already up to 5 cores, Samsung up to 6) and can't squeeze any more performance out of the chips, it just doesn't scale up very well and the best chips being made can't even beat a Cedar Mill P4 in IPC.
No what has happened to Intel and AMD is something we PC retailers have been predicting for quite awhile now which is thus: PCs passed "good enough" and shot straight into "insanely overpowered" several releases back. Look at what I was selling on the LOW end FIVE years ago, Phenom I X4 with 4GB of RAM and a 500GB HDD with a Radeon 4200 IGP. How many of your average users are gonna be able to max out that system? Not many. Heck I love to game and built myself a new system every year and a half, now I'm using a 3+ year old box, heck I didn't even really need to upgrade the Deneb quad to a Thuban Hexacore but when I found Hexacores for $100 I couldn't pass the deal up.
The simple fact is your average user will be WELL served by a first gen Phenom X2 or better or on the Intel side a Core Duo first gen or better because the software just hasn't been able to keep up with the huge leap in processing power since the MHz war became the core war. Take my dad for example whom I use as my perfect "average user" metric because everything he does with his PCs is mainstream. He watches videos and surfs, he chats and checks his webmail, runs his quickbooks and burns discs, as average a user as you could possibly get. When the Phenom IIs went on sale cheap I thought "Ya know, its been a few years since I built him that Phenom I quad home and office systems, maybe I should see if he needs a new unit" so I set up performance logging and came back in a couple of weeks...know what I found? 45%, that was the MAX he had been able to use after 2 weeks of daily use, 45% CPU. Most of the time 2 or more cores were twiddling their thumbs waiting on useful work to do. I found the same is true when it comes to my netbook, I figured that AMD E350 netbook would last me MAYBE 2 years and then I'd get another, instead what do I find? For the things I do when out on service call the netbook works perfectly, so why buy another?
And THAT is why sales are down. I predict the SAME will happen to ARM in less than 2 years, you already have companies piling on the cores trying to get more IPC and yet you have ARM Holdings talking about "dark silicon" because if you turn everything on with their new ARM64 chips you'll have battery life measured in minutes. Other than Apple who has dedicated fans who look at using last year's iPad as practically a sin most companies will end up in a race to the bottom (just like X86) as fewer and fewer feel a need to buy the latest tablet because that Tegra multicore does everything they want it to do. The simple fact is we haven't had a "killer app" since the end of the MHz wars that can actually slam what we have, a few tiny niches like CAD need every cycle they can get but most users? Wouldn't feel any difference between that first gen Phenom X4 or C2Q and a system with the latest and greatest so why buy a new one?
