"There's a lot of nonsense here. The ARM instruction set IS more efficient, for people who understand technology, instead of repeat what they hear from their Intel reps.
There's no question about this. A quick class in microprocessor design will make this clear enough The question is only, does it make enough of a difference. It's not big enough to make other advantages irrelevant, and is certainly less of a disadvantage than having a superior manufacturing technology is, in this case. But, it's still a disadvantage, just not a salient one in today's world. As other things equalize, if they do, it will be more of an issue. Right now, it's a quite minor consideration.
The power/efficiency is pretty good, but the IPC is poor. It struggles to compete with Kabini in CPU, winning some, losing others, despite being able to turbo boost from the base 1.5 GHz both run at, all the way up to 2.4 GHz(the tested Kabini was stuck at 1.5 Ghz). IPC is markedly inferior. Forget the GPU, it gets annihilated completely. It's a complete blowout there.
Not that this is necessarily bad. Intel can't do graphics. They don't know how. Not smart enough. They try, they fail, they embarrass themselves. Better to spend their watts on CPUs, which they do know how to make quite well.
Bay Trail isn't a success, really. It's not bad either. It's disappointing, but only in a minor way. Power use is good, but not crazy good like Intel was boasting, IPC is fairly horrible, especially when compared to Kabini, and the GPU is miserable. But, taken together, as a sum of all parts, it's got nice CPU performance for the watts, and can still be very attractive in devices that don't need a strong GPU.
The problem is the same as Haswell - Intel built it up too much. I was expecting a much stronger GPU. It's surprising how poor it is, as a newly released product and with all the talk from Intel, but it's still functional in many scenarios...
Kabini is in Haswell's power consumption class not Bay Trail and so Bay Trail will last 50-100% longer on the same battery yet Bay Trail is in same cpu performance class. I am not convinced anyone buys tablets as a gaming device so as long as the gpu can power the chosen screen resolution that's the job done but just in case Haswell-Y has both better cpu and gpu than Kabini in the same power class. When Airmont arrives Intel will close this gpu gap and Kabini will have nowhere to go but extinction. Semi is right, Silvermont is the new T-34 of the mobile world and it will knock out all the inefficient ARM/AMD panzers it faces.
"It's clearly not a game changer, outside of the fact the previous Atom sucked and was completely garbage. But, in the sense that it's going to compel companies to use it because it's so much better, it's just not going to happen. It's competitive, for sure, but it's not going to change Intel's fortune.
I'd dump this stock after this release. Any chance they had of getting out of the doldrums is gone. Bay Trail is good enough to gain some share, but not good enough to make a real dent in the market where Intel would get a big enough share to change their earnings appreciably.
New products, especially highly touted ones, built from scratch, costing massive amounts of money, have to do better on their release. This isn't a modified Atom, it's completely new. It's not a Jaguar, which is an iteration on the Bobcat. It's new from the ground up. And it's just not good enough for what it is - losing badly in GPU performance on its release. Also keep in mind, it's only 32-bit now. Can only support 4 GB. It's not capable of working with Android, which matters more in tablets than Windows.
It's hard to believe a company with Intel's resources could fail to get these things done on time.
Intel has become a disappointing company. First Haswell, then Bay Trail. Not bad products by any stretch, but also with too many flaws to be fully satisfying either.
Bay Trail will get old fast in this industry. I'm more and more convinced AMD is having problems with Jaguar, as the number of design wins shows a lack of product, not to mention supporting products like motherboards. That's bad for Intel, because Bay Trail's weak GPU performance will limit higher end tablet sales, and without AMD to hold customers in with Jaguar, it will limit the Windows market, possibly permanently, as Android and iOS could become intractable standards. Windows 8.1 makes x86 more important, so its success is beneficial to Intel, particularly long term."
I cannot comment on this as I have no expertise, but the guy seems to be obsessed with the "fine driving machine" qualities of stylish European cars that don't have much power, don't last, and you dare not take them on a road trip or park them out in the sun. My Dad always said that we won WWII for Europe because Jeeps lasted and they worked, even if they weren't pretty. This guy seems to need a pretty machine language and well-styled IPC...but in any case, Bay Trail seems to be blowing the hinges off the competition in power efficiency, so Intel got something right and battery life is important to me. .
