If Intel's claims are to be believed, the new Atoms have 2x the performance of current Atoms, and they should be at least as efficient or even more so than current Atoms.
How many of us here [raises hand] have our "Atom" experience on first gen single core 1.6GHz Atoms in original netbooks?
Current Atoms hit up to 2.16GHz with twice the cache memory, faster bus speeds, faster system RAM, faster IGP and newer chipset.
As long as the price is good, I have no complaints with true quad core 22nm "Atoms" that have 2x better performance and possibly better battery life than current Atoms.
Time will tell...
The first gen atom didnt have integrated gpu as i recall?- and therefore had half-bad battery life, pineview had that integrated and sort of got acceptable battery life for the netbooks.
I once had a pineview atom 450 single core at 1.66 GHz. And yes it was just horrible, with a barely working gpu part. But it was horrible primarily because the single threaded performance was so bad.
AMD bobcat had 60% better single treaded performance at same MHz, and that makes the bobcat an usable platform. Its slow but its working and good enough for mom and your sister. Jaguar have aprox 20% better ipc than Bobcat so that acounts for aprox 80% compared to current Atom. 80% is a lot of difference, and then add its typically quad core.
The new Atoms is needed, and i think they will make a nice impression, but i think they will have a hard time figting the A57/A53 from ARM, and dont have the performance on the gpu part of jaguar. They are stucked in a difficult place. If MS win8 had been better, and more successfull Atom could be a very nice product for the x86 tablet market.
And i would like x86 compatability for my phone also, by i am quite confident i am a nice market here. The mobile platform is driven by play store, games, social network and so on.
But its nice we get some competition, and i am sure we will see som impressive battery numbers from Atom - unfortunately it seem efficiency in screen tech is what matters most in the future. And we are well past fast enough on the phones.
