Sorry, you'll have to forgive me for being a bit sleepy when I wrote this. I've corrected the error and been sufficiently flogged for my inability to get the architecture names right. :-)
Thanks Jarred! thats what i love about this site, feedback and not too arrogant not to admit mistakes and change. good stuff.
LONATHE; you miss the point, clockspeed has got nothing to do with architecture which is what he was comparing.
Also the dmips numbers are not accurate numbers as they are only in cache, when it misses cache it comes down to other parts of the architecture.
By all accounts performance should be very competitive between Krait/A15, with the Krait able to be smaller and more power efficient.
Also the clock speed advantage you suggest doesn't make sense anyway as Qualcomm will have quad core Kraits out this year at 2ghz and 2.5ghx early 2013...cortex a15's will only come in duel core (with a couple of low power companion cores) on any road map.
Krait will be as/nearly as fast, more power effiecent, smaller, come in quadcore config and has time to market advantage.
Yeah, at last, something to excite me in this form factor. An x86 SoC. 1st thing to come to mind, DUAL BOOT. Yeah, for most people, they will just look over it, but I have been using the "humble" Atom 330 1.6 GHz, with 4GiB of mem, it is more than adequate.
Can't wait to see if it will be done by Lenovo, or some others that will 'hack' the system to make it dual boot. Full Win 7/ 8 and ICS on the one system. I guess when it goes to Win they battery will suffer alot.

I'm sorry, but the Krait architecture is more similar to the Cortex-A15, not the A9.lonathe - Tuesday, January 10, 2012 - link
just to add:the commonly circulated figures are:
Cortex-A9：2.5MIPS/MHz
Krait：3.3MIPS/MHz
Cortex-A15：3.5MIPS/MHz
However considering that snapdragon doesn't seem to have target clocks of >2GHz until 2013, it looks like the cortex guys win again.

The advantage Krait has over the A15 is the time it'll be out.french toast - Sunday, January 15, 2012 - link

You are contradicting your own site..the Krait is comparable to cortex a-15s not A9s.Thats what Anand said anyway.

Still, exciting products.
