let me read it now...
ok, the cnet article doesnt mention anything new, you had quoted the important parts, but they dont mention a significant ipc boost... at all...
the article mentions that sandybridge is intels most important design for the future... well yeah, like clarkdale was a few months ago
that doesnt mean itll be notably faster...

they demoed a laptop running "some" medical imaging program... they dont mention the performance, nor the name of the app, nor did they compare it to a clarkdale laptop to show a performance boost... so if you ask me, this sounds just like intel saying
a.) we got sandybridge up and running, see!
b.) its performing well

they dont mention improved performance vs clarkdale at all in that article...

lol, page 15 and following they make it look as if the different atom processors were entirely different chips
they are talking to engineers there at idf... do they really think they fall for this nonsense?

no mention of performance (besides avx)


improved ipc...


i see... so they did mention improved ipc...
they didnt mention improved performance though, and they dont mention "signficiantly improved ipc" as you said :P

improved ipc can mean many things... the revamped cache structure alone probably improves the ipc already... barely... but it does... so that would already count as an ipc improvement.
we will see, but i will be VERY surprised if there is a notable performance boost of sandbridge over clarkdale, besides gpu and avx, those might get a boost...

i should define what i mean by that though... even if sandybridge is 5% or even 10% faster than clarkdale at the same clockspeed, thats not a notable performance boost imo... thats not a reason to upgrade your laptop or pc, its like a mhz boost from 2000mhz to 2200mhz... thats nothing, you wont notice it...

but i dont expect even that, i think sandybridge will be 2% faster than clarkdale on average... the important points will be lower power consumption, more features (avx,better turbo,tweaked igp) and price...
I'll go even further and say IF intel manages an average of ~15% increase in IPC over same clocked(same turbo ability) clarkdale,than it's a success as far as the "significant IPC increase" story goes. Intel claimed,back in February,a 20% increase on unnamed workloads(may very well be a mix of computational and 2D/3D GPU heavy application),over same clocked arrandale/clarkdale chips.
