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


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 try to speak S L O W L Y for you.

The cnet article quotes (you know QUOTATION MARKS?) perlmutter from his presentation. You know, he was on a stage. He was speaking. The audio/video presentation is still available along with the slide deck. He said "significantly improved IPC". C L E A R ?

How could this happen in a completely reworked microarchitecture? Oh, I dunno. L1 latency going from 4 to 3 cycles might help.

But I see. 10% is now not significant. At least you are on the record with your 2% prediction.
