[NEW STUFF] Intel LGA1155

[saaya]

I wanted to correct and clarify some of the conjecture here:

Sandy Bridge is a new µArch. It is not a tweak of Nehalem. Westmere was a tweak of Nehalem. Whether or not there are "major" changes in IPC from Nehalem remains to be seen. Most of you think that it's not likely to be a huge IPC gain and I tend to agree. Regardless, it is an Intel "tock" which brings a new µArch to an established process node: 32nm.

yes, its a tock, i know... new µarch, well thats almost a marketing term this days, isnt it?
if there is a lot of really new stuff in sandybridge intel sure has kept quiet about it... id love to be surprised in a good way... so im looking forward to some benchmarks in the following weeks

I'll try to speak S L O W L Y for you.

this is a F O R U M! people here communicate by W R I T I N G messages, you can speak as slowly and clearly as you want, i wont hear you

can we stop this? this is really childish man... please...
you need to reset your sarcasm, its way overloaded...

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.

yes, and at least years idf in taipei somebody said nehalem will heal cancer... cause its oh so fast at medical scientific calculations... like i said, they always make wild claims about their newest cpu... intel told system builders to not expect a major performance boost until haswell... they even had a slide about it in a semi public presentation to analysts... but i couldnt find it on anymore googling for it...

so you think dropping the L1 latency by 25% will result in a 10% performance boost?

Yes there is.
The architecture carries a new power regulation scheme.
Even if the socket is identical you will need a new chipset.

i dont think the chipset is that important... they could make the new cpus work with the old chipset easily i think... as a matter of fact the "new" chipsets arent really new, they have barely been modified from the current ones...

its all about the igp data and pwm protocoll as far as i know...
