[NEW STUFF] Intel LGA1155

[saaya]

Did I say that? No.
I merely suggest you might consider some of the already known changes (L1 latency, for one), in addition to the black box "completely reworked microarchitecture", along with Intel's exec VP stating "significantly improved IPC", before you make claims like: "SB will only improve IPC over Westmere by 2%, on average."

thats not what i said...

but i dont expect even that, i think sandybridge will be 2% faster than clarkdale on average...

so how much faster do you think sandybridge is going to be vs clarkdale at a clock per clock comparison?
i mean non avx code, common games and apps...
no video and audio en and decoding...

Just because Merom, Nehalem, and probably SB all stick with variants of the P6 *pipeline* doesn't mean there haven't been, and won't continue to be, significant IPC bumps along the way. There's more to the microarchitecture than the basic pipeline.

good point... they might have changed tons of stuff, it just didnt improve ipc a lot...

If you have read the article... Sigh nevermind. Here, I'll quote it right here. This is what they wrote:

lol what?
i did read it, and what did i say to make you think i havent?

Even though they were specifically talking about the extreme platform, I wouldn't be surprised if the rest of the line work the same way.

atom will stay vrm 11.1, and 1366 will move to vrm12 later iirc

Again, a BIOS flash is not going to give you a whole new regulation scheme. It requires hardware change.

Others in the thread have also mentioned power savings this new scheme enables. You also need new hardware for this, and it's probably not just at the bare chip level either. A BIOS flash isn't going to change that piece of PCB the chip rests on, either.

who are you talking to?
nobody said a bios flash would enable compatibility between the old and new platform?

Saaya is a troll, but I respect his opinion, even if it's mostly based on what he thinks in stead of the facts.

well im out of the loop for a while and things start to blur... why should i promise anything even if i THINK i know something for sure? so i get ripped on by some trolls that interpret something into my posts i never said? plus intel probably changed the one thing or the other, so im not 100% sure about any of this... i still think my comments are useful to get a rough idea of what to expect...

if thats how you define trolling, fair enough, yes, im a troll...
i define trolling as bear posts vs bull posts like in the stock markets... there are people that provide new infos and comments, and then there are people that disagree and try to discredit them...

I think all the performance speculations are useless at this stage. I'll bet you have no appropriate background to estimate a performance bust from an additional L1 load port

your right, i dont... so what is your estimation then?
and i dont want to hear any comment to later call you out on it, im just curious about it... i plan on getting an SB laptop, i cant wait to get my hands on one tbh... i just dont expect a big perf boost... in a laptop thats only secondary for me tho, hence my unbroken enthusiasm for this new platform

much bigger loop detector buffer

sweet, that should boost actual ipc vs theoretical ipc and be quite useful in a laptop...

(and other Sandy Bridge features which yet to be disclosed).

well how am i supposed to make any conclusions whatsoever from stuff intel is hiding even from some of their devs and partners? yes, there might be much more to sb that intel hasnt talked about that will result in notable ipc boosts... but since intel hasnt talked about it... at all... how are we supposed to know about it?

What Intel does disclosed is a performance speedup (1.42x - 2.57x) for AVX vs. SSE for various FP workloads. Also confirmed on actual Sandy Bridge silicon.

hmmm they said this particular code was very easy to port to avx... i wonder how easy it will be to actually port games and actual applications to avx... they also mention the speedup is sort of a best case scenario, still, its very impressive...
thx for the link, that article was very informative...
