[NEW STUFF] Intel LGA1155

[saaya]

? IDF Beijing? Perlmutter said it. As it said in the very article I linked, which you presumably read, as you quoted it.

Yeah, how could a new microarchitecture possibly improve IPC significantly? ><

i didnt read them, you quoted some info so i though that was the relevant info you were only linking there to provide a source...

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.

pff, they claimed the same for clarkdale over wolfdale, actually way more, they claimed ~50% performance boosts back then... and for nehalem they did the same vs yorkfield... those are all best case scenarios...

come on, its not gonna happen... whats the last time we have seen a 20% ipc boost over a previous gen cpu? the original a64 did it and conroe did it, and they only managed that because the previous gen they used was outdated and sucked and the new arch was doing above average. and in both cases it was a mayor effort from intel and amd to get those new archs out. sandybridge is a small stepstone for intel, its not a mayor new arch...

...

wow, so many temp probes... and it can display the current power consumption? neat!!!

65W tdp? must be because its ES...
no turbo boost? same i guess... or maybe early bios?
lowest multi is 16x? and it cant drop every second clock to get down to 800mhz?
why are there two 3.3v readings?
whats vccp2? uncore?

I'm confused.
Is sandy bridge just a tweak/core upgrade from nehalem? With minimal clock/clock performance increase?

Like i7 was to Yorkfield, no improvement in realtime single core apps.

My emulators demand something newer than the performance levels of 6 year old chips. We are WAAAY overdue for a real increase.

itll have better turbo modes, hopefully, so that will help with single threadded apps... somewhat...
the next real ipc increase will be haswell, 22nm... thatll be a mayor step... and bulldozer from amd, which will probably come out first, but itll be on 32nm so even if its good intel should catch up pretty fast with haswell on 22nm...

on intels latest public roadmaps it shows sandybridge as the next step on 32nm right?
after that comes ivybridge at 22nm and then haswell at 22nm.
haswell is a really revamped architecture... sandybridge and ivybridge are just that, bridges, to that revamped arch...
they are all tweaks of the original Yonah archicture that replaced netburst.

Shame though, my intel system is already at 4ghz. If turbo is the only major increase then I'm already doing it manually.


So, Haswell vs Bulldozer. I've heard the name bulldozer bantered about since I joined xs ....many years ago. I assumed it was an ancient architecture of the P3 era. Must have been the AMD forum clutching at straws over the failure of phenom 1.

bulldozer has been in the works since before conroe came out, possibly much longer than that... so thats... 2005 or earlier... but what they originally planned as bulldozer is very very different from what they are going to actually release...

i remember reading an interview at anandtech with some higher up at amd about half a year before conroe came out, that their arch was good enough and that for the next few years they would only bump the clocks up and that would be enough... i had a very bad feeling about amd back then lol...

I'm waiting for an upcoming AnandTech article named "The Sandy Bridge Preview: Intel Does It Again".

TDP and Turbo are correct for this one. Reason: Early Sample
Don't count on those Nuvoton NCT6771F sensor values, these are just generic outputs that need to be adjusted per a specific mobo (like all sensors on each mobo). Since this mobo is a pretty early sample, I'm not sure if I will be able to adjust them now.. Will see...

probably not worth it to adjust them then... the final boards will be different, even the intel ref boards that end up in retail will probably be different...

thanks!

Will post a similar screen of quad sandy bridge soon "Later today or day after" depending upon when i get the screens from a guy.

I'm waiting for an upcoming AnandTech article named "The Sandy Bridge Preview: Intel Does It Again".

mhhh anandtech is too mainstream... i dont think intel will ask them to publish a sandybridge preview anytime soon... especially since the target is mobile, and for that perf/watt is everything and i highly doubt they have that tweaked to a level yet that would look notably better than arrandale let alone culv... so that wouldnt be too smart for intel to show off... i wouldnt be surprised if jarred has a sample or will get one soon, or maybe johan/anand have a 6core or 8core sample now or soon... but i doubt they will be allowed to write about it...

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.

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, much bigger loop detector buffer, lower cache latencies, larger L3 bandwidth (and other Sandy Bridge features which yet to be disclosed). 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.
