So, ya not that impressed but the volts are nice, i would like a i7 based on 32nm tough.

Your chip is a pretty special one and pretty rare among 45nm based ones. The 32nm cpus will go a lot easier above 4Ghz and with less voltage. Its called progress.

4g with 0.8V

**Monstru** · 10-22-2009, 04:27 AM

Pi 2M has nothing to do with 30 minutes prime, but that is indeed a very good E8500.

i5 750 at stock is mush stronger than i3 540 at stock....

Not that I fully don't trust their graphs but please wait retail boards/bios and chips

Also look at GTA4, how can 750 beat 860 by almost 20%? Is it just because they turned HT on? Why did they not test 860 without HT?

**Jamesrt2004** · 10-22-2009, 06:54 AM

waiting on this cpu.. will it beat Q6600 in threaded apps is my only Q as it being 2core 4 threads??

and "close to" 4gz at only 0.84v is incredible.. amazing for htpc's with a corsair H50 or something

**RPGWiZaRD** · 10-22-2009, 07:25 AM

I may even switch my bad sample i7-860 for a 32nm i5 if average max overclock (on air) is high enough, say 4.6~4.70GHz at ~1.4v. I don't care that much if I'd lose 2 cores cuz like 95% I use doesn't offer any improvement over a dual core today still and then this still has HT support too.

**xdan** · 10-22-2009, 08:43 AM

Does anyone know when 32nm CPUs are hitting the shelfes?

ill take a guess at feb~

Actually even sonner... January 3rd... I hope that Intel will count the holidays and hurry the launch to 20th december...I mean samples are for 2-3month aviable so ...

And the prices might be a little lower than suggested until now

The slowest of them all will end up branded as Pentium G6950 and this dual-core will have only two threads enabled. It runs on 2.8GHz and has 3MB memory, while LGA 1156 is the socket of choice for it. When it launches it will sell of $87.
The slowest Core i3 530 works at 2.93GHz has two cores and four threads in hyperthreding, 4MB cache and will sell for $113 when it launches on January 3rd.
The faster iteration is Core i3 540 that shares the same spec but 130MHz boost will cost you additional $20 or $133 total.

http://www.fudzilla.com/content/view/16049/1/
These sems to me like E8xxx ad E7xxx prices. i3 530 has a very good price.
I expect i5 650 to cost 166$(E8400), 660 186$(E8500) and 670 266$(E8600).
The difference between i3 and i5 will be turbo and AES instructions(i3 will not have them)....AES are some new instructions for winrar, winzip an may be some encoding. With these instruction i5 will almost catch X4 in these aplications.

I dont understand why intel are not releasing 32nm quads before sandybridge. You would think that they would be desperate to get all its range shunk to 32nm.

**xdan** · 10-22-2009, 11:02 AM

Probably Sandy bridge is more than 32nm shrink for budget quads, it has more performance tweaking like Conroe-Perynn.

**Anemic** · 10-22-2009, 11:31 AM

Looks promising!

**Ozzfest05** · 10-22-2009, 11:35 AM

4g with 0.8V

4 ghz with .84 but 4.7 at 1.43 volts I will wait for more results before drawing conclusions
I have seen E8400's at 5ghz on air

**villa1n** · 10-22-2009, 12:09 PM

I think the bigger implications are for the mobile segment.. I mean 4Ghz on .84... is ridiculous, I ll take a 3.5ghz dualcore with smt at .7v / .65v with speed stepping on a laptop any day!!!

lol curious too cause that would be amusing why chips can't beat a what 3 year old chip?

**Manicdan** · 10-22-2009, 01:20 PM

with laptops, it feels like the best 65nm were not much worse than the best 40nm, 32nm better bring a whole new level of perf/watt or ghz/watt

PRIME stable and 2M are different things.................

show me ONE Wolfdale that could prime at 4.7GHz ..... i remember one guy cheating here opening his windows in winter in Canada somewhere or US saying he could get his chip 4.6GHhz stable from memeory

4.7GHz prime stable on "normal" air with Wolfdale is unheard of

hmmm mine is an i3 iirc but it has HT & Turbo

i gotta double check

**Monstru** · 10-22-2009, 02:56 PM

Well, I actually benched E8400 at 4,9 on air, and E8600 at 5,something. My colleague Poparamiro had an E8600 that did some Pi 1M at 5,3 if I remember that right. However, none of this chips would Prime at 4,6-4,7 on air. And those were good chips. I can't say that this is a "gem" i650 or anything like that. I think that once more mature bios-es hit the market, and more and more people start showing results with these babies, we will be able to know for sure what is an "average" Clarkdale stable frequency on air. For now, the start is very promising and I have to take my hat off to Intel

i guess you dont hear much lol

i been @ 4.6 24/7 prime stable all summer and soon to be @ 4.8 for winter on air lol

**dinos22** · 10-22-2009, 03:28 PM

^^^^ oh yeah this is that guy

me too i've had CPUs capable of doing 3dmark06 at 4.9 but priming was a different story....

Me too.

That's my 24/7.
Ran it 5.0 on the old I45 - that's around here somewhere.

well thats easy

some now know

but they they satisfied with a slow laptop for 24/7

i only primed @ 4.8 i will try higher

well as saya explained to me, intel has no need for 32nm quads there 40nm's are selling well the fab is paid off so there making the chips for little to nothing atm

**Monstru** · 10-23-2009, 01:25 AM

Hey guys, thhose are some sweet valids and Pi SS. I can play that, even with my old C0. But that does not mean this is done on air and it does not mean this is prime =))

Yep, Jan 3 for Clarkdale and Arrandale.

(1) Just because 32nm Westmere quads have not been ANNOUNCED by Intel on any roadmap does not mean they won't make them... why crap all over current i5 quad sales when they don't need to?

(2) 32nm will only ramp so fast, and there'll be a LOT of Clarkdale and Arrandale volume, plus Xeon (tho that last is a small part).

(3) It could be that Sandybridge is looking good, and will make a late Q3 intro, in which case, together with (2), might not be a large enough window to justify 32nm westmere quad.

(4) They want to use the 45nm fabs for *something*, and with AMD non-competitive, why NOT keep selling quad 45nm desktop parts until Sandybridge? Higher material cost per die, BUT the 45nm fabs are "paid off" vs 32nm, so it is unclear which actually benefits them more.

So... a bunch of possibilities
