Early Ivy Bridge Sample Tested

[Mats]

LOL if you guys can't wait for retail 3770K at local store

http://www.ebay.com/itm/Intel-Ivy-Br...item3f164e8f7f

maybe this 3770K is special one with 77w TDP that's why it's priced that high

He didn't bother to take a pic, probably because he doesn't have a 3770K...

Please some1 tell us Intel can't have failed this much with Ivy, that people are concidering going with Sandy Bridge instead of Ivy (for those not owning a SB yet) is not a very good sight.

Will it really be lower though when starting to approach 4.5GHz+ clocks is the question as it seems that's whereabouts the temps also starts to climb quickly.

The main issue is people only see that hight temps floating around without some propper summary...

Facts:

- stock clock is now 3.9 on all cores - at least on MVG - which will beat the crap out of sandy on stock
- 1.2V will get you 4.3-4.5 on mid / low 70s with a medium aftermarket air cooler
- DDR3-2600 seems easy with the right RAM
- add the last 2 points and you get the performance of Sandy near 4.8-4.9...
- sandy just was bad ass chip on air / water showing the best out of "traditional" transistors before new 3D-gen...
- there might be a new stepping someday which will add the missing MHZ...just for the guys looking only at mhz...

The Virtu MVP feature looks usefull for increased FPS can the 2600K use Virtu MVP?

Virtu MVP is just marketing stuff.

This!

The problem is that I'm only looking/talking from this perspective:

- Maximum stable/reasonable 24/7 OCs on air
- I waited for Ivy hoping to get a noteworthy OC gain or overall performance gain from both IPC gain + overclockability combined
- The SBs will probably recieve at least a slight price drop or some users may sell their Sandys so there may be possibility to get a good deal => the lower price payed will make up for the small perf gain going to Ivy
- SB are tried n tested by this point, who knows what bugs Ivy may possibly have

With above in concideration I want to congratulate the early Sandy Bridge adopters for making a good decision, I wish I had been one of them. 5% or whatever more performance there will be for air clockers for how much more months waited? By the typical trend IPC boost may be like 5~10% for a dieshrink but better overclockability also added like 10~15% performance gain so we were more talking about like 20% perf gains. This is why I'm not that happy about it right now if it turns out to be like there's been hints of. Yes you have to upgrade at some point but it's all about to foresee how much of a performance gain a new generation will deliver that decides it for me if it was a good decision or not to wait. It feels better picking up a chip that u know performs 20% better than previous chip for similar price than buying a chip that costs similar (talking in terms of launch pricing) for 5% more performance than the previous gen.

I see a lot of talk about temps and MHz. What about the power consumption?

This!

Ivy is only 6-8% better if they are at same clock speed, if you got a 2600k chip there can 5Ghz+ there NO reason to chance to 3770K, it will be a jump down in performance.

Under load however the power savings are significant. The Core i7 3770K pulls 27 fewer watts while delivering better performance than the 2600K~~~anandtech

at 10-12 cents per KWhr even if the 2600K was run at 100% load for 24/7/365 and the Ivy used NO power at all the savings is only $100 per year

Assuming a more realistic real world stats: Loaded 25% of the time , 12 hours a day , for 365 days

idle = 2.5 watts * (.75 * 12*365) = 8,212 watts per year @ 12 cents/KWhr = 98 cents
load 27.1 watts * (.25 * 12*365) = 29,674 watts per year @ 12 cents/KWhr = $3.56

I guess you can goto McDonalds and buy a Big Mac with no fries or coke off your savings.

"there NO reason to chance to 3770K, it will be a jump down in performance. "

-unless some ib's run @ 5.0 7\24 once larger samples of batches get benched in the next few months , but of course you can always turn the 2600k up to 5.3 7\24 air?
time will tell.

There's only money in your heads.

I was looking for overclocked power consumption though. We know that it sucks less power than SB at stock, but what happens when overclocked to the max?

Well if there's like 27W difference comparing stock 2600K vs 3770K I bet there will be next to no advantage by 4.5GHz-4.6GHz, probably 5~8W or so advantage for 3770K at best. Hopefully at least some reviewers will compare OC vs OC results too.

[STaRGaZeR]

It's a completely different process that hasn't even launched, we can't make good guesses based on stock results. All this temp skyrocketing smells like PC will skyrocket too. We need some overclocked PC numbers!

Totally ignoring stuff like AC, cooling requirement for silence and so on...

Well I just boosted some games by 33%... Yeah IB sucks

[aussie-revhead]

Come on man .... we need details .... what games/clocks etc etc

[st0ned]

Dirt3 2560x1600

No magic - av_fps="77.048019" min_fps="65.490837"/>
1 button magic - av_fps="103.158409" min_fps="92.535034"/>

Same everything ( CPU clocks, GPU clocks, etc )

The main issue is people only see that hight temps floating around without some propper summary...

- 1.2V will get you 4.3-4.5 on mid / low 70s with a medium aftermarket air cooler

This!

I aggree with all except for the bold part, with IB and 1.2v you will get a hell lot more then 70s with the best aircooler there is. I would say like midle 80's. See the bright side there's no need for 1.2v to run at 4.5Ghz

[aussie-revhead]

Is that really from cpu change only? same ram and clocks too? So maybe even more to gain with new trend high speed ddr3 right?

What sort of cpu score do you get in 3D11?

[mAJORD]

I'm guessing he's talking about Virtu MVP vs no Virtu MVP

[RPGWiZaRD]

If that's the case I just want to point out MVP has nothing to do with FPS, there's a good article out there which explains it all and it's intended feature is reducing/removing input lag and tearing (Nice!). The way FPS is read is inaccurate when using MVP and the article clearly stated it really doesn't boost the performance (FPS) at all and is not its intended purpose which seems like most uninformed people are believing and therefore calling it "BS" as their games doesn't seem to run any faster despite FPS counter telling them so.

[st0ned]

It's not like CPU only, is CPU + new Z77 features

Well with this one I can go as high as >14500 in 3Dmark 2k11 with moderate overclocked 7970.

EDIT:

There are two features in Lucidvirtu MVP , one does what you say the other boost the hell out of performance

[aussie-revhead]

Stoned- is that gain all from the LucidVirtu then?

[st0ned]

Well I would have to say that here. Let's say also that it wouldn't be any CPU having these gains
