Anandtech Review of Ivy Bridge is Up now! Other sites added

[Kenmitch]

Wow. The "forum preview" nailed this guy. The reviews are offering very little in the form of new information. (IMHO)

I am glad I snagged that 2600k from MC, even though I have yet to open it...




Definitely. If the bundle is right, well... buying now is the sensible thing to do. Wait too long and Haswell will be too close... and that might bring the IPC gains that really move the goalposts

It's gonna shine in the mobile world forsure.

For the casual overclockers it'll shine also.

For the never ending quest for speed....It's gonna be a flop!

For the aftermarket cooling market....It's gonna be the best test bed

 

[exar333]

No offense but even review editors are noting how much more difficult IB is to overclock compared to sandy bridge. The plot graph at this very site shows a 90C temperature at 1.25V and 4.5ghz....I guarantee that SB would have better results than that. Heck, my 2600k does not exceed 60C at 4.8ghz. That is heavily overvolted as well.

Overclocking isn't guaranteed for any chip, obviously. IB is better if you dont' care about overclocking.

Guru3D had really good things to say about their OC. They got ~4.9 with temps spiking just below 80C (average). That was 1.392v with the stock cooler. Maybe a 'cherry' CPU? Temps are high, but that's a great result with stock everything...

Those temps are really good @ that voltage compared to Anandtech (cheap water) and [H] (big water)... Hmmm... brief article. Wonder what would happen if they hit it with a wider array of stress tests? Ideally, something with AVX. Maybe not super real-world, but definitely a burner....

 

[pelov]

Has the TJmax changed at all?

 

[Termie]

Kyle at [H] was clever and did an IPC // OC review. Worth a read. The IPC is a bit lower than I was expecting and it looks like it'll be easier to offset that with the higher overclocks you'll get with SB.

This is definitely a laptop chip from an enthusiast's perspective.

Wow, showing 2-7% IPC improvement: http://www.hardocp.com/article/2012/04/23/intel_ivy_bridge_processor_ipc_overclocking_review/3

That's quite minimal, and probably not enough to make up for the lack of OC'ing headroom.

 

[BD231]

Should be pretty funny watching all those water cooling lunatics get stuck at the same clock speeds air cooling provides.

 

[blckgrffn]

From this:

After how disappointing chilled water has been going from Phenom II to SB, I can't wait to get a hold of an IB chip just so I can have a leg up on those silly air coolers!

Haha!

I think you've got it right, BD, but it is going to be fun to hear about anyway

 

[darkxshade]

Seeing that the 2600k went on sale for $200 from MC, with the release of IVB, any chance we could see discounted 2500k... and I don't mean the $180 it is now from MC, more like $150 across retailers?

I'm glad they did the IPC benchmarks because it's not something most bothered with, including Anand. VR-zone also did them and over a larger variety of workloads and it's a mixed bag -- anything 0.0 to 15% with a vast majority in the low single digits. I think people were definitely overstating the IPC gains.

http://vr-zone.com/articles/ivy-bridge-vs-sandy-bridge--4.8ghz-quad-core-cpu-showdown/15637.html

It looks like if we're to take into account both sites' benchmarks, the IPC gains can potentially be offset by the higher overclocks that SB is more likely to achieve. The TJmax is 105C on IVB but I don't think anyone wants to reach the 80+ marks so the real enthusiast benchmarks are going to be a matter off max potential OC with cooling that isn't closed-loop water setups -- something like a hyper 212+ on both and seeing just how they fair. It's looking like an overclocked SB matches an overclocked IB, and if you happen to have better cooling, will probably surpass it as well.

I think that, given that the enthusiasts are the ones who read these reviews and buy those chips (broad over generalization, granted) that there is no reason for the 2500k or 2600k to go on sale right now.

For the enthusiast set, the difference between IVB and SB is going to be minimal.

As pelov put so well while I was typing

 

[MPiland]

Ok, my question is this...as someone who does 3D applications mainly and some gaming when I have time, is this a good buy or should I just stick with the 2600k? Now, I don't have either right now, I have a box just waiting on a CPU. The box has the Asus p8z77-v pro mobo, 16 gb of dual channel ram, dual GTX 560 ti cards, and an H100 cooler. So should I stick with SB since I don't have a PCI 3.0 card? But what if I want to get dual GTX 680s later (the 560s were free from a friend)?

seriously, i think that even enhusiast don't really wanna spend 200+ buck for this kinda of "upgrade"

 

[Don Karnage]

If you have a 2500K over 4.8Ghz you should be even with a 4.5Ghz 3570K

seriously, i think that even enhusiast don't really wanna spend 200+ buck for this kinda of "upgrade"

I did. I went blindly into it with no results to go off of and i don't regret it. My only regret is not getting a 3770K from the start

OC or no? If not, IVB is the way to go, I don't think there is any question.

H100 has OC written all over it though Even then, if IVB is ~ the same price as a 2600k, I don't think I'd take the 2600k. Now, if you can save some reasonable $$$, I think the 2600k is a pretty attractive option...

I was trying to say that you would unlikely be able to tell the difference with decent oc's on both. Once you have to touch the voltage, IVB appears to quickly surrender its power efficiency and temp lead.

OC for sure lol why even get a H100 if I wasn't going to OC. I haven't seen a price drop for the SB (missed the MC deal) so I'm still leaning towards IB. Like Don said, a 4.5 IB should match a 4.8 SB, right? Oh, BTW, I'm going for the 3770k if I do go IB vs the 2600k SB.

 

[Don Karnage]

IVB appears to quickly surrender its power efficiency

55w difference between IB and SB at 4.8Ghz

 

[Smoblikat]

Reading the reviews, IVB is nearly identical performance wise to SB, but it does so with less power and slightly higher temps. But what i liek about it the most is that it allows for high clocked DDR3, and its incrementally increased by 200 instead of 266, which means we can get to DDR3-2000 and 2200 without having to go to 1866 or 2133, reading the hardware canucks review it says that it takes less voltage for their IB chip to hit 4.7 than it did their 2600K. I understand that its all a silicon lottery, but thats somthing of note.

In conclusion, based on what ive read I would call IVB a sidegrade to anyone who currently has SB, but if youre looking to upgrade from somthing older then IB looks to be a very promising solution.

They are still on sale @ MC, $280 all day every day, 2700k is even right there at $300...

Not so sweet as $200, no, but still solid. Especially if you pick up a bundle motherboard and flip it.

Z77 may have made that harder now, but it is still an option.

55w difference between IB and SB at 4.8Ghz

*snip*

Well now, that looks good. Do we have the respective voltages at those clocks?

That makes it look like we can save 10-20% power at the same clocks needed for the same/better performance based on the IPC gains? That is certainly worthwhile *given* that it scales up into the over clocks.

Especially for those looking for 24/7 loads...

http://www.anandtech.com/show/5763/undervolting-and-overclocking-on-ivy-bridge

I wish they would overlay an analysis of an SB chip with their findings here. That is what I was basing my comment off of. Their chip at 4.8 Ghz looks like it would be a burner... @ 1.3+ volts.

 

[BallaTheFeared]

Should be pretty funny watching all those water cooling lunatics get stuck at the same clock speeds air cooling provides.

lol if I can hit 5.3GHz on Ivy I'll be the one laughing.

Considering how close dons 4.5Ghz comes to my 5.2GHz scores it would be pretty nice.

It's a 'tick'. What else did you expect?

But I don't live near an MC per se and that price is in store only, so that doesn't really make it worth it to me.

This is probably the best IPC gains from any die-shrink 'tick'. Definitely solid. If anything was over-stated, it was the OC ceiling. This didn't come from Intel though, the official information released regarding IB appears to be pretty accurate.

 

[exar333]

Personally, I am excited to see what IB can do with 8-10C ~4.2-4.4ghz. If the volts can stay low, you could get some AWESOME performance with a much smaller die vs. SB-E.

 

[Subyman]

Seeing that anandtech was able to run Ivy at 1.1V @ 4.4Ghz at 65C, that seems like a fantastic sweet spot for a daily build. We hear a lot about people jacking their 2500k's to 5Ghz on air, but not many are able to run that daily.

I'm happy with my 2500k, but I think that Ivy has turned out great. I'm glad to see them go the power saving route for this build and include a damn fine graphics chip for the lap top and budget gamer crowd.

BTW, any full loop watercooling reviews yet? I have my 2500k on a Raystorm/EX360 loop and am interested in seeing how it OCs with a proper cooling solution.
