They're not supposed to be sold until the 29th apparently.Does anyone say whether it can be sold today or next week? Or do we just have to wait and see if some retailer decides to start selling?

3770k has hyperthreading. If aren't doing encoding/media creation its not much use to you. Not worth $100 anyway.So is it 3770k or bust? Would the 3570k serve me just fine as a mid range chip and an upgrade over my current Core2 setup?!?!

I haven't found a single review where they OC beyond 4.8Ghz. Maybe the glass ceiling does exist? Anyone find a review where they go beyond?
http://www.xbitlabs.com/articles/cpu/display/core-i7-3770k-i5-3570k_9.html#sect0In any case, the frequency potential of the new Ivy Bridge processors turned out to be below our expectations. We didnt manage to overclock them even to the same heights as the previous-generation Sandy Bridge. So, we can state that the overclocking potential of the newcomers has become worse, which may have been caused by the reduction of the geometrical die size of the new Ivy Bridge. Its overall size is 25% smaller than the Sandy Bridge die, and the computational cores have become only half the size of the Sandy Bridge cores. However, contemporary approach to processor die cooling doesnt allow increasing the heat flow density in equal proportion, which causes local overheating of some parts of the processor cores during overclocking. High operational CPU core frequencies indirectly confirm that this problem indeed exists, although the processor cooler remained practically cold in this case.
As a result, it looks like even after the launch of the new Ivy Bridge the title of the best enthusiast platform will go to LGA 2011. These processors not only boast additional features that allow overclocking them by simply raising the BCLK frequency, but also boast better overclocking potential. However, if the LGA 2011 platform seems financially out of reach, then the old Sandy Bridge processors may present a worthy alternative to Ivy Bridge. Especially, since they do not fall too far behind the newcomers working at the same clock speeds in computational performance.

So, I know we do not have any official reviews right now but what is GAF's take on these new chips? Worth waiting for if I do not plan on overclocking and going ahead and getting an i7 2700k now and just be done with it?
Well, besides overclocking, its the only way to get USB 3.0 and PCI-e 3 right?
I don't think it has native 3.0 support.Doesn't SB support USB 3.0?
Yeah, that was the original rumors and what I thought might be going on. Intel had some PR folks that tried saying it was due to engineering samples or yada yada yada.According to techreport when you raise the voltage past the stock, power consumption and the amount of heat generated go through the roof. They managed to get it to 4.9Ghz on an air-cooled ASUS motherboard.
I think you'd need a custom water cooling system to get that high.
Nope. P67 and Z68 boards have USB 3.0, just not built into the chipset. What this means is that when ASUS goes to build a board, they source USB 3.0 stuff from a 3rd party and add it on there. PCI-E 3.0 is worthless for all but a tiny portion of people, and can be found on ASRock's Z68 boards as well as the "Gen 3" ASUS boards.Well, besides overclocking, its the only way to get USB 3.0 and PCI-e 3 right?
That doesn't really mean much.I don't think it has native 3.0 support.
Doesn't SB support USB 3.0?
I don't think it has native 3.0 support.

Man, is that ever close. The two systems idle at just about the same power level and complete the rendering task in nearly the same amount of time. (The Phenom II is a smidgen quicker.) True to its lower 95W TDP rating, though, the Core 2 Quad Q9400 draws less power under load than the Phenom II.
The Phenom II's higher peak power draw is evident here, but still, AMD has shaved 30W off of the Phenom X4 9950's peak while delivering higher performance at the same time.
Because of its higher draw under load, the Phenom II's power efficiency can't quite match that of Intel's Core 2 Quads, but it comes very close.

They offered the lowest idle power consumption of the bunch and peak consumption was lower than all of the Intel-based systems with the exception of the lower-clocked Core 2 Quad Q9400.

AMD managed to significantly lower the power consumption of its platforms. However, there is still room for improvement. Contemporary systems with quad-core Intel LGA775 CPUs still boast better performance-per-watt ratio.

The load power is still higher than the Intel Core 2 Quads, but not by much

http://images.anandtech.com/reviews/cpu/amd/phenom2/980/amd-p2-980oc2.jpg
"On our sample that meant 4.2GHz with the stock cooler. Given enough voltage hitting 4GHz+ on air isn't a problem."
http://www.guru3d.com/imageview.php?image=30237
"Here's an overclock at 4263 MHz 100% stable. We boosted Voltage towards 1.575v in the BIOS and simply applied a multiplier of 21 versus a small bus speed increase of 203 MHz. Temperatures are now much higher, but really acceptable. Again, and I can't stress this enough -- we are only using a 35 USD air based Vendetta cooler here, nothing fancy."
http://tpucdn.com/reviews/AMD/Phenom_II_X4_980/images/oc.jpg
"The end result was 4.21 GHz, which is about 100 MHz below what Phenom II X4 975 achieved when it was reviewed, but still a nice result for Deneb core. Results vary from sample to sample, but we have seen most C3 Deneb cores pass 4 GHz maximum clock."
http://images.hardwarecanucks.com/image/mac/reviews/amd/phenomIIx4_980/Phenom_II_X4_980_43.jpg
"This is going to sound repetitive for those who have read our previous Phenom II reviews, but were once again were able to achieve a new highest stable Phenom II clock speed. 4254Mhz at 1.45V with enough stability to pass 3 hours of Prime 95 Blend, one hour's worth of LinX, and a few wPrime and SuperPI runs is quite impressive. We were able to squeeze an extra 74Mhz from this chip compared to the X4 975."
http://www.overclockersclub.com/vimages/phenom_2_x4_980/oc.jpg
"For the Phenom II X4 980 I was able to reach a top speed of 4.36GHz which came out to have a multiplier of 20.5x and a reference clock speed of 212MHz at 1.5v."
These aren't magical chips, either. Numerous X4 955/965/970/975s have eclipsed the 4GHz mark. Two of those quotes make note of that. Overall, a large number of 45nm Phenom II/i5 7xx/i7 8xx/i7 9xx tend to fall within the 3.8-4.2GHz range for standard 24/7. One of my systems still houses a 24/7 Q9550 @ 4.2GHz on air. The 4.4GHz C2Q you brought up isn't any more indicative of what most get, than the few Phenom IIs which have also hit that clock. Percentage of overclock headroom doesn't exactly mean much when you arrive at the similar results. Look at how i7 920s top out compared to higher end i7 9XXs, or how the higher stock clocked Intels top out compared to the AMDs (of similar stock frequency).
Well he could still buy a Z7x-Motherboard together with a SB cpu, no?
Disappointed.
I could grab an i5 2500K for 177€ tomorrow if i wanted with no hassle to finally assemble my PC, or wait a week for the i5 3570K for 5% more perf in games (@stock) at 212€+ with less headroom to overclock and, the worse of it all, much more heat.
Damn you Intel :<
My i5-2500k is at 4.5GHz. I could still overclock it a good bit further if I wanted. It is stable with a Vcore of 1.296 V and tops out at 55°C in Prime95 (using a Cooler Master Hyper 212).
Ivy Bridge is just a tick. If you hadn't already waited so long, I'd tell you to find a Sandy Bridge to hop on, and wait for the tock! As it is, you should probably hold out a little longer just to see!
USB 3.0 support is provided by third party chips on the motherboard. IVB is Intels first natively supported CPUs for USB 3.0.
I waited several month, even grabbed the famous GEN3 version of the ASUS Z68 mobo (just for IB and PCI-E 3.0 compatibility)
Now, the thing is that IB is not so much of a valuable upgrade compared to a SB, PCI-E gen 3.0 is not useful right now (i'm not running 4 GTX 680s on 3*27" LCD alright lol) and even when it'll become usefull I'm sure any Z77+Ivy combo should be outdated.
An i5 2500K at 177€ is, I think, much more interesting from a performance/price point of view.
Yes? No? Maybe? The USB 3.0 controller is a part of the Ivy chips. I wouldn't think they'd include the third-party controllers anymore. They'd be redundant.I'm buying a Z77 Mobo, so this means if I get an i7 2700k I still will not have USB 3.0 support unless I get an IB CPU? Am I understanding that properly?

A third party controller will still give you USB 3.0 with a Sandy Bridge chip. People tend to prefer it being on-die because the Intel controllers tend to be much more robust than third party chips. Don't worry about it, you'll be fine.
If you already have a z68 board, what are you waiting for?
We even had a discussion a page back about how it might be difficult to update the BIOS on a z68 board for Ivy if you don't already have a Sandy chip on-hand.
Yes. The USB 3.0 controller is a part of the Ivy chips.
It doesn't matter. Some might, some might not, depends on how many ports they want to provide.Will the Z77 still have a third-party controller though? I didn't think it would...
Yes the discussion was with...me lol
I'll grab a SB tomorrow and then my beautifull Graphite White 600T will illuminates itself with that beautiful subtle white of his <3
Can't wait ahah
or something as simple as unpacking a large RAR will take a fortnight without HT.
Wait.
Winrar does use hyperthreading? Since when?
Will the Z77 still have a third-party controller though? I didn't think it would...
it doesnt of course, no archiver uses multiplecores for extraction.
It doesn't matter. Some might, some might not, depends on how many ports they want to provide.
You may want more USB 3.0 ports. Lot of high ends mobos offer third party controllers to have more SATA or USB ports. OFC native ones will be better most of the times.
The point is, it doesn't *really* matter if they are third party or automatically included in the chipset to intel's spec. Sometimes that can mean better performance, but we're talking about USB 3.0 here, not SATA ports. If you're relying on USB 3.0 for large data transfers often, you're doing it wrong.I didn't think about Ivy itself being limited to only four USB 3.0 ports. Good point.
As long as your motherboard can do x16/x16, no need. Otherwise, why not just get a new motherboard without a processor upgrade?to get pci-e 3.0 support for my triple monitor and soon to be gtx 680 sli setup, i need to sell my perfectly good 2500k and p67 mobo, unimpressed tbh :/
Could do this or go for a socket 2011 w/ an i7 3820. I'm in the same spot as you.I need something better for video encoding. Should I upgrade from a 2500k?

You already have your 2500K overclocked past 4.4Ghz right?I need something better for video encoding. Should I upgrade from a 2500k?
3820 is 4C/8T for a bit cheaper on 2011. Still around $500+ though.That's the cheap option. You can go with a Socket 2011 SB-E mobo and CPU for 6C/12T but then you are looking at a $600 upgrade.
ThanksPCIE controller is in the CPU in Intel since Lynnfield, nothing to do with motherboard.
If you want 2x16 you need x79 at socket 2011

The PRO probably has more VRMs just looking at the boards, also some extra caps and chips scattered about. Regular should be more than fine.Jesus, why is ASUS so fucking convoluted? I mean, just look at this shit:
What's the difference between the P8Z77-V and P8Z77-V PRO?
The ASMedia® USB 3.0 controller on the PRO has an extra 2 USB 3.0 ports.
That's it. Seriously. Go do a comparison on their web site. There's nothing else different between them!
