So is IB-E as good as cancelled then or... what?

[Maximilian]

think i already saw confirm of 3970x on vr-zone or legitreviews. however all i saw was a 100mhz bump and then a bump of tdp as well????

Indeed you did, i saw it at toms earlier.

Proof?

Could I lay claim to precedent? The 775 chips (although they were differing architectures on the same Socket) and Socket 940 seem to back this up.

That said, the X79 chipset doesn't have native PCI-E 3.0 whereas even basic Z77/IB does. Admittedly it's speculation, but if IB-E is released at the cusp of Haswell then it might make sense.

Still I doubt haswell will take to LGA2011. It would be great if it does though. I'd say it's going to be another LGA1567 kind of deal.

Haswell-EX/EP have already been confirmed to use DDR4. That alone means you won't see them on LGA 2011. Haswell-E will just be a rebadged EX/EP CPU, so it won't be hitting LGA 2011.

Allowing for multiple architectures on the same motherboard isn't as simple as it was back in 2006. Core 2 and NetBurst could work on the same motherboard because communications with components were handled by the Northbridge. If the Northbridge could work with the CPU (they all used a front side bus), then it could work on the board.

Today, motherboards don't really have a Northbridge. Everything it did is on the CPU.

 

[ShintaiDK]

Exactly. Thats also why we see AMD for example jump from FM1 to FM2 and no compatiblity.

 

[pantsaregood]

I actually don't know the reasoning behind FM2/FM1 having no compatibility.

AM2, AM2+, AM3, and AM3+ all support some types of backwards compatibility. AM2/AM2+ are completely cross-compatible (given BIOS support), and the same applies to AM3/AM3+. Some features present on AM2+/AM3+ are disabled on AM2/AM3, but they generally don't inhibit performance at all. AM3 CPUs only work on AM2/AM2+ because they CPU actually has both a DDR2 and DDR3 memory controller. AM3 compatibility with Bulldozer CPUs isn't that surprising, though - AMx chipsets still have a real Northbridge - only the memory controller is on-chip.

I don't know if FM1/FM2 CPUs use a Northbridge or have all of the functions integrated onto the CPU.

 

[Shmee]

I sure hope they come out soon. Any news of people getting ES's for them yet? Also, how much do we know about haswells ability to OC and support multi GPU systems? I have heard it is only dual channel as well, though that shouldnt make too much difference.

FM1/FM2 acts exactly like Intel from LGA1156 and onwards. Its a simple PCH chip only.

And AMDs socket compability have been disasterous in design terms. You sacrify performance, features and power benefits to hold onto a socket. Hence why AMD learned and now went the FM1->FM2->FM3 etc way.

 

[pantsaregood]

Performance didn't really get sacrificed. AM2+ upped the HT speed to 2000 MHz, which effectively did nothing. AM3 added DDR3 support, which again proved useless from a performance standpoint. AM3+ added some enhanced power features.

I think AM2+ also threw in intermediate states for Cool 'n' Quiet.

 

[ShintaiDK]

HT speed never mattered. I´m talking about the ability for power delivery, data traces, layout etc. Not to mention features like ondie PCIe, iGPU, FDI links and so on.

You can only do so much when you need backward compability to ancient stuff.

If Ivy-E came out in the next month or two, I might swap my chip for a little extra IPC...but it won't come that soon. This makes it a very unatractive option for me personally, as Haswell will be here soon enough anyway. I can see myself dumping my whole setup for haswell quad core since I am now an official IPC whore, but damn it I want 6 cores anyways AND more ipc. Maybe aMd will hammer the idustry with a miracle chip that lights a fire under Intel's ass?
I swear, it sucks that I can't even look forward to GPU ugrades at this point since CPU is where the bottleneck is (with my game at least).

LGA2011 does have native PCI-E 3.0, the on-die PCI-E 3.0 controller & the Quad Channel IMC what pushed the interface to 2011 pins.

I'm predicting 8 Core $999 unlocked SKU, 6 Core $599 unlocked SKU & 6 Core $319 locked SKU for IB-E sometime between Q2 13 & Q3 13. No source, just my gut feeling, we shall see

Both Z77 an X79 got PCIe 2.0.

Remember main PCIe is ondie on the CPU. Not chipset.

Also why you can get PCIe 3.0 on 6 series chipset with Ivy CPUs.

 

[Shmee]

SB-E was the first to have PCIE 3.0, actually. And yes, I believe it was on CPU die.

 

[KingRaptor]

Will Ivy Bridge-E have Quick Sync? I was kind of disappointed they didn't offer it in SB-E chips. I guess Intel feels more cores outweighs QS.

QS is part of the IGP, and the -E variants don't even have an IGP.

Quicksync comes from the iGPU. Not CPUs. SB-E dont have an iGPU.

 

[AdamK47]

People are still saying socket 2011 doesn't have PCI-E 3.0? Sheeesh!
