Intel Broadwell-DE Xeon E7 chips detailed; 15+ cores, 6TB memory support

[AFQ]

At the recent event in London, Intel has given further information about the upcoming Xeon E7 Broadwell-DE processors which will replace the current Ivy Bridge-EX server SoCs by the end of next year. The Xeon E7 Broadwell-DE processors will be based on a 14nm manufacturing process and will support up to 6 TB of DDR3 memory.

Damn this is insane. 6TB of memory.

 

[_Rick_]

Ah, 6TB, given 64GB RDIMMs and 24 slots per CPU on a quad socket.
But EX is a 16+ socket capable platform, so you can probably get there with less RDIMMs per CPU and 32GB sizes, which are at least available...
I wonder how all those traces will find their way onto an actual board...

So they're skipping Haswell I guess? Ivy bridge to broadwell?

Nope:

It seems there is some bad info in the article. Because Haswell-EX and Broadwell-EX is DDR4 only. And The Broadwell-DE is also an odd sudden new name. To be honest the entire article sounds pretty "homemade".

 

[Arachnotronic]

Article is wrong. Next gen E7 is NOT Broadwell-DE.

The author of the article is simply confused. These are two entirely different product lines.

 

[AFQ]

Actually, Intel seems to be introducing a new line; Broadwell-DE which will somehow fix between Broadwell-EP and EX or may be above the Broadwell-EX.

Here is some bad translation from the original source which is in German:

Behind the code name "Broadwell-DE" (BDW-DE), the Intel divulged for the first time, hiding the already revealed in July this year SoC variant expected in the second half of 2014 the first 14-nm processors.

This tells that Broadwell-DE is indeed a new name which Intel will be using for the first time. There is an article on the same German site which also says that some Broadwell-K is also in the works.

AFQ,

No. Broadwell-DE is an SoC based on the Broadwell cores for microservers. It's not EX or EP class.

SoC as in Broadwell with an integrated PCH? Or just on package PCH?

Broadwell should extend that trajectory further, which makes it potentially a very nice fit for those spots where an Avoton might do but a little more computing power would be preferable. We don't know much yet about this Broadwell-based SoC, but Waxman confirmed that it will be a single chip with integrated I/O, storage, and networking.

That's exactly what Computerbase wrote.

I wonder what that costs.. 96 sockets of 64gb DDR3 strips?

Most likely DDR4 instead of DDR3. Just to add cost as well

So you think the writer of the article is mistaken?

Considering Haswell-E/EP/EX and Broadwell-E/EP/EX doesnt support DDR3, it was quite serious with DDR4.

That would be correct, yes. He is merging two entirely separate products. Broadwell-DE is a low power, high performance version of the Atom-based microserver lineup. Xeon E7 that's on the way is Haswell-EX which is an 18 core Haswell based processor.

Nope, DDR3. The E7 is Ivy Birdge-based.

 

[ShintaiDK]

Nope, DDR3. The E7 is Ivy Birdge-based.

Where did Ivy Bridge come in?

Where did Ivy Bridge come in?

The original source.

There the reporters debate whether the (potentially) 15-core E7 has any relation with the current 12-core E5, and potentially released 12-core IB-EP for the enthusiast market.

The next ("current") E7 is the final iteration of the IB-E release.

Broadwell-DE has nothing to do with the E7 release, and Haswell-E is still a year out, let alone the EX series, which an E7v3 would be based on.

Haswell E will have DDR4, IIRC, but in this case even the Intel slide sais DDR3, and I don't think they'd get that wron.g..

The ChipLoco one was indeed. The Computerbase report was directly from the press conference though, and I would consider what information was gleaned there to be relatively trustworthy - as they simply reproduce what Intel told them, and reported that nobody wanted to answer their questions....

So, to sum up:

Broadwell-DE: 14nm SoC/SoP above Atom-Xeons.
E7: Ivy Bridge-EX, DDR3, 24DIMMs per socket max, not the same core as the E5, nor the E5 harvested from E7 cores.
