Intel Xeon E7 v2 - Ivy Bridge-EX / Ivy Town Release - Ask me!

[Patrick]

For those that are following, Intel released the Intel Xeon E7 v2 series today for dual, quad and octo socket servers.

My coverage:
Intel Xeon E7 v2 Takes On IBM Power, x86 and Oracle Sparc - Up to 15 Cores and 8+ Sockets
Intel’s Skip-Tock Unveiled Intel Xeon E7 v2 Released

I had the opportunity to join a day long press briefing on the new chips about a month ago along with a dozen or so other journalists so there is quite a bit behind all of this.

Feel free to ask away!

Twice as many cores as my Xeon E5s - check!
Bigger cache - check!
LGA2011 with PCIe3 - yup!
Will work in my Supermicro quad system - hopefully!
Greater memory bandwidth - They say the increase is "massive". Any numbers to share Patrick?
Only 3 QPI - Huh?
Only 32 PCIe3 lanes - Wha-What? That's a bit skimpy for 15 cores. E5's have 40 lanes for 8-12 cores.

Now I just have to wait until reasonably priced ES versions appear on eBay. I won't hold my breath.

I do not think they will work with the G7 since HP released the DL580 G8 today :-/

The chips have more memory channels and PCIe 3.0 directly from the chips (32 lanes each!) so I think they needed a new socket, much like Westmere-EP to Sandy Bridge-EP did.

I will grab some slides on performance later. But 2x in most applications. If you need I/O a 4S system has 96x PCIe 3.0 lanes and if you are memory hungry the performance goes up too.

My biggest question is which socket are these being released for, because I doubt that LGA2011-13 will support it, because that is already slated for Haswell-E, but could it be LGA1567? I hope it is not LGA1356. :/

(IF I glossed over the socket having been declared, I apologize.)

 

[Patrick]

Listed as FCLGA2011 but I think you are right, this may be another LGA2011 rev.

 

[Patrick]

Ok confirmed. There are going to be at least 3 different LGA2011 sockets: One for the E5-x600 v1 and v2, One for E5-x600 v3 and one for the E7 v2

 

[MiniKnight]

Wait so LGA2011 is going to refer to three different sockets? Why couldn't they jus add or subtract nominal pins like they did with LGA1356? Confusing.

Does that also mean that you can't put a Haswell-EP into an existing LGA2011 motherboard?

I think Mobo's are different

Single socket CPUs
Dual Socket CPUs
Quad Socket CPUs
and Octo Socket CPUs

I take it a Xeon E7-8890 v2 Octo socket CPU will NOT work in a single socket LGA2011 mobo ?
Single/dual socket v2 CPUs should be interchangable with a BIOS update but as we've seen before it may not
