Preliminary specifications of Intel Xeon E7v3 (Haswell-EX core)

[ahhming]

Built on Haswell-EX core, will incorporate  improvements as increased number of cores, larger L3 cache, new AVX and TSX instructions, along with added support for DDR4 memory.
 

Xeon E7-4800 v3 line will be comprised of E7-4809 v3, E7-4820 v3, E7-4830 v3 and E7-4850 v3 SKUs, that will have 8, 10, 12 and 14 cores respectively. Since each core comes with a 2.5MB slice of L3 cache, shared between all cores, the total size of L3 cache on the chips is going to range from 20 MB for the 8-core processor, and up to 35 MB for the 14-core one. The CPUs will operate at 1.9 GHz - 2.2 GHz depending on SKU, and will fit into 115 Watt power envelope. In addition to 4 SKUs, one of the documents mentions off-roadmap Xeon E7-4857 v3. If released, this CPU will have 12 cores, 140 Watt TDP, and it will be clocked at 2.5 GHz.

 

 

Xeon E7-8800 v3 series will have mostly 16- and 18-core models, with a couple of exceptions.The Xeon E7-8893 v3 will have 4 CPU cores, 3.2 GHz clock rate, and 140 Watt TDP. The E7-8891 v3 will have the number of cores increased to 10, and clock speed reduced to 2.8 GHz.



16-core Xeon E7 v3 models are E7-8860 v3 and E7-8867 v3. Clocked at at 2.2 GHz and 2.5 GHz, they are rated at 140W and 165W TDP. The documents also mention Xeon E7-8857 v3 SKU, that has identical specs to the E7-8867 v3.

 

Xeon E7-8870 v3, E7-8880 v3, E7-8880L v3 and E7-8890 v3 have 18 CPU cores and 45 MB of last level cache. Base frequencies of these models start at 2 GHz for E7-8880L v3, and go all the way up to 2.5 GHz for the E7-8890 v3. The low-power E7-8880L v3 has 115 Watt TDP, which translates to a bit over 6W per core. Other SKUs are rated at 140 Watt and 165 Watt TDP.

Wow, probably the hottest CPUs since Core 2 Extreme (Wolfdale).

[dadasmithywinkle]

-snip-

Are there any new Haswell (1150) Xeons coming out or only Haswell-E (2011-v3)?

[That Norwegian Guy]

The 8891 could be a good balance.

[KungPaoChino]

All these cpus I cannot afford. looks like I need to dig deep and grab some money from my scholarships

[Syntaxvgm]

I would really buy these if they were unlocked. They are well binned, and I would want to push the clock rate higher for certain usage. I understand that in servers stability is king, and the draw of the enthusiast ones is the overclockablility and base clock rate, but xeons are more expensive....and you don't need to touch the multiplier in a server system (use at your own risk)...sooo...why not. 

The problem I have is that I can't throw i7's into a multi cpu system. So if I want unlocked CPUs in a system with more than 8 cores, I'm fucked. I feel there's a gap, and given the binning of xeons, I would be willin got pay a premium for xeons if they were unlocked. 

[geforceftw]

 E7-8880L v3  at 5GHz. Linus do it please. LN2 it up lol.

You forgot the AMD FX 9590 sitting at 220W, and IBM's Power8 which sit at 195W.

2011-3 only, to the tune of several thousand dollars each.

you can always commit to buying hundreds of thousands of cpus, and intel will configure a custom SKU for you

[Tech_Dreamer]

Awesome! B)

[wpirobotbuilder]

Sadly these are 4 and 8-socket models. Only supported by special motherboards (can't put them in an x99 or dual-socket board). Sadly, we can't purchase these CPUs or motherboards easily.

 

The TDP of the 8893 is surprising given that it only has 4 cores. Then again it has a massive amount of cache per core.

Really? That would be awesome!

You can put the EX ones into C612 boards no problem... and some x99 boards should support them too.

 

and yes, most OEMs have their custom SKUs from intel

They can? Most boards I've seen only list compatibility with the E5 series, not the E7.

You can do some really impressive BCLK overclocking with the Xeons. Well over 110MHz is easily acheived.

Probably in a future BIOS update. I wouldn't be surprised if the WS would take a E7.

Whoops i was wrong, apparently EX isnt electrically compatible with the usual sockets (or atleast it wasnt so far, we shall see with haswell EX)

[Bsmith]

18 cores, 2.0GHZ, 115 TDP, 45mb cache, damn seems like yesterday people where screaming for 8core xeons and now we have this

[MrSuperb]

and it would be a total waste, because basicaly you just pay more for the extra QPI links.

There are only server motherboards with more than 2 sockets to use those QPI links.

There is no desktop operating system that allows the use of more than 2 CPUs (other than some linux distributions)

[MrSuperb]

in theort you can have a server with 144 haswell cores clocked at 2.5 GHz.

price? don't ask.

[multifrag]

And I'm still sitting here with 2x Xeon 5540

That kind of money mibght take a bit of overtime pay lol

I'm aware of that, but it's still not much of an increase, and base clock overclocking really adds in instability for stuff like pcie devices that can be difficult to tune just right. Hell, n some cases if you push it far, it can be 100% stable but the iGPU wont work. My desktop's iGPU wont work at all with a base clock increase of just 1 or 2, but I can push it to 107MHz otherwise.  

I would much rather raise the multiplier

25*110 would yield 2750MHz. for a Xeon that would help the workload. They don't really need unlocked multipliers. The TDP is high enough for Intel already.

This wouldn't be for a server, it would be for a workstation. Cooling is not an issue there. It's not that it would be needed in servers, I just wish the option was there with their price range.

Their base clock raises so high  due to the binning for xeons. Imagine if they were unlocked.

Well increasing the multiplier would be great. But Intel are assuming that the server and workstation guys wouldn't be bothered with overclocking.

 

Even though it might aid them.
