Haswell EP details inside!

[Arachnotronic]

14 cores. 35MB L3 cache. 4x DDR4 channels. Integrated Voltage Regulator. I assume 14 cores is derived by 35MB total cache/2.5MB/core

So DDR4 is confirmed fro the EP platform atleast. But look on those speeds. All down to 1333Mhz. That doesnt sound like a big confidence in DDR4 in terms of density/speed from the start.

Else integrated VRM like all Haswell CPUs, one of the major revolutions. I wonder what the poor mobo makers will do.

Only shame is no simple GPU. Either in the chipset or CPU. I guess we will still see Matrox G200 chips being used.

That is a bonus for me...keep those crappy IGP's of my CPU cores

I don't see integrated GPUs coming to big socket Xeons for a while.

And 1333 is not a real DDR4 spec. Has to be a typo or something. I can wait for more legit-looking slides since I'm not in the 4S business to begin with.

14 cores should be enough for anyone. But it does seem like a funny # of cores.

Thank god are they finally getting rid of the channels with DDR4? No more single DIMM notebooks that are gimped compared to dual DIMM notebooks?

 

[MisterMac]

So we've moved 4 extra cores from the Westmere to Sandy to Haswell.



Yet mainstream i5 still gets stuck with 4 cores?

:C come on!

How much homeuser software scales beyond 4 threads?

 

[Arachnotronic]

My 4C/8T SNB still rocks for desktop use. I moved to it from my i7 980X and I'm happy.

I still love seeing the powerhouse chips, though.

Its still exactly like it is today. So OEMs can still gimp anything they like.

I prefer a HD1000 or something over a G200

The G200 is so horrible it actually affects you on the console. I wonder who at the OEMs got the great idea of using a GPU from 1998 in servers.

 

[borisvodofsky]

I don't need any more cores. give me 6ghz or give me death.

Not much of it and none it of ever will unless they start pushing out 6 cores+ in the mainstream segment or at least make HT standard on all chips.

I don't think that's the problem. It's just damn hard to write parallel software.

You cannot parallelize everything, dosn't work like that.

"MOAR CORES!!!" just for the sake of more cores is not productive...

 

[Haswell-E FTW]

Some might have an idea that any task can be broken down into different parts, but when you think about it, not many tasks are actually like that (I'm just guessing, I don't hold a degree in programming or software engineering or anything). Rendering is one of the few tasks in my field of graphic/CAD workloads that is able to utilize multiple cores/threads to a large advantage. Running with a 2600K at the moment, and it is kind of neat to open up Windows Task Manager and see all 8 threads pushed to the max when rendering.

Hence my namesake, I am eagerly anticipating what Haswell-E/EP/EX will bring to the table in about 18 months - 2 years; 4 cores/8 threads is more than enough for me right now, but as I start to move away from 2D and into more 3D and rendering, I may need a true 8 or 10 core machine.

I can't believe you sold the 980X and only went SB mainstream.

I just read the article and where does it say DDR4? I saw a DDR3-2133 reference.

 

[StrangerGuy]

Oops.

 

[Homeles]

The DDR4 specification hasn't been finalized yet... it might do away with memory channels.

You are right. Also explains the "low" DDR speeds listed on the diagram. Seems DDR4 is a typo.

So much for DDR4 anytime soon.

I'd just say it's a crappy source. No reason to get disappointed.

What do you mean they are getting rid of it? If DDR4 doubles speeds, they aren't going to cut down memory channels, so they can achieve more bandwidth. Haswell EP is going to be aimed at servers and HPC. More memory bandwidth, the better.

Same with consumer chips. DDR4 means better bandwidth for the improved iGPU. Hell, they seem to be bound already, imagine in 2015 with Skylake!

DDR4 might do away with multiple DIMMs per channel in favor of point-to-point. I don't think channels are actually going away.
