With Intel's new Haswell processor we can verify that in no time. This number cruncher, with its AVX2 computing units, which can now also compute integers with 256 bits, as well as the two fast FMA pipelines, is predestined for that job. But watch out, even the 18-core version of the upcoming Haswell EX would still require some years to accomplish the above-mentioned task.

Anybody else wish that the "-E" chips would come faster? This is where all the fun is...

Indeed. Haswell-EX would be the successor to Westmere-EX; EX being the massive cores used for the Xeon E7 series. Intel never produced an E7 *Bridge CPU; even the planned 12 core IVB-E CPUs are merely E5s and still smaller than what Intel is apparently going to do with Haswell-EX.😱

That's so far away though. The successor to the current Xeon E7 based on Westmere EX is Ivy Bridge EX, coming in Q4 of this year. It has 15 cores.

Now based on that imagine how long it'll take for the Haswell EX to come out.

I will be an old man by then...geez!
 
I often wonder if by the time Multiparallel hits software - if for us gamerss it'd be more worth it to just say fuck it.

Get a 4 socket server - get the highest clocked xeons and some top of the line dGPUs and just upgrade GPUs for atleast 6-8 years.

18 Haswell cores? Holy moly. That sucker is going to be huge!😱

It will be probably larger than regular 37.5x37.5 package but I guess not much.
Tilera is making 50 - 100 core CPUs since 2004 for special applications, Intel is way back😀

You would be severely CPU bottlenecked.

Servers lives by concurrent users. Desktops dont. Most server software as such as actually singlethreaded if you like.
 
Isnt one haswell core merely 25 mm²? If so then they could easily fit 12 cores (24 threads) on one 425mm² die. I dont know how or why they would want 18 cores...

The core is around 15mm2 if I recall right.

This is for EX CPUs only. And the starting price for maximum cores models starts at 4000$.
 
Haswell-EP sounds more interesting to me. Up to 14 cores well before Haswell-EX (and likely at higher clocks). 18 cores is insane though.

yeah i think thats a typo.

i dont see any 18 core on the lineup.

i know the FPGA version of -E will have 15cores.. but thats the largest ive seen.
 
Westmere-EX is a 10-core CPU, Ivy Bridge-EX 15-cores. Its not strange that Haswell-EX could have 18 cores.
 
IVB-EP up to 12C
IVB-EX up to 15C

HSW-EP up to 14C
HSW-EX up to 18C


No surprise. Impressive numbers though. Huge core count increases with IVB and followed from HSW.
 
Due out this quarter: (Q2 2015)

* 2.1ghz 140w
* 2.3ghz 140w
* 2.0ghz 115w
* 2.5ghz 165w

Still waiting on CPU spec pages & pricing, but the VM possibilities are amazing! Especially with the new NVIDIA GRID K2 cards. Supermicro has a couple systems out, one that supports 4 GRID cards & a Blade setup that supports 30 hot-swap NVMe or GRID cards:

Excited to see what you can do even with Hyper-V & whatnot. The upcoming specs for the new RemoteFX look great: (2016 for Windows Server Next & Win10 Enterprise clients)

Prior to the Windows Server Technical Preview, running a virtual machine on Hyper-V limited you to OpenGL 1.1 with CPU acceleration and no support for OpenCL regardless of the presence of a capable GPU. This was a limiting factor for delivering a virtual desktop for users with applications such as Adobe Photoshop, Maya, Blender and Houdini which require these APIs. With a capable GPU on a Hyper-V host, RemoteFX vGPU now delivers support for OpenGL up to version 4.4 and OpenCL 1.1 in a Windows virtual machine.

....

In Windows Server 2012 R2, the RemoteFX video adapter has a limitation of 256MB for the maximum amount of dedicated VRAM it exposed. The amount of dedicated VRAM is also tied to the number of monitors and resolution. For the next version of Windows Server we have decoupled this and allowed increasing dedicated VRAM without assigning a specific resolution or number of monitors.

In addition, the 256MB of dedicated VRAM reported by the RemoteFX adapter resulted in some applications limiting features or disabling hardware acceleration. This was due to insufficient dedicated video memory. For instance, Adobe Photoshop requires a minimum of 512MB to enable hardware acceleration – this feature meets the VRAM requirement for these applications.

The RemoteFX adapter now provides two capabilities in regard to VRAM:

A larger dedicated VRAM amount (currently up to 1GB) – A VM can now be configured to obtain up to 1GB of dedicated video memory. Depending on the amount of system memory assigned to the VM, this can provide up to a total of 2GB of VRAM (1GB dedicated and 1GB shared)

A gig of dedicated VRAM & OpenGL 4.4 in a remote virtualized environment? Yes please! Desktop VDI is going to start getting serious, especially with all of the upcoming tiny Cherrytrail & low-power Braswell computers that will be coming out! It will be awesome to buy able to build stuff like a simple box with a single 18-core processor & have some horsepower to deliver a really good end-user experience!
