There are some laptops now on the market with Xeon processors, I am very keen to get one, not sure how good they are, I want to run lots of VMs on it. any one has used one before? any recommendations?

How many is lots?

VMs normally constrained by memory and I/O

I guess my question is beside RAM, and SSD, will Xeon provide any benefits on running lots of VMs?

If your VMs use lots of CPU then yes, potentially

Your question is hard to answer. Just like how long a piece of string is.

My reading suggests that i7 and Xeon will give you similar performance if you buy similar models, but i7 are significantly cheaper. Xeon are for servers, they support ECC memory. I wouldn't waste your money on Xeon for a laptop and development type VMs, spend it on more RAM and faster / larger SSD.

Xeon server processors tend to have a lot more cache for performance, but more importantly run ECC memory for reliability.  Can't say I've ever seen one in a laptop other than the HP ZBook series which are very nice CAD laptops.

 

Running VM's on a laptop sounds likely to be a testing or development environment where the extra reliability of a Xeon with ECC may not be so important, as long as everything is properly backed up.

The main benefit of these high end machines for vm work is disk throughput. The Xeon brand and eec are just icing on the cake. Look at the lenovo p series. Up to four pcie ssd, and if that is not enough speed you can raid them :. )

You need to know if your current mobile vm issues are caused by processor or disk bottlenecks. What kind of problems are you having?

Depends what Xeons you mean.

 

Xeons range from embedded CPUs, modifed desktop CPUs to high end server CPUs.

 

The high-end CPUs are VM monsters... e.g. 18/36 cores/threads, 40+MB Level 3 cache, 1500GB max. RAM etc..

 

But, they aren't suitable for a laptop. They generate way too much heat (150W TDP) and use far too much power.

 

Your laptop would probably only run for a few minutes on the battery, if it didn't melt first.

 

It would be possible to use a Xeon that is similar to an underclocked Core i7. But, it will still use a lot of power.

 

If you really needed something with that much power in a semi-portable form, then you could build system in HTPC/Media PC case.

 

ASRock make a mini-ITX motherboard (X99 Chipset) that can take recent Xeons. i.e. ASRock's X99E-ITX/ac

no really having problem, just looking at upgrade options from my old Elibook 8770w, HP Zbook 17/15 G3 and Thinkpad p50/70 that can have Xeon processor option, sounds pretty powerful. I don't do CAD stuff, i run lots of VMs at times to do testing and what not, I will definitely get 64G RAM option, but not sure if Xeon processor is worth the extra $ in my case. or it is only for CAD stuff?

definitely the desktop/server Xeon, they will cook the laptop in no time, it will be one of those Xeon® E3-1575M v5 or XEON® E3-1535M v5 or Xeon E3-1505Mv5.

The mobile xeons are only 4 core.

How much extra are they asking for Xeon and ecc compared to i7 and standard ram?

Btw Xeon can exceed 64gb if there are ram sockets avail.

Edit: the 1575 will be insane but the others will be ok.

i think the laptop support max 16*4 RAM.  

 

it is not that expensive, like extra $100-$200.

Ahh found the data sheet on those ...  http://ark.intel.com/products/93354  vs   http://ark.intel.com/products/88967

 

They look very similar to the Skylake 4 core i7's.

 

Same TDP, Level 3 cache, max. RAM etc...

 

I would think the performance would be the same at equal clock speeds.
