Haswell Virtualization Question

post #1 of 7
Thread Starter 
Hey everyone! I was wondering if I can run something by you guys. I am getting ready to go to college soon and will be going for computer programming so I want to get my computer as powerful as I can so hopefully it will last most of my college years. I was looking at getting an i7-4770k for the overclocking abilities if I needed to later on but I just learned that it doesn't support VT-d. This concerns me since I will most likely be running HyperV machines. I see that it does support VT-x, but I want to be sure that I can run virtualized machines well. I currently have an i5-760 and it also doesn't have VT-d, but I am curious if having will improve performance.

Thanks in advance and for reading all this! smile.gif

Edit: Out of curiosity my i5 still feels fast to me, but will there be a noticeable overall improvement with a new i7?

VT-d only matters if you want to have direct access to hardware on the VM it does not improve VM performance for typical VMs. what it can do is for example passthrough a graphics card to the VM so they VM have direct access to it and offer full performance gaming inside a VM.

also note that Z87 platform does not officially support VT-d however asrock is known to continue to offer vt-d despite not official

tbh overclocking is overrated, little to be gained compared to whats lost and the overhead is so tiny its barely worth it without extreme cooling or extreme measure to delid

Okay! So in general I should be just fine with a 4770k? And should a Z87 still work ok for me since my 4770k wont support VT-d anyway?

The 4770 will support VT-d, but the K doesn't. I'm running into the same issue upgrading from my 920. The non-K isn't exactly the best for OC though. Instead of a VM you could just use a small Linux partition for your programming. In our labs we were mainly Linux for the CompSci department, so you might call your advisor/professor/department and find out what they're using for the classes/labs.

You plan on using HyperV over Xen and VMWare programs? doh.gif

But others already mentioned no VT-D on K series CPUs only VT-X. If you don't plan to get a K series I would look into getting a Xeon.... if Intel plans on releasing a 1150 compatible chip. i7 for the price of an i5, I wouldn't expect anything from a Xeon in the overclocking department though I'm pretty sure the multi is locked down.

I probably will have Ubuntu installed as well, but I usually do all my work on the Microsoft platform, that's why I'm wondering about HyperV. thumb.gif

And yes, I probably will use HyperV whenever I can. It is built into Windows 8 so I don't have to pay for it smile.gif and plus I have always gotten better performance using it. VMware seems to lockup my host system too often, probably as a result of not having SSD's, but HyperV works well! If I went with a VMware solution would it still work smoothly without the VT-d support on regular hard drives?

I will also use this computer for gaming purposes as well. Will Xeon work well with that? I have always seen Xeon in servers (hence the VT-d support I suppose)

From what I've been hearing you'll want the VT-d support for VMware, it's pretty buggy without it. Hyper-V would be fine for what you're doing anyway, plus free is always good thumb.gif
