AMD BE-2xxx vs E6xxx C2Ds, power-wise?

[VivienM]

Okay, this may sound like a very odd comparison, but does anyone know of any numbers that compare power consumption of AMD BE-2xxx (on 7025 nVIDIA boards) with the E6550/E6600 (on a G33/G35 board)?

If anyone is wondering why I'm so insane as to want to compare these two: simple. I'm an Intel fanboy (with my i850 RDRAM Hotburst to prove it, among other fine Intel products I've bought over the years...), but I want to build a low-power server with hardware virtualization (VT). If I go Intel... that means going with the E6xxx. If I swallow my pride and go AMD, then I can save $80 (CAD) and who-knows-how-many-watts by picking the BE-2300/2350.

Aren't there some new VT improvements on Penryn chips? That may interest you as well.

Are you thinking of the E8200? (I noticed Intel has a VT-less E8100 too)

Hmm... that's about $10 more than a E6550... which, of course, is $140 (CAD) more than the AMD option.

One thing I was debating, if I'm going Intel with this project: I could swap out my E6600 and put it in the server and put an E8xxx (or a Penryn quad core) on my P5W DH, since apparently the P5W DH supports Penryns?!?

Hmm, I don't think the P5W DH supports 45nm. It's a shame because the E8x00 series are very power efficient.

Asus claims it does...

I must have missed it.

http://event.asus.com/mb/45nm/ doesn't list it as 45nm ready.

Neither does this page: http://www.asus.com/products.a...model=1198&modelmenu=1

Has Asus released a 45nm compatible BIOS?

 

[VivienM]

Try this page... http://support.asus.com/cpusup...t.aspx?SLanguage=en-us and put in P5W DH Deluxe

It says:
Core 2 Duo E8200 (2.66GHz,1333FSB,L2:6MB,65W,rev.C0) ALL
2504

Core 2 Duo E8400 (3.00GHz,1333FSB,L2:6MB,65W,rev.C0) ALL
2504

Core 2 Duo E8500 (3.16GHz,1333FSB,L2:6MB,65W,rev.C0) ALL
2504

Which hypervisor are you planning to use for your virtualization? If you run VMware as an ordinary application under Windows/Linux, I don't believe you're benefiting from AMD's Pacifica or Intel's VT.

 

[VivienM]

Not sure yet... Server 2008 with Hyper-V would be nice, but rather expensive...

I know Virtual PC 2007 (the non-server version) definitely takes advantage of VT; not sure about the other non-hypervisor solutions.

i am a p5wdh user w/ an e8400 and it works fine, compatibility and stabilitywise. only option you will miss is that EIST and C1E are disabled (beta bios im sure they are wokring on it)
