More likely they all have it, but it's disabled on-chip in non-Apple cases, isn't it?

thanks for this article. I wish I would have found this one BEFORE i bought my new Dell Studio. I am totally disappointed by the fact that I have a 64 bit capable Intel Core Duo Processor, that does not support Hardware Virtualization and it was nowhere stated in the specs on the Dell Website.
I will have to give that thing to my girlfriend and by a new machine.
Thanks for the tip with the Mac Mini's. That is actually a great idea. Let me see what they cost nowadays……

[...] most 939 processors and even some 754 processors support VT in their own fashion. Furthermore: A Concrete Reason Macs Beat PCs: Intel VT – Stephen Foskett, Pack Rat [...]

Macs are the same as PC's because they run the same hardware. Cheaper CPUs have no virtualization support so Macs just use the ones that do have that support.

Yes, PC BIOS often lets you turn VT on or off. But you can't enable it if it doesn't exist, and there are a large number of Intel CPUs (including the P7350 and P7450) that simply do not have VT support at all. These are very popular chips and are used in lots of PCs.

The amazing thing is that Intel made special P7350 and P7450 chips just for Apple which do have VT support. This is different hardware with the same name!

I suspect, Wes, that it has to do with the price and quality of the PC. Some PC models will be VT capable just like some are Areo capable. That is often because they are Pro machines, rather than consumer models.

The problem is that this capability may not be readily apparent. Microsoft / Intel might be getting another black eye when System Seven is released. Many people will be irritated because their recently purchased computer is not VT capable. Hence, it cannot run windows XP in virtual mode.

Are you quite sure about this? My two year old PC supports VT. Most PCs allow you to cut this support on and off through a setting in the BIOS.
