All the high-end processors of Intel came with Virtualization support but Intel never really equipped there lower end processors with virtualization whereas AMD on the other hand had added virtualization support to most of their processors in their line-up. Virtualization allows a user to run an operating system from within an operating system. Processors that supported Virtualization at hardware level provide better performance when/if a user runs an virtualized Operating system. Most of the users did not care for Virtualization since not many people require it and since the lower end Intel Chips were terrific overclocker, most of the people used to grab Intel’s lower end CPU’s, but all this is going to change with Windows 7.
Windows 7 supports virtualization natively and also has a feature to run *only* an application in emulation mode under a different operating system. This basically means all the people who brought the lower end Intel Processors are going to face performance issues’ when Windows 7 is officially released to the public. The shocking thing here was that even the low end quad cores from Intel did not support virtualization. Intel have finally realized there mistake and have now added Virtualization support to all their lower end processors. Here is a small image which compares the various processors from AMD and Intel on the basis of support of virtualization.
