VT: Netburst vs Core microarchitectures

VT: Netburst vs Core microarchitectures

I'm doing a school report on Intel's Core microarchitecture and one of the criteria is too get in touch with someone at Intel or with someone in their community to answer a question for me.

My question is: I know that Intel debuted VT back with the Pentium D line. I was wondering what advantages does the Core microarchitecture has compared to the Pentium D (Netburst microarchitecture) in the field of VT?

Thank you.

Anyone?

Core Microarchitecture
delivers offers industries best native performance and native performance
matters for virtualization performance.

Core microarchitecture
delivers three major enhancements

1)
Wide
Dynamic execution engine that can retire 4 instructions per clock.
Virtualization/Consolidation is about doing more with less and being able to
retire more instructions per clock results in better
performance.

2)
Advanced
Smart Cache and Smart Memory Access provide larger cache sizes and intelligent
pre-fetching so that you do not have to frequent the memory that often
particularly when you are running larger amount of workloads as in
virtualization

3)
Power
capabilities that deliver best performance per watt.

Intel also has VT
architecture included as part of the processors that address software overheads
associated with hypervisor (VT-x, VT FlexPriority, optimization of VT Exit/Entry
latency).

Beyond this Intel
offers virtualization enhancements across the platform (such as VT for
connectivity (VMDq, IOAT) in networking devices) that reduce the hypervisor
overheads.

Also Intels Quad Core
delivers unparallel performance within a single socket and since most VMMs
licensing is socket based end customers get great performance (and perf/watt) at
lower license cost by using Intel Quad Core in virtualization

Much appreciated. Thank you.
