VT: Netburst vs Core microarchitectures

rageoffury — Mon, 18 Feb 2008 15:15:05 GMT

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.

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.
