techreport.com — The Tech Report put Intel's "Woodcrest" and quad-core "Clovertown" Xeons up against AMD's Socket F Opterons in a range of applications, including tests from fields like computational fluid dynamics and proteomics. They've also quantified power efficiency in terms of energy use over over time and energy use per task, with some intriguing results.

That AMD chip still isn't 65nm. Sort of like comparing the latest ATI or Nvidia card (whoever has the current lead) vs. the competitors previous generation card. I would hope that the Xeon would be faster.

Not it is comparing what they have on the market, NOW that you can purchase, not those systems that or in the not so distant future that will always be just around the corner.

Sorry, I linked to the wrong information. The Xeon 5100 (Woodcrest) is based on Core 2 (Merom and Conroe), which is based on Core (Yonah).<a class="user" href="http://en.wikipedia.org/wiki/Intel_Core_2">http://en.wikipedia.org/wiki/Intel_Core_2</a><a class="user" href="http://en.wikipedia.org/wiki/Xeon#5100-series_.22Woodcrest.22">http://en.wikipedia.org/wiki/Xeon#5100-series_.22Woodcrest.22</a>

This has been the case for a while now, as the AMD64 architecture revolves around the integrated memory controller, which cuts down quite a bit on DRAM-to-L2 latency. While this is a great innovation, it doesn't mean a whole lot in the end if your processor isn't doing enough work to keep up with its magnificent memory management.It'd be very interesting to see what difference it would make if AMD removed the memory controller from their chips, or if Intel added one to theirs, to see how much latency actually plays into current workloads. If I had to guess, I would say not a lot except for in certain gaming situations, but I've been surprised before on benchmarks like this..

Maybe you're thinking about the Itaniums ... Dell and HP have ditched them in their servers and Intel has cut production of about 8 of them so ...
