Disingenuous Dell and more Xeon & Opteron system wattages

Wednesday Aug 22, 2007

Disingenuous Dell vs. HP comparison? Dell has a power comparison with measured data, cool. But they try to compare three 16GB HP Opteron systems versus two Dell Xeon 32GB systems. Quite the easy way to it appear that Dell draws less power, by comparing a total of 64GB for HP and 48GB for Dell. Source:

  • 32GB 4-chip Dual-core 2.8GHz Opteron = 730 watts
  • 16GB 2-chip Quad-core 2.66GHz Xeon = 445 watts
Really memory is taking lots more than CPUs, I think memory size is more important than chip count. Prove me wrong, with data please!

Regardless, we have a few more wattage datapoints.

If Dell compared systems with the same size memories I would not have used the term "disingenuous."

you think a measly 16gb more is going to close the gap? LOL

FB-DIMMS suck lots of power. But they also compared different processor counts. I'd also like to see both at 64GB!

But what I'm mainly saying is that comparisons need to be like to like in memory size. If you look at the rest of the documentation and the math that they base all of the rest of the comparisons with it makes a difference.
