  I didn't want to believe it but you really ARE biased towards Intel! After all the harm they've caused in this industry how could you be? Do they threaten to stop sending you testing material if you don't sound like they're the second coming of Christ and AMD is just a second-rate company?

  Good article.
  
  Trying to find these to buy. AMD Athlon II x4 635 is the only one I have found available (newegg.ca). I live in Canada.
  
  Are the rest of them expected soon?

  I want to build a WHS and the 3 things I consider most important are Video Encoding performance, Low Power, and Price. That being said I have narrowed it down to Athlon II X4 vs Core i3. A matchup I would love to see would be an undervolted Athlon II X4 vs. an Overclocked Core i3. If not then maybe everybody could tell me which they recommend?

  for the video encoding part, that's easy enough - just check out "Bench", and factor in your underclocks and overclocks, since encoding scales fairly well with clock speed for a given cpu.
  
  Price is easy enough to figure out.
  
  The i3's probably have the best power/performance.

  As a fan of silent computing, the 45W TDP quad-core 910e is the most exciting chip in this round, and I don't see it in the power consumption graphs. Disappointed.. :(

  You see in the charts that:
  - idle power isn't that much different between the AMDs
  - at load they consume about their "ACP" (former TDP)
  
  So if you're not running under load the choice doesn't matter. If you run under load you could take any of the current 45 nm CPUs and lower its ridiculously high stock voltage of 1.4 V to maybe 1.2 V at 2.6 GHz. That should get you to maybe 80 W instead of 65 W for the specially binned chips. Close enough I'd say. If it's still too loud: go to 2.5 GHz and lower the voltage again.
  
  BTW: Core i3/5/7 can be even more energy efficient if you don't push them to 4 GHz.

  ACP that AMD use now not very helpful 95w/65w may had just be 125w/95w,
  
  the Athlon II are far better on heat output (X2 more so) then the Phenom II or the older hotcake 9xxx Phenoms (guessing most due to L3 cache)

  ... but for some purposes you have to look at an o'c system being more efficient, since CPU is only a fraction of total system power consumption and we are free to turn a system off when the tasks are completed.

  errr 65W

  If you are a supposed fan of silent computing, I'm surprised you aren't aware that you are better off buying a "standard" AMD CPU for much less and undervolting and underclocking to get even better results (ie. cooler and lower-power-consuming) than buying AMD's e-series (like MrSpadge describes).
