AMD's Energy Efficient and EE SFF CPUs

I'm working on a quick article on AMD's Energy Efficient and Energy Efficient Small Form Factor CPUs and I'd like a bit of feedback from you all. Currently I'm going to be looking at overclocking, power consumption and temperature in comparison to the non-EE parts, but is there anything else you'd like to know about these new CPUs? Performance is unchanged, so there's not much else to look at/talk about. Let me know.
Take care.

It would, but how much is what matters. I am quite against overclocking X2s over 2.8GHz because their power draw can rise dramatically (in the 100W+ range) but below that I'm quite happy doing so, even in my "silent" systems. Conroes look like the barely hit ~70W at 2.93GHz but what about, let us say, 3.5GHz?njkennedy - Friday, July 21, 2006 - link
I'll throw in another vote for cpu power draw. I'll be running a pc 24/7 so every watt less is 8760 watt/hrs per year I save. That may be peanuts, but it's another bennie on top of less heat (and less work for my AC).soydios - Friday, July 21, 2006 - link
performance per watt compared to Turion, regular AMD64, Yonah, and Conroeunderclocking enough to possibly have passive cooling (that would be an ace up AMD's sleeve for HTPCs)

What are they made of? Is AMD dipping there toe into SiGe at 90nm so they can get it right at 65nm? Hmmmm.Operandi - Thursday, July 20, 2006 - link
It seems like Anandtech has been slowing moving to an "overclockers" site, something I'm not at all interested in. The Core2 guide particularly read that way to me.I'd like to see numbers on heat and how that that relates to building a low noise machine. Less heat = lower fan RPMs which should = less noise. I'm not sure if you're setup for those kinds of tests (sound measurements) but a Core2 vs. the new EE Athlons article could be interesting.

I agree about Anandtech gradually becoming an overclocker's website. The articles also tend to be more and more focused on $200 motherboards, $500 GPUs. I enjoy reading hardware related articles that are relevant to the rest of us who dont spend that kind of money and this new trend of heavy emphasis on overclocking and on high priced hardware is getting a little annoying to me. Enthusiasm for hardware <> Overclocking ! I've been reading this site for several years now and I'd hate to have to go certain other ad-infested hardware sites to get my hardware fix.Furen - Thursday, July 20, 2006 - link
Heat is related more to power draw than temperature, since different cooling methods will yield different temperature readings. A CPU power chart (isolated from system power) would be nice, too, in my opinion.Operandi - Thursday, July 20, 2006 - link
Temperature is a result of thermal output. Lower thermal output = lower temperature, which = less noise.From my perspective the lower energy needs for these chips have one practical application, and that’s lower noise.

Yes, temperature is a result of thermal output but my point was that cooling efficiency affects this dramatically. For example, I have a watercooling system that gets both a Cedar Mill and an X2 down to similar temperatures but this does not mean that both produce the same heat, it just means that the cooling is good enough for both. If you look at power draw, on the other hand, my X2 has a 30W+ advantage, which is probably a decent enough match to the heat production difference between the two chips.Mysoggy - Thursday, July 20, 2006 - link
Since a lot of people will be running these in SFF and Laptops with C&Q enabled, I would like to see benchmarks with it enabled vs disabled. I think it will go a ways in helping to determine whether people actually decide to use this feature.
