yeah I know its not very fast... only about 2.0Ghz, but price is also quite low approx. $600. Also in my case, for helmer farm, if I do all 6 nodes with this chip, I will get about 100Ghz for almost half the energy use, right now with 6 quad core i7 I get about 80Ghz. I really like the 45W, even though its not fast, it is so easy to cool, might even consider passive cooling for silent renderfarm :)
The miracle part is, mini-itx with up to 128GB RAM!
