But my impression could be wrong. The thermal requirements of standard Opteron and Athlon64 are the same. There are low-power Opterons (30W & 55W), which aren't available in the Athlon64 line. > It's also interesting to note that there are now plenty of > Athlon64-based notebooks, but I haven't seen any Opteron > notebook so far, WHY would you want an Opteron notebook? You certainly don't have the room in a notebook to add all kind of I/O devices to utilize the 3 HyperTransport links (vs. the 1 of Athlon64). I don't know of anyone that wants to track down registered(buffered) SODIMM's either. I don't think most notebook design houses could do a proper 2P notebook design. Thus what is the advantage of Opteron over Athlon64 in the notebook arena? > which lead me to believe that the Athlon64 > has some power-saving features which the Opteron lacks. > Does the Opteron have "PowerNow" or "Cool'n'Quiet"? Yes, Opteron definitely has "PowerNow!". You need a rev.CG processor and BIOS that supports it. -- -- David (obrien@FreeBSD.org)
