Xbitlabs.com says 35W "Athlon SFF processors on Palomino and Thoroughbred cores are in the AMD Ordering Part Number table for May. It means that Athlon SFF should also be announced very soon. Athlon SFF (Small Form Factor) is a new AMS solution designed for quiet fanless PCs. As we see, from the table, these CPUs will feature lower Vcore and will be rated up to 2000+. Athlon SFF is expected to work in a special processor socket different from the current Socket A."
Fanless at 35W seems like quite a challenge, but this is interesting news for PC silencers.
