Fusion chips are better than Atom equivalent (at least on a per clock ratio base). Atom's often don't offer 64-bit support, and don't have out of order execution. In practical benchmarks, an AMD Fusion clocked at 1GHz will perform similar to a 1.6GHz Atom.
They do seem to use a bit more power than an Atom in my experience, but overal I'm very satisfied with Fusion hardware for low-power devices. I own two, a netbook and a tablet, both work fine and are very snappy for their price, age and specs. A friend of mine owns a full-size laptop with Fusion hardware and she reports an excellent Linux experience as well.
