As rule of thumb: Atom CPUs processing power is

depends on the model. I suppose the only way to tell is to try..
I don't have any benchmarks handy to back myself up, but everything I've
read about Atom CPUs tells me that they're substantially slower than any
of the Core series CPUs. Atom uses a very simple, in-order design that
sacrifices performance for power-efficiency -- I definitely wouldn't
recommend one for any application where you suspect CPU power might be a
concern.
FWIW, I've found that the dual-core 1.7Ghz Core i5 in my laptop beats
the older dual-core 3Ghz Core 2 Duo in my desktop by about 15-25%,
particularly in multi-threaded applications (compiling Ardour 3, in this
case). I'd bet that even that old Core 2 Duo is easily twice as fast per
Ghz as an Atom. These modern Core chips are *fast*!
