Hyper-Threading: Atom 230 Versus Celeron 220
Hyper-Threading
Giving the Atom processor Hyper-Threading technology was a smart decision on the part of Intel. The processor is much better utilized in threaded applications; it is able to increase its performance in our tests by up to 37%.

Here you can clearly see the slower in-order micro-architecture, which processes commands one after another. A Celeron at 1.20 GHz is 35% faster than an Atom at 1.60 GHz, but the Atom only consumes a fraction of the energy used by the Celeron. The AMD Sempron system, which uses almost the same energy in idle mode as the Atom system, is 43% faster.
