Hyper-Threading: Atom 230 Versus Celeron 220

Atom Benchmarked: 4W Of Performance
By

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%.

Speed: Atom 230 versus Celeron 220 versus Sempron 64 LE-1100

Atom 230 – 1.60 GHz
Benchmark Celeron 220 1.20 GHz Sempron 64 LE-1100 1.90 GHz
iTunes 36.9% 57.5%
Lame 51.5% 61.1%

Total: 35.2% 43.7%

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.
