Functional Comparison Of The Atom

Atom Benchmarked: 4W Of Performance
By

We compared the Atom processors with the dual-core Pentium and Celeron 220 on the embedded board D201GLY2. The mini ITX board is the direct technical predecessor to the Atom desktop solution.

The ECS 945GCT-D board used in our tests of course contains an Atom 230 running at 1.60 GHz.
