Everest: memory and arithmetic performance
Intel's Atom outperforms the VIA Nano in the SinJulia floating-point unit (FPU) test, which measures the speed of single-precision 32-bit FPU calculations. However, the Nano carries off the win on the double-precision 64-bit Mandel test, scoring 547 against the Atom's 143.
The differences are even more pronounced in the integer benchmarks. In the AES test, the Nano even outperforms the dual-core Pentium, and substantially so. In fact, with a score of 58,285, the Nano is faster than a Nehalem processor. VIA's Nano delivers outstanding floating-point performance thanks to an add algorithm and multiplier that both have exceptionally low latency. These features are aimed largely at accelerating high-definition video playback and 3D rendering.
The Nano comes out in front of the Atom in every other integer benchmark except for the Queen test. As far as memory performance is concerned, the Nano is clearly superior in every test.

To me it seems quite incorrect to classify the Atom 230 as one of the main netbook processors. Certainly the main netbook processor is currently the Atom N270, which is a rather different processor. For one, it does not support x86-64 instructions. It would be wise not to exptrapolate from the 230's results.
