VIA Nano ultra-low power processor
POV-Ray is a pure test of CPU rendering power and it shows that the 1.8GHz Nano has significantly better performance than Atom. The VIA chip completed the test in 19 minutes; the Atom took 27 minutes.

The problem is that the Nano system draws more power than Atom – 80W against 60W – which rather blows a hole in VIA’s argument that it has a 47 per cent greater fuel efficiency than the Intel offering. That figure is achieved by averaging work loads and power draws, but we very much doubt that mobile systems with the same battery would yield a significantly longer runtime with the Nano.
