We can therefore expect the PowerVR to manage 25 Mh/S at .9w. This gives us a Mh/J of 27.7, compared to 1.8 for a 5850.
This has potential.
Color me impressed, I don't believe it will either give out that hash power or use that little power. How could they provide a chip that is more than ten times for efficient than high-end desktop versions, for a device needing less complexity than a desktop PC.
