FUD Zilla reports NVIDIA is going to start marketing ION for Core 2 and CULV platforms as well:
ION launched as a brand reserved exclusively for Atom based platforms including netbooks and nettops and now Nvidia is fine if you use ION for Core 2, CULV or other non-Atom based CPUs. Since the brand is successful, ION in the name might help companies to sell more products.
Nvidia gave companies a green light to use ION for non-Atom products and Nvidia's top brass has confirmed that “MCP79, ION and Geforce 9400M are the same thing” and the customer can decide which of the three names it wants to use. Since the first name is actually a codename customers usually go for ION or Geforce 9400M.
