Intel Core i3-350M already making a stepping change
 

Released just three month ago, Intel's 32nm Core i3-350M is scheduled to move from the current C2 stepping to K0 in Q2. The 2.26 GHz mobile processor will be getting new S-spec and Material Master numbers, as well as a new CPUID (0x20655h) due to the move, and will require a BIOS update in order to be properly detected.
