"Oracle will continue to recognize each core as a separate processor; however, the processor definition has been amended as it relates to counting multi-core chips to determine the total number of processor licenses required. For the purposes of counting the number of processors that require licensing, the number of cores in a multi-core chip now shall be multiplied by a factor of .75. Previously, each core was counted as a full processor."

I think this is rubbish! A processor is a processor no matter how many cores it’s got! Sorry Oracle this just smacks of trying to make extra cash!
