Intel has made the move of adopting the sequential naming scheme it used for its famous Pentium brand, with reference to its new Core line of chips. Therefore, the company will unveil Core 2 Duo processors - desktop chips based on the Conroe chip.

Each Core 2 Duo chip will also have a model number that will indicate how much power it consumes and its relative performance, said Intel spokesman Bill Kircos. The Conroe processors will fall into either the 4000 series or 6000 series, while Merom processors will use either the 5000 series or 7000 series numbers, he said.
