cpuid: distinguishing between new processors with same family/model/stepping

[todd_allen]

There are versions of the following two processors with the same family/model/stepping (0F48):
Dual-Core Xeon Processor (Paxville A0)
Dual-Core Xeon Processor 7000 (Paxville A0)
There are lots of similar situations in older chips. Typically, I use the brand string to disambiguate. But I don't have examples of both chips. Could anyone who has access to them please indicate what the brand strings are for those two chips?

And while I'm at it, I have the same question for these 3 chips (with f/m/s of 0F62):
Pentium 4 Processor 6x1 (Presler B1)
Pentium Processor Extreme Edition 955 (Presler B1)
Pentium D Processor 900 (Presler B1)

Thanks for any help.

Careful -- Intel Customer Support's processor site points out:

A processor's family, model and stepping numbers refer to the manufacturing process on which a processor was manufactured and can be useful in identifying a processor in a system. The family, model and stepping numbers do not directly translate to a specific processor, and should not be used as a tool to identify a specific processor.

Processoridentification utilitieshave been developed by Intel Corporation to identify the processor inside a system, assuring the processor contains intended technologies andis operating at the tested and rated frequency intended by Intel Corporation. Beginning with the Pentium III processor, theidentification utilities have the capability to provide actual and intended frequency, or speed, information.

Software developers using CPUID for processor identification should continue torefer to AP-485.
