error in 'microcode revision guidance' Feb 20 2018

[CMurp6]

I'm seeing an apparent mismatch between Public Name and CPUID on page 4.

Intel® Atom® x5-Zxxxx CPU is listed as having CPUID 406C3

Intel® Pentium® Processor N3xxx is listed as having CPUID 406C4

However I have a Pentium N3700 which reports CPUID as 406C3, following excerpts from the listed command.

Hello, cmurf.

Thank you very much for contacting the Intel® Communities Team.I understand you would like to know why the CPUID of your processor is different when running Todd Allen's Tools: cpuid from the one the Microcode Update guidance shows. I will be more than glad to assist you further.Please bear in mind that this tool you are using is a 3rd party software and the results might not be so accurate. Please run thehttps://downloadcenter.intel.com/download/7838/Intel-Processor-Identification-Utility-Windows-Version?product=5982 Intel® Processor Identification Utility and the https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool Intel® Processor Diagnostic Tool and verify your CPUID with these tools.Then, I would like to know if you are facing any type of issue with your NUC and you were forced to look for this information?Antony S.

Dear Antony :

I also found this issue. My process is Z8350 and Z8550, but I got the CPUID is 406C4.

I was use the Intel Proocessor Identification Utility to check it. Can you help to check it, Thanks.

Could be the document is being updated, or the site is undergoing maintenance.

Give it some time.

Hello, Aking.

Allow me to inform you that this CPUID is a general one for this processors families. Please bear in mind that the microcode update will be released by either a firmware update from your system manufacturer or your OS. Please double check if there is an update for your machine with them.Antony S.
