I notice that SKD044 on page 28 this PDF:

explains why the discrepancy occurs and how large it is likely to be for this chip.

I appreciate the link, but I'm unable to find the portion that you refer to. Could you point more exactly to the details you found?

SKD044 doesn't exist in that document, SKL044 is about WRMSR, and nothing on page 28 seems relevant. I did find SKD044 in a different document (http://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/6th-gen-core-u-y-spec-update.pdf) but still about WRMSR. The closest erratum I did find was SKL048 "Processor May Run Intel AVX Code Much Slower than Expected", but this is only when coming out of C6, and doesn't give other details.
