Fyi, there are three types of CPUs
Engineering sample: testing different variables of the silicon, no product SKU in CPU-Z (like Gulftown A0)
Qualification sample: testing the final version of the silicon, carries product SKU in CPU-Z (like all media samples)
Retail sample: -duh-
I assume all the question mark Q-SPEC QDxx have "genuine intel" as product name in CPU-Z?
As a sidenote to this, I would like to advocate for allowing qualification samples to be used in all rankings. So, as long as there is a product SKU identifiable in CPUZ the processor sample is allowed in any HWBOT ranking. Anything that just carries the genuine intel naming scheme remains for the pros.
