Years ago, Intel revised manufacturing policies and began hard locking multipliers on all their processors, supposedly to reduce or eliminating “rebadging” of their processors, which was basically selling a processor as a higher speed than it really was. For the most part, that's been done away with and isn't heard of much. However, Pentium Ms in China
are showing up that have been relabeled, and are being sold. It seems the total amount came from a shipment that was intended to be sample processors, not intended for retail sale. Intel has said that the problem is small, and has sent a “reminder” to their suppliers that samples are “not for sale”. Rebadging in and of itself is a fraudulent practice, and can cause a lot of headache for the victims, though thankfully it has become very rare in the CPU world these days.
