This isn't the first time that Intel (or AMD, for that matter) has had problems with CPU counterfeiting, but it's an issue that largely faded from sight after Intel began clock-locking its chips. Apparently, such problems are still widespread in some areas; the People's Daily describes counterfeit CPUs that appear identical to real ones, including their packaging and seal of authenticity, while also describing the counterfeit efforts of computer manufacturers who buy older or used CPUs at cheaper prices and then clock them higher. It isn't 100% clear, however, if these are two mostly separate counterfeit campaigns, or if they're directly linked.
Intel will undoubtedly come down hard and fast on any manufacturer it catches selling counterfeit CPUs. The burgeoning Chinese market is simply too important a growth area to risk. Initial reputations, once forged, are extremely difficult to change, as we've seen repeatedly in the Intel vs. AMD war that's played out in the U.S. Cracking down on counterfeiters or scheming manufacturers could lead to higher system pricing, which might hurt Intel adoption in the short run—but in the longer term, it's the only way to go.
