How Is Breaking The 4 GHz Barrier Possible? Continued
To prevent resellers from scamming buyers by substituting counterfeit or modified parts, Intel packages the CPU so that its designator is visible through a clear plastic window. This enables buyers to verify that the specification number printed on the box agrees with the number on the part itself, without requiring them to open the package. This means you can check the authenticity of the CPU without even having to buy the processor first.
A clear plastic window lets buyers ascertain that the specification number on the box agrees with the number printed on the CPU.
Of course, those who buy their CPUs online can't perform such checks in advance of purchase, but that's where refund policies come into play: most buyers can return a CPU purchase within some days for a full refund without having to provide a reason. Here's an overview of all Pentium processors for Socket 775, with their code names and version numbers.
