In Raptor Lake's case a very common pattern that me and others have noticed is that sometimes the wrong 8-bit value is delivered. This happens when reading 8-bit registers such as AH or AL, which are just slices of larger integer registers, and don't have dedicated physical storage. The operation that pulls out the higher or lower 8 bits of the last 16 bits of a regular register is usually done via a multiplexer or MUX. 25/31
