     With so many different processors on the market today it's sometimes hard to keep them all straight.  Things are not helped by the frequently misleading naming conventions given by both AMD and Intel.  To help clear up the actual specifications we have compiled the following chart.

     As with all projects of this mammoth size, we have done our best to cover as many of the processor models currently used in desktop builds.  If you see something incorrect or missing that you might like us to add, please feel free to drop us a note.  Until the next revision, consider this a helpful snapshot of the CPU market Q4 2006!
