Ultimately, Intel created the HEDT market. I could make a case for the original HEDT CPU debut being in late 1995 with the introduction of the Pentium Pro. It was a socket 8 processor, instead of the more common socket 7 or super 7 socket used by Pentium and later Pentium MMX CPU’s at the time. Its motherboards had a more server or workstation-oriented design philosophy. It was used by professionals and prosumers back in the day for many of the same reasons that modern HEDT systems are used today. For many, many years, Intel has been the master of this domain. This is arguably easy when you are the only one playing the game. It was a market that no other company even had products for.
