This of course raises the question, "What's a Ryzen Pro?" > The business answer: Ryzen Pro 3000 is a line of CPUs specifically intended to power business-class desktop machines. The Pro line ranges from the humble dual-core Athlon Pro 300GE all the way through to Ryzen 9 Pro 3900, a 12-core/24-thread monster. The new parts will not be available for end-user retail purchase and are only available to OEMs seeking to build systems around them.
