In July AMD released its Ryzen 3000 Series to critical success on all fronts.  The series was bookended by the Ryzen 5 3600 six core and twelve threaded budget-friendly  CPU and the monstrous Ryzen 9 3900X, a twelve core and twenty-four threaded powerhouse.  The later has proven to be a bit of a slippery fish to get a hold of and the Ryzen 9 3950X, the flagship sixteen core and thirty-two thread version, has been pushed back to October. But over the past few weeks, there have been two other Ryzen 3000 Series CPUs making headlines, the Ryzen 9 3900 and the Ryzen 5 3500X. Today AMD has officially announced the Ryzen 9 3900 and the Ryzen 5 3500X, but there's a bit of a catch to both.
