AMD has introduced two new mainstream desktop processors in the Zen 2 lineup — the Ryzen 3 3100 and the Ryzen 3 3300X alongside the new B550 mid-range chipset. These CPUs are 4C/8T 65W parts and help fill the void in the US$100 to US$150 range. However, they face competition from AMD's own Ryzen 5 1600 AF and upcoming Renoir Ryzen 4000 desktop CPUs.
