AMD has consistently swatted away rumors that its Zen 3 chips are delayed [tomshardware.com] and has clarified that its chips wouldn't use TSMC's 5nm process [tomshardware.com]. AMD has long maintained that it's Zen 3 chips would come to market this year, which makes sense given the Zen 3 EPYC Milan data center chips on the roadmap. The company later clarified that Zen 3 "client" chips would also come to market this year [tomshardware.com]. That's an important distinction, with the term "client" signifying that we'll see chips for regular consumers this year, too.
