Zen 3 is the codename for a CPU microarchitecture by AMD, slated for release in late 2020.[1] The successor to Zen 2 is expected to be fabricated on an improved[3] 7nm MOSFET node from TSMC (initially referred to by AMD as 7nm+) and powering Ryzen mainstream desktop processors (codenamed "Vermeer") and Epyc server processors (codenamed "Milan").[4][2] Zen 3 is expected to be the last microarchitecture before AMD switches to DDR5 memory and new sockets.[1] Zen 3 will be supported on motherboards with the 500 series chipsets. 400 series boards will also see support as AMD will share code allowing motherboard manufacturers to support Zen 3 on select B450 / X470 motherboards using select beta BIOSes.[5]
Technology node
From AMD's materials which stated "7nm+" it was initially assumed by the media that the 7nm process would be the new EUV (extreme ultraviolet) lithography from TSMC (N7+). A shift to N7+ would be expected to lower power consumption by 10% and offer up to a 20% increase in transistor density. This would also allow for higher clock speeds at the same power consumption.[4] AMD has clarified that they did not mean any specific process by "7nm+" and that they would be using an improved version of 7nm (N7), which includes the possibility of the DUV (deep ultraviolet) N7P process, or some other unnamed process.[3]
Epyc microprocessors
The Epyc server line of chips based on Zen 3 is to be named Milan and will be the final generation of chips using the SP3 socket.[2]
