In yet another slide that got leaked we see something interesting from the AMD front. Matisse basically is what is to be AMD's Ryzen 3, which will be based on Zen 2 cores. The chipset for it is called X570, and would see PCIe 4.0 support.
The leaked slide from gamer.com.tw is a little peculiar in the sense that seems slightly dated with B450 chipset and Athlon 200GE highlighted. They do look valid enough though.
X570 would launch at Computex 2019, which runs from 28 May to 1 June 2019. So from here onwards we can assume Ryzen 3000 based on Zen2 cores would at least be announced in roughly half a year time. Good times.
