Unofficial AMD X570 platform diagram surfaces online, as well as images of MSI X570-based mainboards

Those planning for a platform upgrade in the coming weeks might want to wait for the first X570-based motherboards to come out. This chipset will introduce PCIe 4.0 to consumer desktop computers and since the images of two MSI mainboards that use it also surfaced online, moving up to a Ryzen/EPYC-powered desktop computer with an X570 motherboard should be possible in a few weeks.

PCIe 4.0 is now only available in datacenter GPUs such as the Radeon Instinct MI60, but the mainboards and processors to go with them are both coming: 

• The two MSI motherboards based on the X570 chipset belong to the mid-range MPG series and feature an onboard fan and dual PCIe x16 slots, most likely PCIe 4.0 ones. The names of these boards are X570 Gaming Plus and X570 Gaming Pro Carbon.
• The processors that will launch with PCIe 4.0 support and will be perfect matches for the X570 motherboards are currently codenamed Rome (EPYC) and Matisse (Ryzen).

The leaked diagram below confirms the presence of 24 PCIe 4.0 lanes, with four of them dedicated to 32 Gb/s M.2, and four used as a 16 GT/s bus between the processor and chipset. The Realtek ALC1220 and NV6795 Super I/O controllers are connected directly to the processor.

The good news is that X470 motherboards might be able to work at PCIe 4.0 bandwidth when used with upcoming Matisse (Ryzen 3000) processors. For now, all these should be taken with a grain of salt, but it won't take long for the AMD X570-based solutions to hit the market.

As usual, feel free to share your thoughts with the rest of us in the comments section below. Would you go for a PCIe 4.0 motherboard this summer or not? Are you eagerly waiting for the new AMD processors or you happen to be still a faithful Intel follower?
