https://videocardz.com/80714/msi-mpg-x570-series-leaked-gaming-pro-carbon-gaming-plus The leaked Gaming Plus is the lower-tier of the two leaked solutions of today, cutting on reinforcements on some expansion ports (such as the PCIe 16x slot). The Gaming Pro Carbon features a fancier design (with RGB lighting); the chipset hroud also serves as cooling for M.2 slots you can populate underneath (or so it seems). The Gaming Pro Carbon has more attention to detail on the placement of connectors such as SATA, and seems to have a slight advantage on the overall motherboard power delivery circuits, but these are just being eyeballed. One thing we can see is that while the Gaming Pro Carbon features MSI's Audio Boost feature, the Gaming Plus doesn't. Expect more details to be available closer to launch. That should be soon after the AMD keynote at Computex 2019.
