Ahead of the rumored late-October debut of Intel's 12th Gen Core "Alder Lake" processors, motherboard makers started teasing their compatible Socket LGA 1700 products. Older reports suggest that in 2021, Intel will only release unlocked "K" and "KF" SKUs, and motherboard partners will only launch boards based on the top Intel Z690 chipset. The lineup is expected to be joined by more affordable non-K SKUs in Q1-2022, along with lower chipset models such as the B660 and H670.

The MEG Z690 ACE appears to introduce a new design scheme with die-cast metal mesh rear I/O shrouds, and a gold+black trim. The I/O shroud design is interesting as it lets the VRM heatsink underneath breathe better. The silver-white MPG motherboard is possibly the MPG Z690 Force. MSI is probably trying to get this to rival the ROG Strix-A SKU by ASUS. The third teaser, of a brushed gunmetal shroud, is likely the MAG Z690 Tomahawk. Like most other brands, MSI appears to have an extensive lineup of Socket LGA 1700 motherboards with DDR4 memory slots, although boards with DDR4 are restricted to the MAG and entry-level PRO series. The mid-tier MPG and enthusiast-segment MEG series boards only come with DDR5.
