Gigabyte Z690 AORUS, AERO, Gaming, and UD series have been leaked
We now have as many as twelve AORUS Z690 series including Xtreme, Master, Ultra, Pro, and Elite designs, along with content-creator AERO and mid-range Gaming X series. More importantly, we can now also share two next-gen MSI UNIFY and UNIFY-X motherboards, both looking almost identical except for the memory support: the UNIFY-X is dual-DIMM only.
Gigabyte is also set to launch Micro-ATX and Mini-ITX AORUS ELITE series and the overclocking board called Tachyon. The XTREME variant is also getting a liquid-cooling treatment under the WaterForce series, unfortunately, we do not have pictures of these boards yet.
