The motherboards are all in ATX format; however, mATX/ITX models should follow later this year. They all support DDR5-5600 MT/s memory speeds natively, with some models supporting over 8000 MT/s memory speeds. In terms of chipset, the X870E series uses two Promontory 21 dies with support for USB 4 and Gen 5 GPU/SSD (24x Gen 5 CPU Lanes, 8x Gen 4 + 12x Gen 3 PCH Lanes). The X870 will use just one of the dies, retaining the Gen 5 lanes, however the PCH Lanes will be limited to 4x Gen 4 + 8x Gen 3.
