Major AMD partners like ASUS, ASRock, GIGABYTE, and MSI have unveiled their latest AMD AM5 motherboards featuring the X870E and X870 chipsets. The new motherboards offer broad compatibility, supporting not only the latest AMD Ryzen 9000 series, but also the Ryzen 8000 and 7000 CPUs. These boards are aimed at high-end and enthusiast users, sporting optimized VRM designs and enhanced I/O capabilities, including WiFi 7 and USB 4 support.
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.
