The AMD Zen5 architecture of the Ryzen 9000 series retains the AM5 socket, ensuring compatibility with existing 600 series motherboards. However, a new generation of 800 series motherboards will also be introduced, launching approximately two months after the processor release.

According to recent reports, the Ryzen 9000 series is scheduled for an official release on July 31st, while the X870E and X870 motherboards will be available by September 30th. This two-month delay allows for the current X670E, X670, B650E, and B650 motherboards to receive BIOS updates to support the new processors.

The delay in the release schedule is likely intended to give motherboard manufacturers ample time to prepare the new products and to enable the old motherboards to reduce prices and clear out inventory.

Interestingly, the Ryzen 9000X3D series is also speculated to be released around the end of September, but this is not yet certain.

The 800 series motherboards will continue the hardware trends of the 600 series (codenamed Promontory 21), with several specification improvements. Notable changes include standard USB4 ports, standard PCIe 5.0 x16 graphics slots, support for higher EXPO DDR5 memory frequencies, and new designs by manufacturers.

The X870E maintains a dual-chip design, with key differences from the X670E being the addition of USB4 interfaces and higher EXPO frequencies. The graphics card continues to support PCIe 5.0 (although it hasn't been utilized yet), SSDs support PCIe 5.0, and expansions include 12 PCIe 4.0 and 8 PCIe 3.0 slots.

The X870 has undergone significant changes, transitioning from the X670's dual-chip to a single-chip design, resulting in reduced PCIe expansion capabilities to 8 PCIe 4.0 and 4 PCIe 3.0 slots, likely making it more affordable.

Following these will be the mainstream B850 and B840 motherboards. The B850 is comparable to the current B650, with the primary difference being the upgrade of the graphics card slot to PCIe 5.0, optionally retaining USB4 support, and maintaining the same number of PCIe expansions. It also supports processor and memory overclocking.

The B840 is unique, utilizing the new lite chip Promontory 19, which does not support processor overclocking (but can overclock memory), and features PCIe 4.0 for graphics cards and SSDs, lacks USB4 support, and offers only 8 PCIe 3.0 expansions.

At the entry level, the A620 and A620A motherboards will continue to be used without any new introductions.
