AMD is in no hurry to reveal its plans to expand the range of Ryzen CPUs, limiting itself to statements of intentions to release Zen 5 chips in the second half of this year. Meanwhile, new details continue to arrive from unofficial sources. For example, it is claimed that Granite Ridge desktop processors will form the Ryzen 9000 line, and along with them, AMD will release 800 series chipsets.
The top chipset for the updated AM5 platform will be the X870E. In fact, this is a set of three chips, since AMD wants to oblige motherboard manufacturers to add support for the USB4 interface. Like the current X670E, the logic set will consist of two “twin hubs”, but now they will be joined by a separate chip responsible for USB4. It is planned to use the ASMedia ASM4242 controller, but alternatives will probably appear in the future.
If we talk about the Ryzen 9000 (Granite Ridge) processors themselves, they will continue to use a chiplet layout: one/two 4-nm crystals with Zen 5 cores and a 6-nm I/O chip. The RAM standard is DDR5-6400, but AMD is also talking about support for faster EXPO profiles, for example, DDR5-8000.
Please note that Granite Ridge processors will also be compatible with previously released AM5 boards based on 600-series chipsets (subject to a UEFI firmware update). AMD previously promised to support this platform until at least 2025.
