AMD’s highly anticipated Ryzen 9000 processors may launch in August, a couple of months following the (expected) Computex announcement. The tidbit comes from an AOOSTAR employee who claims that the Zen 5 CPUs will be launched in August. AOOSTAR is a mini-PC manufacturer with several NUC-like designs based on the Ryzen 6000 “Rembrandt,” Ryzen 7000 “Phoenix,” and Ryzen 8000 “Hawk Point” processors.
Update: The latest rumor from the Chiphell forums claims that the Ryzenb 9000 processors for desktops and DIYers will launch in July. Like previous generations, four SKUs are planned, including the Ryzen 5 9600X, Ryzen 7 9700X, Ryzen 9 9900X, and the 9950X. These chips will feature 6, 8, 12, and 16 cores, respectively, and twice as many threads.
As you can see, the core counts are unchanged, and much of the R&D focus has gone into improving single-core performance and IPC. You can read all about the Zen 5 core architecture, and the rumored specifications of Granite Ridge, Strix Point, and Strix Halo here.
Board partners have already released firmware updates adding support for the Ryzen 9000 CPUs across various A620, B650, B650E, X670, and X670E motherboards. AMD is expected to launch the new 800-series chipset in the coming months, but for those with a 600-series board, there’s not much need for an upgrade.
The source claims that their first Ryzen-based mini-PCs will be available in October. However, since AOOSTAR only uses mobile SoCs, this means that Strix Point (Ryzen AI 300) may launch in August, right after or alongside the Ryzen 9000 “Granite Ridge” desktop lineup.
In related news, AMD has sent out a Linux kernel patch that initializes support for hybrid-core processors (heterogenous topologies) on the latest CPU frequency drivers for Ryzen CPUs and APUs. Unlike Intel’s P and E-cores which use different ISAs, the Zen 5 and Zen 5c cores feature the same instruction support, including AVX512.
