AMD plans to introduce its Ryzen 8000 desktop CPUs, also known as “Granite Ridge,” sometime in 2019. The most recent batch of Team Red product roadmaps indicate that the Zen 5 core microarchitecture will be released alongside (Navi) RDNA 3.5 iGPU cores. We already know that Granite Ridge will be available in a Socket AM5 package, but today’s leak suggests that these next-generation chips are planned to use the same IO die as sported by AMD’s current Zen 4 desktop family. This information comes from hardware tipsters Olrak29_ and Kepler_L2, who have made claims on social media.
According to these recent speculations, the “reused” Ryzen 7000 IOD (I/O Die) chiplet will include the standard 28 PCIe Gen 5 lanes, memory controllers, USB capabilities, and RDNA 2 iGPU cores. Intriguingly, AMD advertises the Ryzen 7000 “desktop” CPUs with Navi 3.0 capability, yet the Radeon 710M iGPU is really built on the RDNA 2 graphics core, as Wccftech notes. The newest RDNA 3.5 GPU core, which will be available in the Strix APU family next year, was described as being supported by the next-gen lineup, however that is also untrue. According to the publication, the 6 nm Rembrandt (6000G) and 4 nm Phoenix (7000G) desktop Ryzen APUs could introduce “RDNA 3.5 GPU cores on the AM5 platform”.
