Sources said that in addition to the 2025 EPYC Coaster processor, which will use a 3nm process,All of AMD's other upcoming Zen 5 architecture processors will be built using Taiwan Semiconductor's 4nm processAMD is likely to skip 3nm and go straight to 2nm in Zen 6.
TSMC will be working to improve its 3nm node throughout 2024, but in addition to big customer Apple, other customers including AMD, Mediatek, Nvidia and Qualcomm are now considering delaying or even skipping the 3nm process altogether.
High production prices could force AMD to skip at least the 3nm generation for consumer processors, the sources said. AMD's detailed roadmap for the next two years, posted online,Notebook and desktop processors will stick with 4nm nodes, while NVIDIA may move to 3nm by 2025.
The only AMD processor with a 3nm process is likely to be the server-grade EPYC chip due out in 2025.
In the desktop processor space, the current Zen 4 Ryzen 7000 series is expected to be replaced by the Granite Ridge Zen 5 with a 4nm core and 6nm interconnect in 2024.
The Zen 5 is understood to be an important generational leap forward for AMD consumer processors,It will be based on a new, more efficient architecture, a re-streamlined front end, and integrated AI optimization.
Next year, AMD plans to use a "Hawk Point" generation of updated Phoenix mobile processors still based on the 4 nm Zen 4. Code-named "Krackan Point", Generation 025 will bring the Zen 5 into AMD's mid-range mobile APUs, but these will still be manufactured with the 4nm process. In addition, in 2025 AMD will launch the Escher 4nm line of entry-level notebooks, similar to the Mendocino.
On the desktop, AMD will launch the Ryzen 8000 Granite Ridge CPU in 2024, based on the Zen 5 architecture, but it is unclear which TSMC process it will use, The Ryzen 7000 Series mobile APUs will integrate the Zen 4 CPU core with the RDNA 3 GPU.
