Zen 6 ("Morpheus") [1] is the name for an upcoming CPU microarchitecture from AMD, shown on their roadmap in July 2024. [ 2 ] [ 3 ] It is the successor to Zen 5 ( "Nirvana" ) and is believed to use TSMC 's 3 nm and 2 nm processes.
Lastly, keep in mind that AMD is also developing a successor GPU to the MI300 called the MI325X -- slated to launch in 2025. Moreover, the company's MI400 architecture is targeting a launch date ...
The decision to move to a chiplet-based GPU microarchitecture was led by AMD Senior Vice President Sam Naffziger who had also lead the chiplet initiative with Ryzen and Epyc. [6] The development of RDNA 3's chiplet architecture began towards the end of 2017 with Naffziger leading the AMD graphics team in the effort. [7]
Zen 5 was designed with both 4nm and 3nm processes in mind. This acted as an insurance policy for AMD in the event that TSMC's mass production of its N3 nodes were to face delays, significant wafer defect issues or capacity issues.
As of July 2017, the Graphics Core Next instruction set has seen five iterations. The differences between the first four generations are rather minimal, but the fifth-generation GCN architecture features heavily modified stream processors to improve performance and support the simultaneous processing of two lower-precision numbers in place of a single higher-precision number.
Zen 4 is the first AMD microarchitecture to support AVX-512 instruction set extension. Most 512-bit vector instructions are split in two and executed by the 256-bit SIMD execution units internally. The two halves execute in parallel on a pair of execution units and are still tracked as a single micro-OP (except for stores), which means the ...

CDNA (Compute DNA) is a compute-centered graphics processing unit (GPU) microarchitecture designed by AMD for datacenters. Mostly used in the AMD Instinct line of data center graphics cards, CDNA is a successor to the Graphics Core Next (GCN) microarchitecture; the other successor being RDNA (Radeon DNA), a consumer graphics focused microarchitecture.
