Zen 6

Zen 6 is the name for an upcoming CPU microarchitecture from AMD, shown on their roadmap in July 2024. It is the successor to Zen 5 and is believed to use TSMC's 3 nm and 2 nm processes. Desktop processors will be codenamed "Medusa", expected to be released under the Ryzen 10000 name, while Epyc server processors will be codenamed "Venice".
Zen 6 is expected to release in late 2026 to early 2027. It is expected that each Core Complex Die will contain up to 12 cores each. This would enable a maximum of 24 cores total for consumer platform chips.
The architecture is confirmed to introduce new instruction extensions, including AVX512_BMM, AVX_NE_CONVERT, AVX_IFMA, AVX_VNNI_INT8 and AVX512_FP16.

Zen 6c

Like with the previous two Zen generations, Zen 6 will come in a standard variant, as well as a high-core-density variant named Zen 6c. This will be used for server chips and likely also for mobile platforms.
