AMD Zen 6 CPU Core Instruction Set Architecture Unveiled: Featuring AVX512 FP16, VNNI INT8, and Additional Enhancements

The next-generation Zen 6 CPU instruction set architecture (ISA) from AMD has recently come to light through updates in the GCC compiler. This update marks a significant step forward in AMD’s CPU line, introducing new technologies that promise to enhance performance and efficiency.

AMD Zen 6 CPU Core to Incorporate AVX512, VNNI INT8, and More

A recent patch for the GCC Compiler, titled “Add AMD znver6 processor support, ”confirms the integration of AMD’s forthcoming Zen 6 core architecture. This patch emphasizes AMD’s continuous innovation by incorporating advanced features into its architecture.

AMD’s existing architectures already support AVX512, but the addition of AVX-512 FP16 in the Zen 6 design is expected to significantly enhance computational capabilities. Furthermore, the architecture will introduce capabilities for VNNI INT8, elevating performance in AI and machine learning applications.

In addition, notable insights from @InstLatX64 highlight a newly discovered Zen 6 CPU ID, B80F00, which likely corresponds to one of several Zen 6 families. The latest generation is anticipated to encompass server variants within the Venice lineup, available in Classic and Dense configurations. The Classic models will feature SP7 “B50F00″and SP8 “B90F00″SKUs, while the Dense models will include SP7 “BC0F00″and SP8 “BA0F00″SKUs.

The Classic version is expected to deliver up to 12 cores per core complex (CCX), while the Dense configuration promises a remarkable 32 cores per CCX. With the Venice family poised to reach an impressive 256 cores—distributed across 8 CCXs, and each CCX equipped with 128 MB of L3 cache—this architecture will support a total of up to 1024 MB of L3 cache.

Moreover, at least four client families will take advantage of the Zen 6 architecture. These include the high-performance AM5 “Olympic Ridge, ”featuring up to 24 cores and 48 threads (12 cores & 48 MB L3 per CCX), along with Gator Range, Medusa Point, and Medusa Halo. The multi-chip module (MCM) designs across these families will utilize the TSMC N2P process node, while the monolithic chips within Medusa Point and Gator Range APU lines are expected to adopt TSMC’s N3P/N3C nodes.

As AMD’s Financial Analyst Day approaches, excitement builds around potential announcements related to Zen 6 technology. While initial teases may emerge soon, concrete releases of Zen 6 CPUs are slated for next year, with a formal unveiling anticipated at CES 2026. Stay tuned for updates as AMD continues to push the envelope in CPU technology.
