AMD's next-gen Zen 6 CPU ISA has been revealed in the latest support added to the GCC compiler, alongside the initial family.
AMD Zen 6 CPU Core To Support AVX512, VNNI INT8 & More According To Latest GCC Compiler Support Update
The GCC Compiler has received a new patch titled "Add AMD znver6 processor support," which essentially adds support for AMD's next-gen Zen 6 core architecture.
The patch also reveals initial ISA (Instruction Set Architecture) for the Zen 6 core, which includes:
- AVX512_FP16
- AVX_NE_CONVERT
- AVX_IFMA
- AVX_VNNI_INT8

While AMD already offers AVX512 support on existing Zen architectures, AVX-512 FP16 will further boost the capabilities of future Zen architectures. The architecture will also support VNNI INT8 as part of its new ISA.
In another post, @InstLatX64 has also discovered a new Zen 6 CPU ID, B80F00, which should point toward one of the several Zen 6 families. Currently, Zen 6 is expected to feature the server Venice lineups in two variants, Classic & Dense. The Venice Classic chips have the SP7 "B50F00" SKUs, and the SP8 "B90F00" SKUs. The Venice dense chips have the SP7 "BC0F00" SKUs, and the SP8 "BA0F00" SKUs.
The classic line will feature up to 12 cores per CCX, while the dense line will feature 32 cores per CCX. We know that the Venice lineup will max out at 256 cores, so that's 8 CCXs, and each CCX carries 128 MB on the dense line, so we will get up to 1024 MB of L3 cache.
Besides that, there are at least four client families that will feature the Zen 6 core architecture. These include the high-end AM5 "Olympic Ridge" with up to 24 cores and 48 threads (12 cores & 48 MB L3 per CCX), Gator Range, Medusa Point, and Medusa Halo. All families with an MCM design will leverage the TSMC N2P process node, while monolithic offerings within the Medusa Point and Gator Range APU lines are expected to utilize TSMC N3P/N3C nodes.
AMD's Financial Analyst Day is just a few days away, and while we can expect a few Zen 6 teases, the actual announcements for Zen 6 CPUs are expected to take place next year, starting CES 2026, so stay tuned.
