AMD splits Zen 7 into three EPYC families for 2028 and starts selling server CPUs by the agent — Florence, Ferrara, and Fidenza to be applied across AI-focused product stack

AMD used its recent Advancing AI 2026 event in San Francisco to launch sixth-gen EPYC "Venice" processors, Instinct MI400 Series GPUs, and Helios rack-scale systems, and to confirm that the Zen 7 generation arriving in 2028 will launch as three separate EPYC families rather than one. The company named Florence, Ferrara, and Fidenza in its launch release, extended its annual CPU, GPU, networking, and rack cadence out to 2030, and put its total addressable market at roughly $2 trillion in 2030. It also introduced a competitive yardstick it hasn't used before, claiming the most AI agents per watt, per dollar, and per rack, though its own endnotes state those agent counts are estimated from CPU thread resources used as a proxy. Three Zen 7 CPUs Florence carries fresh Zen 7 cores, a new set of AI compute extensions, and support for newer memory technologies, AMD chair and CEO Lisa Su said during the keynote. Ferrara is the AI host node portion, and it appears a second time further along the roadmap as the CPU inside the Helios 600 rack alongside MI600 Series GPUs and Pensando "Palma" and "Levanzo" networking. Fidenza, meanwhile, is the agentic sandbox product. AMD disclosed no core counts, no process node, and no socket for any of the three, and said only that Zen 7 uses leading-edge process technology. The fourth-gen EPYC generation, built on Zen 4, spanned Genoa, Bergamo, Genoa-X, and Siena across two sockets. The fifth-gen "Turin" generation then went the other way, folding Zen 5 and Zen 5c parts into a single 27-SKU stack on one socket with no separate cache-stacked or edge line at launch. Venice restarts the fan-out, with the 9006 series on the new SP7 socket now, and Venice-X arriving in 2027 with 1,152MB of 3D V-Cache, 96 cores, and a 5.15 GHz boost clock. Three named Zen 7 families at announcement, two years out, is a wider spread than AMD has ever opened a generation with. AMD's own portfolio endnote describes the EPYC range as covering general-purpose enterprise, cloud, telecom, SMB, and HPC systems, plus, as a distinct category, sandboxed agentic AI deployments and GPU head node servers. Su told analysts in May that AMD was already working with customers on architectures beyond Venice, without naming categories at the time. The Zen 7 lineup puts a name to those two AI-specific segments for the first time. Agents per rack AMD's main server CPU claim at the event is that sixth-gen EPYC enables the most agents per watt, per dollar, and per rack. Endnote 9xx6-012 in the launch release states that agent counts are estimates derived from available CPU thread resources used as a proxy under a consistent theoretical workload, and that real capacity varies with workload, model, memory, software, orchestration, and system configuration. The per-rack comparison behind it is core count at a 100 kW rack power envelope, pitting the 256-core EPYC 9996 against an 88-core Nvidia Vera, AMD's own 192-core EPYC 9965, and Intel's 128-core Xeon 6980P.
