The leaked AMD slides were not a confirmed specification sheet. Reported in September 2023 after appearing in a Moore’s Law Is Dead video, they allegedly outlined Zen 5 and Zen 6 improvements including wider execution resources, larger caches, higher IPC, and much higher server core counts. AMD never publicly authenticated the material, and contemporary reporting indicated that it was focused primarily on EPYC enterprise processors rather than mainstream Ryzen chips.
With hindsight, parts of the Zen 5 story were directionally consistent with AMD’s later disclosures. Zen 5 subsequently shipped in Ryzen 9000, Ryzen AI 300, and EPYC Turin products, while AMD officially identified Zen 6 EPYC Venice as a 2nm-class server architecture planned for 2026. However, the leaked core counts, cache details, process references, and consumer configurations should still be treated as unverified or product-specific.
What appeared in the leaked AMD slides?
The material reportedly consisted of two alleged internal AMD slides covering Zen 5 and Zen 6 architectural targets. The slides were shown publicly by Moore’s Law Is Dead and reported by Tom’s Hardware in September 2023.
The claims covered more than headline IPC figures. They reportedly included front-end and execution-engine changes, cache and branch-prediction improvements, larger core complexes, possible process-node transitions, and server-oriented features such as FP-512 and AI-related support.
#1 Best Overall
- The world’s fastest gaming processor, built on AMD ‘Zen5’ technology and Next Gen 3D V-Cache.
- 8 cores and 16 threads, delivering +~16% IPC uplift and great power efficiency
- 96MB L3 cache with better thermal performance vs. previous gen and allowing higher clock speeds, up to 5.2GHz
- Drop-in ready for proven Socket AM5 infrastructure
- Cooler not included
The important qualification is evidence quality: AMD did not authenticate the slides. Even if some information came from genuine AMD planning material, a roadmap target may not represent final silicon, every product family, or a commitment to a particular launch configuration.
What the alleged Zen 5 slide claimed
| Area | Reported claim | How to interpret it |
|---|---|---|
| IPC | Approximately 10–15% or more over Zen 4 | A target, not an independently measured result |
| L1 data cache | 48KB, compared with 32KB for Zen 4 | Reported slide detail; not a universal Ryzen specification |
| Front end | Two basic-block fetch units | Unverified leak detail |
| Dispatch and rename | Eight-wide | Unverified leak detail |
| Integer execution | Six ALUs | Unverified leak detail |
| Load and store | Four load units and two store units | Unverified leak detail |
| Branch prediction | Larger BTB, higher accuracy, and fewer bubbles | Architectural target described by the slide |
| Scheduling | Larger scheduler and more unified integer scheduling | Slide-level claim |
| Prefetching | Additional data-prefetch improvements | No detailed mechanism was publicly established |
| Core complex | Possible increase from eight to 16 cores | Primarily relevant to server designs |
| Vector support | Some models potentially supporting 512-bit floating point | Not a general Ryzen desktop claim |
These changes describe ways a processor could improve work completed per clock: fetching more useful instructions, dispatching more operations, keeping execution units supplied, predicting branches more accurately, and reducing stalls caused by data access. None of those individual claims establishes the performance of a retail CPU.
What the alleged Zen 6 slide claimed
The Zen 6 section reportedly promised at least a 10% IPC improvement, FP16 support aimed at artificial-intelligence and machine-learning workloads, a new memory profiler, and another substantial increase in core density. One reported projection moved from 16 to 32 cores per CCD. Early reporting also associated Zen 6 with possible 3nm or 2nm manufacturing.

A “32-core CCD” reference could describe a server compute chiplet, a density-optimized design, or an engineering target—not a future Ryzen desktop processor. Likewise, early process-node references may have applied to a particular compute die or product family rather than an entire CPU package.

Why the EPYC-versus-Ryzen distinction matters
The leak was reported as being aimed at EPYC enterprise CPUs, or at least heavily influenced by server designs. That matters because EPYC and Ryzen are built around different priorities.
- EPYC: emphasizes core density, memory bandwidth, I/O, virtualization, throughput, and sustained multi-socket or data-center workloads.
- Ryzen desktop: must balance performance, clock speed, power, thermals, socket constraints, cost, and gaming responsiveness.
- Ryzen mobile: adds battery life, integrated graphics, acceleration hardware, and strict thermal limits to the design problem.
A server processor can therefore use a different cache arrangement, vector implementation, memory subsystem, chiplet layout, and frequency target from a desktop processor using the same broad Zen generation. The reported FP-512 support, very high core counts, and server-scale memory features should not be copied into a claim about mainstream Ryzen.
Zen 5 shipped: what survived the rumor cycle?
Zen 5 became a real, shipping architecture rather than a roadmap rumor. AMD’s product families include Ryzen 9000 desktop processors, Ryzen AI 300 mobile processors, and EPYC Turin server processors. AMD also used both standard Zen 5 and density-optimized Zen 5c implementations.
In Ryzen AI 300 launch material, AMD claimed a 16% IPC improvement over Zen 4. That is broadly in the vicinity of the leaked 10–15% target, but the similarity does not authenticate the slides. AMD’s figure is also a vendor claim measured under a defined methodology; it should not be read as a guarantee that every application runs 16% faster.
Rank #3
- Can deliver fast 100 plus FPS performance in the world's most popular games, discrete graphics card required
- 6 Cores and 12 processing threads, bundled with the AMD Wraith Stealth cooler
- 4.2 GHz Max Boost, unlocked for overclocking, 19 MB cache, DDR4-3200 support
- For the advanced Socket AM4 platform
The mobile lineup demonstrated why “Zen 5” is not one uniform product configuration. The Ryzen AI 9 HX 370 used 12 cores and 24 threads: four standard Zen 5 cores plus eight Zen 5c cores. AMD describes Zen 5c as based on the same underlying Zen 5 architecture while being optimized for density and generally operating at lower clock speeds. The platform also included an XDNA 2 NPU and RDNA 3.5 graphics, but those are platform features rather than CPU-core features. Tom’s Hardware’s Ryzen AI 300 coverage details that mixed-core design.
Zen 5’s shipping products therefore support some broad themes from the leak—higher IPC, multiple implementations, and strong attention to density—but they do not validate every reported execution-unit count, cache size, or 16-core consumer CCX prediction.
IPC is not the same as application speed
IPC, or instructions per clock, is normally compared at the same clock frequency and under a defined test method. It is useful for judging an architectural generation, but the result varies by workload.
Real-world performance also depends on clock speed, power limits, thermal conditions, memory latency and bandwidth, cache behavior, SMT scaling, compiler decisions, software optimization, and whether a workload uses vector or floating-point instructions. A processor with a stated 16% IPC gain will not automatically deliver 16% higher frame rates, compile times, or rendering performance in every application.

Zen 6 is now officially on AMD’s roadmap
Zen 6 is no longer only a leaked architecture. AMD’s Advancing AI 2025 presentation identifies EPYC Venice as a Zen 6 product, associates it with a 2nm-class process, lists up to 256 cores, and gives 2026 as the expected timeframe. AMD’s roadmap material also notes that engineering projections can change before commercial availability.
The “up to 256 cores” figure must be read in its server context. A maximum-core Venice configuration uses dense Zen 6c cores; standard Zen 6 configurations have lower maximum core counts. It is not evidence that a Ryzen desktop CCD will contain 32 cores.
Separate reporting on an AMD developer document describes Zen 6 as a ground-up, throughput-oriented redesign with an eight-slot dispatch engine and strong vector capabilities. Tom’s Hardware’s report is useful context, but it is not a complete public Zen 6 specification and may describe server-oriented implementation details.

Which Zen 6 products are associated with the roadmap?
AMD and subsequent reporting have associated Zen 6 with EPYC Venice for servers, Olympic Ridge for desktop Ryzen, and Medusa Point for mobile Ryzen. Product names and roadmap associations are not the same as completed product announcements.
Best Value
- Pure gaming performance with smooth 100+ FPS in the world's most popular games
- 6 Cores and 12 processing threads, based on AMD "Zen 5" architecture
- 5.4 GHz Max Boost, unlocked for overclocking, 38 MB cache, DDR5-5600 support
- For the state-of-the-art Socket AM5 platform, can support PCIe 5.0 on select motherboards
- Cooler not included
Final core counts, launch order, clocks, cache topology, sockets, motherboard compatibility, X3D versions, and the precise division between Zen 6 and Zen 6c remain subject to official product disclosures. Future Ryzen products should not automatically inherit specifications disclosed for EPYC Venice.
What remains unconfirmed?
- Whether the original slides were obtained directly from AMD.
- Whether every slide was current when shown or represented final silicon.
- The final Ryzen Zen 6 core counts and CCD structure.
- Exact desktop and mobile launch dates.
- Consumer socket and motherboard compatibility.
- Final clock speeds and cache arrangements.
- The timing and design of any Zen 6 X3D products.
- Whether FP16, FP-512, or the reported memory profiler will appear across all Zen 6 products.
- Whether every leaked execution-resource and cache number applies to shipping products.
What this means for CPU buyers
Buyers who need a desktop system now should evaluate current Ryzen 9000 processors using independent benchmarks, platform cost, power consumption, and workload fit—not leaked Zen 6 numbers. Buyers considering a Ryzen AI laptop should distinguish CPU performance from the system’s NPU, integrated graphics, memory configuration, and battery behavior.
Waiting for Zen 6 can make sense for readers who do not need a system immediately and are willing to wait for confirmed pricing, availability, platform compatibility, and independent testing. Current AM5 compatibility should not be treated as a guarantee that every future Zen 6 desktop chip will work in every existing motherboard.

Actual procurement decisions still require validated OEM systems, memory support, power and cooling requirements, pricing, and benchmark data.
The verdict
The 2023 slides are best understood as an important but unverified glimpse at AMD’s architectural direction. Their double-digit Zen 5 IPC target ended up broadly near AMD’s later 16% claim, and their emphasis on wider execution and greater density fits the evolution AMD ultimately showed. But the leak did not predict a single universal Zen 5 or Zen 6 product.
Zen 5 is now a shipping architecture across desktop, mobile, and server families. Zen 6 is officially tied to EPYC Venice, a 2nm-class, 2026 server roadmap product with up to 256 cores. The remaining Ryzen details are not established until AMD announces them and independent testing verifies how the architecture performs.
