Ryzen AI Max PRO 400: AMD's 40-CU Halo APU
Zen 5 meets massive integrated RDNA 3.5 graphics and up to 192GB unified memory in AMD's Gorgon Halo.
Start here
The AMD Ryzen AI Max PRO 400 Series (codenamed Gorgon Halo) redefines what an APU can do. Launching in Q3 2026, these chips integrate up to 16 Zen 5 cores with a massive 40-CU integrated GPU. By utilizing up to 192GB of unified memory, users can allocate an astonishing 160GB as VRAM — completely bypassing traditional PCIe bottlenecks for local AI workloads and rendering.
The Ryzen AI Max PRO 400 Lineup
AMD has confirmed three specific SKUs for the commercial and mobile workstation refresh. The primary differentiator is the core count, GPU scale, and NPU performance.
| Processor | Cores / Threads | Graphics (CUs) | NPU (TOPS) |
|---|---|---|---|
| Ryzen AI Max+ PRO 495 | 16 / 32 (Zen 5) | Radeon 8065S (40 CUs @ 3.0 GHz) | 55 TOPS |
| Ryzen AI Max PRO 490 | 12 / 24 (Zen 5) | Radeon 8050S (32 CUs @ 2.8 GHz) | 50 TOPS |
| Ryzen AI Max PRO 485 | 8 / 16 (Zen 5) | Radeon 8050S (32 CUs @ 2.8 GHz) | 50 TOPS |
160GB of VRAM: Why unified memory matters
Standard desktop architectures split memory: the CPU uses system RAM (DDR5), and the dedicated GPU uses its own VRAM (GDDR6). Moving data between them across a PCIe bus takes time and creates a bottleneck for massive AI models.
The Ryzen AI Max PRO 400 series uses unified memory — the CPU and the integrated GPU share the exact same pool of LPDDR5X. Because the platform supports up to 192GB total, you can allocate up to 160GB of it as VRAM for the integrated Radeon GPU.
- For Local AI: This makes it the world's first x86 client processor capable of running 300-billion-parameter LLM models locally without crashing due to out-of-memory errors.
- For Creators: 3D artists can load massive, uncompressed scenes into VRAM that would normally require a multi-thousand-dollar workstation GPU.
A 40-CU APU: The end of budget dedicated GPUs?
Historically, integrated graphics were meant for office work or 720p low-settings gaming. The flagship Radeon 8065S packs 40 RDNA 3.5 Compute Units running at 3.0 GHz.
For context, 40 CUs is more raw graphics silicon than many mid-range dedicated GPUs from just a few years ago. While memory bandwidth (LPDDR5X vs GDDR6) will still limit it compared to high-end discrete cards, this APU represents a massive leap for Small Form Factor (SFF) builds and thin laptops, offering legitimate 1080p and 1440p gaming performance without a dedicated graphics card.
Who should not buy this class of chip
- Desktop gamers who can fit a discrete GPU — dedicated cards still win on bandwidth and driver maturity.
- Buyers who need a standard ATX upgrade path today — halo APUs target OEM/SFF and mobile workstations first.
- Anyone expecting retail boxed CPUs on every shelf in Q1 — launch is partner systems in Q3 2026.
- Budget builders — LPDDR5X platforms are premium; Ryzen 5 + used GPU may cost less.
FAQ
- What is the Ryzen AI Max PRO 400 Series?
- Codenamed 'Gorgon Halo', the Ryzen AI Max PRO 400 series is AMD's latest lineup of workstation and commercial APUs. They combine Zen 5 CPU cores with massive RDNA 3.5 integrated graphics and support up to 192GB of unified memory.
- What are the specs of the Ryzen AI Max+ PRO 495?
- The flagship 495 features 16 Zen 5 cores (32 threads), 80MB of cache, a 55 TOPS NPU, and a staggering 40-CU Radeon 8065S integrated GPU clocked at 3.0 GHz.
- How much VRAM does the Ryzen AI Max PRO 400 support?
- Because the series uses unified memory (up to 192GB total), users can allocate up to 160GB of that system RAM directly as VRAM. This is a game-changer for local AI models (LLMs) and massive 3D rendering workloads.
- Is the Ryzen AI Max PRO 400 good for gaming?
- Yes. The 40-CU Radeon 8065S integrated GPU inside the flagship model offers performance that rivals mid-range dedicated graphics cards, making it an incredibly powerful solution for Small Form Factor (SFF) gaming PCs and thin-and-light laptops.
- When is the Ryzen AI Max PRO 400 release date?
- Systems powered by the Ryzen AI Max PRO 400 series, including mobile workstations from partners like HP and Lenovo, are scheduled to launch in the third quarter (Q3) of 2026.
- How does it compare to the previous Ryzen AI Max 300?
- The 400 series increases maximum unified memory from 128GB to 192GB (and VRAM allocation from 96GB to 160GB). It also introduces higher clocks and the upgraded 40-CU Radeon 8065S GPU on the flagship tier.
Bottom line
The AMD Ryzen AI Max PRO 400 series proves that the future of commercial PCs and mobile workstations lies in unified memory. By combining 16 Zen 5 cores, a 40-CU GPU, and the ability to address 160GB of VRAM on a single package, AMD has created a true "Halo" product that will redefine what thin laptops and mini PCs can achieve in late 2026.
