AMD has officially unveiled its Ryzen AI MAX 400 SoCs, which feature support for up to 192 GB of memory to tackle 300B+ AI LLMs.
AMD's Biggest Upgrade With Its New Ryzen AI MAX 400 Halo SoCs Is The Massive 192 GB Unified Memory Which Supports Over 300B AI LLMs
The AMD Ryzen AI MAX PRO 400 & Ryzen AI MAX 400 SoCs are part of the new Gorgon Halo family. These SoCs feature the Zen 5 core architecture, RDNA 3.5 graphics architecture, and XDNA 2 AI NPU. While the architecture remains the same as the Ryzen AI MAX 300 lineup, there are various updates across the board, such as higher clocks and increased memory support.
Some of the highlights of the AMD Ryzen AI MAX 400 family include:
- Systems powered by Ryzen AI Max PRO 400 Series processors will be available from major OEM partners, including ASUS, HP, and Lenovo, starting Q3 2026.
- Enables developers and creators to run large local AI models, including 300B+ parameter LLMs,
on an x86 client processor. - Supports concurrent agentic AI workflows with up to 192GB of unified memory for multiple local
AI agents. - Combines AI acceleration, graphics, and compute performance in a single platform for
professional AI and creative workloads. - Delivers workstation-class performance for design, rendering, simulation, and engineering
applications.
The AMD Ryzen AI MAX 400 SoC family will include a total of three chips at launch. These include the Ryzen AI MAX+ PRO 495, Ryzen AI MAX+ PRO 490, and the Ryzen AI MAX+ PRO 485. All three Ryzen AI MAX 400 chips match the core configurations of existing Ryzen AI MAX 300 SKUs, but with higher clocks on the CPU and GPU.
The memory upgrade is obviously the biggest one. With up to 192 GB of unified memory, the Ryzen AI MAX 400 chips will be able to support massive AI LLMs locally. Additionally, users can also allocate up to 160 GB of VRAM to the GPU itself, a big increase versus the current 112 GB that can be allocated across 128 GB setups.
In terms of specifications, the flagship AMD Ryzen AI MAX+ 495 features 16 "Zen 5" CPU cores, a Radeon 8065S iGPU with 40 compute units. The CPU is now clocked at 100 MHz higher base and boost clocks to 3.1 & 5.2 GHz, respectively. The GPU is also clocked 100 MHz higher, now hitting 3.0 GHz, which should offer a nice boost in performance. The NPU is rated at 55 TOPS. Lastly, the chips will feature a base TDP of 55W, which can be adjusted to 45W, and up to 120W.
The following is what the full lineup should look like:
AMD Ryzen AI MAX 400 "Gorgon Halo" APU Lineup:
| SKU Name | Architectures | CPU Cores | Max Clock | Cache | GPU Cores | TDP |
|---|---|---|---|---|---|---|
| Ryzen AI Max+ 495 | Zen 5 / RDNA 3.5 | 16 / 32 | 5.2 GHz | 80 MB | 40 CUs (Radeon 8065S) | 45-120W |
| Ryzen AI Max 490 | Zen 5 / RDNA 3.5 | 12 / 24 | 5.0 GHz | 76 MB | 32 CUs (Radeon 8050S) | 45-120W |
| Ryzen AI Max 485 | Zen 5 / RDNA 3.5 | 8 / 16 | 5.0 GHz | 40 MB | 32 CUs (Radeon 8050S) | 45-120W |
As for launch, the AMD Ryzen AI MAX 400 SoCs are expected to roll out in the first systems by Q3 2026 with major partners including ASUS, HP, and Lenovo. The standard Ryzen AI 400 "Gorgon" SoCs are also expected to roll out soon, since they will be tackling Intel's Core Ultra Series 3 "Panther Lake" chips, which will hit retail shelves next week.
