AMD has introduced its Ryzen AI MAX 400 family, also known as Gorgon Halo, with a major focus on local AI workloads. The new chips support up to 192GB of unified memory, which AMD says allows a single x86 client processor to run AI models with more than 300 billion parameters locally.
The new lineup keeps the same main architecture as Ryzen AI MAX 300, using Zen 5 CPU cores, RDNA 3.5 graphics, and an XDNA 2 AI NPU. The bigger changes come from higher clocks, more memory support, and better headroom for large local AI models and agentic AI workflows.
The biggest upgrade is memory, not a full architecture change
AMD says Ryzen AI MAX 400 systems will support concurrent agentic AI workflows with up to 192GB of unified memory. Developers can also allocate up to 160GB of memory to the GPU, which is a large increase over the 112GB limit available on current 128GB systems.
The flagship Ryzen AI MAX Plus 495 includes 16 Zen 5 CPU cores, 32 threads, Radeon 8065S graphics with 40 RDNA 3.5 compute units, and a 55 TOPS NPU. AMD has raised CPU clocks to 3.1GHz base and 5.2GHz boost, while the GPU can now reach 3.0GHz. The chip has a 55W base TDP and can be configured from 45W up to 120W.
| Chip | CPU cores | Max clock | Cache | GPU | TDP |
|---|---|---|---|---|---|
| Ryzen AI MAX Plus 495 | 16 cores and 32 threads | 5.2GHz | 80MB | Radeon 8065S, 40 CUs | 45W to 120W |
| Ryzen AI MAX 490 | 12 cores and 24 threads | 5.0GHz | 76MB | Radeon 8050S, 32 CUs | 45W to 120W |
| Ryzen AI MAX 485 | 8 cores and 16 threads | 5.0GHz | 40MB | Radeon 8050S, 32 CUs | 45W to 120W |
AMD is aiming these processors at developers, creators, and professionals who need workstation class performance in compact systems. The company says the chips can handle local AI agents, creative workloads, rendering, simulation, engineering work, and other tasks that need CPU, GPU, and AI acceleration in one platform.
Systems using Ryzen AI MAX PRO 400 processors are expected to arrive from partners such as ASUS, HP, and Lenovo starting in the third quarter of 2026. AMD is also preparing standard Ryzen AI 400 Gorgon chips as competition with Intel’s Core Ultra Series 3 Panther Lake lineup increases.
This story is related to the earlier Ryzen AI Halo developer platform update, but it is not the same report. The earlier article focused on the $3,999 developer system with Ryzen AI MAX Plus 395 and 128GB of memory. This one focuses on the newer Ryzen AI MAX 400 chips, where the main upgrade is 192GB unified memory and support for 300B plus local AI models.
