Market
Commercial AI PC / Mobile Workstation
The AMD Ryzen AI Max PRO 485 is an 8-core, 16-thread Zen 5 APU for commercial AI PCs and mobile workstations, featuring a 16-CU RDNA 3.5 integrated GPU, an XDNA 2 NPU, and support for up to 192GB of unified LPDDR5X memory.
As the entry-level model in the Ryzen AI Max PRO 400 family, the 485 retains the defining feature of the Gorgon Halo silicon: a 256-bit memory bus supporting up to 192GB of LPDDR5X. This allows up to 160GB to be allocated as VRAM for running large language models locally. It pairs this massive memory capacity with 8 Zen 5 CPU cores, a 16-CU RDNA 3.
5 integrated GPU, and a 50 TOPS XDNA 2 NPU. By reducing the core count, AMD offers a more budget-friendly option for enterprise users and developers who prioritize memory capacity over multi-threaded compute density, making it ideal for "Agent PCs" and AI-focused commercial devices.
Specifications
Performance
Solid single-core and moderate multi-core performance handles commercial applications well, though it lags behind 12+ core models in heavy rendering.
Good for running several VMs, greatly benefiting from the massive memory pool rather than raw CPU compute.
The 16-CU integrated GPU is suitable for casual or older games but struggles with modern AAA titles at high settings.
With fewer cores to feed, the 485 often operates more efficiently than the 490 or 495 under similar workloads.
- •16 Compute Units provide basic graphical capability.
- •Suitable for 1080p Low/Medium settings in e-sports titles.

Architecture Overview
The Ryzen AI Max PRO 485 utilizes the Gorgon Halo SoC, fabricated on TSMC's 4nm FinFET process. Unlike standard mobile processors that are constrained by a 128-bit memory bus, this chip features a 256-bit interface. This wide path is essential for feeding up to 192GB of LPDDR5X memory into a unified architecture where the CPU, GPU, and NPU share the same memory pool. The CPU complex consists of 8 Zen 5 cores, providing a balance of single-threaded speed and multi-threaded capability without the thermal density of the 16-core variant. The integrated Radeon graphics are scaled down to 16 Compute Units based on RDNA 3.5, sufficient for display output and hardware acceleration. The XDNA 2 NPU provides 50 TOPS of dedicated AI compute, ensuring the processor meets the requirements for modern AI PCs while keeping power consumption low.

History
The Ryzen AI Max PRO 485 represents the democratization of AMD's Halo architecture, which originated with the Strix Halo designs aimed at combining desktop-class memory capacity with mobile portability. As AI workloads evolved to require massive context windows, the 128GB limit of the previous generation became a bottleneck for local LLM development. AMD introduced the Gorgon Halo refresh specifically to push the boundary to 192GB.
The 485 emerges as the accessible entry point to this ecosystem. By retaining the expensive memory controller and I/O die while reducing the CPU core count to 8, AMD created a chip that lowers the barrier to entry for high-memory AI workstations. This allows enterprise customers to deploy "Agent PCs" at a lower price point, focusing budget on the expensive memory modules rather than sheer CPU core count.
Improvements over Previous Generation
- Increased maximum memory support from 128GB to 192GB.
- Higher memory speed support (LPDDR5X-8533 vs LPDDR5X-8000).
- Updated RDNA 3.5 integrated graphics.
- Upgraded XDNA 2 NPU for higher AI TOPS.
