AMD’s “Gorgon Halo” Unleashes 192GB Unified Memory, 160GB VRAM for Workstation-Class APUs
AMD has officially confirmed that its upcoming Ryzen AI MAX 400 series, codenamed “Gorgon Halo,” will support up to 192GB of unified memory on the same platform. According to a presentation slide shared by the company, the same system can allocate as much as 160GB of that memory as dedicated VRAM – a massive leap for integrated graphics.
The confirmation came alongside AMD’s Ryzen AI Halo workstation presentation, which currently uses the Strix Halo‑based Ryzen AI MAX+ 395 with 128GB of LPDDR5x‑8000 memory. Gorgon Halo is the direct successor to Strix Halo, keeping the same chiplet design but upgrading memory support and clock speeds.
What Gorgon Halo Brings
The new Ryzen AI MAX 400 series will feature:
- Up to 16 Zen 5 CPU cores and 32 threads
- CPU boost clock up to 5.2 GHz (versus 5.1 GHz on Strix Halo)
- Up to 40 RDNA 3.5 GPU Compute Units (same as Strix Halo)
- GPU boost clock up to 3.0 GHz (100 MHz higher than Strix Halo)
- XDNA 2 NPU delivering up to 55 TOPS (up from 50 TOPS)
The memory support is the headline feature: 192GB of LPDDR memory across a 256‑bit bus, with up to 160GB reserved for graphics. That would make Gorgon Halo systems capable of running large AI models, complex simulations, or rendering workloads that previously required discrete GPUs with massive VRAM pools.
SKU Lineup (Preliminary)
AMD’s slide lists several Gorgon Halo SKUs, including the Ryzen AI MAX+ 495 (16 cores, 5.2 GHz, 8065S graphics), MAX+ 492 (12 cores), MAX 490 (12 cores), MAX+ 488 (8 cores), and MAX 485 (8 cores). All models feature the same 55 TOPS NPU.
Comparing Gorgon Halo to Strix Halo
| Feature | Strix Halo (AI MAX+ 395) | Gorgon Halo (AI MAX+ 495) |
|---|---|---|
| CPU Cores | 16 Zen 4 | 16 Zen 5 |
| CPU Boost | 5.1 GHz | 5.2 GHz |
| GPU CUs | 40 RDNA 3.5 | 40 RDNA 3.5 |
| GPU Boost | 2.9 GHz | 3.0 GHz |
| NPU | 50 TOPS | 55 TOPS |
| Max Memory | 128GB LPDDR5x | 192GB LPDDR (? – likely LPDDR6) |
| Max VRAM Allocation | ~110GB | 160GB |
What This Means
For professionals working with AI, large datasets, or 3D rendering, a single chip with 160GB of VRAM opens new possibilities that previously required multi‑GPU workstations. The unified memory architecture also simplifies programming and reduces power consumption.

AMD has not yet announced availability of the Ryzen AI MAX+ 395‑based workstations (Strix Halo), let alone Gorgon Halo systems. The slide suggests the new platform is in development and likely targeting late 2026 or 2027.
For now, the numbers are impressive: 192GB of total memory, 160GB of which can be used as VRAM, all inside an APU form factor. Gorgon Halo is shaping up to be a true workstation monster.
