The next AMD Ryzen AI Halo developer platform carries up to 192GB of unified memory, enough that AMD says it can hold language models of 300 billion parameters and larger at 4-bit quantization. It is a compact desktop machine for developers and creators who want to run AI work on their own hardware instead of renting cloud capacity.
The system is built around the Ryzen AI Max+ PRO 495 processor. According to AMD, the chip combines up to 16 Zen 5 CPU cores, 40 RDNA 3.5 graphics compute units and an NPU rated at up to 55 TOPS, all sharing up to 192GB of LPDDR5x memory. Up to 160GB of that pool can be assigned to the GPU as video memory. AMD adds that the shared pool lets developers run several large agents at once, each with its own KV cache.
Memory capacity is the headline, and the arithmetic explains why. A 300-billion-parameter model at 4 bits needs roughly 150GB just for its weights, so the 160GB GPU allocation leaves only modest room for context. That makes the 192GB ceiling a practical requirement for the largest models rather than a spec-sheet flourish, and it separates the Halo platform from typical discrete graphics cards, which top out at a fraction of that capacity.
For speed, AMD points to its own September 2026 testing in ComfyUI 0.37 across image, video, music and 3D generation workloads. Against a laptop with Intel's Core Ultra X9 388H and a MacBook Pro with an Apple M5 Pro, AMD reports higher relative throughput for its own system, and says several workloads would not run on the Apple machine at all. The post shows relative charts without absolute figures. The AMD system used 192GB of memory while both comparison machines had 64GB, so some of the gap likely reflects capacity as much as silicon.
The software side is a curated bundle. The AMD Ryzen AI Developer Center gathers preloaded apps and models, guided AI Playbooks and a validated Best-Known Configuration of ROCm, drivers, frameworks and models that owners can update or restore. Orders for the AMD Ryzen AI Halo are open through Micro Center, and Windows-based units with the same processor and Windows Project Zenith are listed as coming soon. AMD's post gives no price for either version.
