AMD Ryzen AI Max+ 395 (Strix Halo)
The Ryzen AI Max+ 395, codenamed Strix Halo, is AMD's 16-core Zen 5 processor with an integrated 40-compute-unit Radeon 8060S GPU and a 256-bit LPDDR5x-8000 memory interface supporting up to 128 GB of soldered unified memory. It is sold inside laptops and mini PCs (Framework Desktop, GMKtec EVO-X2, Minisforum, Beelink and others), not as a retail chip, and its draw for AI work is that one box can hold models that need far more than a 32 GB discrete card. It is the x86 alternative to the DGX Spark class: more flexible, no CUDA, and memory bandwidth in the same range. It is a development and small-team inference box, not a cluster node.
- Bandwidth, not capacity, is the ceiling: 256 GB/s theoretical is comparable to the DGX Spark's 273 GB/s, so large dense models decode slowly. Mixture-of-experts models suit it better than dense ones.
- The 256 GB/s figure is arithmetic from the interface (8000 MT/s on 256 bits), not an AMD-published specification; measured bandwidth is lower.
- It is not CUDA. Check your inference stack (llama.cpp with Vulkan or ROCm, vLLM) supports the Radeon 8060S on your OS before standardising.
- How much of the 128 GB the GPU may use depends on OS and driver settings; we did not verify the cap.
- Single-box only: there is no scale-out NIC in the chip, so networking depends on the mini PC's USB4 or add-in options.
What is Strix Halo?
Strix Halo is the former codename for the Ryzen AI Max series. The Ryzen AI Max+ 395 is its top part: 16 Zen 5 cores, a 40-CU Radeon 8060S GPU and up to 128 GB of unified LPDDR5x.
How much does a 128 GB Ryzen AI Max+ 395 mini PC cost?
Reported prices in late September 2026 ran $3,324 to $4,349, roughly double the mid-2026 level because of the DRAM shortage. Check vendor pages.
What is the memory bandwidth?
256 GB/s theoretical, derived from LPDDR5x-8000 on a 256-bit interface. AMD's page lists the memory type and speed but not a bandwidth figure.
Strix Halo vs DGX Spark?
Both offer 128 GB of unified memory at similar bandwidth. The Spark has CUDA and ConnectX-7 networking; Strix Halo is x86, runs Windows and Linux, and has no CUDA.
