HP's Z2 Mini is the Strix Halo for businesses that buy through procurement: Ryzen AI Max+ PRO 395, 128 GB of LPDDR5X (HP quotes 8533 MT/s — a spec bump over the platform's usual 8000), 2 TB NVMe, Wolf security stack and 3-year warranty options, with genuine UK stock on hp.com.
It costs more than the Chinese mini-PCs but it is the only Strix box with a tier-1 OEM support story — usually the deciding factor when the machine is going into an office rather than a lab.
vs its siblings: The only Strix Halo with a tier-1 OEM support story and clean UK supply.

Where it shines
- Tier-1 OEM warranty and UK stock — procurement-friendly
- gpt-oss-120b at 30–55 tok/s for under £2.7k
- 2.7 L, quiet, office-appropriate
- Slightly faster memory than the platform standard
The trade-offs
- 256 GB/s bandwidth — dense models and long prompts are slow
- ROCm still trails CUDA; Vulkan is the reliable path
- BIOS locks down some tuning the enthusiast boxes allow
- 192 GB Gorgon Halo refresh lands Q3 2026 — buy knowing that

Understanding AMD Strix Halo
Ryzen AI Max+ 395
AMD's Ryzen AI Max+ 395 ('Strix Halo') puts 16 Zen 5 cores, a 40-CU Radeon 8060S GPU and up to 128 GB of unified LPDDR5X-8000 on one package. Framework, HP, GMKtec, Beelink, Corsair and AMD itself all ship it as a compact desktop, from roughly £1,700 to £2,700 in the UK.
It is a mixture-of-experts machine: gpt-oss-120b runs at 30–55 tok/s and even Qwen3-235B squeezes in at 3-bit (~11 tok/s), but dense 70B models crawl at ~5 tok/s because 256 GB/s of bandwidth is the ceiling. The software stack (Vulkan / ROCm / llama.cpp / LM Studio) is genuinely usable in 2026 but remains a step behind CUDA for production serving and fine-tuning.
It is the right first box for proving local AI on real workloads before committing to bigger silicon — and the refresh is close: AMD's Ryzen AI Max 400 series ('Gorgon Halo', announced May 2026) lifts the ceiling to 192 GB with OEM systems from Q3 2026.
