HP Z2 Mini G1a

What it is

HP’s Strix Halo mini workstation. Top SKU is the 16-core Ryzen AI Max+ PRO 395 with Radeon 8060S (40 RDNA 3.5 CUs), up to 128GB of soldered LPDDR5X-8000/8533 on a ~256 GB/s bus, dual M.2 (RAID capable, up to 8TB total in some configs), 2.5GbE, Wi-Fi 7, dual Thunderbolt 4 / USB4, and an internal 300W PSU. Chassis is tool-free to open, VESA/under-desk mountable, and sold with Windows 11 Pro plus HP’s enterprise stack (Wolf Security, Performance Advisor for VRAM allocation). Memory is soldered; you choose 16–128GB at order time. This page is the 128GB machine unless noted.

Who it is for

People who want a 24B–70B local model (or large MoE) in a certified mini workstation they can put on a corporate desk or mount behind a monitor, and who are fine with ROCm / llama.cpp / Vulkan instead of CUDA. Useful if you need ISV certification, longer warranty options, or the ability to allocate up to 96GB to the iGPU via BIOS/HP tools. Wrong if you need dual 10GbE, full discrete-GPU bandwidth, user-upgradeable RAM, or the absolute lowest street price for this silicon.

What it actually runs

• Comfortable: 24B–32B dense at usable speed; smaller MoE models at high token rates.
• Possible: 70B-class dense and larger sparse MoE (120B-class reported) when you buy 128GB. Capacity is the win; decode is still limited by the ~256 GB/s bus. Dense 70B lands nearer single-digit tokens per second on tuned Linux setups; some MoE configs report 20–40+ tok/s depending on quant and context.
• Not the win: training, CUDA-only stacks, or expecting discrete-GPU token rates. Ignore vendor “125 TOPS” and “rival two high-end GPUs” slides.

Standout details

• Price snapshot early Sep 2026: base and mid configs tracked from roughly $2,000–$3,000; 128GB Max+ 395 configs commonly $3,000–$5,000 street depending on storage, warranty, and channel (HP.com discounts, B&H, Amazon, eBay). List prices run higher. Stock and promotions move.
• Memory is soldered LPDDR5X. Up to 96GB can be allocated exclusively to the GPU. Pick 128GB or do not buy this for large models. ECC options exist on some configs.
• Networking is 2.5GbE + Wi-Fi 7, not dual 10GbE. Dual Thunderbolt 4 is the expansion path for external storage or docks.
• Same chip class and bandwidth ceiling as Framework Desktop, EVO-X2, GTR9 Pro, and MS-S1 MAX.
• Fans can get loud under sustained high-power load. Cooling is competent for the form factor but not silent-desktop quiet in performance mode. Tool-free access and dual M.2 are practical for a sealed-looking mini.

Honest verdict

The enterprise Strix Halo mini. Buy the 128GB config if you specifically want HP’s Z platform, certification, mount options, and support around the same silicon everyone else sells. Same bandwidth ceiling as every other Max+ 395 box. If you want dual 10GbE, look at GTR9 Pro or MS-S1 MAX. If you want repairability, get Framework. If you want CUDA, shop Spark / GX10.
