HP Z2 Mini G1a Workstation (Ryzen AI Max+ PRO 395, 128GB)

The HP Z2 Mini G1a is a mini workstation on AMD's Ryzen AI Max+ PRO 395 with 128GB of unified memory and HP Z service options. It is for firms that must keep client data in the building. The one thing to know: unified memory lets it hold large mixture-of-experts models; dense 70B models are slow and there is no CUDA.

Can the Z2 Mini G1a run large models without a graphics card?

• StorageReview (Aug 2025), Editor's Choice: gpt-oss-120b at "close to 40 tokens/sec", a 70B-class dense model at 4.24 tokens/s, 96GB assigned to the GPU, and noticeable fan noise.
