A 300W workstation chassis with 96GB of graphics memory
The HP Z2 Mini G1a measures 6.61 x 7.87 x 3.37 inches and weighs about 5.84 pounds, small enough for a desk yet deep enough to house serious cooling for workstation-class hardware. The chassis carries HP’s diamond-pattern ventilation grille on the front panel, and a finger latch on the top cover opens it for internal maintenance without tools. The front panel provides a USB-C port with 10Gbps data transfer and DisplayPort alternate mode, a USB-A 10Gbps port, and a combination headphone/microphone jack. The rear panel holds two USB4 Type-C ports (40Gbps, Thunderbolt 4 compatible), two Mini DisplayPort 2.1 outputs, four USB-A ports (two at 10Gbps, two at 480Mbps), and the 2.5 Gigabit Ethernet port. Two customizable Flex IO slots allow configurations with additional HDMI, VGA, serial, or USB ports depending on deployment requirements.
The AMD Ryzen AI Max+ PRO 395 brings 16 Zen 5 cores and 32 threads with boost clocks reaching 5.1 GHz. The integrated Radeon 8060S graphics uses RDNA 3.5 architecture with 40 compute units, drawing from the same pool of LPDDR5X memory as the CPU in AMD’s unified memory architecture. NotebookCheck’s testing showed the system handling professional workloads with performance comparable to high-end mobile workstations. Allocating up to 96GB of the 128GB system memory to the GPU puts models within reach that would otherwise need expensive discrete GPUs with dedicated VRAM. For practical benchmarks and software guidance on running LLMs with this class of hardware, see our Strix Halo local LLM inference guide.
Wireless duties fall to WiFi 7 (802.11be) and Bluetooth 5.4, with the 2.5 Gigabit Ethernet port for wired networking. The dual M.2 2280 slots support PCIe 4.0 NVMe drives and can be set as RAID 0 for speed or RAID 1 for redundancy, up to 8TB across the pair. Swapping drives means lifting the top cover, no screwdriver involved, but all memory is soldered to the motherboard and cannot be upgraded after purchase. For organizations requiring additional connectivity, the Flex IO system allows mixing and matching ports including options for 10 Gigabit Ethernet, multiple HDMI outputs, or legacy serial connections.
Reviewer Insights
Andrew’s Perspective
Andrew positioned the HP Z2 Mini G1a as a “Mac Studio Killer” in his comprehensive hands-on review. His testing covered unboxing, internal inspection, performance benchmarks, thermal behavior, and acoustic measurements. He was particularly impressed by the 128GB RAM configuration’s potential for AI and LLM work, noting that “the more RAM, the better” when running large language models locally.
Andrew’s benchmark results showed the system handling Time Spy stress testing with a 97% passing score and virtually no thermal throttling under sustained load. However, he measured fan noise reaching as high as 70 dB under maximum load, which he characterized as significantly louder than competing mini PCs. He appreciated the toolless chassis entry, internal power supply eliminating external bricks, and the dual USB4 ports providing 40Gbps connectivity.
Matt Talks Tech’s Analysis
Matt Talks Tech compared the Z2 Mini G1a (the Ryzen AI Max+ PRO 395, 64GB) directly against Apple’s M4 Pro Mac Mini, including Cyberpunk 2077 gaming. He noted that “The Radeon 8060S iGPU performs near to a laptop equivalent of the Nvidia RTX 4070,” validating the graphics capability for both productivity and gaming.
The review highlighted that the Z2 Mini “can pull close up to 200 watts when pushed,” notably higher than Apple Silicon alternatives, and that the fans were audible under that load. His assessment leaned positive for Windows users needing powerful integrated graphics and the flexibility of an x86 platform.
NotebookCheck
According to NotebookCheck, the HP Z2 Mini G1a “convinces as a versatile mini workstation” with their review unit earning a 79% score. The publication praised the sturdy chassis construction, tool-free accessibility, 64GB LPDDR5X ECC memory, dual USB4 (40Gbps) connectivity, and the included 36-month warranty. Their testing confirmed the Radeon 8060S provides workstation-class graphics performance.
The review identified several concerns including the very loud operation under high-performance mode, non-upgradeable memory, elevated DPC latency values, and the lack of a native HDMI port. NotebookCheck concluded that “the HP Z2 Mini G1a is currently one of the best compact workstations on the market: powerful, expandable, and ideal for professional users who are looking for a space-saving solution without compromising on performance.”
StorageReview
StorageReview tested the Z2 Mini G1a’s ability to run massive local AI models without a discrete GPU. Their evaluation highlighted the system’s capability to allocate up to 96GB of VRAM to the integrated graphics for running 120B parameter models locally. They also praised HP’s ZCentral Remote Boost for high-performance remote access scenarios.
The publication noted the system represents “a bold step forward in highly customizable, compact computing” while acknowledging that CPU and GPU configurations cannot be scaled independently and the soldered RAM limits future flexibility. Their hands-on testing with local LLM inference demonstrated practical AI workstation capabilities that would typically require much larger and more expensive systems with discrete GPUs.
A local AI workstation that runs loud
The HP Z2 Mini G1a suits AI developers, content creators, and engineering professionals who need compute power without giving floor space to a tower. The Ryzen AI Max+ PRO silicon paired with up to 128GB of unified memory puts local AI inference and large model development on a machine that sits on the desk beside the monitor. Buyers eyeing the next AMD refresh should read why Gorgon Halo is largely a Strix Halo rename before deciding whether to wait. The metal construction, 36-month warranty, and enterprise management features fit corporate deployments.
Anyone who wants a quiet desk should weigh the 70 dB peak against the room it will sit in. Creative professionals who need a specific discrete GPU, or who plan to add memory later, will do better with a tower. The premium pricing also aims the machine at professional buyers rather than general consumers. Buyers who want solid performance without the workstation price tag should look at the mid-tier Ryzen 7 mini PCs that sit between the budget and premium ends of the market.

Frequently Asked Questions
What processor does the HP Z2 Mini G1a use?
Three chips are offered: the AMD Ryzen AI Max+ PRO 395, the Ryzen AI Max PRO 390, and the Ryzen AI Max PRO 385. The top-tier 395 has 16 Zen 5 cores and 32 threads with boost clocks up to 5.1 GHz. These processors include AMD’s Strix Halo architecture with integrated Radeon 8060S or 8050S graphics and a 50 TOPS neural processing unit for AI workloads.
Can I upgrade the RAM in the HP Z2 Mini G1a?
No. The LPDDR5X memory is soldered and cannot be upgraded after purchase, because the unified memory architecture needs that layout to hit the bandwidth the GPU allocation depends on. Pick the RAM at purchase time: 32GB, 64GB, or 128GB, depending on the variant.
What ports does the HP Z2 Mini G1a have?
The front carries 1x USB-C 10Gbps (with DisplayPort), 1x USB-A 10Gbps, and a combo audio jack. The rear carries 2x USB4 Type-C 40Gbps (Thunderbolt 4 compatible), 2x Mini DisplayPort 2.1, 2x USB-A 10Gbps, 2x USB-A 2.0, and 2.5 Gigabit Ethernet. Two Flex IO slots can add HDMI, VGA, serial, or additional USB ports.
What’s included in the box with the HP Z2 Mini G1a?
The box holds the unit itself, which has its 300W power supply inside the chassis, and a power cord. Some configurations add an HP wired keyboard and mouse, and some add a DisplayPort to Mini DisplayPort adapter.
How much GPU memory does the HP Z2 Mini G1a have?
There is no separate pool. AMD’s unified memory architecture has the Radeon 8060S or 8050S graphics share system memory with the CPU. On the 128GB configuration, up to 96GB can be allocated to the GPU for AI workloads and large language model inference that would otherwise need expensive discrete GPUs with dedicated VRAM.
How loud is the HP Z2 Mini G1a?
Fan noise measured up to 70 dB during sustained workstation tasks. Idle and light usage stay much quieter, but fan speed climbs sharply once a demanding application loads the chip. Workstation-class silicon in a 6.61 by 7.87 inch chassis has to move that heat somewhere.
Does the HP Z2 Mini G1a support VESA mounting?
Yes. VESA mounting attaches it to the back of a compatible monitor for a clean desk setup. HP also notes the chassis is designed to fit five units across a 4U rack for data center or high-density workstation deployments.
