The HP Z2 Tower G1i Workstation is a professional desktop computer for demanding work environments, designed based on an Intel Core Ultra 9 processor and a dedicated NVIDIA RTX PRO 4000 Blackwell graphics card. The system is designed for use in workflows with high requirements for computing power, graphics processing, and AI-accelerated tasks. It features 64 GB DDR5-SDRAM memory and a 1 TB SSD storage drive, operated via the PCI Express 5.0 interface with NVMe technology. The workstation is configured as a tower housing and includes a 700 W power supply.

Applications

The HP Z2 Tower G1i is suitable for professional applications such as 3D modeling, simulation, rendering, CAD, CAM, video editing, as well as AI-based development and inference processes. The combination of a powerful processor, dedicated graphics, and integrated NPU enables efficient processing of complex tasks. Support for Wi-Fi 7 (802.11be) and Bluetooth 5.4 ensures modern network connections, while the integrated Intel graphics serves as a backup for basic display tasks.

Features and Specifications in Detail

The Intel Core Ultra 9 285K processor features 24 cores, with 8 performance cores and 16 efficient cores distributing the workload according to the task load. The maximum turbo frequency reaches 5.7 GHz, with performance cores up to 5.5 GHz and efficient cores up to 4.6 GHz. The processor includes a 36 MB L3 cache and a base power of 125 W, which can increase up to 250 W turbo power when needed. The integrated Neural Processing Unit (NPU), known as Intel AI Boost, supports AI software frameworks such as DirectML, OpenVINO, Windows ML, ONNX RT, and WebNN. The total performance of the processor reaches up to 36 tera-operations per second, with the NPU contributing up to 13 tera-operations per second and the GPU up to 8 tera-operations per second.

Technology Explained Simply

The memory architecture consists of two 32 GB DIMM modules in UDIMM format with a clock speed of 5600 MHz (5600 MT/s), ensuring fast data transfer. The M.2 form factor SSD storage uses the fast PCI Express 5.0 interface and is configured as an NVMe drive, providing short access times and high data throughput. The dedicated NVIDIA RTX PRO 4000 Blackwell graphics card features 24 GB GDDR7 memory and is optimized for professional graphics applications. The integrated Intel graphics serves as a backup and enables system operation even without the dedicated GPU.

Compatibility and Accessories

The system supports operation under Windows 11 Pro for Business, with WSL2 or Linux® operating systems also possible. Network connectivity includes Wi-Fi 7 (802.11be) via the Intel Wi-Fi 7 BE200 controller with 2x2 antenna configuration, as well as Bluetooth 5.4. The interfaces include 3 USB 2.0, 6 USB 3.2 Gen 2 (Type A), 2 USB 3.2 Gen 2x2 (Type C), 2 DisplayPort 1.4, 1 Ethernet LAN (RJ-45), and a combined headphone/microphone jack. For expansion, there is 1x 8,9 cm ( 3,5 inch ) expansion slot and 1x PCI Express x16 slot (Gen 4.x) available.

Installation and Mounting

The HP Z2 Tower G1i is designed for tool-free access, simplifying upgrades of components such as memory, SSDs, or graphics cards. The intelligent fan control adjusts fan speeds in real time according to load, and the ventilation opening with a grid design optimizes airflow. The housing is suitable for rack environments, with a 4-HE rack accommodating one unit.

Operational Advantages

The workstation offers high expandability and maintainability, making it suitable for changing requirements. The combination of a powerful CPU, dedicated GPU, and integrated NPU enables efficient processing of AI and graphics applications. The use of recycled plastic (60 %) and steel (20 %), along with sustainably sourced outer packaging, meets the sustainability standards of EPEAT® Gold with Climate+.

Product Type, Core Function, Technology, Standard

The device is classified as a workstation, primarily designed for AI-accelerated workflows and professional graphics applications. The technology includes Intel Core Ultra 9, NVIDIA RTX PRO 4000 Blackwell, and Intel AI Boost. The standard Wi-Fi 7 (802.11be) ensures a modern, high-performance WLAN connection.
