The HP Z2 Tower G1i Workstation is a professional workstation designed for demanding workflows in technical, creative, and engineering fields. It features an Intel Core Ultra 9 processor from the 285K series, with 24 cores and 24 threads, providing high parallel processing capacity. The processor performance is supported by intelligent fan control that adjusts fan speeds in real time to efficiently dissipate heat. Cooling is further optimized by a new ventilation opening in a grille design, improving airflow. The workstation is suitable for use in rack environments and fits into a 4-HE rack, allowing flexible integration into existing infrastructures.

Applications

The HP Z2 Tower G1i is suitable for professional applications requiring high computing power and memory bandwidth, such as 3D modeling, simulation, rendering, CAD/CAE development, and AI-accelerated workflows. Support for high-end graphics cards enables the use of up to 600 W, triple-wide graphics cards, which is critical for demanding graphical applications. The integrated NPU (Neural Processing Unit) supports AI-based tasks such as inferencing and development, with the NPU capable of up to 13 tera-operations per second. GPU performance reaches up to 8 tera-operations per second, enhancing efficiency in AI and graphics applications.

Features and Specifications in Detail

The workstation is equipped with 64 GB DDR5-SDRAM, distributed across two modules of 32 GB each, with a clock frequency of 5600 MHz. This memory configuration ensures a high data transfer rate of 5600 MT/s and supports demanding applications requiring high bandwidth. The internal storage consists of a 2 TB SSD in M.2 form factor with PCI Express 5.0 interface and NVMe support, providing fast read and write speeds. The SSD is installed as the sole storage drive, ensuring fast system response and short application and file loading times.

Technology Explained Simply

The Intel Core Ultra 9 285K processor features 8 performance cores and 16 efficient cores, with the performance cores reaching up to 5.5 GHz and the efficient cores up to 4.6 GHz turbo frequency. The base frequency is 3.7 GHz (performance cores) and 3.2 GHz (efficient cores). The total performance of the processor reaches up to 36 tera-operations per second, with the NPU contributing a significant portion of this performance for AI tasks. The integrated Intel graphics support basic graphical applications, while the workstation is designed for installation of a separate, high-performance graphics card. The power supply has a capacity of 700 W and supports input voltages from 100 to 240 V.

Compatibility and Accessories

The workstation supports Wi-Fi 7 (802.11be) with an Intel Wi-Fi 7 BE200 controller and Bluetooth 5.4, enabling fast and stable wireless connections. The network interface includes an RJ-45 port with 10/100/1000Base-T(X), providing a fixed LAN connection. I/O options include 3 USB 2.0 ports, 6 USB 3.2 Gen 2 (Type A), and 2 USB 3.2 Gen 2x2 (Type C), as well as 2 DisplayPort connections (version 1.4). Additionally, line-out, line-in, and a combined headphone/microphone jack are available. Expandability is supported by a 8,9 cm ( 3,5 inch ) expansion slot and a PCI Express x16 slot (Gen 4.x), allowing installation of additional PCIe cards.

Installation and Mounting

The HP Z2 Tower G1i is designed for tool-free access, simplifying upgrades of components such as memory, SSD, or graphics cards. The construction allows easy expansion of system resources without requiring special tools. The workstation is housed in a tower enclosure and can be operated either on a desk or in a rack.

Operational Advantages

The combination of a powerful processor, fast DDR5 memory, and NVMe SSD ensures high system responsiveness and short loading times. The integrated NPU efficiently supports AI-based applications, increasing productivity in AI workflows. Support for high-end graphics cards enables the use of powerful GPUs for demanding graphical applications. Sustainability is emphasized through the use of 60% recycled plastic and 20% recycled steel in the enclosure, as well as EPEAT® Gold with Climate+-certification. The operating system is Windows 11 Pro for Business, facilitating integration into existing enterprise environments.
