Product Features
Technical Overview
At the core of the Z4 G5 is the Intel Xeon W w5-2465X processor, a hexadeca-core CPU operating at 3.10 GHz on the Socket LGA-4677 platform. This processor is paired with the Intel W790 chipset, providing a stable foundation for workstation-class workloads and supporting advanced features like AI acceleration. The memory subsystem utilizes 64 GB of DDR5 SDRAM configured across four 16 GB modules running at 4.80 GHz, with ECC and Registered signal processing to maintain data integrity under heavy loads.
Storage performance is driven by a 512 GB PCI Express NVMe 4.0 x4 solid-state drive, offering exceptional read/write speeds for operating systems, applications, and project files. The system supports RAID configurations (0, 1, 5, 10) via Serial ATA/600 and NVMe controllers, enabling data redundancy or performance optimization based on user requirements. Graphics output is handled by a dedicated 4 GB card with 80 GB/s memory bandwidth, sufficient for professional 2D/3D applications and multi-monitor setups through three Mini DisplayPort connectors.
