Gigabyte W775-V10-L01 deskside system validated at 2.2B tokens/day on NVIDIA GB300 (Blackwell Ultra GPU), achieving 800 Gbps throughput via ConnectX-8 SuperNIC.
The Gigabyte W775-V10-L01 is an NVIDIA DGX Station GB300-based system designed for deskside deployment. While the concept is straightforward, the execution is sophisticated. The system features liquid cooling and operates within a 1.6kW maximum power envelope, allowing it to run on standard 120V circuits. Performance is exceptional: we achieved over 26,000 tokens per second with Qwen 3.6-35B-A3B Flash NVFP4, translating to over 2.2B tokens per day from this practical large language model. We tested the ConnectX-8 400Gbps RDMA networking and the high-speed Chiplet-to-Chiplet (C2C) link between the NVIDIA Grace 72-core CPU and NVIDIA Blackwell Ultra (B300) GPU—and found compelling results across the board.

The W775 consolidates the full hardware stack of a GB300 server into a desktop form factor. This is not merely a Grace CPU paired with a server-grade, HBM3E-equipped Blackwell Ultra GPU, nor simply high-end dual 400Gbps networking. It combines all critical components of the GB300 ecosystem, delivering the complete and unrestrained Grace Blackwell experience rather than a constrained slice like GB10-based systems.

## External Hardware Overview
The W775 houses substantial silicon and an extensive liquid cooling system within a full-size tower case measuring 500mm tall and 530mm deep. The system weighs approximately 29kg (64 lbs)—substantial enough that Gigabyte recommends two-person handling and specifies proper grip points to avoid stressing the plastic front panel, which cannot support the full weight.
Despite its premium price point (a hundred-thousand-dollar workstation), the W775 presents an unassuming aesthetic. The case itself is a fairly typical PC chassis with minimal customization—one of the few design liberties OEMs have within the DGX Station specification. We have not identified other Gigabyte systems using this particular case design.
The W775's front panel is purely decorative, serving no cooling function. Gigabyte routes all airflow through the remaining case sides as intake or exhaust, which aids acoustics by eliminating forward-facing fan noise. The left side features a vent covering intake fans, while the right side exposes the radiator with three exhaust fans. Consequently, all I/O and controls are positioned on the top panel, reflecting the system's intended placement on the floor rather than a desk.
The top panel I/O is minimalist: two 5Gbps USB-A ports, one 10Gbps USB-C port, and discrete 3.5mm headphone and microphone jacks. Higher-speed transfers (above 10Gbps) route through the dual 400Gb QSFP112 ports via the integrated ConnectX-8 SuperNIC. Notably, Gigabyte omitted USB-IF branding and used non-blue connectors on the USB-A ports, leaving no visual indication of their 3.x-speed capability.
The rear follows ATX conventions with fan mount, I/O bracket, expansion slots, and PSU layout. Gigabyte selected a 120mm Sunon fan for rear exhaust. Networking dominates the rear I/O: four Ethernet ports routed through three controllers. The two QSFP112 ports connect to NVIDIA's ConnectX-8 SuperNIC, each delivering 400Gbps—the primary interface for high-speed storage and inter-DGX networking. These ports support both direct-attach copper (DAC) cables and optics; we found NVIDIA's MMS1X00-N5400 optics (approximately 10W) performed well given limited airflow around the optical cages.
Two RJ45 jacks provide conventional networking: the left port (labeled 'M') connects to the OpenBMC management controller with HTML5 iKVM functionality; the right port is a 10Gb Ethernet link powered by Marvell's AQC-113C controller, which connects through the ConnectX-8 rather than directly to the CPU—an arrangement reflecting the system's complex topology.
The four rear USB-A ports operate at 10Gbps, matching the USB-C port on the top panel.
