GIGABYTE Launches B850 Desktop for Local AI Inference and Fine-Tuning

On September 30, 2026, GIGABYTE announced the AI TOP 100 B850, a workstation-class desktop system designed for local AI workloads. The machine is built around an AMD Ryzen 9 9950X processor with a 240mm AIO cooler and an AMD B850 motherboard, featuring 128GB DDR5 memory, a 2TB SSD, and two PCIe Gen5 slots.

Users can configure the system with either a single NVIDIA GeForce RTX 5090 or two AMD Radeon AI PRO R9700 graphics cards. The chassis includes a 1600W 80 PLUS Platinum power supply, dual 140mm front fans and a rear 140mm fan for front-to-back airflow. The motherboard uses a 16+2+2 phase power design and offers two 10GbE RJ-45 ports, Wi-Fi 7, and a front USB-C 20Gbps port.

According to GIGABYTE, the RTX 5090 single-GPU configuration delivers 64.9 tokens per second on a 32B model, while the dual R9700 configuration supports inference on 235B models and fine-tuning of 110B models.
