GIGABYTE B850 AI TOP AM5 ATX Motherboard

Description

Overview

The GIGABYTE B850 AI TOP is an ATX motherboard for AMD’s AM5 platform, engineered for demanding desktop builds that need high memory bandwidth, fast NVMe storage and top‑tier networking. It is positioned for gamers, creators and users running heavy local workloads (including AI inference) who want PCIe 5.0 storage, dual 10Gb Ethernet and Wi‑Fi 7 built in.

Key features

• Socket & chipset: AMD Socket AM5 with B850 chipset; supports AMD Ryzen 7000, 8000 and 9000 series processors (check Gigabyte CPU support list and BIOS requirements).
• Memory: 4 × DDR5 DIMM sockets, up to 256 GB total; DDR5 OC support up to 8600 MT/s (OC).
• Storage: 3 × M.2 slots (two CPU‑linked M.2 supporting PCIe 5.0 x4 with compatible CPUs; one chipset M.2 PCIe 4.0 x2), plus SATA 6Gb/s ports.
• Expansion & PCIe: Full‑length PCIe x16 slot(s) wired to CPU (PCIe 5.0 where supported); lane sharing applies when multiple M.2/PCIe devices are populated—refer to manual.
• Networking: Dual 10 Gigabit Ethernet (Marvell AQC113C) and Realtek Wi‑Fi 7 (RTL8922AE) with high‑gain antenna and Bluetooth support.
• Power & cooling: 16+2+2 digital VRM design for robust CPU power delivery and extended heatsinks on VRM and M.2 areas.
• Connectivity: Rear USB‑C up to 40 Gbps, front USB‑C header (up to 20 Gbps), multiple USB 3.x and USB 2.0 ports, onboard power/reset and Q‑Flash/BIOS convenience features.

Notes

• Some features (PCIe 5.0 for M.2 or GPU) depend on the installed CPU and BIOS version — always check Gigabyte’s CPU support list and install the recommended BIOS for newer Ryzen processors.
• When using multiple M.2 devices the board may reduce PCIe lanes available to the primary GPU slot; consult the manual for exact lane sharing behaviour.
