The GIGABYTE B850 AI Top DDR5 is an ATX-form-factor motherboard (30.5 cm x 24.4 cm) built on the AMD B850 chipset with Socket AM5, supporting AMD Ryzen 9000, 8000, and 7000 Series processors. It is designed for enthusiast builders, content creators, and users looking to run local AI workloads at the desktop level. Memory support is extensive: four DDR5 DIMM slots in a dual-channel configuration accept up to 256 GB of system memory (64 GB per DIMM), with speeds reaching DDR5-8600 MT/s via overclocking. The board supports AMD EXPO and XMP profiles, as well as ECC and non-ECC unbuffered DIMMs. Storage options are strong. Three M.2 Socket 3 connectors are provided — two CPU-direct slots (M2A_CPU and M2B_CPU) that support PCIe 5.0 x4 SSDs with Ryzen 9000/7000 processors, and one chipset slot (M2C_SB) running PCIe 4.0 x2. Four SATA 6 Gb/s ports are also present. RAID 0, 1, 5, and 10 are supported for NVMe devices (RAID 5 requires Ryzen 9000); RAID 0, 1, and 10 apply to SATA. Expansion slots include a primary PCIe 5.0 x16 slot and a second PCIe 5.0 x8 slot (both CPU-integrated for Ryzen 9000/7000), plus a chipset PCIe 4.0 x2 slot. The VRM is a 16+2+2 phase Digital Twin design with a one-piece VRM heatsink featuring a heatpipe and 5 W/mK thermal pads. Networking is a standout: two Marvell AQtion AQC113C chips deliver dual 10 GbE LAN (supporting 10/5/2.5/1 Gbps and 100 Mbps), complemented by a Realtek Wi-Fi 7 RTL8922AE module supporting 802.11be with 2.4/5/6 GHz bands, 160 MHz channels, and Bluetooth 5.4. Rear I/O includes HDMI 2.1 (up to 4096×2160@60 Hz), a USB Type-C port with DisplayPort 1.4 and USB 3.2 Gen 2 support, three USB 3.2 Gen 2 Type-A ports, four USB 3.2 Gen 1 ports, four USB 2.0 ports, two RJ-45 ports, optical S/PDIF out, and two audio jacks. An internal USB Type-C header supports USB 3.2 Gen 2×2 (20 Gb/s). Fan control covers up to 24 W (12 V x 2 A) per header with PWM/DC and pump support. Audio is handled by a Realtek ALC1220 codec with High Definition Audio supporting up to 7.1-channel output and DSD playback on the rear line-out. BIOS uses a licensed AMI UEFI with Q-Flash, Q-Flash Plus, and Smart Backup support. RGB headers include three addressable Gen2 ARGB and one standard RGB strip connector.
