GIGABYTE Z890 AI TOP Intel motherboard

LGA 1851 platform for Intel Core Ultra Series 2

This E-ATX motherboard uses the Intel Z890 chipset and the LGA 1851 socket to support Intel Core Ultra processors from Series 2. Four DDR5 DIMM slots accept up to 256 GB of memory with XMP 3.0 profiles. Dual Thunderbolt 5 ports, Wi-Fi 7 and twin 10 GbE LAN ports handle high-throughput peripherals and networking. The board targets workstation builds that need maximum connectivity and expandability.

Sustained-load behaviour and thermal design

A 16+1+2 phase power delivery uses 80 A smart power stages to feed the CPU during long render or compile sessions. VRM Thermal Armor Advanced and M.2 Thermal Guard dissipate heat across the voltage regulators and four M.2 slots. This cooling layout keeps clock speeds stable when all cores run at high frequency for extended periods.

PCIe 5.0 and Thunderbolt 5 interface limits

The primary PCIe 5.0 x16 slot runs at x16; a second CPU-linked x16 slot runs at x8 and shares bandwidth with the first. A chipset-linked PCIe 4.0 x4 slot becomes unavailable when the corresponding M.2 connector is populated. Thunderbolt 5 provides up to 80 Gbps of bidirectional bandwidth for external storage and display chains.
