Gigabyte Z890I AORUS Ultra (LGA1851/Intel Z890/Mini-ITX/VRM Not Officially Disclosed/Thunderbolt 4) Review
The Z890I AORUS Ultra brings Gigabyte's AORUS branding to the Intel Core Ultra 200S Mini-ITX segment, combining CUDIMM-ready DDR5 support with Thunderbolt 4 connectivity for compact high-performance Intel builds.
Gigabyte does not officially disclose an exact phase count or amperage for this board's VRM; the cooling solution and layout suggest a mainstream-tier design suited to Core Ultra 7/9 chips at stock-to-moderate settings rather than extreme overclocking. Two DDR5 DIMM slots support up to 128GB total capacity, with CUDIMM support enabling speeds up to 9200 MT/s and beyond on supported Core Ultra 200S processors. A single PCIe 5.0 x16 slot handles the GPU, with two M.2 slots split between a PCIe 5.0 x4/x2 CPU-connected slot and a PCIe 4.0 x4/x2 chipset-connected slot. A 2.5GbE Realtek LAN controller pairs with Wi-Fi 7 via an Intel BE202 module and Bluetooth 5.4. Thunderbolt 4 support delivers 40Gbps connectivity for external storage or displays, and Q-Flash Plus enables BIOS updates without an installed CPU. Compared to the ASUS ROG Strix Z890-I Gaming WiFi in this catalog, the Z890I AORUS Ultra offers a single Thunderbolt 4 port versus ASUS's dual-port implementation, positioning it as a slightly more value-focused Z890 ITX option.
