The most fundamental difference between these two Mini-ITX boards lies in their platform allegiance: the ROG Strix B850-I targets AMD's AM5 ecosystem with a B850 chipset, while the B860-I is built for Intel's LGA 1851 platform with a B860 chipset. This means they are not interchangeable — your CPU choice dictates which board is relevant to you. Neither platform is objectively superior based on the data here; this is purely an AMD-vs-Intel decision.

Where the two boards converge is striking: both share an identical 170 × 170 mm Mini-ITX footprint, Wi-Fi 7 (backwards compatible through Wi-Fi 4), Bluetooth 5.4, HDMI 2.1, RGB lighting, dual BIOS, easy BIOS reset, and a 3-year warranty. Both also support overclocking despite using mid-range chipsets, which is a meaningful feature for enthusiasts building compact, high-performance systems. Neither board includes integrated graphics or an integrated CPU.

In terms of general features, these boards are essentially mirror images of each other across different CPU platforms. There is no advantage for either product within this spec group — the winner here is determined entirely by which CPU socket you need: AM5 for the B850-I or LGA 1851 for the B860-I.

The Asus ROG Strix B850-I Gaming WiFi and the Asus ROG Strix B860-I Gaming WiFi have a few differences in their connector configurations. Both motherboards provide 2 USB 3.2 Gen 1 ports and 2 USB 2.0 ports through expansion, and 2 USB 3.0 ports through expansion. In terms of storage connectivity, the B850-I offers 2 SATA 3 connectors, while the B860-I has 4 SATA 3 connectors, providing more storage options on the B860-I.

Another key difference is in the fan headers. The B850-I has 6 fan headers, which is more than the 2 fan headers available on the B860-I. This could make the B850-I a better option for users needing more cooling options for their system. The B860-I, however, has a TPM (Trusted Platform Module) connector, which is not available on the B850-I. The presence of the TPM connector on the B860-I can be useful for users requiring enhanced security features.

Both motherboards feature 2 M.2 sockets, and neither supports U.2 or mSATA connectors. Additionally, neither has SATA 2 connectors. The differences in the number of SATA 3 connectors, fan headers, and the inclusion of the TPM connector are the primary distinctions between the two products in this category.

Expansion slots:
