Both boards share the same AM5 socket and B850 chipset foundation, meaning identical CPU compatibility and a similar overclocking ceiling. They also mirror each other on several quality-of-life features: dual BIOS for recovery safety, RGB lighting, HDMI 2.1 output, and a 3-year warranty. For most builders, these shared traits make the platform experience feel very comparable out of the box.
The most consequential difference in this group is the form factor. The ASRock B850M Steel Legend WiFi is a Micro-ATX board at 244×244 mm, while the Gigabyte B850 Gaming X WiFi6E is a full ATX board at 244×305 mm. This is a build-defining choice: the ASRock fits in smaller, more compact cases and reduces overall system footprint, whereas the Gigabyte's larger PCB typically allows for more expansion slots, better component spacing, and easier cable management in mid-tower builds. Neither is objectively superior — it depends entirely on the chassis and use case.
On wireless connectivity, the ASRock holds a clear edge: it supports Wi-Fi 7 (802.11be), the latest standard offering significantly higher theoretical throughput and lower latency than Wi-Fi 6E, while the Gigabyte tops out at Wi-Fi 6E. The ASRock also edges ahead with Bluetooth 5.4 versus the Gigabyte's 5.3, a minor but forward-looking advantage. For users who rely heavily on wireless peripherals or fast home networking, the ASRock's wireless stack is the more future-proof of the two.
