The most fundamental difference between these two boards is their CPU platform: the ASRock B860M LiveMixer WiFi uses an LGA 1851 socket with the Intel B860 chipset, targeting Intel's latest Core Ultra 200 series processors, while the MSI MPG B850 Edge Ti WiFi uses an AM5 socket with the AMD B850 chipset, designed for AMD Ryzen 7000/9000 series CPUs. This means the two boards are not interchangeable — your CPU choice dictates which board is relevant to you, and vice versa.
On form factor, the ASRock is a Micro-ATX board (244 × 244 mm), making it a better fit for compact or mid-tower builds with space constraints, while the MSI is a full ATX board (304.8 mm wide), offering more physical space for additional slots, headers, and cooling options. For wireless connectivity, both support up to Wi-Fi 6E, but the MSI adds Wi-Fi 7 (802.11be) support, which delivers significantly higher throughput and lower latency on compatible routers — a tangible advantage for users on cutting-edge networking hardware. The MSI also edges ahead on Bluetooth 5.4 versus the ASRock's Bluetooth 5.3, though the real-world difference here is minimal. One notable tradeoff: the ASRock includes a dual BIOS feature for firmware recovery redundancy, while the MSI lacks this but offers an easy BIOS reset mechanism — the ASRock does not.
Both boards share the same 3-year warranty, HDMI 2.1 output, RGB lighting, and overclocking-friendly flagging. Neither integrates a CPU or onboard graphics. Overall, the MSI MPG B850 Edge Ti WiFi holds a general-info edge thanks to its Wi-Fi 7 support, larger ATX footprint for expandability, and newer Bluetooth — but the ASRock's dual BIOS is a meaningful reliability perk for users who frequently update firmware or want a safety net against failed flashes.
