Both models feature Intel networking and Realte ALC1220 audio. The Tomahawk lacks a Realtek network, but the Gaming Pro Carbon offers superior sound quality. The Tomahawk Max can run the 3600 model without needing a BIOS flash.

Gaming Pro Carbon AC offers superior audio, network performance, and wireless capabilities. Tomohawk Max provides marginally better BIOS and VRM heatsink—though this detail is mostly irrelevant. I’d choose the Carbon AC if the cost matches. Both boards allow BIOS flashback; simply insert the USB stick, connect it without the CPU in the socket, press the back-side IO shield button, and within a minute the BIOS updates.
