The mainstream B850 value king
MAG B850 Tomahawk Max WiFi
The Tomahawk Max WiFi: 80A SPS VRM, Gen5 GPU and M.2, Wi-Fi 7 and 5G LAN at ~$210 - the price the newer Max II is judged against.
Our verdict
The Tomahawk Max is the B850 board reviewers keep pointing back to: when Tom's Hardware and TweakTown reviewed the newer Max WiFi II, both concluded this board at ~$210 is the value the II has to justify itself against - and at a $50 gap it mostly cannot. Buy the II for the OC Engine and 64MB BIOS; buy this one for the build.
Best for: The mainstream AM5 gaming build - the sane default in the Tomahawk family.
Skip it if: You want BCLK overclocking or the biggest BIOS headroom - that is what the Max II sells.

What reviewers say
Tom's Hardware
Reviewing the successor Max WiFi II (4/5): the II's $269.99 price 'is more than the others, but if you use the features, it's worth it over the Max or original B850 Tomahawk' - the inverse being Tom's point that if you skip BCLK overclocking and the 64MB BIOS, this cheaper Max is the smarter buy.
Full review ↗TweakTown
In their Max WiFi II review (86%), TweakTown withheld an award from the newer board specifically because 'discounted Tomahawk Max I boards undercut its $269 MSRP' - naming this board the value pick of the family.
