Best AM4 motherboards in 2026
This ranking is computed, not curated. Each of the 3 AM4 boards in the database is run against all 28 AM4 processors, and the ranking is the count of processors the board keeps under our moderate-throttling threshold. A board that handles everything sits at the top whatever it costs, which is why a mid-range board sometimes beats a flagship.

Full ranking
“Handles” counts the processors this board runs with no expected clock loss. “Throttles” counts the ones it cannot feed.
How this ranking is produced
Every board is evaluated against every processor on its socket using the same formula: Vcore stages multiplied by their current rating and by an effective Vcore of 1.25 V, derated for the phase design and for heatsink mass, then compared against each processor's sustained package power. Sample size is 3 boards × 28 processors = 84 evaluations, of which 2 boards have a verified retail listing.
The constants and the formula are published in full, so you can disagree with a specific number rather than with a verdict.
