X870 motherboards
X870 is the single-die version of AMD's 800-series flagship: USB4 and PCIe 5.0 graphics are still mandatory, with fewer downstream lanes than X870E.

- The thing people get wrong
- The practical difference from a good B850 board is port count rather than performance, and both ship with firmware that already knows every Zen 5 processor.
The spread inside X870
Inside this one chipset, the Gigabyte X870 Aorus Elite WiFi7 holds about 1080 W of sustained core power and the MSI MAG X870 Tomahawk WiFi holds about 1260 W. That is a factor of 1.2 between two boards wearing the same badge, and it is the reason a chipset name is a poor proxy for whether your processor will keep its clocks.
The same processors on the best and worst X870 board
Sorted worst verdict first, so the pairings to avoid are at the top.
