Which CPUs fit this board?

It uses Intel's LGA-1851 socket, so it takes Core Ultra 200-series desktop processors. Older LGA-1700 chips will not fit.

Is USB4 the same as Thunderbolt 4?

No. This board's USB4 port runs at 20Gbps, while Thunderbolt 4 and 5 reach 40Gbps and beyond. It still handles docks and fast SSDs, just at lower peak speed.

Does it take DDR4 memory?

No, it is DDR5 only. Plan on a new DDR5 kit rather than reusing DDR4 from an older build.

How does it compare with the Asus TUF Gaming Z890-Plus?

Both are mid-range ATX Z890 boards. The Aorus Elite Duo X leans on USB4 and Wi-Fi 7, while the TUF line emphasizes durability and a simpler feature set.

What comes in the box?

Expect the board, SATA cables, a Wi-Fi antenna and mounting hardware. Check the specific bundle before buying if you need extra cables.

Is it worth it over a cheaper Z890 board?

If you need USB4 and Wi-Fi 7 built in, yes. If you use wired networking and standard USB, a lower-tier Z890 board covers the same CPU and PCIe 5.0 support.
