With prices on AMD's Ryzen 5950X 16-core Zen 3 based processor slowly coming back into the realms of MSRP, ASUS is taking advantage of recent events by announcing its latest flagship X570 motherboard, the ASUS ROG Crosshair VIII Extreme. Overtaking the current ASUS ROG Crosshair VIII Dark Hero as the premier motherboard in the ROG series, the Extreme includes a 20-phase power delivery, dual Thunderbolt 4-capable USB Type-C ports, 10 Gb Ethernet, and support for up to five PCIe 4.0 M.2 drives.

In what looks like one of ASUS's last motherboard unveilings for AMD's X570 platform, the ROG Crosshair VIII Extreme is ultimately its most feature-packed Ryzen desktop motherboard so far. While ASUS at the time of writing hasn't unveiled a full list of the specifications, we know many of the board's core features, giving the EATX-sized board an impressive résumé. At the heart of the ROG Crosshair VIII Extreme are dual full-length PCIe 4.0 slots that operate in either x16/x0 or x8/x8 when paired with a Ryzen 5000 or 3000 desktop processor. ASUS also includes a small PCIe 3.0 x1 slot for one more peripheral.

The ROG Crosshair VIII Extreme design for X570 follows a black glossy aesthetic, with multiple areas of integrated RGB LED lighting, including along the rear panel cover, chipset heatsink, and even part of the underside of the board. Along with other X570/X570S motherboards recently announced, the Crosshair VIII Extreme will feature a passively cooled chipset.

For storage, ASUS includes three onboard PCIe 4.0 x4 M.2 slots, with room to add a further two PCIe 4.0 x4 slots via an included DIMM.2 slot located to the right of four memory slots. There are six SATA ports for conventional SATA devices with support for RAID 0, 1, and 10 arrays. The ROG Crosshair VIII Extreme will support up to DDR4-5000 memory with a maximum capacity of up to 128 GB of DDR4 across four memory slots.

Other features include an Intel Thunderbolt 4 controller that's driving a pair of USB Type-C ports, a Marvel AQC1113CS 10 Gb Ethernet controller, and a second Intel I225-V 2.5 GbE controller. On top of this, there's Intel's latest AX210 Wi-Fi 6E wireless interface, which also supports the latest BT 5.2 devices. Onboard audio is also quite premium, spearheaded by a ROG SupremeFX ALC4082 HD audio codec and is assisted by an ESS Sabre 9018Q2C DAC. 

With 'Extreme' being this model's moniker and focus, the ASUS ROG Crosshair VIII uses a 20-phase power delivery (18+2) with premium 90 A power stages and is likely to be arranged in teamed mode, which is a common theme in its power design across the series. This also includes an LN2 mode dip switch designed for enthusiasts looking to use aggressive sub-zero cooling methods such as liquid nitrogen (LN2) or dry ice (DICE) for the maximum benchmark performance.

At the time of writing, ASUS hasn't announced when the ROG Crosshair VIII Extreme will be available to purchase or how much it will cost.

    It's odd, x570 offers trading two sets of x4 lanes for two x4 sata... I'm sure they burned those x4 lanes on an extra m.2 slot, but how did they end up at x6 sata?

    I believe you get 2 SATA ports natively on Ryzen. So 2 CPU + 4 chipset = 6

    I wonder if this is like the ROG STRIX X570-E where the big plastic shroud sticks up so high that some graphics cards won't fully seat in the PCIe slot.

    It looks as if at least one PCI-Express x16 slot's shroud is removable.
    Still, blocking card installation clearly indicates a design error on someone's part.

    If it came out sooner, I would of purchased it. It is coming later towards the end of the AM4 life, but that looks to be the most complete motherboard yet and has everything integrated and on the backplate including 2 Thunderbolt 4 USB C ports and 2 DisplayPorts. Currently I have the Gigabyte Aorus X570 Xtreme v1.1 Motherboard with Thunderbolt 3 header and the Titan Ridge add-on card and hard to justify upgrading the board at this time, but if price looks good, it could be tempting, if I plan any major upgrades.
