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.

    Hopefully it will not be another ~$1000 MB. Reply

    I suspect it will be over $600. Reply

    Only 2 x full length PCIe slots on a $1000000000 Extreme XXX Super duper 80 + 74 phase VRM motherboard?? Reply

    Looks really nice. I just wish they would put more than 8 USB-A ports on the rear panel. The Aurous Xtreme still wins in my book because it has 11 USB-A ports on the rear panel.

    Also these photos aren't very high resolution, so I can't properly make it out, but do those DisplayPort ports say "DP IN"? I've never heard of a motherboard with a built-in capture card but that'd add a lot of value.

    Also there is no mention of ECC support but I would consider that a starter for a motherboard in this category. Reply

    "DP in" is for outputting video through the thunderbolt ports.
    There are a few other thunderbolt capable mobos that have this same feature.

    I still haven't seen many thunderbolt displays. Are there any VR HMDs that run off thunderbolt? Reply
  • evilspoons - Tuesday, August 3, 2021 - link

    Yeah it's not actually video capture, it's more like it'll take the DP signal from an external GPU and combine it into the Thunderbolt stream, allowing you to use a Thunderbolt dock or whatever with the video signal on a single cable. Reply

    They should have put 8xSATA Ports on this all in one board esp when this one has more lane throughput than a Z590. Even their own C8DH has 8x. Maybe those Thunderbolt ports take up the bandwidth.

    Also the only aspect that I'm waiting to hear is does X570S share same issues as X570 for USB and USAP or not & I'm not going to spend $1000 on a Mobo. That's way too much, for a non HEDT platform.

    The price of a system comes in around the same as a TR Pro/WRX80 system but you get the most cores while getting the single threaded crown. Reply
