Writing this review, I'm already conflicted on which X570 motherboard is the best. I say that because I have waiting in the wings, the X570 Dark from EVGA, and as it finishes testing, it's looking to be a pretty solid platform in its own right. The Crosshair Extreme has a legacy. It's been the AMD go-to platform for years, and ASUS shows us why with an all-out motherboard that brings everything to the table with tons of connectivity and a downright nasty power setup for those wanting to push the limits of overclocking.

Like the Dark Hero, the Extreme is built on the X570S chipset; the internet will tell you its X570 built on a more refined process to be cooler and use less power; I have a message in with my contact at AMD to find out for sure, we should know before I write up the EVGA article later this week.

At the top of the list, the Extreme is compatible with all Ryzen CPUs back to the 2000 series. It supports 128GB of DDR4 memory with varying speed ratings depending on what generation your CPU is. For Ryzen 5000, we have support from 2133MHz to 5000MHz.

Down the line, we have two Thunderbolt 4 ports that support DP 1.4 and Thunderbolt video out. Additionally, there are five m.2 slots and six SATA ports, and for networking, we have both Intel i225 2.5Gbe and Marvell 10Gbe. Wi-Fi 6e is added via the AX211 chipset from Intel, and this also includes Bluetooth 5.2.

Audio is SupremeFX 7.1 with the ALC4082 chipset; this also includes the SABRE9018 DAC.

Pricing

The ROG Crosshair VIII Extreme carries an MSRP of $799.99 with a three-year warranty.

The Crosshair Extreme is our first board to be tested with Windows 11. We run the latest beta build in testing to minimize the chance of bugs. It's also our first to go through our new testing regiment that includes starts with storage.

ASUS ROG Crosshair VIII Extreme Motherboard Review 40 | TweakTown.com

We begin with SATA performance testing with our WD Blue 1TB. This drive gave us 552 MB/s reads and 473 MB/s write on the Extreme.

ASUS ROG Crosshair VIII Extreme Motherboard Review 41 | TweakTown.com

Next, we move to NVMe testing with our SN850. This drive offered 7032 MB/s reads and 4978 MB/s write.

ASUS ROG Crosshair VIII Extreme Motherboard Review 42 | TweakTown.com

The Thunderbolt ports were tested with the SN750 in an enclosure. This gave us a peak of 2785 MB/s read, and 1093 MB/s write.

ASUS ROG Crosshair VIII Extreme Motherboard Review 43 | TweakTown.com

Gen2x2 was tested with our WD P50, results coming in at 1594 MB/s read and 1581 MB/s write.

ASUS ROG Crosshair VIII Extreme Motherboard Review 44 | TweakTown.com

Last, we have USB 3.2 Gen 2. This reached 1030 MB/s read and 946 MB/ write.

Our last metric is how well the integrated heat sinks cool the SN850 during testing. In the middle of testing, we refreshed CDI to see a temp of 36c on our drive.

Final Thoughts

Having been in the market for over two years, AMD's X570 chipset is aging rapidly. However, ASUS is looking to breathe life into the platform by offering one of the most complete packages we have seen to date.

At the top, this board has nearly every connectivity option possible, including Thunderbolt 4 and USB 3.2 Gen2x2. Additionally, we have 10Gbe, Wi-Fi 6e, and 2.5Gbe for a complete network stack, and storage capability is out of this world with five m.2 slots and 6 SATA ports.

EFI and software are about as complete as they come; most of us know the ROG BIOS, and the Extreme doesn't disappoint with a full suite of tools for configuring your hardware and overclocking along with built-in secure erase for NVMe. Armoury Crate has grown and become a fantastic solution for monitoring and controlling RGB within Windows.

Pricing may sting for some; at $799 MSRP, this board certainly isn't cheap but does offer one of the most complete platforms for enthusiasts running AMD's Ryzen CPU.

What We Like

Design: Board design, layout and components all great.

Connectivity: Stacked connectivity.

Compatibility: Huge CPU support back to Ryzen 2000.

What Could Be Better

Price: $799 is about as high as it gets for X570.
