BIOS Walkthrough

Test Setup & Methodology

Processor: AMD Ryzen 9 3900X
Memory: G.Skill TridentZ RGB DDR4-3600 16GB
Storage: WD Blue SSD 1TB SATA
PSU: Seasonic Platinum 1050w
Cooling: AMD Wraith Prism
Monitor: Viewsonic VX2475smhl-4K

Note: Mid-way during this review AMD has released their AGESA update to fix boost clocks for their 3rd-gen Ryzen CPUs. We’ve included results for this motherboard specifically for comparison.

All tests are performed in an open bench with ambient room temperature kept at 30*C (welcome to the Philippines.)

Motherboards are updated to the latest BIOS during time of testing kept at their out-of-box settings aside from XMP frequencies when running stock benchmarks.

As many already know, most motherboards will have varying frequency multipliers and this may affect performance overall. As this is part of their out of the box configuration we see it fit to use them as is. All data presented here in are with the default motherboard settings for stock performance. Overclocked performance will be indicated where needed. For non-Z series motherboards, all benchmarks are performed on DDR4-2133 default settings.

As always, we’ll let the numbers do the talking.

Best Practices

  • Same thermal paste and same application method used on all cooler mounting. A pre-benchmark stress test is performed to let the TIM settle. We use Noctua NT-H1 for all our testing.
  • A fresh install of Windows 10 Pro is used for every sample testing. The OS image contains all benchmarks and games. Drivers are installed after image is installed.
  • An average of 3 benchmark runs is used for test sampling.

Performance Test – Rendering/Encoding

Rendering tests are benchmarks designed to gauge performance during multimedia and professional workloads like 3D rendering or video encoding. This gives us a good idea on how a certain system will perform during a certain predefined workload.

MAXON Cinebench CPU Benchmark R15

Blender BMW Render Benchmark 2.7

POV Ray 3.7

Cinegy Cinescore 10 – Ultra HD

HWBot x265

Performance Test – Arithmetic

Arithmetic benchmarks measure the performance of systems with regards to mathematical computations which some programs require. These benchmarks paint a good picture of how raw CPU performance is like.

wPrime 1024M

SuperPI 32M

Performance Test – System Benchmark

System benchmarks measure the performance of a system based on numerous tasks including a mix of rendering, arithmetic and other things. These benchmarks require the entire system to work together and components should compliment each other to achieve maximum performance.

GeekBench Pro 4.2 Multi-Core Benchmark

ASUS RealBench 2.56

Performance Test – Memory Benchmark

AIDA64 Memory Benchmark – Read/Write

AIDA64 Memory Benchmark -Latency

Temperature & Power Draw

In this test we’ll measure how much manufacturer-set BIOS settings affect temperature and power draw. As we’re dealing with pre-launch samples, more mature BIOS may change these over time.


Power Draw

We really don’t put too much stock on individual component temperatures as they will vary depending on usage and we do not benchmark using extreme loads anymore as they’re not reflective of real world applications. To stress the CPU, we use a 20-minute run of AIDA64 stress test. We recorded the peak CPU temps and cross-match HWINFO and AIDA64 readings. For power readings, we measure the peak system draw.

Value & Conclusion – ROG Crosshair VIII Formula

ASUS ROG Crosshair VIII Formula AM4 Motherboard Review

As mentioned, the AMD has not really implemented any new features for the X570 chipset aside from PCIe Gen4 and a new set of power standards for their new chips, perhaps to make room for the upcoming 16-core Ryzen 9 3950X. As it is though, X570 motherboards like the Crosshair VIII Formula will prove to be an excellent foundation should AMD support AM4 for at least 2 more generations. With the new parallel or teaming VRMs working efficiently to handle the higher power demands of the 12-core or more AMD processors, this board can be reliably used should AMD not change anything further for their socket or power requirements.

That said, benchmarks for the entire X570 lineup is more of a test of what could be wrong rather than whats right about a motherboard and as we can see, the ASUS ROG Crosshair VIII Formula easily maintains its position as a flagship. The AGESA update only improved single-core performance by a bit so out of the box this motherboard should be able to deliver the best performance from your Ryzen CPUs.

With no Extreme-class motherboard in sight, the ASUS ROG Crosshair VIII Formula serves as the big dog for the ROG X570 board brand, still it skips out on some of niceties that we see from other brands. Still, this is offset by an incredibly robust VRM and excellent board features to support many high-end build configurations.

ASUS ROG Crosshair VIII Formula AM4 Motherboard Review

ASUS has not had much chances to play around with the Crosshair series but the last 3 years have proven a haven in furthering the godfather of the ROG class motherboard. While the X570 by itself is, from a tech improvement perspective a totally weak release, motherboard makers have poured a lot into their new boards and the current flagships are a signs that we’ll get to see some of these tech eventually trickle down to the mainstream.

Still, at $650 the ASUS ROG Crosshair VIII Formula is a premium offer but the same goes for much of the X570 flagships as of this moment. From a value proposition, the motherboard offers a lot to consider from aesthetics to features and connectivity is looking ready to handle a lot of future tech coming in the next years. 

If you want the top end ROG board for your 3rd-gen Ryzen 9 build, the ASUS ROG Crosshair VIII Formula is your boy and it offers a great foundation for a top end AMD build.

ASUS backs the ROG Crosshair VIII Formula with a 3-year warranty. We give it our B2G Gold Award!
