7-Zip

7-Zip is an open source Windows utility for manipulating archives. We measure the Total Rating performance using the built-in benchmark tool. The test stresses all CPU cores to 100% and shows an affinity for memory bandwidth.

Cinebench R15 and R20

Cinebench is an application which renders a photorealistic 3D scene to benchmark a computer’s rendering performance, on one CPU core, all CPU cores or using the GPU. We run the test using the all core CPU mode.

Sandra Processor Arithmetic

SiSoft Sandra 2018 is a multi-function utility program that supports remote analysis, benchmarking and diagnostic features for PCs, servers, mobile devices and networks. We run the application’s processor arithmetic test to gauge the CPU performance on each tested motherboard.

CPU performance is in line with expectations for a high-end Z390 motherboard. ASRock, like MSI, fully exploits all the performance available in the Core i9 9900K by making the maximum all-core Turbo speed (4.7GHz) persist indefinitely beyond Intel's normal turbo durations.

For a rough guide of how CPU performance compares to other platforms please see our most recent reviews for the following platforms:

B450/X470 (Ryzen 7 2700)
Z370 (Intel Core i7 8700K)
X299 (Intel Core i9 7900X)

To see comparisons of CPU performance with other Z390 motherboards that were tested using different drivers, a different version of Windows 10 and different application versions, see here.

Please note due to software, OS and driver versions changes we caution that results are not directly comparable but may still give indicative performance comparisons.
