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 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 typical of the AMD Ryzen 7 2700 CPU and fairly consistent across all motherboards, which is what we’d expect given the role AMD’s XFR2 and PB2 technologies play in ensuring CPU performance is always maximised within thermal and power constraints. There’s no performance deficit for B450 compared to X470 chipsets.
For a rough guide of how CPU performance compares to Intel’s Z370 platform, with an i7 8700K, please see KitGuru’s most recent Z370 motherboard review. Please note software and driver versions have changed hence why we caution that results are not directly comparable.
