| Performance* | ++++ Benchmark Results
Benchmark results with AMD Ryzen 7 9800X3D processor. Integrated AMD Radeon and PCIe 4.0 SSD. The benchmark integrated in CPU-Z results in 827 points in the single-core test and 8982 points in the multi-core test with a good multi-thread ratio of 10.86. SMT therefore also works with the new Ryzen 9000 series without any problems. Since CPU-Z is not exactly one of the most demanding CPU tests, we also run Cinebench R23 and achieve 2177 points in the single core test and 23454 points in the multi-core test. Due to the significantly higher load compared to CPU-Z, we are positively surprised to still achieve a multi-thread ratio of 10.77, especially since an Arctic Freezer 34 had to take over the cooling of the CPU. |
| Manual and Labeling | ++++ Well-placed, complete mainboard labeling. A quick guide with instructions for correct CPU installation, memory installation, M.2 installation, etc. is included. In addition, a complete user manual and instructions for installing a RAID array, overclocking and BIOS terminology are available to download online. |
