Test system and evaluation software
The benchmark system is new and is now not only in the lab, but also again as a double in the editorial office. I’m also going for PCIe 4.0, the right X570 motherboard in the form of an MSI MEG X570 Godlike (gaming benchmarks) and an MSI MEG X570 Ace (measurement lab) respectively, and a select Ryzen 9 5900X in each case, both water-cooled and overclocked to 4.7GHz. In addition, the matching DDR4 3800 RAM (Corsair, G.Skill) and several fast NVMe SSDs. For direct logging during all games and applications, I use NVIDIA’s PCAD, which adds to the convenience immensely.
The measurement of the power consumption and other things takes place here in the special laboratory on a redundant and almost identical test system then double-tracked by means of high-resolution oscillograph technology…
…and the self-created MCU-based measurement setup for motherboards graphics cards (pictures below), where at the end in the air-conditioned room also the thermographic infrared images are created with a high-resolution industrial camera. The audio measurements are done outside in my chamber.
I have also summarized the individual components of the test system in a table:
