Test setup
By popular request, I again use a closed system, which is available in the form of a PC specially assembled for igor’sLAB by MIFCOM (exemplary product link, no affiliate) offers a really practical basis. The case used is really good, has enough internal volume and also an excellent airflow. The used AiO compact water cooling in the form of the Silen Loop II from Be Quiet fits visually to the overall concept and the RGB accents of RAM and motherboard can either be set to plain white or turned off completely in case of doubt. If it should get too colorful again.
I deliberately did without all the bling-bling in my configuration, but use a current AMD CPU in the form of the Ryzen 9 7950X and a solid motherboard from MSI (MEG X670E Ace) for the potent base. Here are a few pictures of my test system from the lab, including the RX 7900XT 20GB that was also tested today. And if you look closely: the RAM is just in the system for the power consumption measurement. Unfortunately I only have one that runs stable with DDR5 6000.
The PC was assembled nice and neat by MIFCOM (I always have it so with the cables) and can be purchased in this configuration (see below) exactly the same or modified at the dealer. It was simply important to me here to use a commercially available solution and not my extremely chilled out lab hardware in the climate oasis. There is enough space between the side panel (glass) and the graphics card and the storage space of the XL case was not even close to being used. Thus, even all other RTX 4080 (and RTX 4090) with the unspeakable adapter still have enough room to breathe. So that should fit, since the two Radeon cards have no problem with sprawling bending radii. I also only need two fans in the front.
However, the measurement of the detailed power consumption and other, deeper things is done in the lab on two tracks using high-resolution oscilloscope technology (there are also various follow-ups!) and the self-created, MCU-based measurement setup for motherboards and graphics cards (pictures below) or NVIDIA’s PCAT. Of course I use a redundant system for this, with the same components, because such measurements in the case are rather difficult.
The audio measurements are done outside in my chamber (room within a room).
I have also summarized the individual components of the test system in a table:
- 1 - Introduction, technical data and background
- 2 - Test system in the igor'sLAB MIFCOM-PC
- 3 - Gaming performance Full-HD (1920 x 1080)
- 4 - Gaming performance QHD (2560 x 1440)
- 5 - Gaming performance UHD (3840 x 2160)
- 6 - Power consumption and load balancing
- 7 - Transients and PSU recommendation
- 8 - Summary and conclusion
