KFA2 GeForce RTX 3080 Ti SG (One Click OC) 12GB in review – Solid performance and even a bit cheaper in comparison with others
Benchmarks, Test system and evaluation software
For the benchmarks, I chose the same 10 games again, analogous to the launch article, and weighted between old and new, as well as AMD- or NVIDIA-specific. Since everything is very similar to the launch article of the Radeon cards, this time there is only a cumulative summary of all games with a detailed explanation for each resolution. The power consumption is also very detailed, as you are used to.
The benchmark system is known and I use PCIe 4.0 and suitable X570 motherboards in the form of the MSI MEG X570 Godlike as well as a selected Ryzen 9 5900X that was overclocked water-cooled (PBO + 500 MHz) for better comparability to then. This is complemented by the matching DDR4 4000 RAM from Corsair, as well as several fast NVMe SSDs. For direct logging during all games and applications, I use my own measurement station with shunts and riser card, as well as NVIDIA’s PCAT in games, which increases the comfort immensely.
The measurement of the detailed power consumption and other, more in-depth things is then carried out here in the special laboratory on a redundant test system that is identical down to the last detail, on two tracks using high-resolution oscillograph technology…
…and the self-created MCU-based measurement setup for motherboards and 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 (room within a room).
I have also summarized the individual components of the test system in a table:
