Test Setup
Please read our GPU Test Bench and Benchmarking Refresher for an explanation on our test system, procedures and goals. Note that since the writing of that article, we have since further upgraded our CPU to a Ryzen 7 5800X. More information on our GPU testing can be found here. Check out our KIT page where you can see all the components in our test system configuration for reviewing video cards.
We will be using an AMD Radeon RX 6900 XT and a GIGABYTE GeForce RTX 3090 GAMING OC video card. The GIGABYTE GeForce RTX 3090 GAMING OC has a very small slight factory overclock on the boost clock at 1755MHz versus a Founders Edition which is set at 1695MHz boost, that is the only difference to the spec. It is a small factory overclock, as factory overclocks go for the RTX 3090. This review, therefore, is specific to this video card.
We are using the latest drivers at the time of testing, which were AMD Adrenalin 21.8.1 dated 8/10/2021 and NVIDIA GeForce 471.41 dated 7/19/2021. We have enabled PCI-Express Resizable BAR in the motherboard BIOS so that is enabled for NVIDIA GPUs and AMD Smart Access Memory is enabled for AMD GPUs.
