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 now. 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.
System Setup
We are using the motherboard’s current default BIOS settings except that we have ENABLED PCI-Express Resizable BAR (AMD Smart Access Memory) and DOCP. Yes, we are using Resizable BAR for the best performance on all video cards, and the video cards have their BIOS updated to support it.
For our comparison today we are going to use the GeForce RTX 3080 Founders Edition so that we can see how much faster the GeForce RTX 3090 is. We can see how much more game performance it adds. We are also including the Radeon RX 6800 XT for another data comparison point. The GeForce RTX 3080 and Radeon RX 6800 XT have similar MSRPs.
