AMD Radeon RX 6800 XT & Radeon RX 6800 16 GB Graphics Cards Review – Here’s Big Navi!

AMD Radeon RX 6800 XT / RX 6800 Syntethic Benchmarks And Thermal Performance

Firestrike

Firestrike is running the DX11 API and is still a good measure of GPU scaling performance, in this test we ran the Extreme and Ultra versions of Firestrike which runs at 1440p and 4K and we recorded the Graphics Score only since the Physics and combined are not pertinent to this review.

Time Spy

Time Spy is running the DX12 API and we used it in the same manner as Firestrike Extreme where we only recorded the Graphics Score as the Physics score is recording the CPU performance and isn't important to the testing we are doing here.

Port Royal

Port Royal is another great tool in the 3DMark suite, but this one is 100% targeting Ray Tracing performance. It loads up ray traced shadows, reflections, and global illumination to really tax the performance of the graphics cards that either have hardware-based or software-based ray tracing support.

Thermals

Thermals were measured from our open test bench after running the Time Spy graphics test 2 on loop for 30 minutes recording the highest temperatures reported. The room was climate controlled and kept at a constant 22c throughout the testing.

*Hot Spot only reported on cards that feature that monitoring point.
