3DMark Benchmark (DirectX, Raytracing)
3DMark is a benchmark program that determines the performance of certain components of a computer and then reports the performance as a numerical value.

The AMD Radeon RX 6800 XT has 4608 shader units and these clock a maximum of 2.25 GHz which results in an FP32 computing power of 20.74 TFLOPS.

The MSI GeForce GTX 1080 Ti AERO 11G has 3584 shader units and these clock at a maximum of 1.58 GHz and achieve an FP32 computing power of 11.34 TFLOPS.
In FP32 performance, the AMD Radeon RX 6800 XT is 83 % faster than the MSI GeForce GTX 1080 Ti AERO 11G.

3DMark is a benchmark program that determines the performance of certain components of a computer and then reports the performance as a numerical value.
Cyberpunk 2077 was developed by CD Projekt Red and is based on the development studio's own REDengine 4. Ray tracing is switched off in our benchmarks.
The Last of Us Part One is a game released by Sony in June 2013 exclusively for the Playstation and released for the PC in early 2023. The benchmark values here were determined at high details.
Battlefield 5 is a visually stunning game that is ideal as a graphics card benchmark. We test the game with maximum details on Windows 10.
Geekbench 6 is a cross-platform benchmark for main processors, which also carries out 3 different graphics benchmarks and outputs them in the form of a numerical value.
The theoretical computing power of the graphics card with single precision (32 bit) in TFLOPS indicates how many trillion FP32 floating point operations the graphics card (GPU) can perform per second.
