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 Sapphire Radeon RX 6900 XT has 5120 shader units and these clock a maximum of 2.25 GHz which results in an FP32 computing power of 23.04 TFLOPS.

The GIGABYTE GeForce RTX 3080 Vision OC 10G has 8704 shader units and these clock at a maximum of 1.80 GHz and achieve an FP32 computing power of 31.34 TFLOPS.
In FP32 performance, the GIGABYTE GeForce RTX 3080 Vision OC 10G is 36 % faster than the Sapphire Radeon RX 6900 XT.

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.
