First up, 3DMark scores. In the Time Spy and Time Spy Extreme tests the card is about 19 percent faster than the RTX 3080.
A second leak suggests gaming performance may not be that impressive. A combination of synthetic and real-world gaming performance leaked by the Chinese TecLab team shows gains of around 10 percent or lower versus the 3080. If accurate, this would be quite disappointing.
Then there are also Blender benchmark leaks. These scores put the RTX 3090 about 20 percent above the RTX 3080.
