Performance Test
Due to time constraints, the tests were conducted in the default Balanced mode.
Performance benchmarks power consumption summary table (against RTX 3080/3090 results):
amd radeon rx 6900xt review 14
The difference between the RX 6900 XT and the RX 6800 XT lies only in the last 10% of the units completed, compared to the RX 6800 XT only 5% improvement, if the game optimization is done well, the RX 6900 XT can challenge the RTX 3090 capital.
amd radeon rx 6900xt review 15
The RX 6900 XT and the GeForce RTX 3090 also rely on the compatibility and optimization of gaming features. However, the 7nm process and the 300W power consumption setting make the RX 6900 XT an even better power consumption performer among high-end cards.
