General Explanation of Benchmark Percentages

When you see two FPS numbers, there are two common but different ways to show the difference:

"X% of the performance"

This compares the slower card to the faster card.

Formula: (RX 6900 XT FPS ÷ RTX 3090 Ti FPS) × 100
Example: (98.1 ÷ 100.7) × 100 = 97%
"X% faster"

This shows how much more the faster card performs compared to the slower one.

Formula: ((RTX 3090 Ti FPS - RX 6900 XT FPS) ÷ RX 6900 XT FPS) × 100
Example: ((100.7 - 98.1) ÷ 98.1) × 100 = 3%
Why Someone Might Get Confused:

You naturally think: "If RX 6900 XT is only 97% as fast, then RTX 3090 Ti should be 3% faster" — but that's incorrect.

The "3% faster" is measured against the slower card, not against the faster one. So both numbers (97% of and 3% faster) are mathematically correct at the same time.
