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: (RTX 3080 Ti FPS ÷ RX 6900 XT FPS) × 100
Example: (96.4 ÷ 98.1) × 100 = 98%
"X% faster"

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

Formula: ((RX 6900 XT FPS - RTX 3080 Ti FPS) ÷ RTX 3080 Ti FPS) × 100
Example: ((98.1 - 96.4) ÷ 96.4) × 100 = 2%
Why Someone Might Get Confused:

You naturally think: "If RTX 3080 Ti is only 98% as fast, then RX 6900 XT should be 2% faster" — but that's incorrect.

The "2% faster" is measured against the slower card, not against the faster one. So both numbers (98% of and 2% faster) are mathematically correct at the same time.

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 3080 Ti FPS) × 100
Example: (42 ÷ 44.1) × 100 = 95%
"X% faster"

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

Formula: ((RTX 3080 Ti FPS - RX 6900 XT FPS) ÷ RX 6900 XT FPS) × 100
Example: ((44.1 - 42) ÷ 42) × 100 = 5%
Why Someone Might Get Confused:

You naturally think: "If RX 6900 XT is only 95% as fast, then RTX 3080 Ti should be 5% faster" — but that's incorrect.

The "5% faster" is measured against the slower card, not against the faster one. So both numbers (95% of and 5% faster) are mathematically correct at the same time.
