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 6400 FPS ÷ RX 5500 XT 4GB FPS) × 100
Example: (21.7 ÷ 29.6) × 100 = 73%
"X% faster"

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

Formula: ((RX 5500 XT 4GB FPS - RX 6400 FPS) ÷ RX 6400 FPS) × 100
Example: ((29.6 - 21.7) ÷ 21.7) × 100 = 36%
Why Someone Might Get Confused:

You naturally think: "If RX 6400 is only 73% as fast, then RX 5500 XT 4GB should be 27% faster" — but that's incorrect.

The "36% faster" is measured against the slower card, not against the faster one. So both numbers (73% of and 36% faster) are mathematically correct at the same time.
