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 ÷ GTX 1660 Super FPS) × 100
Example: (21.7 ÷ 38.3) × 100 = 57%
"X% faster"

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

Formula: ((GTX 1660 Super FPS - RX 6400 FPS) ÷ RX 6400 FPS) × 100
Example: ((38.3 - 21.7) ÷ 21.7) × 100 = 76%
Why Someone Might Get Confused:

You naturally think: "If RX 6400 is only 57% as fast, then GTX 1660 Super should be 43% faster" — but that's incorrect.

The "76% faster" is measured against the slower card, not against the faster one. So both numbers (57% of and 76% faster) are mathematically correct at the same time.
