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: (Ryzen 9 9900X FPS ÷ Core i9-13900KS FPS) × 100
Example: (194.9 ÷ 202) × 100 = 96%
"X% faster"

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

Formula: ((Core i9-13900KS FPS - Ryzen 9 9900X FPS) ÷ Ryzen 9 9900X FPS) × 100
Example: ((202 - 194.9) ÷ 194.9) × 100 = 4%
Why Someone Might Get Confused:

You naturally think: "If Ryzen 9 9900X is only 96% as fast, then Core i9-13900KS should be 4% faster" — but that's incorrect.

The "4% faster" is measured against the slower card, not against the faster one. So both numbers (96% of and 4% faster) are mathematically correct at the same time.
