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: (Core i9-13900KS FPS ÷ Ryzen 9 7900X3D FPS) × 100
Example: (202 ÷ 212) × 100 = 95%
"X% faster"

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

Formula: ((Ryzen 9 7900X3D FPS - Core i9-13900KS FPS) ÷ Core i9-13900KS FPS) × 100
Example: ((212 - 202) ÷ 202) × 100 = 5%
Why Someone Might Get Confused:

You naturally think: "If Core i9-13900KS is only 95% as fast, then Ryzen 9 7900X3D 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.
