When you see two FPS numbers, there are two common but different ways to show the difference:
This compares the slower card to the faster card.
Example: (200 ÷ 202) × 100 = 99%
This shows how much more the faster card performs compared to the slower one.
Example: ((202 - 200) ÷ 200) × 100 = 1%
You naturally think: "If Core i9-13900K is only 99% as fast, then Core i9-13900KS should be 1% faster" — but that's incorrect.
The "1% faster" is measured against the slower card, not against the faster one. So both numbers (99% of and 1% faster) are mathematically correct at the same time.
