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: (142 ÷ 147) × 100 = 97%
This shows how much more the faster card performs compared to the slower one.
Example: ((147 - 142) ÷ 142) × 100 = 4%
You naturally think: "If Core i5-12400 is only 97% as fast, then Ryzen 9 5900X should be 3% faster" — but that's incorrect.
The "4% faster" is measured against the slower card, not against the faster one. So both numbers (97% of and 4% faster) are mathematically correct at the same time.
