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: (53.5 ÷ 59) × 100 = 91%
This shows how much more the faster card performs compared to the slower one.
Example: ((59 - 53.5) ÷ 53.5) × 100 = 10%
You naturally think: "If RX 6650 XT is only 91% as fast, then B580 should be 9% faster" — but that's incorrect.
The "10% faster" is measured against the slower card, not against the faster one. So both numbers (91% of and 10% faster) are mathematically correct at the same time.

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: (39.8 ÷ 42.3) × 100 = 94%
This shows how much more the faster card performs compared to the slower one.
Example: ((42.3 - 39.8) ÷ 39.8) × 100 = 6%
You naturally think: "If RX 6650 XT is only 94% as fast, then B580 should be 6% faster" — but that's incorrect.
The "6% faster" is measured against the slower card, not against the faster one. So both numbers (94% of and 6% faster) are mathematically correct at the same time.

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: (20.9 ÷ 26.1) × 100 = 80%
This shows how much more the faster card performs compared to the slower one.
Example: ((26.1 - 20.9) ÷ 20.9) × 100 = 25%
You naturally think: "If RX 6650 XT is only 80% as fast, then B580 should be 20% faster" — but that's incorrect.
The "25% faster" is measured against the slower card, not against the faster one. So both numbers (80% of and 25% faster) are mathematically correct at the same time.
