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: (97.2 ÷ 98.1) × 100 = 99%
This shows how much more the faster card performs compared to the slower one.
Example: ((98.1 - 97.2) ÷ 97.2) × 100 = 1%
You naturally think: "If RTX 3090 is only 99% as fast, then RX 6900 XT 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.

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: (68.4 ÷ 69.3) × 100 = 99%
This shows how much more the faster card performs compared to the slower one.
Example: ((69.3 - 68.4) ÷ 68.4) × 100 = 1%
You naturally think: "If RX 6900 XT is only 99% as fast, then RTX 3090 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.

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: (42 ÷ 44.8) × 100 = 94%
This shows how much more the faster card performs compared to the slower one.
Example: ((44.8 - 42) ÷ 42) × 100 = 7%
You naturally think: "If RX 6900 XT is only 94% as fast, then RTX 3090 should be 6% faster" — but that's incorrect.
The "7% faster" is measured against the slower card, not against the faster one. So both numbers (94% of and 7% faster) are mathematically correct at the same time.
