Full HD — max settings
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: (59 ÷ 64.3) × 100 = 92%
This shows how much more the faster card performs compared to the slower one.
Example: ((64.3 - 59) ÷ 59) × 100 = 9%
You naturally think: "If B580 is only 92% as fast, then RX 6700 XT should be 8% faster" — but that's incorrect.
The "9% faster" is measured against the slower card, not against the faster one. So both numbers (92% of and 9% faster) are mathematically correct at the same time.

1440p QHD — max settings
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: (42.3 ÷ 47.9) × 100 = 88%
This shows how much more the faster card performs compared to the slower one.
Example: ((47.9 - 42.3) ÷ 42.3) × 100 = 13%
You naturally think: "If B580 is only 88% as fast, then RX 6700 XT should be 12% faster" — but that's incorrect.
The "13% faster" is measured against the slower card, not against the faster one. So both numbers (88% of and 13% faster) are mathematically correct at the same time.
4K Ultra
3840×2160 — max settings
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: (26.1 ÷ 26.9) × 100 = 97%
This shows how much more the faster card performs compared to the slower one.
Example: ((26.9 - 26.1) ÷ 26.1) × 100 = 3%
You naturally think: "If B580 is only 97% as fast, then RX 6700 XT should be 3% faster" — but that's incorrect.
The "3% faster" is measured against the slower card, not against the faster one. So both numbers (97% of and 3% faster) are mathematically correct at the same time.
