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: (54.7 ÷ 64.1) × 100 = 85%
This shows how much more the faster card performs compared to the slower one.
Example: ((64.1 - 54.7) ÷ 54.7) × 100 = 17%
You naturally think: "If A580 is only 85% as fast, then RX 6600 should be 15% faster" — but that's incorrect.
The "17% faster" is measured against the slower card, not against the faster one. So both numbers (85% of and 17% 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: (43 ÷ 43.7) × 100 = 98%
This shows how much more the faster card performs compared to the slower one.
Example: ((43.7 - 43) ÷ 43) × 100 = 2%
You naturally think: "If A580 is only 98% as fast, then RX 6600 should be 2% faster" — but that's incorrect.
The "2% faster" is measured against the slower card, not against the faster one. So both numbers (98% of and 2% 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: (27.6 ÷ 27.9) × 100 = 99%
This shows how much more the faster card performs compared to the slower one.
Example: ((27.9 - 27.6) ÷ 27.6) × 100 = 1%
You naturally think: "If A580 is only 99% as fast, then RX 6600 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: (14.4 ÷ 16.4) × 100 = 88%
This shows how much more the faster card performs compared to the slower one.
Example: ((16.4 - 14.4) ÷ 14.4) × 100 = 14%
You naturally think: "If RX 6600 is only 88% as fast, then A580 should be 12% faster" — but that's incorrect.
The "14% faster" is measured against the slower card, not against the faster one. So both numbers (88% of and 14% faster) are mathematically correct at the same time.
