General Explanation of Benchmark Percentages

When you see two FPS numbers, there are two common but different ways to show the difference:

"X% of the performance"

This compares the slower card to the faster card.

Formula: (A580 FPS ÷ RX 6600 FPS) × 100
Example: (54.7 ÷ 64.1) × 100 = 85%
"X% faster"

This shows how much more the faster card performs compared to the slower one.

Formula: ((RX 6600 FPS - A580 FPS) ÷ A580 FPS) × 100
Example: ((64.1 - 54.7) ÷ 54.7) × 100 = 17%
Why Someone Might Get Confused:

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.

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.
