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: (B580 FPS ÷ RTX 2080 FPS) × 100
Example: (59 ÷ 64.9) × 100 = 91%
"X% faster"

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

Formula: ((RTX 2080 FPS - B580 FPS) ÷ B580 FPS) × 100
Example: ((64.9 - 59) ÷ 59) × 100 = 10%
Why Someone Might Get Confused:

You naturally think: "If B580 is only 91% as fast, then RTX 2080 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.
