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: (RTX 5080 FPS ÷ RTX 4090 FPS) × 100
Example: (178.5 ÷ 195.6) × 100 = 91%
"X% faster"

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

Formula: ((RTX 4090 FPS - RTX 5080 FPS) ÷ RTX 5080 FPS) × 100
Example: ((195.6 - 178.5) ÷ 178.5) × 100 = 10%
Why Someone Might Get Confused:

You naturally think: "If RTX 5080 is only 91% as fast, then RTX 4090 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.
