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 4080 FPS ÷ RTX 5090 FPS) × 100
Example: (175 ÷ 197.5) × 100 = 89%
"X% faster"

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

Formula: ((RTX 5090 FPS - RTX 4080 FPS) ÷ RTX 4080 FPS) × 100
Example: ((197.5 - 175) ÷ 175) × 100 = 13%
Why Someone Might Get Confused:

You naturally think: "If RTX 4080 is only 89% as fast, then RTX 5090 should be 11% faster" — but that's incorrect.

The "13% faster" is measured against the slower card, not against the faster one. So both numbers (89% of and 13% faster) are mathematically correct at the same time.
