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: (Core i3-13100 FPS ÷ Core i5-12400 FPS) × 100
Example: (127 ÷ 142) × 100 = 89%
"X% faster"

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

Formula: ((Core i5-12400 FPS - Core i3-13100 FPS) ÷ Core i3-13100 FPS) × 100
Example: ((142 - 127) ÷ 127) × 100 = 12%
Why Someone Might Get Confused:

You naturally think: "If Core i3-13100 is only 89% as fast, then Core i5-12400 should be 11% faster" — but that's incorrect.

The "12% faster" is measured against the slower card, not against the faster one. So both numbers (89% of and 12% faster) are mathematically correct at the same time.
