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: (Ryzen 9 5900X FPS ÷ Core i5-12600K FPS) × 100
Example: (147 ÷ 157) × 100 = 94%
"X% faster"

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

Formula: ((Core i5-12600K FPS - Ryzen 9 5900X FPS) ÷ Ryzen 9 5900X FPS) × 100
Example: ((157 - 147) ÷ 147) × 100 = 7%
Why Someone Might Get Confused:

You naturally think: "If Ryzen 9 5900X is only 94% as fast, then Core i5-12600K should be 6% faster" — but that's incorrect.

The "7% faster" is measured against the slower card, not against the faster one. So both numbers (94% of and 7% faster) are mathematically correct at the same time.
