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: (GTX 1660 Super FPS ÷ RX 6600 FPS) × 100
Example: (38.3 ÷ 43.7) × 100 = 88%
"X% faster"

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

Formula: ((RX 6600 FPS - GTX 1660 Super FPS) ÷ GTX 1660 Super FPS) × 100
Example: ((43.7 - 38.3) ÷ 38.3) × 100 = 14%
Why Someone Might Get Confused:

You naturally think: "If GTX 1660 Super is only 88% as fast, then RX 6600 should be 12% faster" — but that's incorrect.

The "14% faster" is measured against the slower card, not against the faster one. So both numbers (88% of and 14% faster) are mathematically correct at the same time.
