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: (RX 7800 XT FPS ÷ RTX 3090 FPS) × 100
Example: (94.8 ÷ 97.2) × 100 = 98%
"X% faster"

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

Formula: ((RTX 3090 FPS - RX 7800 XT FPS) ÷ RX 7800 XT FPS) × 100
Example: ((97.2 - 94.8) ÷ 94.8) × 100 = 3%
Why Someone Might Get Confused:

You naturally think: "If RX 7800 XT is only 98% as fast, then RTX 3090 should be 2% faster" — but that's incorrect.

The "3% faster" is measured against the slower card, not against the faster one. So both numbers (98% of and 3% faster) are mathematically correct at the same time.
