¹ Difference of the second result relative to the first in that row. No percentage is calculated for different upscaling algorithms. This compares published results, not a universal performance index.
A base GPU test is a reference for cards using that GPU and the same memory capacity. Board overclocking, cooling and power limits can change the result.
These results have no shared test of both models with the same version and settings. They are shown separately without a percentage difference.
Published measurements are separate from the archived index. Incomplete conditions and unknown run counts do not support ranking positions or calculated performance differences.
