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.
These results have no shared test of both models with the same version and settings. They are shown separately without a percentage difference.
Results were obtained on the reported systems. Test versions and settings remain separate; incomplete conditions do not support calculated model performance differences.
