Tests de performance CPUs

Shared tests with results for both models: 2

Blender Cycles

Each row uses one Blender version, operating system and compute backend.

Test and settings	AMD Ryzen 9 8940HX	AMD Ryzen 9 7945HX	Result difference¹
Blender 5.2.0 / CPU / Windows	486.779796 samples/min Submissions: 14	473.887987 samples/min Submissions: 6	-2.6 %

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.

Individual model tests

These results have no shared test of both models with the same version and settings. They are shown separately without a percentage difference.
