AOM AV1 video encoding also performed faster with the cache bias set in the amd_x3d_mode sysfs interface.
Of course, some workloads do perform better on the frequency CCD default preference.
Some LiteRT (TensorFlow Lite) tests were helped with the 3D V-Cache Optimizer driver change.
It was interesting to measure the impact of making use of the new AMD 3D V-Cache Optimizer driver on Linux 6.13 for influencing the cache vs. frequency CCD selection with the Ryzen 9 9950X3D.
The Speedometer 3.0 web browser benchmark within Firefox on Linux was performing better with the amd_x3d_mode change.
