Maximizing The Performance & Power Efficiency Of AMD Ryzen AI Max+ 395 With Platform Profiles
With the Speedometer 3.0 browser benchmark running in Mozilla Firefox, switching to the performance mode boosted the performance by 6% while the SoC power consumption went up by just 3%. The low-power / power-saver mode led to a big performance drop while the SoC power consumption was more than halved -- consuming even less power than the Intel Core Ultra 7 258V Lunar Lake.
Google Chrome performance also benefited from the performance platform profile with the Jetstream 2 benchmark improving by just over 1% and lower power consumption on average than the default but with a higher peak.
Switching to the performance profile helped squeeze out slightly more performance out of the AMD Ryzen AI Max+ 395 for not much of an impact on the power use.
For more demanding creator-type workloads like Blender 3D modeling, the performance profile can shave off several seconds of render times albeit the Ryzen AI Max+ PRO 395 power consumption went up by several Watts. The low-power mode meanwhile delivered slightly better power efficiency to this HP ZBook Ultra G1a laptop.
