Back in April I published Linux benchmarks of the Lenovo ThinkPad T14s Gen 6 with the AMD Ryzen AI 7 PRO 360 SoC. Some follow-up benchmarks I did back then that I have been meaning to publish is looking at the ACPI Platform Profile impact on performance and power for this ThinkPad laptop under Linux. Here are those numbers.
With a busy past number of weeks with all of the AMD Strix Halo testing and the like, these platform profile numbers had fallen through the cracks for publishing. As shown in the numerous Platform Profile article benchmarks, adjusting the ACPI platform profile from the default to either a performance-optimized or battery-optimized state can make a big difference to performance and power efficiency. But these platform profiles are set by the vendor and ultimately also a factor of the cooling capabilities and overall design of the particular laptop in question. So for those with a Lenovo ThinkPad T14s Gen 6 or thinking about getting one and wondering the impact there, these benchmark results are for you.
Using the Lenovo ThinkPad T14s Gen 6 with AMD Ryzen AI 7 PRO 360, I ran tests at the default balanced state and then switching the Platform Profile over to the “performance” profile and lastly to the low-power profile for seeing the efficiency gains.
All these tests were done on Ubuntu 25.04 back in April with the Linux 6.14 kernel.
As shown in numerous past articles, changing the ACPI Platform Profile can make a significant difference to the performance and power use. In total around 200 benchmarks were run at each platform profile and all the individual results in full can be found via this result page. In cutting to the chase:
With the geo mean of all the raw performance benchmarks ran in full, switching from the default balanced profile to the performance profile boosted the performance overall by 19%. Switching to the low-power profile led to just 64% of the original out-of-the-box performance.
When factoring in the CPU power use, switching to the performance profile squeezing that 19% extra performance out of the Ryzen AI 7 PRO 360 led to the CPU power use on average going up by 61%. But for those wanting to extend battery life, switching to the low-power profile led to the CPU power use dropping from 13.97 Watts to 9.26 Watts. Or around 66% the default CPU power use and roughly inline with the performance hit observed overall.
This also correlates to a significant difference in CPU thermals too.
See this result page for all the individual performance benchmarks as well as CPU power and thermal data in full for those interested in the AMD Ryzen AI powered Lenovo ThinkPad T14s Gen 6 with Linux.
