| + | # Power Modes & Performance |
| + | |
| + | :::warning |
| + | # Warning |
| + | This article is a work in progress! |
| + | ::: |
| + | |
| + | ### Intro |
| + | This guide is supposed to show how the performance of the APU changes on various power levels and to help you pick the optimal power mode for your Strix Halo system. |
| + | |
| + | All tests were run at fixed fans speed of 80% to make sure that cooling level is constant, CPU temp never exceeded 75 °C. For GPU becnhmarks please note that the GPU was in a passthrough mode to the Windows VM and only 12 CPU cores were passed as well, so there is at least 5% of a performance drop. In general, look at the percentage changes. |
| + | |
| + | **Everything single-threaded is omitted here, since a single core could never use the full power limit even if it's 55W.** |
| + | |
| + | ### CPU - PassMark |
| + | Details: |
| + | - [PassMark PerformanceTest for Linux](https://www.passmark.com/products/pt_linux/download.php), version 11.0.1002 |
| + | - Average of 5 medium tests for CPU, to lower the influence of the initial power boost (`./pt_linux_x64 -i 5 -d 2`) |

| + | :::info |
| + | # Notice |
| + | Geekbench does NOT test the system under full load, a lot of the tests don't even utilize all of the available cores, consider these results to be a reflection of an average daily lite usage with no extreme load |

| + | |
| + | Details: |
| + | - [Geekbench for Linux](https://www.geekbench.com/download/), version 6.4.0 |
| + | - 1 test on every power mode with a 3 minute delay |

| + | ### GPU - Gaming |
| + | `WIP` |
| + | |
| + | ### Conslusions |
| + | **For CPU** we have a classic situation of diminishing returns, where **85W mode seems to be the sweet spot**. Going higher doesn't make much sense unless you want to squeeze the absolute maximum out of your system, and going lower is only suitable if you don't use your system resources fully (especially when you don't utilize all of the cores) or don't care about performance loss. |
| + | |
| + | **For GPU** the situation is a bit different, seems that it can utilise power more effectively, but more testing is needed, I'm on it. |
