TDP

[johnny-nc]

Let’s say you observe that a game never goes above 11 W during gameplay. Is there any benefit to setting a TDP limit of 11 W for that particular game if it never uses more than 11 Watts anyway?

The reason I ask is I have seen YouTubers talking about setting a TDP limit of 3 for very basic games and I wonder what the benefit is of doing this if the game isn’t using very many watts already?

I may have some fundamental misunderstanding of the whole situation and that’s why I am asking to get some clarity about how all this works.

The benefits of setting the TDP are to lower APU temps & extend battery life. If you set it at the max the game uses instead of the max as the APU comes set at, it will also help lengthen life of the device as higher temps shorten lifespan of the battery & chip. You can also lower the frequency of the GPU at the same time & also get the above benfits.

The biggest benefit is for old games rather than "basic" games, because they weren't made with modern multicore dynamically-clocked processors in mind. For example, the other day I was playing a 20-year-old game that decided to pull 17 W on the Deck. So I dropped the GPU to 3 W and the GPU to 200 MHz and it was much happier.

is there an echo in here?

I’ve been playing Arkham Origins and based on the replies in this thread I decided to tinker with the TPU limit and GPU frequency. I set both almost as low as they can go but the temps are staying the same 🤔
