AMD IPU activation causes TDP increase?

[master255]

Today I updated the bios of my AyaNeo Kun computer with Ryzen 7 7840U and discovered a new AMD IPU device.
Since then, the minimum TDP of the console has increased significantly and even if the processor is doing nothing, it consumes 7-8 TDP, whereas before it was 1-3TDP.
Maybe the reason is that AMD IPU has been activated?

Comparison of processors with and without IPU.

Maybe these TDPs are used for a Trojan to spy on users?

Could it be this increase is due to BIOS issue, and not linked with the NPU per se. I believe AMD calls the AI circuit NPU.

@Dragomir-Ivanov you can find it. It says IPU and in device manager it's IPU too. And since its appearance, the minimum TDP has increased by 5-7 and the minimum temperature has increased by 2-5 degrees. The processor, even if it's not doing anything, is warming up around 50 degrees. It used to be 45.

Looks like I now have some backdoor in my CPU constantly running and consuming TDP.

@uday610 @gguasti What will AMD say?

Running extra hardware circuitry at CPU increases cpus power consumption. Even if you are not running a calculation on it, if you are feeding power to that circuitry, it consumes power... It's perfectly normal.
For my guess, the real problem is here that there are no power save code deployed yet to shut down integrated NPU when it not in use.

[master255]

@EUA If that "power save code" isn't deployed, I wouldn't want to have an IPU right now. And we need official comments

@uday610 @gguasti After playing a game, my CPU does nothing, but consumes at least 8TDP and warms up at least 50 degrees. At the same time, the CPU is running at less than 2GHz and only 6 cores of 16 are working. Obviously this is some kind of problem with AMD IPU. This started after activating the IPU.

[stisa]

have you tried going into device manager and disabling the IPU to see if it makes any difference? Device Manager -> System devices -> AMD IPU Device, then right click and "disable device".
Curious to see if that makes a difference for you, I haven't noticed any reduced battery life on my system (Flow X13).

[master255]

@stisa Tried it. It doesn't help. I think they made 5TDP the minimum instead of 0TDP. That's why it's more TDP now. But that still doesn't explain why no one from AMD is commenting on this popular topic.
