Amd driver bug: clearly no graphics card but eat a CPU core!

The editor of TPU recently found a strange phenomenon in the evaluation: on an older platform, a NVIDIA video card was replaced, but the system was extremely slow, and the startup, Internet access, testing and so on were all stuck to death.

Although the processor of this system is still the Pentium g3220t of the four generations of core family seven years ago, with dual core and dual thread, and 2.6GHz frequency, it has been running normally with an AMD video card before, but only a new one has been replaced. Is NVIDIA the cause of this problem?

As a result, open the task manager and find that one of the two CPU cores has always occupied 100%.


And switch to the process tab and finally find the culpritAmd graphics card driver setup program RadeonSettings.exe It has been occupying up to 50% CPU resources, which is one of the two cores.

After the completion of the city, the system finally recovered as before.


Obviously, this is a Bug that AMD drivesIf the driver is not unloaded in advance and the graphics card is replaced directly, the AMD driver process will still start automatically, but because the graphics card cannot be found, it will fall into some kind of infinite loop and consume a lot of CPU resources, especially in the low-end dual core configuration, the impact is very obvious.

As a matter of fact, this Bug is often encountered in our own reviews of fast technology, only because the processor configuration of the test platform is the top, generally non-aware, and is often remembered after finding an exception to the running score

After further research, TPU editors found that,The bug comes from a scheduled task set up after the AMD driver is installedEven if there is no video card, it will not terminate itself, but become a headless fly.



NVIDIA does not have such a problem, do not unload the driver and replace the graphics card, although various services are still available, but will not consume system resources.

We have reported this bug to AMD and look forward to fixing it as soon as possible.
