I wondered - why there is so many performance levels for GPU?

It should have just two

 - basic(power saving) at 300mhz - which should be unmodifiable and default when it boots and idle.
 - work(performance) - user defined settings, depending on application

Its obvious - for each given work task you normally choose 5 values
 - memory timings(strap, lets consider this as single parameter)
 - core amd memory voltages to limit power and fit some required consumption (or to fit ambient temps)
 - last one is their clocks at which gpu just go "cool, efficient and stable"

fan control is a different story, normally i just run it at stable fixed 100% or 80% if fan is cheap bad bearing.

So a "performant level" is a combo of those 5 params, which should be carefully chosen for every different workload.

So my questions are:

- What are "factory defaults" for a gpu?
- For what task were they tweaked? (Obviously not for mining, neither to say each game rendering program will require its own "level")
- Why there are 7! levels for core and 3!!! levels for memory (on my RX 580)? Isn't a complex system more prone to faults and errors?

Yeah that makes total sense to only have two levels for a GPU.

I suppose you drive your car that way too? Either idle or pedal floored as obviously there is no need for anything in between!

Best answer for the op question ever , sometimes i wish we have a like button on this forum ;)

You always have the merit button which kinda acts like the kike button only is a bit more privileged as it boosts the other person rank. I think keeping the miners in medium performance just like constantly pressing that pedal of gas in your car is the best to do.

Everyone not only in mining but in every other category is trying to find the perfect spot between power and balance.

It is made to economize the consumption and performance of GPU in different conditions. You have a different load of GPUs when PC is sleeping, when you work in MS Office, when you are watching video content, when you render graphics or play in a modern 3D game.
