I upgraded from 3900X RTX3070 to 5900X RTX4090
But I didn’t see any increase in speed
The only difference is that the card usage is lower
Is this normal?

In this case the CPU could be the bottleneck here. :person_shrugging:

You mean I need to upgrade my CPU?
5950x or 7950x?
Is there a difference that I can feel?

well, maybe. I am not too familar with the amd cpu series yet but the 4090 gpu is so strong that I would definitely fit the most powerful cpu to support it. :slight_smile:

This is not normal. Post your benchmarks and compare them to similar systems.

Got your before and after benchmarks ?

Getting faster RAM might get you some speed. I think 3600MHz is the sweet spot for the 5900X. You can look that up though to double check.
