Parts:
Ryzen 1700
MSI Gaming Carbon Pro x370
16GB DDR4 (3000) T-force Delta II
EVGA 1060GTX (Old Card)
ZOTAC GAMING GeForce RTX 2080 Ti AMP Extreme Core
Corsair RM650 semi-modular power supply
Problem:
After getting the new card and installing it. It's benchmark performance and in-game performance is less than the 1060GTX. 3dMark, MSI Kombustor, CSGO and others all perform worse. Lower scores and lower frame rates.
Attempted Actions -Safe Mode DDU (driver uninstall) and reinstall multiple times -Tried alternative PCI-Ex16 slot -Replaced Modular PCI-E power cables
Additional Notes: I think I've narrowed it down to either the power supply or the card itself. After the testing I swapped back to the 1060GTX and it runs right around where a 1060 should.
Additionally during the testing the power consumption percentage for the Zotac stayed mostly in the 40% range occasionally spiking to 60% once. (The 1060 went to 100% for the benchmarks) The Core clock never really went above the base clock frequency.
This is a pretty expensive card that I just got so I want to try to eliminate all other problems. Other note is that even during benchmarks the Temp never really got above 50-52C.
The only thing I can think of beside the card at this point is the power supply. But if it couldn't provide the power I believe that it would cause other stability issues in the system instead of just not giving the performance. Meaning it would be crashing the computer because of drops in power on other parts (RAM,Mobo,Others)
