titanX vs titanV speed, performance

I’m using titanX and titanV to train Yolo.
I use the same Yolo.exe file, but only slightly different datasets.

From the taks manager>performance,
I see the Utilization of Titan X is around 40% but the Titan V is around 10%.
Both show 12GB occupation on thier RAMs.

I mounted titan X and installed titan X driver, CUDA10 and cudnn.
Later, I added titan V and intalled titan V driver.

Does it affects titan V’s performance?
Should I uninstall all the programs and install them agian?
Or Should I uninstall the CUDA10 and re-install them?
