Is "Cyclone 10 LP" slower than "Cyclone IV E" ?

I tested according to the same source code (VHDL) shown below. The reported delay was almost the same... but "Cyclone 10 LP" gave the following timing error @300MHz clock. Is my setting incomplete...

>Can you check does your ddio and non ddio register is inside the IO?

I checked using the resource property editor on both devices.

This time it was necessary to specify "Fast output Register" explicitly on both devices
