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...

If that is the case, then the comparison should be correct. As there are no better timing if those register that you have put inside the IO. Unless you use phylite or altdq_dqs2. Can you try to use AltDDIO to see if the result is different?
