Ehh, as Ive and many told always, you cannnot compare ps in general vs pc, unless its per game , like BF1,Fifa and etc which are on both platfroms.
1050ti will struggle as i5-4440 in some titles against ps4, like shadow of mordor.
Just an short answer why, because ps is optimized per game, runs 30fps always or 60*, in general ps is more cinematic but more fluid than pc at 30.
