Reasons for no cache in K64

Hi, we are thinking about switching CPU from a Kinetis K60 to a K64, mainly for the increased RAM memory as well as the lower cost. When we compare the two cpu:s they are quite similar in most areas (except for the memories), but we see that the K60 has a cache with the size of 16.384kb and we can't find similar information about the K64 so we assume it has no such cache? What is the reason for this? Also, how would it affect the performance of our applications if we were to make the switch from K60 to K64?
