Entity Framework, Load multiple entities by primary key in a single query while still using caching

I have a list of primary key ids for a table whose entities I want to pull into EF memory, modify, and then save.

With a single id you would do something like

var entity = dbContext.Entity.Find(id);

entity.SomeColumn = "something";

dbContext.SaveChanges()

Currently I'm doing something like this to pull all the entities to be modified in one RTT.

int[] ids = new int[] { 1, 2, 3, 4 };

Entity[] entities = dbContext.Entity
  .Where(c => ids.Contains(c.PrimaryKey))
  .ToArray();

Question being, is EF smart enough to know to check caching before going against my db? For instance, if entities 1-4 had already been attached to the context, there should be no db query made.
