There is plenty of algorithms in which CPU produces continuous blocks of new data (specifically when using Data Oriented Design). In such case we want to be sure that produced data will be transferred to RAM without disturbing CPU computation. Unfortunately this is not always the case in modern CPU architectures. First write to the given memory adress will cause so called write-miss. Write misses have no impact on CPU if given memory location is treated by caching mechanism as write-through.. Read More
