"Prefetching on a coprocessor such as the Intel Xeon Phi coprocessor can be more important than on a main CPU such as the Intel Xeon CPUs. Since the cores on the Intel Xeon Phi coprocessor are in-order, they cannot hide memory latency as compared to an out-of-order CPU. In addition, since a coprocessor does not have an L3 cache, L2 misses must then access the slower memory subsystem."
