[GCN] Multicore doesn't mean equal core - Page 2

"A number of factors contribute to that variance, the researchers said. One factor is how the CPU hardware handles interrupts. In many cases, they could be directed to a single core, which could slow other applications on that core. However, if the interrupts are distributed across all the cores dynamically, there is no guarantee that the core handling the interrupt will be the same one that is running the program for which that interrupt was intended. Therefore, additional communication time is needed between the two cores."

Uh..isn't that what out of order executing cores/branch prediction is supposed to alleviate? I'm thinking yes.
