Much of the design is inherited from previous architectures such as {{\\|Haswell}} but has been widened to explorer more [[instruction-level parallelism]] opportunities. From the allocation queue instructions are sent to the [[Reorder Buffer]] (ROB) at the rate of 6 µOPs each cycle. Skylake's throughput is up by 2 µOPs per cycle from {{\\|Broadwell}} in order to accommodate the wider front-end. |
