In our custom build, the links were reordered in the data structure to minimize the cases where adjacent links shared a common node. This creates a gap between the time when a node position is updated and when it is next read, which in turn allows the CPU to continue execution without risking a dependency violation.
Reordering the links, together with arranging them sequentially in memory, results in speed increases for the A7 in our 3DMark custom build. However, the iPhone 5s would only gain a couple of places in our Best Mobile Devices list with this build and would still trail behind the latest Snapdragon 800 devices.
There was no performance benefit when we tested the iPhone 5 with our custom build. What's more, we found that performance decreased slightly on some Android devices due to the extra processing steps required to reorder the links.
