If it has a pittance of cache, then mechanical sympathy might not mean cache-friendliness. Linked lists were mechanically sympathetic on uncached systems - it cost the same to access any byte of memory, so you might as well go directly to the one you wanted.
Looking at the specs: 32 KiB of L1, 256 KiB of L2, in-order and partial dual-issue.
That's the least forgiving kind of chip when it comes to performance: fast enough to outpace main memory by two orders of magnitude, yet the slightest speed bump (branch misprediction, cache miss) stalls it without any ability to reorder around it.
What is a cache friendly version of linked lists?
