Aggregate effective memory bandwidth if you use the CPU cache well. Graph databases are not compute intensive, nor are they particularly large data models, but they are extremely memory I/O intensive. The classic model for graph-oriented HPC was vast numbers of weak cores and barrel processors for this reason, though the utility of specialized hardware architectures has been greatly reduced by better software architecture for this purpose over time.
