In the conventional von Neumann model, where computing systems are physically and logically split between memory and CPUs, the “memory wall” and “power wall” are well known bottlenecks that have severely limited the energy efficiency of many applications. Running today’s memory intensive applications, modern computers spend most of their time and energy moving data rather than on computation.
