It was solved with introduction of cache
NO, nothing is. Is not because causes a bottleneck in the RAM
The von Neumann bottleneck refers to the limitation in processing speed caused by the separation of memory and processing units in a computer system. This bottleneck can slow down the performance of modern computer systems by creating delays in data transfer between the memory and processing units, leading to decreased efficiency and overall speed of operations.
The limited throughput between the CPU and memory. The amount of work that a CPU can get done in the time that it takes to retrieve a piece of information from memory is increasing. As this increases, the amount of time a CPU spends waiting for data to be fetched from memory (i.e. "doing nothing") outpaces the amount of time the CPU spends doing actual work. Thus, a faster CPU no longer translates to a faster computer - the limiting part ("bottleneck") of the computer becomes the throughut (bandwidth and latency) between the CPU and memory. This is the "Von Neumann Bottleneck". It is called the "Von Neumann" bottleneck because it's a potential bottleneck on computers that use "von neumann architecture" (see: http://en.wikipedia.org/wiki/Von_neumann_architecture ), which is pretty much every general purpose computer in existence today. The concept of the "Von Nuemann Bottleneck" has been receiving increased attention lately, as many people feel that it is becoming a problem that will only be overcome with fundamental design changes in computer and/or CPU architecure.
