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.

What impact does the von Neumann bottleneck have on the performance of modern computer systems?
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.
What is the main difference between a von neumann and a Harvard machine?
difference between von neumann and harvard machine
What is the key advantage of the Von Neumann architecture?
The key advantage of the Von Neumann architecture is its ability to store both data and instructions in the same memory unit, allowing for faster and more efficient processing of information.
What distinguishes the EDSAC from the previous computer?
EDSAC(1947 - 1949) Von Neumann designed the electronic discrete variable automatic computer(EDSAC) with a memory to hold a stored pogram as well as datas to.
What is another advantage of using a computer-generater model of a car?
Analog computer Digital computer Hybrid computer Harvard architecture Von Neumann architecture Complex instruction set computer Reduced
