Bottlenecking Theory - It does Exist in 2017 !
Here is my opening thoughts on Bottlenecking
This is a definition of a Bottleneck
Bottleneck is a kind of hardware limitation in your computer. A bottleneck occurs when the capacity of an application or a computer system is severely limited by a single component. Components that often bottleneck are graphic card, processor and HDD. Bottlenecks affect microprocessor performance by slowing down the flow of information back and forth from the CPU and the memory. If all of the components of a system are not able to feed the same amount of data at the same speed, a delay is created.
eg, a 2GB processor will be severely bottlenecked by an 800MB memory bandwidth.
Bottlenecking really affects Gaming rigs but applies to all rigs
The main culprits of jerky game play is mis-matched components like CPU to GPU & should be obsolete to use mechanical hard drives for os system.
I have experienced GPU bottle necking when I use an FX-6350 CPU with a GT 730 GPU, the CPU averaged at 50% the GPU wanted more than 100% causing too much stutter so had to change the CPU back to a FX-4170.
Amdahl's law
In computer architecture, Amdahl's law (or Amdahl's argument[1]) gives the theoretical speedup in latency of the execution of a task at fixed workload that can be expected of a system whose resources are improved. It is named after computer scientist Gene Amdahl, and was presented at the AFIPS Spring Joint Computer Conference in 1967.
? Does anyone understand this formula & know how to apply it to a PC config
So what I would like to discuss with any of you is how do we work a formula out to ensure all components talk to each other at the same speed so not to bottleneck our systems from the start, there is no point in buying a top end GPU if your CPU (mid range type) can not communicate with it fast enough which in reality means the GPU purchase is a waste of money for the processor you already have ???
You would definately get better drawing from a GPU to match the aforementioned CPU giving you a much better gameplay.
People take what is said as a bottleneck as an insult but I would just be quoting the theory on Bottlenecking.
If you have had a bad time with a graphics card find the bottleneck calculator & you may find your GPU or CPU was bottlenecking giving proof of theory...
Please feel free to think about this & reply with your thoughts on this matter :)
