We’ll talk more about the details of the processes later. If they have huge differences in processing speed, bottleneck will happen. The components that are involved in the process of bottlenecking are the CPU (processor) and the GPU (graphics card). In other words, this means that the capacity to return a processed data is not enough compared to how much data is being sent for processing. Defining Bottleneck, CPU Bottleneck and GPU Bottleneckīottleneck, as for how it is named, occurs when there is a limit on how much data is being sent for processing or how much data can be processed at the same time.
