In the world of computer hardware, when we talk about a ‘bottleneck’, we mean a part that holds back how well the whole system works. People usually focus on CPUs and GPUs as possible bottlenecks, but they don’t always think about how important motherboards are in this too.

Motherboards can bottleneck performance if they limit the speed or compatibility of components like CPUs, GPUs, and RAM. Choosing a suitable motherboard prevents bottlenecks and ensures optimal system performance.

In this article, we’ll explore the concept of motherboard bottlenecking, its causes, and how to address it effectively.
