🔍 Introduction If you've ever used a bottleneck calculator, you've probably seen a simple percentage telling you whether your CPU or GPU is holding your system back. But here’s the truth most people don’t realize: Bottlenecks are not fixed numbers — they are dynamic, workload-dependent behaviors. In this post, we’ll go beyond basic tools and break down how CPU and GPU bottlenecks actually work in real-world scenarios. ⚙️ What Is a Bottleneck (Technically)? A bottleneck occurs when one component limits the performance of another. CPU Bottleneck → Processor can’t keep up with GPU GPU Bottleneck → Graphics card limits overall performance However, this is context-dependent: Resolution changes everything Game engine optimization matters Background processes affect CPU load 🧠 Why Bottleneck Calculators Are Only Estimates Most online bottleneck calculators: Use synthetic benchmarks Assume average workloads Ignore real-time variables like Game optimization Driver efficiency RAM speed & latency ⚠️ The Problem:…
