GoKawiilExplainer: Online bottleneck calculators promise quick PC diagnosis but lack accuracy
A technical explainer describes how a system bottleneck occurs when one PC component, such as a CPU or GPU, limits the performance of the rest of the system, which can be identified through stress tests. It also covers bottleneck calculator tools, which estimate hardware mismatches without requiring a full stress test, though the explainer notes these tools often fail to capture how a system actually behaves under load.
