Comprendre les Goulots d'Étranglement Matériels

Un goulot d'étranglement survient lorsqu'un composant (CPU ou GPU) sature à 100%, empêchant les autres éléments d'atteindre leur plein potentiel.

Impact de la Résolution : Limite CPU vs GPU

En 1080p, la fréquence d'images élevée sollicite fortement le processeur. En 1440p et 4K UHD, la charge bascule lourdement sur la carte graphique.

FAQ Goulot d'Étranglement & FPS PC

关于此项诊断工具、校准步骤及显示器技术标准所需了解的一切。

01.What is a PC bottleneck?
A PC bottleneck occurs when one hardware component (typically the CPU or GPU) limits the overall performance of the system because it reaches 100% utilization while other components wait.
02.How do I know if my PC is CPU bottlenecked or GPU bottlenecked?
If your GPU utilization is below 95% while playing games at uncapped frame rates, your system is likely CPU bottlenecked. High GPU utilization (97-100%) indicates a GPU bottleneck, which is ideal for maximum graphical fidelity.
03.Does resolution affect CPU vs GPU bottlenecking?
Yes. Lower resolutions like 1080p place a higher demand on the CPU to prepare draw calls for high frame rates. Higher resolutions like 4K shift the workload heavily to the GPU due to rendering 8.3 million pixels per frame.
04.Is 100% GPU utilization good for gaming?
Yes, 95% to 100% GPU utilization is optimal. It means your graphics card is working at peak capacity to render maximum visual quality and frame rates without being held back by the processor.
05.Can RAM speed cause a CPU bottleneck?
Slow RAM speed or single-channel memory configurations can starve the CPU of data, artificially increasing CPU draw call delays and low 1% frame time spikes.
06.What is a bottleneck percentage score?
A bottleneck percentage estimates the performance disparity between your CPU and GPU for a given resolution. A score below 10% indicates a well-balanced system.
07.How do I fix a CPU bottleneck?
You can fix a CPU bottleneck by increasing game resolution, enabling ray tracing or higher graphic presets to shift load to the GPU, capping frame rates, or upgrading your CPU.
08.How do I fix a GPU bottleneck?
To reduce a GPU bottleneck, lower resolution or demanding graphics settings like shadows and volumetric lighting, or enable AI upscaling technologies like DLSS, FSR, or XeSS.
09.Does DLSS or FSR reduce CPU bottlenecking?
No. Upscaling technologies like DLSS and FSR render games at lower internal resolutions, which increases frame rates and shifts more work to the CPU, potentially increasing CPU bottlenecking if the CPU is weak.
10.Does V-Sync affect component bottleneck measurements?
Yes. V-Sync or frame rate limiters cap your FPS to match your display refresh rate, reducing component utilization below 100% and preventing natural bottleneck detection.
