Understanding Your Results

Identifies whether a system is CPU-bound, GPU-bound, or Well-Balanced across 1080p, 1440p, and 4K resolutions with practical upgrade guidance.

Practical Guidance & Next Steps

At 4K, almost all gaming workloads are GPU-bound. At 1080p high FPS esports, the CPU draw-call rate determines performance limits.

What is this?

A PC hardware diagnostic tool that analyzes CPU and GPU pairing balance across various display resolutions.

How does it work?

1. Select your processor (CPU) and graphics card (GPU). 2. Choose your primary gaming resolution (1080p, 1440p, or 4K). 3. View bottleneck percentage score and detailed architectural pairing advice.

Why use it?

Helps you invest upgrade money wisely in the component that actually holds back your gaming performance.

Technical Scope & Calculation Limitations

Estimates architectural balance across AAA games. Game engine optimization and RAM speed also influence real-world frame rates.

Frequently Asked Questions

No. In fact, a GPU bottleneck is the ideal scenario for PC gaming, ensuring your graphics card is 99-100% utilized to produce maximum visual fidelity.
