Measures architectural CPU-GPU balance variance. Real-world gaming varies across game engines, scenes, and background load — treat small differences as noise, not signal.

Workload Verdict: GPU Bottleneck Detected

High Confidence

Meaningful GPU bottleneck detected at 1440p (144Hz). The graphics card is heavily bound by visual demands while the CPU has ample spare headroom.

At 1440p / 144Hz, this system is operating with an active GPU limiting factor (21%). A GPU limiting factor is standard and desirable for gaming: your processor keeps the GPU fully fed with frames, producing consistent frametimes with zero micro-stutter.

How was this 0% computed?

This percentage is an estimate, not a live measurement of your games. It is the scaled gap between CPU pressure and GPU pressure at 1440p / 144Hz under your selected workload profile.

CPU pressure combines the CPU Capability Index (84), the workload CPU weight (1.00), and the refresh demand factor (2.26).

GPU pressure combines the GPU Compute Index (57), the workload GPU weight (1.20), and the resolution load factor (1.00).

The weighting scheme is published openly in the "How Our Calculation Works" section on the homepage, alongside its peer-reviewed research basis and stated limitations.

Validation: tested against 16 real-world CPU benchmark pairings (GeForce RTX 4090, 1080p, 5-game suite, Benchmark.pl data) — the model identified the correct limiting side in 87.5% of pairings, and pairings it rated as more CPU-limited showed proportionally less measured headroom (rank correlation 0.85). Scope: one GPU, one resolution, 16 pairings — preliminary evidence, not proof.

Summary of the limiting factor.

GPU Ceiling Detected (> 20% Range)

Noticeable Variance

The graphics card operates near peak saturation at 1440p.

The graphics card reaches full rasterization and shader utilization first. This is the optimal state for AAA visual fidelity, delivering smooth and predictable frame delivery.

Explanation

What does this actually mean?

At 1440p and 144Hz, this estimate models a targeted performance scenario for your selected hardware. The visual or compute demand of 1440p is heavy enough that the GPU reaches its limit before the CPU does. Suggestion: Lowering visual settings, reducing render resolution, or using image upscaling where supported can help recover performance.

Practical Recommendations

Resolution Strategy

•1080p Competitive: Ensure your CPU is strong. This resolution relies heavily on processor speed for high framerates.
•1440p / 4K Gaming: Shift load to the GPU. If you have a CPU bottleneck, increasing resolution can actually make gameplay smoother by balancing the pacing.

Performance Analysis Summary

When pairing these two components at 1440p, shader and rasterization demand fully saturates the GeForce GTX 1660, while the AMD Ryzen 7 7800X3D operates with comfortable headroom (> 20% range).

Because your processor has ample headroom, frame pacing remains remarkably uniform. To increase framerates at this resolution, consider enabling DLSS, FSR, or lowering demanding post-processing effects.

Real-world utilization varies across game engines, scenes, and background load — treat small differences as noise, not signal.

VRAM Headroom: The GeForce GTX 1660 features 6GB of VRAM. At resolutions higher than 1080p, demanding modern titles may saturate this buffer, leading to texture swapping and frame pacing dips.

Frequently Asked Questions

Why does this build show this bottleneck result?

This build pair shows a result because the GeForce GTX 1660 reaches its limit first at 1440p/144Hz. In AAA Gaming scenarios, this component determines your maximum performance ceiling.

What does an 21% bottleneck mean?

An 21% bottleneck is classified under our canonical scale as a Bottleneck Detected (>20%). It indicates that one component waits on the other for approximately 21% of computation cycles during peak load, determining system equilibrium.

How do resolution and refresh rate affect bottlenecks?

Lower resolutions (like 1080p) and high refresh rates increase pressure on the CPU to prepare frames quickly. Higher resolutions (like 4K) shift the heavy lifting to the GPU for rendering. Adjusting these balances the load.

What should I upgrade first for this build?

Your GeForce GTX 1660 is the limiting factor. Upgrading your graphics card or lowering game settings/resolution will yield the biggest performance gains.

Are bottleneck scores exact?

Use these scores as a guide. Results are estimates; real performance varies by game, settings, drivers, RAM, and thermals. Always verify with real-world benchmarks for your specific titles.
