Why does this build show this bottleneck result?

This build pair shows a result because the Radeon RX 6800 reaches its limit first at 4K/60Hz. In AAA Gaming scenarios, this component determines your maximum performance ceiling.

What does a 12% bottleneck mean?

A 12% bottleneck is classified under our canonical scale as a Moderate Variance (10–20%). It indicates that one component waits on the other for approximately 12% 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 Radeon RX 6800 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.

Workload Verdict: Moderate GPU Limitation

High Confidence

At 4K (60Hz), the graphics card is working significantly harder than the CPU. Lowering heavy visual presets can reduce GPU load. DLSS/FSR Quality can raise FPS versus native rendering at the same output resolution; the gain depends on the game and hardware.

At 4K / 60Hz, this system is operating with an active GPU limiting factor (12%). 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 4K / 60Hz under your selected workload profile.

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

GPU pressure combines the GPU Compute Index (73), the workload GPU weight (1.20), and the resolution load factor (1.30).

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.

Explanation

What does this actually mean?

At 4K and 60Hz, this estimate models a targeted performance scenario for your selected hardware. The visual or compute demand of 4K 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.

•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

The graphical demands of 4K push the Radeon RX 6800 to near-peak utilization (estimated 10–20% GPU ceiling), which is ideal for delivering smooth, consistent frame delivery in AAA titles.

This configuration operates in a healthy visual ceiling. The processor will not restrict frame times, and the graphics card dictates overall visual throughput.

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

4K Fidelity Report

4K Bottleneck Severity

At 4K, the GPU workload is extreme. Our pressure analysis shows that the Radeon RX 6800 is the primary performance factor. Even with this power, you may need to use upscaling (DLSS/FSR) for stable path-tracing or ultra settings.
