Bottleneck Analysis

Pick a CPU and GPU to see bottleneck analysis.

How it works

We compare the PassMark CPU Mark against the GPU's G3D Mark, calibrated for your target resolution. Higher resolution = more GPU work, so the ideal CPU/GPU ratio shifts upward. We benchmark against reference balanced builds to set the bands: under 10% imbalance is "balanced", 10-25% is mild, 25-50% is moderate, over 50% is severe.

What do the severity levels mean?

Balanced (<10%) — both parts well-matched, no upgrade needed
Mild (10–25%) — small imbalance, performance still strong
Moderate (25–50%) — noticeable bottleneck, upgrade recommended
Severe (>50%) — major imbalance, one part is wasted
