Core i9-14900 vs GeForce RTX 5080 — Bottleneck Analysis

This pairing of the Intel Core i9-14900 (54,000 PassMark) with the NVIDIA GeForce RTX 5080 (28,000 G3D Mark) is analyzed against three target resolutions. Switch resolutions above to see how the balance shifts — at 1080p the CPU has more pressure on it; at 4K the GPU does most of the work.

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
