Ryzen Threadripper 9970X vs Radeon RX 9070 XT — Bottleneck Analysis

This pairing of the AMD Ryzen Threadripper 9970X (135,000 PassMark) with the AMD Radeon RX 9070 XT (21,000 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
