Ryzen 9 7950X3D + RTX 4070 Super: bottleneck check
GPU-limited at 1440p. GPU-bound (normal).
The RTX 4070 Super is the part working hardest at 1440p, which is what you want. The Ryzen 9 7950X3D keeps about 24% in reserve.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | GPU | 17% | balanced |
| 1440p | GPU | 24% | GPU-bound (normal) |
| 4K | GPU | 40% | GPU-bound (normal) |
The RTX 4070 Super is the limiting part at every resolution, which is the healthy direction, and the gap is small enough that neither part is wasted. Upgrade the GPU first when you want more frames.
