Ryzen 7 7800X3D + RTX 4080 Super in Starfield

Every figure below is a measurement aggregated from published review charts — the CPU's frame-rate ceiling and the GPU's frame-rate ceiling in this game, combined. Settings: Ultra preset, native rendering, no upscaling, no frame generation. CPU ceiling measured at 1080p, Low preset (reviewers' CPU-isolation method), flagship GPU.

1080p

Mild GPU limit

Expected frame rate: 121–121 fps (measured range across sources).

CPU Ryzen 7 7800X3Dceiling ~124–166 fps on its own
GPU RTX 4080 Superceiling ~121 fps on its own

The GPU side is lower by about 16.5%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

That range justifies a 144 Hz monitor in this game.

Confidence: LOW — based on 3 source measurements for these two parts.

1440p

Mild GPU limit

Expected frame rate: 101–101 fps (measured range across sources).

CPU Ryzen 7 7800X3Dceiling ~124–166 fps on its own
GPU RTX 4080 Superceiling ~101 fps on its own

The GPU side is lower by about 30.2%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

That range suits a 60 Hz monitor; a high-refresh panel would be underused in this game.

Confidence: LOW — based on 3 source measurements for these two parts.

4K

Strong GPU limit

Expected frame rate: 70–70 fps (measured range across sources).

CPU Ryzen 7 7800X3Dceiling ~124–166 fps on its own
GPU RTX 4080 Superceiling ~70 fps on its own

The GPU side is lower by about 52.0%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

That range suits a 60 Hz monitor; a high-refresh panel would be underused in this game.

Confidence: MEDIUM — based on 3 source measurements for these two parts.
