Core i5-14600K + RTX 3080 10GB 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

Strong GPU limit

Expected frame rate: 42–82 fps (measured range across sources).

CPU Core i5-14600Kceiling ~149 fps on its own

GPU RTX 3080 10GBceiling ~42–82 fps on its own

The GPU side is lower by about 58.4%: 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.

1440p

Strong GPU limit

Expected frame rate: 35–68 fps (measured range across sources).

CPU Core i5-14600Kceiling ~149 fps on its own

GPU RTX 3080 10GBceiling ~35–68 fps on its own

The GPU side is lower by about 65.6%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

That range sits under a smooth 60 in this game at the tested preset — expect to trade settings for frame rate.

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

4K

Strong GPU limit

Expected frame rate: 46–46 fps (measured range across sources).

CPU Core i5-14600Kceiling ~149 fps on its own

GPU RTX 3080 10GBceiling ~46 fps on its own

The GPU side is lower by about 69.4%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

That range sits under a smooth 60 in this game at the tested preset — expect to trade settings for frame rate.

Confidence: MEDIUM — based on 2 source measurements for these two parts.

No GPU measured in this game at 1440p fully clears this CPU - the strongest measured option:

RTX 5090 — ceiling ~134 fps (still the limiting side, but the highest measured ceiling) · full result
