Core Ultra 9 285K + RTX 2080 Ti 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: 32–56 fps (measured range across sources).

CPU Core Ultra 9 285Kceiling ~154 fps on its own
GPU RTX 2080 Ticeiling ~32–56 fps on its own

The GPU side is lower by about 71.4%: 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 3 source measurements for these two parts.

1440p

Strong GPU limit

Expected frame rate: 27–46 fps (measured range across sources).

CPU Core Ultra 9 285Kceiling ~154 fps on its own
GPU RTX 2080 Ticeiling ~27–46 fps on its own

The GPU side is lower by about 76.1%: 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: 31–31 fps (measured range across sources).

CPU Core Ultra 9 285Kceiling ~154 fps on its own
GPU RTX 2080 Ticeiling ~31 fps on its own

The GPU side is lower by about 79.7%: 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.
