Core Ultra 9 285K + Intel Arc B570 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: 51–51 fps (measured range across sources).

CPU Core Ultra 9 285Kceiling ~154 fps on its own
GPU Intel Arc B570ceiling ~51 fps on its own

The GPU side is lower by about 66.7%: 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.

1440p

Strong GPU limit

Expected frame rate: 40–40 fps (measured range across sources).

CPU Core Ultra 9 285Kceiling ~154 fps on its own
GPU Intel Arc B570ceiling ~40 fps on its own

The GPU side is lower by about 73.7%: 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.

4K

Strong GPU limit

Expected frame rate: 26–26 fps (measured range across sources).

CPU Core Ultra 9 285Kceiling ~154 fps on its own
GPU Intel Arc B570ceiling ~26 fps on its own

The GPU side is lower by about 83.1%: 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 2 source measurements for these two parts.
