Ryzen 5 2600 + RTX 4070 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

Balanced pairing

Expected frame rate: 46–67 fps (measured range across sources).

CPU Ryzen 5 2600ceiling ~67 fps on its own

GPU RTX 4070ceiling ~46–87 fps on its own

The two measured ceilings sit within 1.2% of each other — neither part wastes much of the other.

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.

1440p

Mild GPU limit

Expected frame rate: 38–67 fps (measured range across sources).

CPU Ryzen 5 2600ceiling ~67 fps on its own

GPU RTX 4070ceiling ~38–70 fps on its own

The GPU side is lower by about 19.6%: 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: LOW — based on 3 source measurements for these two parts.

4K

Strong GPU limit

Expected frame rate: 24–44 fps (measured range across sources).

CPU Ryzen 5 2600ceiling ~67 fps on its own

GPU RTX 4070ceiling ~24–44 fps on its own

The GPU side is lower by about 49.2%: 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.
