Ryzen 7 2700 + RTX 4090 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 CPU limit

Expected frame rate: 54–75 fps (measured range across sources).

CPU Ryzen 7 2700ceiling ~54–75 fps on its own

GPU RTX 4090ceiling ~93–131 fps on its own

The CPU side is lower by about 42.5%: 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 4 source measurements for these two parts.

1440p

Mild CPU limit

Expected frame rate: 54–75 fps (measured range across sources).

CPU Ryzen 7 2700ceiling ~54–75 fps on its own

GPU RTX 4090ceiling ~78–114 fps on its own

The CPU side is lower by about 32.9%: 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 4 source measurements for these two parts.

4K

Balanced pairing

Expected frame rate: 54–75 fps (measured range across sources).

CPU Ryzen 7 2700ceiling ~54–75 fps on its own

GPU RTX 4090ceiling ~54–84 fps on its own

The two measured ceilings sit within 6.5% 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 4 source measurements for these two parts.
