Ryzen 5 5600 + RTX 4080 Super 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: 77–77 fps (measured range across sources).

CPU Ryzen 5 5600ceiling ~77 fps on its own
GPU RTX 4080 Superceiling ~121 fps on its own

The CPU side is lower by about 36.1%: 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 2 source measurements for these two parts.

1440p

Mild CPU limit

Expected frame rate: 77–77 fps (measured range across sources).

CPU Ryzen 5 5600ceiling ~77 fps on its own
GPU RTX 4080 Superceiling ~101 fps on its own

The CPU side is lower by about 23.6%: 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 2 source measurements for these two parts.

4K

Balanced pairing

Expected frame rate: 70–70 fps (measured range across sources).

CPU Ryzen 5 5600ceiling ~77 fps on its own
GPU RTX 4080 Superceiling ~70 fps on its own

The two measured ceilings sit within 10.1% 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: MEDIUM — based on 2 source measurements for these two parts.
