Core i5-13400F + RX 7900 XTX 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

Mild CPU limit

Expected frame rate: 92–92 fps (measured range across sources).

CPU Core i5-13400Fceiling ~92 fps on its own
GPU RX 7900 XTXceiling ~102–129 fps on its own

The CPU side is lower by about 20.0%: 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 3 source measurements for these two parts.

1440p

Balanced pairing

Expected frame rate: 82–92 fps (measured range across sources).

CPU Core i5-13400Fceiling ~92 fps on its own
GPU RX 7900 XTXceiling ~82–110 fps on its own

The two measured ceilings sit within 4.2% 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.

4K

Mild GPU limit

Expected frame rate: 52–75 fps (measured range across sources).

CPU Core i5-13400Fceiling ~92 fps on its own
GPU RX 7900 XTXceiling ~52–75 fps on its own

The GPU side is lower by about 30.9%: 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 3 source measurements for these two parts.
