Core i9-13900K + RTX 4070 in Baldur's Gate 3

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, DX11, native rendering, no upscaling, no frame generation. CPU ceiling measured at 1080p, Medium preset (reviewers' CPU-isolation method), flagship GPU, Act III.

1080p

Mild CPU limit

Expected frame rate: 122–122 fps (measured range across sources).

CPU Core i9-13900Kceiling ~122 fps on its own
GPU RTX 4070ceiling ~163 fps on its own

The CPU side is lower by about 25.1%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

That range justifies a 144 Hz monitor in this game.

Confidence: MEDIUM — based on 2 source measurements for these two parts.

1440p

Balanced pairing

Expected frame rate: 122–122 fps (measured range across sources).

CPU Core i9-13900Kceiling ~122 fps on its own
GPU RTX 4070ceiling ~122 fps on its own

The two measured ceilings sit within 0.4% of each other — neither part wastes much of the other.

That range justifies a 144 Hz monitor in this game.

Confidence: MEDIUM — based on 2 source measurements for these two parts.

4K

Strong GPU limit

Expected frame rate: 68–83 fps (measured range across sources).

CPU Core i9-13900Kceiling ~122 fps on its own
GPU RTX 4070ceiling ~68–83 fps on its own

The GPU side is lower by about 38.3%: 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.
