Ryzen 9 7950X + Arc B580 in Kingdom Come: Deliverance II

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, upscaling disabled. CPU ceiling measured at 1080p, highest settings (TechPowerUp CPU suite), RTX 5090.

1080p

Strong GPU limit

Expected frame rate: 79–79 fps (measured range across sources).

CPU Ryzen 9 7950Xceiling ~182 fps on its own

GPU Arc B580ceiling ~79 fps on its own

The GPU side is lower by about 56.7%: 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

Strong GPU limit

Expected frame rate: 56–56 fps (measured range across sources).

CPU Ryzen 9 7950Xceiling ~182 fps on its own

GPU Arc B580ceiling ~56 fps on its own

The GPU side is lower by about 68.9%: 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: MEDIUM — based on 2 source measurements for these two parts.

4K

Strong GPU limit

Expected frame rate: 32–32 fps (measured range across sources).

CPU Ryzen 9 7950Xceiling ~182 fps on its own

GPU Arc B580ceiling ~32 fps on its own

The GPU side is lower by about 82.5%: 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 2 source measurements for these two parts.
