Ryzen 5 5600X + RTX 5090 in Kingdom Come: Deliverance II

Every figure below is a measurement aggregated from published review charts — the CPU's frame-rate ceiling and the frame rate the GPU delivers in this game, combined. The CPU figure is the highest frame rate that CPU sustained in this game with a flagship GPU installed — past that frame rate, the CPU is the limit. Settings: Ultra preset, upscaling disabled. CPU ceiling measured at 1080p, highest settings (TechPowerUp CPU suite), RTX 5090; Ryzen 5 5600X from Gamers Nexus at its Medium CPU-isolation preset.

1080p

Mild CPU limit

Expected frame rate: 172–172 fps (measured range across sources).

CPU Ryzen 5 5600Xceiling ~172 fps on its own
GPU RTX 5090delivers ~225 fps in this game at 1080p

The CPU side is lower by about 23.5% in this game at 1080p. The math, from the two measured figures above: the pair runs at the lower one (~172 fps), and the gap to the faster side is (225 − 172) ÷ 225 ≈ 23.5% of the faster side's output. That percentage belongs to this game, this resolution and these settings only — the same two parts score differently in another game, which is why no universal bottleneck percentage exists for a pair of parts. Upgrading the faster part alone would not raise the frame rate.

That range feeds a 165 Hz or faster monitor — this is high-refresh territory in this game.

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

1440p

Balanced pairing

Expected frame rate: 172–172 fps (measured range across sources).

CPU Ryzen 5 5600Xceiling ~172 fps on its own
GPU RTX 5090delivers ~186 fps in this game at 1440p

The CPU ceiling and the GPU's delivered rate sit within 7.2% of each other — neither part wastes much of the other. The gap is measured between the two figures above: (faster − slower) ÷ faster.

That range feeds a 165 Hz or faster monitor — this is high-refresh territory in this game.

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

4K

Mild GPU limit

Expected frame rate: 116–116 fps (measured range across sources).

CPU Ryzen 5 5600Xceiling ~172 fps on its own
GPU RTX 5090delivers ~116 fps in this game at 4K

The GPU side is lower by about 32.3% in this game at 4K. The math, from the two measured figures above: the pair runs at the lower one (~116 fps), and the gap to the faster side is (172 − 116) ÷ 172 ≈ 32.3% of the faster side's output. That percentage belongs to this game, this resolution and these settings only — the same two parts score differently in another game, which is why no universal bottleneck percentage exists for a pair of parts. Upgrading the faster part alone would not raise the frame rate.

That range justifies a 144 Hz monitor in this game.

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