Ryzen 5 5600X + RX 6800 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

Strong GPU limit

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

CPU Ryzen 5 5600Xceiling ~172 fps on its own

GPU RX 6800delivers ~83 fps in this game at 1080p

The GPU side is lower by about 51.7% in this game at 1080p. The math, from the two measured figures above: the pair runs at the lower one (~83 fps), and the gap to the faster side is (172 − 83) ÷ 172 ≈ 51.7% 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 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: 61–61 fps (measured range across sources).

CPU Ryzen 5 5600Xceiling ~172 fps on its own

GPU RX 6800delivers ~61 fps in this game at 1440p

The GPU side is lower by about 64.5% in this game at 1440p. The math, from the two measured figures above: the pair runs at the lower one (~61 fps), and the gap to the faster side is (172 − 61) ÷ 172 ≈ 64.5% 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 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: 34–34 fps (measured range across sources).

CPU Ryzen 5 5600Xceiling ~172 fps on its own

GPU RX 6800delivers ~34 fps in this game at 4K

The GPU side is lower by about 80.3% in this game at 4K. The math, from the two measured figures above: the pair runs at the lower one (~34 fps), and the gap to the faster side is (172 − 34) ÷ 172 ≈ 80.3% 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 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.
