Ryzen 9 9900X3D + RTX 4090 in Kingdom Come: Deliverance II

Neither a measured verdict nor a direct benchmark covers every figure on this page, so the pair figures below are labelled estimates: calculated from this game's measured results (the measured CPU ceilings and GPU results on the Kingdom Come: Deliverance II benchmarks page), each with its confidence level and the measured parts it is interpolated between. Estimates are badged and styled differently from measured verdicts, and are never presented as measurements. 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 Estimate — not a measurement

Estimated: Balanced pairing

Estimated frame rate: ~156–207 fps (calculated range, not a measured one).

CPU Ryzen 9 9900X3Destimated ceiling ~156–244 fps
GPU RTX 4090delivers ~207 fps in this game at 1080p (measured)

On the estimated figures, the CPU ceiling and the GPU's delivered rate sit within 3.6% of each other — neither part wastes much of the other. The gap is calculated 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.

Estimate — calculated from 13 measured results in this game, not a direct measurement. Confidence: LOW. The CPU figure is interpolated between Core Ultra 9 285K and Ryzen 9 9950X — the nearest measured CPUs in this game. If reviewers publish a benchmark for the estimated part, a measured verdict replaces this estimate. How estimates work.

1440p Estimate — not a measurement

Estimated: Mild GPU limit

Estimated frame rate: ~156–159 fps (calculated range, not a measured one).

CPU Ryzen 9 9900X3Destimated ceiling ~156–244 fps
GPU RTX 4090delivers ~159 fps in this game at 1440p (measured)

On the estimated figures, the GPU side is lower by about 20.5% in this game at 1440p. The math, from the two figures above: the pair runs at the lower one (~159 fps), and the gap to the faster side is (200 − 159) ÷ 200 ≈ 20.5% of the faster side's output. That percentage belongs to this game, this resolution and these settings only — no universal bottleneck percentage exists for a pair of parts.

That range justifies a 144 Hz monitor in this game.

Estimate — calculated from 13 measured results in this game, not a direct measurement. Confidence: LOW. The CPU figure is interpolated between Core Ultra 9 285K and Ryzen 9 9950X — the nearest measured CPUs in this game. If reviewers publish a benchmark for the estimated part, a measured verdict replaces this estimate. How estimates work.

4K Estimate — not a measurement

Estimated: Strong GPU limit

Estimated frame rate: ~89–89 fps (calculated range, not a measured one).

CPU Ryzen 9 9900X3Destimated ceiling ~156–244 fps
GPU RTX 4090delivers ~89 fps in this game at 4K (measured)

On the estimated figures, the GPU side is lower by about 55.3% in this game at 4K. The math, from the two figures above: the pair runs at the lower one (~89 fps), and the gap to the faster side is (200 − 89) ÷ 200 ≈ 55.3% of the faster side's output. That percentage belongs to this game, this resolution and these settings only — no universal bottleneck percentage exists for a pair of parts.

That range suits a 60 Hz monitor; a high-refresh panel would be underused in this game.

Estimate — calculated from 13 measured results in this game, not a direct measurement. Confidence: MEDIUM. The CPU figure is interpolated between Core Ultra 9 285K and Ryzen 9 9950X — the nearest measured CPUs in this game. If reviewers publish a benchmark for the estimated part, a measured verdict replaces this estimate. How estimates work.

No GPU measured in this game at 1440p fully clears this CPU - the strongest measured option:

The pairing figure these options are compared against is the estimate in the card above; every option listed is a measured part.
