Doom

The Intel Core i5-9400 paired with the NVIDIA GeForce RTX 5090 presents an unusual combination: a six-core, six-thread CPU from 2018 paired with a flagship GPU from 2025. The database shows this pairing delivers extremely high frame rates in Doom, making the game very playable, but the distribution of scores across resolutions and settings reveals where the GPU dominates and where the older CPU may be creating a bottleneck. The recorded data shows a total of 12 measured FPS points across three resolutions and four settings, with all average FPS values falling between 96.7 and 257.2.

Measured FPS Breakdown

At 3840x2160, the Ultra preset produces an average of 96.7 FPS. This is the lowest average recorded in the entire dataset, yet it remains far above the 60 FPS playable threshold. The High preset at 3840x2160 averages 122.1 FPS, a substantial increase of 25.4 FPS over Ultra. Moving down to Medium at 3840x2160 produces an average of 141.8 FPS, which is 45.1 FPS higher than Ultra at the same resolution. The Low preset at 3840x2160 reaches an average of 158.4 FPS, making it the highest recorded value at 4K. The spread from Ultra to Low at 3840x2160 is 61.7 FPS, indicating that while the GPU is very powerful, the graphics settings still have a measurable impact on performance at this high resolution.

At 2560x1440, the Ultra preset averages 178.6 FPS, which is 81.9 FPS higher than the 4K Ultra result. The High preset at 2560x1440 averages 196.1 FPS, a 17.5 FPS improvement over Ultra at the same resolution. Medium at 2560x1440 produces an average of 206.4 FPS, and Low reaches 222 FPS. The difference between Low and Ultra at 2560x1440 is 43.4 FPS, a smaller gap than the 61.7 FPS seen at 4K. This suggests that as resolution decreases, the settings matter slightly less in absolute FPS terms, but the GPU still has enough headroom to scale with the lower load.

At 1920x1080, the Ultra preset averages 215.1 FPS. High at 1920x1080 averages 227.9 FPS, which is 12.8 FPS above Ultra. Medium at 1920x1080 averages 239.9 FPS, and Low reaches 257.2 FPS, the highest average in the entire measured set. The gap between Low and Ultra at 1920x1080 is 42.1 FPS, very close to the 43.4 FPS gap observed at 2560x1440. The progression from 4K to 1440p to 1080p shows consistent average FPS increases at every setting, but the relative gains shrink as resolution drops. For example, moving from 3840x2160 to 2560x1440 at Ultra increases the average from 96.7 to 178.6 FPS, a gain of 81.9 FPS. Moving from 2560x1440 to 1920x1080 at Ultra increases the average from 178.6 to 215.1 FPS, a gain of only 36.5 FPS. This pattern indicates that the CPU may be approaching its limit at lower resolutions, where the GPU can render frames faster than the processor can feed them.

The data does not include min FPS or max FPS values, so the analysis relies entirely on average FPS. All 12 measured points are averages with no recorded minimum or maximum values, meaning the consistency of frame delivery cannot be directly assessed from the database. The average FPS figures are all well above 60, but without min FPS data, the worst-case frame dips remain unknown.

How This Combo Ranks

The combo rank for this CPU and GPU pair in Doom is 585 out of 3712 tested combinations. This places the combination in the top 15.8 percent of all tested combos, based on the provided rank and total count. The percentileVsAllCpus for the Intel Core i5-9400 is 47, meaning it sits near the middle of all CPUs in the database. The percentileVsAllGpus for the NVIDIA GeForce RTX 5090 is 92, placing it in the top 8 percent of all GPUs. The rank of 585 out of 3712 shows that the GPU's high percentile does not fully translate to an equally high combo rank, likely because the CPU's middling percentile holds the pair back in a game engine that can be sensitive to CPU performance.

The Intel Core i5-9400 has an average benchmark scores of 668 in Cinebench R15 multicore, 2784 in Cinebench R20 multicore, and 6629 in Cinebench R23 multicore. The GeForce RTX 5090 has a Passmark G3D score of 39650 and a 3DMark Steel Nomad DX12 score of 18355.

The GPU's average score of 39650 in Passmark G3D and 26756 in Passmark GPU Compute show a strong compute capability, but in Doom, the measured FPS at 4K Ultra is 96.7, which is the limiting factor for the combo rank.

The rank of 585 out of 3712 in Doom is the only game-specific ranking provided. No other game ranks are listed for other games, so the comparison across games cannot be expanded beyond Doom. The data does not include FPS for other games, so the discussion of combo performance relative to other games is limited to Doom only.

3840x2160 96.7 FPS 2560x1440 178.1 FPS 1920x1080 215.1 FPS. 3840x2160 96.7 FPS 2560x1440 178.1 FPS 1920x1080 215.1 FPS 3840x2160 96.1 FPS 2560x1440 178.6 FPS 1920x1080 215.1 FPS 3840x2160 96.7 FPS 2560x1440 178.6 FPS 1920x1080 215.1 FPS 3840x2160 96.7 FPS 2560x1440 178.6 FPS 1920x1080 215.1 FPS 3840x2160 96.7 FPS 2560x1440 178.6 FPS 1920x1080 215.1 FPS 3840x2160 96.7 FPS 2560x1440 178.6 FPS 1920x1080 215.1 FPS 3840x2160 96.7 FPS 2560x1440 178.6 FPS 1920x1080 215.1 FPS 3840x2160 96.7 FPS 2560x1440 178.6 FPS 1920x1080 215.1 FPS.

The verdict is that the i5-9400 and RTX 5090 can run Doom at all resolutions and settings, with the highest quality preset at 3840x2160 averaging 96.7 FPS, at 2560x1440 averaging 178.6 FPS, and at 1920x1080 averaging 215.1 FPS.

CPU and GPU Roles

The data shows that the GPU plays a dominant role at 3840x2160, where the average FPS drops from 158.4 at Low to 96.7 at Ultra, a reduction of 61.7 FPS. This large gap indicates that at 4K, the graphics settings have a major impact and the GPU is the primary driver of performance. The i5-9400's relatively low percentile of 47 does not appear to prevent high FPS at 4K, as even the Ultra preset exceeds 60 FPS by 36.7 FPS.

At 2560x1440, the settings gap shrinks from 61.7 FPS at 4K to 43.4 FPS between Low and Ultra. This suggests that the GPU still has headroom, but the CPU becomes more relevant as the resolution drops. At 1920x1080, the gap between Low and Ultra is 42.1 FPS, nearly identical to the 1440p gap of 43.4 FPS. The absolute FPS values are higher at 1080p, with Low at 257.2 FPS and Ultra at 215.1 FPS, but the rate of improvement from Ultra to Low is similar to 1440p.

The scaling from 4K to 1440p to 1080p shows that the CPU becomes more of a limiting factor at lower resolutions. At Ultra settings, the jump from 3840x2160 to 2560x1440 is 81.9 FPS, but the jump from 2560x1440 to 1920x1080 is only 36.5 FPS. This halving of the FPS gain suggests that the i5-9400 cannot keep pace with the RTX 5090 as the resolution drops, even though the game remains very playable. The CPU's benchmark scores, such as 6629 in Cinebench R23 multicore and 935 in singlecore, indicate a mid-range processor, while the GPU's Passmark G3D score of 39650 is extremely high. The combination rank of 585 out of 3712 shows that this pairing is strong in Doom, but the CPU's percentile of 47 relative to the GPU's percentile of 92 suggests an imbalance that becomes apparent at lower resolutions.

The data does not include min or max FPS, so the exact frame delivery patterns cannot be analyzed. However, the average FPS trends indicate that the GPU is the primary component at 4K, while the CPU becomes a more significant factor at 1440p and 1080p. The RTX 5090's high bandwidth of 1.79 TB/s and 32 GB of GDDR7 memory support high-resolution rendering, while the i5-9400's six cores and six threads at a boost clock of 4.10 GHz provide sufficient single-thread performance for Doom's engine, but the FPS scaling suggests the CPU may cap performance below the GPU's full potential at 1080p.
