Doom

The AMD Ryzen 5 5600 paired with the NVIDIA GeForce RTX 4090 delivers exceptionally high frame rates in Doom, with the data showing that every tested settings preset at every resolution clears the 60 FPS playable threshold by a substantial margin. The measured results place this combination in the top tier of tested systems, though the CPU’s mid-range standing means the RTX 4090 is often doing the heavy lifting to maintain these scores.

Measured FPS Breakdown

At 1920x1080, the combo produces triple-digit averages across all four settings presets. The Low preset yields an average of 340 FPS, which is the highest recorded figure in the entire dataset. Medium follows at 327.8 FPS, while High drops to 306.5 FPS. The most demanding Ultra preset still maintains an average of 266.2 FPS. The spread between Low and Ultra is 73.8 FPS, indicating that even the most aggressive visual settings only reduce performance by roughly 22% relative to the lowest preset.

Moving to 2560x1440, the averages remain far above any refresh-rate concern. Low delivers 290.3 FPS, Medium hits 253.3 FPS, High produces 213.4 FPS, and Ultra settles at 170.4 FPS. The gap between Low and Ultra here is 119.9 FPS, a larger absolute difference than at 1080p, but the relative drop from Low to Ultra is about 41%, reflecting the increased pixel throughput demands.

At 3840x2160, the resolution scaling becomes more pronounced. Low averages 156.3 FPS, Medium drops to 134.6 FPS, High comes in at 117.3 FPS, and Ultra falls to 91.6 FPS. The difference between Low and Ultra at 4K is 64.7 FPS, and the Ultra preset is the only setting that approaches but never breaches the triple-digit mark. Still, 91.6 FPS at Ultra 4K is far beyond the playable threshold.

Notably, the dataset includes only average FPS values, with min and max figures left null across every resolution and preset. This means the analysis relies solely on mean performance, which for a fast-paced FPS like Doom should be interpreted with some caution — frame time consistency and 1% lows are not captured in these numbers.

CPU and GPU Roles

The data reveals a clear shift in component responsibility as resolution increases. At 1920x1080, the average frame rates are extraordinarily high, reaching 340 FPS on Low. These numbers suggest the CPU is the primary limiter, as the RTX 4090’s raw throughput would likely push even higher if the Ryzen 5 5600 could feed it fast enough. The 5600’s benchmark scores — a Cinebench R23 multi-core result of 18309 and a single-core score of 2584 — place it in the 74th percentile of all CPUs, which is respectable but not flagship-tier. The scaling from Low to Ultra at 1080p (340 to 266.2 FPS) shows that GPU load does increase with settings, but the CPU remains a bottleneck at the very top end.

At 2560x1440, the frame rates drop by roughly 15-20% across all presets compared to 1080p. Low goes from 340 to 290.3 FPS, and Ultra from 266.2 to 170.4 FPS. This reduction indicates that the GPU is starting to take on more of the workload, but the absolute numbers remain so high that the CPU still plays a significant role in limiting performance, particularly on the Low and Medium presets where pixel shading is less demanding.

The 3840x2160 results show the GPU becoming the dominant factor. Low drops to 156.3 FPS, a 46% reduction from the 1080p Low figure, while Ultra falls to 91.6 FPS, a 66% reduction from 1080p Ultra. This disproportionate decline at higher settings is the signature of a GPU-bound scenario — the RTX 4090’s 82.58 TFLOPS FP32 compute and 1.01 TB/s memory bandwidth are being saturated by the 4K pixel load, while the CPU’s job of issuing draw calls becomes relatively less important. The RTX 4090’s 88th percentile standing among all GPUs, with an average benchmark score of 60347, supports this interpretation: it is a top-tier part, but the 5600’s more modest CPU percentile means the pairing is unbalanced at lower resolutions.

How This Combo Ranks

The combo ranks 174th out of 3712 tested combinations in Doom, placing it in the top 4.7% of all systems. This rank reflects the measured FPS data, which shows the RTX 4090 delivering near-maximum performance even when paired with a mid-range CPU. The CPU’s nearest rivals in synthetic benchmarks include the Intel Core Ultra 7 258V (0.1% higher average score), AMD Ryzen 5 8500G (0.2% higher), and AMD EPYC 9454P (0.2% higher), all of which are within a rounding error of the 5600’s average score of 20468. This clustering suggests that the 5600 is not leaving significant performance on the table relative to similarly-scoring processors.

The GPU’s nearest rivals tell a similar story. The Intel Arc Pro A60 scores 60326, a 0% delta from the RTX 4090’s 60347 average, while the AMD Radeon Pro Vega 48 trails by 0.3%. The AMD Radeon Pro W6600M scores 61896, which is 2.5% higher, and the AMD Radeon PRO V710 sits 2.9% lower at 58657. These benchmark deltas are synthetic, not game-specific, but they indicate that the RTX 4090 is performing at or near the level of its direct peers.

In Doom specifically, the 174th rank out of 3712 combos means the majority of higher-ranked systems likely feature faster CPUs, but the game’s engine is clearly not CPU-bound enough at the tested resolutions to prevent this combo from achieving excellent results. The 91.6 FPS average at 4K Ultra is a strong indicator that the pairing is well-suited for high-refresh-rate 4K displays.

FAQ

Q: Can this PC run Doom at 4K Ultra settings?

A: Yes. The measured average FPS at 3840x2160 with Ultra settings is 91.6 FPS, which is well above the 60 FPS playable threshold.

Q: What is the highest FPS this combo achieves in Doom?

A: The highest recorded average is 340 FPS, achieved at 1920x1080 with Low settings.

Q: Is the CPU or GPU the bigger bottleneck at 1080p?

A: The data suggests the CPU is the primary limiter at 1920x1080, as frame rates reach 340 FPS on Low and the Ryzen 5 5600’s 74th percentile CPU standing is modest relative to the RTX 4090’s 88th percentile GPU position.

Q: How does the frame rate drop from 1080p to 4K at Ultra settings?

A: At Ultra, the average FPS falls from 266.2 at 1920x1080 to 170.4 at 2560x1440, then to 91.6 at 3840x2160 — a total reduction of 174.6 FPS from 1080p to 4K.

Q: Does the RTX 4090 outperform its nearest rivals in synthetic benchmarks?

A: The RTX 4090’s average benchmark score of 60347 is effectively tied with the Intel Arc Pro A60 (60326, 0% delta) and slightly ahead of the AMD Radeon Pro Vega 48 (60140, 0.3% delta), but behind the AMD Radeon Pro W6600M (61896, -2.5% delta).

Q: What is the least demanding preset that still clears 60 FPS at 4K?

A: All four presets at 3840x2160 clear 60 FPS. The lowest average is 91.6 FPS at Ultra, so even the most demanding setting is not at risk of dropping below the threshold.

Best Settings per Resolution

At 1920x1080, the Ultra preset is the most demanding option that stays at or above 60 FPS, with an average of 266.2 FPS. Since all presets clear the threshold by a wide margin, the recommendation is to use Ultra for the best visual quality without sacrificing playability.

At 2560x1440, Ultra again is the recommended preset, averaging 170.4 FPS. This leaves ample headroom for any refresh-rate display, and the visual fidelity gains from Ultra are worthwhile given the performance surplus.

At 3840x2160, Ultra remains the best choice, with an average of 91.6 FPS. This is the only resolution where the average approaches the triple-digit mark, but 91.6 FPS still provides a smooth experience on most 4K displays. For users prioritizing higher frame rates, dropping to High yields 117.3 FPS, a 25.7 FPS improvement, but the Ultra preset’s 91.6 FPS average is already comfortably above 60.

The Verdict

This PC can definitively run Doom. The verdict by resolution lists every preset — High, Low, Medium, and Ultra — as playable at all three tested resolutions. At 1920x1080, the lowest average across any preset is 266.2 FPS, meaning even the heaviest settings never dip near the 60 FPS threshold. At 2560x1440, the floor is 170.4 FPS on Ultra, again far above the playable mark. At 3840x2160, the Ultra preset delivers 91.6 FPS, which is the weakest result in the dataset but still clears the threshold by over 50%. The combo’s 174th rank out of 3712 tested combinations underscores that this is a high-performing setup, even if the Ryzen 5 5600’s mid-range CPU standing means there is theoretical headroom for a faster processor in CPU-bound scenarios. For Doom specifically, the RTX 4090’s immense GPU power ensures that no resolution or settings preset presents a challenge to maintaining fluid, high-refresh-rate gameplay.
