Doom

Resolution Scaling

The measured FPS data for Doom with the AMD Ryzen 7 5800X3D and NVIDIA GeForce RTX 4090 reveals a clear scaling pattern as resolution increases. At 1920x1080 with High settings, the combo produces an average of 304.8 FPS. Moving to 2560x1440 at the same settings drops the average to 210.5 FPS, a reduction of approximately 31%. At 3840x2160, the average falls further to 112.8 FPS, representing a roughly 63% decline from the 1080p figure.

This scaling profile is instructive about where the bottleneck sits. The drop from 1080p to 1440p is steep, but the drop from 1440p to 4K is even steeper in absolute terms: 97.7 FPS lost between 1440p and 4K versus 94.3 FPS lost between 1080p and 1440p. This accelerating decline indicates that the RTX 4090's rendering pipeline becomes increasingly pixel-bound at higher resolutions, with the GPU's shading throughput and memory bandwidth becoming the dominant constraints.

The CPU's role in this scaling is visible in the Low settings row. At 1080p Low, the combo reaches 336.8 FPS; at 1440p Low, it manages 287 FPS; and at 4K Low, it still delivers 156.8 FPS. The relatively modest drop from 1080p Low to 1440p Low (49.8 FPS) suggests that at these lower settings, the CPU has more headroom to feed the GPU. However, the large drop from 1440p Low to 4K Low (130.2 FPS) confirms that the GPU becomes the limiting component as pixel count rises, regardless of the graphics preset.

The data shows a consistent pattern across all settings: the 1080p to 1440p transition typically costs between 30% and 40% of the frame rate, while the 1440p to 4K transition costs between 45% and 55%. This non-linear scaling is characteristic of a system where the GPU is heavily utilized at 1440p and saturated at 4K, while the 5800X3D's 8-core, 16-thread configuration with 96 MB of L3 cache remains capable of keeping up with the GPU's demands even at 1080p.

How This Combo Ranks

Within the benchmark database, this specific combination of the AMD Ryzen 7 5800X3D and NVIDIA GeForce RTX 4090 achieves a combo rank of 78 out of 1681 tested combos in Doom. This places the pairing in the top 5% of all configurations tested for this title, which is notable given the large field of competing hardware combinations.

The rank reflects the synergy between the two components. The CPU's average benchmark score of 26574 places it at the 83rd percentile among all CPUs, with nearest rivals including the AMD EPYC 8024P (deltaPct 0.1), Intel Core i9-11900K (deltaPct 0.1), AMD Ryzen 5 7600 (deltaPct -0.2), and Intel Core i9-12900HK (deltaPct -0.4). These deltas are all within 0.4%, indicating that the 5800X3D's processing performance is tightly clustered with several other strong CPUs.

On the GPU side, the RTX 4090's average benchmark score of 66473 places it at the 91st percentile among all GPUs. Its nearest rivals are the NVIDIA Tesla T4 (deltaPct -0.4), NVIDIA Tesla P40 (deltaPct 0.5), AMD Radeon Pro Vega 56 (deltaPct -0.9), and NVIDIA Quadro P6000 (deltaPct -1.3). These are professional and workstation-oriented cards, which underscores the consumer-level performance of the 4090 in this database context.

The combo rank of 78 out of 1681 suggests that while the individual components are both high-performers, there are still 77 combinations that achieve higher average frame rates in Doom. This is plausible given that the game is from 2016 and may not fully exploit the latest hardware features, but the rank still indicates that this pairing is among the fastest for this title.

GPU Role

The NVIDIA GeForce RTX 4090 brings substantial resources to this pairing. Its 24 GB of GDDR6X memory operates across a 384-bit bus, yielding a bandwidth of 1.01 TB/s. The memory clock is set at 1313 MHz with 21 Gbps effective. The GPU's base clock is 2235 MHz, with a boost clock of 2520 MHz.

The 4090's architecture, Ada Lovelace, is built on a 5 nm process at TSMC, integrating 76,300 million transistors on a 609 mm² die. The GPU contains 16384 shading units, 512 texture mapping units, and 176 render output units. Its compute capabilities include 82.58 TFLOPS for both FP32 and FP16, with texture rate of 1,290.2 GTexel/s and pixel rate of 443.5 GPixel/s.

In Doom, these specifications translate to the measured frame rates. The 4K Ultra result of 91.8 FPS shows that even at maximum settings, the GPU can maintain near-90 FPS at 4K. The 4K High result of 112.8 FPS and 4K Medium of 137.6 FPS demonstrate that the 4090 has headroom for higher refresh rates on high-resolution displays.

The VRAM capacity is relevant for this game's texture handling, though Doom's 2016 engine does not typically require anywhere near 24 GB even at 4K. The memory bandwidth of 1.01 TB/s ensures that texture streaming at high resolutions does not become a constraint, which is consistent with the observed scaling where the GPU's compute and pixel throughput, rather than memory bandwidth, appear to govern performance drops.

The 4090's percentile rank of 91 among all GPUs supports the notion that it is a top-tier consumer card. Its nearest rival deltas are all negative, meaning the 4090 outperforms the Tesla T4, Tesla P40, Radeon Pro Vega 56, and Quadro P6000 by 0.4% to 1.3% in average benchmark score.

Settings Recommendations

The measured data provides a clear picture of how the four presets — Low, Medium, High, and Ultra — affect performance at each resolution. The recommendation for the best experience per the measured rows depends on the target display resolution and refresh rate.

At 1920x1080, all presets deliver well above 200 FPS. The Low preset yields 336.8 FPS, Medium yields 323.7 FPS, High yields 304.8 FPS, and Ultra yields 269.5 FPS. The gap between Low and Ultra is 67.3 FPS, but even Ultra remains substantially above 240 Hz refresh rates. For a 1080p display with a 240 Hz or 360 Hz panel, the High or Ultra preset would provide a smoother visual experience while still maintaining very high frame rates. The difference between High and Ultra is 35.3 FPS, which is noticeable but not dramatic.

At 2560x1440, the situation changes. Low yields 287 FPS, Medium 251.5 FPS, High 210.5 FPS, and Ultra 171.1 FPS. For a 1440p display at 144 Hz, the Ultra preset provides 171.1 FPS, which exceeds the refresh rate with headroom. The High preset at 210.5 FPS also comfortably exceeds 144 Hz. For 240 Hz 1440p panels, the Low preset at 287 FPS or Medium at 251.5 FPS would be necessary to fully saturate the display.

At 3840x2160, the trade-off is more pronounced. Ultra yields 91.8 FPS, High yields 112.8 FPS, Medium yields 137.6 FPS, and Low yields 156.8 FPS. For a 4K display at 60 Hz, the Ultra preset is sufficient, as 91.8 FPS exceeds 60 FPS. For 4K 120 Hz panels, the Medium preset at 137.6 FPS or High at 112.8 FPS would be required. The Low preset at 156.8 FPS is the only option that approaches 144 Hz at 4K, though it sacrifices visual fidelity.

The data indicates that the High preset offers the best balance of visual quality and performance across all three resolutions. At 1080p it provides 304.8 FPS, at 1440p 210.5 FPS, and at 4K 112.8 FPS. These figures are consistently above the refresh rates of most mainstream displays while still providing better image quality than Medium or Low.

Measured FPS Breakdown

The complete measured FPS data for this combo in Doom is as follows:

At 3840x2160, the average frame rates are 91.8 FPS on Ultra, 112.8 FPS on High, 137.6 FPS on Medium, and 156.8 FPS on Low. The spread between the lowest and highest preset is 65 FPS. The progression from Ultra to Low is incremental: 91.8 to 112.8 (a 21 FPS gain), 112.8 to 137.6 (a 24.8 FPS gain), and 137.6 to 156.8 (a 19.2 FPS gain). This relatively even spacing suggests that each preset level imposes a similar additional load on the GPU at 4K.

At 2560x1440, the averages are 171.1 FPS on Ultra, 210.5 FPS on High, 251.5 FPS on Medium, and 287 FPS on Low. The total spread is 115.9 FPS. The increments are 39.4 FPS from Ultra to High, 41 FPS from High to Medium, and 35.5 FPS from Medium to Low. The larger absolute differences compared to 4K indicate that the GPU has more headroom at this resolution, allowing each preset change to have a bigger impact on frame rate.

At 1920x1080, the averages are 269.5 FPS on Ultra, 304.8 FPS on High, 323.7 FPS on Medium, and 336.8 FPS on Low. The total spread is 67.3 FPS, which is smaller than the 1440p spread. The increments are 35.3 FPS from Ultra to High, 18.9 FPS from High to Medium, and 13.1 FPS from Medium to Low. The diminishing returns at higher presets suggest that the CPU or engine-level constraints begin to limit the benefits of lowering settings at 1080p.

Comparing across resolutions at the same preset, the Ultra setting shows the largest absolute drop from 1080p to 4K: 269.5 to 91.8 FPS, a decrease of 177.7 FPS or roughly 66%. The Low setting shows a smaller but still significant drop: 336.8 to 156.8 FPS, a decrease of 180 FPS or roughly 53%. The High setting drops from 304.8 to 112.8 FPS, a 63% reduction. The Medium setting drops from 323.7 to 137.6 FPS, a 57% reduction.

The data shows that the RTX 4090 with the 5800X3D is capable of exceeding 90 FPS at 4K Ultra in Doom, and exceeds 300 FPS at 1080p on High settings. The 4K Low result of 156.8 FPS demonstrates that even at the highest resolution, the combo can push frame rates suitable for high-refresh-rate displays when settings are reduced.
