Doom

Resolution Scaling

The measured FPS data for Doom with the AMD Ryzen 7 5700X3D and NVIDIA GeForce RTX 4080 SUPER reveals a pattern where the GPU becomes the dominant constraint as resolution increases. At 1920x1080 with High settings, the combo delivers 278.1 FPS. Moving to 2560x1440 High drops this to 192 FPS, a reduction of roughly 31%. The step to 3840x2160 High yields 100.6 FPS, another 48% reduction from the 1440p figure. This steep decline indicates that the RTX 4080 SUPER is being pushed progressively harder at higher pixel counts, while the Ryzen 7 5700X3D remains capable of feeding frames at lower resolutions.

The scaling from Low to Ultra settings at each resolution reinforces this interpretation. At 1080p Low, the system hits 309.7 FPS, but Ultra caps out at 240.7 FPS — a 22% penalty for the highest preset. At 4K, the spread is wider in percentage terms: Low produces 138.9 FPS while Ultra falls to 82.8 FPS, a 40% drop. The larger relative penalty at 4K suggests that the additional shading and texture work from higher settings disproportionately taxes the GPU when it is already under heavy load from pixel count. The CPU's 96 MB of shared L3 cache and 8-core/16-thread configuration appear sufficient to avoid bottlenecking even at 1080p Low, where the frame rate approaches the 300 FPS range.

A key observation is that the 1080p to 1440p transition at Low settings costs 51.1 FPS (from 309.7 to 258.6), while the 1440p to 4K transition at Low costs 119.7 FPS (from 258.6 to 138.9). The doubling of pixel count from 1440p to 4K produces a much larger absolute FPS loss than the 78% pixel increase from 1080p to 1440p. This non-linear scaling is typical of a GPU-bound scenario at higher resolutions. The data suggests that for competitive play at high refresh rates, 1080p or 1440p are the practical choices, while 4K remains viable for immersive single-player sessions with adjusted settings.

FAQ

How This Combo Ranks

The comboRankInGame field places this configuration at rank 165 out of 1,681 tested combos for Doom. This puts it in the 90th percentile of all combinations, meaning roughly 90% of tested setups trail this one in performance. The ranking reflects the strength of pairing an 8-core Zen 3 CPU with a high-end Ada Lovelace GPU. The Ryzen 7 5700X3D's average benchmark score of 24,673 places it in the 82nd percentile versus all CPUs, with nearest rivals including the Intel Core i7-1360P (0.2% ahead) and AMD Ryzen 5 7600X3D (0.3% ahead). The RTX 4080 SUPER's average score of 53,610 sits in the 88th percentile versus all GPUs, with the AMD Radeon RX 6900 XT just 0.2% behind and the RTX 5070 Ti trailing by 2.9%.

The rank of 165 out of 1,681 is notable because it indicates this combo excels in Doom specifically, not just in synthetic benchmarks. Doom's id Tech engine is known for scaling well across hardware, and the measured data confirms that this pairing extracts strong performance across the board. The CPU's 3DMark results — 6,764 in the 16-thread test and 804 in single-thread — show balanced multicore and single-core capability. The GPU's PassMark G3D score of 34,245 is well above average, placing it among the top tier of graphics cards. Together, these components produce a combo that outperforms the vast majority of tested systems in this particular title.

Measured FPS Breakdown

At 1920x1080, the results span a narrow band of 69 FPS across all settings. Low averages 309.7 FPS, Medium 297.8 FPS, High 278.1 FPS, and Ultra 240.7 FPS. The differences between Low and Medium are small (11.9 FPS), suggesting diminishing returns from the lowest preset. High to Ultra costs 37.4 FPS, a more substantial step that reflects the heavier visual effects in the Ultra preset.

Moving to 2560x1440, the frame rates remain high but show a wider spread. Low averages 258.6 FPS, Medium 224.9 FPS, High 192 FPS, and Ultra 154.8 FPS. The gap from Low to Ultra is 103.8 FPS, nearly double the 1080p spread. At this resolution, the GPU's workload increases noticeably, and the settings choices have a more pronounced impact on achievable frame rates.

At 3840x2160, the data reveals the largest relative differences. Low delivers 138.9 FPS, Medium 122.2 FPS, High 100.6 FPS, and Ultra 82.8 FPS. The step from High to Ultra costs 17.8 FPS, while Low to Medium costs 16.7 FPS. The Ultra preset at 4K is the only measured configuration that drops below 100 FPS, which may matter for displays with 120 Hz or higher refresh rates. Across all resolutions, the ordering is consistent: Low > Medium > High > Ultra, with no anomalies or unexpected inversions.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER serves as the primary performance driver in this combo, particularly at higher resolutions and settings. Its 16 GB of GDDR6X memory on a 256-bit bus provides 736.3 GB/s of bandwidth, which is ample for Doom's texture and geometry demands at 4K. The GPU's boost clock of 2550 MHz (base 2295 MHz) represents a modest overclock headroom over the reference design, and the 10,240 shading units handle the game's compute load efficiently.

The GPU's benchmark scores corroborate its in-game performance. The PassMark G3D score of 34,245 places it in the 88th percentile versus all GPUs, and its 3DMark Steel Nomad DX12 score of 6,600 indicates strong DirectX 12 capability. The nearest rivals — the RX 6900 XT (0.2% behind) and Radeon Pro W6600M (0.4% behind) — highlight how close the top tier of GPUs is in synthetic tests. However, in Doom specifically, the RTX 4080 SUPER's combination of rasterization throughput and memory bandwidth yields consistent performance across all measured settings.

The GPU's 320 W TDP and triple-slot cooler suggest it is designed for sustained high load, which aligns with the frame rates observed at 4K Ultra. The 52.22 TFLOPS of FP32 performance provides ample compute for the game's lighting and particle effects. At 1080p, the GPU is likely underutilized in some settings, as evidenced by the relatively small FPS differences between Low and Medium. At 4K, the GPU becomes the clear bottleneck, with the CPU's 8 cores and 16 threads providing sufficient instruction throughput to avoid limiting the graphics pipeline.

Settings Recommendations

For users prioritizing maximum frame rates at 1920x1080, the Low preset at 309.7 FPS offers headroom for high-refresh-rate displays, but the Medium preset at 297.8 FPS provides a better balance of visual quality and performance, with only a 3.8% FPS penalty. High at 278.1 FPS remains viable for 144 Hz monitors, while Ultra at 240.7 FPS still exceeds most display refresh rates.

At 2560x1440, the Medium preset at 224.9 FPS is the recommended starting point, as it delivers smooth gameplay on 144 Hz and 165 Hz panels. High at 192 FPS is a solid choice for 165 Hz displays, while Ultra at 154.8 FPS remains usable for 144 Hz monitors but leaves little margin for frame time spikes. Low at 258.6 FPS is only necessary for 240 Hz panels where every frame counts.

At 3840x2160, the choice depends on the display's refresh rate. Medium at 122.2 FPS is suitable for 120 Hz TVs and monitors, offering a good compromise between visual fidelity and smoothness. High at 100.6 FPS works for 100 Hz displays but may show occasional dips below the refresh threshold. Ultra at 82.8 FPS is best reserved for 60 Hz displays or for players who prioritize image quality over frame rate. Low at 138.9 FPS is the only 4K setting that comfortably exceeds 120 FPS, making it the choice for high-refresh 4K panels despite the visual trade-offs.

The data shows that the Medium preset offers the most consistent experience across all three resolutions, with frame rates of 297.8, 224.9, and 122.2 FPS respectively. This preset avoids the visual compromises of Low while not incurring the steep performance cost of Ultra. For most users, Medium or High will provide the best measured experience depending on their display's refresh rate and resolution.
