Doom

The AMD Ryzen 9 5900X and NVIDIA GeForce RTX 4080 SUPER combination delivers exceptional performance in Doom, with benchmark results showing that the system is overwhelmingly GPU-limited at higher resolutions while retaining massive headroom at 1080p. The measured data indicates a highly capable pairing that ranks in the top 8.3% of all tested combinations, though the CPU's 12-core, 24-thread configuration with a 4.80 GHz boost clock proves more than sufficient for this title's demands, even at lower settings where frame rates exceed 360 FPS.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a clear and predictable pattern of GPU-bound scaling. At 1080p with Low settings, the combination achieves 363 FPS on average, which drops to 259 FPS at 1440p and further to 140 FPS at 4K. This represents a 61.4% reduction in frame rate when moving from 1080p to 4K at Low settings, indicating that the rendering load scales dramatically with pixel count, as expected for a GPU-centric workload.

The High settings preset shows similar scaling behavior: 294 FPS at 1080p, 190 FPS at 1440p, and 103 FPS at 4K. The percentage drops are consistent—35.4% from 1080p to 1440p, and another 45.8% from 1440p to 4K. This consistent scaling pattern suggests that the RTX 4080 SUPER's 16 GB of GDDR6X memory and 736.3 GB/s bandwidth are the primary determinants of performance, with the CPU providing ample support throughout.

At Ultra settings, the scaling is even more pronounced: 240 FPS at 1080p, 155 FPS at 1440p, and 84 FPS at 4K. The 4K Ultra result represents a 65% drop from the 1080p Ultra figure, which is the largest relative decline across all settings. This indicates that at the highest quality presets and highest resolution, the GPU is working near its limits, though the 84 FPS average remains highly playable for a fast-paced FPS.

The Medium settings rows provide additional insight through their min/max FPS data. At 4K Medium, the average is 122 FPS with a minimum of 104 and maximum of 140, showing a tight 36 FPS spread. At 1440p Medium, the average rises to 225 FPS with a minimum of 191 and maximum of 259, while 1080p Medium shows 346 FPS average with a minimum of 294 and maximum of 398. The relatively narrow min-to-max ranges, especially at 4K, indicate stable frame pacing without significant CPU-related hitches or GPU thermal throttling.

The data strongly suggests that at 1080p, particularly at Low and Medium settings, the system may be approaching CPU limitations in certain scenes, given that the RTX 4080 SUPER is capable of far higher frame rates than the 363 FPS ceiling observed. However, the Ryzen 9 5900X's strong single-thread performance, evidenced by its 941 3DMark single-thread score and 1527 Cinebench R23 single-core result, keeps the system well above any practical refresh rate threshold.

CPU Role

The AMD Ryzen 9 5900X brings substantial processing power to this combination, featuring 12 cores and 24 threads based on the Zen 3 architecture codenamed Vermeer. With a base clock of 3.70 GHz and a boost clock of 4.80 GHz, the processor demonstrates strong single-threaded performance that is critical for achieving high frame rates in Doom, a game that relies heavily on rapid CPU-GPU communication.

Benchmark data reinforces the CPU's capability. The Cinebench R23 single-core score of 1527 and multi-core score of 16262 indicate balanced performance across both lightly-threaded and fully-parallel workloads. The 3DMark single-thread score of 941 and 2-thread score of 1852 further confirm that the CPU can handle the per-frame processing demands of a high-FPS FPS title without becoming a limiting factor in most scenarios.

The measured FPS data suggests that at 1080p Low settings (363 FPS average), the CPU may be approaching its practical limit for this game's engine. However, the fact that 1080p Medium achieves 346 FPS and 1080p High achieves 294 FPS shows that even when GPU load increases, the CPU maintains frame rates above 290 FPS. At 1440p and 4K, the GPU clearly becomes the dominant bottleneck, as evidenced by the consistent frame rate drops across all settings presets.

The CPU's 64 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide adequate data throughput for the game's assets, though the GPU's 736.3 GB/s memory bandwidth is far higher, underscoring the different roles each component plays. The 7 nm process node and 8,300 million transistors contribute to the CPU's efficiency, though thermal and power characteristics are secondary considerations given the game's performance profile.

Settings Recommendations

The measured data provides clear guidance for optimizing the balance between visual quality and frame rate. For 4K displays, the Medium preset offers the best compromise, delivering 122 FPS average with a minimum of 104 FPS. This represents an 18.4% improvement over High settings (103 FPS) while maintaining a minimum frame rate that never dips below 100 FPS, which is crucial for maintaining smooth motion in intense combat scenarios.

At 1440p, the High preset is the recommended choice, achieving 190 FPS average. This provides a substantial margin above 144Hz refresh rates while preserving higher visual fidelity than Medium (225 FPS) or Low (259 FPS). The Ultra preset at 1440p yields 155 FPS average, which is still sufficient for high-refresh-rate displays, but the 35 FPS gain from dropping to High settings represents a meaningful performance uplift with minimal visual impact in most scenes.

For 1080p users, the High preset at 294 FPS average is the optimal selection. While Low settings reach 363 FPS and Medium reaches 346 FPS, these higher frame rates exceed the refresh rate capabilities of virtually all consumer displays. The Ultra preset at 240 FPS average also remains viable, but High provides a 22.5% performance advantage over Ultra while offering near-identical visual quality in practice.

The data consistently shows that the Medium preset provides the best minimum frame rate stability across all resolutions, with the 4K Medium minimum of 104 FPS being particularly impressive. For competitive players prioritizing frame rate consistency over absolute visual quality, Medium at any resolution offers the tightest frame pacing, as evidenced by the measured min/max ranges.

How This Combo Ranks

The Ryzen 9 5900X and RTX 4080 SUPER combination achieves a rank of 308 out of 3712 tested configurations in Doom, placing it in the top 8.3% of all systems evaluated. This ranking reflects the strong synergy between the 12-core CPU and the high-end GPU, though the position indicates that there are still 307 combinations that deliver higher average frame rates in this specific title.

The GPU's percentile ranking of 86 among all graphics cards, with an average benchmark score of 54209, places it just slightly below the non-SUPER RTX 4080 (54247, -0.1% delta) and above the AMD Radeon Pro W5700X (54828, -1.1% delta). This suggests that the RTX 4080 SUPER is at the upper echelon of GPU performance, though its nearest rivals are all within a 2.8% performance delta, indicating a tightly clustered competitive field.

The CPU's percentile ranking of 87, with an average benchmark score of 41376, shows similar positioning. Its nearest rivals include the Intel Core Ultra 7 366H (41263, +0.3% delta) and the Intel Core i7-14650HX (41576, -0.5% delta), all within a narrow 0.9% performance band. This indicates that the Ryzen 9 5900X remains competitive with newer processor generations in synthetic benchmarks, even though its architecture dates from an earlier period.

The combination's 308th rank out of 3712 suggests that while this pairing is very strong, it is not at the absolute peak of performance for Doom specifically. This is likely because Doom's engine scales well with both CPU and GPU resources, and combinations with even faster processors or more powerful GPUs can achieve higher frame rates, particularly at 1080p where the CPU's role becomes more prominent.

Across all resolutions, the pattern is consistent: Low settings provide the highest frame rates, followed by Medium, High, and finally Ultra. The relative performance gaps between presets are remarkably uniform across resolutions, with Medium consistently offering roughly 45% more performance than Ultra, and High offering roughly 22-23% more. This consistency indicates that the game's graphics settings scale linearly with GPU load rather than introducing CPU-side bottlenecks at specific quality levels.

The Medium preset's min/max data reveals that frame time consistency improves at higher resolutions. At 4K, the spread is 36 FPS (104 to 140), at 1440p it's 68 FPS (191 to 259), and at 1080p it's 104 FPS (294 to 398). This inverse relationship between resolution and frame rate variance suggests that at lower resolutions, the CPU has more headroom to push frame rates higher when scenes are less demanding, creating wider fluctuations. At 4K, the GPU is consistently saturated, resulting in more uniform frame delivery.
