Doom

The AMD Ryzen 7 5800X and NVIDIA GeForce RTX 4080 pairing delivers exceptional performance in Doom, with the data showing a system that scales impressively from 1080p to 4K. The benchmark results reveal a combination where the GPU's raw power is the primary driver of frame rates, while the CPU's 8-core, 16-thread configuration ensures that even at lower resolutions, the system remains fluid and responsive.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 5800X is built on the Zen 3 architecture, codenamed Vermeer, and manufactured on a 7 nm process by TSMC. This 5000-series processor features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.70 GHz. The CPU's cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a substantial 32 MB of L3 cache, which is crucial for gaming workloads that require rapid access to frequently used data.

In Doom, the CPU's role is evident when examining the frame rate progression across resolutions. At 1080p with Low settings, the system achieves 361 FPS, while at 4K with the same settings, it drops to 141 FPS. This 220 FPS difference indicates that the GPU becomes increasingly bottlenecked at higher resolutions, but the CPU's 8-core design ensures that even at 1080p, where the GPU has more headroom, the processor can keep up with the game's demands. The 16 threads allow for efficient handling of the game's background tasks, AI, and physics calculations without introducing stutter or frame pacing issues.

The 5800X's benchmark scores reinforce its gaming capability. Its 3DMark single-thread score of 943 and multi-thread score of 7,578 show a balanced performance profile. The Cinebench R23 scores of 1,574.5 single-core and 15,476 multi-core suggest that the CPU has strong single-thread performance, which is often more critical for game engines like the one powering Doom. The PassMark single-thread score of 3,445 and multi-thread score of 27,732 further corroborate this, placing the CPU in the 81st percentile among all CPUs tested.

The CPU's memory support includes dual-channel DDR4 with a bandwidth of 51.2 GB/s, which pairs well with the GPU's 716.8 GB/s memory bandwidth. While the game's frame rates at 1080p (295 FPS on High) are exceptionally high, they do not appear to be limited by the CPU's memory subsystem, as the 5800X's 32 MB L3 cache likely absorbs much of the data traffic that would otherwise stress system memory.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear pattern of GPU-bound scaling as resolution increases. At High settings, the average FPS drops from 295 at 1080p to 191 at 1440p, and then to 104 at 4K. This represents a 35% reduction from 1080p to 1440p, and a further 46% reduction from 1440p to 4K. The frame rate at 4K is only about a third of the 1080p figure, which is consistent with a GPU that is being pushed to its limits by the increased pixel count.

Examining the Low settings data provides additional insight: 361 FPS at 1080p drops to 260 FPS at 1440p (a 28% reduction) and then to 141 FPS at 4K (a 46% reduction from 1440p). The relatively smaller drop from 1080p to 1440p at Low settings, compared to High settings, suggests that the GPU is less saturated at lower quality presets, allowing the CPU to more effectively feed frames. However, the 4K Low result of 141 FPS still indicates a significant GPU workload.

The Ultra preset shows the most pronounced scaling: 241 FPS at 1080p, 156 FPS at 1440p (a 35% reduction), and 85 FPS at 4K (a 46% reduction from 1440p). This consistent ~35% and ~46% pattern across all settings strongly implies that the RTX 4080's rendering capabilities, specifically its pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s, are the limiting factor at higher resolutions. The CPU's 16 threads and high boost clock of 4.70 GHz appear sufficient to avoid bottlenecking, as evidenced by the high 1080p frame rates that approach the refresh rate limits of most displays.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 7 5800X and NVIDIA GeForce RTX 4080 achieves a rank of 301 out of 3,712 tested combos in Doom. This places the pairing in the top 8.1% of all systems tested, which is a strong result given the game's age and the hardware's capabilities. The rank is likely influenced by the fact that Doom, released in 2016, may not fully utilize the CPU's 16 threads or the GPU's advanced Ada Lovelace features, yet the raw power of both components still pushes the combo to an elite tier.

The high rank is particularly notable when considering that the RTX 4080 is listed as end-of-life, with its successor, the GeForce 50 series, already released. Despite this, the combo outperforms the vast majority of tested systems, suggesting that the 5800X's Zen 3 architecture and the RTX 4080's 16 GB of GDDR6X memory provide a balanced platform for this game. The combo's rank of 301 is above the 86th percentile GPU ranking and the 81st percentile CPU ranking, indicating that the synergy between the two components is slightly better than their individual percentile standings would suggest.

The nearest rivals to the RTX 4080, such as the RTX 4080 SUPER with a 0.1% delta in average score, would likely perform nearly identically in Doom, meaning the combo's rank is tightly clustered with the top-tier GPU options. The fact that the 5800X's closest CPU rivals, like the Intel Core Ultra 5 135H, are within 0.5% in benchmark scores, suggests that CPU choice has minimal impact on this particular game's frame rates, further emphasizing the GPU's dominance in driving the combo's overall ranking.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4080 is a formidable GPU based on the Ada Lovelace architecture, manufactured on a 5 nm process at TSMC. The GPU features 9,728 shading units, 304 texture mapping units, and 112 raster output pipelines, along with 76 RT cores and 304 tensor cores. Its clock speeds are set at a base of 2205 MHz with a boost of 2505 MHz, and the memory operates at 1400 MHz with an effective speed of 22.4 Gbps.

The 16 GB of GDDR6X memory on a 256-bit bus provides a bandwidth of 716.8 GB/s, which is more than sufficient for Doom at any resolution. The game's texture-heavy environments and particle effects can benefit from this memory capacity, especially at 4K Ultra where the average FPS of 85 indicates the GPU is working hard. The GPU's FP32 performance of 48.74 TFLOPS and pixel rate of 280.6 GPixel/s are key contributors to the high frame rates observed, particularly at 1080p where the GPU can render frames at an average of 361 FPS on Low settings.

The RTX 4080's DirectX 12 Ultimate support and Vulkan 1.4 compatibility align well with Doom's engine, which was one of the early adopters of Vulkan API. The GPU's PassMark G3D score of 34,457 and 3DMark Steel Nomad DX12 score of 6,567 reflect its strong synthetic performance. In the context of Doom, the GPU's 86th percentile ranking among all GPUs and its average benchmark score of 54,247, which is nearly identical to the RTX 4080 SUPER's 54,209, indicate that the RTX 4080 is at the top of the performance hierarchy, with only a 0.1% difference separating it from its immediate successor.

The GPU's power requirements are substantial, with a TDP of 320 W and a suggested PSU of 700 W, but these figures do not directly impact in-game performance. The triple-slot cooler and 310 mm length suggest that adequate case space is needed, but the data shows that the GPU's thermal design does not impede its ability to deliver consistent frame rates across all tested settings and resolutions.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the system delivers outstanding performance across all presets. The Low settings produce an average of 361 FPS, while Medium settings yield 344 FPS with a minimum of 293 and a maximum of 396. The High preset averages 295 FPS, and the Ultra preset averages 241 FPS. The spread between Low and Ultra is 120 FPS, indicating that the Ultra preset imposes a significant rendering load but still maintains frame rates well above 200 FPS.

Moving to 2560x1440, the frame rates remain high but show a clear reduction. Low settings average 260 FPS, Medium averages 226 FPS with a minimum of 192 and a maximum of 260, High averages 191 FPS, and Ultra averages 156 FPS. The difference between Low and Ultra is 104 FPS, which is slightly less than at 1080p, suggesting that the GPU is becoming more of a limiting factor. The minimum FPS at Medium (192) is still above the 1440p High average, indicating that even the lower settings provide a smooth experience.

At 3840x2160, the performance drops are more pronounced. Low settings average 141 FPS, Medium averages 123 FPS with a minimum of 104 and a maximum of 141, High averages 104 FPS, and Ultra averages 85 FPS. The gap between Low and Ultra narrows to 56 FPS, which shows that at 4K, the GPU is heavily taxed and the settings have a relatively smaller impact on frame rates. Notably, the Medium preset's minimum FPS of 104 matches the High preset's average, suggesting that the Medium preset offers a better balance of visual quality and performance at 4K.

The data also shows that the Medium preset consistently has the most complete FPS range data, with min and max values recorded. At 1080p Medium, the range is 293 to 396 FPS, at 1440p Medium it is 192 to 260 FPS, and at 4K Medium it is 104 to 141 FPS. This suggests that the Medium preset is the most stable in terms of frame pacing, with the minimum and maximum values bracketing the average in a predictable manner.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the Medium preset emerges as the most balanced option across all three resolutions. At 1080p, Medium delivers 344 FPS with a minimum of 293 FPS, which is only 17 FPS lower than Low and a substantial 103 FPS higher than Ultra. The visual upgrade from Low to Medium is typically significant, and the frame rate sacrifice is minimal, making Medium the optimal choice for competitive play on high-refresh-rate monitors.

At 1440p, Medium provides 226 FPS with a minimum of 192 FPS, which is 34 FPS higher than High and 70 FPS higher than Ultra. The minimum FPS of 192 ensures that even in graphically intense scenes, the frame rate stays well above the 144 Hz threshold, making Medium the clear winner for 1440p gaming. The Ultra preset at 156 FPS is still playable, but the 70 FPS drop from Medium to Ultra is not justified by the marginal visual improvements in a fast-paced game like Doom.

At 4K, Medium averages 123 FPS with a minimum of 104 FPS, which is 19 FPS higher than High and 38 FPS higher than Ultra. The minimum FPS of 104 is just above the 100 FPS mark, ensuring a smooth experience on most displays. While Low settings at 141 FPS offer higher performance, the visual downgrade is often too severe for a modern game, and the 18 FPS difference between Low and Medium is a worthwhile trade-off for the improved image quality.

The High preset is the weakest recommendation, as it offers only 104 FPS at 4K, which is identical to the Medium preset's minimum FPS. At 1440p, High's 191 FPS is 35 FPS lower than Medium, and at 1080p, High's 295 FPS is 49 FPS lower. The Ultra preset should be reserved for players who prioritize maximum visual fidelity over frame rate, particularly at 1080p where 241 FPS is still exceptionally high, but at 4K, the 85 FPS average may not be suitable for competitive play. For the best balance of performance and quality, the data strongly supports the Medium preset at every resolution tested.
