# CPU Role

The AMD Ryzen 7 5800X3D is an 8-core, 16-thread processor based on the Zen 3 architecture (Vermeer codename), manufactured on TSMC's 7 nm process. It operates with a base clock of 3.40 GHz and a boost clock of 4.50 GHz. The 96 MB of shared L3 cache is a defining feature of this chip, which helps in gaming workloads that benefit from large, fast cache pools.

In Doom, the CPU's role is to feed the GPU with draw calls and game logic data. The 5800X3D's multi-threaded performance is solid but not exceptional relative to its peers. In Cinebench R23 multi-core, it scores 14,317 points, while its single-core score is 1,452. The Geekbench scores show 11,765 multi-core and 2,017 single-core. These numbers place the CPU in the 80th percentile of all processors, with an average benchmark score of 27,896.

The nearest rivals illustrate the competitive landscape. The AMD Ryzen 7 6800U scores 27,887 (0% delta), the Intel Core i9-10900K scores 27,872 (0.1% delta), the AMD Ryzen AI 5 PRO 340 scores 27,932 (-0.1% delta), and the Intel Core i5-12600KF scores 27,799 (0.3% delta). The differences are negligible, meaning the 5800X3D is effectively on par with these alternatives in general compute. However, the 3D V-Cache design specifically targets gaming, and the measured FPS data reflects that the CPU is not a bottleneck in Doom at any resolution tested.

The 3DMark results show a single-thread score of 884, a 2-thread score of 1,746, a 4-thread score of 3,392, an 8-thread score of 5,906, and a max-thread score of 7,285. The scaling from 8 to 16 threads is minimal (5,906 to 7,285), suggesting that Doom does not heavily utilize all 16 threads, but the 8-core performance is strong enough to sustain high frame rates.

At 1080p with Low settings, the combo achieves 312 FPS, which is the highest recorded in this dataset. This indicates that the CPU can push frames well beyond typical display refresh rates. The fact that the CPU's nearest rivals have nearly identical average benchmark scores suggests that swapping to any of those chips would not materially change the CPU-bound performance in this game. The 5800X3D's advantage lies in its cache hierarchy, which the benchmark data cannot directly quantify but the FPS numbers imply effective utilization.

The CPU supports DDR4 memory with dual-channel bandwidth of 51.2 GB/s, and ECC memory is supported. It uses the AMD Socket AM4 platform with PCIe Gen 4 (20 lanes from the CPU). The TDP is 105 W, and it was released in April 2022 with a launch MSRP of $449. The production status is end-of-life, but its performance in Doom remains competitive.

# GPU Role

The NVIDIA GeForce RTX 3080 Ti is built on the Ampere architecture (GA102 chip) using Samsung's 8 nm process. It features 10,240 shading units, 320 TMUs, and 112 ROPs. The boost clock is 1665 MHz, with a base clock of 1365 MHz. Memory is 12 GB of GDDR6X on a 384-bit bus, delivering 912.4 GB/s of bandwidth. The GPU's FP32 compute is 34.10 TFLOPS, and it has 80 RT cores and 320 tensor cores.

In Doom, the GPU is the primary driver of frame rates at higher resolutions and settings. The data shows a clear hierarchy: at 4K Ultra, the average FPS is 66, while at 4K Low it rises to 109. The GPU's 83rd percentile ranking (average score 41,187) places it above the AMD Radeon Pro 5300 (40,870, 0.8% delta) but below the NVIDIA Tesla M40 24 GB (41,707, -1.2% delta) and the NVIDIA Tesla M40 (41,897, -1.7% delta). The NVIDIA GeForce RTX 5070 scores 40,377, a 2% delta.

The GPU's memory bandwidth of 912.4 GB/s is critical for Doom's texture-heavy environments. At 4K Medium, the average FPS is 95 with a minimum of 81 and maximum of 110, showing that the memory subsystem can handle the data throughput without severe dips. The pixel rate is 186.5 GPixel/s and texture rate is 532.8 GTexel/s, which are high enough to sustain the observed frame rates.

The 3080 Ti was released in May 2021 with a launch MSRP of 1,199 USD. It is a dual-slot card requiring a 750 W PSU, with a 1x 12-pin power connector. The TDP is 350 W. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, which are relevant for modern game APIs.

The benchmark results for the GPU show a Passmark G3D score of 26,896, which is a strong indicator of general 3D performance. The Geekbench OpenCL score is 170,037, and Vulkan is 192,697. These numbers align with the GPU's percentile ranking and support the observed FPS in Doom.

At 1080p, the GPU is less stressed, and the CPU takes a larger role. However, even at 1080p Low (312 FPS), the GPU is not limiting, as the frame rate is exceptionally high. The scaling from 1080p to 4K at High settings (230 to 81 FPS) shows a 65% drop, which is consistent with a GPU-bound scenario at higher resolutions.

# Measured FPS Breakdown

The measured FPS data covers four settings (Low, Medium, High, Ultra) at three resolutions (1080p, 1440p, 4K). Each row represents the average FPS, with some rows including minimum and maximum values.

At 1920x1080, the Low setting yields 312 FPS average. Medium produces 272 FPS with a minimum of 231 and maximum of 313. High delivers 230 FPS. Ultra drops to 188 FPS. The difference between Low and Ultra is 124 FPS, a 40% reduction, showing that the GPU scaling is significant at this resolution but still maintains playable frame rates.

At 2560x1440, the Low setting averages 202 FPS. Medium averages 176 FPS with a minimum of 150 and maximum of 202. High sits at 149 FPS. Ultra drops to 122 FPS. The gap between Low and Ultra is 80 FPS, a 40% reduction, mirroring the 1080p scaling pattern.

At 3840x2160, the Low setting averages 109 FPS. Medium averages 95 FPS with a minimum of 81 and maximum of 110. High averages 81 FPS. Ultra drops to 66 FPS. The reduction from Low to Ultra is 43 FPS, a 39% drop.

The minimum FPS data for Medium settings shows the following: at 1080p, the min is 231 FPS; at 1440p, the min is 150 FPS; at 4K, the min is 81 FPS. These minimums are all above 60 FPS, indicating that the combo maintains smooth gameplay even in demanding scenes.

The FPS scaling across resolutions is consistent. From 1080p to 1440p at Medium, the FPS drops from 272 to 176, a 35% reduction. From 1440p to 4K, it drops from 176 to 95, a 46% reduction. The cumulative drop from 1080p to 4K is 65%. At High settings, the drop from 1080p (230) to 1440p (149) is 35%, and from 1440p to 4K (81) is 46%. At Ultra, the drops are 35% (188 to 122) and 46% (122 to 66), respectively.

These numbers indicate that the GPU becomes the limiting factor as resolution increases. The consistent percentage drops across settings suggest that the CPU is not a bottleneck at any resolution, as the scaling is purely resolution-driven.

# How This Combo Ranks

The combo ranks 963rd out of 3,712 tested CPU-GPU pairings in Doom. This places it in the top 26% of all combinations tested. The rank is a relative measure of overall performance, comparing this specific pairing against all others in the database for this game.

Given the CPU's 80th percentile ranking and the GPU's 83rd percentile ranking, the combo's position at the 74th percentile (963/3712) is slightly lower than either component's individual percentile. This suggests that the pairing, while strong, does not perfectly synergize to reach the top quartile of combos. The CPU and GPU are both high performers, but the combo rank reflects that some other pairings achieve better overall results in Doom.

The nearest rival CPUs (Ryzen 7 6800U, Core i9-10900K, Ryzen AI 5 PRO 340, Core i5-12600KF) have nearly identical average scores, so swapping the CPU would likely not change the rank significantly. Similarly, the GPU's nearest rivals (Radeon Pro 5300, Tesla M40 24 GB, Tesla M40, RTX 5070) have scores within 2% of the 3080 Ti, meaning the rank is influenced more by the combination's balance than by any single component's dominance.

The rank of 963 out of 3,712 indicates that this is a high-performing combo, but it is not at the very top. For a game like Doom, which is well-optimized and can leverage high-end hardware, the rank is competitive. The data suggests that the combo is well-suited for high-refresh-rate gaming at 1440p and solid 4K performance, which aligns with the FPS measurements.

# Settings Recommendations

The measured FPS data provides clear guidance on optimal settings for different priorities. For the best balance of visual quality and performance, Medium settings are recommended. At 1080p Medium, the combo achieves 272 FPS average with a minimum of 231 FPS, ensuring smooth gameplay even in intense scenes. At 1440p Medium, the average is 176 FPS with a minimum of 150 FPS, comfortably above the 144 Hz refresh rate for most monitors. At 4K Medium, the average is 95 FPS with a minimum of 81 FPS, which is playable but may not fully utilize high-refresh-rate 4K displays.

High settings are a viable alternative for those prioritizing visual fidelity. At 1080p, High delivers 230 FPS, which is still well above 144 Hz. At 1440p, High averages 149 FPS, which is slightly below 165 Hz but still smooth. At 4K, High drops to 81 FPS, which is borderline for 60 Hz displays but acceptable for slower-paced gameplay.

Ultra settings are only recommended for users with 1080p displays, where the 188 FPS average remains high. At 1440p Ultra, the 122 FPS average is still respectable, but at 4K Ultra, the 66 FPS average approaches the lower limits of smooth gameplay. Low settings are not recommended for visual quality reasons, but they demonstrate the combo's headroom: 312 FPS at 1080p and 109 FPS at 4K.

The data shows that Medium settings offer the best performance-per-visual-quality trade-off across all resolutions. The minimum FPS values for Medium are consistently higher than the average FPS for Ultra at the same resolution, indicating that Medium provides a more stable experience. For example, at 1440p, the Medium minimum of 150 FPS exceeds the Ultra average of 122 FPS. At 4K, the Medium minimum of 81 FPS is higher than the Ultra average of 66 FPS.

# Resolution Scaling

The FPS scaling from 1080p to 4K reveals the limiting component. At Medium settings, the FPS drops from 272 at 1080p to 176 at 1440p, a 35% reduction. From 1440p to 4K, the FPS drops from 176 to 95, a 46% reduction. The overall drop from 1080p to 4K is 65%.

This scaling pattern is consistent with a GPU-bound scenario. The pixel count increases by 2.25x from 1080p to 1440p, and by 2.25x from 1440p to 4K (a total of 5.06x from 1080p to 4K). The FPS drops are not proportional to the pixel count increase, which is expected because frame rate scaling is not linear with resolution due to other bottlenecks (e.g., memory bandwidth, shading throughput).

At High settings, the same pattern holds: 230 FPS at 1080p drops to 149 FPS at 1440p (35% drop) and further to 81 FPS at 4K (46% drop). At Ultra settings, the drops are 35% (188 to 122) and 46% (122 to 66). The identical percentage drops across settings indicate that the limiting factor is the GPU's rendering capability, not the CPU.

The CPU's role in resolution scaling is minimal. If the CPU were the bottleneck, the FPS would remain constant or drop less as resolution increases, because the CPU workload does not change significantly with resolution. The data shows a consistent drop, confirming that the RTX 3080 Ti is the primary limiter at higher resolutions.

The minimum FPS values for Medium settings provide additional insight: at 1080p, the minimum is 231 FPS; at 1440p, it is 150 FPS; at 4K, it is 81 FPS. These minimums follow the same scaling pattern as the averages, reinforcing the GPU-bound nature. The GPU's memory bandwidth of 912.4 GB/s is sufficient to avoid stutters, as the minimum FPS never drops below 81 FPS even at 4K.

For users targeting 4K, the data suggests that Medium settings (95 FPS average) or High settings (81 FPS average) are the best options, as Ultra drops to 66 FPS. For 1440p, all settings are viable, with Ultra at 122 FPS being the highest visual quality option above 60 FPS. At 1080p, even Ultra maintains 188 FPS, making this resolution the most forgiving for the combo's performance.
