Doom

Settings Recommendations

The measured data for Doom with the AMD Ryzen 7 5700X3D and NVIDIA GeForce RTX 3080 shows a clear hierarchy across the four available presets: Low, Medium, High, and Ultra. At every resolution, the Low preset delivers the highest average frame rate, but the experience is best balanced at the High preset. The High preset provides a substantial performance uplift over Ultra while maintaining visual fidelity, making it the recommended choice for most users.

At 1920x1080, the High preset achieves an average of 222.9 FPS, which is 42.1 FPS higher than Ultra’s 180.8 FPS. The Medium preset sits between them at 260.9 FPS, but High offers a better compromise between image quality and speed. The data indicates that Ultra’s additional graphical effects cost roughly 19% of the frame rate compared to High at this resolution, a penalty that may not justify the visual gains in a fast-paced FPS.

Moving to 2560x1440, the High preset delivers 141.3 FPS, comfortably above the 119.3 FPS seen at Ultra. The Medium preset reaches 171.9 FPS, but High remains the sweet spot. At 3840x2160, High drops to 77.5 FPS, still playable, while Ultra falls to 62.4 FPS, which may feel less fluid. Low at 4K hits 105.8 FPS, but the visual compromise is severe.

For those prioritizing maximum refresh rate on a 144Hz or 240Hz monitor, the Medium preset is a viable alternative to High, offering 260.9 FPS at 1080p and 171.9 FPS at 1440p. However, the measured data suggests that High is the optimal preset for the majority of hardware configurations, as it maintains high frame rates without sacrificing the game’s core visual identity.

GPU Role

The NVIDIA GeForce RTX 3080 is the primary driver of frame rates in Doom, and its specifications explain the performance scaling observed. The GPU features 10 GB of GDDR6X memory on a 320-bit bus, delivering a bandwidth of 760.3 GB/s. This memory configuration is sufficient for Doom’s textures and effects at all tested settings, as evidenced by the consistent frame rates across presets.

The RTX 3080’s clock speeds are notable: a base clock of 1440 MHz and a boost clock of 1710 MHz. The GPU’s 8704 shading units and 272 texture mapping units allow it to process the game’s geometry and lighting efficiently. The pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s are high enough to handle Doom’s demanding scenes without bottlenecking the CPU.

The GPU’s 68 ray tracing cores and 272 tensor cores are present, though Doom does not heavily utilize these features in the measured presets. The FP32 performance of 29.77 TFLOPS indicates raw computational power, which translates directly to the high frame rates seen at 1080p and 1440p. At 4K, the GPU becomes the limiting factor, as the frame rate drops from 222.9 FPS at 1080p High to 77.5 FPS at 4K High, a reduction of 65%.

The RTX 3080’s percentile ranking of 80 versus all GPUs places it in the upper tier, and its nearest rivals include the AMD Radeon RX 7900 GRE, which scores slightly higher, and the NVIDIA GeForce RTX 5070 Ti Mobile, which scores slightly lower. These comparisons underscore that the RTX 3080 is a capable card for Doom, though not the absolute fastest.

Resolution Scaling

The measured FPS data reveals how the RTX 3080 and Ryzen 7 5700X3D combo scales across resolutions. At 1920x1080 with High settings, the average FPS is 222.9. Moving to 2560x1440, this drops to 141.3 FPS, a reduction of 36.6%. At 3840x2160, the frame rate falls to 77.5 FPS, a further reduction of 45.1% from 1440p.

This scaling pattern indicates that the GPU is the limiting component at higher resolutions. The CPU, with its 8 cores and 16 threads, is capable of pushing frame rates well above 300 FPS at 1080p Low (303.5 FPS), but the GPU’s pixel throughput cannot keep pace as resolution increases. The 4K High result of 77.5 FPS is still playable, but it represents a significant drop from the 1080p experience.

The Low preset shows a similar trend: 303.5 FPS at 1080p, 196.2 FPS at 1440p, and 105.8 FPS at 4K. The percentage drops are consistent, suggesting that the GPU’s workload scales linearly with pixel count. The Ultra preset, while visually demanding, follows the same pattern, with 180.8 FPS at 1080p, 119.3 FPS at 1440p, and 62.4 FPS at 4K.

For users with a 1440p monitor, the High preset’s 141.3 FPS is ideal. For 4K displays, the Low preset’s 105.8 FPS is the only option above 100 FPS, indicating that the GPU is stretched thin at this resolution. The data clearly shows that 1080p is where this combo excels, with all presets exceeding 180 FPS.

Measured FPS Breakdown

At 1920x1080, the benchmark results show a wide range of performance. Low settings deliver an average of 303.5 FPS, the highest measured value in the entire dataset. Medium follows at 260.9 FPS, High at 222.9 FPS, and Ultra at 180.8 FPS. The spread between Low and Ultra is 122.7 FPS, highlighting the significant impact of graphical settings on frame rate.

At 2560x1440, the frame rates decrease but remain high. Low averages 196.2 FPS, Medium 171.9 FPS, High 141.3 FPS, and Ultra 119.3 FPS. The difference between Low and Ultra is 76.9 FPS, a narrower margin than at 1080p, indicating that the GPU is becoming more of a bottleneck.

At 3840x2160, the performance drops considerably. Low averages 105.8 FPS, Medium 92 FPS, High 77.5 FPS, and Ultra 62.4 FPS. The Ultra preset barely maintains 60 FPS, while Low just crosses the 100 FPS threshold. The total range across settings at 4K is 43.4 FPS, the smallest of any resolution, confirming that the GPU is saturated.

The data shows no min or max FPS values, only averages, so the frame time consistency cannot be assessed. However, the average values are consistently high across all presets and resolutions, indicating a stable experience.

How This Combo Ranks

The AMD Ryzen 7 5700X3D and NVIDIA GeForce RTX 3080 combination ranks 515th out of 1681 tested combos in Doom, placing it in the top 31% of all configurations. This ranking reflects a strong but not elite performance, consistent with the hardware’s individual percentiles: the CPU ranks in the 82nd percentile versus all CPUs, while the GPU ranks in the 80th percentile versus all GPUs.

The combo’s rank is influenced by the GPU’s 10 GB memory capacity, which may limit performance in other games but is sufficient for Doom. The CPU’s 96 MB of shared L3 cache is a standout feature, providing a significant advantage in gaming workloads, as evidenced by its benchmark scores. The CPU’s average benchmark score of 24673 is nearly identical to its nearest rival, the Intel Core i7-1360P, which scores 24627, a delta of 0.2%. The AMD Ryzen 5 7600X3D scores 24605, a delta of 0.3%, and the Intel Core i5-11600 scores 24559, a delta of 0.5%.

The GPU’s average benchmark score of 35787 is slightly below the AMD Radeon Pro Duo’s 35860 (delta -0.2%) and above the AMD Radeon 880M’s 35646 (delta 0.4%). The NVIDIA GeForce RTX 5070 Ti Mobile scores 35435, a delta of 1%. These comparisons show that the RTX 3080 is competitive with its peers, but the combo’s 515th rank suggests that other configurations offer higher frame rates in Doom.

CPU Role

The AMD Ryzen 7 5700X3D plays a supporting role in Doom, providing enough processing power to avoid bottlenecking the RTX 3080. The CPU has 8 cores and 16 threads, with a base clock of 3.00 GHz and a boost clock of 4.10 GHz. Its architecture is Zen 3, codenamed Vermeer, built on a 7 nm process by TSMC.

The CPU’s L3 cache is 96 MB shared, a critical feature for gaming. This large cache helps reduce memory latency, which is beneficial in Doom’s level-based design. The CPU’s benchmark scores reflect its strength: Cinebench R23 multicore scores 22366, and single-core scores 3157. These scores indicate that the CPU can handle the game’s physics and AI calculations without issue.

The CPU’s memory support includes DDR4 with a dual-channel bus, providing a memory bandwidth of 51.2 GB/s. This is sufficient for Doom, as the GPU’s 760.3 GB/s bandwidth is the primary data path. The CPU’s PCIe Gen 4 interface with 20 lanes ensures fast communication with the GPU, though Doom is not particularly demanding on this front.

At 1080p Low, the CPU can push frame rates to 303.5 FPS, demonstrating that it is not a limiting factor at lower resolutions. Even at 4K Ultra, the CPU’s role is less critical, as the GPU is clearly the bottleneck. The data indicates that the Ryzen 7 5700X3D is a well-matched companion for the RTX 3080, offering no measurable performance penalty in Doom.
