Doom

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 2070 SUPER delivers a robust 1080p and 1440p experience in Doom, but the data reveals a clear shift in bottleneck behavior as resolution climbs. This combination ranks 1038th out of 1681 tested combos in this title, placing it in the upper-middle tier of the database. The measured frames per second across three resolutions and four quality presets tell a consistent story about where the system's strengths and limitations lie.

Resolution Scaling

The FPS progression from 1920x1080 to 3840x2160 is steep and predictable, indicating a system that transitions from CPU-bound at lower resolutions to heavily GPU-bound at 4K. At 1080p with High settings, the combo produces 158.9 FPS, which drops to 98.7 FPS at 1440p, a 38% reduction. Moving to 4K High yields 57.3 FPS, another 42% drop from 1440p. This scaling pattern is typical of a GPU that becomes the primary constraint as pixel count increases.

The Low preset at 1080p reaches 209.4 FPS, demonstrating that the CPU can push well beyond 200 frames when the GPU workload is minimized. At this resolution, the gap between Low and High is 50.5 FPS, showing that even at 1080p, the GPU still has headroom to influence performance. However, the fact that Low at 1080p exceeds 200 FPS while High at 4K falls below 60 FPS suggests the GPU is the limiting factor at higher resolutions, while the CPU's capability is only fully exposed at 1080p.

At 4K, the spread between presets narrows in absolute terms. The difference between Low at 71.7 FPS and High at 57.3 FPS is just 14.4 FPS, compared to a 50.5 FPS spread at 1080p. This compression indicates that at 4K, the GPU is saturated regardless of settings, and the rendering workload dominates all other factors. The Ultra preset at 4K falls to 45.7 FPS, which is below the 60 FPS threshold commonly desired for smooth gameplay.

GPU Role

The RTX 2070 SUPER is the dominant component in this pairing when resolution increases. Its 8 GB of GDDR6 memory on a 256-bit bus provides 448.0 GB/s of bandwidth, which is sufficient for Doom's textures at 1440p but becomes strained at 4K. The GPU's base clock of 1605 MHz and boost clock of 1770 MHz, combined with 2560 shading units, deliver a peak FP32 throughput of 9.062 TFLOPS. These specifications explain why the card can handle 1080p and 1440p with ease but falls below 60 FPS at 4K High.

The data shows the GPU's memory subsystem is likely a key factor at 4K. The bandwidth of 448.0 GB/s, while respectable for its era, is challenged by the increased texture and geometry data at 3840x2160. The measured 4K results—57.3 FPS at High, 63.9 FPS at Medium, and 71.7 FPS at Low—indicate that reducing quality settings helps, but the GPU's raw compute and memory bandwidth still cap performance below 72 FPS even at Low. This suggests the GPU is the hard limit at 4K, not the CPU or memory bandwidth of the system.

The RTX 2070 SUPER's Turing architecture includes 40 RT cores and 320 tensor cores, though Doom does not utilize ray tracing or DLSS in these measurements. The card's 64 ROPs and 160 TMUs provide a texture rate of 283.2 GTexel/s, which is adequate for the game's fast-paced environments but does not save it from the 4K compute demands. The GPU's percentile ranking of 65 against all GPUs places it mid-pack, and its nearest rivals include the RTX 4060 Mobile at 2.3% higher average score and the RX 5700 at 2.5% lower, showing it sits in a competitive but not dominant position.

Settings Recommendations

For 1080p gameplay, the Ultra preset at 128.7 FPS provides the best combination of visual quality and performance, staying well above the 60 FPS threshold and even exceeding 120 FPS for high-refresh-rate displays. The High preset at 158.9 FPS offers a meaningful 30.2 FPS boost over Ultra, but the visual fidelity difference may not justify the trade-off for most players. At 1080p, even the most demanding settings leave ample headroom, so the recommendation is to prioritize image quality.

At 1440p, the High preset at 98.7 FPS is the sweet spot. It delivers near-100 FPS performance while maintaining good visual fidelity. The Medium preset at 117.6 FPS offers a 19% performance increase over High but with reduced visual quality. Ultra at 80.2 FPS remains playable but dips closer to the 60 FPS boundary, making High the safer choice for consistent frame pacing. Low at 138 FPS is unnecessary at this resolution given the GPU's capability.

At 4K, the situation changes dramatically. The Medium preset at 63.9 FPS is the only setting that keeps the average above 60 FPS while providing reasonable visuals. High at 57.3 FPS falls just short of that threshold, and Ultra at 45.7 FPS is too demanding for smooth gameplay. Low at 71.7 FPS provides the highest frame rate but sacrifices too much visual quality. The data indicates that 4K Medium is the maximum viable configuration, and players seeking higher fidelity should consider reducing resolution to 1440p.

How This Combo Ranks

The combo's rank of 1038 out of 1681 tested combinations places it in the 62nd percentile of all systems in the database for Doom. This is a solid mid-tier position, reflecting the balance between the Ryzen 5 8400F's strong single-thread performance and the RTX 2070 SUPER's capable but not top-tier rendering power. The CPU's average benchmark score of 25064 places it in the 82nd percentile against all CPUs, while the GPU's average score of 22206 places it in the 65th percentile against all GPUs.

The CPU's nearest rivals show how close the 8400F is to other processors. The AMD Ryzen 7 2700X scores 25057, a 0% difference, meaning the two are effectively tied in average benchmarks. The Ryzen AI 5 PRO 340 is 0.1% higher, and the EPYC 9474F is 0.2% higher. The Ryzen 5 7500F is 0.3% lower. This tight grouping indicates the 8400F's performance is well-established within its class, and the measured Doom results align with this positioning.

The GPU's nearest rivals similarly show a narrow band. The RTX A400 is 0.5% higher, the GTX TITAN Z is 0.9% lower, and the RTX 4060 Mobile is 2.3% higher. The RX 5700 is 2.5% lower. These small deltas suggest that the RTX 2070 SUPER's performance in Doom is representative of its general benchmark standing, with no unusual game-specific advantages or disadvantages.

CPU Role

The AMD Ryzen 5 8400F, based on the Zen 4 Phoenix architecture built on a 4 nm process, provides 6 cores and 12 threads with a base clock of 4.20 GHz and boost clock of 4.70 GHz. Its 16 MB of shared L3 cache and dual-channel DDR5 memory support with 83.2 GB/s bandwidth are well-suited for a fast-paced FPS like Doom. The CPU's single-thread benchmark scores are particularly relevant: a Cinebench R23 single-core score of 2943 and a 3DMark single-thread score of 951 indicate strong per-core performance, which is crucial for game logic and frame pacing.

The data shows the CPU is not the limiting factor at 4K, as evidenced by the consistent FPS drops when increasing resolution. However, at 1080p, the CPU's capability is more visible. The jump from Low at 209.4 FPS to High at 158.9 FPS shows that the GPU still has influence even at lower resolution, but the CPU's ability to feed frames above 200 FPS demonstrates it is not holding back the system. The 3DMark 8-thread score of 5275 and max-thread score of 6165 show good scaling across cores, which helps maintain consistent performance in Doom's multi-threaded engine.

The CPU's 65 W TDP and unlocked multiplier suggest it can sustain boost clocks under load, though the measured FPS does not indicate thermal throttling as a factor. The 8400F's percentile rank of 82 against all CPUs places it above average, and its nearest rival, the Ryzen 7 2700X, being exactly matched in average score (25057 vs 25064) confirms the 8400F holds its own against older high-core-count parts. In Doom specifically, the CPU's strong single-thread performance ensures that even at 1080p with Low settings, the system can exceed 200 FPS, which is the hallmark of a well-balanced pairing for this title.
