Doom

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 4070 combination delivers a remarkably consistent high-refresh-rate experience in Doom across all tested resolutions, with the data showing that even the most demanding preset at 4K clears the 60 FPS playability threshold with measurable headroom. This pairing of a Zen 4 six-core processor with an Ada Lovelace GPU produces average frame rates that scale predictably with resolution, suggesting a balanced system where the GPU becomes the primary scaling factor as pixel count rises, while the CPU maintains sufficient throughput to avoid bottlenecking even at lower resolutions where frame rates exceed 300 FPS.

Best Settings per Resolution

At 3840x2160, the most demanding preset that maintains at least 60 FPS is Ultra, with an average frame rate of 64.5 FPS. This is the tightest margin in the entire dataset, sitting only 4.5 frames above the playability threshold. The data shows that High settings at this resolution produce 81.1 FPS, Medium reaches 94.7 FPS, and Low achieves 111 FPS, so there is meaningful performance headroom if the Ultra preset proves too demanding in specific scenes.

For 2560x1440, the Ultra preset is again the highest playable option, delivering an average of 122.7 FPS. This is more than double the 60 FPS threshold, indicating that the system is far from stressed at this resolution. The scaling from High to Ultra at 1440p shows a drop from 146.5 FPS to 122.7 FPS, a 16.2% reduction, which is proportionally similar to the 4K scaling pattern between those same presets.

At 1920x1080, the Ultra preset runs at an average of 186.5 FPS, making it the clear choice for maximum visual fidelity without any concern for playability. The data indicates that even the most demanding preset at 1080p provides nearly three times the minimum acceptable frame rate. Lower presets at this resolution reach exceptionally high values, with Low hitting 312.8 FPS, Medium at 271.9 FPS, and High at 230.9 FPS, which suggests the system is heavily GPU-limited at these settings rather than constrained by the CPU.

CPU and GPU Roles

The performance scaling across resolutions reveals that the GPU is the dominant factor in Doom for this combination. Moving from 1920x1080 to 2560x1440 at Ultra settings reduces the average frame rate from 186.5 FPS to 122.7 FPS, a 34.2% decrease. Further scaling to 3840x2160 at Ultra drops the average to 64.5 FPS, another 47.4% reduction from the 1440p result. This consistent degradation with increasing pixel count strongly indicates GPU-bound behavior throughout the tested range.

The CPU's role becomes more apparent at lower resolutions and lower presets. At 1080p Low, the system produces 312.8 FPS, which is 67.7% higher than the 186.5 FPS at 1080p Ultra. This substantial gap between presets at the same resolution suggests that the Ryzen 5 8400F can feed the GPU with enough frames to reach very high rates, but the rendering load still scales with settings. The 8400F's benchmark scores, including a Cinebench R23 multi-core result of 20851 and a single-core score of 2943, indicate strong per-thread performance that supports high frame rates. Its 3DMark single-thread score of 951 and 2-thread score of 1874 further confirm that the CPU is not likely to be the limiting factor in this game.

The pattern across resolutions shows that the GPU's memory bandwidth of 504.2 GB/s and 12 GB of GDDR6X memory handle the increasing resolution demands effectively. The transition from 1440p to 4K at Medium settings shows a drop from 175.8 FPS to 94.7 FPS, a 46.1% reduction, which aligns closely with the pixel count increase of 2.25 times. This near-linear scaling with resolution is characteristic of a GPU-bound scenario, where the CPU's role remains relatively constant while the GPU's workload expands significantly.

Similar Performance Alternatives

The Ryzen 5 8400F's nearest rivals in benchmark performance include the AMD Ryzen 5 7500F, which scores nearly identically at 24964 average benchmark points versus 25005 for the 8400F, a mere 0.2% difference. The Intel Core i7-11850H and Intel Core i7-13620H also sit close, with scores of 24935 and 24911 respectively, representing 0.3% and 0.4% deltas. The AMD EPYC 9474F trails slightly at 25103 points, which is 0.4% lower than the 8400F's score. For Doom specifically, any of these CPUs would likely produce nearly identical frame rates in this GPU-bound scenario, as the differences are within measurement noise.

On the GPU side, the RTX 4070's nearest rivals present a more varied picture. The NVIDIA Tesla P4 scores 37628 average benchmark points versus 37648 for the RTX 4070, a 0.1% difference that would translate to negligible frame rate variations in Doom. The AMD Radeon RX Vega 56 at 37507 points is 0.4% behind, while the NVIDIA GeForce RTX 4080 Mobile at 38135 points is 1.3% ahead. The AMD Radeon PRO W6400 at 37157 points is 1.3% behind the RTX 4070. In practice, these rivals would produce nearly identical performance in Doom, with the RTX 4080 Mobile potentially delivering slightly higher frame rates at 4K Ultra where the GPU is most stressed.

The Verdict

This PC can run Doom at playable frame rates across every resolution and preset combination tested. The verdict data confirms that all four settings presets at each resolution—Low, Medium, High, and Ultra—maintain average frame rates at or above the 60 FPS playability threshold. At 3840x2160, the Ultra preset achieves 64.5 FPS, which clears the threshold by a modest 7.5% margin. The 2560x1440 resolution offers substantial headroom with Ultra at 122.7 FPS, more than double the minimum requirement. At 1920x1080, the system delivers 186.5 FPS on Ultra, providing an extremely smooth experience that would satisfy even demanding competitive players.

The most notable consideration is the 4K Ultra result, where the 64.5 FPS average leaves little room for frame rate dips. Players seeking a guaranteed consistent experience at 4K might prefer High settings at 81.1 FPS, which provides a 35% buffer above the threshold. However, the data shows that the system is unequivocally capable of running the game at maximum settings at all resolutions without dropping below the playability standard.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are 312.8 FPS on Low, 271.9 FPS on Medium, 230.9 FPS on High, and 186.5 FPS on Ultra. The progression from Low to Ultra represents a 40.4% reduction in average frame rate, reflecting the increased rendering workload from higher quality settings. The gap between Medium and High is 41 FPS, while the gap between High and Ultra is 44.4 FPS, showing relatively consistent scaling across the preset ladder.

At 2560x1440, the frame rates are 202.4 FPS on Low, 175.8 FPS on Medium, 146.5 FPS on High, and 122.7 FPS on Ultra. The reduction from Low to Ultra is 39.4%, slightly less than at 1080p, which suggests that the GPU is becoming more of a limiting factor as resolution increases. The difference between High and Ultra at 1440p is 23.8 FPS, which is proportionally smaller than at 1080p.

At 3840x2160, the results are 111 FPS on Low, 94.7 FPS on Medium, 81.1 FPS on High, and 64.5 FPS on Ultra. The scaling from Low to Ultra shows a 41.9% reduction, and the gap between High and Ultra is 16.6 FPS. The 4K results demonstrate the steepest performance curve, with the Ultra preset barely maintaining playability at 64.5 FPS. The data does not include minimum or maximum frame rate values, so the analysis relies solely on average performance, which typically indicates higher frame rates than the 1% lows would show.

How This Combo Ranks

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 4070 combination ranks 988 out of 3712 tested combos for Doom, placing it in the top 26.6% of all systems evaluated. This ranking reflects a strong overall performance level that is consistent with the high frame rates observed across all resolutions and presets. The percentile ranking of the CPU at 77% and GPU at 81% suggests that both components perform above the median in their respective categories, and their combination in this game produces results that align with those individual standings.

The rank of 988 out of 3712 indicates that while this system is well above average, it is not at the top tier of performance. The data shows that higher-ranked combinations would likely include more powerful GPUs with greater memory bandwidth and shading units, which would provide additional headroom at 4K Ultra where this system's 64.5 FPS is its weakest result. However, the combination's ranking also reflects that it outperforms approximately 73% of all tested systems in Doom, demonstrating that it is a capable configuration for this title.
