Doom

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 4070 Ti delivers a remarkably consistent experience in Doom, with frame rates that scale predictably across resolutions and settings. The data reveals a system that is overwhelmingly GPU-bound at higher resolutions, but shows interesting CPU headroom at 1080p. This combination ranks 214th out of 1681 tested combos, placing it in the top 13% of all configurations, which is a strong showing for a mid-range CPU paired with a high-end GPU. The following analysis breaks down exactly how this hardware handles id Software's 2016 shooter.

Resolution Scaling

The frame rate drop from 1080p to 4K is dramatic and tells a clear story about where the bottleneck lies. At 1080p with Ultra settings, the combo produces 221.5 FPS. Moving to 1440p drops that to 145.2 FPS, a reduction of about 34%. Stepping up to 4K further reduces performance to 78.3 FPS, which is roughly 46% lower than the 1440p result and only 35% of the 1080p figure. This steep, non-linear decline is the classic signature of a GPU-limited scenario.

The scaling pattern is consistent across all settings presets. With Low settings, the system goes from 369 FPS at 1080p to 236.4 FPS at 1440p, and finally to 129.1 FPS at 4K. The proportional drops are similar, though the absolute numbers are higher. This uniformity suggests that the RTX 4070 Ti's rendering pipeline is the limiting factor, not the CPU. If the processor were the constraint, we would expect to see a much smaller gap between 1080p and 1440p, as the CPU load per frame typically decreases at higher resolutions.

The data implies that at 1080p, the system has significant headroom. The jump from 221.5 FPS at Ultra to 271.4 FPS at High, and then to 319.6 FPS at Medium, shows that there is plenty of performance left on the table. The CPU is clearly capable of feeding the GPU with enough data to maintain these high frame rates, but the GPU's workload is what ultimately caps the output. At 4K, the GPU is heavily taxed, and the CPU's role becomes less relevant, as the frame rate is almost entirely determined by the graphics card's raw throughput.

Settings Recommendations

For players targeting the highest refresh rates, the choice of settings is critical. The data shows that dropping from Ultra to High at 1080p yields a significant boost of 49.9 FPS, from 221.5 to 271.4. This is a 22.5% performance gain for what is often a visually subtle reduction in quality. At 1440p, the same settings change moves the frame rate from 145.2 to 173.3 FPS, a 19.3% improvement. This makes the High preset the sweet spot for high-refresh-rate gaming, as it pushes the system closer to the 240Hz territory that many competitive players seek.

The Medium preset offers even more headroom. At 1080p, it delivers 319.6 FPS, which is 98.1 FPS higher than Ultra. This is a 44% improvement and will easily saturate any 240Hz or even 360Hz display. At 1440p, Medium produces 205.9 FPS, which is still exceptionally smooth and only 60.6 FPS below the Low preset's 236.4 FPS. The difference between Low and Medium is relatively small in percentage terms, with Medium being only 11.6% slower at 1080p and 12.9% slower at 1440p. Therefore, the Medium preset appears to be the best balance for 1440p, providing a massive frame rate boost over High while retaining most of the visual fidelity.

At 4K, the situation is different. The Ultra preset delivers 78.3 FPS, which is playable but not ideal for fast-paced action. Dropping to High brings the average up to 93.3 FPS, which is a solid 60Hz-plus experience. Medium further improves this to 112.1 FPS, and Low reaches 129.1 FPS. For 4K gaming, the High preset is recommended as it offers the best balance between visual quality and playable performance, keeping the frame rate above 90 FPS. The Medium preset is also a strong option for those who prioritize frame rate over fidelity, pushing the average above 110 FPS.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, with a base clock of 4.20 GHz and a boost clock of 4.70 GHz. In Doom, this CPU appears to be more than sufficient to keep up with the RTX 4070 Ti, even at high frame rates. The benchmark results for this CPU show a strong single-threaded performance, with a 3DMark single-thread score of 951 and a Cinebench R23 single-core score of 2943. This is crucial for a game like Doom, which is known for its efficient multi-threading but still relies heavily on strong single-core performance for the main game loop.

The CPU's multi-threaded capabilities are also robust, as evidenced by a Cinebench R23 multi-core score of 20851. This allows the processor to handle the various background tasks and physics calculations that Doom runs in parallel. The 16 MB of shared L3 cache is ample for the game's data footprint, ensuring that frequently accessed assets are kept close to the cores. The data suggests that the CPU is not the limiting factor at any resolution tested. Even at 1080p with Low settings, where the system produces 369 FPS, the CPU is able to supply the GPU with enough data to reach that high frame rate.

The fact that the frame rates scale so consistently with resolution indicates that the CPU's workload is relatively constant, while the GPU's workload increases with pixel count. This is the expected behavior for a well-balanced system. The Ryzen 5 8400F's performance is comparable to the AMD Ryzen 7 2700X, with a delta of 0% in average benchmark score, and it is 0.3% ahead of the Ryzen 5 7500F. This places it in a solid position for gaming, ensuring that it will not be a bottleneck in most scenarios.

How This Combo Ranks

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 4070 Ti combination ranks 214th out of 1681 tested combos in Doom. This puts it in the 87th percentile of all configurations, which is an excellent result. The high ranking is largely due to the RTX 4070 Ti's raw power, as the GPU is the primary driver of frame rates in this game. The GPU itself ranks in the 85th percentile of all graphics cards, with an average benchmark score of 44900. This places it in the same performance tier as the NVIDIA GeForce RTX 5090 Mobile, which has a delta of -0.6%, and the Intel Arc A730M, which is 1.5% slower.

The CPU's contribution to this ranking is also positive. The Ryzen 5 8400F sits in the 82nd percentile of all CPUs, with an average benchmark score of 25064. This is comparable to the AMD Ryzen 7 2700X, which has a delta of 0%, and the AMD Ryzen AI 5 PRO 340, which is only 0.1% faster. The combination of a high-percentile CPU and a high-percentile GPU results in a system that is well above average for this game. The ranking suggests that this combo is capable of delivering a premium gaming experience, with frame rates that will satisfy even the most demanding players. It is important to note that this ranking is specific to Doom, and the performance in other games may vary.

At 1440p, the frame rates remain very high, with the Ultra preset still achieving over 145 FPS. The 4K results are more modest, but the High preset's 93.3 FPS is still comfortably above the 60 FPS threshold for smooth gameplay.

GPU Role

The NVIDIA GeForce RTX 4070 Ti is the dominant component in this pairing for Doom. Its specifications are impressive, featuring 7680 shading units, 240 texture mapping units, and 80 render output units. The GPU's high texture rate of 626.4 GTexel/s and pixel rate of 208.8 GPixel/s are directly relevant to Doom's fast-paced, texture-heavy environments. The 12 GB of GDDR6X memory on a 192-bit bus provides a memory bandwidth of 504.2 GB/s, which is ample for the game's assets at all tested resolutions.

The GPU's clock speeds are also a factor. With a base clock of 2310 MHz and a boost clock of 2610 MHz, the RTX 4070 Ti is able to sustain high performance under load. The 40.09 TFLOPS of FP32 compute power is a key metric for this game, as it directly translates to the ability to process the complex lighting and particle effects that Doom is known for. The benchmark results for the GPU show a strong DirectX 12 performance with a passmark score of 116, and a Vulkan score of 186784 in Geekbench, which is relevant given Doom's use of the Vulkan API.

The GPU's percentile ranking of 85 indicates it is a high-end part, and its performance in this game reflects that. The data shows that the GPU is the primary determinant of frame rates, especially at 1440p and 4K. The consistent scaling of FPS with resolution and settings is a direct result of the GPU's workload. The RTX 4070 Ti is clearly well-suited for Doom, providing a smooth and responsive experience that is only limited by the display's refresh rate and the user's preference for visual quality. Its end-of-life production status doesn't diminish its current performance in this title.
