This analysis breaks down the measured results to explain exactly what each component contributes and how to configure the game for the best experience.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor built on the Zen 4 Raphael architecture. It operates on a 5 nm process from TSMC and runs with a base clock of 3.70 GHz and a boost clock of 4.70 GHz. The processor includes 64 KB of L1 cache per core, 1 MB of L2 cache per core, and a shared 32 MB L3 cache. This configuration, combined with DDR5 memory support and a dual-channel memory bus delivering 83.2 GB/s of bandwidth, provides the foundation for the high frame rates seen in the measured data.

In synthetic benchmarks, the Ryzen 5 7400F posts a Cinebench R23 multicore score of 21765 and a single-core score of 3072. Its Passmark single-thread score of 3689 and multithread score of 25645 further illustrate its balanced performance profile. The processor sits at the 83rd percentile of all CPUs, with an average benchmark score of 32750. Compared to its nearest rivals, it is effectively neck-and-neck with the Intel Core i5-14600T, which scores 32707 (a 0.1% delta), and the AMD Ryzen 7 PRO 6850H, which scores 32812 (a -0.2% delta). The Ryzen 5 7400F also edges out the Intel Core Ultra 7 155H by 0.2% and the AMD Ryzen AI 7 PRO 360 by 0.3%.

For Doom, the CPU's role becomes evident when examining the frame rate scaling across resolutions. At 1920x1080 with Low settings, the system achieves 385 FPS, which is a substantial jump from the 287 FPS seen at 2560x1440 and the 156 FPS at 3840x2160 at the same settings. This scaling pattern indicates that the CPU is capable of feeding the GPU with enough data to reach very high frame rates, but the GPU becomes the limiting factor as resolution increases. The 6-core, 12-thread configuration is more than sufficient for this game, as the measured FPS does not appear to be bottlenecked by the processor at any settings level tested. The high single-core performance, reflected in the Cinebench R15 single-core score of 309, is likely a key factor in maintaining smooth gameplay during intense action sequences.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear and predictable scaling pattern as resolution increases. At 1920x1080, the system is capable of producing extremely high frame rates, with averages ranging from 267 FPS at Ultra settings to 385 FPS at Low settings. Moving to 2560x1440, these numbers drop to 173 FPS at Ultra and 287 FPS at Low. At 3840x2160, the averages fall further to 94 FPS at Ultra and 156 FPS at Low.

Analyzing the percentage drops between resolutions is instructive. For High settings, the transition from 1080p to 1440p sees a drop from 327 FPS to 211 FPS, a 35.5% decrease. From 1440p to 4K, the drop is from 211 FPS to 115 FPS, a 45.5% decrease. For Low settings, the drop from 1080p to 1440p is from 385 FPS to 287 FPS (25.5% decrease), and from 1440p to 4K it is from 287 FPS to 156 FPS (45.6% decrease).

The pattern is consistent: the frame rate loss is more pronounced when moving from 1440p to 4K than from 1080p to 1440p. This indicates that the RTX 4090 is the limiting component at higher resolutions. The GPU's rendering load increases quadratically with resolution, and the data suggests that at 4K, the GPU is working near its maximum capacity for this game, even with the powerful 7400F feeding it. Conversely, the relatively smaller drops at 1080p indicate that the CPU is able to keep up with the GPU's demands, and the bottleneck shifts more toward the GPU as pixel count increases. The fact that the system still averages 94 FPS at 4K Ultra demonstrates that this pairing is capable of high-refresh-rate 4K gaming, though not at the extreme frame rates achievable at lower resolutions.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

1920x1080: At this resolution, the system delivers its highest frame rates. Low settings produce an average of 385 FPS, the highest recorded in the dataset. Medium settings yield 367 FPS, with a minimum of 312 FPS and a maximum of 422 FPS. High settings average 327 FPS, and Ultra settings drop to 267 FPS. The spread between Low and Ultra is 118 FPS, showing that the game's settings have a moderate impact on performance at this resolution, but even the lowest preset is far beyond what standard 60 Hz or 144 Hz monitors can display.

2560x1440: This is the resolution where the system's performance starts to become more relevant for high-refresh-rate gaming. Low settings average 287 FPS, while Medium settings average 250 FPS, with a minimum of 213 FPS and a maximum of 288 FPS. High settings produce 211 FPS, and Ultra settings average 173 FPS. The gap between Low and Ultra here is 114 FPS, nearly identical to the 1080p spread, indicating that the GPU is still not the primary limiter at this resolution for these settings.

3840x2160: At 4K, the RTX 4090 becomes the clear bottleneck. Low settings average 156 FPS, Medium settings average 136 FPS with a minimum of 115 FPS and a maximum of 156 FPS. High settings drop to 115 FPS, and Ultra settings average 94 FPS. The difference between Low and Ultra at this resolution is 62 FPS, which is a much smaller absolute gap compared to lower resolutions. This suggests that the GPU is saturated and the settings have a reduced relative impact on performance, as the rendering load is already very high.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4090 is the dominant component in this pairing. It is built on the Ada Lovelace architecture with a 5 nm process and features 76,300 million transistors on a 609 mm² die. The GPU operates with a base clock of 2235 MHz and a boost clock of 2520 MHz, with memory running at 1313 MHz (21 Gbps effective). It is equipped with 24 GB of GDDR6X memory on a 384-bit bus, delivering a massive 1.01 TB/s of memory bandwidth.

In synthetic benchmarks, the RTX 4090 scores 38194 in Passmark G3D and 26613 in Passmark GPU Compute. Its 3DMark Steel Nomad DX12 score is 9223, and it achieves 255416 in Geekbench OpenCL and 271631 in Geekbench Vulkan. The GPU sits at the 88th percentile of all GPUs, with an average benchmark score of 60347. Its nearest rival, the Intel Arc Pro A60, scores 60326 (a 0% delta), and the AMD Radeon Pro Vega 48 scores 60140 (a 0.3% delta). The AMD Radeon Pro W6600M scores 61896, which is 2.5% higher, and the AMD Radeon PRO V710 scores 58657, which is 2.9% lower.

For Doom, the RTX 4090's role is to drive frame rates at high resolutions. The measured data shows that at 4K Ultra, the system averages 94 FPS, which is below the 115 FPS average at 4K High. This indicates that the game's Ultra preset places a significant load on the GPU. The 24 GB VRAM is far more than Doom requires, so memory capacity is not a limiting factor. The GPU's high memory bandwidth and compute throughput are the key specifications that allow it to maintain playable frame rates at 4K, even with the most demanding settings. The data shows that the RTX 4090 is fully utilized at 4K, but at 1080p, the CPU's performance ceiling becomes apparent, as the GPU is capable of producing even more frames than the current measurements show.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured FPS data provides a clear picture of how each settings preset performs across the three tested resolutions. The primary goal for any PC builder is to achieve a frame rate that matches their display's refresh rate while maintaining visual quality. For this system, the recommendations vary significantly by resolution.

At 1920x1080, all settings presets deliver frame rates well above 240 FPS. The lowest average is 267 FPS at Ultra, which is still exceptionally high. The data shows that Medium settings provide 367 FPS, which is a 37% increase over Ultra while likely offering a visual quality that is nearly indistinguishable at this resolution on most monitors. Given the high frame rates, the recommendation is to use Ultra settings if the display supports very high refresh rates (240 Hz or more), but Medium or High settings are preferable for maximizing frame rate headroom and ensuring consistent minimum FPS. The minimum FPS at Medium is 312, which is better than the average FPS of many other systems.

At 2560x1440, the situation is similar but with a bit more nuance. Ultra settings average 173 FPS, which is still high and suitable for 144 Hz to 165 Hz displays. High settings average 211 FPS, which is ideal for 240 Hz displays. Medium settings average 250 FPS, providing a substantial buffer above any common refresh rate. For the best balance of visual fidelity and performance, High settings are recommended, as they offer a 38 FPS advantage over Ultra while the visual difference between High and Ultra is often minimal in fast-paced action. For competitive play, Medium settings at 250 FPS provide an even smoother experience.

At 3840x2160, the GPU is the limiting factor. Ultra settings average 94 FPS, which is below the 120 Hz threshold that many high-end 4K displays support. High settings average 115 FPS, which is a significant improvement and crosses the 100 FPS mark. Medium settings average 136 FPS, with a minimum of 115 FPS. For a 4K gaming experience, High settings are the recommended choice, as they provide a 21 FPS average increase over Ultra and likely result in a visually similar experience. Medium settings are the best option for those prioritizing frame rate consistency, as they offer a 42 FPS advantage over Ultra. The data suggests that Ultra settings at 4K are only suitable for users with 90 Hz displays who prioritize maximum visual quality over smoothness.
