Doom

The Intel Core i5-11400F paired with the NVIDIA GeForce RTX 4080 SUPER combination ranks 163rd out of 1681 tested combos in Doom, placing it in the top 10% of all configurations. This is a formidable standing for a mid-range CPU from 2021 paired with a flagship-tier GPU, and the benchmark data confirms that the combo is remarkably well-balanced for this title, with the GPU doing the heavy lifting at higher resolutions while the CPU keeps pace at 1080p.

How This Combo Ranks

With a combo rank of 163 out of 1681, this pairing sits comfortably in the upper echelon of tested systems for Doom. The rank reflects the synergy between the i5-11400F and the RTX 4080 SUPER, where neither component becomes a severe bottleneck in this particular game. The CPU itself holds a 75th percentile ranking among all processors, with an average benchmark score of 17181. Its nearest rivals in synthetic tests are the AMD Ryzen 7 5700U (avg score 17189, delta 0%), the Intel Core i7-1260P (avg score 17212, delta -0.2%), and the Intel Core Ultra 7 164U (avg score 17215, delta -0.2%). These deltas are negligible, indicating that the i5-11400F's computational throughput is essentially on par with those mobile-oriented chips, despite being a desktop part. In Doom, however, the combination's rank is what matters, and the measured FPS data shows this system dominating the vast majority of the field. The fact that it sits at 163 of 1681 suggests that only systems with newer, higher-core-count CPUs and equally powerful GPUs manage to outperform it, and even then, the margin is likely small given the game's optimization.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is the undisputed performance driver in this combo. Its 16 GB of GDDR6X memory on a 256-bit bus provides 736.3 GB/s of bandwidth, which is crucial for feeding the GPU's 10240 shading units at high resolutions. The card's base clock of 2295 MHz and boost clock of 2550 MHz are the physical clocks that translate into the raw throughput measured in the FPS data. The GPU's average benchmark score of 53610 places it in the 88th percentile of all GPUs, and its nearest rivals include the AMD Radeon RX 6900 XT (avg score 53489, delta 0.2%) and the AMD Radeon Pro W6600M (avg score 53414, delta 0.4%). The delta of 0.2% over the RX 6900 XT is essentially a tie in synthetic tests, but in Doom, the RTX 4080 SUPER's architecture, with 80 RT cores and 320 Tensor cores, provides the headroom needed for the high refresh rates seen in the measured data. The GPU's 52.22 TFLOPS of FP32 performance is the theoretical ceiling, and the measured FPS shows it approaching that limit at lower resolutions, while at 4K, the memory bandwidth and pixel rate (285.6 GPixel/s) become the limiting factors.

Settings Recommendations

The measured FPS data offers a clear picture of which preset provides the best experience. At 3840x2160, the High preset delivers 104.1 FPS average, which is excellent for a smooth 4K experience, while Ultra drops to 85.3 FPS. The Medium preset at 121 FPS is the sweet spot for 4K if the user prioritizes frame rate over visual fidelity, but High is the recommended starting point because it maintains a triple-digit average without the steep performance penalty of Ultra. At 2560x1440, the High preset achieves 188.4 FPS, which is ideal for high-refresh-rate monitors, while Ultra still manages 154.2 FPS. For 1080p, the Low preset hits 314.5 FPS, but the High preset at 281.9 FPS is the best balance for competitive play, as it provides a massive frame rate while retaining visual quality. The data suggests that High is the universally recommended preset across all resolutions, as it offers the most consistent performance without sacrificing the game's visual impact. Ultra is only worth considering at 1440p and below, where the frame rate remains above 150 FPS.

Measured FPS Breakdown

The measured FPS data across all resolutions and settings shows a consistent scaling pattern. At 1920x1080, the Low preset yields 314.5 FPS, Medium 298.1 FPS, High 281.9 FPS, and Ultra 238.4 FPS. The delta between Low and Ultra is 76.1 FPS, indicating that even at the most demanding settings, the system is heavily GPU-bound at 1080p, with the CPU i5-11400F providing enough single-threaded performance to avoid becoming a bottleneck. Moving to 2560x1440, the numbers drop to 258.9 FPS (Low), 224.8 FPS (Medium), 188.4 FPS (High), and 154.2 FPS (Ultra). The gap between Low and Ultra narrows to 104.7 FPS in absolute terms, but the percentage drop is similar, showing that the GPU is still the primary limiter. At 3840x2160, the performance curve flattens: Low yields 139.4 FPS, Medium 121 FPS, High 104.1 FPS, and Ultra 85.3 FPS. The delta between Low and Ultra here is 54.1 FPS, which is the smallest absolute gap across all resolutions, confirming that the GPU is fully saturated at 4K. The most telling data point is the High preset at 4K (104.1 FPS) versus the High preset at 1080p (281.9 FPS), which shows a 177.8 FPS drop when resolution quadruples.

Resolution Scaling

The FPS drop from 1080p to 4K reveals the limiting component with clarity. At the Low preset, the system goes from 314.5 FPS at 1080p to 139.4 FPS at 4K, a 55.7% reduction. At the High preset, the drop is from 281.9 FPS to 104.1 FPS, a 63.1% reduction. At Ultra, the drop is from 238.4 FPS to 85.3 FPS, a 64.2% reduction. The consistent ~60% performance loss when quadrupling the pixel count (from 1080p to 4K) is a classic sign of a GPU-bound scenario. If the CPU were the limiting factor, the FPS would stay relatively flat across resolutions, but the data shows a sharp decline, meaning the RTX 4080 SUPER's compute and memory bandwidth are being taxed more heavily as resolution increases. The i5-11400F, with its 6 cores and 12 threads boosting to 4.40 GHz, is sufficient to feed the GPU at 1080p High, but at 4K, the GPU's 736.3 GB/s bandwidth and 52.22 TFLOPS of FP32 become the ceiling. The fact that the 4K Ultra average (85.3 FPS) is still above 60 FPS indicates that this combo is not just playable but genuinely fast at maximum settings, with the GPU architecture (Ada Lovelace) efficiently handling the game's Vulkan API. The measured data confirms that the RTX 4080 SUPER is the dominant partner in this relationship, and the i5-11400F is a capable companion that does not hold it back until the very lowest settings at 1080p, where the CPU's single-thread score of 868 in 3DMark may begin to limit the frame rate.
