GPU Role

The AMD Radeon RX 7800 XT is the primary driver of frame rates in Doom. Its 16 GB of GDDR6 memory and 624.1 GB/s bandwidth provide ample headroom for texture streaming and high-resolution assets. The GPU's boost clock of 2430 MHz and game clock of 2124 MHz reflect its RDNA 3.0 architecture, built on a 5 nm process from TSMC.

The benchmark results show the GPU's capability scaling with settings. At 1080p, the gap between Low (279.8 FPS) and Ultra (171.8 FPS) is 108 FPS, demonstrating how rendering load increases with quality presets. The GPU's 3,840 shading units and 96 ROPs handle the rasterization workload, while its 60 ray accelerators (RT cores) are present but not heavily utilized in this title, given it launched in 2016 before ray tracing became standard.

At 4K, the GPU's role becomes more pronounced. The difference between Ultra (58.5 FPS) and Low (97.7 FPS) at 3840x2160 is 39.2 FPS, a smaller absolute gap than at 1080p but still significant. The GPU's 233.3 GPixel/s pixel rate and 583.2 GTexel/s texture rate are the key specifications for understanding these results — they define how quickly the card can fill the screen and apply textures, which directly impacts the measured frame rates.

The GPU's aggregate benchmark score of 32,619 places it at the 76th percentile. Its nearest rival, the AMD FirePro S9300 X2, scores 32,540 (0.2% delta), while the NVIDIA P104-100 scores 32,747 (-0.4% delta). This indicates the RX 7800 XT is well within a tight performance band among its immediate competitors, though the delta percentages are small enough that real-world gaming results may vary by title.

CPU Role

The Intel Core i5-11400F provides the processing foundation for this combo. With 6 cores and 12 threads, it offers decent multi-threading for a 2021 desktop processor. Its base clock of 2.60 GHz and boost clock of 4.40 GHz are the key figures for single-threaded performance, which matters in Doom's engine that relies on a mix of main-thread work and parallel tasks.

The CPU's cache hierarchy — 80 KB L1 per core, 512 KB L2 per core, and 12 MB shared L3 — helps feed the GPU with draw calls and game logic. In benchmark tests, the CPU achieves a Cinebench R23 multi-core score of 14,372 and a single-core score of 2,029. Its 3DMark scores range from 868 (single-thread) to 5,652 (max threads), showing scaling across thread counts.

The CPU's percentile ranking of 75 versus all CPUs, with an average benchmark score of 17,181, places it near the AMD Ryzen 7 5700U (17,189, 0% delta) and Intel Core i7-1260P (17,212, -0.2% delta). These rivals are mobile or low-power parts, yet they match the i5-11400F's aggregate performance, suggesting the desktop chip's advantage is not in raw throughput but in sustained operation.

In Doom specifically, the CPU's role is to maintain frame pacing and avoid bottlenecking the GPU. At 1080p Low, the combo hits 279.8 FPS, which is well beyond typical display refresh rates. The CPU's 12 threads handle the game's physics, AI, and scripting, while its single-thread performance (PassMark single-thread score of 2,981) ensures the main game thread does not become a limiting factor at lower resolutions.

How This Combo Ranks

The Intel Core i5-11400F and AMD Radeon RX 7800 XT combination ranks 641st out of 1,681 tested combos in Doom. This places it in the 62nd percentile of all combos tested for this game — a solid mid-to-upper tier position, though not at the very top of the database.

The ranking reflects a balance between the CPU's 75th percentile and the GPU's 76th percentile individual standings. The combo performs slightly below what either component's percentile might suggest alone, indicating some degree of bottleneck or overhead in this specific title. The 1,681 total combos include configurations with newer CPUs and higher-end GPUs, so a 641st rank is respectable given the i5-11400F is from the 11th generation Core series.

The data shows that this combo is well-matched for 1440p gaming, where it achieves between 108.4 (Ultra) and 182.9 (Low) FPS. At 4K, it remains playable at High settings (72.3 FPS) but dips below 60 FPS at Ultra (58.5 FPS). The ranking would likely improve if the CPU were newer, but the GPU's strong showing at lower resolutions keeps the overall position competitive.

Resolution Scaling

The measured FPS data reveals how this combo scales across resolutions. From 1080p to 1440p, the average FPS drop across all settings is notable: at High settings, it falls from 206.4 to 132.7 (a 35.7% reduction); at Low, from 279.8 to 182.9 (34.6% reduction); at Medium, from 245.4 to 158.1 (35.6% reduction); and at Ultra, from 171.8 to 108.4 (36.9% reduction). These consistent drops indicate that the GPU is the primary scaling factor, as the pixel count increase from 1080p to 1440p is roughly 78% more pixels, but the FPS drops by about a third.

Moving from 1440p to 4K shows a different pattern. At High settings, FPS drops from 132.7 to 72.3 (45.5% reduction); at Low, from 182.9 to 97.7 (46.6% reduction); at Medium, from 158.1 to 83.8 (47.0% reduction); and at Ultra, from 108.4 to 58.5 (46.0% reduction). The 4K resolution has 2.25 times the pixels of 1440p, yet the FPS reduction is less than half, suggesting the GPU's memory bandwidth and compute resources are sufficient to partially mitigate the pixel increase.

The limiting component shifts as resolution increases. At 1080p and 1440p, the CPU's single-thread performance and the game's engine overhead become relatively more important, as evidenced by the high FPS figures (up to 279.8 at 1080p Low). At 4K, the GPU's rendering throughput becomes the clear bottleneck, with the Ultra preset at 58.5 FPS showing the card's limits under maximum load.

Measured FPS Breakdown

At 1920x1080, the combo delivers high frame rates across all settings. Low settings produce 279.8 FPS, Medium 245.4 FPS, High 206.4 FPS, and Ultra 171.8 FPS. The step from Low to Medium is 34.4 FPS, from Medium to High is 39 FPS, and from High to Ultra is 34.6 FPS, showing relatively even scaling.

At 2560x1440, the results remain strong. Low settings achieve 182.9 FPS, Medium 158.1 FPS, High 132.7 FPS, and Ultra 108.4 FPS. The setting-to-setting differences are 24.8 FPS (Low to Medium), 25.4 FPS (Medium to High), and 24.3 FPS (High to Ultra), maintaining a consistent drop of roughly 25 FPS per quality tier.

At 3840x2160, the frame rates become more modest. Low settings deliver 97.7 FPS, Medium 83.8 FPS, High 72.3 FPS, and Ultra 58.5 FPS. The deltas here are 13.9 FPS (Low to Medium), 11.5 FPS (Medium to High), and 13.8 FPS (High to Ultra), indicating that the GPU is becoming saturated and each additional setting step has a smaller absolute impact.

The data shows that this combo is best suited for 1080p and 1440p gaming, where it exceeds 100 FPS at all settings except 1440p Ultra (108.4 FPS, which still clears 100). At 4K, it remains playable at High (72.3 FPS) and Medium (83.8 FPS), but Ultra dips to 58.5 FPS, which is just below the 60 FPS threshold many consider the minimum for smooth gameplay. The measured FPS values align with the GPU's 76th percentile standing, showing strong performance in a well-optimized engine like Doom's id Tech 6.
