GPU Role

The NVIDIA GeForce RTX 5080 serves as the primary performance driver in this configuration, especially at higher resolutions. The GPU's architecture, Blackwell 2.0, manufactured on a 5 nm process by TSMC, contains 45,600 million transistors across a 378 mm² die. With a base clock of 2295 MHz and a boost clock of 2617 MHz, the RTX 5080 operates at high frequencies that translate directly into the frame rates observed in Doom.

The memory subsystem is particularly noteworthy for this game. The RTX 5080 carries 16 GB of GDDR7 memory on a 256-bit bus, yielding a bandwidth of 960.0 GB/s. This bandwidth ensures that texture streaming and geometry data transfer do not become bottlenecks, even when the game is running at 4K resolution with higher preset levels. The GPU also features 10752 shading units, 336 texture mapping units, and 112 raster output units, with a pixel rate of 293.1 GPixel/s and a texture rate of 879.3 GTexel/s. These specifications support the GPU's FP32 performance of 56.28 TFLOPS.

In Doom specifically, the RTX 5080's role becomes more pronounced as resolution increases. At 1080p, the GPU is capable of producing frame rates well above 300 FPS at most settings, which suggests the CPU is keeping pace. At 4K, the GPU's compute and memory resources are more heavily taxed, and the frame rates drop accordingly. The data shows that at 4K Ultra, the average FPS falls to 88, indicating that the GPU is the limiting component at this resolution and settings combination. Conversely, at 1080p Low, the 381 FPS average suggests that the GPU still has headroom, and the CPU's performance becomes more relevant.

Resolution Scaling

The measured FPS data reveals how Doom's performance scales across the three tested resolutions. Starting at 1920x1080 with Low settings, the combo produces 381 FPS. Moving to 2560x1440 at the same settings, the average drops to 269 FPS, a reduction of 112 FPS or approximately 29.4%. At 3840x2160 Low, the average further drops to 146 FPS, which is 61.7% lower than the 1080p result.

The scaling pattern is consistent across other settings levels. For High settings, the progression goes from 306 FPS at 1080p to 198 FPS at 1440p to 107 FPS at 4K. Medium settings show 363 FPS at 1080p, 235 FPS at 1440p, and 127 FPS at 4K. Ultra settings produce 250 FPS at 1080p, 162 FPS at 1440p, and 88 FPS at 4K.

These numbers indicate that the RTX 5080's performance scales roughly with pixel count, but the drop from 1080p to 4K is slightly less than the 4x pixel increase would suggest for a purely GPU-bound scenario. The fact that 1080p Ultra (250 FPS) is higher than 4K Low (146 FPS) by 104 FPS confirms that resolution has a dramatic impact. The limiting component shifts between resolutions: at 1080p, the frame rates are so high that CPU limitations may begin to appear, while at 4K, the GPU is clearly the bottleneck, as evidenced by the larger FPS gaps between settings at that resolution.

Settings Recommendations

The measured rows allow for a direct comparison of the four settings presets at each resolution. At 1920x1080, the differences between Low (381 FPS), Medium (363 FPS), High (306 FPS), and Ultra (250 FPS) are relatively modest in absolute terms, with all presets delivering well above 240 FPS. The gap between Low and Ultra is 131 FPS, but even the lowest Ultra result of 250 FPS is more than sufficient for smooth gameplay.

At 2560x1440, the spread widens: Low produces 269 FPS, Medium 235 FPS, High 198 FPS, and Ultra 162 FPS. The difference between Low and Ultra is 107 FPS. All presets remain above 144 FPS, meaning that even Ultra settings provide a high-refresh-rate experience at this resolution.

At 3840x2160, the differences become more significant. Low yields 146 FPS, Medium 127 FPS, High 107 FPS, and Ultra drops to 88 FPS. The gap between Low and Ultra is 58 FPS. For 4K gaming, the Medium preset at 127 FPS offers a strong balance, as it provides a 19 FPS improvement over High while remaining well above 60 FPS. The Ultra preset at 88 FPS is still playable but represents a substantial 39 FPS drop from Low.

Looking at the data as a whole, the Medium preset appears to be the sweet spot for this combo across all resolutions. At 1080p Medium, the 363 FPS average is within 18 FPS of Low, while at 4K Medium, the 127 FPS average is 39 FPS higher than Ultra. The measured minimum FPS for Medium settings also shows consistency: 308 FPS at 1080p, 199 FPS at 1440p, and 108 FPS at 4K, indicating stable frame delivery without severe dips.

How This Combo Ranks

The combination of the Intel Core i5-13400F and NVIDIA GeForce RTX 5080 achieves a rank of 200 out of 3712 tested combos in Doom. This places the pairing in the top 5.4% of all configurations tested for this game. The rank reflects the strong overall performance of both components working together.

The CPU's contribution to this ranking is supported by its synthetic benchmark scores. The i5-13400F achieves an average benchmark score of 25292, with a percentile rank of 77 among all CPUs. Its nearest rivals in synthetic testing include the AMD Ryzen 9 6900HS (25284, 0% delta), the Intel Core 5 120 (25362, -0.3% delta), and the AMD Ryzen 5 5600X3D (25365, -0.3% delta). These scores indicate that the i5-13400F is a mid-to-upper-tier CPU that does not bottleneck the RTX 5080 in Doom.

The GPU side shows even stronger relative performance. The RTX 5080 has a percentile rank of 87 among all GPUs, with an average benchmark score of 56083. Its nearest rivals are the AMD Radeon 8060S (55757, 0.6% delta), the AMD Radeon RX 6750 GRE 12 GB (55698, 0.7% delta), and the AMD Radeon RX 9070 GRE (57367, -2.2% delta). The RTX 5080's high percentile rank and benchmark scores contribute significantly to the combo's overall position at rank 200.

Measured FPS Breakdown

The complete measured FPS dataset for this combo in Doom is as follows:

At 3840x2160 resolution, the High preset produces an average of 107 FPS. The Low preset yields 146 FPS. The Medium preset averages 127 FPS with a minimum of 108 FPS and a maximum of 146 FPS. The Ultra preset drops to 88 FPS.

At 2560x1440 resolution, the High preset averages 198 FPS. The Low preset reaches 269 FPS. The Medium preset averages 235 FPS with a minimum of 199 FPS and a maximum of 270 FPS. The Ultra preset averages 162 FPS.

At 1920x1080 resolution, the High preset averages 306 FPS. The Low preset reaches 381 FPS. The Medium preset averages 363 FPS with a minimum of 308 FPS and a maximum of 417 FPS. The Ultra preset averages 250 FPS.

The data shows a consistent pattern where Low settings always produce the highest average FPS, followed by Medium, then High, with Ultra producing the lowest results. The measured minimum FPS values for Medium settings across all three resolutions (108, 199, and 308 FPS) indicate that frame pacing remains stable even when the GPU is under load. The maximum FPS values at Medium settings (146, 270, and 417) show that the system can burst well above the average, which is typical for a game like Doom with variable scene complexity.

CPU Role

The Intel Core i5-13400F plays a supporting role in this configuration, providing the computational foundation for the RTX 5080 to operate. The CPU features 10 cores and 16 threads, based on the Raptor Lake architecture on a 10 nm process. Its base clock is 2.50 GHz with a boost clock of 4.60 GHz, and it carries a TDP of 65 W. The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache.

In Doom, the CPU's role is most evident at lower resolutions where frame rates are extremely high. At 1080p Low, the average FPS of 381 requires the CPU to feed the GPU with draw calls and game logic updates at a very rapid pace. The i5-13400F's 16 threads and 4.60 GHz boost clock provide sufficient single-thread and multi-thread performance to sustain these rates. The CPU's synthetic benchmarks support this: it scores 960 in 3DMark single-thread, 1880 in 3DMark 2-thread, and 7314 in 3DMark 16-thread tests. Cinebench R23 scores show 3191 single-core and 22604 multi-core, while Geekbench scores are 1996 single-core and 11068 multi-core.

The CPU's nearest rivals in synthetic benchmarks are all within a narrow band. The AMD Ryzen 9 6900HS matches the i5-13400F's average score exactly (0% delta), while the Intel Core 5 120 and AMD Ryzen 5 5600X3D are both 0.3% lower, and the AMD Ryzen 7 6800H is 0.4% higher. This suggests that the i5-13400F provides consistent mid-range CPU performance that does not become a limiting factor in Doom.

As resolution increases, the CPU's role diminishes relative to the GPU. At 4K Ultra, the 88 FPS average is clearly GPU-limited, as the RTX 5080's rendering workload dominates. The CPU's 20 MB of L3 cache and dual-channel memory support for both DDR4 and DDR5 help maintain smooth data flow, but the benchmark results indicate that the GPU is the primary determinant of frame rates at higher resolutions.
