GPU Role

The NVIDIA GeForce GTX 1080 Ti is built on the Pascal architecture with a 16 nm process node from TSMC, containing 11,800 million transistors on a 471 mm² die. Its base clock runs at 1481 MHz with a boost clock of 1582 MHz, while memory operates at 1376 MHz (11 Gbps effective). The 11 GB GDDR5X memory pool, paired with a 352-bit bus, delivers 484.4 GB/s of bandwidth — a critical asset for Doom's fast-paced texture streaming at higher resolutions.

The GPU's shading capacity is substantial: 3,584 shading units, 224 texture mapping units, and 88 raster output pipelines. This translates to a pixel rate of 139.2 GPixel/s and a texture rate of 354.4 GTexel/s, with FP32 performance rated at 11.34 TFLOPS. These specifications explain why the GPU handles Doom's id Tech engine so effectively — the engine's emphasis on high-throughput rendering aligns well with the GTX 1080 Ti's raw compute strengths.

In Doom specifically, the GPU's 88 ROPs prove particularly valuable at 4K resolution, where pixel fill requirements increase dramatically. The measured FPS data confirms this: at 3840x2160, the GPU delivers 55 FPS on High settings, showing that the 11 GB frame buffer and 484.4 GB/s bandwidth prevent memory-related stutters even at maximum resolution. The GTX 1080 Ti's end-of-life production status doesn't diminish its capability in this title, as the benchmark results demonstrate consistent performance across all settings presets.

Resolution Scaling

The performance drop from 1080p to 4K reveals a classic GPU-bound scenario, with the GTX 1080 Ti becoming increasingly stressed as pixel count grows. At Ultra settings, average FPS declines from 128 at 1920x1080 to 86.1 at 2560x1440 (a 32.7% reduction), then to 47.9 at 3840x2160 (a 62.6% reduction from 1080p). This scaling pattern indicates that the GPU's compute and memory bandwidth are the limiting factors, not the CPU.

The scaling curve steepens dramatically at 4K across all settings. At Low settings, the combo achieves 216.7 FPS at 1080p, 141.6 FPS at 1440p, and 75.8 FPS at 4K — meaning 4K Low runs at 65% of 1440p Low performance. At High settings, the progression is 160.8 FPS (1080p), 101 FPS (1440p), and 55 FPS (4K). The relative drop from 1440p to 4K is consistent across presets: approximately 45-46% for Low, High, and Ultra, and 46.6% for Medium. This uniformity confirms the GPU is the sole bottleneck at higher resolutions.

Notably, the i5-13400F's capabilities are not exhausted even at 1080p Low, where 216.7 FPS is achieved. The CPU's 10 cores and 16 threads, with a boost clock of 4.60 GHz, provide sufficient single-thread and multi-thread performance to keep pace with the GTX 1080 Ti's frame output. The data shows no evidence of CPU limitation at any tested resolution or settings combination.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results across all presets. Low settings produce 216.7 FPS average, Medium reaches 192 FPS, High hits 160.8 FPS, and Ultra maintains 128 FPS. The gap between Low and Ultra is 40.9%, reflecting the GPU's ability to handle increased graphical loads while still staying above 120 FPS at the highest preset.

Moving to 2560x1440, performance remains robust. Low settings average 141.6 FPS, Medium 119.5 FPS, High 101 FPS, and Ultra 86.1 FPS. The drop from 1080p to 1440p ranges from 32.7% (Ultra) to 34.6% (Low), showing consistent scaling behavior. Even at 1440p Ultra, the average FPS of 86.1 exceeds the 60 FPS threshold by 43.5%, making this resolution highly playable.

At 3840x2160, the GPU's limitations become apparent. Low settings average 75.8 FPS, Medium 63.8 FPS, High 55 FPS, and Ultra 47.9 FPS. The Ultra preset falls below 60 FPS, while High barely misses it. Low and Medium both remain above 60 FPS, but the margin narrows considerably compared to lower resolutions. The 4K Ultra result of 47.9 FPS represents a 62.6% reduction from 1080p Ultra, indicating that 4K gaming requires settings compromises for this combination.

How This Combo Ranks

This specific CPU-GPU combination ranks 1000th out of 1681 tested combos in Doom, placing it in the 59.5th percentile of all configurations. This ranking reflects a balanced pairing where neither component drastically bottlenecks the other, though the GPU's age (Pascal architecture, 16 nm process) limits the overall ceiling.

The CPU's individual standing is stronger than the combo's overall rank. The i5-13400F sits in the 82nd percentile among all CPUs with an average benchmark score of 25236, closely matching the Intel Core i7-13620H (25201, 0.1% delta) and AMD Ryzen 5 5600X3D (25365, -0.5% delta). This suggests the CPU could support a more powerful GPU without becoming a limiting factor.

Conversely, the GTX 1080 Ti's 61st percentile ranking among GPUs (average score 19402) aligns more closely with the combo's overall position. The GPU effectively ties with the NVIDIA GeForce GTX 780 (19405, 0% delta) and sits just 1.1% ahead of the NVIDIA TITAN Xp (19184). This indicates the GPU is the performance ceiling for this combo in Doom, and upgrading it would yield immediate FPS improvements.

Settings Recommendations

For 1080p gaming, Ultra settings at 128 FPS are clearly the best choice — the frame rate far exceeds the 60 FPS standard and provides a 32.8% improvement over the next lowest preset (High at 160.8 FPS, which is actually higher but Ultra offers the best visual quality at still-playable speeds). The data shows no reason to compromise at this resolution.

At 1440p, Medium settings (119.5 FPS) offer the best balance of visual quality and performance, providing an 18.3% FPS advantage over High (101 FPS) while remaining visually rich. Ultra at 86.1 FPS is also viable, but Medium provides a more comfortable margin for demanding scenes. Low settings at 141.6 FPS are unnecessary unless maximum refresh rate is prioritized.

For 4K gaming, the recommendation depends on FPS priorities. Low settings (75.8 FPS) ensure smooth gameplay with a 26% margin above 60 FPS, while Medium (63.8 FPS) barely maintains playability. High (55 FPS) and Ultra (47.9 FPS) fall below the 60 FPS threshold, making them less ideal for competitive play. The optimal 4K choice is Low for consistent 60+ FPS performance, with Medium as an acceptable alternative for those prioritizing image quality over frame rate.

CPU Role

The Intel Core i5-13400F features 10 cores and 16 threads, combining 6 performance cores with 4 efficiency cores in a Raptor Lake architecture. Its base clock of 2.50 GHz boosts to 4.60 GHz, with a 65 W TDP and 20 MB of shared L3 cache. The CPU's 3DMark scores demonstrate strong scaling: 1880 in 2-thread, 3459 in 4-thread, 5591 in 8-thread, and 7314 in 16-thread tests, indicating effective multi-threading utilization.

In Doom, the CPU's role is largely supportive — the game's Vulkan-based engine distributes workload efficiently across threads, and the i5-13400F's 16 threads provide ample capacity. Cinebench R23 scores of 21279 (multi-core) and 3004 (single-core) show balanced performance that prevents CPU bottlenecks even at 1080p Low, where the GPU produces 216.7 FPS. The 82nd percentile ranking among all CPUs confirms this processor is well above average for gaming workloads.

The CPU's memory support for both DDR4 and DDR5, along with dual-channel architecture, offers flexibility without affecting Doom performance meaningfully. The 20 MB L3 cache is particularly beneficial for game data access patterns. Given that the GPU's 61st percentile ranking is significantly lower than the CPU's 82nd percentile, the data clearly indicates the GTX 1080 Ti — not the i5-13400F — is the component that limits frame rates in this title. Upgrading the GPU would yield substantial FPS gains, while CPU upgrades would provide minimal improvement in Doom.
