Doom

Resolution Scaling

The measured FPS data for Doom with the Intel Core i5-13400F and NVIDIA GeForce RTX 4070 SUPER reveals a clear pattern of diminishing returns as resolution climbs. At 1080p with Low settings, the combo produces 350.3 FPS, but dropping to 1440p Low reduces that to 228.8 FPS — a 34.7% performance hit. Moving from 1440p Low to 4K Low yields 123.5 FPS, another 46.0% reduction. This scaling curve is steep, suggesting that at lower resolutions the system is heavily CPU-bound, while at 4K the GPU becomes the primary constraint.

The resolution scaling behavior changes character when examining Ultra settings. At 1080p Ultra, the system hits 207.6 FPS; at 1440p Ultra it falls to 136.2 FPS; at 4K Ultra it drops further to 73.7 FPS. The percentage losses between each step are 34.4% and 45.9% respectively — nearly identical to the Low settings deltas. This consistency across quality presets indicates that Doom's engine scales predictably with pixel count, regardless of the graphical workload being applied. The RTX 4070 SUPER's 12 GB of GDDR6X memory and 504.2 GB/s bandwidth appear sufficient to avoid memory bottlenecks even at 4K, as the FPS reductions track resolution rather than texture or effect complexity.

What is particularly telling is the gap between Low and Ultra at each resolution. At 1080p, the spread is 142.7 FPS (from 350.3 down to 207.6). At 1440p, that spread narrows to 92.6 FPS. At 4K, it shrinks to 49.8 FPS. This compression of the settings delta at higher resolutions is classic GPU-bound behavior — the graphics card is working near its limits at 4K, so additional graphical features have less relative impact on frame rate. The data suggests that for this game, the RTX 4070 SUPER is the limiting component at 4K, while the i5-13400F's 10 cores and 16 threads become the bottleneck at 1080p.

GPU Role

The RTX 4070 SUPER's specifications paint a picture of a GPU designed for high-refresh gaming. Its boost clock of 2475 MHz, combined with 7168 shading units, delivers 35.48 TFLOPS of FP32 compute. The 56 RT cores and 224 tensor cores provide hardware acceleration for ray tracing and DLSS features, though the measured FPS data here reflects standard rasterization performance. The 12 GB VRAM on a 192-bit bus provides 504.2 GB/s of bandwidth, which is ample for Doom's 2016-era engine at any resolution tested.

The GPU's benchmark positioning is strong: it achieves an avgBenchmarkScore of 42576, placing it in the 84th percentile of all GPUs. Its nearest rivals show remarkably close scores — the NVIDIA RTX A6000 is just 0.2% behind, and the AMD Radeon RX 7650 GRE trails by 0.3%. This tight clustering suggests the RTX 4070 SUPER sits at a performance plateau where small architectural differences matter more than raw specifications.

In Doom specifically, the GPU's role becomes more pronounced as resolution increases. The 4K Ultra result of 73.7 FPS is the only measured configuration below 90 FPS, indicating that the card's limits are reached only at the most demanding settings. At 1080p, the GPU is clearly not the constraint — the 350.3 FPS Low result shows headroom that the CPU cannot feed. The GPU's 220 W TDP and dual-slot cooler design suggest sustained performance is maintained without thermal throttling, though the measured data does not include thermal metrics to confirm this directly.

How This Combo Ranks

The combo rank of 287 out of 1681 tested combinations places this system in the top 17.1% of all CPU-GPU pairings tested in Doom. This percentile positioning is strong, though not elite — the top 286 combos achieve higher average FPS across the tested configurations. Given that the RTX 4070 SUPER sits at the 84th GPU percentile and the i5-13400F at the 82nd CPU percentile, the combined ranking aligns closely with what the individual component percentiles would predict.

The CPU's nearest rivals provide context for its contribution to this ranking. The Intel Core i7-13620H scores within 0.1% of the i5-13400F's avgBenchmarkScore of 25236, while the AMD Ryzen 5 5600X3D is 0.5% faster and the AMD EPYC 9474F is 0.5% slower. These near-identical scores suggest that the i5-13400F's performance is well-established at its tier, and swapping it for any of these rivals would produce negligible changes in Doom's frame rates. The GPU's nearest rivals — RTX A6000, RX 7650 GRE, Radeon Pro 580X, and Tesla M40 — all fall within 1.6% of the RTX 4070 SUPER's score, further indicating that this combo's ranking is representative of a broad performance class rather than a unique pairing.

Settings Recommendations

Examining the measured FPS rows, the Medium preset offers the most balanced experience across resolutions. At 1080p Medium, the system produces 302.7 FPS — comfortably above any display refresh rate currently on the market. At 1440p Medium, 198.4 FPS still provides headroom for 144 Hz displays. Even at 4K Medium, 107.4 FPS exceeds the 60 FPS threshold for smooth gameplay on standard 4K monitors.

The High preset is the next best option, delivering 255.4 FPS at 1080p, 168.2 FPS at 1440p, and 91.1 FPS at 4K. The step from Medium to High costs 47.3 FPS at 1080p, 30.2 FPS at 1440p, and 16.3 FPS at 4K. These penalties are modest relative to the visual improvements High typically provides over Medium. The Ultra preset, by contrast, exacts a heavier toll: dropping to 207.6 FPS at 1080p, 136.2 FPS at 1440p, and 73.7 FPS at 4K. The 4K Ultra result is the only configuration that approaches the 60 FPS minimum for competitive play, making it a risky choice for high-refresh 4K displays.

For users prioritizing maximum frame rates at 1080p, the Low preset's 350.3 FPS is the clear winner, though the visual compromise is substantial. The data indicates that Medium is the sweet spot for most users, with High being a viable alternative for those with 144 Hz or 165 Hz displays at 1440p.

Measured FPS Breakdown

At 1920x1080, the full settings spectrum shows the system's range: Low produces 350.3 FPS, Medium reaches 302.7 FPS, High achieves 255.4 FPS, and Ultra delivers 207.6 FPS. Each settings tier costs roughly 45-48 FPS compared to the previous tier, with the Low-to-Medium gap being the largest at 47.6 FPS.

At 2560x1440, the results scale down proportionally: Low hits 228.8 FPS, Medium reaches 198.4 FPS, High achieves 168.2 FPS, and Ultra delivers 136.2 FPS. The differences between tiers here are 30.4 FPS (Low to Medium), 30.2 FPS (Medium to High), and 32.0 FPS (High to Ultra) — remarkably consistent steps that indicate the GPU is handling each settings change with similar efficiency.

At 3840x2160, the performance envelope tightens: Low produces 123.5 FPS, Medium reaches 107.4 FPS, High achieves 91.1 FPS, and Ultra delivers 73.7 FPS. The tier-to-tier differences are 16.1 FPS, 16.3 FPS, and 17.4 FPS respectively. The consistency of these gaps across all three resolutions suggests a well-optimized engine with predictable scaling, though the absolute frame rates at 4K Ultra (73.7 FPS) indicate that this combo is best suited for 1080p or 1440p gaming if Ultra settings are desired.

CPU Role

The Intel Core i5-13400F's 10 cores and 16 threads, operating at base clocks of 2.50 GHz and boost clocks of 4.60 GHz, provide substantial compute headroom for Doom's engine. The CPU's benchmark results are solid: Cinebench R23 multicore scores 21279, while single-core reaches 3004. Geekbench multicore hits 10971 and single-core 2301. These figures place the CPU at the 82nd percentile of all CPUs, with an avgBenchmarkScore of 25236.

The CPU's nearest rivals demonstrate that its performance is tightly clustered. The Intel Core i7-13620H scores 25201 (0.1% faster), the AMD Ryzen 5 5600X3D scores 25365 (0.5% faster), and the AMD EPYC 9474F scores 25103 (0.5% slower). This grouping suggests that Doom's performance is not highly sensitive to CPU choice within this performance tier — the differences between these processors would translate to only a few FPS in the measured configurations.

The CPU's 65 W TDP and DDR4/DDR5 dual-channel memory support indicate a power-efficient design that can sustain high clocks without excessive thermal demands. The 20 MB shared L3 cache and 1.25 MB per-core L2 cache provide adequate data locality for game workloads. At 1080p, where the CPU is likely the bottleneck given the 350.3 FPS Low result, the i5-13400F's single-thread performance of 3004 in Cinebench R23 single-core proves sufficient to drive frame rates far beyond display refresh rate capabilities.
