Doom

Resolution Scaling

The measured FPS data for Doom with the Intel Core i5-14400F and NVIDIA GeForce RTX 5070 reveals a clear pattern of GPU-bound scaling as resolution increases. At 1080p with Low settings, the combo delivers 340 FPS, dropping to 216.9 FPS at 1440p and 121.4 FPS at 4K. This represents a 36% reduction from 1080p to 1440p and a 64% reduction from 1080p to 4K at Low settings. The scaling is nearly linear with pixel count, which strongly indicates the RTX 5070 is the limiting component at lower resolutions.

At Ultra settings, the pattern holds but with lower absolute numbers: 207.1 FPS at 1080p, 134.7 FPS at 1440p, and 69.1 FPS at 4K. The 4K Ultra figure is particularly telling — it sits below the 89.8 FPS achieved at 4K High, showing that the Ultra preset imposes a significant rendering cost that the GPU struggles to overcome at high pixel counts. The gap between 4K High and 4K Ultra is 20.7 FPS, while the gap between 1080p High and 1080p Ultra is 44.2 FPS, suggesting the Ultra preset's additional effects scale disproportionately with resolution.

The data implies that at 1080p, the i5-14400F's 10 cores and 16 threads are sufficient to feed the RTX 5070's rendering pipeline, as the FPS numbers exceed typical high-refresh monitor capabilities. At 4K, however, the pixel throughput demands overwhelm the GPU, and the CPU's role diminishes. The 4K Low result of 121.4 FPS versus the 1080p Low result of 340 FPS shows a 218.6 FPS difference — a massive drop that cannot be attributed to CPU limitations, given the CPU's strong single-thread performance in synthetic benchmarks.

FAQ

Q: Does the i5-14400F bottleneck the RTX 5070 at any resolution in Doom?

A: Benchmark results indicate the CPU is not a bottleneck at 4K, where the GPU's pixel throughput limits performance. At 1080p Low, the 340 FPS figure suggests the CPU can keep up, but the relatively smaller gains from 1440p to 1080p (76.9 FPS at Low) versus 4K to 1440p (95.5 FPS at Low) hint that the CPU may start to constrain performance at very high frame rates.

Q: What is the best resolution for competitive play with this combo?

A: The 1080p Low preset yields 340 FPS, providing the highest frame rate headroom for competitive scenarios. The 1440p Low result of 216.9 FPS still exceeds common high-refresh displays, making it viable if visual clarity is preferred over maximum FPS.

Q: How does the Ultra preset compare to High at 4K?

A: At 4K, Ultra averages 69.1 FPS while High averages 89.8 FPS, a difference of 20.7 FPS. The Ultra preset demands significantly more GPU resources, and the 4K Ultra result falls below the 60 FPS threshold commonly considered smooth for single-player experiences.

Q: Is the RTX 5070's 12 GB VRAM sufficient for Doom at 4K Ultra?

A: The measured 69.1 FPS at 4K Ultra indicates the GPU's rendering capabilities, not VRAM capacity, are the limiting factor in this title. The 12 GB GDDR7 memory with 672.0 GB/s bandwidth provides adequate capacity for this game's textures, as evidenced by the playable frame rates across all tested settings.

Q: What does the combo's rank of 322 out of 1681 tell us?

A: This combo places in the top 19th percentile of all tested combinations for Doom, indicating it delivers strong performance relative to the broader database of CPU-GPU pairings.

Q: How does the i5-14400F's performance compare to its nearest rivals in synthetic tests?

A: The CPU's average benchmark score of 32508 is nearly identical to the Intel Core i7-12800H's 32513, with a delta of 0%. It sits 0.2% ahead of the AMD Ryzen 5 PRO 7645 and 0.2% behind the AMD Ryzen 7 250, showing this CPU is well-matched to comparable mid-range parts.

How This Combo Ranks

The Intel Core i5-14400F with NVIDIA GeForce RTX 5070 ranks 322nd out of 1681 tested combos for Doom, placing it in the 80.8th percentile of all combinations. This is a strong result, given that the CPU alone sits in the 88th percentile of all CPUs and the GPU in the 83rd percentile of all GPUs. The combo's rank is slightly lower than either component's individual percentile, suggesting that the pairing may not extract the absolute maximum from both parts in this specific game.

The ranking implies that while this is a high-performing combination, there are 321 other combos that achieve higher average FPS in Doom. Given that the RTX 5070's nearest rivals include the NVIDIA GeForce RTX 3090 (0.6% higher average score) and the AMD Radeon Pro 5300 (0.2% higher), the GPU is competitive with previous-generation high-end parts. The CPU's nearest rival, the Intel Core i7-12800H, has an identical average score, confirming that the i5-14400F delivers performance comparable to a mobile high-end chip.

The rank of 322 suggests that the bottleneck in this combo depends heavily on the resolution and settings chosen. At 4K Ultra, the GPU's 30.87 TFLOPS of FP32 compute is clearly stressed, while at 1080p Low, the CPU's 4.70 GHz boost clock becomes more relevant. The data reveals a well-balanced pairing that performs admirably but does not reach the top tier of combos, likely due to the mid-range positioning of both components.

Settings Recommendations

For the best experience measured in the data, the High preset at 1440p offers an optimal balance: 162.2 FPS average, which exceeds the refresh rate of most high-refresh monitors while maintaining visual quality. At 4K, the High preset's 89.8 FPS is the best choice for visual fidelity without sacrificing smoothness, as the Ultra preset drops to 69.1 FPS. For players prioritizing maximum frame rates, the 1080p Low preset at 340 FPS provides the highest headroom, though the Medium preset at 296.8 FPS is a better visual compromise with only a 43.2 FPS reduction.

The Medium preset consistently outperforms High across all resolutions: 296.8 vs 251.3 FPS at 1080p, 189.6 vs 162.2 FPS at 1440p, and 103.9 vs 89.8 FPS at 4K. This suggests that Medium captures most of the visual benefits of High while reducing GPU load by roughly 13-14% based on the FPS deltas. The Ultra preset, however, shows a significant performance penalty at every resolution, with the 4K Ultra result falling below 70 FPS. Given the data, the recommended settings are Medium at 1440p for a high-refresh experience, or High at 4K for maximum visual quality while maintaining playable frame rates.

Measured FPS Breakdown

At 1080p, the measured results span a wide range: Low averages 340 FPS, Medium averages 296.8 FPS, High averages 251.3 FPS, and Ultra averages 207.1 FPS. The difference between Low and Ultra is 132.9 FPS, representing a 39% reduction from the lowest to highest quality preset. At 1440p, the figures are 216.9 FPS (Low), 189.6 FPS (Medium), 162.2 FPS (High), and 134.7 FPS (Ultra). The spread between Low and Ultra at 1440p is 82.2 FPS, a 38% reduction.

At 4K, the results compress further: Low averages 121.4 FPS, Medium averages 103.9 FPS, High averages 89.8 FPS, and Ultra averages 69.1 FPS. The 4K Low to Ultra delta is 52.3 FPS, a 43% reduction. The data shows that the performance cost of each preset tier is relatively consistent across resolutions, but the absolute FPS penalties shrink as resolution increases, confirming the GPU's growing dominance as the limiting factor. Notably, the 1080p Low result of 340 FPS is the only measured value exceeding 300 FPS, while 4K Ultra at 69.1 FPS is the only value below 70 FPS.

CPU Role

The Intel Core i5-14400F features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. Its 20 MB of shared L3 cache and 1.25 MB per-core L2 cache provide ample data locality for game workloads. In synthetic benchmarks, the CPU achieves a Cinebench R23 multicore score of 21914 and a single-core score of 3093, indicating strong multi-threaded capability and competitive single-thread performance.

In Doom, the CPU's role is most apparent at 1080p Low, where the 340 FPS result approaches the limits of what the GPU can output. The 10-core configuration with 16 threads allows the CPU to handle the game's rendering thread and background tasks without becoming a bottleneck. However, the CPU's percentile ranking of 88th among all CPUs, combined with its average benchmark score of 32508, shows it is a capable but not top-tier part. The data indicates the CPU is sufficient for Doom across all tested settings, as even at 4K Ultra, the FPS is limited by the GPU's 30.87 TFLOPS compute rather than any CPU deficiency.

GPU Role

The NVIDIA GeForce RTX 5070, based on the Blackwell 2.0 architecture with a 5 nm process from TSMC, contains 31,100 million transistors on a 263 mm² die. It features 6144 shading units, 192 texture mapping units, and 80 raster output processors, along with 48 RT cores and 192 tensor cores. The GPU's 12 GB of GDDR7 memory operates at 1750 MHz with a 192-bit bus, delivering 672.0 GB/s of bandwidth. Its boost clock reaches 2512 MHz, enabling 30.87 TFLOPS of FP32 compute.

In Doom, the GPU's performance is the primary driver of the measured FPS across all resolutions. The 4K Ultra result of 69.1 FPS highlights the GPU's struggle with high pixel counts combined with Ultra settings, while the 1080p Low result of 340 FPS demonstrates its raw throughput capability. The GPU's percentile ranking of 83rd among all GPUs and average benchmark score of 41687 place it competitively, with its nearest rival being the NVIDIA GeForce RTX 3090 at 0.6% higher average score. The data suggests the RTX 5070's 12 GB VRAM is not a limiting factor in Doom, as even the most demanding 4K Ultra setting maintains playable frame rates without indication of memory-related stuttering.
