Doom

The Intel Core i5-14400F pairs a 10-core, 16-thread Raptor Lake design with a 2.50 GHz base and 4.70 GHz boost clock. This combination of physical cores and high single-thread headroom is directly relevant to Doom’s engine, which typically scales well with both. The data shows that at 1080p Low, this combo reaches 262 fps, indicating the CPU’s multi-core throughput (Cinebench R23 multi-core score of 21914) is more than sufficient to feed the GPU in lightly threaded scenarios. The 20 MB of shared L3 cache and dual-channel DDR4/DDR5 memory support further reduce potential bottlenecks, though the measured results suggest the GPU becomes the primary constraint as resolution climbs. The CPU’s 88th percentile ranking among all tested processors supports the notion that it is a high-end part, but the game’s performance ceiling here is dictated more by the graphics card than the processor.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-14400F’s architecture (Raptor Lake, 10 nm process) provides 10 cores and 16 threads, with a boost clock of 4.70 GHz. In Doom, a fast-paced FPS, the single-core performance is critical for maintaining high frame rates. The processor’s Cinebench R23 single-core score of 3093 indicates strong per-thread capability, which translates directly to the 262 fps observed at 1080p Low. At that setting, the GPU is not the limiting factor, and the CPU’s ability to process game logic and draw calls quickly is what allows such high output.

Multi-core performance also matters, as Doom can utilize multiple threads for rendering tasks. The CPU’s Cinebench R23 multi-core score of 21914, paired with a PassMark multithread score of 25783, suggests ample headroom. However, the benchmark results reveal a clear pattern: as resolution increases from 1080p to 4K, the average FPS drops significantly even when settings remain constant. For instance, at High settings, the FPS falls from 191.4 at 1080p to 121 at 1440p, then to 64.3 at 4K. This steep decline is not a CPU limitation; it reflects the GPU’s workload. The CPU’s percentile rank of 88% versus all CPUs, and its near-identical average benchmark score (32508) to rivals like the Intel Core i7-12800H (32513, 0% delta), confirms it is a capable processor that will not bottleneck this game at standard resolutions.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i5-14400F and NVIDIA GeForce RTX 3070 ranks 784th out of 1681 tested combos in Doom. This places it in the upper-middle tier of the database, slightly above the median. The ranking is influenced by the GPU’s 72nd percentile among all GPUs, while the CPU sits at the 88th percentile. The imbalance suggests that the RTX 3070 is the weaker link in this pairing for this specific title. The GPU’s average benchmark score (28238) is much lower than the CPU’s (32508), indicating that the graphics card limits overall system performance in most scenarios. Compared to its nearest GPU rivals, the RTX 3070’s score is 0.9% higher than the AMD Radeon RX 6600 XT (27985) and 1% higher than the NVIDIA GeForce GTX 980 Ti (27956), but 0.6% lower than the AMD FirePro S7150 (28409). This narrow margin at the GPU level explains why the combo rank is not higher; the processor has more headroom than the graphics card can utilize.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data shows a consistent and predictable scaling pattern across resolutions. At Low settings, the average FPS drops from 262 at 1080p to 168.7 at 1440p (a 35.6% reduction), and then to 93.9 at 4K (a 44.3% reduction from 1440p). At High settings, the drop is steeper: from 191.4 at 1080p to 121 at 1440p (36.8% loss), and then to 64.3 at 4K (46.9% loss from 1440p). This indicates that the GPU is the primary bottleneck at higher resolutions. The CPU’s performance is relatively constant, so the FPS decline is directly proportional to the increase in pixel count and shading work. The data suggests that at 1080p, the system is partially CPU-bound at lower settings, but at 4K, the GPU is fully saturated. For example, the 4K Ultra setting yields 54.9 fps, which is a 79% drop from the 1080p Ultra result of 154.2 fps. This scaling behavior is typical for a mid-range GPU like the RTX 3070, which has 8 GB of GDDR6 memory and a 448.0 GB/s bandwidth.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the combo delivers excellent performance across all presets. The Low setting produces 262 fps, Medium yields 224.8 fps, High achieves 191.4 fps, and Ultra drops to 154.2 fps. These numbers are all well above the 144 Hz refresh rate common on gaming monitors, so the CPU is not limiting here. Moving to 2560x1440, the performance remains strong: Low hits 168.7 fps, Medium reaches 148.1 fps, High manages 121 fps, and Ultra drops to 99.2 fps. The step from High to Ultra at 1440p costs 21.8 fps, showing that the Ultra preset’s additional effects are expensive. At 3840x2160, the GPU becomes the clear bottleneck. Low averages 93.9 fps, Medium falls to 77.6 fps, High drops to 64.3 fps, and Ultra bottoms out at 54.9 fps. The gap between Low and Ultra at 4K is 39 fps, which is a 41.5% performance penalty. These results indicate that the RTX 3070’s 8 GB VRAM is sufficient for 4K, but the raw compute power (20.31 TFLOPS FP32) is not enough to maintain high frame rates with maximum settings.

Settings Recommendations

For the best experience, the data suggests prioritizing frame rate over visual fidelity. At 1080p, the Ultra preset (154.2 fps) is the best choice because it provides a high frame rate with the highest visual quality. At 1440p, the High preset (121 fps) offers a good balance, as Ultra (99.2 fps) is still smooth but the performance gap to High is notable. At 4K, the High preset (64.3 fps) is the only option that stays above 60 fps, while Ultra (54.9 fps) may cause noticeable stutter on a 60 Hz display. The Low preset at 4K (93.9 fps) is also viable if the user prefers maximum smoothness over visual details. The Medium preset is a middle ground, providing 77.6 fps at 4K, which is above 60 fps but sacrifices more visual quality than High. Overall, the recommendation is to use High settings for a consistent experience across all resolutions, as it provides the best compromise between image quality and performance.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3070, based on the GA104 chip and Ampere architecture, has 8 GB of GDDR6 memory on a 256-bit bus, yielding a bandwidth of 448.0 GB/s. The memory clock is 1750 MHz (14 Gbps effective), and the boost clock is 1725 MHz. In Doom, the VRAM capacity is not a limiting factor at 4K, as the game’s textures fit within 8 GB. The GPU’s compute capabilities, measured at 20.31 TFLOPS FP32, are the primary driver of the performance drops seen at higher resolutions. The pixel rate of 165.6 GPixel/s and texture rate of 317.4 GTexel/s determine how quickly the GPU can fill pixels and sample textures. The data shows that at 4K Ultra, the GPU runs out of steam, producing only 54.9 fps. The RTX 3070’s 72nd percentile ranking among all GPUs and its average benchmark score of 28238 place it as a solid mid-range card. Compared to its nearest rivals, it is only marginally faster than the RX 6600 XT, so its performance in this game is expected to be moderate. The GPU’s 8 GB memory is also a consideration for future titles, but for Doom, the measured results indicate that the core clock and shader count (5888 shading units) are what matter most.
