Doom

Resolution Scaling

The measured frame rates across resolutions reveal a GPU-bound workload that scales predictably with pixel count, though the Core i7-14700F keeps pace well enough that the RTX 4080 SUPER remains the primary limiter at every step. Dropping from 1080p to 1440p at High settings reduces average FPS from 291.8 to 189.0, a 35% performance hit, while moving from 1440p to 4K at High brings the average down to 103.5, another 45% reduction. This steep scaling curve is classic GPU-bound behavior — the 4080 SUPER's render throughput is being exhausted as pixel count rises, and the CPU is not holding it back.

At Low settings, the scaling is even more revealing. The 1080p Low result of 400.4 FPS drops to 257.9 FPS at 1440p (a 36% reduction), then to 139.0 FPS at 4K (a 46% further drop). The fact that 4K Low still delivers 139.0 FPS — more than the 1080p Ultra result of 238.3 FPS — indicates that the GPU's raw pixel-pushing capability is the dominant factor. If the CPU were the bottleneck, we would expect diminishing returns at lower resolutions; instead, the 1080p Low score of 400.4 FPS suggests the i7-14700F's 20 cores and 5.40 GHz boost clock are sufficient to feed the GPU even at extremely high frame rates.

The gap between settings narrows as resolution increases, which is typical. At 1080p, the spread from Low (400.4 FPS) to Ultra (238.3 FPS) is 162.1 FPS, a 68% difference. At 4K, the same spread is only 57.1 FPS (139.0 vs 81.9), a 70% relative difference but a smaller absolute gap. This compression at 4K confirms that the GPU's shading units and memory bandwidth are saturated before settings can fully express their cost. The 4080 SUPER's 736.3 GB/s bandwidth and 52.22 TFLOPS FP32 throughput are being pushed to their limits at 4K Ultra, where the average drops to 81.9 FPS — still smooth for most displays, but the data clearly shows the ceiling.

GPU Role

The RTX 4080 SUPER's specifications directly explain its performance profile in Doom. The GPU carries 16 GB of GDDR6X memory on a 256-bit bus, yielding 736.3 GB/s of bandwidth — ample for this game's texture streaming at all tested resolutions. The 10240 shading units operating at a boost clock of 2550 MHz produce 52.22 TFLOPS of FP32 compute, which is the engine driving the high frame rates observed. The 80 RT cores and 320 tensor cores are present but Doom (2016) does not leverage ray tracing or DLSS in these measurements, so the rasterization throughput of the 112 ROPs at 285.6 GPixel/s is what matters most here.

The GPU's percentile ranking of 88 versus all GPUs places it in the upper tier, and its nearest rivals show it trading blows at the top. The 4080 SUPER's average benchmark score of 53610 is just 0.2% ahead of the AMD Radeon RX 6900 XT (53489) and 0.4% ahead of the AMD Radeon Pro W6600M (53414). Against the NVIDIA GeForce RTX 5070 Ti (52086), the 4080 SUPER leads by 2.9%. These margins are small in synthetic tests, but in Doom the measured FPS shows the 4080 SUPER is decisively capable — 4K Ultra at 81.9 FPS is a strong result for a title of this era, and 1080p Low at 400.4 FPS demonstrates headroom far beyond typical display refresh rates.

The 5 nm process node from TSMC, housing 45,900 million transistors on a 379 mm² die, contributes to the efficiency that allows such high clocks without excessive power draw. The 320 W TDP and triple-slot cooler are the physical cost of this performance, but the data shows the GPU delivers consistent frame rates across all settings, with no anomalous drops that would indicate thermal throttling or memory constraints.

How This Combo Ranks

In the database of 1681 tested combinations, this pairing of the Intel Core i7-14700F with the NVIDIA GeForce RTX 4080 SUPER ranks 102nd overall for Doom. That places it in the top 6% of all tested combos, a strong showing that reflects both components' high individual percentiles — the CPU at 94th percentile and the GPU at 88th percentile. The rank of 102 out of 1681 means there are 101 combos that achieve higher average FPS in this game, but those are almost certainly pairs of even more extreme hardware (e.g., RTX 4090-class GPUs with flagship CPUs).

The CPU's nearest rivals in synthetic benchmarks provide context for why this combo performs as it does. The i7-14700F scores 54097 on average, which is just 0.6% behind the AMD Ryzen 9 9900X (54450) and 1.1% behind the AMD Ryzen 9 9900X3D (54681). It beats the Intel Xeon Phi 7290 (53469) by 1.2% and the AMD EPYC 7313P (53206) by 1.7%. These tiny deltas mean the 14700F is essentially at parity with top-tier multi-core CPUs, so the combo's 102nd rank is primarily determined by the GPU's ceiling rather than any CPU deficiency. In Doom, which is not heavily multi-threaded, the 14700F's 20 cores are more than sufficient, and the rank reflects that the GPU is the limiting factor.

Measured FPS Breakdown

At 1920x1080, the data shows a wide range depending on settings. Low settings produce 400.4 FPS average, Medium drops to 350.7 FPS, High reduces to 291.8 FPS, and Ultra settles at 238.3 FPS. These numbers indicate that even at Ultra, the combo is far beyond the 144 Hz refresh rate of most monitors, leaving massive headroom for competitive play or future game updates.

At 2560x1440, the results are still very high. Low delivers 257.9 FPS, Medium 228.1 FPS, High 189.0 FPS, and Ultra 155.6 FPS. The Ultra result at 1440p is notable because it stays above 144 FPS, making this resolution and settings combination ideal for high-refresh-rate 1440p displays. The step from High to Ultra at 1440p costs 33.4 FPS (189.0 to 155.6), a 17.7% reduction, which is a reasonable trade for the visual uplift.

At 3840x2160, the performance remains playable but the ceiling becomes visible. Low yields 139.0 FPS, Medium 121.0 FPS, High 103.5 FPS, and Ultra 81.9 FPS. The Ultra result at 4K is the only configuration in the measured set that falls below 100 FPS, but 81.9 FPS is still smooth for a single-player FPS. The scaling from High to Ultra at 4K costs 21.6 FPS (103.5 to 81.9), a 20.9% drop, which is the largest relative penalty across all resolutions for that settings step — indicating that Ultra's extra effects (likely shadows and post-processing) are particularly demanding at 4K pixel counts.

Settings Recommendations

For 4K displays, the data suggests High settings (103.5 FPS) as the sweet spot — it delivers a 26.4% improvement over Ultra (81.9 FPS) while maintaining visual fidelity. Medium (121.0 FPS) is a viable fallback if frame rate is prioritized, offering a 17% uplift over High. Low (139.0 FPS) is unnecessary at 4K unless targeting 120 Hz+ refresh rates, but the visual degradation is unlikely to be worth it.

For 1440p, Ultra (155.6 FPS) is the recommended choice because it stays above the 144 Hz mark that most 1440p gaming monitors target. If a 165 Hz or 240 Hz display is in use, High (189.0 FPS) or Medium (228.1 FPS) provide the extra headroom. There is little reason to drop below High at this resolution, as the game remains highly playable.

For 1080p, all settings exceed 238 FPS, so the decision is purely visual. Ultra (238.3 FPS) is the best experience, and the 162.1 FPS gap to Low (400.4 FPS) is irrelevant for any consumer display. The data shows no scenario at 1080p where the GPU is stressed enough to warrant lowering settings, making Ultra the clear choice.

CPU Role

The Intel Core i7-14700F brings 20 cores and 28 threads, split between performance and efficiency cores on the Raptor Lake-R architecture, with a base clock of 2.10 GHz and a boost of 5.40 GHz. The 33 MB of shared L3 cache and 2 MB L2 per core provide ample data locality for game logic, while the 65 W TDP (though the boost state draws more) keeps thermals manageable. In Doom, which is not heavily threaded, the CPU's single-core performance is what matters most — the Cinebench R23 single-core score of 5003 and Geekbench single-core score of 2711 indicate strong per-thread capability.

The CPU's average benchmark score of 54097 places it at the 94th percentile of all CPUs, with nearest rivals showing it is within 1.1% of the AMD Ryzen 9 9900X3D (54681) and 0.6% of the Ryzen 9 9900X (54450). This parity means the 14700F is not leaving performance on the table in Doom. The measured FPS at 1080p Low (400.4 FPS) is a strong indicator that the CPU can feed the GPU even at extreme frame rates; if the CPU were insufficient, we would see a plateau at lower resolutions. The data does not show such a plateau — the scaling from 1080p to 1440p to 4K is smooth and proportional, confirming the CPU is not the limiting component in any tested configuration.

The 5.40 GHz boost clock is particularly relevant for a game like Doom that relies on high IPC and clock speed for its Vulkan renderer. The 14700F's single-threaded Cinebench R20 score of 2101 and R15 score of 504 support this, showing it can sustain high clocks under load. The result is that the combo's 102nd rank out of 1681 is attributable to the GPU's ceiling, not the CPU. At 4K Ultra (81.9 FPS), the GPU is clearly saturated, while the CPU still has headroom — evidenced by the fact that lowering settings at 4K improves FPS (139.0 FPS at Low), which would not happen if the CPU were the bottleneck.
