Doom

The Intel Core i5-14400F paired with the NVIDIA GeForce RTX 4080 delivers overwhelming performance in Doom (2016), a game whose fast-paced action benefits from the exceptionally high frame rates this combo produces. The benchmark data, measured across three resolutions and four quality presets, shows this system never dips below 85 frames per second on average, making it a definitive choice for high-refresh-rate displays. The following analysis breaks down the measured performance, contextualizes the hardware within its respective performance tiers, and provides actionable settings guidance based strictly on the empirical data.

Similar Performance Alternatives

The Intel Core i5-14400F sits in a tightly clustered performance band, with its nearest rivals all within a negligible margin of its average benchmark score of 32,279. The closest competitor is the AMD Ryzen 7 PRO 8840U, which scores 32,233, a delta of just 0.1% — meaning these two processors are effectively interchangeable in raw compute throughput. The Intel Core i9-11900 trails by only 0.2% with a score of 32,226, while the AMD Ryzen 7 6800HS is marginally ahead at 32,354, representing a -0.2% delta from the i5-14400F's perspective. The Intel Core i7-12800H rounds out the group with a score of 32,121, a 0.5% deficit. For Doom, which is primarily GPU-bound at higher settings, any of these CPUs would produce nearly identical frame rates, so users upgrading from or considering these alternatives should expect no meaningful difference in gameplay performance.

On the graphics side, the RTX 4080's nearest rival is the NVIDIA GeForce RTX 4080 SUPER, which scores 54,209 versus the RTX 4080's 54,247 — a 0.1% gap that places them in the same performance class. The AMD Radeon Pro W5700X scores 54,828, which is 1.1% higher, while the AMD Radeon RX 6750 GRE 12 GB and AMD Radeon 8060S both score higher still, at 55,698 and 55,757 respectively, representing deltas of -2.6% and -2.7% from the RTX 4080's baseline. These differences are small enough that in Doom, where the RTX 4080 already achieves triple-digit frame rates at 4K, users with any of these GPUs would see broadly similar performance. The RTX 4080 SUPER is particularly noteworthy as a near-identical alternative, with its 0.1% delta indicating that the two cards are effectively the same hardware for practical purposes.

CPU and GPU Roles

The benchmark data for this CPU-GPU combination reveals a system where the RTX 4080 is the dominant performance driver, but the i5-14400F's strong single-threaded capabilities ensure it never becomes a bottleneck. At 1920x1080, the lowest resolution tested, the GPU is less stressed, yet the CPU still delivers average frame rates of 388 FPS on Low settings and 295 FPS on High settings. These figures demonstrate that the i5-14400F, with its 10 cores and 16 threads boosting to 4.70 GHz, can feed the RTX 4080 sufficiently even at CPU-sensitive resolutions.

The scaling between resolutions shows the GPU's workload increasing as pixel count rises. Moving from 1920x1080 to 2560x1440 on High settings, the average FPS drops from 295 to 191, a reduction of approximately 35%. Further scaling to 3840x2160 on the same settings yields 104 FPS, another 45% reduction. This pattern is consistent with GPU-bound behavior: the RTX 4080's 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are being taxed by the increasing pixel throughput. The CPU's role remains constant across resolutions, with the i5-14400F's single-core performance — evidenced by a Cinebench R23 single-core score of 3,055 — being more than adequate for Doom's engine.

Preset scaling further illuminates the GPU's dominance. At 3840x2160, the difference between Low and Ultra settings is substantial: 141 FPS average on Low versus 85 FPS on Ultra, a 40% performance penalty for maximum visual quality. The same pattern holds at 2560x1440, where Low produces 260 FPS and Ultra drops to 156 FPS. At 1920x1080, the spread is 388 FPS on Low versus 241 FPS on Ultra. These numbers indicate that the RTX 4080's shading units (9,728) and texture units (304) are the limiting factor when settings increase, while the CPU's contribution remains relatively flat. For users prioritizing maximum frame rates, the GPU's headroom is best exploited at lower presets, but even at Ultra settings, the system never approaches the 60 FPS playability threshold.

Measured FPS Breakdown

At 3840x2160 resolution, the RTX 4080 and i5-14400F combination delivers consistently high frame rates across all presets. The Low preset produces an average of 141 FPS, while Medium averages 123 FPS with a minimum of 104 FPS and a maximum of 141 FPS. High settings average 104 FPS, and the Ultra preset, the most demanding, averages 85 FPS. Notably, the minimum FPS recorded at this resolution (104 FPS on Medium) is still well above the 60 FPS playability threshold, indicating no significant frame drops under load.

At 2560x1440, performance scales upward substantially. Low settings average 260 FPS, Medium averages 226 FPS with a minimum of 192 FPS and a maximum of 260 FPS, High averages 191 FPS, and Ultra averages 156 FPS. The minimum frame rate at Medium (192 FPS) is higher than the average frame rate at 4K Ultra (85 FPS), illustrating the substantial performance gain from reducing resolution. Even at the most demanding preset, the system maintains an average of 156 FPS, which is more than sufficient for 144 Hz displays.

The 1920x1080 results are predictably the highest of the three resolutions. Low settings achieve an average of 388 FPS, while Medium averages 350 FPS with a minimum of 297 FPS and a maximum of 402 FPS. High settings deliver 295 FPS average, and Ultra still manages 241 FPS. The maximum FPS recorded across all tests, 402 FPS at 1080p Medium, demonstrates that this combination can drive very high refresh rate monitors (240 Hz and above) without compromise. Across all resolutions and presets, the system's minimum recorded frame rate is 104 FPS (4K Medium), which remains far above the playable threshold of 60 FPS.
