Doom

The Intel Core i9-14900K paired with the NVIDIA GeForce RTX 4080 delivers overwhelming performance in Doom, with measured frame rates that far exceed the 60 FPS playable threshold at every resolution and preset combination tested. The data shows a system that is not merely capable of running the game, but one that crushes it with substantial headroom, making it suitable for high-refresh-rate displays even at maximum settings.

Measured FPS Breakdown

At 3840x2160 (4K), the combination produces an average of 104 FPS on High settings. Dropping to Medium yields 123 FPS average, with a minimum of 104 FPS and a maximum of 141 FPS. Low settings push the average up to 141 FPS, while the most demanding Ultra preset still maintains a strong 85 FPS average. The spread between Low and Ultra at 4K is 56 FPS, indicating that visual quality settings have a meaningful but not crippling impact on performance at this resolution.

Moving to 2560x1440 (1440p), the frame rates scale dramatically. High settings deliver 191 FPS average, Medium reaches 226 FPS with a minimum of 192 FPS and maximum of 260 FPS, and Low produces 260 FPS average. Ultra settings remain exceptionally smooth at 156 FPS average. The jump from 4K to 1440p represents a gain of roughly 87% at High settings, from 104 FPS to 191 FPS, showing how resolution reduction unlocks substantial additional performance.

At 1920x1080 (1080p), the system approaches the limits of what the game engine can deliver. High settings average 295 FPS, Medium hits 350 FPS with a minimum of 297 FPS and maximum of 402 FPS, Low reaches 401 FPS average, and Ultra still holds 241 FPS. The 1080p Medium data shows a 105 FPS spread between minimum and maximum, suggesting some scene-dependent variation but with the floor still far above any playability concern. Across all resolutions, the pattern is consistent: the RTX 4080 and i9-14900K combination never dips below 85 FPS average, even under the heaviest load of 4K Ultra.

CPU and GPU Roles

The performance scaling between resolutions reveals how each component contributes to Doom's frame rates. At 4K, the GPU is the dominant factor. The RTX 4080's raw throughput, with 9728 shading units and 716.8 GB/s memory bandwidth, must fill the massive pixel count of 3840x2160. The difference between Low and Ultra at 4K is 56 FPS (141 down to 85), showing that the GPU bears the brunt of increased graphical load. The i9-14900K, with its 24 cores and 32 threads, has ample headroom at this resolution, as evidenced by the fact that even the most demanding preset stays above 85 FPS.

At 1440p, the balance shifts slightly. The GPU still handles the primary rendering load, but the CPU's high single-thread performance, demonstrated by its Geekbench single-core score of 2655 and Cinebench R23 single-core score of 2262.5, becomes more relevant as frame rates climb toward 200-260 FPS. The scaling from 4K to 1440p at High settings (104 to 191 FPS) shows a 87 FPS gain, which is proportionally larger than the resolution pixel reduction alone would suggest, indicating that the CPU is now feeding the GPU frames more efficiently.

At 1080p, the CPU's role expands significantly. With frame rates reaching 401 FPS on Low settings, the i9-14900K's ability to maintain high instruction throughput becomes critical. The 1080p Medium data shows a minimum of 297 FPS and maximum of 402 FPS, a 105 FPS variance that reflects scene complexity changes where the CPU must process game logic and physics. The Ultra preset at 1080p still yields 241 FPS, meaning neither component becomes a bottleneck severe enough to threaten playability. Across all resolutions, the data indicates that the GPU drives performance at higher resolutions, while the CPU increasingly contributes as resolution drops and frame rates soar.

Best Settings per Resolution

At 3840x2160, the most demanding preset that maintains at least 60 FPS is Ultra, which achieves 85 FPS average. This is the optimal choice for maximum visual fidelity at 4K, as it provides 25 FPS of headroom above the playable threshold. High settings would yield 104 FPS for those prioritizing higher refresh rates, but Ultra offers the best visual experience within the playable envelope.

For 2560x1440, Ultra settings again represent the best choice, delivering 156 FPS average. This comfortably exceeds the 60 FPS threshold while providing the highest quality graphics. The 1440p Ultra setting is particularly compelling because it offers high visual quality at frame rates that suit 144Hz displays. Users with 165Hz or 240Hz monitors could also consider High settings at 191 FPS, but Ultra remains the data-supported recommendation for balancing quality and performance.

At 1920x1080, Ultra settings produce 241 FPS average, making it the clear choice. This preset delivers maximum quality while still achieving frame rates that exceed all but the most extreme refresh rate displays. The 241 FPS average at 1080p Ultra means the system has enough performance to drive 240Hz monitors without compromise. For users with 360Hz displays, dropping to High at 295 FPS or Medium at 350 FPS would unlock higher frame rates, but the standard recommendation is Ultra given its 241 FPS average.

The Verdict

The verdict by resolution is unambiguous: this PC can run Doom at every resolution and setting combination tested. At 3840x2160, all four presets — Ultra, High, Medium, and Low — are playable, with Ultra delivering 85 FPS average. The 2560x1440 resolution similarly supports all settings, with Ultra at 156 FPS average. At 1920x1080, Ultra achieves 241 FPS average, and even the most demanding settings never dip below the 60 FPS threshold. The comboRankInGame of 215 out of 3712 places this system in the upper echelon of tested configurations. With the i9-14900K at the 95th CPU percentile and the RTX 4080 at the 86th GPU percentile, the hardware demonstrates that it is not just sufficient for Doom, but overwhelmingly so. The minimum recorded average FPS across all tests is 85, which means this system could maintain smooth gameplay even with significant background load or future game updates. For any display up to 4K resolution, this configuration provides a definitive answer: yes, it runs Doom exceptionally well.
