Doom

The Intel Core i5-14600KF paired with the NVIDIA GeForce RTX 5080 delivers a decisive performance class for Doom, with measured frame rates at every resolution and preset combination far exceeding the 60 FPS playability threshold. The data shows a system that scales cleanly from 1080p to 4K, maintaining triple-digit average frame rates even under maximum load, positioning this combo as a high-end solution for one of the genre's most technically demanding titles.

Measured FPS Breakdown

At 3840x2160, the combo produces a 107 FPS average on High settings, with the Low preset reaching 146 FPS and Medium hitting 127 FPS. The Ultra preset still holds a solid 88 FPS average, though it is the only 4K configuration that dips below the triple-digit mark. The Medium preset at 4K shows a minimum of 108 FPS and a maximum of 146 FPS, indicating a tight frame time distribution with no severe drops.

Moving to 2560x1440, the performance envelope expands considerably. High settings yield a 198 FPS average, while Low reaches 269 FPS and Medium produces 235 FPS. The Ultra preset at this resolution delivers 162 FPS, which is still more than 2.7 times the 60 FPS threshold. The Medium preset shows a minimum of 199 FPS and a maximum of 270 FPS, demonstrating that even the lowest frame rates at 1440p are more than triple the playability baseline.

At 1920x1080, the data reveals near-maximum performance for the engine. High settings average 306 FPS, Low reaches 416 FPS, and Medium hits 363 FPS. The Ultra preset at 1080p remains exceptionally high at 250 FPS average. The Medium preset's frame range spans from 308 FPS minimum to 417 FPS maximum, showing that the bottleneck at this resolution has shifted almost entirely away from the GPU, with the CPU's 5.30 GHz boost clock and 14 cores providing ample headroom.

The scaling between presets is consistent across resolutions. At 4K, the delta from Low to Ultra is 58 FPS (146 to 88), while at 1440p it is 107 FPS (269 to 162), and at 1080p it is 166 FPS (416 to 250). This progression indicates that lower resolutions amplify the impact of preset changes, as the GPU has more spare capacity to respond to settings adjustments.

Similar Performance Alternatives

The CPU's nearest rival in aggregate benchmark score is the AMD Ryzen 9 7900, which sits just 0.3% behind the i5-14600KF. The AMD Ryzen 7 PRO 5755G trails by 0.4%, while the Intel Core Ultra 5 245 is 0.8% slower. On the higher side, the AMD Ryzen AI Max+ 388 outperforms this chip by 0.8%. These deltas are all within 1%, meaning that swapping the i5-14600KF for any of these processors would produce statistically indistinguishable frame rates in Doom, assuming the GPU remains constant.

For the GPU, the AMD Radeon 8060S is the closest match at 0.6% behind the RTX 5080, followed by the AMD Radeon RX 6750 GRE 12 GB at 0.7% behind. The AMD Radeon Pro W5700X trails by 2.3%, while the AMD Radeon RX 9070 GRE leads by 2.2%. These delta percentages suggest that the RTX 5080's measured FPS in Doom would be nearly identical if paired with any of these alternative graphics cards, with the RX 9070 GRE potentially producing slightly higher frame rates and the Pro W5700X marginally lower ones.

The practical implication for benchmarking is that this combo sits in a tight performance cluster. A user with a Ryzen 9 7900 and an RX 9070 GRE would see effectively the same Doom experience, with differences likely confined to a few frames per second at most. The 0.8% CPU delta and 2.2% GPU delta combine for a worst-case variation of roughly 3% between the top and bottom of the full rival set.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is Ultra, which averages 88 FPS. This is the optimal choice for 4K users seeking maximum visual fidelity, as it clears the 60 FPS threshold by 28 frames. The High preset at 107 FPS and Medium at 127 FPS are also viable, but Ultra offers the highest image quality without sacrificing playability.

For 2560x1440, Ultra again qualifies, with an average of 162 FPS. This represents a 102 FPS margin over the 60 FPS baseline, making it the clear recommendation for 1440p displays. The High preset at 198 FPS and Medium at 235 FPS are available for users prioritizing frame rate over visual detail, but the Ultra preset's 162 FPS average leaves substantial headroom for any future driver or game updates.

At 1920x1080, Ultra remains the top choice with a 250 FPS average. This is 190 FPS above the playability threshold, meaning that even the most demanding preset at 1080p delivers a frame rate that is more than four times the minimum requirement. Users with high-refresh-rate monitors, such as 240 Hz or 360 Hz panels, will find the High preset at 306 FPS or Medium at 363 FPS more suitable for exploiting the display's full potential, but Ultra still provides an exceptionally smooth experience.

The Verdict

This PC can run Doom at every tested resolution and preset combination, with no configuration falling below the 60 FPS playability threshold. The verdict data confirms that all four presets — Low, Medium, High, and Ultra — are playable at 3840x2160, 2560x1440, and 1920x1080.

At 4K, the best settings are Ultra, producing an 88 FPS average. This is a strong result, as it indicates that maximum graphical quality is achievable at the highest resolution without compromise. At 1440p, Ultra delivers 162 FPS, and at 1080p, Ultra hits 250 FPS. The system clears the 60 FPS bar by a minimum of 28 FPS (at 4K Ultra) and by as much as 190 FPS (at 1080p Ultra).

The performance headroom is substantial across the board. Even the weakest configuration — 4K Ultra — runs at nearly 1.5 times the threshold. For competitive play or high-refresh-rate displays, users can drop to High or Medium settings to achieve frame rates ranging from 107 FPS to 146 FPS at 4K, or 198 FPS to 269 FPS at 1440p, and 306 FPS to 416 FPS at 1080p.

CPU and GPU Roles

The data reveals a shifting balance between CPU and GPU influence depending on resolution. At 3840x2160, the GPU is the primary constraint. The frame rate drops from 146 FPS at Low to 88 FPS at Ultra, a 40% reduction, indicating that the RTX 5080's workload scales heavily with preset complexity. The CPU's 14 cores and 20 threads provide sufficient throughput to feed the GPU at this resolution, as evidenced by the consistent frame times in the Medium preset (108 FPS minimum vs 146 FPS maximum).

At 2560x1440, the GPU still dominates, but the CPU's role becomes more visible. The Low preset reaches 269 FPS, which is likely approaching the engine's draw call limit or the CPU's single-thread performance ceiling. The Ultra preset at 162 FPS shows the GPU still has capacity, but the gap between Low and Ultra (107 FPS) is proportionally smaller than at 4K, suggesting that the CPU begins to cap the maximum achievable frame rate at lower resolutions.

At 1920x1080, the CPU becomes the clear bottleneck. The Low preset's 416 FPS average is exceptional, but the High preset's 306 FPS and Ultra's 250 FPS show that the GPU is no longer the limiting factor. The scaling from Low to Ultra at 1080p is 166 FPS, which is the largest absolute delta across all resolutions, but the relative performance ceiling is dictated by the CPU's ability to issue draw calls and manage game logic. The i5-14600KF's 5.30 GHz boost clock and strong single-core performance (4594 in Cinebench R23 single-core) are what enable these high frame rates, though the data suggests that a faster CPU could push the Low preset even higher.

The practical takeaway is that GPU upgrades matter most for 4K performance, while CPU upgrades have diminishing returns at 1440p and are nearly irrelevant at 1080p, where the RTX 5080 is rarely the limiting factor.
