Doom

The Intel Core i5-12600KF paired with the NVIDIA GeForce RTX 5080 delivers exceptionally high frame rates in Doom, with every tested preset at every resolution clearing the 60 FPS playable threshold by a wide margin. The data shows a system that is heavily GPU-bound at higher resolutions but still capable of pushing well beyond refresh-rate territory even at 4K, with the most demanding Ultra preset at 3840x2160 still averaging 91.8 FPS.

Measured FPS Breakdown

At 1920x1080, the combination produces triple-digit averages across all settings. The Low preset reaches 410.5 FPS, while Medium drops slightly to 370.4 FPS. High settings yield 311.3 FPS, and Ultra still maintains a substantial 253.5 FPS. The gap between Low and Ultra is 157 FPS, indicating that even the heaviest graphical load at this resolution leaves massive headroom.

Moving to 2560x1440, the scaling is consistent but less extreme. Low settings average 276.3 FPS, Medium hits 239.4 FPS, and High delivers 206.1 FPS. Ultra at this resolution produces 167.9 FPS, which is still more than double the 60 FPS threshold. The difference between Low and Ultra here is 108.4 FPS, showing that the GPU workload increases noticeably but does not threaten playability.

At 3840x2160, the frame rates remain impressive but begin to show the expected strain. Low averages 150.8 FPS, Medium reaches 132.6 FPS, and High drops to 112.9 FPS. Ultra is the only setting below 100 FPS, averaging 91.8 FPS. The spread from Low to Ultra at 4K is 59 FPS, the smallest absolute gap across all resolutions, suggesting that pixel throughput becomes a limiting factor rather than pure shading complexity.

No minimum or maximum FPS data is provided in the measured results, so the analysis relies solely on average frame rates. The absence of min/max values means the data cannot fully characterize frame time consistency or stutter behavior, but the averages are so far above the playable threshold that even substantial dips would likely remain playable.

CPU and GPU Roles

The scaling between resolutions and presets reveals a clear division of labor. At 1920x1080, the CPU's role is more prominent, as evidenced by the large frame rate jumps when lowering settings. The difference between Low and Ultra at 1080p is 157 FPS, which indicates that the RTX 5080 has enough spare throughput to respond strongly to reduced graphical load. However, the i5-12600KF with its 10 cores and 16 threads still manages to feed the GPU adequately, as no preset falls below 253.5 FPS.

At 2560x1440, the GPU begins to take on more responsibility. The spread between Low and Ultra narrows to 108.4 FPS, showing that the render target size starts to constrain the GPU's ability to translate lower settings into linearly higher frame rates. The CPU is still not the bottleneck here, since even the most demanding preset at this resolution exceeds 167.9 FPS.

At 3840x2160, the GPU becomes the dominant factor. The frame rate difference between Low and Ultra shrinks to 59 FPS, and the absolute numbers drop significantly. This pattern indicates that pixel fill rate and memory bandwidth — the RTX 5080's 960.0 GB/s GDDR7 on a 256-bit bus — are the primary constraints at 4K. The CPU's influence diminishes as the GPU spends more time on rasterization and less time waiting for draw calls.

The benchmark data suggests that this pairing is balanced for Doom at 1440p and below, where the CPU can keep up with the GPU's output. At 4K, the GPU is clearly the limiting component, but the i5-12600KF still provides enough single-thread performance — evidenced by its 3DMark single-thread score of 1016 and Cinebench R23 single-core score of 3302 — to avoid becoming a bottleneck.

Similar Performance Alternatives

The CPU's nearest rivals in the benchmark database include the Intel Core i9-10900K, which scores 27872 on average, a 0.3% difference from the i5-12600KF's 27799. The AMD Ryzen 7 5800X3D scores 27896, also 0.3% higher, while the AMD Ryzen 7 6800U and AMD Ryzen 5 8500GE are within 0.3% as well. Any of these processors would deliver nearly identical frame rates in Doom when paired with the RTX 5080, as the game does not appear to be CPU-limited at the tested resolutions.

For the GPU, the nearest rivals include the AMD Radeon RX 9070 GRE, which has a 2.2% higher average score of 57367. The AMD Radeon 8060S scores 55757 (0.6% lower), the AMD Radeon RX 6750 GRE 12 GB scores 55698 (0.7% lower), and the AMD Radeon Pro W5700X scores 54828 (2.3% lower). In practical terms, the RX 9070 GRE would produce slightly higher frame rates in Doom, while the other three would be marginally slower. The differences are small enough that the gaming experience would be effectively identical.

The RTX 5080's percentile ranking of 87 among all GPUs places it well above the median, and its average benchmark score of 56083 confirms it is a high-end part. The CPU's percentile of 79 is slightly lower, but the pairing still works well because Doom's engine favors GPU throughput at the resolutions tested.

The Verdict

The data confirms that this PC can run Doom with exceptional performance at every resolution and preset combination tested. According to the verdictByResolution data, all four settings — Low, Medium, High, and Ultra — are playable at 3840x2160, 2560x1440, and 1920x1080. The playable threshold is 60 FPS, and the lowest average recorded is 91.8 FPS at 4K Ultra.

At 1920x1080, the system delivers 253.5 FPS on Ultra, which is more than four times the playable threshold. At 2560x1440, Ultra averages 167.9 FPS, still nearly three times the threshold. At 3840x2160, Ultra averages 91.8 FPS, which is 31.8 FPS above the playable threshold and comfortably within high-refresh-rate territory for most monitors.

The best settings per resolution are Ultra in every case, with the average FPS at those settings being 91.8 at 4K, 167.9 at 1440p, and 253.5 at 1080p. This means there is no need to compromise on graphical fidelity to achieve playable frame rates. The system has enough headroom to run the game at maximum settings on a 4K display while still maintaining an average above 90 FPS.

Best Settings per Resolution

For 3840x2160, Ultra settings provide an average of 91.8 FPS, which is the most demanding preset that stays at or above 60 FPS. The next lower preset, High, averages 112.9 FPS, but Ultra is the preferred choice given the substantial margin above the threshold.

At 2560x1440, Ultra averages 167.9 FPS, making it the clear best setting. The frame rate is high enough to support 144 Hz displays fully, and there is no benefit to dropping to High (206.1 FPS) unless the user prioritizes maximum frame rates over visual quality.

At 1920x1080, Ultra averages 253.5 FPS, which is well above any mainstream display refresh rate. The system can handle the most demanding preset with ease, and the 410.5 FPS Low preset is only relevant for competitive play where every frame matters.

How This Combo Ranks

The combination of the Intel Core i5-12600KF and NVIDIA GeForce RTX 5080 ranks 157 out of 3712 tested combos in Doom. This places it in the top 4.2% of all configurations, which is consistent with the high frame rates observed across all resolutions and presets. The rank reflects the GPU's strong showing — the RTX 5080 sits in the 87th percentile among all GPUs — combined with a CPU that is in the 79th percentile.

The ranking suggests that this system outperforms the vast majority of tested hardware in Doom, but it is not the absolute top configuration. The 157th position out of 3712 means there are 156 combinations that achieve higher performance in this specific game. Given that the RTX 5080's nearest GPU rival, the RX 9070 GRE, scores 2.2% higher on average, it is likely that some of the higher-ranked combos use that GPU or the next-tier NVIDIA parts.

The gap between this combo and the top-ranked configurations is unknown from the data, but the performance at 4K Ultra — 91.8 FPS — indicates that even the fastest systems would only be marginally better. For practical purposes, this is a high-end configuration that delivers playable frame rates at maximum settings on a 4K display, with substantial headroom for higher refresh rates at lower resolutions. The rank of 157 confirms that while there is faster hardware available, this pairing is firmly in the upper echelon of Doom performance.
