Doom

The Intel Core i5-12600KF paired with the NVIDIA GeForce RTX 3080 delivers a performance profile in Doom that is heavily dictated by resolution and graphics settings. The dataset shows a clear hierarchy where the GPU becomes the primary bottleneck at higher resolutions, while the CPU's capabilities are sufficient to avoid limiting frame rates at lower settings. This analysis breaks down the measured FPS data, the role of each component, and how this specific combination ranks against other tested hardware.

Resolution Scaling

The frame rate scaling from 1920x1080 to 3840x2160 reveals a predictable but steep decline in performance as pixel count increases. At the High preset, the average FPS drops from 221 at 1080p to 143 at 1440p, representing a 35% reduction. The jump to 4K is more punishing, with the average falling to 78 FPS, a 45% drop from the 1440p figure. This pattern indicates that the workload scales almost linearly with the number of pixels, which is characteristic of a GPU-bound scenario at higher resolutions.

The scaling is even more pronounced when comparing the Low preset across all three resolutions. At 1080p Low, the combination achieves 301 FPS, which is an exceptionally high frame rate. At 1440p Low, this falls to 195 FPS, and at 4K Low, it drops to 105 FPS. The progression from 1080p to 4K at Low settings results in a 65% reduction in average FPS. This steep curve suggests that while the RTX 3080 is capable of extremely high frame rates at lower resolutions, the sheer pixel count of 4K begins to saturate its rendering pipeline.

The gap between the Low and Ultra presets widens as resolution increases. At 1080p, the difference between Low (301 FPS) and Ultra (181 FPS) is 120 FPS. At 1440p, the gap narrows to 78 FPS (195 Low vs 117 Ultra). At 4K, the difference is 42 FPS (105 Low vs 63 Ultra). This narrowing delta indicates that at lower resolutions, there is ample headroom for the GPU to handle increased graphical fidelity, but at 4K Ultra, the GPU is working near its limit, leaving less room for settings-based performance variation.

The data strongly suggests that the RTX 3080 is the limiting component at 4K, particularly at higher settings. At 4K Ultra, the average FPS of 63 is the lowest recorded in the entire dataset, and it falls just below the 78 FPS minimum observed at 4K Medium. This indicates that the GPU is fully utilized at this configuration, and any additional graphical load would likely result in sub-60 FPS performance. Conversely, at 1080p, the system appears to be more balanced, with the CPU potentially playing a larger role in determining the final frame rate.

CPU Role

The Intel Core i5-12600KF features 10 cores and 16 threads, with a base clock of 3.70 GHz and a boost clock of 4.90 GHz. Its benchmark scores show strong single-threaded performance, with a 3dmark_single_thread score of 1016 and a passmark_single_thread score of 3925. In the context of Doom, which is a fast-paced FPS that typically benefits from high single-core performance, these numbers suggest the CPU is well-suited to handle the game's logic and physics calculations without becoming a bottleneck.

The CPU's multi-threaded capabilities are also robust, as evidenced by a cinebench_r23_multicore score of 23391 and a 3dmark_max_threads score of 7952. However, the data indicates that these extra threads are not heavily utilized in this game, as the frame rate scaling with resolution follows a GPU-bound pattern. At 1080p Low, the system achieves 301 FPS, which is likely near the upper limit of what the game engine can render. If the CPU were the limiting factor, we would expect to see similar frame rates regardless of resolution, but the significant drops at 1440p and 4K confirm that the GPU is the primary constraint.

The CPU's performance relative to other processors is solid, with a percentileVsAllCpus of 79. Its nearest rivals include the Intel Core i9-10900K, which scores slightly higher (deltaPct of -0.3), and the AMD Ryzen 7 5800X3D, which also edges it out by a small margin (-0.3). These deltas are minimal, suggesting that the i5-12600KF is competitive with higher-tier CPUs from previous generations, and it is unlikely to cause any meaningful frame rate differences in Doom when paired with a capable GPU.

Given the high frame rates observed at 1080p, the CPU appears to have sufficient headroom to feed the RTX 3080. The fact that 1080p Low reaches 301 FPS, which is a very high refresh rate target, indicates that the processor can sustain the necessary draw calls and game state updates without introducing a significant bottleneck. At 4K, the CPU's role diminishes further, as the GPU's rendering time dominates the frame time budget.

The measured FPS data shows that at 4K, the average frame rates range from 63 (Ultra) to 105 (Low), with the GPU being the primary driver of these differences. The 10 GB of VRAM is likely sufficient for this game, as even at 4K Ultra, the system maintains a stable 63 FPS average without any indication of memory-related stuttering or frame drops.

The GPU's clock speeds and memory bandwidth are also relevant. The 760.3 GB/s bandwidth ensures that texture data can be loaded quickly, which is important for a fast-paced FPS with detailed environments. The boost clock of 1710 MHz allows the GPU to reach high performance levels under load, as evidenced by the 301 FPS at 1080p Low. Overall, the RTX 3080 is the primary factor in this combo's performance, and its capabilities are fully utilized as resolution increases.

Measured FPS Breakdown

The dataset provides measured average FPS for four settings (Low, Medium, High, Ultra) across three resolutions (1920x1080, 2560x1440, 3840x2160). At 1080p, the average FPS ranges from 181 (Ultra) to 301 (Low). The Medium setting averages 262 FPS, with a minimum of 223 and a maximum of 301, while the High setting averages 221 FPS. These numbers indicate that the system can easily exceed 180 FPS at any setting at 1080p, making it ideal for high-refresh-rate monitors.

At 1440p, the average FPS drops to a range of 117 (Ultra) to 195 (Low). The Medium setting averages 170 FPS, with a minimum of 144 and a maximum of 195. The High setting averages 143 FPS. These figures show that 1440p is still very playable, with even the Ultra preset maintaining an average above 115 FPS. The minimum FPS of 144 at Medium settings indicates that the system rarely drops below the refresh rate of a standard 144 Hz monitor.

At 4K, the average FPS ranges from 63 (Ultra) to 105 (Low). The Medium setting averages 92 FPS, with a minimum of 78 and a maximum of 106. The High setting averages 78 FPS. This data reveals that 4K gaming is possible with this combo, but users may need to compromise on settings to achieve higher frame rates. The Low preset at 105 FPS is the most playable at 4K, while the Ultra preset at 63 FPS is borderline for smooth gameplay.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. For users with a 1080p monitor, the Ultra preset at 181 FPS is recommended, as it provides the highest visual quality while still delivering frame rates well above 144 Hz. If a user prioritizes maximum frame rates for competitive play, the Low preset at 301 FPS is the best choice, but the visual trade-off may not be worth it for most players.

At 1440p, the Medium preset offers the best balance between visual fidelity and performance, with an average of 170 FPS and a minimum of 144 FPS. This ensures that the frame rate rarely drops below the refresh rate of a standard 144 Hz display. The High preset at 143 FPS is also acceptable, but it sits right at the edge of 144 Hz, so users with a 144 Hz monitor may prefer the Medium setting for a more consistent experience.

For 4K gaming, the Low preset at 105 FPS is the most playable option, but it sacrifices significant visual quality. The Medium preset at 92 FPS is a reasonable middle ground, offering a 92 FPS average with a minimum of 78 FPS. The High preset at 78 FPS is playable but may show occasional dips below 60 FPS in demanding scenes. The Ultra preset at 63 FPS is not recommended for 4K, as it approaches the lower bound of acceptable frame rates and leaves little headroom for demanding scenes.

In summary, the data suggests that the best experience for this combo is at 1440p with Medium settings, which provides a high average FPS and a minimum that stays above 144 FPS. For 1080p users, Ultra settings are the best choice. For 4K users, Medium settings offer the best trade-off between visual quality and smoothness, while those seeking higher frame rates should opt for Low settings.
