Doom

The Intel Core i5-14600KF and AMD Radeon RX 6750 XT combination delivers a solid, high-refresh-rate experience in Doom, ranking in the 49th percentile of tested combos (828 out of 1681). This is a pairing where the GPU is the primary bottleneck at higher resolutions, but the CPU's strength ensures that 1080p performance is exceptionally high, making it a versatile option for competitive and single-player play alike.

How This Combo Ranks

The combo's rank of 828 out of 1681 tested pairings places it just below the midpoint of all possible configurations. This position is not a reflection of weak components, but rather an indicator that Doom is a well-optimized title that runs exceptionally well on a wide range of hardware. The benchmark results show this combo is capable of delivering frame rates that far exceed the typical 60 FPS target at 1440p, which is where most of its competition likely falls behind.

Looking at the individual components, the CPU sits in the 93rd percentile of all processors, while the GPU is in the 79th percentile. This suggests the pairing is balanced, but the CPU has more headroom than the GPU in this specific title. The i5-14600KF's nearest rivals in synthetic benchmarks include the Intel Core i5-14600K, which is 0.4% slower, and the AMD Ryzen 9 5950X, which is 0.6% slower. This consistency in CPU performance means the primary differentiator in this game's frame rates will come down to the graphics card, and the RX 6750 XT is well-positioned for this task.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with a Navi 22 chip. Its 12 GB of GDDR6 memory on a 192-bit bus provides 432.0 GB/s of bandwidth, which is more than sufficient for Doom's textures and geometry at high settings. The GPU's boost clock of 2600 MHz and game clock of 2495 MHz are high for its class, allowing it to maintain strong throughput in a fast-paced FPS.

The GPU's performance in synthetic benchmarks, such as a 20700 score in Passmark G3D, shows it is a capable mid-range card. Its nearest rivals in terms of average benchmark score include the NVIDIA GeForce RTX 3080, which is only 1.3% faster, and the AMD Radeon RX 5600M, which is 0.2% slower. This indicates that the RX 6750 XT is performing at a level that is competitive with some higher-tier cards, even if its raw specifications are more modest. The data shows this card is the limiting factor in this combo, as the CPU can clearly push far beyond the frame rates the GPU can produce at lower resolutions.

Resolution Scaling

The FPS data shows a clear, predictable scaling pattern as resolution increases. At 1080p with High settings, the combo achieves 179.6 FPS. Moving to 1440p, that number drops to 117.4 FPS, a 34.6% decrease. At 4K, the frame rate falls to 59.9 FPS, which is a 49% drop from the 1440p result and a 66.6% drop from 1080p. This steep decline indicates that the RX 6750 XT is the dominant bottleneck at 4K, as the CPU's workload does not increase significantly with resolution.

At 1080p with Low settings, the combo hits 239.6 FPS, which is a massive frame rate that showcases the CPU's ability to feed the GPU. The difference between 1080p Low and 1080p High is 60 FPS, which shows that the GPU is still doing a significant amount of work. However, the fact that the 1080p Low result is nearly 240 FPS suggests that the CPU is capable of handling even more if the GPU were faster. The scaling from Low to Ultra at each resolution is consistent, with Ultra settings always costing the most performance.

Measured FPS Breakdown

At 1920x1080, the combo provides excellent performance across all settings. Low settings produce an average of 239.6 FPS, which is ideal for high-refresh-rate monitors. Medium settings reduce this to 211.9 FPS, a 11.6% drop. High settings are still very fast at 179.6 FPS, and even Ultra settings maintain a playable 144.1 FPS. This resolution is clearly CPU-bound, as the frame rates are extremely high and the differences between settings are relatively small in percentage terms.

At 2560x1440, the GPU starts to become a more significant factor. Low settings yield 155.5 FPS, which is still excellent. Medium settings deliver 134.6 FPS, and High settings drop to 117.4 FPS. Ultra settings produce 97.2 FPS, which is still well above the 60 FPS threshold for smooth gameplay. The performance gap between Low and Ultra at this resolution is 58.3 FPS, showing that the GPU is working harder.

At 3840x2160, the GPU is the clear limiting factor. Ultra settings produce an average of 48.5 FPS, which is below the ideal 60 FPS target. High settings are also not quite at 60 FPS, with an average of 59.9 FPS. Medium settings provide a playable 76.1 FPS, and Low settings are the only way to get a comfortable margin above 60 FPS, achieving 84.7 FPS. The data shows that 4K is only viable with reduced settings on this combo.

FAQ

Q: Is this combo capable of 1440p gaming at high refresh rates?

A: Yes. At 2560x1440 with High settings, the combo achieves an average of 117.4 FPS. Even on Ultra settings, it maintains 97.2 FPS, making it an excellent choice for 1440p 100Hz or 120Hz displays.

Q: Can this combo handle 4K gaming?

A: It is borderline. At 4K with High settings, the average FPS is 59.9, which is just at the edge of 60 FPS. To get a more comfortable frame rate, you would need to drop to Medium settings, which yield 76.1 FPS, or Low settings for 84.7 FPS.

Q: How does the CPU's performance compare to its nearest rivals?

A: The Intel Core i5-14600KF has an average benchmark score of 49367. Its closest rival, the Intel Core i5-14600K, scores 49166, which is 0.4% lower. The AMD Ryzen 9 5950X scores 49062, which is 0.6% lower.

Q: What is the GPU's performance percentile relative to all GPUs?

A: The AMD Radeon RX 6750 XT is in the 79th percentile of all GPUs, with an average benchmark score of 35327. This places it in the upper mid-range tier of graphics cards.

Q: What is the best resolution for this combo to maximize frame rate?

A: The data shows that at 1920x1080 with Low settings, the combo reaches 239.6 FPS. This is the highest measured frame rate. For a balance of quality and speed, 2560x1440 with High settings is a strong choice at 117.4 FPS.

Q: Is the CPU or GPU the bottleneck in Doom?

A: At 1080p, the CPU is clearly capable of more, as seen by the 239.6 FPS on Low settings. However, as resolution increases to 1440p and 4K, the GPU becomes the limiting factor, evidenced by the significant FPS drops when moving to Ultra settings.

Settings Recommendations

For the best overall experience, the 2560x1440 High preset is the sweet spot. It delivers 117.4 FPS, which is well above the 60 FPS standard and provides a significant visual upgrade over Low or Medium settings. The frame rate is high enough to take advantage of 100Hz monitors and provides a responsive feel for fast-paced action.

If you prefer maximum visual fidelity, 2560x1440 Ultra is still a viable option at 97.2 FPS. This setting offers the best image quality while staying comfortably above the 60 FPS threshold. For players with 4K displays, 3840x2160 Medium is the recommended preset, as it is the only way to achieve a smooth frame rate (76.1 FPS) without sacrificing too much visual quality. At 1080p, the Ultra preset at 144.1 FPS is the best choice, as it provides the highest fidelity while still maintaining a high refresh rate.

CPU Role

The Intel Core i5-14600KF is a 14-core, 20-thread processor based on the Raptor Lake architecture. Its boost clock of 5.30 GHz and 24 MB of shared L3 cache are key to its strong performance in Doom. The CPU's benchmark results, such as a 32889 score in Cinebench R23 multicore and a 4643 score in single-core, show it has immense processing power. In this game, the CPU's role is to feed the GPU with draw calls and game logic, and its high single-core performance is crucial for achieving the high frame rates seen at 1080p.

The data shows that the CPU is not the limiting factor in this combo. At 1080p Low, the frame rate of 239.6 FPS is likely near the game's engine limit, and the CPU is capable of even more. The CPU's percentile of 93 means it outperforms the vast majority of processors, and its nearest rivals are all within 1.4% of its average score. This means that in Doom, the i5-14600KF provides a stable and powerful foundation, leaving the RX 6750 XT as the component that determines the final frame rate at higher resolutions.
