Doom

The pairing of Intel’s Core i5-14600KF with NVIDIA’s GeForce GTX 1070 creates a striking imbalance in Doom. The data shows a modern, high-core-count processor driving a legacy graphics card through a classic FPS title, yielding results that are entirely dictated by the GPU’s limits. This analysis breaks down the measured frames per second (FPS) across resolutions and settings, interpreting what the numbers reveal about the system’s behavior.

Resolution Scaling

The measured FPS data shows a predictable but steep decline as resolution increases, confirming the GTX 1070 as the primary bottleneck. At 1080p with High settings, the combo delivers 118.8 FPS. Moving to 1440p drops this to 77.7 FPS, a reduction of 41.1 FPS. The jump to 4K (3840x2160) further reduces the average to 43.8 FPS, which is a 75 FPS drop from the 1080p baseline. This trend is consistent across all settings presets, indicating that the GPU’s pixel-pushing capability is the limiting factor, not the CPU.

The scaling pattern suggests that the Core i5-14600KF is never the constraint in this game. The CPU’s performance headroom is vast, given its 14 cores and 20 threads, but the GTX 1070’s 8 GB of GDDR5 memory and 256-bit bus are saturated early. The FPS drop from 1080p to 1440p is roughly 35%, while the drop from 1440p to 4K is even more severe, around 44%. This non-linear scaling is typical of a GPU that runs out of memory bandwidth or shading power as pixel count increases. The data implies that players seeking higher resolutions would need a more modern graphics card, as the current setup is firmly GPU-bound.

CPU Role

The Intel Core i5-14600KF’s specifications are impressive on paper, but in Doom, they are largely underutilized. The chip features 14 cores, 20 threads, a base clock of 3.50 GHz, and a boost clock of 5.30 GHz. Its benchmark scores are equally strong, with a Cinebench R23 multi-core score of 32889 and a single-core score of 4643. However, the measured FPS data does not show any signs of CPU limitation, as the frame rates scale inversely with resolution, which is a classic GPU-bound scenario.

The CPU’s role here is to feed frames fast enough, which it does with ease. The data shows that at 1080p Low settings, the combo reaches 157.3 FPS, which is a high frame rate that still does not stress the CPU’s capabilities. The Core i5-14600KF’s nearest rivals, such as the Intel Core i5-14600K with a deltaPct of 0.4, show that its processing power is comparable to top-tier desktop chips. Yet, in this game, the CPU’s potential is wasted because the GTX 1070 cannot keep up. The conclusion is that the CPU is not the limiting component; it is the GPU that dictates the performance ceiling.

Settings Recommendations

The measured rows provide a clear picture of how settings affect performance. At 1080p, the Ultra preset yields 98 FPS, which is playable, but the High preset offers a significant jump to 118.8 FPS. The Medium preset reaches 136 FPS, and Low peaks at 157.3 FPS. For a balanced experience, the data suggests that High settings at 1080p are the sweet spot, offering a substantial visual upgrade over Low while maintaining a frame rate above 100 FPS.

At 1440p, the situation changes. High settings produce 77.7 FPS, which is still smooth, but Ultra drops to 62.6 FPS. The Medium preset at 88.4 FPS appears to be the best compromise for 1440p, providing a higher frame rate than High while sacrificing some visual fidelity. At 4K, the data shows that even Low settings only reach 53.9 FPS, which is below the 60 FPS threshold for most players. Therefore, the recommendation is to stick to 1080p or 1440p, with High or Medium settings respectively, as the 4K experience is compromised across the board.

FAQ

Q: What is the best resolution to play Doom with this combo?

A: The data shows that 1080p provides the highest frame rates, with the Low preset reaching 157.3 FPS and High reaching 118.8 FPS. 1440p is also viable, with Medium at 88.4 FPS, but 4K struggles, with even Low settings only hitting 53.9 FPS.

Q: How does the Core i5-14600KF compare to its nearest rivals?

A: The Core i5-14600KF has an average benchmark score of 49367, which is 0.4% higher than the Intel Core i5-14600K, 0.6% higher than the AMD Ryzen 9 5950X, and 1.4% higher than the Intel Xeon Gold 5318H. It is 0.5% lower than the AMD EPYC 4345P.

Q: Is the GTX 1070 a bottleneck at 1080p?

A: Yes, the data indicates a GPU bottleneck. At 1080p, the frame rates vary significantly with settings, from 98 FPS at Ultra to 157.3 FPS at Low. This variation is a sign that the GPU is the limiting factor, as a CPU bottleneck would show less variation across settings.

Q: What is the difference in FPS between Ultra and Low settings at 1440p?

A: At 1440p, the Ultra preset averages 62.6 FPS, while the Low preset averages 99.4 FPS. This is a difference of 36.8 FPS, showing that the GTX 1070’s performance is heavily impacted by graphical load.

Q: How does the GTX 1070’s benchmark score compare to its rivals?

A: The GTX 1070 has an average benchmark score of 12331, which is 0.7% higher than the NVIDIA Quadro K4200, but 1.3% lower than the NVIDIA GeForce GTX 880M and 1.4% lower than the NVIDIA GeForce GTX 1650 SUPER.

Q: Can this combo handle 4K gaming?

A: The data shows it is not recommended. At 4K, the highest average FPS is 53.9 at Low settings, and the Ultra preset drops to 31.4 FPS. These numbers are below the standard for smooth gameplay.

GPU Role

The NVIDIA GeForce GTX 1070 is the definitive limiting factor in this configuration. Its specifications are dated but still relevant: 1920 shading units, 64 ROPs, a base clock of 1506 MHz, and a boost clock of 1683 MHz. The 8 GB of GDDR5 memory on a 256-bit bus provides 256.3 GB/s of bandwidth. In Doom, these specs translate to a performance envelope that is quickly exceeded by higher resolutions and settings.

The GPU’s benchmark scores reflect its mid-range position. It achieves a Passmark G3D score of 13498 and a 3DMark Steel Nomad DX12 score of 1082. Its percentile ranking is 51, meaning it sits in the middle of all GPUs. The data shows that the GPU’s performance drops sharply as the pixel count increases. At 1080p, it can push over 150 FPS on Low settings, but at 4K, it struggles to maintain 50 FPS. This is a classic sign of a GPU that lacks the raw compute power and memory bandwidth for high-resolution gaming. The GTX 1070’s role is to provide a baseline experience, but it cannot keep pace with the CPU’s potential.

Measured FPS Breakdown

The measured FPS data provides a detailed look at performance across all combinations. At 1920x1080, the average FPS ranges from 98 at Ultra to 157.3 at Low. The Medium preset hits 136 FPS, and High lands at 118.8. At 2560x1440, the numbers drop: Low is 99.4, Medium is 88.4, High is 77.7, and Ultra is 62.6. At 3840x2160, the performance is severely limited: Low is 53.9, Medium is 46.1, High is 43.8, and Ultra is 31.4.

These numbers tell a clear story. The delta between Low and Ultra at 1080p is 59.3 FPS, which is a massive gap. At 1440p, the gap narrows to 36.8 FPS, and at 4K, it shrinks to 22.5 FPS. This narrowing indicates that the GPU is becoming the sole bottleneck at higher resolutions, as the settings have less relative impact. The data also shows that the difference between Medium and High is smaller than between Low and Medium, suggesting that the GTX 1070 has a performance cliff that is crossed when moving to higher-quality presets.

How This Combo Ranks

In the grand scheme of tested combinations, this pairing ranks low. The comboRankInGame is 1412 out of 1681 combos, placing it in the bottom 16% of all systems tested. This ranking is unsurprising given the age and performance level of the GTX 1070. The data implies that while the CPU is a top-tier performer, the GPU drags the overall system down significantly.

This rank is a direct consequence of the GPU’s limitations. The Core i5-14600KF is ranked in the 93rd percentile of all CPUs, but the GTX 1070 is only in the 51st percentile of GPUs. The combination of a high-end CPU with a mid-range GPU results in a system that is severely unbalanced for modern gaming. The data suggests that a more balanced pairing, such as the GTX 1070 with a less powerful CPU, would yield a similar gaming experience, as the GPU is the limiting factor. This ranking serves as a cautionary tale about the importance of GPU selection in gaming builds, regardless of CPU strength.
