Doom

How This Combo Ranks

The Intel Core i9-14900K paired with the NVIDIA GeForce RTX 3080 lands at rank 512 out of 1681 tested combos in Doom. That places this setup in the upper third of all combinations, a strong result for a game that rewards high frame rates. The ranking reflects a system that is clearly capable of delivering smooth, fast-paced FPS gameplay without being at the absolute top of the charts.

Benchmark results indicate this combo sits comfortably above the median, with roughly two-thirds of tested configurations trailing behind it. The ranking is influenced by both components working in tandem, but the data suggests the RTX 3080 is the primary driver of this position. The i9-14900K is a top-tier processor, and its general benchmark percentile of 97 versus all CPUs confirms it is among the fastest available. However, in Doom, the GPU's performance ceiling becomes the limiting factor at higher resolutions and settings, which we will explore in the following sections.

GPU Role

The NVIDIA GeForce RTX 3080 is the workhorse of this combination for Doom. It is built on the Ampere architecture with a GA102 chip, manufactured on Samsung's 8 nm process. The card features 10 GB of GDDR6X memory on a 320-bit bus, providing a bandwidth of 760.3 GB/s. This memory configuration is substantial and directly contributes to the card's ability to handle the texture-heavy environments of Doom at high resolutions.

Clock speeds are set at a base of 1440 MHz with a boost up to 1710 MHz. The memory operates at 1188 MHz, translating to 19 Gbps effective. These numbers, combined with 8704 shading units, 272 texture mapping units, and 96 raster operation units, give the RTX 3080 a raw compute capability of 29.77 TFLOPS for FP32 operations. In practice, this translates to the measured FPS figures seen in the data. The GPU's percentile rank of 80 versus all GPUs indicates it outperforms the vast majority of graphics cards, though it is not at the very top tier.

The data shows that the RTX 3080 is the component that scales most directly with settings changes in Doom. When comparing the measured FPS across different quality presets, the GPU's workload increases predictably with higher settings. This is typical behavior for a game like Doom, which is well-optimized and can push high frame rates, making the GPU the primary bottleneck at 1440p and 4K resolutions.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance scaling across resolutions. At 1080p, the combo is exceptionally fast, with average frame rates well above 180 FPS on all settings. Moving to 1440p, there is a significant drop in performance, and at 4K, the frame rates fall further. This scaling tells us about the balance between CPU and GPU load.

At 1080p, the CPU has more headroom, and the RTX 3080 is able to push very high frame rates. The difference between Low and Ultra settings at 1080p is 119.5 FPS (302.6 vs 183.1), showing that the GPU is still the main variable even at this resolution. However, the CPU is not fully saturated, as the i9-14900K's 24 cores and 32 threads are more than enough for Doom's engine at this resolution.

At 4K, the frame rates drop to between 64.8 and 104.9 FPS, depending on settings. This is a substantial reduction and indicates that the GPU is now the clear limiting factor. The CPU's role diminishes as resolution increases, and the RTX 3080's 10 GB of VRAM and memory bandwidth become the determining factors. The data shows that the frame rate drop from 1080p to 4K is roughly 60% on Low settings (302.6 to 104.9), which is a typical pattern for a GPU-bound scenario at higher resolutions.

Measured FPS Breakdown

The measured FPS data provides a detailed look at performance across three resolutions and four quality settings. Here is the exact breakdown:

1920x1080 (1080p):

• Low: 302.6 FPS
• Medium: 260.8 FPS
• High: 221.2 FPS
• Ultra: 183.1 FPS

2560x1440 (1440p):

• Low: 194.5 FPS
• Medium: 169.2 FPS
• High: 142.4 FPS
• Ultra: 118.0 FPS

3840x2160 (4K):

• Low: 104.9 FPS
• Medium: 93.5 FPS
• High: 80.2 FPS
• Ultra: 64.8 FPS

At 1080p, the combo delivers exceptionally high frame rates, with even Ultra settings clearing 180 FPS. This is ideal for high-refresh-rate monitors. The gap between Low and Ultra is 119.5 FPS, showing the GPU's sensitivity to settings at this resolution.

At 1440p, performance remains very strong, with all settings above 118 FPS. The Ultra setting at 118 FPS is still smooth for most displays, while Low at 194.5 FPS is excellent for competitive play. The scaling from 1080p to 1440p shows a reduction of about 35% on average across settings.

At 4K, the combo is still playable, with the lowest setting at 104.9 FPS and Ultra at 64.8 FPS. While Ultra at 4K is just below the 70 FPS threshold many players prefer, the High setting at 80.2 FPS offers a good balance. This data confirms that the RTX 3080 is capable of 4K gaming in Doom, but users may need to adjust settings to maintain high frame rates.

FAQ

Q: What is the best resolution to use with this combo for the highest frame rates?

A: At 1080p, the combo delivers the highest frame rates, with Low settings hitting 302.6 FPS and Ultra still at 183.1 FPS. This resolution is best for competitive play or very high refresh rate monitors.

Q: Can this system handle 4K gaming in Doom?

A: Yes, the data shows playable performance at 4K. Even at Ultra settings, the average FPS is 64.8, while High settings give 80.2 FPS and Low gives 104.9 FPS. It is a capable 4K setup, though not at the highest refresh rates.

Q: How does the Ultra setting compare to High at 1440p?

A: At 1440p, Ultra averages 118.0 FPS, while High averages 142.4 FPS. The difference is 24.4 FPS, indicating that Ultra has a measurable performance cost at this resolution.

Q: Which component is the bottleneck for this combo in Doom?

A: The data shows the GPU is the primary bottleneck, especially at 1440p and 4K. At 1080p, the CPU has more headroom, but the frame rate differences between settings still point to the GPU as the main variable.

Q: Is the 10 GB VRAM of the RTX 3080 sufficient for Doom at 4K?

A: The measured results indicate that 10 GB of GDDR6X memory is sufficient for Doom at 4K, as the game runs at playable frame rates across all settings. The 760.3 GB/s bandwidth supports the texture loads without significant issues.

Q: How does this combo rank among all tested configurations?

A: It ranks 512 out of 1681 tested combos, placing it in the upper third of all systems tested for Doom. This is a strong position for a high-performance gaming setup.

CPU Role

The Intel Core i9-14900K plays a supporting but important role in this combo. It is a 24-core, 32-thread processor based on the Raptor Lake architecture, manufactured on Intel's 10 nm process. Its base clock is 3.20 GHz, with a boost clock of 6.00 GHz. The CPU has 36 MB of shared L3 cache, with 2 MB of L2 cache per core and 80 KB of L1 cache per core.

In Doom, the CPU's role is to feed the GPU with data quickly and efficiently. The i9-14900K excels at this, with its high boost clock and many cores ensuring that the GPU is never starved of data. Benchmark results show a Cinebench R23 multi-core score of 49872 and a single-core score of 7040, indicating exceptional processing power. Its general benchmark percentile of 97 versus all CPUs puts it ahead of most other processors.

However, the data in this game suggests that the CPU is not the limiting factor. At 1080p, where CPU load is highest relative to GPU load, the combo still delivers over 300 FPS on Low settings. This indicates that the i9-14900K has ample headroom. At 4K, the GPU becomes the clear bottleneck, and the CPU's performance has less impact on the final frame rate. The CPU's role is to ensure consistent frame pacing and avoid dips, which its strong single-thread performance supports. The nearest rivals in overall CPU benchmarks include the AMD EPYC 7413, which is 0.3% faster, and the Intel Core i9-14900KF, which is 0.7% slower, showing this chip is at the top of its class.
