Doom

The Intel Core i9-14900K paired with the AMD Radeon RX 5700 XT holds a combo rank of 1286 out of 1681 tested combinations in Doom. This places the pairing in the bottom quarter of all tested hardware configurations for this title, a surprisingly modest position given the CPU's exceptional standing in general benchmarks. The data suggests that this game's performance is heavily dictated by the graphics card, and the RX 5700 XT, while competent, cannot leverage the full potential of the flagship processor. The ranking implies that many less expensive CPU configurations paired with stronger GPUs would likely outperform this specific combination in Doom's high-refresh-rate environments.

GPU Role

The AMD Radeon RX 5700 XT is the primary performance bottleneck in this configuration. It features 8 GB of GDDR6 memory on a 256-bit bus, providing 448.0 GB/s of bandwidth, and is built on the RDNA 1.0 architecture using a 7 nm process. Its boost clock is rated at 1905 MHz, with a game clock of 1755 MHz. These specifications are typical for a mid-range card from its generation, and the benchmark results reflect that.

The GPU's percentile rating of 68 against all GPUs indicates it is outclassed by roughly a third of the available graphics cards on the market. In the context of Doom, a fast-paced FPS, this hardware's limits become apparent at higher settings. The data shows the GPU's raw compute capability is 9.754 TFLOPS, which is sufficient for the game but not for pushing maximum frame rates at demanding resolutions. The 8 GB VRAM is adequate for the game's textures, but the card's overall architecture is the limiting factor.

Resolution Scaling

The measured FPS data reveals a steep performance curve across resolutions, clearly demonstrating where the bottleneck lies. At 1080p with Low settings, the combo achieves 186.5 FPS. This drops to 121.4 FPS at 1440p and further to 68.1 FPS at 4K. This pattern indicates that as resolution increases, the workload on the GPU grows exponentially, and the RX 5700 XT's processing power is insufficient to maintain high frame rates.

The scaling from 1080p to 4K is particularly telling. At Ultra settings, the average FPS falls from 116 at 1080p to 73.3 at 1440p, and finally to 39.3 at 4K. This 66% reduction from 1080p to 4K suggests the GPU is hitting its computational limits. Conversely, the extremely high frame rates at 1080p Low (186.5 FPS) indicate that the Intel Core i9-14900K is not the limiting factor at lower resolutions, as it can easily feed frames to the GPU. The performance drop is almost entirely attributable to the GPU's fill rate and compute throughput.

Measured FPS Breakdown

The benchmark data provides a complete matrix of average FPS across three resolutions and four settings: Low, Medium, High, and Ultra.

At 1920x1080, the combo produces 186.5 FPS on Low, 162.9 FPS on Medium, 137.1 FPS on High, and 116 FPS on Ultra. This is a healthy spread, with a 70.5 FPS difference between the lowest and highest settings, showing that the CPU can push the GPU effectively and that even Ultra settings are playable.

At 2560x1440, the numbers drop to 121.4 FPS on Low, 104.9 FPS on Medium, 88.5 FPS on High, and 73.3 FPS on Ultra. The gaps between settings shrink slightly, indicating the GPU is becoming the primary constraint. The 1440p Ultra result of 73.3 FPS is still above the 60 FPS threshold, making it a viable option for smooth gameplay.

At 3840x2160, performance becomes more demanding. The card manages 68.1 FPS on Low, 58 FPS on Medium, 49.6 FPS on High, and 39.3 FPS on Ultra. At 4K, only the Low preset achieves a frame rate comfortably above 60 FPS. The Ultra preset's 39.3 FPS would feel sluggish in a fast-paced title like Doom, suggesting that 4K gaming is only practical with significant graphical compromises.

Settings Recommendations

Based on the measured rows, the optimal experience for this combo on a 1080p display is the High preset. It delivers 137.1 FPS, which is well above the threshold for smooth gameplay on high-refresh-rate monitors, while offering a significant visual upgrade over Medium (162.9 FPS) and Low (186.5 FPS). The jump from High to Ultra only costs 21.1 FPS, but the difference between 137 and 116 FPS is noticeable in competitive scenarios.

For 1440p users, the High preset at 88.5 FPS is the best balance of visual fidelity and performance. It remains above 60 FPS, ensuring a fluid experience. The Medium preset at 104.9 FPS is also acceptable if a higher frame rate is preferred, but High provides a better image quality per frame. The Ultra preset at 73.3 FPS is still playable but comes close to the lower bounds of what is recommended for a shooter.

At 4K resolution, the data suggests that the Low preset is the only setting that guarantees a consistently smooth experience, with 68.1 FPS. The Medium preset at 58 FPS is borderline, and it may be acceptable for single-player, but it does not meet the standards for fast-paced multiplayer. The High and Ultra presets at 49.6 and 39.3 FPS respectively are below the ideal playability threshold for this genre.

CPU Role

The Intel Core i9-14900K is a 24-core, 32-thread processor based on the Raptor Lake architecture, with a base clock of 3.20 GHz and a boost clock of 6.00 GHz. Its performance in general benchmarks is exceptional, ranking in the 97th percentile of all CPUs. It scores 49872 in Cinebench R23 multi-core and 7040 in single-core, demonstrating immense processing power.

However, in Doom, this CPU's role is largely supportive. The game's engine is not heavily threaded, and the frame rates are overwhelmingly determined by the GPU. The data shows that the CPU is not a bottleneck, as evidenced by the high frame rates at 1080p Low, which would require a very capable processor to achieve. The i9-14900K's 36 MB of shared L3 cache and high single-core performance ensure that it can process game logic and draw calls without limiting the GPU.

In benchmark comparisons, the i9-14900K is 0.7% ahead of the Intel Core i9-14900KF and 0.9% ahead of the Intel Core Ultra 7 265K in average score. It is 0.3% behind the AMD EPYC 7413. These differences are negligible in gaming, confirming that the GPU is the sole determinant of performance in this specific pairing.

FAQ

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

A: The data shows that 1920x1080 offers the most headroom, with even the Ultra preset hitting 116 FPS. At 2560x1440, the High preset achieves 88.5 FPS, which is also good. 3840x2160 is only playable at Low settings (68.1 FPS).

Q: How does this combo rank against other tested configurations?

A: It ranks 1286 out of 1681 tested combos for Doom, placing it in the lower 25% of all pairings. This is largely due to the GPU's limitations relative to the CPU's capability.

Q: Is the Intel Core i9-14900K holding back the AMD Radeon RX 5700 XT?
