Doom

The benchmark data for Doom on this Intel Core i7-14700KF and AMD Radeon RX 7900 XTX combination reveals a system with immense headroom at standard resolutions, but the performance profile shifts dramatically as the workload scales. The measured FPS across all settings and resolutions paints a clear picture of a GPU-bound system at 4K, transitioning to a more balanced load at 1440p and 1080p. This analysis breaks down the measured rows to determine the optimal experience, the role of each component, and how this specific pairing ranks against other tested configurations.

Settings Recommendations

The measured data indicates that the High preset at 2560x1440 provides the most balanced experience, delivering an average of 175.3 FPS. This is a substantial jump from the 145 FPS at Ultra, representing a 20.9% performance increase while likely offering a visually indistinguishable difference in a fast-paced title like Doom. The jump from High to Ultra at 1440p costs 30.3 FPS, a significant 17.3% drop, making High the optimal ceiling for this resolution.

At 3840x2160, the Medium preset is the most sensible choice, with an average of 108.9 FPS. This is a healthy 46.4% improvement over the 74.4 FPS seen at Ultra, which is critical for maintaining smooth gameplay. While High at 4K offers 97.1 FPS, the 11.8 FPS difference between Medium and High is less impactful than the 34.5 FPS gap between High and Ultra. The data suggests that the Ultra preset is not viable at 4K, as the 74.4 FPS average may dip below the threshold for high-refresh-rate monitors.

For 1920x1080, the High preset at 269.4 FPS is the recommended setting. While Low produces 365.1 FPS and Medium produces 318.1 FPS, these settings likely reduce visual fidelity for marginal gains in frame rate that exceed most display refresh rates. The Ultra preset at 218.1 FPS is still excellent but the 19% penalty over High is not justified when the High preset already provides a massive frame rate advantage. The data shows that High at 1080p is the sweet spot, balancing a high average FPS with the visual quality expected from this hardware tier.

GPU Role

The AMD Radeon RX 7900 XTX is the dominant component in this configuration for this game. Its 24 GB of GDDR6 memory on a 384-bit bus provides 960.0 GB/s of bandwidth, which is more than sufficient for Doom's textures and geometry at any of the tested settings. The GPU's 6144 shading units, 384 TMUs, and 192 ROPs are the primary drivers of the frame rate differences observed between resolution and quality presets.

The clock speeds are also a critical factor. The GPU's boost clock of 2498 MHz and game clock of 2365 MHz are high for the RDNA 3.0 architecture, allowing the card to maintain strong throughput. This is evident in the 4K results, where the GPU is clearly the limiting factor. The drop from 126.1 FPS at Low to 74.4 FPS at Ultra at 3840x2160 is a 40.9% reduction, which is almost entirely due to the increased pixel shading and texture work being handled by the RX 7900 XTX. Its FP32 performance of 61.39 TFLOPS is a strong indicator of its ability to handle the compute load, but the data shows that even this powerful GPU struggles to maintain high frame rates at the most demanding 4K preset.

Resolution Scaling

The FPS scaling from 1080p to 4K demonstrates a classic GPU-bound scenario. At the High preset, the average frame rate drops from 269.4 FPS at 1920x1080 to 175.3 FPS at 2560x1440 and then to 97.1 FPS at 3840x2160. This represents a 64.0% reduction in FPS from 1080p to 4K. The scaling is not linear, with the jump from 1440p to 4K being more punishing (a 44.6% drop) than the jump from 1080p to 1440p (a 34.9% drop).

This pattern strongly suggests that the CPU is not a bottleneck at 1080p, where the GPU is still able to push out very high frame rates. However, as resolution increases, the pixel fill rate demands on the GPU grow exponentially, and the RX 7900 XTX begins to hit its limits. The fact that the 1080p Low setting (365.1 FPS) is only 18.5% faster than the 1080p High setting (269.4 FPS) further indicates that the CPU is starting to become a factor at these extreme frame rates, but the GPU is still the primary constraint. The data implies that the CPU has enough headroom to feed the GPU at 1440p and 4K, but at 1080p with lower settings, the system is approaching the point where the CPU's processing power could limit the maximum achievable frame rate.

Measured FPS Breakdown

The complete dataset shows a clear hierarchy of performance. At 1920x1080, the average FPS ranges from 365.1 at Low to 218.1 at Ultra. The progression from Low to Medium (318.1 FPS) to High (269.4 FPS) shows a consistent step-down in performance as visual quality increases. The gap between Medium and High is 48.7 FPS, while the gap between High and Ultra is 51.3 FPS, showing a near-linear penalty for each quality tier.

At 2560x1440, the average FPS ranges from 235.5 at Low to 145.0 at Ultra. The scaling is similar to 1080p, with a 27.5 FPS drop from Low to Medium (208 FPS), a 32.7 FPS drop from Medium to High (175.3 FPS), and a 30.3 FPS drop from High to Ultra. The consistency of these deltas suggests a well-balanced scaling curve, with each preset costing a predictable amount of GPU throughput.

At 3840x2160, the average FPS ranges from 126.1 at Low to 74.4 at Ultra. Here, the deltas are more compressed: a 17.2 FPS drop from Low to Medium (108.9 FPS), an 11.8 FPS drop from Medium to High (97.1 FPS), and a 22.7 FPS drop from High to Ultra. The smaller absolute differences at 4K indicate that the GPU is working near its limits, and the relative cost of each setting is higher. The Ultra preset at 4K is the only configuration measured that falls below the 100 FPS mark, highlighting the extreme demands of this combination.

How This Combo Ranks

This specific combination of the Intel Core i7-14700KF and AMD Radeon RX 7900 XTX has a combo rank of 235 out of 1681 tested combinations for Doom. This places it in the top 14.0% of all tested combos, which is a strong showing for a high-end desktop pairing. The rank reflects the system's ability to deliver high frame rates across the board, but it also indicates that there are other configurations that can achieve even higher performance in this title.

The CPU's individual performance is a contributing factor. Its average benchmark score of 70104 places it in the 96th percentile of all CPUs, with its nearest rival being the Intel Core i7-14700K at a 0% deltaPct. This means the 14700KF is essentially tied with its non-F counterpart, and it is only 0.3% ahead of the AMD EPYC 9115 and 0.4% behind the AMD Ryzen 9 9950X. For gaming, this CPU is more than capable of avoiding a bottleneck in most scenarios, but the rank of 235 out of 1681 suggests that the GPU is the primary determinant of the final FPS, and other GPU combinations may yield higher scores.

FAQ

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor based on the Raptor Lake architecture. Its base clock of 3.40 GHz and boost clock of 5.60 GHz provide strong single-threaded performance, which is crucial for game logic and frame pacing. The 33 MB of shared L3 cache helps reduce memory latency, ensuring the GPU is kept fed with data.

In this specific game, the CPU’s role is to ensure the GPU is never starved. The benchmark data shows that at 1080p, the frame rates are exceptionally high, hitting 365.1 FPS at Low settings. This indicates the CPU is capable of handling the game’s processing demands. However, the data also shows a diminishing return on FPS when lowering settings at 1080p. The jump from High to Low yields a 95.7 FPS increase, but the jump from High to Medium yields a more modest 48.7 FPS increase. This suggests that the CPU is starting to become a secondary bottleneck at these extreme frame rates, limiting the total output even when the GPU has more headroom. The CPU’s 96th percentile ranking and its close margin to the i7-14700K (0% deltaPct) confirm that it is a top-tier gaming processor, but even this powerful chip has limits when paired with a GPU like the RX 7900 XTX at lower resolutions.
