Doom

The Intel Core i7-14700KF paired with the AMD Radeon RX 6700 XT delivers a performance curve in Doom that clearly illustrates where the graphical bottleneck begins to bite. At 1920x1080 with High settings, the combo produces 169 FPS average, but that figure climbs steeply as settings are lowered, reaching 230 FPS at Low and 200 FPS at Medium. This indicates that at 1080p, the system has substantial headroom, and the GPU is not yet the limiting factor at higher quality presets. Moving to 2560x1440, the average FPS at High drops to 110, which is a 35% reduction from the 1080p High result, showing the expected scaling penalty as pixel count increases. The pattern continues at 3840x2160, where High settings yield just 59 FPS average, a 46% drop from the 1440p High figure and a 65% drop from 1080p High. The data shows that from 1080p to 4K at High settings, the frame rate falls by 110 FPS, which strongly suggests that the RX 6700 XT's rendering throughput is the primary constraint at higher resolutions.

The resolution scaling becomes even more telling when examining the Low preset across all three resolutions. At 1080p Low, the combo hits 230 FPS, which drops to 149 FPS at 1440p and 81 FPS at 4K. The gap between 1080p Low and 1440p Low is 81 FPS, while the gap between 1440p Low and 4K Low is 68 FPS, indicating a relatively consistent degradation per pixel-count increase. However, the difference between High and Low at 4K is 22 FPS (59 vs 81), while at 1080p that same difference is 61 FPS (169 vs 230). This narrowing delta at 4K confirms that the GPU is becoming saturated, as lowering settings provides diminishing returns when the fill-rate and shading demands of 4K overwhelm the card. The Ultra preset tells a similar story: 138 FPS at 1080p, 90 FPS at 1440p, and 49 FPS at 4K. The 4K Ultra result is the only sub-60 FPS figure in the entire dataset, reinforcing that this resolution and preset combination pushes the hardware past its comfortable operating range.

GPU Role

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture with a 7 nm process from TSMC, featuring a chip with 17,200 million transistors on a 335 mm² die. Its clock behavior is notable: a base clock of 2321 MHz, a game clock of 2424 MHz, and a boost clock of 2581 MHz, with memory running at 2000 MHz or 16 Gbps effective. The card carries 12 GB of GDDR6 memory on a 192-bit bus, yielding a bandwidth of 384.0 GB/s. These specifications position the GPU to handle Doom's demands, but the measured FPS data reveals that the memory subsystem and compute units are taxed heavily at 4K. The card's FP32 performance is 13.21 TFLOPS, and its texture rate is 413.0 GTexel/s, with a pixel rate of 165.2 GPixel/s, figures that explain why 1080p and 1440p performance is robust while 4K Ultra stumbles to 49 FPS average.

The benchmark results for this GPU show a PassMark G3D score of 19786 and a 3DMark Steel Nomad DX12 score of 2435, placing it in the 72nd percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce RTX 3090, which scores 27565 (a 0.5% delta), and the NVIDIA GeForce RTX 4070 Mobile at 27435 (a 0% delta). The RX 6700 XT's average benchmark score of 27425 puts it just below the RTX 4070 Mobile, yet in Doom specifically, the measured FPS at 4K High (59 FPS) suggests that the card's 12 GB VRAM capacity is sufficient for this title, as no texture thrashing or memory-related stutter is evident in the min FPS data (60 FPS at 4K Medium). The GPU's DirectX 12 Ultimate support (12_2) and Vulkan 1.4 API compatibility align well with Doom's engine, which leverages modern graphics APIs efficiently. The card's TDP of 230 W and suggested PSU of 550 W are not directly reflected in the FPS numbers, but the sustained 59 FPS at 4K High indicates the GPU is operating within its thermal and power envelope without throttling-induced dips.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for this combo depend heavily on the target resolution and desired frame rate floor. At 1920x1080, every preset delivers playable performance, with Ultra averaging 138 FPS, High at 169 FPS, Medium at 200 FPS, and Low at 230 FPS. For a smooth high-refresh experience at 1080p, High settings strike the best balance, offering 169 FPS average which is 31 FPS above the Ultra preset and still 61 FPS below the Low ceiling, but with substantially better visual quality. At 2560x1440, the High preset produces 110 FPS average, which is perfectly smooth for most displays, while Ultra drops to 90 FPS and Medium climbs to 130 FPS. The data shows that Medium at 1440p provides a 20 FPS advantage over High (130 vs 110), but High's visual fidelity may be worth the trade-off for users with 144 Hz monitors. At 3840x2160, the choices become more constrained: High averages 59 FPS, which is just below the 60 FPS threshold, while Medium averages 70 FPS with a minimum of 60 FPS, and Low averages 81 FPS. The Ultra preset at 4K is the only configuration that drops below 50 FPS (49 FPS average), making it the least desirable choice.

The recommendation hierarchy is clear: for 4K gaming, Medium is the sweet spot, as it delivers 70 FPS average with a 60 FPS minimum, ensuring no perceptible stutter, while Low at 81 FPS offers additional headroom but sacrifices visual quality. At 1440p, High is the recommended preset for most users, as 110 FPS average comfortably exceeds the 60 FPS baseline and provides a richer visual experience than Medium's 130 FPS. For 1080p, Ultra is viable at 138 FPS, but High at 169 FPS is the better choice for competitive play, offering a 31 FPS margin that could reduce input latency on high refresh rate panels. The min FPS data available for Medium presets (170 at 1080p, 110 at 1440p, 60 at 4K) indicates that this preset maintains stable frame pacing, whereas the High and Ultra presets lack min FPS data, suggesting they may exhibit more variance. Overall, the data supports Medium at 4K, High at 1440p, and High or Ultra at 1080p as the optimal settings per resolution.

How This Combo Ranks

In the database of tested combinations for Doom, this pairing of the Intel Core i7-14700KF and AMD Radeon RX 6700 XT holds a combo rank of 1951 out of 3712 total combos. This places it in the 52.6th percentile of all tested systems, meaning roughly 47% of combinations perform worse while 47% perform better. The rank reflects the system's balanced but not exceptional capability in this specific title. Given that the GPU sits in the 72nd percentile of all GPUs and the CPU in the 94th percentile of all CPUs, the combo's mid-pack ranking suggests that Doom's performance is more heavily influenced by the GPU than the CPU, as the RX 6700 XT's 72nd percentile standing drags the overall rank below what the CPU alone would suggest. The data shows that 4K Ultra performance (49 FPS) is the weakest link, and this likely contributes to the combo's middling rank, as other combinations with stronger GPUs would achieve higher FPS at that demanding preset.

The rank of 1951 indicates that this system is neither a top-tier performer nor a low-end option for Doom. It outperforms about half of the tested combos, which is consistent with the GPU's 72nd percentile score of 27425 and its near-tie with the NVIDIA GeForce RTX 3090 (delta of -0.5%). The fact that the combo ranks below the 50th percentile despite the CPU's high standing underscores that Doom is GPU-bound at most resolutions, and the RX 6700 XT's mid-range positioning in the GPU hierarchy (72nd percentile) is the primary determinant of the overall combo rank. For users seeking a higher rank, the data suggests that upgrading the GPU would yield more significant gains than upgrading the CPU, given the CPU's already strong 94th percentile position.

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor from the Raptor Lake architecture, built on Intel's 10 nm process with a die size of 257 mm². It operates with a base clock of 3.40 GHz and a boost clock of 5.60 GHz, and its cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. In synthetic benchmarks, this CPU achieves a Cinebench R23 multi-core score of 44167 and a single-core score of 6235, along with a Geekbench multi-core score of 21462 and a single-core score of 2578. Its PassMark multi-thread score is 52425, and its single-thread score is 4480, placing it in the 94th percentile of all CPUs. These figures indicate that the processor has ample compute headroom for Doom, a game that is not particularly CPU-intensive, and the measured FPS data supports this: at 1080p Low, the combo reaches 230 FPS, which is likely near the engine's frame-rate ceiling rather than a CPU limitation.

The CPU's nearest rivals in terms of average benchmark score include the AMD Ryzen 7 9700F (69996, delta of 0.2%), the AMD Ryzen 9 7940HX (69875, delta of 0.4%), and the AMD Ryzen 9 7950X (69515, delta of 0.9%). The i7-14700KF's average benchmark score of 70163 edges out all three, but the deltas are minimal, indicating that these processors would perform nearly identically in Doom given the same GPU. The CPU's 125 W TDP and support for DDR4 and DDR5 memory, along with PCIe Gen 5 with 16 lanes, provide a robust platform, but the game's performance is not sensitive to these factors. The fact that the combo's FPS at 1080p Low (230 FPS) is nearly double the 1080p Ultra figure (138 FPS) confirms that the GPU is the limiting component, as a CPU-bound scenario would show less variation across quality presets. The CPU's high single-thread performance (6235 in Cinebench R23) ensures that Doom's main-thread rendering logic does not bottleneck even at high frame rates, allowing the GPU to operate at its full potential.
