Doom

The pairing of the Intel Core i7-14700F with the AMD Radeon RX 570 presents a stark contrast in capabilities: a high-end, modern 20-core processor from the Core 14th Gen series driving a 2017-era, 4 GB graphics card built on the GCN 4.0 architecture. In Doom, the benchmark results clearly demonstrate that this system’s performance ceiling is defined almost entirely by the graphics card, with the CPU’s substantial processing headroom left largely untapped. The data paints a clear picture of a system that is severely GPU-limited at every resolution tested, making the RX 570 the definitive bottleneck.

Resolution Scaling

The performance drop from 1080p to 4K is significant and reveals the classic profile of a GPU-bound workload. At the High preset, the average frame rate falls from 66.8 FPS at 1920x1080 to 43.6 FPS at 2560x1440, a 34.7% reduction, and then plunges further to 26.6 FPS at 3840x2160. This steep decline is characteristic of a system where the GPU’s fill rate and memory bandwidth are the limiting factors, rather than the CPU’s ability to feed the renderer with draw calls. Even with the Low preset, the scaling pattern holds: 90.9 FPS at 1080p drops to 60.6 FPS at 1440p and then to 30.3 FPS at 4K. The halving of performance from 1080p to 4K at Low settings underscores how much work the Polaris 20 chip must do as pixel count quadruples, pushing the GPU to its absolute limits regardless of the graphical workload.

The reduction in frame rate between 1440p and 4K is proportionally larger than the drop between 1080p and 1440p, which is expected given the pixel count increase from roughly 3.7 million to 8.3 million. This non-linear scaling indicates that the RX 570’s 224.0 GB/s of memory bandwidth and 32 ROPs become increasingly insufficient as resolution rises. The data suggests that for this combination, the limiting component is unequivocally the graphics card. The i7-14700F, with its 28 threads and boost clock of 5.40 GHz, is more than capable of maintaining high frame rates in a 2016 title like Doom; the bottleneck is the GPU’s raw rendering throughput.

GPU Role

The AMD Radeon RX 570’s role in this pairing is to provide the graphical horsepower, and its specifications directly explain the measured results. With a 4 GB frame buffer of GDDR5 memory on a 256-bit bus, the card offers 224.0 GB/s of bandwidth. This is a modest allocation for 4K gaming, and the data confirms the GPU struggles under that load. At 3840x2160, even the Low preset only yields 30.3 FPS, suggesting that the card is not just fill-rate limited but also potentially hitting memory capacity or bandwidth constraints. The GPU’s clocks, with a base of 1168 MHz and a boost of 1244 MHz, are relatively low by modern standards, and its FP32 performance of 5.095 TFLOPS is simply not enough to drive high frame rates at 4K in a demanding FPS title.

The GPU’s average benchmark score of 30158 places it in the 74th percentile of all GPUs, but its nearest rivals are modern cards like the NVIDIA GeForce RTX 5060 and AMD Radeon RX 7700 XT, which have average scores of 30109 and 30097, respectively. The deltaPct values are remarkably small (0.2% for both), indicating that the RX 570’s synthetic benchmark score is statistically on par with these much newer cards, despite being end-of-life and from a previous generation. However, in real-world gaming at higher resolutions, the 4 GB memory limit and older architecture likely prevent it from matching those newer cards in actual playable scenarios. The data shows that while the GPU holds its own in certain synthetic tests, its memory capacity and bandwidth are critical weaknesses that manifest in the 4K results, where it fails to achieve a playable 30 FPS on any preset above Low.

How This Combo Ranks

In the broader context of all tested combinations, this specific pairing of the i7-14700F and RX 570 ranks near the very bottom. The combo rank for Doom is 1638 out of 1681 possible combinations, placing it in the 2.6th percentile of all systems tested. This low ranking is a direct consequence of the GPU’s limitations, as the CPU’s performance is not a contributing factor. The i7-14700F’s average benchmark score of 54097 places it in the 94th percentile of all CPUs, with its nearest rival, the AMD Ryzen 9 9900X, scoring 54450 and showing a negligible deltaPct of -0.6%. This indicates the CPU is a top-tier performer, yet its pairing with a 74th-percentile GPU creates a massive imbalance.

The ranking suggests that in this configuration, the system behaves as if it were a low-end gaming PC, despite having a high-end processor. The data implies that any other GPU in the test pool, even those with average scores closer to the RX 570, would likely yield a better gaming experience. The fact that there are only 43 combinations ranked lower than this one highlights how severely the GPU holds back the rest of the system. From a benchmark database perspective, this combo is an example of extreme bottlenecking, where the processor’s potential is effectively wasted due to the graphics card’s inability to keep up with its output. The CPU’s fast processing speed is irrelevant when the GPU cannot render frames fast enough to utilize it.

Settings Recommendations

Given the measured FPS data, the optimal settings for this combination depend heavily on the target resolution and desired frame rate. At 1920x1080, the Medium preset provides a solid balance, delivering 82 FPS on average. This is a playable and smooth experience for a fast-paced FPS. The High preset at 1080p also remains viable at 66.8 FPS, though the drop from Medium is noticeable. The Ultra preset at 1080p yields 55.2 FPS, which is acceptable but may not be ideal for competitive play where higher refresh rates are preferred. The Low preset at 1080p achieves 90.9 FPS, but the visual fidelity reduction is likely too steep for most users to justify the frame rate gain over Medium.

At 2560x1440, the situation becomes more constrained. The Low preset is the only setting that breaks the 60 FPS threshold, achieving 60.6 FPS. The Medium preset drops to exactly 50 FPS, which is still playable but not optimal. High and Ultra are less favorable, with 43.6 and 34.8 FPS respectively, making them borderline for a smooth experience. For 4K gaming at 3840x2160, no preset is truly playable. The Low preset achieves 30.3 FPS, which is on the edge of playability for some, but the Medium and High presets fall to 29.1 and 26.6 FPS, and Ultra drops to a stuttery 17.6 FPS. The data suggests that 1080p Medium or High is the best experience for this system, offering a good balance of visual quality and performance. For 1440p, users should stick to Low settings to maintain fluidity.

Measured FPS Breakdown

The complete set of measured frame rates provides a detailed look at the system’s performance envelope. At 1920x1080, the Ultra preset delivers an average of 55.2 FPS, while High improves to 66.8 FPS. Medium yields 82 FPS, and Low reaches 90.9 FPS. This progression shows a clear 64.7% improvement from Ultra to Low, indicating that the GPU has significant headroom at this resolution when settings are reduced. At 2560x1440, the averages are 34.8 FPS for Ultra, 43.6 FPS for High, 50 FPS for Medium, and 60.6 FPS for Low. The transition from 1080p to 1440p results in a performance hit of roughly 30% across all settings, which aligns with the increased pixel workload. At 3840x2160, the results are as follows: Ultra averages 17.6 FPS, High averages 26.6 FPS, Medium averages 29.1 FPS, and Low averages 30.3 FPS.

The data reveals that at 4K, the performance ceiling is extremely low, with even the lowest settings failing to reach 31 FPS. The difference between Medium and Low at 4K is minimal (only 1.2 FPS), suggesting that the GPU is hitting a hard limit, likely due to memory bandwidth or pixel fill rate. At 1440p, the jump from Medium to Low is a 21.2% increase, but at 4K, that same jump is only a 4.1% increase. This compression of performance at high resolutions indicates that the RX 570’s resources are exhausted, and reducing settings provides diminishing returns. The measured data confirms that this system is well-suited for 1080p gaming with medium-to-high settings, but it is not capable of delivering a smooth experience at higher resolutions, regardless of the graphical preset.
