Doom

The Intel Core i5-12400F paired with the AMD Radeon RX 7600 XT delivers a remarkably fluid experience in Doom, with the data showing that the game’s id Tech engine scales cleanly across settings and resolutions. For a 1080p setup, the Ultra preset is the clear choice, as it maintains an average of 118.3 FPS—well above the 60 FPS threshold for smooth play. At 1440p, the High preset offers the best trade-off, hitting 98 FPS average, while the Ultra preset still manages a respectable 77.7 FPS. At 4K, the situation tightens; the Low preset is the only one that keeps the average above 60 FPS at 67.9 FPS, making it the recommended option for that resolution if you demand a locked experience.

Settings Recommendations

The measured rows show a clear hierarchy: at 1080p, the gap between Low and Ultra is substantial, but the performance headroom is so large that Ultra is the obvious setting. The 118.3 FPS average at Ultra is 80.2 FPS higher than the same card’s 4K Ultra result, indicating the CPU and GPU have plenty of room to spare. For competitive play, the Low preset at 1080p yields 198.5 FPS, which minimizes input latency, but the visual fidelity loss is not necessary for a smooth experience. At 1440p, the Low preset (128 FPS) and Medium (114.8 FPS) are both viable, but High at 98 FPS still provides a comfortable margin above 60 FPS, making it the sweet spot for visual quality without sacrificing responsiveness. The Ultra preset at 1440p (77.7 FPS) is playable but begins to show the GPU’s limits. At 4K, the data is unambiguous: Low (67.9 FPS) is the only preset that clears the 60 FPS bar, while Medium (63.8 FPS) is a close second but still below the target. High (51.6 FPS) and Ultra (44.9 FPS) are not recommended for 4K unless you prioritize visuals over frame rate.

GPU Role

The AMD Radeon RX 7600 XT’s specifications directly explain the measured results. With a boost clock of 2755 MHz and a game clock of 2470 MHz, the card’s 2048 shading units are working hard, especially as resolution increases. The 16 GB of GDDR6 memory on a 128-bit bus with 288.0 GB/s bandwidth is ample for Doom’s textures, but the card’s 64 ROPs and 22.57 TFLOPS FP32 performance become the limiting factor at higher resolutions. The data shows that dropping from High to Low at 4K yields a 16.3 FPS average increase (from 51.6 to 67.9 FPS), which is a 31.6% improvement—this indicates that the GPU is bandwidth and fill-rate constrained at 4K, not VRAM constrained. The card’s 16 GB VRAM is never a bottleneck here; even at 4K Ultra, the game runs, albeit at 44.9 FPS. The PCIe 4.0 x8 interface is not a limiting factor in this title, as the frame rates scale predictably with resolution and settings, rather than showing CPU-side stalls.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and tells a clear story about the limiting component. At High settings, the average FPS falls from 145 at 1080p to 98 at 1440p (a 32.4% drop) and then to 51.6 at 4K (a 64.4% drop from 1080p). This pattern—where the 1440p to 4K drop is larger than the 1080p to 1440p drop—indicates that the RX 7600 XT runs out of pixel throughput at 4K, not that the i5-12400F is holding it back. The CPU’s 6 cores and 12 threads, with a boost clock of 4.40 GHz, are sufficient to feed the GPU at lower resolutions; the 1080p Low result of 198.5 FPS shows the CPU can drive high frame rates. At 1440p, the Ultra preset (77.7 FPS) is only 44.1 FPS lower than Low (128 FPS), suggesting the GPU is becoming the primary constraint. At 4K, the gap between Low (67.9 FPS) and Ultra (44.9 FPS) is 23 FPS, confirming that the GPU’s 176.3 GPixel/s pixel rate is the bottleneck.

Measured FPS Breakdown

At 1920x1080, the i5-12400F and RX 7600 XT combination produces excellent results across all presets. The Low preset averages 198.5 FPS, Medium drops to 177.2 FPS, High lands at 145 FPS, and Ultra still holds 118.3 FPS. The scaling from Low to Ultra is a 40.4% reduction in frame rate, which is modest given the visual uplift. Moving to 2560x1440, the averages are 128 FPS (Low), 114.8 FPS (Medium), 98 FPS (High), and 77.7 FPS (Ultra). The drop from 1080p to 1440p at High is 47 FPS, a 32.4% decrease, which is consistent with the increased pixel count. At 3840x2160, the results are 67.9 FPS (Low), 63.8 FPS (Medium), 51.6 FPS (High), and 44.9 FPS (Ultra). The 4K Ultra result is 73.4 FPS lower than the 1080p Ultra result, highlighting the GPU’s struggle at this resolution. None of the 4K presets exceed 68 FPS, so users with 4K displays will need to accept either Low settings or a lower resolution.

How This Combo Ranks

The combo ranks 1068 out of 1681 tested combinations in Doom, placing it in the lower-middle tier of the database. This ranking reflects the GPU’s position in the overall market: the RX 7600 XT has a percentile rank of 63 against all GPUs, meaning it outperforms a majority of cards but is not a top-tier part. The CPU, on the other hand, has a percentile rank of 77 against all CPUs, showing it is a strong mid-range processor. The delta between the two components—with the CPU being more capable than the GPU—explains why the combo is not ranked higher; the GPU is the limiting factor, especially at higher resolutions. Compared to the GPU’s nearest rivals, the data shows a mixed bag: the RX 7600 XT is 0.3% faster than the Radeon RX 460, 0.6% slower than the RX 7600, 1.9% faster than the RTX 2060 SUPER, and 1.9% slower than the RTX 3070 Mobile. These small deltas suggest that the RX 7600 XT is a very tightly contested card, and the combo’s rank is more about the GPU’s absolute performance than any pairing inefficiency.

FAQ

Q: What is the best preset for 1440p gaming with this combo?

A: The High preset is the best choice, delivering an average of 98 FPS. This provides a solid margin above 60 FPS while offering better visual fidelity than Medium (114.8 FPS) or Low (128 FPS). Ultra at 1440p drops to 77.7 FPS, which is still playable but not ideal.

Q: Can this setup handle 4K gaming at 60 FPS?

A: No, not at any preset. The highest 4K result is 67.9 FPS on Low settings, but that is the only preset above 60 FPS. Medium (63.8 FPS) is close, but High (51.6 FPS) and Ultra (44.9 FPS) fall short of the 60 FPS target.

Q: How does the RX 7600 XT compare to the RX 7600 in this context?

A: The RX 7600 XT is 0.6% slower than the RX 7600 based on average benchmark scores. In practical terms, this means the two cards will perform nearly identically in Doom, with differences of only a few frames per second.

Q: Is the 16 GB VRAM on the RX 7600 XT useful for Doom?

A: The 16 GB of GDDR6 memory is not a limiting factor in this game. The performance drop from 1080p to 4K is consistent with pixel throughput limitations, not VRAM capacity. Even at 4K Ultra, the game runs without VRAM-related stutters, though frame rates are low.

Q: What is the CPU’s role in this combo’s performance?

A: The Intel Core i5-12400F, with 6 cores and 12 threads, is not a bottleneck at 1080p, as evidenced by the 198.5 FPS Low result. At 1440p and 4K, the GPU becomes the limiting factor, with the CPU providing enough headroom to feed the RX 7600 XT effectively.

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

A: It ranks 1068 out of 1681 combinations in Doom, placing it in the lower-middle tier. This is driven by the GPU’s mid-range performance (63rd percentile) rather than the CPU, which is stronger (77th percentile). The GPU is the primary constraint on frame rates.
