Doom

The Intel Core i5-12400F and AMD Radeon RX 570 pairing delivers a distinctly mid-range experience in Doom, a 2016 FPS that scales predictably across resolutions and presets. The data shows this combination is capable of smooth 1080p play but struggles to maintain playable frame rates at higher resolutions, with the CPU rarely acting as the primary bottleneck.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-12400F is a 6-core, 12-thread processor based on the Alder Lake architecture, built on a 10 nm process. Its base clock of 2.50 GHz can boost up to 4.40 GHz, providing a solid foundation for gaming workloads. In synthetic benchmarks, the chip scores 16,518 in Cinebench R23 multi-core and 2,332 in single-core, placing it in the 77th percentile of all CPUs tested. The 18 MB of shared L3 cache and dual-channel memory support (DDR4 or DDR5) contribute to its responsiveness, but in Doom, the CPU’s headroom is rarely challenged.

Benchmark results indicate that the i5-12400F sits in a tight competitive cluster. It trails the AMD EPYC 7773X by 1.3% in average benchmark score, while edging out the Intel Core i7-8700K by 0.1% and the Intel Core i5-1335U by 0.3%. The AMD Ryzen 5 7533HS is 0.7% ahead. This near-parity means that the CPU is effectively a non-factor in determining frame rate differences at most settings; the measured FPS deltas across the board are far larger than any variance this processor could introduce.

At 1080p with Low settings, the combo hits 91.3 FPS average, which is substantially higher than the 55.7 FPS observed at Ultra. This 35.6 FPS gap is driven almost entirely by GPU load, not CPU capability. The i5-12400F’s 12 threads and high boost clock are more than sufficient to feed the RX 570 in this title, even in demanding combat sequences. The data suggests that the processor’s performance ceiling is well above what the GPU can deliver, meaning any frame rate drop when increasing settings or resolution is attributable to the graphics card, not the CPU.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 570 is a GCN 4.0 architecture GPU with 2,048 shading units, 128 TMUs, and 32 ROPs. Its base clock of 1168 MHz boosts to 1244 MHz, and the 4 GB of GDDR5 memory runs at 1750 MHz (7 Gbps effective) across a 256-bit bus, yielding 224.0 GB/s of bandwidth. The card’s 5.095 TFLOPS of FP32 performance and 159.2 GTexel/s texture rate are modest by modern standards, but the data shows they are adequate for Doom at lower resolutions.

The GPU’s synthetic benchmark scores place it in the 74th percentile of all GPUs, with an average score of 30,158. Its nearest rivals include the NVIDIA GeForce RTX 5060 (0.2% faster), AMD Radeon RX 7700 XT (0.2% faster), NVIDIA Tesla M60 (0.6% faster), and NVIDIA GeForce RTX 5070 Mobile (0.8% faster). This positioning indicates that the RX 570 is a competent entry-level card, but its age is evident in demanding scenarios.

In Doom, the GPU is clearly the limiting component. At 1080p, the jump from Low to Ultra settings drops average FPS from 91.3 to 55.7, a 35.6 FPS reduction that correlates directly with increased pixel and texture work. The 4 GB VRAM capacity appears sufficient at 1080p, but at 4K Ultra, the card’s 20.2 FPS average suggests that both memory bandwidth and raw compute are overwhelmed. The 224.0 GB/s bandwidth is a likely constraint at higher resolutions, where the GPU must shuffle significantly more data per frame.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured data provides clear guidance on which preset offers the best balance of visual quality and performance. At 1920x1080, the Medium preset delivers 79.8 FPS average, which is within striking distance of the 91.3 FPS achieved on Low while offering noticeably better visuals. High settings drop to 66.9 FPS, still playable, but the 12.9 FPS penalty over Medium is a meaningful step down for a modest visual gain. Ultra falls to 55.7 FPS, which is the first preset to dip below the 60 FPS threshold, making it less ideal for fast-paced action.

At 2560x1440, the situation becomes more constrained. Low settings produce 59.6 FPS, just under the 60 FPS target, while Medium yields 53.0 FPS and High drops to 47.0 FPS. Ultra at 1440p is a poor choice, averaging only 38.1 FPS. For a smooth experience at this resolution, Low is the only viable preset, and even then, the frame rate is marginal.

At 4K (3840x2160), none of the presets achieve playable performance. Low averages 30.7 FPS, Medium 30.5 FPS, and High 26.1 FPS, while Ultra falls to 20.2 FPS. Given these numbers, the best recommendation is to run Doom at 1080p with the Medium preset, as it provides the highest frame rate that still exceeds 60 FPS while offering superior quality to Low. If the user prioritizes frame rate above all, Low at 1080p is the only preset that approaches the 90 FPS mark.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combined Intel Core i5-12400F + AMD Radeon RX 570 configuration ranks 1,596 out of 1,681 tested combos in Doom. This places it in the bottom 5% of all systems evaluated, which is a surprisingly low standing given the individual component benchmarks. The CPU’s 77th percentile and the GPU’s 74th percentile suggest a mid-tier pairing, but the measured in-game results are heavily weighted by the GPU’s struggles at higher resolutions.

The rank implies that most other tested combos deliver higher average frame rates across the resolution and settings matrix. This is consistent with the RX 570’s age and the demanding nature of 4K benchmarks. The CPU’s strong relative performance (nearly tied with the i7-8700K) does little to offset the GPU’s limitations, as the frame rates are predominantly GPU-bound in every measured scenario. The low rank is not an indictment of the CPU, but rather a reflection of the GPU’s inability to keep pace with modern expectations.

Compared to the GPU’s nearest rivals, the RX 570’s average score of 30,158 is nearly identical to the RTX 5060 (30,109) and RX 7700 XT (30,097), yet the measured Doom performance suggests these newer cards would likely fare better due to architectural improvements not captured in synthetic averages. The data shows that this combo is best suited for 1080p gaming, where it can compete, rather than higher resolutions where it falls behind the pack.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The frame rate scaling across resolutions is stark and reveals the GPU as the definitive bottleneck. At High settings, the average FPS drops from 66.9 at 1080p to 47.0 at 1440p, a 19.9 FPS reduction, and then to 26.1 at 4K, a further 20.9 FPS drop. This pattern is consistent across all presets: Low goes from 91.3 at 1080p to 59.6 at 1440p (a 31.7 FPS loss) then to 30.7 at 4K (a 28.9 FPS loss). Medium drops from 79.8 to 53.0 to 30.5, and Ultra falls from 55.7 to 38.1 to 20.2.

The percentage drops are telling. From 1080p to 1440p, the average FPS loss across presets is roughly 30-35%, while from 1440p to 4K, the loss is another 45-50%. This accelerating decline indicates that the GPU’s compute and memory bandwidth are exhausted well before 4K, with the 224.0 GB/s bandwidth and 5.095 TFLOPS proving insufficient for the increased pixel count. The CPU’s performance is static across resolutions, as its workload does not scale with resolution in the same way, so the frame rate collapse is entirely attributable to the RX 570.

The data suggests that the i5-12400F has ample headroom even at 1080p Low, where the 91.3 FPS result is likely near the GPU’s maximum output rather than CPU-limited. At 4K, the 20-30 FPS range is firmly in slideshow territory, indicating that this combo should be firmly restricted to 1080p for any serious play. The resolution scaling confirms that upgrading the GPU would yield immediate dividends, while the CPU could remain in place for years without becoming a constraint in Doom.
