Doom

The AMD Ryzen 5 8400F and Intel Arc B570 combination presents a peculiar case for Doom: the data shows a system that is decisively playable at 1080p and 1440p, yet completely falls short of the 60 FPS threshold at 4K, regardless of settings. The measured frame rates reveal a clear performance ceiling that shifts dramatically with resolution, making this a study in how a mid-range CPU and GPU pair scale across the demands of a modern FPS title.

Similar Performance Alternatives

For the CPU, the AMD Ryzen 5 8400F sits in a tight cluster of processors with nearly identical average benchmark scores. The closest rival is the AMD Ryzen 5 7500F, which scores 24964 against the 8400F’s 25005, a delta of just 0.2%. This means that in CPU-bound scenarios, swapping to the 7500F would produce virtually indistinguishable frame rates. Two Intel mobile parts, the Core i7-11850H and Core i7-13620H, are also within a hair’s breadth, with scores of 24935 and 24911 respectively (0.3% and 0.4% delta). Interestingly, the AMD EPYC 9474F scores slightly higher at 25103, but that is a server-class chip and not a realistic alternative for a desktop gaming build. The key takeaway is that the 8400F’s performance envelope is well-defined: it is a solid mid-range part with no standout advantage or weakness relative to its nearest peers.

On the GPU side, the Intel Arc B570’s nearest rivals are a mix of mobile and older desktop parts. The NVIDIA GeForce RTX 3070 Mobile matches it almost exactly, scoring 20534 versus 20536, a 0.1% delta. The Intel Arc A750 is the only direct desktop competitor, with a score of 20582, which is 0.1% higher than the B570. This is notable because it implies the older A750 delivers comparable raw performance, making the B570 an incremental rather than generational leap. The other two rivals, the NVIDIA Quadro M4000M and AMD Radeon R9 M390X, are far older and score 20480 (0.4% delta) and 20662 (-0.5% delta) respectively, but they are not relevant for modern gaming. For Doom, the B570’s performance profile suggests that users coming from an RTX 3070 Mobile or Arc A750 would see nearly identical frame rates, assuming the rest of the system is unchanged.

CPU and GPU Roles

The measured FPS data for Doom indicates that the GPU is the dominant constraint at higher resolutions, while the CPU becomes relatively more important as resolution drops. At 3840x2160, the frame rates are consistently low: High settings yield 42 FPS, Medium 50 FPS, and even Low only reaches 57 FPS. This pattern strongly suggests the Arc B570 is saturated, as reducing settings from High to Low improves performance by only 15 FPS (from 42 to 57). If the CPU were the bottleneck, the scaling would be much flatter. The GPU’s 10 GB of memory and 380.0 GB/s bandwidth appear insufficient for the pixel throughput demanded at 4K, and the data confirms that no preset can push past the 60 FPS threshold.

At 2560x1440, the picture changes. The jump from 4K to 1440p is dramatic: High settings leap from 42 to 78 FPS, and Low goes from 57 to 106 FPS. This indicates that the GPU is now able to keep up with the reduced pixel count, and the CPU begins to show its strength. The spread between Low (106 FPS) and Ultra (64 FPS) is 42 FPS, which is a wider gap than at 4K, suggesting that the CPU can feed the GPU sufficiently at lower settings, but the GPU still struggles with the higher-quality presets. At 1920x1080, the CPU’s role becomes even more apparent. Low settings hit 164 FPS, while Ultra drops to 99 FPS; the gap is 65 FPS. The fact that Low nearly doubles Ultra’s frame rate implies that at 1080p, the Ryzen 5 8400F is capable of driving the game to very high frame rates, but the Arc B570’s rendering overhead at Ultra settings holds it back. In short, the CPU is sufficient for 1440p and 1080p gaming, but the GPU is the limiting factor at 4K and at high presets across all resolutions.

Best Settings per Resolution

The verdict data provides a clear answer for each resolution. At 3840x2160, there is no playable setting; the highest average FPS recorded is 57 at Low, which falls short of the 60 FPS threshold. The best settings field is null, confirming that 4K is simply not viable with this combo. At 2560x1440, all four settings—Low, Medium, High, and Ultra—are playable. The most demanding preset that stays at or above 60 FPS is Ultra, which delivers an average of 64 FPS. This is a tight margin, only 4 FPS above the threshold, but it is playable. At 1920x1080, the same pattern holds: all settings are playable, and the best is Ultra with an average of 99 FPS. That leaves a comfortable 39 FPS headroom, making 1080p Ultra the clear choice for a smooth experience. Notably, the Medium preset at 1080p shows a minimum FPS of 121 and maximum of 164, which suggests that even in demanding scenes, the frame rate never dips below the playable threshold.

Measured FPS Breakdown

The full dataset shows a consistent scaling pattern across resolutions. At 3840x2160, the frame rates are: Low 57 FPS, Medium 50 FPS (min 43, max 58), High 42 FPS, and Ultra 35 FPS. The spread from Low to Ultra is 22 FPS, which is modest and indicates the GPU is heavily taxed. At 2560x1440, the performance improves significantly: Low 106 FPS, Medium 92 FPS (min 79, max 106), High 78 FPS, and Ultra 64 FPS. The spread widens to 42 FPS, showing that settings have a larger impact as the GPU workload lightens. At 1920x1080, the frame rates are: Low 164 FPS, Medium 143 FPS (min 121, max 164), High 121 FPS, and Ultra 99 FPS. The spread is 65 FPS, the largest of any resolution, which demonstrates that at 1080p, the CPU can feed high frame rates, but the GPU’s rendering cost at Ultra limits the ceiling. Notably, the Medium preset at 1080p has a max FPS of 164, which matches the Low preset’s average, indicating that the GPU can occasionally hit very high frame rates even at medium quality, but the average is pulled down by heavier scenes.

How This Combo Ranks

In the grand scheme of tested hardware, this combo ranks 2987 out of 3712 combinations. This places it in the bottom 20% of all tested systems for Doom. The rank is a holistic measure that accounts for both the CPU and GPU’s performance across all resolutions and settings. Given that the combo is playable at 1080p and 1440p, the low rank might seem surprising, but it is likely dragged down by the complete failure at 4K. Many other combos likely achieve playable frame rates at 4K, which would push them higher in the rankings. The CPU’s percentile rank of 77 (above 77% of all CPUs) and the GPU’s percentile rank of 65 (above 65% of all GPUs) are both respectable, but the combination does not synergize well enough for top-tier performance. The 4K results, where even Low settings fail to hit 60 FPS, are the primary reason this combo sits so low.

The Verdict

Can this PC run Doom? The answer is conditional. At 1920x1080, the system is fully capable, with the Ultra preset delivering 99 FPS, well above the 60 FPS threshold. At 2560x1440, it also passes, with Ultra at 64 FPS, though the margin is slim. At 3840x2160, the system fails entirely; the best result is 57 FPS on Low, which is below the playable threshold, and no settings are listed as playable. The data implies that this combo is a strong 1080p machine and a decent 1440p machine, but it is not a 4K solution for Doom. The Ryzen 5 8400F provides ample CPU headroom, as evidenced by the high frame rates at 1080p Low, but the Arc B570’s 10 GB memory and 160-bit bus are insufficient for 4K’s demands. For users with a 1080p or 1440p monitor, this is a playable and even enjoyable setup for Doom; for 4K, it is a definitive miss.
