Doom

Best Settings per Resolution

At 1920x1080, the Intel Core i5-9400 with Intel Arc B570 can run Doom at Ultra settings with an average of 99 FPS. This is the most demanding preset that stays at or above the 60 FPS playability threshold, and it clears that mark by a comfortable 39 FPS. Lower presets push the frame rate even higher, with High at 121 FPS, Medium at 143 FPS, and Low at 164 FPS, but Ultra is the maximum visual quality that remains fully playable.

At 2560x1440, the same conclusion applies: Ultra settings deliver an average of 64 FPS, which is just above the 60 FPS threshold. The margin is thinner than at 1080p, but it is still a valid choice for maximum image quality. The recorded data shows High at 78 FPS, Medium at 92 FPS, and Low at 106 FPS, all above the playability line, yet Ultra remains the best pick because it offers the highest fidelity without dropping below the target.

At 3840x2160, the situation changes decisively. The verdict data lists no playable settings at this resolution. The best recorded average is 57 FPS on Low, which falls short of 60 FPS. Medium averages 50 FPS, High averages 42 FPS, and Ultra averages 35 FPS. None of these clear the threshold, so the database does not designate a best setting for 4K. Users targeting 2160p must accept sub-60 performance or lower the resolution.

CPU and GPU Roles

The scaling between resolutions and presets reveals where the bottleneck lies for this pairing. At 1920x1080, the GPU is the dominant factor, but the CPU still has headroom. The jump from Low (164 FPS) to Ultra (99 FPS) is a 65 FPS drop, a 40% reduction in average frame rate, which indicates the graphics load is the primary lever. The CPU, a 6-core, 6-thread Coffee Lake part with a 4.10 GHz boost clock, is not the limiting factor at this resolution, as even the most demanding preset stays well above 60 FPS.

Moving to 2560x1440, the GPU becomes more stressed. The spread from Low (106 FPS) to Ultra (64 FPS) is 42 FPS, a 40% drop again, but the absolute numbers are lower across the board. Compared to 1080p, every preset loses roughly 35 to 40 FPS, which is a direct consequence of the increased pixel count. The CPU still delivers enough throughput, but the Arc B570, with its 10 GB GDDR6 memory and 380.0 GB/s bandwidth, is now the clear constraint. The GPU's 65th percentile ranking among all GPUs supports this interpretation.

At 3840x2160, the GPU is overwhelmingly the limiting component. The best average, 57 FPS on Low, is below the 60 FPS threshold, and the drop from Low to Ultra is 22 FPS, a 39% reduction. The CPU's role diminishes further because the frame rate is capped by the graphics pipeline. The data shows that the i5-9400, which sits at the 47th percentile among all CPUs, does not prevent the GPU from reaching its limits at any resolution; the Arc B570 simply cannot push enough pixels at 2160p to maintain playability. In short, the GPU dictates performance at 1440p and 2160p, while the CPU is sufficient at 1080p and above.

Measured FPS Breakdown

1920x1080

• Low: Average 164 FPS, no minimum or maximum recorded.
• Medium: Average 143 FPS, minimum 121 FPS, maximum 164 FPS.
• High: Average 121 FPS, no minimum or maximum recorded.
• Ultra: Average 99 FPS, no minimum or maximum recorded.

The Medium preset shows the only full range in the 1080p set, with a minimum of 121 FPS that still far exceeds the 60 FPS threshold. The gap between Low and Ultra is 65 FPS, and every preset is comfortably playable.

2560x1440

• Low: Average 106 FPS, no minimum or maximum recorded.
• Medium: Average 92 FPS, minimum 79 FPS, maximum 106 FPS.
• High: Average 78 FPS, no minimum or maximum recorded.
• Ultra: Average 64 FPS, no minimum or maximum recorded.

At 1440p, the Medium preset again provides the only min/max data, with a minimum of 79 FPS. The Ultra preset's 64 FPS average is the lowest playable value in the entire dataset, but it still clears the threshold by 4 FPS.

3840x2160

• Low: Average 57 FPS, no minimum or maximum recorded.
• Medium: Average 50 FPS, minimum 43 FPS, maximum 58 FPS.
• High: Average 42 FPS, no minimum or maximum recorded.
• Ultra: Average 35 FPS, no minimum or maximum recorded.

At 4K, the Medium preset shows a minimum of 43 FPS and a maximum of 58 FPS, meaning even the best frame in that run falls below the threshold. The Low preset's 57 FPS average is the closest any setting comes to playability, but the database records no playable settings at this resolution.

Similar Performance Alternatives

For the CPU, the Intel Core i5-9400 has an average benchmark score of 2254, which places it at the 47th percentile among all CPUs. Its nearest rivals in the database are extremely close in performance. The Intel Core i7-1068NG7 scores 2259, a 0.2% difference, meaning it would behave nearly identically in Doom. The Intel Core i7-10710U scores 2248, 0.3% lower, and the AMD Ryzen 5 PRO 1500 scores 2246, 0.4% lower. The Intel Core i3-10305 scores 2264, 0.4% higher. In practical terms, any of these CPUs would deliver the same frame rates as the i5-9400 in this game, because the GPU is the limiting factor at higher resolutions and the CPU has ample headroom at 1080p.

For the GPU, the Intel Arc B570 has an average benchmark score of 20556, placing it at the 65th percentile among all GPUs. Its nearest rivals are also tightly clustered. The NVIDIA GeForce RTX 3070 Mobile scores 20534, just 0.1% lower, so it would produce nearly the same FPS in Doom at every resolution and preset. The Intel Arc A750 scores 20582, 0.1% higher, making it a slightly faster alternative with the same performance profile. The NVIDIA Quadro M4000M scores 20480, 0.4% lower, and the AMD Radeon R9 M390X scores 20662, 0.5% higher. All of these GPUs would land within a fraction of a percent of the Arc B570's measured results, meaning users with any of these cards should expect the same playability verdict: 1080p and 1440p at Ultra, but no playable settings at 2160p.

FAQ

Q: Can this PC run Doom at 1920x1080 with maximum settings?

A: Yes. The Intel Core i5-9400 with Intel Arc B570 achieves an average of 99 FPS at 1080p Ultra, which is well above the 60 FPS playability threshold.

Q: What is the best preset at 2560x1440?

A: Ultra is the best preset at 1440p, with an average of 64 FPS. This is the highest visual quality that still clears the 60 FPS line.

Q: Is 3840x2160 playable with this hardware?

A: No. The database records no playable settings at 2160p. The best average is 57 FPS on Low, which falls short of the 60 FPS threshold.

Q: How much performance is lost when going from 1080p to 1440p?

A: At Ultra settings, the average drops from 99 FPS at 1080p to 64 FPS at 1440p, a 35 FPS reduction. At Low settings, the drop is from 164 FPS to 106 FPS, a 58 FPS reduction.

Q: Which component limits performance at 4K?

A: The GPU is the limiting factor. The Intel Arc B570 cannot maintain 60 FPS at 2160p even on Low settings, while the CPU, a 6-core part at the 47th percentile, is not the bottleneck.

Q: How does the Intel Arc B570 compare to the Arc A750 in Doom?

A: The Arc A750 has an average benchmark score of 20582, which is 0.1% higher than the Arc B570's 20556. In Doom, this translates to virtually identical frame rates at all resolutions and presets.

The Verdict

The Intel Core i5-9400 with Intel Arc B570 can run Doom at 1920x1080 and 2560x1440 with playable performance, but it cannot handle 3840x2160. At 1080p, the verdict data lists High, Low, Medium, and Ultra as playable, with Ultra being the best setting at 99 FPS. At 1440p, all four presets are also playable, with Ultra at 64 FPS as the best choice. At 2160p, the verdict is clear: no settings are playable, as even Low falls below the 60 FPS threshold with a 57 FPS average.

For users who prioritize 1080p or 1440p gaming, this combination delivers smooth performance at maximum quality. The 99 FPS average at 1080p Ultra leaves room for high refresh rate displays, and the 64 FPS average at 1440p Ultra is adequate for standard 60 Hz monitors. The only limitation is 4K, where the GPU's 10 GB memory and 380.0 GB/s bandwidth are insufficient to maintain playable frame rates. The CPU, with its 6 cores and 6 threads, is never the limiting factor in this game, as evidenced by the consistent GPU-bound behavior across resolutions. Overall, this PC is a solid choice for Doom at mainstream resolutions, but not for 2160p gaming.
