Doom

The AMD Ryzen 7 5700G paired with the Intel Arc B390 delivers a playable Doom experience at 1080p and 1440p, but it falls short of the 60 FPS threshold at 4K. Benchmark data confirms that this combination is best suited for 1080p Ultra settings, where it achieves an average of 64 FPS, while 1440p users will need to settle for Medium settings to maintain a consistent 60 FPS.

Best Settings per Resolution

At 1920x1080, the system clears the 60 FPS playability threshold across all four presets. The most demanding preset that remains at or above 60 FPS is Ultra, which produces an average of 64 FPS. This makes 1080p Ultra the optimal configuration for visual fidelity without sacrificing smooth gameplay. The data shows a clear progression: Low averages 107 FPS, Medium averages 93 FPS, and High averages 78 FPS, all comfortably above the target.

At 2560x1440, the situation tightens considerably. The highest preset that stays at or above 60 FPS is Medium, with an exact average of 60 FPS. Low averages 69 FPS, but High drops to 51 FPS and Ultra falls to 41 FPS, both below the playable threshold. The recorded minimum for Medium at this resolution is 51 FPS, indicating some frame dips below the average, but the average itself meets the requirement.

At 3840x2160, no preset achieves 60 FPS. The best recorded average is 37 FPS on Low settings, followed by 33 FPS on Medium, 28 FPS on High, and 22 FPS on Ultra. The database lists no playable settings for this resolution, meaning the system cannot maintain a smooth experience at 4K under any configuration.

CPU and GPU Roles

The scaling data reveals that the Intel Arc B390 is the primary bottleneck in this pairing, particularly at higher resolutions. The GPU's integrated design, with system-shared memory, limits its ability to push frames as resolution increases. At 1080p, the GPU has enough headroom to deliver 107 FPS on Low, but this drops to 69 FPS at 1440p and 37 FPS at 4K on the same preset, representing a 65% reduction from 1080p to 4K.

The CPU, an AMD Ryzen 7 5700G with 8 cores and 16 threads, is not the limiting factor here. Its benchmark scores, such as a Cinebench R23 multicore score of 12830.5, indicate ample processing power for a 2016 FPS title like Doom. The gap between Low and Ultra presets at each resolution shows GPU-bound behavior: at 1080p, the spread from Low to Ultra is 43 FPS (107 to 64), while at 1440p the spread narrows to 28 FPS (69 to 41), and at 4K it narrows further to 15 FPS (37 to 22). This compression at higher resolutions confirms that the GPU is saturated, and the CPU has spare capacity.

The GPU's 7.680 TFLOPS FP32 performance and 60.00 GPixel/s pixel rate are modest figures, and its 9th percentile ranking among all GPUs underscores its entry-level positioning. In contrast, the CPU ranks in the 79th percentile, a stark difference that makes the GPU the clear constraint in this system.

Similar Performance Alternatives

For the GPU, the nearest rivals in the database are all NVIDIA offerings with very similar 3DMark Steel Nomad scores. The GeForce GT 520MX scores 1463, just 1.3% below the Arc B390's 1482. The GeForce 800M is 1.5% behind, the GeForce GT 625 OEM is 2.5% behind, and the GeForce GT 710 is 2.7% behind. These deltas are small enough that a user swapping between any of these GPUs would see nearly identical frame rates in Doom, meaning the system's playability profile at 1080p and 1440p would remain largely unchanged.

For the CPU, the Ryzen 7 5700G sits within a tight cluster of rivals. The Intel Core i9-9900K has an average score of 27097, just 0.2% higher. The Intel Core i5-14400T scores 27166, 0.4% higher. The AMD Ryzen AI 7 445 scores 26936, 0.4% lower, and the Intel Core i7-1370P scores 26900, 0.6% lower. None of these processors would meaningfully alter Doom's performance, as the game is GPU-bound in this configuration. The CPU's 3DMark single-thread score of 899 and multicore score of 6629 are more than sufficient for this title's engine.

The Verdict

This PC can run Doom, but the experience depends heavily on resolution. At 1920x1080, the system is fully playable across all settings, with Ultra averaging 64 FPS and High averaging 78 FPS. This is the recommended configuration for the best balance of visual quality and smoothness. At 2560x1440, the system remains playable, but only on Low (69 FPS) or Medium (60 FPS) settings. The database confirms that High and Ultra fall below the 60 FPS threshold at this resolution.

At 3840x2160, the system cannot achieve 60 FPS on any preset. The best result is 37 FPS on Low, which is below the playable threshold. Gamers targeting 4K would need a significantly stronger GPU, as the Arc B390's performance ceiling is clearly defined by its 3DMark Steel Nomad score of 1482 and its 9th percentile ranking.

The recorded data shows that the 1080p Medium preset averages 93 FPS with a minimum of 79 FPS, providing a large safety margin above the threshold. For competitive play, 1080p Low at 107 FPS would be the smoothest option, but for single-player immersion, 1080p Ultra at 64 FPS is the best choice.

FAQ

Q: What is the best settings preset for 1080p on this system?

A: Ultra is the most demanding preset that stays at or above 60 FPS, with an average of 64 FPS. Low averages 107 FPS, Medium averages 93 FPS, and High averages 78 FPS.

Q: Can this system run Doom at 1440p?

A: Yes, but only on Low or Medium settings. Low averages 69 FPS and Medium averages 60 FPS. High and Ultra fall below the threshold at 51 FPS and 41 FPS respectively.

Q: Is the CPU or GPU the limiting factor at 4K?

A: The GPU is the clear bottleneck. The Arc B390's 9th percentile ranking and 7.680 TFLOPS FP32 performance cannot sustain 60 FPS at 3840x2160, where the best average is 37 FPS on Low. The CPU's 79th percentile ranking indicates it has spare capacity.

A: The GPU is 1.3% faster than the GeForce GT 520MX, 1.5% faster than the GeForce 800M, 2.5% faster than the GeForce GT 625 OEM, and 2.7% faster than the GeForce GT 710 in 3DMark Steel Nomad scores.

Q: What is the average FPS difference between Low and Ultra at 1080p?

A: The difference is 43 FPS, with Low averaging 107 FPS and Ultra averaging 64 FPS. This represents a 40% performance drop for the highest visual preset.

Q: Does the system have any playable settings at 4K?

A: No. The database lists no playable settings at 3840x2160. The highest average is 37 FPS on Low, which is well below the 60 FPS playable threshold.

How This Combo Ranks

This combination ranks 3300 out of 3712 tested combos for Doom, placing it in the lower 11% of all configurations in the database. This low ranking is driven almost entirely by the GPU, which sits in the 9th percentile among all GPUs. The CPU, by contrast, performs respectably with a 79th percentile ranking.

The rank reflects the system's limited headroom at higher resolutions. While it handles 1080p Ultra at 64 FPS, it cannot manage 1440p High or any 4K preset. Most of the 412 combos ranked below this one likely feature even weaker GPUs, while the 3300 above it offer superior graphics performance. For Doom specifically, the data suggests that any GPU with a higher 3DMark score would improve the ranking substantially, as the CPU is not a limiting factor. The 2016 release date of Doom means the engine is well-optimized, but the Arc B390's entry-level positioning caps the overall experience.
