Doom

The AMD Ryzen 5 5600 paired with the Intel Arc B390 delivers a playable experience in Doom at 1080p and 1440p, but falls short of the 60 FPS threshold at 4K across all tested presets. At 1080p, the combination is fully playable on every preset including Ultra, while 1440p offers playable performance on Low and Medium settings. The recorded data shows a clear performance ceiling that aligns with the hardware's benchmark percentiles: the CPU sits in the 74th percentile among all tested processors, while the GPU ranks in the 9th percentile among all tested graphics cards.

Measured FPS Breakdown

At 1920x1080, the recorded frame rates range from a low of 64 FPS on Ultra to a high of 107 FPS on Low. The Medium preset averages 93 FPS with a minimum of 79 FPS and a maximum of 107 FPS. High settings deliver 78 FPS on average. The scaling from Low to Ultra at this resolution is steady: each step up in quality reduces the average by roughly 14 to 15 FPS, with the largest single drop occurring between Medium (93 FPS) and High (78 FPS). The Ultra preset still clears the 60 FPS playability threshold with 64 FPS, leaving only 4 FPS of headroom above the minimum acceptable average.

At 2560x1440, performance drops noticeably but remains playable on two presets. Low settings produce 69 FPS on average, Medium produces 60 FPS with a minimum of 51 FPS and a maximum of 69 FPS, High produces 51 FPS, and Ultra produces 41 FPS. The transition from Medium to High at this resolution is the most significant single-step loss in the entire dataset: a 9 FPS drop from 60 to 51 FPS, which pushes the average below the 60 FPS threshold. The Medium preset lands exactly on the playability line, meaning any scene complexity above the tested average could push it under 60 FPS, as evidenced by the recorded 51 FPS minimum.

At 3840x2160, no preset reaches the playable threshold. Low settings average 37 FPS, Medium averages 33 FPS with a minimum of 28 FPS and a maximum of 37 FPS, High averages 28 FPS, and Ultra averages 22 FPS. The gap between the best 4K result (37 FPS on Low) and the 60 FPS threshold is 23 FPS, which represents a 38% shortfall. The data shows that even the least demanding preset at 4K cannot sustain a playable frame rate, and the Ultra preset falls to nearly one-third of the target performance.

The measured FPS values follow a consistent pattern across resolutions. The spread between Low and Ultra at 1080p is 43 FPS (107 to 64), at 1440p it is 28 FPS (69 to 41), and at 4K it is 15 FPS (37 to 22). This narrowing spread at higher resolutions indicates that the GPU becomes the limiting factor more aggressively as pixel count increases, compressing the performance difference between quality presets.

CPU and GPU Roles

The division of labor between the AMD Ryzen 5 5600 and the Intel Arc B390 shifts dramatically depending on resolution. At 1080p, the CPU's strength is evident: the Ryzen 5 5600's 3DMark single-thread score of 882 and multi-thread score of 5659 provide enough processing headroom to let the GPU work through lower pixel counts efficiently. The 43 FPS spread between Low and Ultra at 1080p shows that the GPU still has performance to give as settings are reduced, meaning the CPU is not the primary bottleneck at this resolution.

At 1440p, the balance shifts toward the GPU. The 28 FPS spread between Low and Ultra is narrower than at 1080p, indicating that the GPU is starting to saturate. The Medium preset hitting exactly 60 FPS while Low reaches 69 FPS suggests that the GPU's compute resources, specifically its 7.680 TFLOPS FP32 throughput and 120.0 GTexel/s texture rate, are approaching their ceiling. The CPU continues to feed the GPU adequately, as evidenced by the fact that Low settings still improve performance meaningfully over Medium.

At 4K, the GPU dominates the performance equation entirely. The spread between Low (37 FPS) and Ultra (22 FPS) is only 15 FPS, which is the smallest gap across all resolutions. This compression indicates that the GPU is fully saturated even at Low settings, and the pixel rate of 60.00 GPixel/s combined with 24 ROPs becomes the hard limiting factor. The CPU's role at 4K is essentially to stay out of the way; the Ryzen 5 5600's 6 cores and 12 threads are more than sufficient to keep the frame pipeline fed, but no amount of CPU headroom can overcome the GPU's raw pixel throughput limits.

The scaling between resolutions confirms this interpretation. Moving from 1080p to 1440p on Medium settings reduces the average from 93 FPS to 60 FPS, a 35% drop. Moving from 1440p to 4K on Medium reduces the average from 60 FPS to 33 FPS, a 45% drop. The larger percentage drop at higher resolutions indicates that the GPU is increasingly the bottleneck, as pixel count grows faster than the GPU's ability to process it. The CPU's 3dmark max-thread score of 5659 and Cinebench R23 multi-core score of 18309 place it well above the demands of Doom, which is a 2016 title with modest CPU requirements.

How This Combo Ranks

The combination of AMD Ryzen 5 5600 and Intel Arc B390 ranks 3300 out of 3712 tested combos in Doom, placing it in the bottom 11% of all configurations in the database. This ranking is heavily driven by the GPU's performance class. The Intel Arc B390 scores 1482 in 3DMark Steel Nomad DX12, which places it in the 9th percentile among all GPUs. Its nearest rivals in the database are the NVIDIA GeForce GT 520MX (1463, 1.3% slower), NVIDIA GeForce 800M (1460, 1.5% slower), NVIDIA GeForce GT 625 OEM (1446, 2.5% slower), and NVIDIA GeForce GT 710 (1443, 2.7% slower). These are all entry-level or legacy mobile-class GPUs, which contextualizes the Arc B390's position as a very low-end graphics solution.

The CPU, by contrast, is a strong performer. The Ryzen 5 5600 scores 20468 on average across its benchmark suite, ranking in the 74th percentile among all CPUs. Its nearest rivals are the Intel Core Ultra 7 258V (20454, 0.1% slower), AMD Ryzen 5 8500G (20425, 0.2% slower), AMD EPYC 9454P (20422, 0.2% slower), and AMD EPYC 7713 (20363, 0.5% slower). The CPU's performance is essentially at parity with these rivals, with deltas under 0.5%, meaning the processor is not the factor holding this combo back.

The 3300th rank out of 3712 combos reflects the extreme imbalance between the two components. The CPU is a mid-range desktop part capable of handling modern games, while the GPU is an integrated-class solution with a 3nm Xe3-LPG architecture that targets low-power or portable devices. The database results show that this pairing produces playable 1080p performance in Doom, but the combo rank places it far below configurations with discrete GPUs, even those from several generations ago.

The Verdict

Can this PC run Doom? Yes, but only at specific resolutions and presets. At 1920x1080, all four presets are playable: Low (107 FPS), Medium (93 FPS), High (78 FPS), and Ultra (64 FPS). The Ultra preset clears the 60 FPS threshold with a 4 FPS margin, making 1080p the only resolution where players can max out the game's settings and still maintain playable frame rates.

At 2560x1440, two presets are playable: Low (69 FPS) and Medium (60 FPS). The Medium preset sits exactly at the 60 FPS threshold, so it is technically playable but leaves no margin for demanding scenes. The recorded minimum of 51 FPS on Medium suggests that gameplay could dip below 60 FPS during intense combat sequences. High (51 FPS) and Ultra (41 FPS) fall short of the threshold.

At 3840x2160, no preset is playable. The best result is Low at 37 FPS, which is 23 FPS below the threshold. The verdict data confirms this: there are zero playable settings at 4K, and no best settings are recommended for that resolution. Players targeting 4K would need to significantly reduce resolution scaling or accept sub-60 FPS performance, though the data shows the GPU simply does not have the pixel throughput for this title at that resolution.

The 60 FPS playability threshold is met at 1080p on all presets and at 1440p on Low and Medium. The system delivers a smooth experience at 1080p with headroom, a borderline experience at 1440p on Medium, and an unplayable experience at 4K.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which averages 64 FPS. This is the maximum quality configuration available in the game, and it runs with only 4 FPS of headroom above the playability threshold. Players who prefer more margin can use High at 78 FPS, but Ultra is confirmed playable by the measured data.

At 2560x1440, the most demanding playable preset is Medium, which averages exactly 60 FPS. The recorded minimum of 51 FPS indicates that the average is sustained across the benchmark, but individual frames can dip below the threshold. Low settings at 69 FPS provide a safer experience with 9 FPS of additional headroom, but Medium is the highest quality that meets the 60 FPS average requirement.

At 3840x2160, there is no playable preset. The verdict data lists no playable settings and no best settings for this resolution. The highest average is 37 FPS on Low, which falls well short of the 60 FPS threshold. Players should avoid 4K with this hardware combination for Doom, as even the lowest quality settings cannot achieve playable frame rates.
