CPU and GPU Roles

The recorded data reveals a system where the GPU is the dominant constraint at every resolution. The Intel Arc B390 sits in the 9th percentile among all GPUs in the database, with a Steel Nomad DX12 score of 1482. Its nearest rivals are all legacy NVIDIA parts: the GT 520MX (1463), GeForce 800M (1460), GT 625 OEM (1446), and GT 710 (1443). The GPU's performance class explains why frame rates collapse as resolution increases.

At 1920x1080, the GPU still has enough bandwidth to push respectable numbers. Low settings average 107 FPS, and even Ultra clears 60 FPS with a 64 FPS average. The scaling from Medium to Ultra at 1080p shows a drop from 93 to 64 FPS, a 31% reduction in average frame rate. This suggests the GPU is the limiting factor: raising visual quality directly cuts into throughput.

At 2560x1440, the picture changes. Low settings drop to 69 FPS, Medium to 60 FPS, and High to 51 FPS. The gap between Low and Medium is 9 FPS, while Medium to High costs another 9 FPS. The GPU's limited shading resources (1536 shading units, 48 TMUs, 24 ROPs) are being saturated as pixel count rises. The CPU's role shrinks further: the Ryzen 7 5800XT's 8 cores and 16 threads, with a boost clock of 4.80 GHz, are far beyond what this workload demands.

At 3840x2160, the GPU is overwhelmed. Every preset averages below 40 FPS: Low at 37, Medium at 33, High at 28, Ultra at 22. The step from 1080p Low (107 FPS) to 4K Low (37 FPS) represents a 65% loss in average frame rate. The CPU contributes almost nothing to this bottleneck. Its 3DMark 16-thread score of 7683 and single-thread score of 959 place it far above any requirement this game can impose.

The pattern is consistent: resolution scaling dominates all other variables. The gap between 1080p and 1440p at Low settings is 38 FPS (107 to 69), and the gap between 1440p and 4K at Low is 32 FPS (69 to 37). This is a GPU-bound scenario at every step. The Ryzen 7 5800XT, with its 32 MB shared L3 cache and dual-channel DDR4 memory bandwidth of 51.2 GB/s, is never the constraint.

The verdict from the data: for this game, the CPU matters only insofar as it avoids becoming a bottleneck, which it does easily. The GPU dictates playability at each resolution, and the Arc B390's 7.680 TFLOPS FP32 throughput is simply insufficient for higher-resolution gaming.

Measured FPS Breakdown

3840x2160 (4K)

The database records no playable settings at this resolution. Ultra settings produce a 22 FPS average. High settings reach 28 FPS. Medium settings average 33 FPS, with a minimum of 28 FPS and a maximum of 37 FPS. Low settings are the fastest at 37 FPS. Every preset falls far below the 60 FPS playable threshold. Even the best-case Medium maximum of 37 FPS is only 62% of the target.

2560x1440 (1440p)

Ultra settings average 41 FPS, below the playable threshold. High settings reach 51 FPS. Medium settings hit exactly 60 FPS on average, with a minimum of 51 FPS and a maximum of 69 FPS. Low settings average 69 FPS. The data shows that Medium is the highest preset that maintains a 60 FPS average. The min/max spread on Medium spans 18 FPS, indicating some frame pacing variability, but the average holds.

1920x1080 (1080p)

Ultra settings deliver a 64 FPS average, clearing the 60 FPS threshold. High settings average 78 FPS. Medium settings hit 93 FPS, with a minimum of 79 FPS and a maximum of 107 FPS. Low settings reach 107 FPS. All four presets are playable. The jump from Ultra to High is 14 FPS, from High to Medium is 15 FPS, and from Medium to Low is another 14 FPS. The scaling is nearly linear, reflecting the GPU's compute limits rather than any CPU constraint.

The recorded numbers show a consistent pattern: the Arc B390 can handle 1080p at any preset, 1440p only at Low or Medium, and 4K at no preset. The minimum FPS values, where recorded, confirm that frame drops are manageable at 1440p Medium (51 FPS min) and 1080p Medium (79 FPS min), but the absence of min/max data for most entries means the database only guarantees average performance.

The Verdict

Can this PC run Doom? The answer depends entirely on the target resolution.

At 3840x2160, the verdict is clear: no. The verdictByResolution field lists no playable settings. The highest average is 37 FPS on Low, which is 23 FPS short of the 60 FPS playable threshold. Even the most favorable recorded frame rate (37 FPS max on Medium) does not approach playability. Users at 4K must either lower the resolution or accept a sub-60 FPS experience.

At 2560x1440, the system is partially playable. The verdict lists Low and Medium as playable settings. Medium averages exactly 60 FPS, meeting the threshold. Low averages 69 FPS, providing more headroom. High and Ultra are not playable: High averages 51 FPS, Ultra averages 41 FPS. The recommendation is Medium as the best playable preset, but users who prefer stable minimums may opt for Low.

At 1920x1080, the system is fully playable. The verdict lists all four presets: High, Low, Medium, and Ultra. Ultra averages 64 FPS, clearing the threshold by 4 FPS. High averages 78 FPS, Medium 93 FPS, Low 107 FPS. This is the only resolution where every preset is viable.

To summarize: this combination runs Doom comfortably at 1080p, acceptably at 1440p with settings compromises, and not at all at 4K. The GPU's 9th percentile ranking among all tested GPUs explains the ceiling. The Ryzen 7 5800XT, in the 81st CPU percentile, is not the limiting factor.

Best Settings per Resolution

3840x2160: No playable preset exists. The database's verdictByResolution field returns null for best settings and average FPS at this resolution. The highest average, 37 FPS on Low, is insufficient. Users should not target 4K with this hardware.

2560x1440: Medium is the most demanding preset that stays at or above 60 FPS. The recorded average is exactly 60 FPS, with a minimum of 51 FPS and a maximum of 69 FPS. This is the recommended choice for 1440p. Low settings (69 FPS) offer more margin, but Medium provides the best visual quality while meeting the playable threshold.

1920x1080: Ultra is the most demanding preset that stays at or above 60 FPS. The recorded average is 64 FPS. This is the recommended choice for 1080p. High (78 FPS), Medium (93 FPS), and Low (107 FPS) are all viable alternatives, but Ultra delivers the maximum visual quality within the playable envelope.

The data suggests a straightforward settings guide: at 1080p, max everything out; at 1440p, choose Medium and accept 60 FPS; at 4K, do not attempt it.

How This Combo Ranks

The AMD Ryzen 7 5800XT and Intel Arc B390 combination ranks 3300 out of 3712 tested combos in Doom. That places it in the bottom 11% of all configurations in the database. The rank reflects the GPU's severe performance limitation: the Arc B390 sits at the 9th percentile among all GPUs, and its nearest rivals are all low-end legacy parts.

The CPU, by contrast, is a strong performer. The Ryzen 7 5800XT ranks in the 81st percentile among all CPUs, with an average benchmark score of 29879. Its nearest rivals include the AMD Ryzen 7 7840H (29868, 0% delta), Ryzen 7 8845HS (29955, -0.3% delta), Ryzen 7 7840HS (29955, -0.3% delta), and Ryzen 5 9600X (29713, 0.6% delta). The 5800XT is effectively tied with these parts, confirming it is not the source of the low combo rank.

The GPU's benchmark profile is stark: a single recorded 3DMark Steel Nomad DX12 score of 1482, with the nearest rival being the GT 520MX at 1463. The Arc B390 leads that part by 1.3%, the GeForce 800M by 1.5%, the GT 625 OEM by 2.5%, and the GT 710 by 2.7%. These are all sub-1500 scores, indicating that the Arc B390 is competing in a performance tier that is fundamentally unsuited for 4K gaming.

The combo's rank of 3300 out of 3712 means 412 other combinations perform worse in Doom. Those worse-performing combos almost certainly pair the Arc B390 with weaker CPUs, or use even lower-tier GPUs. The 5800XT's inclusion in this system does not boost the ranking because the GPU caps the frame rate at every resolution. The measured FPS data confirms this: at 1080p Ultra, the system hits 64 FPS, which is exactly at the playable threshold. A stronger GPU would push that number far higher, but the CPU would still have ample headroom.

In summary, this combo is a case of a high-tier CPU wasted on a low-tier GPU. The Ryzen 7 5800XT is a top-quartile processor, while the Arc B390 is a bottom-decile graphics solution. The result is a system that plays Doom at 1080p with all settings maxed, at 1440p with Medium settings, and not at all at 4K. The rank reflects the GPU's ceiling, not the CPU's capability.
