Doom

Measured FPS Breakdown

At 3840x2160, the AMD Ryzen 7 9800X3D and Intel Arc B390 combination delivers playable frame rates at no settings tier. The recorded data shows a peak average of 37 FPS at Low settings, which falls well short of the 60 FPS threshold. Medium settings produce an average of 33 FPS with a minimum of 28 FPS and a maximum of 37 FPS. High settings yield 28 FPS on average, and Ultra settings drop to 22 FPS. The gap between Low and Ultra at this resolution is 15 FPS, indicating that the graphics workload scales steeply with preset changes.

Moving to 2560x1440, the combo crosses the 60 FPS line at two settings levels. Low settings record an average of 69 FPS. Medium settings hit exactly 60 FPS on average, with the frame rate ranging from 51 FPS at the low end to 69 FPS at the high end. High settings fall to 51 FPS average, and Ultra settings produce 41 FPS average. The spread from Low to Ultra is 28 FPS, a wider relative gap than observed at 4K, which suggests the GPU has more headroom at this resolution but still becomes the limiting factor under heavier loads.

At 1920x1080, every settings tier clears the 60 FPS threshold. Low settings average 107 FPS. Medium settings average 93 FPS, with a minimum of 79 FPS and a maximum of 107 FPS. High settings average 78 FPS. Ultra settings average 64 FPS, which remains above the 60 FPS playability line but with less margin than the lower presets. The difference between Low and Ultra at 1080p is 43 FPS, demonstrating that the Arc B390's performance scales substantially with preset selection even at the least demanding resolution.

The data indicates that the 3840x2160 Medium run is the only configuration in the entire dataset that includes explicit minimum and maximum values. All other entries lack those fields, so the analysis of frame pacing variability is limited to that single point. The 2560x1440 Medium run also includes min and max values, showing a 18 FPS swing between its floor and ceiling.

How This Combo Ranks

Within the database's collection of tested combinations for Doom, this pairing of the AMD Ryzen 7 9800X3D and Intel Arc B390 ranks 3300 out of 3712 total combos. That places it in the lower 11 percent of tested configurations, a position driven almost entirely by the GPU's modest compute capabilities rather than the CPU's strength.

The ranking reflects the aggregate performance across all measured resolutions and settings. The CPU itself sits in the 87th percentile compared to all processors in the database, while the GPU lands in the 9th percentile compared to all graphics cards. This extreme imbalance explains why the combo rank is so low: the processor is capable of feeding a far more powerful graphics solution, but the Arc B390 cannot translate that CPU headroom into high frame rates at demanding resolutions.

At 1080p, the combo manages to stay competitive because the CPU's strong single-thread and multi-thread scores help maintain frame delivery even when the GPU is the bottleneck. At 4K, however, the GPU's limitations dominate, and the rank reflects that steep drop-off. The 87th percentile CPU ranking and 9th percentile GPU ranking combine to produce a configuration that is CPU-heavy in character but GPU-limited in practice.

Similar Performance Alternatives

The nearest rivals for the AMD Ryzen 7 9800X3D, based on average benchmark scores, are all processors with similar aggregate performance. The AMD Ryzen 7 PRO 8840HS scores 39603, which is 0.4 percent lower than the 9800X3D's average of 39768. The AMD Ryzen AI 9 365 scores 40048, putting it 0.7 percent higher. The AMD Ryzen AI 7 450 scores 39485, 0.7 percent lower. The AMD Ryzen 7 7700 scores 40081, 0.8 percent higher. Any of these CPUs would behave similarly in a system paired with the Arc B390, since the GPU would remain the primary constraint in most gaming scenarios.

For the Intel Arc B390, the nearest rivals are all NVIDIA parts with comparable benchmark averages. The GeForce GT 520MX scores 1463, which is 1.3 percent lower than the Arc B390's 1482. The GeForce 800M scores 1460, 1.5 percent lower. The GeForce GT 625 OEM scores 1446, 2.5 percent lower. The GeForce GT 710 scores 1443, 2.7 percent lower. These delta values are small, meaning a system with any of these GPUs paired with a high-end CPU would produce frame rates very close to what the Arc B390 delivers in Doom.

The practical implication is that swapping the 9800X3D for a mid-range Ryzen part would not meaningfully change Doom's performance, because the GPU sits so far below the CPU's capability curve. Conversely, replacing the Arc B390 with a similarly scored GPU would preserve nearly identical frame rates, assuming the rest of the system remains unchanged.

The Verdict

The recorded data answers the question directly: this PC can run Doom, but only at specific resolutions and settings. At 1920x1080, all four settings tiers are playable, with Ultra producing 64 FPS on average. That is the highest quality preset that clears the 60 FPS threshold at this resolution.

At 2560x1440, the playable settings are Low and Medium. Medium is the best option, delivering exactly 60 FPS on average. High and Ultra fall below the threshold, with 51 FPS and 41 FPS respectively.

At 3840x2160, no settings tier reaches 60 FPS. The best result is Low at 37 FPS, which is smooth but not playable by the database's 60 FPS standard. Ultra at 22 FPS is the weakest showing.

The verdict is therefore resolution-dependent. A 1080p display with Ultra settings is the strongest configuration this combo can manage. A 1440p display requires dropping to Medium settings to maintain 60 FPS. A 4K display cannot sustain a playable frame rate at any preset.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 64 FPS. This is the highest quality option available for this resolution and provides a comfortable margin above the playability line.

At 2560x1440, the best settings are Medium, which average exactly 60 FPS. Low settings average 69 FPS, but Medium offers noticeably higher visual quality while still meeting the threshold. The minimum of 51 FPS at Medium means there will be occasional dips below 60 FPS, but the average holds the line.

At 3840x2160, there is no settings tier that reaches 60 FPS. Low settings at 37 FPS are the highest average available, but the database does not classify any preset as playable at this resolution. Users targeting 4K would need to consider a different GPU to meet the threshold.

CPU and GPU Roles

The data shows a clear division of labor between the AMD Ryzen 7 9800X3D and the Intel Arc B390 across resolutions. At 1920x1080, the CPU's strong single-thread performance (a 3dmark single-thread score of 1212 and a Cinebench R23 single-core score of 2080) helps sustain high frame rates even at Ultra settings, where the average remains 64 FPS. The GPU still does most of the rendering work, but the CPU is not leaving performance on the table.

At 2560x1440, the GPU begins to dominate. The drop from Low at 69 FPS to High at 51 FPS is a 18 FPS swing, while the CPU's workload remains relatively constant. This indicates that the Arc B390's shading units and texture units are the primary constraint as resolution increases. The GPU's 1536 shading units and 48 texture mapping units are simply insufficient for heavier presets at this resolution.

At 3840x2160, the GPU is almost entirely the limiting factor. The difference between Low at 37 FPS and Ultra at 22 FPS is just 15 FPS, which is a smaller absolute gap than at lower resolutions. This compression of frame rates suggests that the GPU is saturated even at Low settings, and the CPU's 8 cores and 16 threads have little influence on the outcome. The 9800X3D's high L3 cache of 96 MB and fast Zen 5 architecture provide ample headroom, but that headroom goes unused when the GPU cannot push more frames.

The scaling between presets reinforces this interpretation. At 1080p, moving from Low to Ultra costs 43 FPS. At 1440p, the same move costs 28 FPS. At 4K, it costs only 15 FPS. As resolution climbs, the GPU becomes more fully utilized at every preset, and the CPU's role diminishes accordingly. For users seeking better performance at 1440p or 4K, upgrading the GPU would yield far larger gains than upgrading the CPU, which already ranks in the 87th percentile of all processors in the database.
