Doom

The AMD Ryzen 9 7900X and Intel Arc B390 combination presents a very specific performance profile for Doom. The data shows a system that is heavily constrained by the graphics processor, particularly at higher resolutions. The benchmark results are clear: this combo is only viable for smooth gameplay at 1080p, with 1440p requiring a drop to medium settings, and 4K being entirely out of reach.

Measured FPS Breakdown

The recorded data for Doom shows a consistent pattern across all resolutions, where the average frame rate decreases as the graphical preset becomes more demanding. The measured FPS values are as follows:

At 3840x2160, the performance is below the playable threshold of 60 FPS at every setting. With Low settings, the average FPS is 37. Moving to Medium settings, the average drops to 33 FPS, with a recorded minimum of 28 FPS and a maximum of 37 FPS. High settings yield an average of 28 FPS, and Ultra settings bring the average down to 22 FPS. None of these averages come close to the 60 FPS target.

At 2560x1440, the situation improves but remains marginal. Low settings achieve an average of 69 FPS, which clears the 60 FPS threshold. Medium settings hit exactly 60 FPS on average, with the minimum recorded at 51 FPS and the maximum at 69 FPS. High settings drop to an average of 51 FPS, and Ultra settings average 41 FPS. The data indicates that only Low and Medium presets are playable at this resolution.

At 1920x1080, the combination finally shows its potential. Low settings deliver an average of 107 FPS. Medium settings average 93 FPS, with a minimum of 79 FPS and a maximum of 107 FPS. High settings produce an average of 78 FPS. Ultra settings, the most demanding preset tested, still manage to hold an average of 64 FPS. This is the only resolution where all four presets are above the 60 FPS threshold.

Best Settings per Resolution

Based on the recorded data, the best settings are defined as the most demanding preset that maintains an average of at least 60 FPS.

For 3840x2160, there is no qualifying preset. The highest average FPS recorded at this resolution is 37 FPS on Low settings, which is well below the 60 FPS target. The database indicates no playable settings at this resolution.

For 2560x1440, the best settings are Medium. This preset achieves an average of 60 FPS, which exactly meets the playable threshold. While Low settings also clear the bar with an average of 69 FPS, Medium is the more demanding option that still provides a playable experience.

For 1920x1080, the best settings are Ultra. This preset averages 64 FPS, which is above the 60 FPS threshold. This is notable because it means the system can run the game at its highest graphical quality at this resolution while maintaining a smooth frame rate.

Similar Performance Alternatives

The nearest rivals in the database provide a context for understanding how this specific CPU and GPU pairing performs relative to other components.

For the CPU, the AMD Ryzen 9 7900X has an average benchmark score of 53288. The closest alternatives are the AMD EPYC 7313P, with an average score of 53206 and a delta of 0.2%, and the Intel Xeon Phi 7290, with an average score of 53469 and a delta of -0.3%. The Intel Xeon 634 scores 52974 with a delta of 0.6%, and the Intel Core i7-14700F scores 53620 with a delta of -0.6%. These deltas are all within one percent, indicating that any of these CPUs would deliver nearly identical processor-bound performance in Doom. The choice between them would not meaningfully alter the frame rates recorded in this analysis.

For the GPU, the Intel Arc B390 has an average benchmark score of 1482. This places it in the 9th percentile of all GPUs. Its nearest rivals are all NVIDIA parts with very similar scores. The NVIDIA GeForce GT 520MX scores 1463 with a delta of 1.3%, the NVIDIA GeForce 800M scores 1460 with a delta of 1.5%, the NVIDIA GeForce GT 625 OEM scores 1446 with a delta of 2.5%, and the NVIDIA GeForce GT 710 scores 1443 with a delta of 2.7%. These are all low-end graphics solutions, and the data suggests that swapping the Arc B390 for any of these would produce a very similar performance envelope. The frame rates would be within a few percentage points of each other, reinforcing the conclusion that the GPU is the primary bottleneck in this system.

The Verdict

The question of whether this PC can run Doom depends entirely on the target resolution and settings. The data from the database provides a definitive answer for each resolution.

At 1920x1080, the system is fully capable. The verdict indicates that all four presets, High, Low, Medium, and Ultra, are playable. The Ultra preset averages 64 FPS, which clears the 60 FPS threshold with a small margin. This is the only resolution where the user can enable the highest settings without sacrificing smoothness.

At 2560x1440, the system is partially capable. The playable settings are Low and Medium. The Medium preset is the best option, averaging exactly 60 FPS. However, the minimum FPS of 51 suggests that there may be moments of perceptible stutter, even if the average is acceptable. High and Ultra presets are not playable at this resolution.

At 3840x2160, the system is not capable of running the game at a playable frame rate. No settings are listed as playable. The best average FPS is 37 on Low, which is far below the 60 FPS target. The system should not be considered for 4K gaming with this title.

In summary, this combination can run Doom, but only at 1080p with all settings, or at 1440p with reduced settings. For the most demanding visual experience, 1080p with Ultra is the intended use case.

How This Combo Ranks

The database places this specific combination of the AMD Ryzen 9 7900X and Intel Arc B390 at rank 3300 out of 3712 total tested combos for Doom. This ranking puts it in the lower 11th percentile of all systems tested for this game.

This low ranking is consistent with the GPU's performance class. The Intel Arc B390 sits in the 9th percentile of all GPUs, and its nearest rivals are all entry-level NVIDIA parts. The CPU, on the other hand, is in the 91st percentile of all CPUs. The massive disparity between the CPU's high percentile and the GPU's low percentile means the system's overall rank is dragged down by the graphics component.

The rank of 3300 out of 3712 indicates that a large majority of other hardware combinations will deliver higher frame rates in Doom. While the system is playable at 1080p, it is not competitive with even mid-range alternatives in the database. Users considering this combination should understand that its overall standing is low due to the graphics bottleneck.

CPU and GPU Roles

The data reveals a clear division of labor between the CPU and GPU for this game. By examining the scaling of frame rates across resolutions and presets, it is possible to identify which component is the limiting factor.

The Intel Arc B390 is the dominant constraint. The evidence for this is the dramatic drop in performance as resolution increases. At 1080p on Low settings, the average FPS is 107. At 1440p on Low settings, it drops to 69. At 4K on Low settings, it falls to 37. This steep decline is typical of a GPU-bound scenario, where the graphics processor cannot keep up with the increasing pixel count. The GPU's benchmark percentile of 9th, and its nearest rivals being the GT 520MX and GT 710, further confirms that it is a very low-end part.

The CPU's role is less critical. The AMD Ryzen 9 7900X is a high-end processor with a 91st percentile ranking. Its performance is sufficient to feed the GPU at all tested settings, as the frame rates are consistently limited by the GPU rather than the CPU. This is evident from the fact that increasing the graphical preset at a fixed resolution consistently reduces the average FPS. For example, at 1080p, moving from Low to Ultra reduces the average from 107 to 64 FPS. If the CPU were the bottleneck, this change in settings would have a smaller impact on frame rates.

The scaling between presets also points to the GPU as the key factor. At 1080p, the difference between Low and Ultra is 43 FPS. At 1440p, the same comparison shows a difference of 28 FPS (69 to 41). At 4K, the difference is 15 FPS (37 to 22). As resolution increases, the absolute difference in FPS between presets shrinks, but the percentage impact remains significant. This is because the GPU is already struggling to fill pixels at higher resolutions, so additional graphical effects have a relatively smaller absolute effect on frame time.

Ultimately, the GPU is the sole performance limiter for this game. The CPU has ample headroom and will not be a bottleneck at any resolution or preset. For users seeking higher frame rates, replacing the Intel Arc B390 with a more capable GPU would yield a substantial improvement, while upgrading the CPU would provide no measurable benefit in this title.
