Doom

How This Combo Ranks

The AMD Ryzen 5 4600G paired with the Intel Arc B390 ranks 3300 out of 3712 tested combinations for Doom. That places this system in the bottom 11 percent of all combos, meaning the vast majority of hardware pairings deliver a smoother experience. The combination is technically functional, but it sits far down the leaderboard, and the data reflects a setup that struggles at higher demands.

The CPU itself holds a percentile rank of 71 among all processors, which indicates a mid-range part that is far from the weakest link. The GPU tells a different story: the Arc B390 sits at the 9th percentile among all GPUs, a very low position. When a system pairs a reasonably capable processor with a GPU that ranks near the bottom, the graphics card becomes the dominant constraint in most scenarios. The combo rank of 3300 out of 3712 makes this clear: this is not a balanced build for Doom, and the experience will be defined by what the GPU can manage rather than what the CPU can offer.

At 1920x1080, the combo manages playable frame rates across every preset, including Ultra at 64 FPS average. That is the only resolution where the full range of settings remains usable. At 2560x1440, only Low and Medium stay at or above 60 FPS, with Medium averaging exactly 60 FPS. At 3840x2160, no preset reaches the 60 FPS threshold, with the best average being 37 FPS on Low. The pattern is consistent: as resolution climbs, the GPU's limitations become more severe, and even the lowest settings cannot compensate at 4K.

The gap between the combo's rank and what the CPU alone can do highlights the imbalance. A processor at the 71st percentile paired with a GPU at the 9th percentile produces a result that is closer to the GPU's low standing than the CPU's respectable position. For Doom, the data shows a system that can handle 1080p gaming well, manages 1440p with reduced settings, and fails to deliver a smooth experience at 4K.

Similar Performance Alternatives

The database lists four CPUs that produce nearly identical average benchmark scores to the Ryzen 5 4600G. The closest is the AMD Ryzen 3 PRO 5355GE, with an average score of 17482, just 0.1 percent below the 4600G's 17507. The Intel Core 7 150U scores 17395, a 0.6 percent deficit. The AMD Ryzen 3 8300GE and Intel Core i3-14100T score 17614 and 17648 respectively, which are 0.6 and 0.8 percent higher than the 4600G. For Doom, swapping to any of these processors would produce virtually identical CPU-driven performance, since the differences are under one percent.

On the GPU side, the Arc B390's nearest rivals are all NVIDIA parts from much older generations. The GeForce GT 520MX scores 1463, just 1.3 percent lower than the Arc B390's 1482. The GeForce 800M scores 1460, a 1.5 percent gap. The GeForce GT 625 OEM and GeForce GT 710 score 1446 and 1443, which are 2.5 and 2.7 percent lower respectively. These deltas are small enough that in practical gaming terms, the Arc B390 behaves almost identically to these older discrete GPUs. A user moving from a GT 710 to the Arc B390 would see negligible improvement in Doom, since the benchmark scores are within three percent of each other.

What this means for the combo is that the entire system's gaming performance in Doom is governed by a GPU that sits in the same performance class as decade-old entry-level cards. The CPU alternatives would not change the outcome, since none of them move the needle by more than a fraction of a percent. The GPU alternatives would also not change the experience, since they all cluster within a three percent band. This combo is effectively locked into its performance tier, and no nearby hardware swap would meaningfully alter the frame rates in Doom.

CPU and GPU Roles

The measured FPS data across resolutions reveals a system where the GPU is the decisive component at every setting. Consider the progression from 1920x1080 to 2560x1440 to 3840x2160 at the same preset. On Low settings, the average frame rate drops from 107 FPS at 1080p to 69 FPS at 1440p, then to 37 FPS at 4K. That is a 65 percent reduction from 1080p to 4K on the same preset. On Medium, the averages go from 93 FPS to 60 FPS to 33 FPS, a 65 percent drop as well. On High, the numbers are 78 FPS, 51 FPS, and 28 FPS, again a 64 percent decline. On Ultra, the averages are 64 FPS, 41 FPS, and 22 FPS, a 66 percent reduction.

These consistent percentage drops across all presets indicate a purely resolution-bound bottleneck. If the CPU were the limiting factor, the frame rate would stay relatively flat as resolution increases, since the CPU would be saturated regardless of pixel count. Instead, every preset shows the same steep decline, which is the signature of a GPU that runs out of fill rate and shader throughput as pixel count climbs.

The CPU's role is secondary but not irrelevant. At 1080p Low, the combo hits 107 FPS, which is high enough that the processor can feed the GPU without holding it back. At 1080p Ultra, the average is 64 FPS, still above the playable threshold, and the CPU has enough single-thread performance to maintain that. The Ryzen 5 4600G's single-thread benchmark scores, such as 1919 in Cinebench R23 single-core, are respectable for a mid-range desktop part, and they support frame rates well above 60 in this game.

The verdict data confirms the GPU's dominance. At 3840x2160, the database lists no playable settings at all, meaning even Low falls short of 60 FPS. At 2560x1440, Low and Medium are playable, but Medium only reaches exactly 60 FPS. At 1920x1080, all four presets are playable, with Ultra at 64 FPS. If the CPU were the bottleneck, the 4K results would not be so uniformly poor across all presets; the GPU is clearly the wall that the system hits.

For users of this combo, the practical takeaway is that lowering resolution is the only lever that meaningfully improves performance. Changing presets at the same resolution produces modest shifts, for example from 28 FPS at 4K High to 37 FPS at 4K Low, but moving from 4K to 1440p more than doubles the frame rate on the same preset. The CPU has headroom to spare, while the GPU is operating at its absolute limit.

The Ryzen 3 PRO 5355GE, Ryzen 3 8300GE, Core 7 150U, and Core i3-14100T would produce nearly identical results. Since the GPU is the bottleneck in this game, a CPU swap would not meaningfully change frame rates.

Q: What is the playable threshold and how does this combo fare against it?

A: The playable threshold is 60 FPS. This combo meets that threshold at 1080p across all presets and at 1440p on Low and Medium. It fails to meet the threshold at 4K on any preset, and it also fails at 1440p on High and Ultra.

Measured FPS Breakdown

The measured frame rates come directly from the database for this specific CPU and GPU combination.

At 1920x1080, the combo delivers its strongest results. Low settings average 107 FPS, with no minimum or maximum recorded. Medium averages 93 FPS, with a minimum of 79 FPS and a maximum of 107 FPS. High averages 78 FPS, and Ultra averages 64 FPS. The spread from Low to Ultra is 43 FPS, showing that the GPU can handle even the heaviest preset at this resolution while staying above 60 FPS.

At 2560x1440, the numbers drop noticeably. Low averages 69 FPS, which is still playable. Medium averages exactly 60 FPS, with a minimum of 51 FPS and a maximum of 69 FPS. High falls to 51 FPS, and Ultra drops to 41 FPS. The gap between Low and Ultra is 28 FPS, and the step from Medium to High is a 9 FPS loss, which pushes the experience below the playable threshold.

At 3840x2160, the combo struggles across the board. Low averages 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. Even the best case, Low at 37 FPS, is far below the 60 FPS target. The delta between Low and Ultra is 15 FPS, and no setting comes close to playability.

The minimum and maximum values recorded for Medium at each resolution provide useful context. At 1080p Medium, the range is 79 to 107 FPS, which means the frame rate never dips below 79 FPS. At 1440p Medium, the range is 51 to 69 FPS, so the low end falls below 60 even though the average hits exactly 60. At 4K Medium, the range is 28 to 37 FPS, with the entire range well below playable. These figures show that even at the same preset, higher resolutions introduce frame time variance that can push momentary dips below the average.

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 highest visual quality setting available in the game, and the combo manages to keep it playable at this resolution. Since Ultra is the top preset, there is no higher setting to consider, and the 64 FPS average provides a small margin above the 60 FPS threshold.

At 2560x1440, the best setting that meets the playable threshold is Medium, averaging exactly 60 FPS. Low also works at 69 FPS, but Medium offers better visual fidelity while still delivering the required frame rate. High and Ultra are not viable, with averages of 51 FPS and 41 FPS respectively. Users who prioritize smoothness over visuals could choose Low for a 9 FPS advantage, but Medium is the highest quality option that remains playable.

At 3840x2160, no preset reaches 60 FPS. The database lists no playable settings for this resolution. The closest is Low at 37 FPS, which is still 23 FPS short of the threshold. Medium, High, and Ultra are progressively worse, with averages of 33, 28, and 22 FPS. For this resolution, the combo is not a viable option for Doom, and users would need to drop to 1440p or lower to get a playable experience.

The data suggests that 1080p is the sweet spot for this hardware. At that resolution, the combo can run the game at its highest preset with a comfortable margin above 60 FPS. At 1440p, users must compromise on visual quality to maintain playability. At 4K, the hardware simply cannot keep up, and the experience would be marked by frequent frame rate drops and a general lack of responsiveness. For anyone considering this combo for Doom, the measured results indicate that 1080p Ultra is the recommended configuration, with 1440p Medium as a secondary option for those who need a higher resolution.
