Doom

The AMD Ryzen 5 5600GT paired with the Intel Arc B580 delivers a thoroughly playable Doom experience at 1080p and 1440p, but hits a wall at 2160p unless settings are dialed back. Measured data for this combination shows that the game’s demanding id Tech engine scales predictably with resolution and quality presets, with the GPU becoming the dominant factor at higher pixel counts.

Measured FPS Breakdown

At 1920x1080, this system is overwhelmingly fast. The Low preset produces an average of 181.9 FPS, which is nearly triple the 60 FPS playability threshold. Moving up through the presets, Medium delivers 161.9 FPS, High drops to 137 FPS, and even the most demanding Ultra preset holds an average of 112.4 FPS. Every setting at this resolution clears the 60 FPS bar by a wide margin, so players have complete freedom to prioritize visual fidelity or maximum refresh rates. The gap between Low and Ultra is 69.5 FPS, indicating that the preset scaling is substantial but that even the heaviest option leaves ample headroom.

At 2560x1440, the performance remains smooth but the impact of resolution scaling becomes clear. Low averages 118.3 FPS, Medium hits 105.8 FPS, and High settles at 88.1 FPS. The Ultra preset, which at 1080p was still comfortably above 100 FPS, drops to an average of 70.1 FPS at 1440p. That is still playable, but it demonstrates that the transition from 1080p to 1440p costs roughly 37 FPS on Ultra, a 33% reduction. The drop from High to Ultra at this resolution is 18 FPS, which is a larger step than the 12.5 FPS difference between Medium and High. This suggests that Ultra is particularly demanding on the Arc B580’s fill rate and memory bandwidth.

At 3840x2160, the system starts to struggle outside of the lowest preset. Low averages 64.4 FPS, barely clearing the 60 FPS threshold. Medium falls to 54 FPS, High to 47 FPS, and Ultra to 37.9 FPS. The scaling from Low to Ultra at 4K removes 26.5 FPS, and none of the higher presets reach playable territory. The data indicates that 4K is only viable with significant visual compromises, and even then, the margin above 60 FPS is just 4.4 FPS, leaving little room for frame-time spikes.

Across all resolutions, the pattern is consistent: the preset ladder from Low to Ultra costs roughly 38-40% of the average FPS, with the largest single drop occurring between High and Ultra at every resolution. The performance delta between 1080p and 1440p is roughly 25-30% depending on preset, while the jump from 1440p to 2160p costs between 40-50% of the average frame rate, underscoring the GPU’s bandwidth constraints at 4K.

Similar Performance Alternatives

The nearest rivals for this CPU and GPU combo provide useful context for what other hardware would behave similarly.

For the AMD Ryzen 5 5600GT, the closest alternatives in synthetic benchmark scores are all within a fraction of a percent. The Intel Core i5-12490F scores 20802, which is just 0.3% below the Ryzen’s 20733 average benchmark score. The Intel Xeon 6325P and Intel Core Ultra 5 125U both score 20821 and 20826 respectively, each trailing by 0.4%. The AMD EPYC 7J13 scores 20845, also 0.5% behind. In practical terms, all four of these processors would deliver near-identical frame rates in Doom, meaning that swapping the 5600GT for any of these parts would produce no measurable difference in the FPS figures listed above. The CPU sits at the 74th percentile among all tested CPUs, confirming that it is a solid mid-pack performer that will not bottleneck the Arc B580 in this title.

Q: How much performance is lost when moving from 1080p to 1440p?

A: The reduction depends on the preset. On Low, the drop is from 181.9 FPS to 118.3 FPS, a loss of 63.6 FPS. On Ultra, the drop is from 112.4 FPS to 70.1 FPS, a loss of 42.3 FPS. The percentage loss is larger at higher presets, indicating that the GPU becomes more stressed as resolution increases.

Q: Is the CPU or GPU more important for Doom at 1080p?

A: At 1920x1080, even the Ultra preset averages 112.4 FPS, which is far above the 60 FPS threshold. The CPU’s 6-core, 12-thread configuration with a 5523 score in the 3DMark 16-thread test is sufficient to feed the GPU without bottlenecking, as evidenced by the high frame rates across all presets. The GPU is the primary limiter at this resolution, but both components have ample headroom.

Q: Does the Arc B580 outperform the RTX 2080 in this game?

A: Yes, slightly. The Arc B580’s average benchmark score of 23021 is 0.6% higher than the RTX 2080’s 22895. In Doom, this translates to a negligible FPS difference, likely 1-2 frames at most, which would not be perceptible in gameplay.

Q: What is the worst-case performance scenario for this system?

A: The lowest recorded average FPS is 37.9 at 3840x2160 with the Ultra preset. This is the only configuration tested that falls below 40 FPS, and it is 22.1 FPS below the playability threshold. The system should avoid 4K Ultra entirely.

The Verdict

The verdict by resolution is clear. At 1920x1080, every preset is playable, with the Ultra preset averaging 112.4 FPS and the Low preset reaching 181.9 FPS. This system has more than enough power for high-refresh-rate monitors at 1080p. At 2560x1440, all four presets also clear 60 FPS, with Ultra at 70.1 FPS being the most demanding option that remains smooth. The system is well-suited for 1440p gaming across the full quality range. At 3840x2160, only the Low preset is playable, averaging 64.4 FPS. The Medium, High, and Ultra presets all fall short of 60 FPS, with averages of 54, 47, and 37.9 FPS respectively.

For a player prioritizing frame rate, the 1440p Ultra setting at 70.1 FPS offers the best balance of visual fidelity and smoothness. For those with 1080p displays, the Ultra preset at 112.4 FPS is the obvious choice, delivering near-double the required performance. The 4K experience is possible but requires dropping to Low, which sacrifices most graphical features for a modest 4.4 FPS margin above the threshold. This system is not recommended for 4K gaming at higher presets, as the data shows a steep performance cliff beyond Low settings.

CPU and GPU Roles

The division of labor between the Ryzen 5 5600GT and the Arc B580 changes significantly as resolution rises. At 1920x1080, the CPU has enough headroom to keep the GPU fully utilized, as evidenced by the 181.9 FPS on Low and 112.4 FPS on Ultra. The CPU’s single-thread score of 913 in 3DMark and 2438 in Cinebench R23 indicates strong per-core performance, which is critical for Doom’s engine that relies heavily on a few main threads. The GPU is the limiting factor at this resolution, but neither component is stressed to its maximum.

At 2560x1440, the GPU begins to take on a larger role. The drop from 1080p to 1440p costs between 42.3 and 63.6 FPS depending on preset, which is a direct result of the increased pixel count. The CPU’s frame delivery remains sufficient, as the lowest 1440p average (70.1 FPS on Ultra) is still well above the 60 FPS threshold. The scaling between Low and Ultra at 1440p is 48.2 FPS, slightly larger than the 69.5 FPS gap at 1080p, which suggests that the GPU is becoming the bottleneck as resolution increases.

At 3840x2160, the GPU is overwhelmingly dominant. The CPU has no difficulty keeping up, as even the slowest 4K preset (37.9 FPS on Ultra) is far below the CPU’s capable frame rate. The performance collapse at 4K is entirely attributable to the Arc B580’s 192-bit memory bus and 456.0 GB/s bandwidth, which struggles with the fourfold increase in pixel count from 1080p. The CPU’s role at 4K is to simply maintain frame pacing, which it does without issue. For players seeking higher 4K performance, the GPU would need to be upgraded, while the CPU could remain unchanged.

Best Settings per Resolution

At 3840x2160, the only preset that stays at or above 60 FPS is Low, with an average of 64.4 FPS. This is the maximum quality option that remains playable at 4K, and it barely clears the threshold. Any preset above Low, including Medium at 54 FPS, falls short of playable performance.

At 2560x1440, the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 70.1 FPS. This provides a 10.1 FPS cushion over the playability threshold, making it a safe choice for sustained gameplay. The High preset at 88.1 FPS offers more margin, but Ultra is the best visual option that still maintains smooth motion.

At 1920x1080, the most demanding preset that stays at or above 60 FPS is also Ultra, with an average of 112.4 FPS. This gives a massive 52.4 FPS buffer over the threshold, ensuring that even intense combat scenes with many enemies and particle effects will not cause frame drops below playable levels. For players with 144Hz or higher refresh rate monitors, the High preset at 137 FPS or even Medium at 161.9 FPS would better utilize the display’s capabilities, but Ultra remains the highest quality setting that keeps the game fully playable.
