Doom

The AMD Ryzen 5 7400F and Intel Arc B580 pairing delivers a compelling 1080p and 1440p experience in Doom, but the data reveals a clear performance ceiling as resolution climbs. The measured frame rates show a system that is well-balanced at lower resolutions but becomes progressively GPU-limited at 4K, where the gap between settings narrows dramatically. This analysis breaks down the measured FPS data to understand where the bottleneck lies and what the numbers imply for gameplay.

Resolution Scaling

The measured FPS data shows a predictable yet informative scaling pattern from 1080p to 4K. At 1080p with High settings, the combo produces 137 FPS, which drops to 88 FPS at 1440p and further to 48 FPS at 4K. This represents a 36% performance drop from 1080p to 1440p, and a further 45% drop from 1440p to 4K. The scaling is not linear, indicating that the GPU is becoming the primary limiting factor as pixel count increases.

Looking at the Low settings row, the trend is even more pronounced: 186 FPS at 1080p falls to 120 FPS at 1440p (a 35% reduction) and then to 65 FPS at 4K (a 46% reduction from 1440p). The consistency of these percentage drops across settings suggests the scaling behavior is resolution-driven rather than settings-driven. The GPU workload at 4K is so demanding that even dropping from High to Low only yields a 17 FPS improvement (from 48 to 65), whereas at 1080p the same settings change delivers a 49 FPS improvement (from 137 to 186).

This pattern strongly implies that at 1080p and 1440p, the CPU has enough headroom to feed the GPU adequately, but at 4K the Arc B580’s rendering capabilities are saturated. The fact that Ultra settings at 4K produce only 39 FPS, while Medium produces 57 FPS, shows that the GPU's compute units and memory bandwidth are stretched to their limits. The data suggests that players targeting 4K will need to make significant compromises, while those at 1440p can enjoy a smooth experience with High settings.

The 4K Medium row provides the only min/max FPS data in the entire set, showing a range of 48 to 65 FPS. This 17 FPS spread indicates frame time inconsistency at this resolution, likely due to the GPU struggling to maintain a steady workload. At 1440p Medium, the min/max range is 89 to 120 FPS, a 31 FPS spread, which is proportionally similar but at a much higher absolute level. This suggests that the frame pacing issues at 4K are not a unique anomaly but rather an amplification of the same bottleneck that exists at lower resolutions.

GPU Role

The Intel Arc B580’s specifications provide context for the measured results. With 12 GB of GDDR6 memory on a 192-bit bus delivering 456.0 GB/s of bandwidth, the GPU has ample memory capacity for Doom at all tested resolutions. The 2560 shading units, 160 TMUs, and 80 ROPs are the workhorses that determine raw fill rate and pixel throughput. The pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s are the theoretical ceilings that the measured FPS data can be compared against.

The base and boost clocks are both 2670 MHz, which is a relatively high operating frequency. This clock speed, combined with the 13.67 TFLOPS of FP32 performance, explains why the GPU can still deliver 48 FPS at 4K High settings. The FP16 performance of 27.34 TFLOPS (2:1 ratio) suggests the architecture is optimized for workloads that can utilize half-precision, though Doom’s rendering pipeline likely relies primarily on FP32.

The GPU’s benchmark scores place it in the 68th percentile of all GPUs, with an average benchmark score of 23021. Its nearest rivals include the AMD Radeon RX 580 2048SP (score 23061, -0.2% delta) and the NVIDIA GeForce RTX 2080 (score 22895, +0.6% delta). This positioning indicates that the Arc B580 is competitive with older high-end cards but sits below modern top-tier offerings. The RTX 3080 comparison is notable: the Arc B580 scores 0.7% lower (23172 vs 23021), yet the RTX 3080 would likely perform differently in Doom due to architectural differences not captured in these aggregate benchmarks.

The 12 GB VRAM capacity is never likely to be a limiting factor in Doom, as even at 4K Ultra the game’s texture requirements are well within this budget. The memory clock of 2375 MHz (19 Gbps effective) provides the bandwidth necessary to feed the 80 ROPs efficiently. The data suggests that the GPU’s compute capabilities, not its memory subsystem, are what constrain performance at higher resolutions.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Raphael. Its base clock of 3.70 GHz and boost clock of 4.70 GHz are respectable for a desktop part, and the 65W TDP indicates efficient power delivery. The 32 MB of shared L3 cache is significant for gaming workloads, as it reduces memory latency for frequently accessed data. The CPU’s memory support for DDR5 with dual-channel configuration and 83.2 GB/s bandwidth ensures the GPU is fed with data quickly.

The CPU’s benchmark scores show strong multi-core and single-core performance. The Cinebench R23 multi-core score of 21765 and single-core score of 3072 are indicative of a processor that can handle both heavily threaded and lightly threaded workloads. The PassMark single-thread score of 3689 further confirms this, as Doom is a game that benefits from strong single-core performance for game logic and physics.

The CPU sits in the 83rd percentile of all CPUs, with an average benchmark score of 32750. Its nearest rivals include the Intel Core i5-14600T (score 32707, +0.1% delta) and the Intel Core Ultra 7 155H (score 32697, +0.2% delta). These rivals are all within 0.3% of the Ryzen 5 7400F’s score, indicating that this is a tightly contested performance tier. The AMD Ryzen 7 PRO 6850H scores 0.2% higher (32812), showing that the 7400F is competitive with higher-tier mobile processors.

In Doom, the CPU’s 6 cores and 12 threads are sufficient to avoid becoming a bottleneck at 1080p and 1440p. The measured FPS at 1080p Low (186 FPS) is high enough that the CPU must be capable of issuing draw calls and processing game logic at a rate that supports such frame rates. The fact that 4K performance drops to 39-65 FPS regardless of settings suggests the GPU is the limiting component at that resolution, not the CPU.

Q: Is the CPU or GPU the bottleneck in this system?

A: At 1080p and 1440p, the system appears balanced, as FPS scales predictably with resolution. At 4K, the GPU becomes the clear bottleneck, as evidenced by the narrow FPS range between Low (65 FPS) and High (48 FPS) settings.

Q: Can this combo run Doom at 4K smoothly?

A: At 4K Medium, the measured average is 57 FPS with a min of 48 and max of 65. This is playable but not ideal for high refresh rate displays. For a consistently smooth 4K experience, users would need to accept lower settings or a lower resolution.

Q: How does the Arc B580 compare to its nearest GPU rivals?

A: The Arc B580’s average benchmark score of 23021 is 0.2% lower than the AMD Radeon RX 580 2048SP (23061) and 0.6% higher than the NVIDIA GeForce RTX 2080 (22895). It scores 0.7% lower than the RTX 3080 (23172).

Q: What settings preset provides the most balanced experience at 1440p?

A: High settings at 1440p deliver 88 FPS average, which is the best combination of visual quality and performance. Medium settings provide 105 FPS but with lower visual fidelity, while Ultra drops to 72 FPS.

Settings Recommendations

The measured data provides clear guidance for optimizing the experience across resolutions. At 1080p, all settings presets are playable, with Low achieving 186 FPS, Medium at 162 FPS, High at 137 FPS, and Ultra at 112 FPS. For players with high refresh rate monitors, Medium or High offers the best balance, as the difference between Low and Medium is only 24 FPS, while the jump from High to Ultra costs 25 FPS for marginal visual gains.

At 1440p, the recommendation shifts to High settings, which delivers 88 FPS. Medium provides 105 FPS but the visual quality reduction may not be worth the 17 FPS gain. Ultra at 72 FPS is still above 60 FPS but the 16 FPS drop from High is significant. Low at 120 FPS is excellent for competitive play but sacrifices too much visual fidelity for a single-player FPS experience.

At 4K, the data suggests Medium is the optimal choice, with 57 FPS average and a min/max range of 48-65 FPS. High settings drop to 48 FPS, which is below the 60 FPS threshold for smooth gameplay. Low settings at 65 FPS are the only way to exceed 60 FPS at 4K, but the visual compromise is substantial. Ultra at 39 FPS is not recommended for any playable experience.

The pattern across all resolutions is that Medium and High settings offer the best performance-to-quality ratios. Ultra settings consistently cost 20-25% of the FPS compared to High, while Low settings provide diminishing returns at higher resolutions where the GPU is already saturated.

Measured FPS Breakdown

At 3840x2160, the measured average FPS values are: Low at 65 FPS, Medium at 57 FPS (with min 48 and max 65), High at 48 FPS, and Ultra at 39 FPS. The 26 FPS spread between Low and Ultra represents a 40% performance range, which is substantial but smaller than at lower resolutions.

At 2560x1440, the results improve significantly: Low at 120 FPS, Medium at 105 FPS (with min 89 and max 120), High at 88 FPS, and Ultra at 72 FPS. The spread between Low and Ultra is 48 FPS, or 40% of the Low value. The min/max range at Medium shows a 31 FPS spread, indicating frame pacing variability.

At 1920x1080, the performance is highest: Low at 186 FPS, Medium at 162 FPS (with min 137 and max 186), High at 137 FPS, and Ultra at 112 FPS. The spread between Low and Ultra is 74 FPS, which is 40% of the Low value. This consistency in the 40% range across all resolutions is notable and suggests a uniform scaling behavior.

The Medium settings rows are the only ones with complete min/max data. At all three resolutions, the max FPS equals the Low settings average for that resolution, while the min FPS equals the High settings average. This pattern indicates that Medium settings are effectively a blend of Low and High performance, with the frame rate oscillating between the two extremes depending on scene complexity.

How This Combo Ranks

The AMD Ryzen 5 7400F + Intel Arc B580 combination ranks 2175 out of 2930 tested combos in Doom. This places it in the 74th percentile of all tested combinations, meaning roughly 26% of combos perform better. The rank is determined by aggregating all measured FPS data across resolutions and settings, providing a single composite score for comparison.

Given the CPU’s 83rd percentile ranking and the GPU’s 68th percentile ranking, the combo’s 74th percentile position is roughly in line with expectations. The CPU is a stronger component relative to its peers, while the GPU is slightly below average. This suggests the combo’s overall ranking is constrained by the GPU’s performance ceiling, particularly at higher resolutions.

The nearest CPU rivals all have nearly identical average benchmark scores (within 0.3%), so the choice of CPU is unlikely to dramatically alter the combo’s ranking. The GPU, however, has a wider performance spread among its rivals, with the RTX 3080 scoring 0.7% higher. This indicates that upgrading the GPU would likely yield a more significant improvement in Doom performance than upgrading the CPU.

The combo’s ranking of 2175 out of 2930 means it outperforms 755 other combinations. This is a solid mid-to-upper tier position, indicating that this pairing is well-suited for Doom at 1080p and 1440p, with acceptable performance at 4K with settings adjustments. The data supports the conclusion that this is a balanced system for the game, with the GPU being the primary upgrade path for those seeking higher frame rates at 4K.
