Doom

The AMD Ryzen 5 5600X paired with the Intel Arc B370 produces a highly constrained gaming experience in Doom, with benchmark results indicating that the integrated graphics solution is the definitive bottleneck at every tested configuration. The data shows a processor operating well within its capabilities while the GPU struggles to maintain playable frame rates, particularly at higher resolutions and quality settings.

Resolution Scaling

The measured frame rates reveal a stark and predictable scaling pattern as resolution increases, with the Arc B370’s limited fillrate and memory bandwidth becoming the dominant factor. At 1080p with Low settings, the combination achieves an average of 96 FPS, which drops to 62 FPS at 1440p and further to 34 FPS at 4K. This represents a 35% reduction in performance when moving from 1080p to 1440p, and a 65% reduction from 1080p to 4K, indicating that the GPU is being saturated by the increasing pixel count.

The scaling behavior becomes more telling when examining the High preset. The 1080p High setting yields 71 FPS, while 1440p High drops to 46 FPS, and 4K High falls to 25 FPS. The percentage losses are consistent with a GPU-bound scenario: 35% between 1080p and 1440p, and 65% between 1080p and 4K. This linear degradation pattern suggests that the Ryzen 5 5600X is not contributing to the frame rate drop, as a CPU bottleneck would typically show diminishing returns at higher resolutions where the GPU workload increases.

Further evidence of GPU limitation comes from the Ultra preset, which produces 58 FPS at 1080p, 37 FPS at 1440p, and 20 FPS at 4K. The 4K Ultra result of 20 FPS is effectively unplayable, while the 1080p Ultra result barely approaches the 60 FPS threshold. The delta between Low and Ultra at each resolution highlights the GPU’s inability to handle increased shading and texture work: at 1080p, the gap is 38 FPS (96 to 58), at 1440p it is 25 FPS (62 to 37), and at 4K it is 14 FPS (34 to 20). This narrowing gap at higher resolutions confirms that the GPU is the limiting component, as the relative cost of additional settings diminishes when pixel throughput becomes the primary constraint.

FAQ

Q: Is the Ryzen 5 5600X holding back the Arc B370 in Doom?

A: No. The data indicates the CPU is not the limiting factor. The Ryzen 5 5600X has a 75th percentile ranking among all CPUs and a passmark single-thread score of 3364, which is more than sufficient for Doom’s workload. The consistent frame rate drops across resolutions point entirely to the GPU.

Q: What is the best resolution for this combination?

A: 1080p is the only resolution where the combo approaches acceptable performance. The Low preset at 1080p delivers 96 FPS, and Medium delivers 84 FPS. At 1440p, even Low settings only reach 62 FPS, and at 4K, all settings fall below 34 FPS.

GPU Role

The Intel Arc B370 is an integrated graphics processor based on the Xe3-LPG architecture, built on Intel’s 3 nm process. Its specifications reveal why it struggles with Doom: the GPU has 1280 shading units, 40 texture mapping units, and 20 render output units, with a boost clock of 2400 MHz. The pixel rate is 48.00 GPixel/s and the texture rate is 96.00 GTexel/s, figures that are modest by discrete GPU standards.

The memory configuration is particularly problematic for a demanding title like Doom. The Arc B370 uses System Shared memory, meaning it relies on the host system’s DDR4 RAM rather than dedicated VRAM. The bandwidth is listed as System Dependent, which in this configuration is tied to the Ryzen 5 5600X’s dual-channel memory bus rated at 51.2 GB/s. This shared memory arrangement creates a bottleneck for texture streaming and framebuffer operations, especially at higher resolutions where memory pressure increases significantly.

The GPU’s 6.144 TFLOPS FP32 performance and 12.29 TFLOPS FP16 performance (2:1 ratio) are consistent with its 25 W TDP, which classifies it as a low-power IGP solution. The 3DMark Steel Nomad DX12 benchmark score of 1184 places the Arc B370 in the 5th percentile of all GPUs, indicating that it performs worse than 95% of tested graphics solutions. This percentile ranking is supported by its nearest rivals, which are all older, low-end mobile or entry-level desktop parts from the ATI and AMD Radeon HD era.

The relationship between the GPU’s clock speeds and Doom’s results is direct: the 2400 MHz boost clock is not sufficient to overcome the architectural and memory limitations. At 1080p Low, the GPU can sustain 96 FPS, but adding resolution or quality settings rapidly overwhelms its 20 ROPs and shared memory subsystem. The data suggests that the Arc B370 is designed for basic productivity and light gaming, not for a fast-paced FPS like Doom at high settings.

Settings Recommendations

Based on the measured frame rates, the only viable configuration for a smooth experience is 1080p with the Low preset, which delivers an average of 96 FPS. This is the only tested setting that provides a comfortable margin above the 60 FPS threshold typically required for responsive gameplay. The Medium preset at 1080p averages 84 FPS, which is still playable, but the jump to High drops the average to 71 FPS, and Ultra falls to 58 FPS, which may introduce noticeable stutter in intense combat scenes.

At 1440p, the situation is more constrained. The Low preset achieves 62 FPS, which is exactly at the playability threshold, but the Medium preset drops to 54 FPS with minimums of 46 FPS, indicating inconsistent frame pacing. The High and Ultra presets at 1440p produce 46 FPS and 37 FPS respectively, both of which are below acceptable standards for a first-person shooter. Given the data, 1440p Low is the only reasonable choice if resolution is a priority, but it offers no visual quality advantage over 1080p Medium.

At 4K, no setting is recommended. The best result is 34 FPS on Low, which is well below playable, and the Medium preset’s minimum of 25 FPS makes it unsuitable for action sequences. The measured data clearly indicates that this combination should be used at 1080p only. For users who prefer visual fidelity over frame rate, the High preset at 1080p (71 FPS) provides a balance, but the Ultra preset’s 58 FPS average is the maximum quality setting that remains marginally playable. The recommendation is to prioritize frame rate with Low or Medium at 1080p, as the GPU’s 5th percentile ranking does not support high-quality rendering without significant performance penalties.

How This Combo Ranks

The combination of the AMD Ryzen 5 5600X and Intel Arc B370 ranks 2696 out of 2930 tested combos in Doom, placing it in the bottom 8% of all configurations. This ranking reflects the severe GPU limitation, as the CPU is a high-performing part with a 75th percentile ranking among all processors. The disparity between the CPU’s capability and the GPU’s performance is stark: the Ryzen 5 5600X achieves a passmark multithread score of 21858 and a cinebench R23 multicore score of 11838, while the Arc B370’s 3DMark score of 1184 is near the bottom of the GPU hierarchy.

The combo’s rank is worse than what the CPU alone would suggest, indicating that the GPU is dragging down the overall experience. The Ryzen 5 5600X’s nearest CPU rivals, such as the AMD Ryzen 7 4800H (0.1% higher score) and the Intel Core i7-11700 (0.5% higher score), would likely perform identically in this configuration due to the GPU bottleneck. Similarly, the Arc B370’s nearest GPU rivals, the ATI Mobility Radeon HD 5570 and AMD Radeon HD 7650M, would produce similar frame rates in Doom when paired with a strong CPU.

This ranking of 2696 out of 2930 places the combo in the lowest percentile tiers of the database, alongside other pairings where a powerful processor is matched with an entry-level or integrated graphics solution. The data suggests that users seeking better Doom performance would need to upgrade the GPU significantly, as the CPU has ample headroom. The measured FPS results across all resolutions and settings support this conclusion, showing that no configuration with this GPU exceeds 96 FPS, which is a modest result for a 2016-era game running on a 2020-era CPU.

Measured FPS Breakdown

At 1920x1080, the measured results show a clear progression across quality presets. The Low preset delivers the highest average at 96 FPS, followed by Medium at 84 FPS with a minimum of 71 FPS and maximum of 96 FPS. The High preset averages 71 FPS, and the Ultra preset drops to 58 FPS. All 1080p results are within the playable range, though Ultra is borderline.

At 2560x1440, performance degrades significantly. The Low preset averages 62 FPS, which is the only 1440p result that approaches playability. The Medium preset averages 54 FPS with a minimum of 46 FPS and maximum of 62 FPS, showing significant variance. The High preset averages 46 FPS, and the Ultra preset averages 37 FPS. None of these 1440p results provide a consistently smooth experience.

At 3840x2160, the results are uniformly poor. The Low preset averages 34 FPS, the Medium preset averages 29 FPS with a minimum of 25 FPS and maximum of 34 FPS, the High preset averages 25 FPS, and the Ultra preset averages 20 FPS. The 4K results are all well below the 30 FPS threshold for playable performance, with the Ultra preset being effectively a slideshow.

The full dataset shows that the Arc B370’s performance scales predictably with both resolution and settings, but the absolute numbers are too low for a demanding title like Doom at anything above 1080p Low. The minimum FPS values recorded only for the Medium preset at each resolution (71 at 1080p, 46 at 1440p, 25 at 4K) indicate that frame drops are severe when the GPU is under stress. The Ryzen 5 5600X’s role in these results is passive, as its high single-thread score of 3364 and 12 threads ensure that CPU-side frame generation is never the constraint. The data ultimately shows a system that can run Doom acceptably only at 1080p with reduced settings, with any attempt to increase quality or resolution resulting in a sub-60 FPS experience.
