Doom

# How This Combo Ranks

The AMD Ryzen 5 3600 paired with the Intel Arc B580 lands at rank 1315 out of 1681 tested combos in Doom. That places this configuration in the lower third of all combinations, which is a surprising outcome given the individual components' benchmark standings. The CPU sits at the 76th percentile among all processors, while the GPU reaches the 66th percentile among all graphics cards — yet their combined performance in this specific title does not boost them proportionally.

This ranking gap suggests that Doom's engine responds to this particular pairing in ways that raw component percentiles don't predict. The data implies a potential bottleneck or driver overhead issue, rather than a fundamental lack of capability. When examining the nearest rivals for the CPU, the Intel Core i5-11400 scores 18150 against the Ryzen 5 3600's 18129 — a negligible delta of -0.1%. Similarly, the AMD Ryzen 5 7535HS sits at 18101, just 0.2% behind. These are effectively identical compute scores, yet the combo ranking here suggests the system's overall position owes more to the GPU's interaction with the game than to CPU compute headroom.

The GPU's nearest rivals tell a more telling story. The NVIDIA GeForce RTX 4060 scores 23181, which is -0.7% relative to the Arc B580's 23021 average. That places the Arc B580 within striking distance of one of the most popular contemporary graphics cards in aggregate benchmarks. Despite that, the combo rank of 1315/1681 indicates that Doom's specific rendering paths may not fully exploit the Arc B580's architectural strengths. The data invites a deeper investigation into whether this is a driver maturity issue or an inherent design limitation of the Xe2-HPG architecture under this game's workload.

GPU Role

The Intel Arc B580 brings 12 GB of GDDR6 memory across a 192-bit bus, delivering 456.0 GB/s of bandwidth. Memory clocks run at 2375 MHz, translating to 19 Gbps effective. The GPU's base and boost clocks are identical at 2670 MHz, which is an unusual characteristic that suggests the card operates at a fixed frequency under load. With 2560 shading units, 160 TMUs, and 80 ROPs, the architectural configuration is substantial for a mid-range offering.

In Doom, the GPU's role becomes clear when examining the measured FPS across settings at each resolution. At 4K Ultra, the average FPS drops to 37.5, which is below the generally accepted threshold for smooth gameplay. The 12 GB frame buffer is not the limiting factor here — even at 4K, Doom's textures fit comfortably within that capacity. Instead, the data points to the GPU's raw throughput as the constraint. The pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s sound impressive on paper, but the measured results indicate that the card's compute units are saturated at higher settings.

Interesting is the delta between Low and Ultra settings at each resolution. At 1080p, Low yields 183.9 FPS while Ultra drops to 110.8 FPS — a reduction of 73.1 FPS. At 4K, the same settings comparison shows 65.3 FPS versus 37.5 FPS, a 27.8 FPS gap. The shrinking absolute gap at higher resolutions suggests that the GPU becomes the primary bottleneck regardless of settings, whereas at 1080p the CPU can still feed the GPU enough to let settings matter more. The Arc B580's FP32 throughput of 13.67 TFLOPS is the likely ceiling for Doom's shading workload, and the data supports this interpretation.

Resolution Scaling

Moving from 1080p to 1440p to 4K reveals a consistent scaling pattern that illustrates the system's bottleneck behavior. At High settings, the average FPS goes from 133.9 at 1080p to 90 at 1440p, then plunges to 46.5 at 4K. That's a 33% drop from 1080p to 1440p, followed by a 48% drop from 1440p to 4K. The scaling is not linear — the 4K penalty is disproportionately severe, indicating that the GPU's memory bandwidth and compute resources are being exhausted.

At Low settings, the scaling is less punishing: 183.9 FPS at 1080p, 117.1 at 1440p, and 65.3 at 4K. The percentage drops are 36% and 44% respectively. The fact that Low settings still show a steep 4K decline suggests that even minimal shading work overwhelms the Arc B580 at that resolution. This is consistent with a GPU that has strong per-clock efficiency but limited total throughput — the 2670 MHz clock cannot compensate for the sheer pixel count at 4K.

The resolution scaling data also reveals where the CPU stops mattering. At 1080p Low, 183.9 FPS is achievable, which is high enough that the Ryzen 5 3600's 12 threads might be nearing their limit. However, at 1440p Low, the drop to 117.1 FPS is larger than what pure pixel-count scaling would predict (1920x1080 to 2560x1440 is a 78% pixel increase, yet FPS drops by 36%). This implies the GPU is already becoming the limiting factor at 1440p, and by 4K the CPU is mostly idle, waiting on the GPU to complete frames.

Settings Recommendations

The measured data provides clear guidance for optimal settings. At 1080p, Ultra settings deliver 110.8 FPS, which is smooth for fast-paced FPS gameplay. The jump from Ultra to High at 1080p yields 133.9 FPS — a 23.1 FPS improvement that many players would notice. Medium offers 159.1 FPS, and Low reaches 183.9 FPS. Given that Doom is a fast-paced shooter where higher frame rates directly improve responsiveness, Medium or High at 1080p appears to be the sweet spot, balancing visual fidelity with performance headroom.

At 1440p, the situation changes. Ultra drops to 71.5 FPS, which is playable but not ideal for competitive play. High delivers 90 FPS, and Medium reaches 104.7 FPS. The data suggests that Medium at 1440p gives the best experience — it stays above 100 FPS while retaining enough visual quality. Low at 1440p reaches 117.1 FPS, but the visual sacrifice may not be worth the extra 12.4 FPS over Medium.

At 4K, the recommendation becomes more constrained. High produces 46.5 FPS, which is below the 60 FPS target. Medium gives 55.4 FPS, still short of 60. Low reaches 65.3 FPS, just above the threshold. For 4K gameplay, Low settings are the only option that maintains acceptable fluidity, and even then, the margin is thin. The Ultra preset at 4K, at 37.5 FPS, should be avoided unless the player prioritizes visuals over playability.

Measured FPS Breakdown

At 1920x1080, the full settings spectrum shows: Low 183.9 FPS, Medium 159.1 FPS, High 133.9 FPS, and Ultra 110.8 FPS. The spread from Low to Ultra is 73.1 FPS, with each settings tier costing roughly 20-25 FPS. This linear degradation suggests the GPU scales predictably with shading complexity at this resolution.

Moving to 2560x1440, the numbers compress: Low 117.1 FPS, Medium 104.7 FPS, High 90 FPS, and Ultra 71.5 FPS. The spread narrows to 45.6 FPS. The proportional cost of Ultra versus Low grows from 40% at 1080p to 39% at 1440p — nearly identical, indicating the GPU handles both resolutions with similar efficiency relative to its own limits.

At 3840x2160, the breakdown is: Low 65.3 FPS, Medium 55.4 FPS, High 46.5 FPS, and Ultra 37.5 FPS. The spread is 27.8 FPS. Notably, the absolute FPS loss from Low to Ultra is smaller at 4K than at 1080p, but the percentage loss is larger — 43% versus 40%. This indicates that at 4K, the GPU is so heavily loaded that even dropping to Low settings cannot fully relieve the bottleneck, whereas at 1080p the settings have more room to influence performance.

CPU Role

The AMD Ryzen 5 3600 provides 6 cores and 12 threads, with a base clock of 3.60 GHz and a boost clock of 4.20 GHz. This Zen 2 architecture chip, built on a 7 nm process, has 32 MB of shared L3 cache and supports DDR4 memory with a dual-channel bus delivering 51.2 GB/s. In synthetic benchmarks, the CPU achieves a Cinebench R23 multi-core score of 15045 and a single-core score of 2124. The Passmark multi-thread score of 17700 and single-thread score of 2562 confirm its mid-range positioning.

In Doom, the CPU's role is most evident at 1080p Low settings, where the frame rate reaches 183.9 FPS. This is high enough that the CPU's 12 threads are likely near their limit for feeding the GPU. The 3DMark 8-thread score of 3844 and max-thread score of 4603 suggest that the CPU can handle substantial multi-threaded workloads, but Doom's engine may not scale perfectly across all 12 threads. The single-thread score of 696 in 3DMark is modest, and for a game that relies heavily on single-thread performance for game logic, this could be a limiting factor.

When comparing to rivals, the Ryzen 5 3600's average benchmark score of 18129 is nearly identical to the Intel Core i5-11400's 18150 (-0.1%) and the AMD Ryzen 5 7535HS's 18101 (+0.2%). This means the CPU is not a differentiator in this combo — any of these chips would produce similar results. The bottleneck in Doom at higher resolutions is clearly the GPU, as evidenced by the disproportionate FPS drops when moving from 1440p to 4K. At 1080p, the CPU and GPU are more balanced, but the data shows that the Arc B580 is the component that determines the ceiling.
