Doom

The AMD Ryzen 7 5700X3D paired with the Intel Arc B580 produces a highly consistent scaling pattern in Doom, where frame rates degrade predictably as resolution increases from 1080p to 4K. At 1080p with Low settings, the combo delivers 182.2 FPS, but this drops to 119.7 FPS at 1440p and further to 66.9 FPS at 4K. This represents a 34% reduction from 1080p to 1440p and a 44% further reduction from 1440p to 4K, indicating that the GPU becomes progressively more stressed as pixel count grows. The pattern is uniform across all settings tiers, with High settings showing 135.2 FPS at 1080p, 88.4 FPS at 1440p, and 45.3 FPS at 4K. The scaling from 1440p to 4K is steeper than from 1080p to 1440p, suggesting that at 4K the render pipeline is hitting a harder throughput ceiling, likely tied to the GPU’s fill rate and memory bandwidth rather than the CPU’s compute capacity.

The drop from Ultra at 1080p (109.4 FPS) to Ultra at 1440p (70.4 FPS) is a 36% decline, while the drop from Ultra 1440p to Ultra 4K (38.9 FPS) is a 45% decline. This asymmetrical scaling points to the GPU being the limiting component at higher resolutions, as the CPU’s 8-core, 16-thread configuration with a 96 MB shared L3 cache remains largely underutilized in Doom’s workload at lower resolutions. The data shows that at 1080p, the combo can push well beyond 180 FPS on Low settings, which indicates the CPU is feeding frames fast enough, but the GPU’s 13.67 TFLOPS FP32 throughput becomes the bottleneck as resolution climbs. The 4K results, particularly the 38.9 FPS at Ultra, fall below the 60 FPS threshold, making 4K playable only at Low or Medium settings (66.9 and 58.5 FPS respectively).

Resolution Scaling

The measured FPS data reveals a clear resolution-dependent behavior where the frame rate penalty for moving up a resolution tier is not linear but steepens at 4K. From 1080p Low (182.2 FPS) to 1440p Low (119.7 FPS), the drop is 62.5 FPS, a 34% reduction. From 1440p Low to 4K Low (66.9 FPS), the drop is 52.8 FPS, a 44% reduction. This pattern repeats across all settings: for High, the 1080p-to-1440p drop is 46.8 FPS (35%), while the 1440p-to-4K drop is 43.1 FPS (49%); for Medium, the drops are 55.5 FPS (35%) and 44.6 FPS (43%) respectively; for Ultra, the drops are 39.0 FPS (36%) and 31.5 FPS (45%). The consistency of these percentages suggests a fixed architectural limit, likely the GPU’s 456.0 GB/s memory bandwidth and 192-bit bus width, which must serve more pixels at 4K (3840x2160) than at 1440p (2560x1440) or 1080p (1920x1080).

The fact that 4K Ultra (38.9 FPS) is less than half of 1080p Ultra (109.4 FPS) underscores the GPU-bound nature of this combo at higher resolutions. At 1080p, the CPU’s 3.00 GHz base and 4.10 GHz boost clocks, combined with its Zen 3 architecture, are sufficient to keep the Arc B580’s 2670 MHz boost clock fed, as evidenced by the 182.2 FPS Low result. However, the steep scaling at 4K indicates that the GPU’s 80 ROPs and 213.6 GPixel/s pixel rate are not enough to maintain high frame rates at that resolution, regardless of settings. The data suggests that for 4K gaming, users would need to drop to Low settings to approach playable frame rates, while 1440p offers a better balance with 88.4 FPS at High and 70.4 FPS at Ultra.

GPU Role

The Intel Arc B580’s memory configuration plays a pivotal role in these results. With 12 GB of GDDR6 memory on a 192-bit bus and 456.0 GB/s bandwidth, the GPU has ample capacity for Doom’s textures, but the bandwidth becomes a limiting factor at 4K. The 2375 MHz memory clock (19 Gbps effective) provides the throughput needed for 1080p and 1440p, but the data shows a clear ceiling at 4K where the 38.9 FPS Ultra result is only 21% of the 182.2 FPS 1080p Low result. The GPU’s 2560 shading units and 160 TMUs handle the compute and texture work, but the 80 ROPs are responsible for pixel output, and at 4K the 213.6 GPixel/s pixel rate is insufficient for high frame rates.

The Arc B580’s 2670 MHz base and boost clocks are identical, indicating a fixed clock behavior under load. This stability is reflected in the consistent scaling percentages across settings, as the GPU does not appear to throttle or boost variably based on resolution. The 13.67 TFLOPS FP32 performance is adequate for 1080p and 1440p, but at 4K the GPU’s compute resources are stretched, leading to the sub-60 FPS results at Medium (58.5 FPS) and High (45.3 FPS). The GPU’s 66th percentile ranking among all GPUs, with an average benchmark score of 23021, places it near the NVIDIA GeForce RTX 4060 (23181, deltaPct -0.7) and slightly ahead of the AMD Radeon 760M (22999, deltaPct 0.1), which contextualizes why 4K Ultra remains challenging.

How This Combo Ranks

In Doom specifically, this CPU-GPU combination ranks 1313 out of 1681 tested combos, placing it in the 22nd percentile of all system pairings. This rank is lower than what the individual component percentiles might suggest—the CPU sits at the 82nd percentile among all CPUs (avg benchmark score 24673), while the GPU is at the 66th percentile. The discrepancy indicates that Doom’s workload does not favor this pairing as strongly as other games might, likely due to the GPU’s mid-range positioning relative to the CPU’s strong multi-threaded performance. The CPU’s nearest rivals include the Intel Core i7-1360P (avg score 24627, deltaPct 0.2) and AMD Ryzen 5 7600X3D (avg score 24605, deltaPct 0.3), showing the 5700X3D is essentially tied with these in synthetic benchmarks, but the GPU’s rivals like the NVIDIA GeForce RTX 4060 (avg score 23181, deltaPct -0.7) slightly outperform it, which may explain the lower combo rank.

The rank of 1313 out of 1681 suggests that most other combos achieve higher frame rates in Doom, but this is not necessarily a condemnation of the hardware. The data shows that at 1080p, the combo delivers 135.2 FPS at High settings, which is smooth for most displays. The low rank is more indicative of the GPU’s ceiling at higher resolutions and the fact that Doom is a well-optimized title that can run well on weaker CPUs, meaning the CPU’s multi-threading advantage (16 threads, 96 MB L3 cache) does not translate to a disproportionately high frame rate in this specific game. The combo’s measured FPS values, particularly the 182.2 FPS at 1080p Low, demonstrate that the system is capable of high frame rates, but the overall rank reflects the aggregate performance across all settings and resolutions, where 4K results drag down the average.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results, with all settings exceeding 100 FPS. Low settings produce 182.2 FPS, Medium yields 158.6 FPS, High achieves 135.2 FPS, and Ultra drops to 109.4 FPS. The gap between Low and Ultra is 72.8 FPS, a 40% reduction, which is modest and indicates that the GPU has headroom at this resolution. At 2560x1440, the frame rates remain playable but show more separation: Low hits 119.7 FPS, Medium 103.1 FPS, High 88.4 FPS, and Ultra 70.4 FPS. The Low-to-Ultra gap is 49.3 FPS, a 41% reduction, similar to 1080p in percentage terms but with lower absolute values. At 3840x2160, the results are more constrained: Low reaches 66.9 FPS, Medium 58.5 FPS, High 45.3 FPS, and Ultra 38.9 FPS. The Low-to-Ultra gap is 28.0 FPS, a 42% reduction, but the absolute frame rates fall below the 60 FPS threshold for High and Ultra, making those settings impractical for smooth 4K play.

The data shows a clear tiering: 1080p is GPU-light with headroom, 1440p is balanced, and 4K is GPU-bound. For users targeting 60 FPS, this combo achieves it at 1080p on all settings, at 1440p on Low, Medium, and High (but not Ultra at 70.4 FPS), and at 4K only on Low (66.9 FPS). The 4K Medium result of 58.5 FPS is close to 60 but does not reach it, while 4K High and Ultra are significantly below. This breakdown indicates that the Arc B580’s 12 GB memory is sufficient for all settings, but its compute and pixel throughput are the limiting factors at 4K, as evidenced by the 38.9 FPS Ultra result. The consistency of the percentage gaps across resolutions (40-42%) suggests that the GPU’s performance scales uniformly with settings changes, but the absolute frame rates at 4K are too low for high-refresh displays.
