Pc Building Simulator

The AMD Ryzen 7 5700G paired with the Intel Arc B580 presents a compelling mid-range configuration for Pc Building Simulator — a simulation title that is oddly demanding on both CPU and GPU depending on the scene. The measured frame rates across three resolutions and four quality presets reveal a system that is well-balanced at 1080p but progressively becomes GPU-bound as pixel count increases. This analysis breaks down the data to show where the bottleneck shifts and what that means for practical use.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 produces a sharp, predictable drop in frame rate, but the magnitude of that drop depends heavily on the quality preset. At Low settings, the system delivers 217.3 FPS at 1080p, which falls to 139.1 FPS at 1440p (a 36% reduction) and further to 74 FPS at 4K (a 66% reduction from 1080p). This scaling curve is steep because at Low settings, the CPU is doing a larger share of the work relative to the GPU; the Ryzen 7 5700G’s eight Zen 3 cores are not the limiting factor at this resolution, so the Arc B580’s raw throughput is what governs the drop.

At High settings, the scaling is more linear in percentage terms: 1080p yields 108.7 FPS, 1440p yields 70 FPS (a 35% drop), and 4K yields 36.5 FPS (a 66% drop from 1080p). The near-identical percentage drops between Low and High suggest that the GPU is the primary limiter once the resolution exceeds 1440p, regardless of preset. The Ultra preset tells a slightly different story: 104.4 FPS at 1080p drops to 65.2 FPS at 1440p (a 37% drop) and then to 36.3 FPS at 4K (a 65% drop from 1080p). This consistency — roughly a two-thirds reduction from 1080p to 4K across all presets — indicates that the frame rate ceiling at 4K is set by the Arc B580’s memory bandwidth and shader throughput, not by CPU thread scheduling.

The data also shows that the gap between Medium and High is smaller than the gap between Low and Medium. At 1440p, Medium produces 94.3 FPS while High produces 70 FPS — a 34% difference — whereas Low produces 139.1 FPS, a 48% jump over Medium. This non-linear scaling suggests that the game’s settings hierarchy has a steep cost for enabling certain visual features (likely shadows and reflections) that disproportionately tax the GPU. At 4K, the Medium to High gap narrows to 36.5% (49.9 to 36.5 FPS), reinforcing that the GPU is saturated at that resolution and additional settings have diminishing returns on visual quality relative to frame rate.

GPU Role

The Intel Arc B580 is built on the Xe2-HPG architecture with a base and boost clock of 2670 MHz — a fixed boost that suggests consistent sustained performance under load. Its 12 GB of GDDR6 memory on a 192-bit bus provides 456.0 GB/s of bandwidth, which is a critical resource for Pc Building Simulator’s detailed 3D models and texture-heavy menus. The data shows that at 4K Ultra, the system averages just 36.3 FPS, which is nearly identical to the 4K High result of 36.5 FPS. This near-tie indicates that the GPU is not running out of memory at 12 GB; rather, the 80 ROPs and 2560 shading units are the constraint, as the pixel rate of 213.6 GPixel/s is insufficient to push 4K with heavy effects enabled.

The Arc B580’s 13.67 TFLOPS of FP32 compute is respectable but not exceptional for this workload. At 1080p Low, the 217.3 FPS result suggests the CPU is still capable of feeding the GPU, but at 1080p Ultra (104.4 FPS), the GPU is clearly the bottleneck, as the CPU’s single-thread performance (3dmark single thread score of 899) is not high enough to mask the GPU’s limitations. The Geekbench Vulkan score of 109,672 and OpenCL score of 92,821 confirm that the GPU is strong in compute-heavy tasks, but Pc Building Simulator relies more on draw calls and fill rate than on raw compute, which is why the 4K results plateau around 36-49 FPS rather than scaling with the GPU’s TFLOPS.

The GPU’s 12 GB frame buffer is well-suited for this game, as even at 4K Ultra the data shows no signs of a memory-related stutter or regression — the average FPS of 36.3 is only 0.5% lower than High (36.5), which is within noise. The 456.0 GB/s bandwidth is ample for the game’s textures, but the 192-bit bus width means that the Arc B580 cannot leverage its memory advantage to overcome the ROP bottleneck at 4K. In contrast, at 1440p the GPU has enough bandwidth to deliver 94.3 FPS at Medium, which is a playable experience for a simulation title.

Settings Recommendations

For a 60 FPS target at 1920x1080, the data shows that High settings (108.7 FPS) are the sweet spot — they provide a 32% performance buffer over the 60 FPS target while offering substantial visual quality over Medium (153.7 FPS). Ultra at 1080p (104.4 FPS) is only 4% slower than High, so if the display supports it, Ultra is a viable choice, but High is recommended for stable frame pacing in scenes with many objects.

At 2560x1440, the situation is more nuanced. Medium (94.3 FPS) is the only preset that comfortably exceeds 60 FPS, while High (70 FPS) is playable but leaves little headroom for heavy scenes. Low (139.1 FPS) is overkill for visual quality, and Ultra (65.2 FPS) is borderline — it drops below 60 FPS in the most demanding moments. The recommendation is Medium for a locked 60 FPS experience, or High if the user prefers visuals and can tolerate occasional dips to the low 60s.

At 3840x2160, no preset achieves 60 FPS. The best result is Low at 74 FPS, which is playable but sacrifices almost all visual fidelity. Medium (49.9 FPS) and High (36.5 FPS) are not smooth enough for a simulation where precise mouse movement matters, and Ultra (36.3 FPS) is indistinguishable from High in performance. For 4K, the data suggests using Low if frame rate is paramount, or accepting that this combo is not suited for 4K gaming beyond Low settings. The 1440p Medium result is the best balance of quality and performance across all resolutions.

How This Combo Ranks

The AMD Ryzen 7 5700G + Intel Arc B580 combination ranks 1363 out of 1769 tested combos for Pc Building Simulator, placing it in the 23rd percentile of all configurations. This is a below-average ranking, but the context matters: the benchmark database includes many high-end CPUs and GPUs that are overkill for this simulation. The combo’s ranking is dragged down by the CPU’s integrated graphics heritage — the Ryzen 7 5700G is a desktop APU with 8 cores and 16 threads, but its 3dmark max threads score of 6627 is modest compared to dedicated gaming CPUs.

The CPU’s benchmark scores are competitive with its nearest rivals: it is 0.3% behind the AMD Ryzen 7 6800U, 0.4% ahead of the Intel Xeon D-2752TER, and 0.5% ahead of the Intel Core 5 210H in average benchmark score. This puts the 5700G in a tight cluster of mid-range processors, and its 83rd percentile vs all CPUs indicates it is a strong general-purpose chip. However, for Pc Building Simulator, the game’s reliance on single-threaded performance (the CPU scores just 899 in 3dmark single thread) means that the 5700G’s multi-core advantage (cinebench r23 multicore of 20755) is not fully utilized.

The GPU’s ranking is 66th percentile vs all GPUs, and its nearest rival is the NVIDIA GeForce RTX 4060, which is 0.7% ahead. This is a tight margin, and the Arc B580’s Passmark G3D score of 15,748 confirms it trades blows with the RTX 4060 in synthetic tests. In Pc Building Simulator, the 4K results (36.5 FPS at High) suggest the GPU is performing as expected for its class, but the combo’s overall rank of 1363 is below the median because the game is more CPU-sensitive than most modern titles, and the 5700G’s single-thread performance is a bottleneck at lower resolutions.

FAQ

Q: Is the AMD Ryzen 7 5700G or the Intel Arc B580 the bottleneck in this game?

A: At 1080p and 1440p, the GPU is the primary limiter — the data shows frame rates scale with settings (e.g., 217.3 FPS at 1080p Low vs 104.4 FPS at 1080p Ultra). At 4K, the GPU is fully saturated, as all presets except Low (74 FPS) fall below 50 FPS, indicating the Arc B580’s 80 ROPs cannot keep up with 4K pixel counts.

Q: Can this combo achieve 60 FPS at 4K?

A: No. The highest 4K result is 74 FPS at Low settings, but Medium (49.9 FPS), High (36.5 FPS), and Ultra (36.3 FPS) all fall below 60 FPS. The data shows that 4K gaming is only feasible at Low settings for a smooth experience.

Q: What is the best settings preset for 1440p gaming?

A: Medium at 94.3 FPS is the recommended choice, as it provides a 57% buffer over the 60 FPS target. High (70 FPS) is also playable but leaves less headroom for complex scenes, while Ultra (65.2 FPS) is marginal and may drop below 60 FPS in busy areas.

Q: How does the Intel Arc B580 compare to the NVIDIA GeForce RTX 4060 in this game?

A: The Arc B580’s average benchmark score is 0.7% lower than the RTX 4060, and its Passmark G3D score of 15,748 is comparable. In this game, the 4K FPS results are low for both cards, but the data shows the Arc B580 is not underperforming its class — the game is simply heavy on fill rate.

Q: Does the 12 GB VRAM on the Arc B580 help at 4K?

A: The data suggests yes — the 4K results do not show a sudden drop between High (36.5 FPS) and Ultra (36.3 FPS), which would indicate a VRAM capacity issue. The 456.0 GB/s bandwidth is sufficient, but the GPU’s ROP count is the limiting factor at 4K, not memory size.

Q: Is the Ryzen 7 5700G a good match for the Arc B580 in this game?

A: The combo ranks 1363 out of 1769, which is below average. The CPU’s single-thread score of 899 in 3dmark limits 1080p performance (217.3 FPS at Low), but at higher resolutions the GPU takes over, so the pairing is acceptable for 1440p Medium or 1080p High. The CPU’s 83rd percentile overall suggests it is a capable processor, but this game’s engine favors faster single-core performance.
