# Pc Building Simulator — AMD Ryzen 7 3700X + Intel Arc B390

Pc Building Simulator, a simulation title from 2019, presents an unusual performance landscape for this combination of an 8-core AMD Ryzen 7 3700X and Intel's integrated Arc B390 graphics. The measured frame rates across resolutions and settings reveal a system that is heavily constrained by the GPU, yet the CPU's strong multi-threaded capabilities prevent the experience from collapsing entirely at lower resolutions. The data shows a configuration that ranks near the bottom of the tested pool, sitting at rank 2650 out of 3002 combos, placing it in the 12th percentile of all tested systems for this game.

Resolution Scaling

The frame rate behavior across the three tested resolutions—1920x1080, 2560x1440, and 3840x2160—tells a clear story about where the bottleneck resides. At 1080p with Low settings, the system produces 125 FPS, which drops to 79 FPS at 1440p and further to 41 FPS at 4K. This represents a 37% performance loss when moving from 1080p to 1440p, and a 67% loss from 1080p to 4K. Such steep declines are characteristic of a GPU-limited scenario, where the rendering workload increases dramatically with pixel count.

The scaling pattern becomes even more pronounced when examining the High preset. At 1080p High, the average is 62 FPS; at 1440p High, it falls to 39 FPS (a 37% reduction); and at 4K High, it bottoms out at 21 FPS (a 66% reduction from 1080p). The consistency of these percentage drops across different settings levels suggests that the Intel Arc B390's compute throughput is the limiting factor, not memory bandwidth or CPU overhead. The Arc B390's integrated nature, with system-shared memory and a system-dependent bandwidth, means that higher resolutions impose proportionally larger penalties as the GPU struggles to fill more pixels.

Notably, the gap between Low and High settings widens as resolution increases. At 1080p, the difference between Low (125 FPS) and High (62 FPS) is 63 FPS. At 4K, the same comparison yields only a 20 FPS difference (41 vs 21 FPS). This compression of the settings range at higher resolutions further confirms that the GPU is saturated; when pixel throughput is the ceiling, reducing settings can only recover so much performance. The Ultra preset at 4K delivers 20 FPS, barely lower than High at 21 FPS, indicating that the highest settings are not meaningfully more demanding on this already-overwhelmed GPU.

FAQ

Q: What is the best resolution for this combo in Pc Building Simulator?

A: The data indicates that 1920x1080 is the only resolution where playable frame rates are consistently achieved. At 1080p, all settings presets exceed 59 FPS average, with Low reaching 125 FPS and Medium hitting 88 FPS. At 1440p, only the Low preset (79 FPS) stays above 60 FPS, while 4K never exceeds 41 FPS at any setting.

Q: How does the Ultra preset compare to High across resolutions?

A: The Ultra preset is only 3-5 FPS lower than High at each resolution: 59 vs 62 FPS at 1080p, 38 vs 39 FPS at 1440p, and 20 vs 21 FPS at 4K. The measured data shows that the visual quality increase from High to Ultra costs very little performance, making Ultra a reasonable choice when the baseline frame rate is already acceptable.

Q: Is the CPU or GPU the primary bottleneck in this game?

A: The frame rate scaling strongly indicates GPU limitation. The Arc B390, which ranks at the 9th percentile among all GPUs with a 3DMark Steel Nomad DX12 score of 1482, cannot keep pace with the Ryzen 7 3700X, which sits at the 84th percentile among CPUs. The CPU's PassMark multi-thread score of 22458 provides ample headroom, but the GPU's 7.680 TFLOPS FP32 throughput caps performance.

Q: What settings preset delivers the smoothest experience at 1080p?

A: The Medium preset at 1080p provides a strong balance, with an average of 88 FPS and a minimum of 75 FPS. This 75 FPS floor means the system never drops below what most displays can refresh, while the 102 FPS maximum shows headroom. Low is faster (125 FPS average) but sacrifices visual fidelity, and High/Ultra both sit near 60 FPS.

Q: How does this combo rank against other tested configurations?

A: This pairing ranks 2650th out of 3002 tested combos in Pc Building Simulator, placing it in the bottom 12% of systems. The ranking reflects the GPU's weak absolute performance; the integrated Arc B390 is comparable to legacy discrete GPUs like the NVIDIA GeForce GT 710, which scores 1443 in 3DMark Steel Nomad versus the Arc's 1482.

Q: Can this system handle 4K gaming at any settings?

A: The measured data says no for comfortable play. At 4K Low, the average is 41 FPS, which is borderline but below the 60 FPS target most gamers prefer. At 4K Medium, the average drops to 29 FPS with a minimum of 25 FPS and maximum of 34 FPS. The 4K High and Ultra presets deliver 21 and 20 FPS respectively, which are effectively unplayable.

GPU Role

The Intel Arc B390 is the definitive performance limiter in Pc Building Simulator for this system. This integrated GPU, built on a 3 nm process with the Xe3-LPG architecture, operates with a base clock of 300 MHz and a boost clock of 2500 MHz. Its memory configuration is entirely system-shared, with no dedicated VRAM, which means bandwidth is system-dependent and cannot be quantified independently. The GPU's compute resources include 1536 shading units, 48 texture mapping units, and 24 render output units, along with 12 ray tracing cores. The pixel rate is 60.00 GPixel/s and the texture rate is 120.0 GTexel/s, with FP32 performance rated at 7.680 TFLOPS.

In the 3DMark Steel Nomad DX12 benchmark, the Arc B390 scores 1482, placing it at the 9th percentile of all GPUs. Its nearest rivals in that benchmark are the NVIDIA GeForce GT 520MX (1463, 1.3% slower), GeForce 800M (1460, 1.5% slower), GT 625 OEM (1446, 2.5% slower), and GT 710 (1443, 2.7% slower). These are all entry-level or legacy parts, which contextualizes the Arc B390's position: it performs like a very old discrete GPU despite being a modern integrated solution. The GPU's 80 W TDP and IGP slot width reflect its integrated nature, and it draws power through no external connectors.

The practical impact of this GPU limitation is visible in the measured FPS data. At 1080p Low, the system reaches 125 FPS, but this is the ceiling; no settings combination at any resolution exceeds this. The GPU's inability to maintain higher frame rates at 1440p and 4K, even at Low settings, shows that the pixel fill rate and shading capacity are fundamentally insufficient for higher resolutions in this simulation title. The fact that Low settings at 4K (41 FPS) are only 33% of the 1080p Low result (125 FPS) quantifies the GPU's rendering ceiling.

Settings Recommendations

Based on the measured frame rates, the Medium preset at 1920x1080 is the optimal configuration for this combination. The 88 FPS average with a 75 FPS minimum and 102 FPS maximum provides a smooth experience that stays above common 60 FPS display refresh rates. The minimum of 75 FPS is particularly important, as it indicates that even in demanding scenes, the frame rate does not dip below playable thresholds. At 1080p, the Low preset (125 FPS average) is faster but offers reduced visual quality, while High (62 FPS) and Ultra (59 FPS) both fall below the 88 FPS Medium result.

The interesting finding is that Ultra at 1080p, at 59 FPS average, is only 3 FPS slower than High (62 FPS). This small delta suggests that the Ultra preset is not meaningfully more demanding on this GPU, so there is little reason to choose High over Ultra if visual fidelity is a priority and the 59 FPS average is acceptable. However, the Medium preset's 88 FPS average provides substantially more headroom for frame time spikes, which matters more in a game where scene complexity can vary.

At 2560x1440, the only viable option is Low, which delivers 79 FPS average. Medium at 1440p drops to 56 FPS with a 47 FPS minimum, which is borderline but might be acceptable for less demanding players. High (39 FPS) and Ultra (38 FPS) at 1440p are not recommended for smooth gameplay. At 3840x2160, no preset achieves the 60 FPS target; the best result is Low at 41 FPS, and Medium drops to 29 FPS. Users with 4K displays should either reduce resolution to 1440p or accept sub-60 FPS performance.

The measured data indicates that the Medium preset at 1080p is the sweet spot for this hardware combination, delivering the best balance of frame rate stability and visual quality. For players who prioritize maximum frame rates, Low at 1080p is the fastest option, but the 37 FPS improvement over Medium may not justify the visual downgrade.

How This Combo Ranks

In the database of tested combinations for Pc Building Simulator, this pairing of AMD Ryzen 7 3700X and Intel Arc B390 ranks 2650th out of 3002 total combos. This places the system in the bottom 12% of all tested configurations, reflecting the GPU's severe performance deficit relative to the rest of the field. The rank of 2650 means that 88% of tested combos deliver higher frame rates in this game, which is consistent with the Arc B390's 9th percentile GPU ranking.

The CPU itself is not the issue. The Ryzen 7 3700X, an 8-core/16-thread Zen 2 processor, ranks at the 84th percentile among all CPUs with an average benchmark score of 34260. Its nearest rivals include the AMD Ryzen AI 7 350 (34222, 0.1% slower), AMD EPYC 4244P (34220, 0.1% slower), Intel Core i5-13450HX (34333, 0.2% faster), and Intel Core Ultra 7 165H (34083, 0.5% slower). This CPU is competitive with modern mid-range processors, but it is paired with a GPU that bottlenecks it severely.

The contrast between the CPU's 84th percentile and the GPU's 9th percentile, combined with the combo's 12th percentile ranking, illustrates the extent of the imbalance. The combo rank is closer to the GPU percentile than the CPU percentile, confirming that the integrated GPU determines the system's overall gaming performance. In a game like Pc Building Simulator, which is CPU-intensive in simulation logic but still requires GPU rendering, the CPU's 16 threads help maintain baseline performance at low resolutions, but the GPU cannot scale to higher resolutions.

Measured FPS Breakdown

At 1920x1080, the system demonstrates its best performance across all settings. The Low preset achieves an average of 125 FPS, which is the highest recorded result for this combination at any resolution or setting. The Medium preset delivers 88 FPS average with a minimum of 75 FPS and maximum of 102 FPS, showing good frame time consistency. The High preset averages 62 FPS, and the Ultra preset averages 59 FPS, both without recorded minimum or maximum values.

At 2560x1440, the performance drops significantly across all presets. The Low preset averages 79 FPS, a 37% reduction from the 1080p Low result. The Medium preset averages 56 FPS with a minimum of 47 FPS and maximum of 64 FPS, indicating that while the average is playable, the minimum dips below 50 FPS. The High preset averages 39 FPS, and the Ultra preset averages 38 FPS. The drop from 1080p to 1440p is consistent at approximately 37% across all settings, reinforcing the GPU-bound nature of the system.

At 3840x2160, the system struggles to maintain playable frame rates. The Low preset averages 41 FPS, which is the only 4K result above 30 FPS. The Medium preset averages 29 FPS with a minimum of 25 FPS and maximum of 34 FPS, showing that even the minimum can dip below 30 FPS. The High preset averages 21 FPS, and the Ultra preset averages 20 FPS. The 4K Medium result, with its recorded min/max range, provides the most complete picture of the GPU's limitations at this resolution: the 25 FPS minimum represents the worst-case scenario for this configuration.

CPU Role

The AMD Ryzen 7 3700X provides the computational foundation for this system, and its capabilities are far in excess of what the integrated GPU can utilize in Pc Building Simulator. This 8-core, 16-thread processor from the 3000 series operates with a base clock of 3.60 GHz and a boost clock of 4.40 GHz. Built on TSMC's 7 nm process with Zen 2 architecture (codename Matisse), the chip contains 3,800 million transistors on a 74 mm² die. It supports dual-channel DDR4 memory with a bandwidth of 51.2 GB/s and connects via PCIe Gen 4 with 24 lanes from the CPU.

The CPU's benchmark results show strong multi-threaded performance. In Cinebench R15, it scores 2092 in multicore and 204 in singlecore. Geekbench results show 8899 in multicore and 1593 in singlecore. PassMark tests reveal a multi-thread score of 22458 and a single-thread score of 2656. Specific workload tests include data compression at 296379, data encryption at 18900, extended instructions at 19241, find prime numbers at 99, floating point math at 39005, integer math at 66399, physics at 1181, and random string sorting at 32131. The average benchmark score is 34260, placing it at the 84th percentile of all CPUs.

In Pc Building Simulator, the CPU's 8 cores and 16 threads are more than sufficient to handle the simulation logic, which involves tracking components, temperatures, and system interactions. The 32 MB L3 cache and 512 KB L2 per core provide ample data storage for game state. However, the CPU's performance headroom is wasted at higher resolutions because the Arc B390 cannot render frames fast enough to leverage it. At 1080p Low, the system achieves 125 FPS, which suggests the CPU can feed the GPU adequately at lower quality settings, but the GPU's 9th percentile ranking means it cannot extend this performance to higher resolutions or settings.

The CPU's nearest rivals in benchmark scores include the AMD Ryzen AI 7 350 (0.1% faster), AMD EPYC 4244P (0.1% faster), Intel Core i5-13450HX (0.2% faster), and Intel Core Ultra 7 165H (0.5% slower). This places the 3700X in the same performance class as modern mid-range and upper-mid-range processors, despite being released earlier. The fact that this CPU is not the limiting factor in this game is clear from the frame rate scaling: if the CPU were the bottleneck, the performance drop from 1080p to 4K would be less severe, and the Low versus Ultra difference at 4K would be more pronounced. Instead, the data shows a GPU-limited configuration where the CPU's capabilities are underutilized.
