# Pc Building Simulator — AMD Ryzen 9 9950X3D + Intel Arc B390

The AMD Ryzen 9 9950X3D paired with the Intel Arc B390 produces a heavily GPU-limited experience in Pc Building Simulator, with frame rates ranging from 20 FPS at 4K Ultra to 125 FPS at 1080p Low. The 16-core, 32-thread Zen 5 processor sits in the 95th percentile among all CPUs, yet the integrated-class Arc B390 graphics solution, which ranks in the 9th percentile among all GPUs, becomes the decisive bottleneck across every tested configuration. The data reveals a system where the CPU's enormous headroom is largely untapped, while the GPU struggles to maintain playable frame rates at higher resolutions and quality settings.

Resolution Scaling

The measured FPS data shows a steep and consistent performance drop as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average frame rate falls from 125 FPS at 1080p to 79 FPS at 1440p, then further to 41 FPS at 4K — a decline of 67% from 1080p to 4K. This pattern indicates that the rendering pipeline is almost entirely bound by the GPU's pixel throughput capabilities rather than any CPU-side limitation.

The scaling behavior becomes more pronounced at higher quality presets. At High settings, the average drops from 62 FPS at 1080p to 39 FPS at 1440p (a 37% reduction) and then to 21 FPS at 4K (a 66% reduction from 1080p). Ultra settings follow a similar trajectory: 59 FPS at 1080p, 38 FPS at 1440p, and 20 FPS at 4K. The fact that Ultra at 4K produces nearly identical average FPS to High at 4K (20 vs. 21) suggests the GPU has hit a hard computational ceiling around 20 FPS at that resolution, regardless of minor settings adjustments.

The Medium preset shows the most complete data with minimum and maximum frame rates recorded. At 1080p Medium, the average is 88 FPS with a range of 75 to 102 FPS. Moving to 1440p Medium drops the average to 56 FPS (range 47–64), and 4K Medium further reduces it to 29 FPS (range 25–34). The minimum frame rates at each resolution track closely with the averages, indicating relatively stable frame pacing without severe spikes or hitches — the performance degradation is steady and predictable as pixel count increases.

This resolution scaling profile is characteristic of a system where the GPU's fill rate and shader throughput are the primary constraints. The Arc B390, with its 24 ROPs and 60.00 GPixel/s pixel rate, simply cannot maintain high frame rates at 4K, where the pixel workload quadruples compared to 1080p. The data shows that even dropping from Ultra to Low at 4K only recovers from 20 FPS to 41 FPS — still far from smooth gameplay.

CPU Role

The AMD Ryzen 9 9950X3D brings substantial compute resources to this pairing. With 16 cores and 32 threads based on the Zen 5 architecture (Granite Ridge), the processor operates at a base clock of 4.30 GHz and a boost clock of 5.70 GHz. The 128 MB of L3 cache, split as 80 KB L1 and 1 MB L2 per core, provides ample on-die storage for game data. The CPU's benchmark scores reflect its high-end positioning: a Cinebench R23 multicore score of 42018 and single-core score of 2259, with a Geekbench multicore result of 26736.

In the context of this game, however, the CPU's capabilities appear vastly underutilized. The measured frame rates show almost no evidence of CPU-side bottlenecks. At 1080p Low, where CPU limitations would typically surface first, the system achieves 125 FPS — the highest measured result in the entire dataset. If the CPU were the limiting factor, we would expect to see frame rates plateau across different resolutions at this settings level. Instead, the 1080p-to-4K drop from 125 to 41 FPS at Low settings demonstrates that the GPU is the sole constraint.

The CPU's 3DMark scores provide additional context. The 16-thread test score of 16374 and max-thread score of 17184 show strong multi-threaded performance, while the single-thread score of 1292 indicates competent single-core capability. The Passmark multithread score of 70255 and physics score of 5670 further confirm the processor's ability to handle complex simulations. Pc Building Simulator, as a simulation title, might be expected to leverage CPU resources for game logic, but the frame rate data suggests otherwise — the GPU remains the dominant factor at every measured configuration.

Compared to its nearest rivals in the CPU benchmark database, the 9950X3D leads the field. It edges out the AMD Ryzen 7 PRO 9755 by 0.1% (75779 vs. 75738 average benchmark score), matches the Ryzen 7 PRO 9755X3D at a 0.1% delta (75716), and sits 0.3% ahead of the AMD EPYC 8224P (75582) and 0.4% ahead of the Intel Core Ultra 9 285 (75488). This margin is negligible in real-world terms, but it places the 9950X3D at the top of its immediate comparison group.

GPU Role

The Intel Arc B390 is the clear performance limiter in this configuration. Based on the Xe3-LPG architecture (Panther Lake chip) and manufactured on Intel's 3 nm process, this integrated graphics solution features 1536 shading units, 48 texture mapping units, and 24 ROPs. The GPU operates at a base clock of 300 MHz with a boost clock of 2500 MHz, delivering 7.680 TFLOPS of FP32 compute and a pixel rate of 60.00 GPixel/s.

The GPU's benchmark presence is minimal — a single 3DMark Steel Nomad DX12 score of 1482 places it in the 9th percentile among all GPUs. Its nearest rivals in the database are all legacy or entry-level parts: the NVIDIA GeForce GT 520MX (score 1463, 1.3% behind), NVIDIA GeForce 800M (1460, 1.5% behind), NVIDIA GeForce GT 625 OEM (1446, 2.5% behind), and NVIDIA GeForce GT 710 (1443, 2.7% behind). This positioning confirms the Arc B390's performance class as barely above ancient integrated or low-end discrete solutions.

The memory configuration is system-shared, with the GPU relying on main system memory rather than dedicated VRAM. The bandwidth is listed as "System Dependent," meaning performance will vary based on the host platform's memory subsystem. The 9950X3D's dual-channel DDR5 support with 89.6 GB/s memory bandwidth provides the GPU with a reasonable memory pathway, but shared memory inherently limits texture and geometry throughput compared to dedicated VRAM.

In Pc Building Simulator, the GPU's limitations manifest clearly across all settings. The highest measured frame rate of 125 FPS at 1080p Low is achievable, but this drops to 59 FPS at 1080p Ultra — a 53% reduction. The GPU's 12 RT cores and DirectX 12 Ultimate support (12_2) are present but largely irrelevant at these performance levels, as the frame rates suggest the GPU is overwhelmed by basic rasterization workloads before any ray tracing demands would come into play.

How This Combo Ranks

The combination of the AMD Ryzen 9 9950X3D with the Intel Arc B390 ranks 2650 out of 3002 tested combos in Pc Building Simulator. This places the system in the bottom 12% of all configurations tested for this game, which is a striking result given the CPU's top-tier status. The ranking reflects the GPU's severe performance constraint: a processor that sits in the 95th percentile of all CPUs is paired with a GPU in the 9th percentile, and the game's frame rates align much more closely with the GPU's low standing.

The rank disparity between the CPU and GPU performance percentiles (95th vs. 9th) illustrates the magnitude of the imbalance. In a game like Pc Building Simulator, where the data shows GPU-bound behavior at every resolution and settings combination, the CPU's advantages in multi-threaded compute and large cache are effectively neutralized. The combo rank of 2650 out of 3002 indicates that the vast majority of other tested systems — even those with far weaker processors — deliver better frame rates simply because they include more capable graphics solutions.

The measured frame rates corroborate this ranking. At 4K Ultra, the system produces 20 FPS average, which is below the threshold for smooth gameplay in most titles. Even at 1080p High, the 62 FPS average is barely acceptable, and the 59 FPS at 1080p Ultra falls just short of common 60 FPS targets. The only configuration that exceeds 60 FPS is 1080p Low at 125 FPS, which requires significant visual compromises. This performance profile is consistent with a combo rank in the bottom 12% — the system can handle the game at reduced settings and resolutions but struggles at higher quality levels.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this system depend on the target resolution and the user's tolerance for visual compromises. At 1920x1080, the Medium preset delivers an 88 FPS average with a minimum of 75 FPS, making it the best balance between visual quality and smoothness. The High preset at 1080p produces 62 FPS average — playable but with less headroom, while Ultra drops to 59 FPS average. For users who prioritize frame rate, Low at 1080p offers 125 FPS, but the visual downgrade may not be worth the gain.

At 2560x1440, the Medium preset provides a 56 FPS average with a minimum of 47 FPS, which is marginally playable but may show occasional dips below smooth thresholds. Low at 1440p produces 79 FPS, making it the only 1440p setting that comfortably exceeds 60 FPS. High at 1440p drops to 39 FPS, and Ultra to 38 FPS — both below acceptable levels for most players. The data suggests that 1440p users should either accept Low settings or drop to 1080p Medium for a better experience.

At 3840x2160, no setting achieves playable frame rates. The best result is Low at 41 FPS, followed by Medium at 29 FPS, High at 21 FPS, and Ultra at 20 FPS. All of these are below 45 FPS, which most players would find choppy. The 4K data indicates that this system is not viable for 4K gaming in Pc Building Simulator, regardless of settings. Users targeting 4K should consider a different GPU or accept that the game will run at reduced quality with sub-30 FPS performance.

Measured FPS Breakdown

At 1920x1080, the system produces its best results. Low settings achieve 125 FPS average, Medium delivers 88 FPS with a range of 75–102 FPS, High reaches 62 FPS, and Ultra manages 59 FPS. The progression from Low to Ultra shows a 53% performance reduction, with the largest single drop occurring from Medium to High (88 to 62 FPS, a 30% decrease).

At 2560x1440, performance degrades noticeably. Low settings produce 79 FPS average, Medium delivers 56 FPS with a range of 47–64 FPS, High reaches 39 FPS, and Ultra achieves 38 FPS. The 1440p results represent approximately a 36–38% reduction from 1080p across all settings, consistent with the increased pixel count.

At 3840x2160, the system struggles across the board. Low settings produce 41 FPS average, Medium delivers 29 FPS with a range of 25–34 FPS, High reaches 21 FPS, and Ultra manages 20 FPS. The 4K results show a 69–72% reduction from 1080p, with the gap between settings narrowing as the GPU approaches its computational limits. The minimum frame rate data for Medium at each resolution (75 FPS at 1080p, 47 FPS at 1440p, 25 FPS at 4K) shows consistent frame pacing without major stutter events, but the averages are simply too low at higher resolutions.
