Pc Building Simulator

The AMD Ryzen 7 7700 paired with the Intel Arc B390 presents a fascinating case study in system bottlenecks within Pc Building Simulator. The data indicates a configuration where a high-end 2023 CPU is coupled with a graphics solution that benchmarks in the lowest percentile, resulting in a gaming experience that is almost entirely dictated by the GPU's limitations. The measured FPS across resolutions and settings provides a clear narrative of a system struggling to maintain playable frame rates at higher graphical loads, while the CPU's substantial headroom remains largely untapped.

Resolution Scaling

The FPS drop from 1080p to 4K is stark and reveals the GPU as the definitive limiting component. At 1080p Low settings, the system produces 125 FPS, but this falls to 79 FPS at 1440p and plummets to 41 FPS at 4K. This represents a 67% reduction in average FPS from 1080p to 4K, a scaling pattern characteristic of a GPU that is being saturated far before the CPU can contribute. The data implies that as resolution increases, the rendering workload on the Intel Arc B390 grows exponentially, and its limited pixel throughput becomes the sole bottleneck.

The scaling from 1080p to 1440p is similarly telling, with a 37% performance drop, while the jump from 1440p to 4K incurs a further 48% loss. This non-linear degradation suggests that the Arc B390's rendering capabilities are exhausted quickly, and the system's frame rate is directly proportional to the number of pixels the GPU can process. The fact that the AMD Ryzen 7 7700, with its 8 cores and 5.30 GHz boost clock, is capable of far higher frame rates in other workloads makes it clear that the GPU is the primary constraint, a conclusion reinforced by the GPU's 9th percentile ranking among all tested GPUs.

At 1080p, the system shows its best performance, but the gap between Low (125 FPS) and Ultra (59 FPS) settings is a massive 53% drop. This indicates that even at the lowest resolution, the GPU is the limiting factor, and any increase in graphical fidelity directly impacts performance. The data suggests that the CPU's role is to feed frames to the GPU, but the GPU is unable to keep up, making the resolution scaling a direct reflection of the Arc B390's compute limitations rather than any CPU constraint.

How This Combo Ranks

The combination of the AMD Ryzen 7 7700 and Intel Arc B390 ranks 2650 out of 3002 tested combinations within Pc Building Simulator. This places the combo in the bottom 12% of all system configurations, a position that is unsurprising given the GPU's performance data. The rank reflects a system where a top-tier CPU is paired with a GPU that sits in the 9th percentile, creating a severe performance imbalance that manifests as poor overall frame rates.

The combo's rank is directly attributable to the GPU's weak benchmark scores. The Intel Arc B390 has an average benchmark score of 1482, placing it just 1.3% ahead of the NVIDIA GeForce GT 520MX and 2.7% ahead of the NVIDIA GeForce GT 710. These rivals are entry-level GPUs from previous generations, and the data suggests this combo's performance is in that same performance tier, despite the modern architecture of the Arc B390. The system's ranking is thus a direct consequence of the GPU dragging down the otherwise powerful CPU.

This ranking implies that for the specific workload of Pc Building Simulator, the CPU's massive computational lead is irrelevant. The AMD Ryzen 7 7700 sits in the 87th percentile of all CPUs, with an average benchmark score of 40081, but this power cannot be leveraged because the GPU cannot render frames fast enough to utilize it. The data shows that this combo is a classic case of a CPU bottleneck being reversed; here, the GPU is the strict limiting factor, and the system's rank accurately reflects its inability to deliver high frame rates.

GPU Role

The Intel Arc B390 is the clear performance anchor in this configuration. Its benchmark data shows a 3DMark Steel Nomad DX12 score of 1482, which is its only listed benchmark and places it in the 9th percentile of all GPUs. This score is within 2.7% of the NVIDIA GeForce GT 710, indicating that its raw performance is comparable to decade-old entry-level hardware, despite its 3 nm process node and Xe3-LPG architecture.

The GPU's memory configuration is described as "System Shared," with a base clock of 300 MHz and a boost clock of 2500 MHz. The shared memory and system-dependent bandwidth mean that the GPU relies on the system's DDR5 RAM, but the data suggests this is not a saving grace. The pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are incredibly low for a modern GPU, and these figures directly translate to the low FPS seen in the measured results. The FP32 performance of 7.680 TFLOPS is also modest, further explaining its poor gaming performance.

The GPU's TDP is 80 W and it is an IGP (Integrated Graphics Processor) with a slot width of "IGP," indicating it is built into the processor package. Despite its modern architecture and support for DirectX 12 Ultimate, the raw computational throughput is insufficient for 4K gaming at playable frame rates, as evidenced by the 20-21 FPS results at Ultra and High settings. The data shows that this GPU is not designed for high-end gaming, and its performance in this simulation reflects that.

Measured FPS Breakdown

At 1080p, the system's performance is the most varied, showing a clear scaling with settings. The Low preset yields an average of 125 FPS, which is the highest score recorded for this combo. Medium settings drop to 88 FPS, with a minimum of 75 and maximum of 102 FPS, while High achieves 62 FPS. Ultra settings are the most demanding, producing an average of 59 FPS, which is only marginally lower than High, suggesting a performance plateau.

Moving to 2560x1440, the frame rates drop significantly across all settings. Low settings produce 79 FPS, while Medium averages 56 FPS, with a minimum of 47 and maximum of 64 FPS. High settings achieve 39 FPS, and Ultra falls to 38 FPS. The data indicates a clear step-down from 1080p, with the GPU struggling to maintain 60 FPS on anything but the Low preset. This resolution is where the GPU's limitations become pronounced, as the pixel count increases by 78% from 1080p.

At 4K (3840x2160), the system is largely unplayable. Low settings yield an average of 41 FPS, which is a significant drop from 1080p. Medium settings average 29 FPS, with a minimum of 25 and maximum of 34 FPS. High settings drop to 21 FPS, and Ultra settings bottom out at 20 FPS. The data shows a clear linear decline with settings, and the frame rates are consistently below the threshold for a smooth gaming experience. The 4K results confirm that this combo is not suitable for high-resolution gaming, as even the lowest settings cannot maintain a stable 60 FPS.

CPU Role

The AMD Ryzen 7 7700 is an exceptionally capable processor, but its role in this combo is largely wasted. Its benchmark scores are impressive, with a Cinebench R23 multi-core score of 18760 and a single-core score of 1930. The Geekbench multi-core score of 15371 and single-core score of 2525 further demonstrate its strength. The CPU's 8 cores and 16 threads, based on the Zen 4 architecture, provide immense computational headroom that is not utilized in this gaming scenario.

The CPU's data shows it is in the 87th percentile of all CPUs, with an average benchmark score of 40081. Its nearest rivals, such as the AMD Ryzen AI 9 365 and Intel Core 5 221E, are within 0.4% of its score, indicating it is a top-tier performer. However, the measured FPS in Pc Building Simulator shows no benefit from this power. The 3DMark 16-thread score of 8484 and Passmark multi-thread score of 34470 are high, but the system's FPS is capped by the GPU's rendering speed.

The data implies that the CPU is never the bottleneck in this configuration. Even at 1080p Low settings, where the system achieves 125 FPS, the CPU is not being pushed to its limits. The CPU's boost clock of 5.30 GHz and 32 MB of L3 cache are more than sufficient to handle the simulation's logic, but the GPU's inability to render frames quickly enough means the CPU idles waiting for work. This is a classic example of a CPU with far more potential than the system can deliver, and the benchmark results confirm that the CPU's performance is not a limiting factor in this game. The CPU's 65 W TDP and 5 nm process node also suggest efficiency, but that efficiency is irrelevant when the GPU holds the system back.

Settings Recommendations

Based on the measured FPS data, the most balanced experience is found at the 1080p Medium preset. This setting yields an average of 88 FPS, with a minimum of 75 FPS and a maximum of 102 FPS, providing a smooth and responsive experience that stays above the 60 FPS threshold. The High preset at 1080p drops to 62 FPS, which is still playable but leaves less headroom for demanding scenes, while Ultra at 59 FPS is borderline.

For users with a 1440p monitor, the Low preset is the only viable option for a playable frame rate, averaging 79 FPS. The Medium preset at 1440p averages 56 FPS, which is below the 60 FPS target, and the High and Ultra presets at 39 and 38 FPS respectively are not recommended for a smooth experience. The data suggests that sacrificing visual quality is necessary to maintain performance at this resolution.

The 4K resolution is not recommended for this combo, as even the Low preset only achieves 41 FPS. The Medium, High, and Ultra presets at 4K produce 29, 21, and 20 FPS respectively, which are all well below the playability threshold. The data indicates that users should stick to 1080p for the best experience, with the Medium preset offering the best balance of visual fidelity and performance, as it is the only setting combination that consistently delivers frame rates above 75 FPS.
