Pc Building Simulator

Resolution Scaling

Pc Building Simulator presents an unusual scaling pattern with this AMD Ryzen 5 5500 + Intel Arc B390 combination. Moving from 1920x1080 to 2560x1440 at High settings drops average FPS from 62 to 39, a 37% reduction. The further step to 3840x2160 at High settings brings average FPS down to 21, which is another 46% drop from the 1440p figure. This consistent halving of performance with each resolution increase points strongly to the GPU being the limiting factor.

At Low settings, the scaling story becomes more revealing. The 1080p result shows 125 FPS average, which drops to 79 FPS at 1440p and then to 41 FPS at 4K. The percentage losses are 37% and 48% respectively. The fact that even the lowest settings cannot maintain playable frame rates at 4K indicates that the Intel Arc B390's rendering capabilities are being exhausted, not the CPU or memory bandwidth.

Ultra settings tell a similar tale. The 1080p average of 59 FPS falls to 38 FPS at 1440p, and then to 20 FPS at 4K. Medium settings show 88 FPS at 1080p, 56 FPS at 1440p, and 29 FPS at 4K. Across every settings tier, the resolution scaling pattern remains consistent — approximately 55-65% of the previous resolution's performance. This uniformity suggests that the bottleneck is almost entirely graphical in nature.

The measured FPS data indicates that Pc Building Simulator's rendering load scales nearly linearly with pixel count. When pixel count roughly doubles from 1080p to 1440p, the FPS drops to roughly 60% of the original value. When pixel count doubles again to 4K, the same proportional loss occurs. This behavior is characteristic of a fill-rate limited scenario, where the GPU's pixel throughput and memory bandwidth are the decisive factors.

For this specific combination, 1080p is the only resolution where the system can approach smooth gameplay, and even then only at Low or Medium settings. The 4K results, with averages ranging from 20 to 41 FPS depending on settings, confirm that this resolution is not viable for this pairing. The data suggests that any attempt to play at 4K will result in a slideshow-like experience regardless of how far the settings are lowered.

GPU Role

The Intel Arc B390 is an integrated graphics processor based on the Xe3-LPG architecture, built on Intel's 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz. The GPU has 1536 shading units, 48 texture mapping units, and 24 render output units, along with 12 ray tracing cores. Its compute capabilities are rated at 7.680 TFLOPS for FP32 and 15.36 TFLOPS for FP16.

The most distinctive aspect of this GPU is its memory configuration. The B390 uses System Shared memory, meaning it has no dedicated VRAM of its own. The memory type, bus width, and bandwidth are all listed as "System Shared" or "System Dependent". This means the GPU relies entirely on the system's DDR4 memory, which the Ryzen 5 5500 supports in dual-channel configuration with a memory bandwidth of 51.2 GB/s.

This shared memory architecture has direct implications for Pc Building Simulator's performance. The game's simulation nature means it stores a substantial amount of state data, and the GPU must access this through the system memory bus. At higher resolutions, the increased pixel count demands more memory traffic, and the shared memory arrangement becomes a serious constraint. The 4K High setting result of 21 FPS average illustrates this limitation clearly.

The GPU's benchmark scores reinforce this interpretation. The 3DMark Steel Nomad DX12 score is 1482, which places the B390 in the 9th percentile of all GPUs. Its nearest rivals are the NVIDIA GeForce GT 520MX, GeForce 800M, GT 625 OEM, and GT 710, with delta percentages of 1.3%, 1.5%, 2.5%, and 2.7% respectively. These are all entry-level or legacy graphics solutions, which contextualizes why Pc Building Simulator struggles at higher resolutions.

The pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s provide theoretical limits that the measured FPS data reflects. At 4K, the pixel throughput requirement is substantial, and the B390's fill rate is insufficient to maintain adequate frame rates. The GPU's 80 W TDP and integrated form factor (labeled as IGP) further indicate that this is not designed for demanding graphical workloads.

Measured FPS Breakdown

At 1920x1080, the system delivers its strongest results. Low settings produce an average of 125 FPS, which is the highest measured value in the entire dataset. Medium settings yield 88 FPS average with a minimum of 75 FPS and maximum of 102 FPS. High settings drop to 62 FPS average, while Ultra settings produce 59 FPS average. The range from Low to Ultra spans 66 FPS, indicating that settings have a significant impact at this resolution.

Moving to 2560x1440, the performance profile shifts downward. Low settings still manage a respectable 79 FPS average. Medium settings produce 56 FPS average with a minimum of 47 FPS and maximum of 64 FPS. High settings fall to 39 FPS average, and Ultra settings produce 38 FPS average. The difference between High and Ultra narrows considerably at this resolution, suggesting that the GPU's capabilities are being saturated.

At 3840x2160, the system struggles across all settings. Low settings produce 41 FPS average, which is the only double-digit result at this resolution. Medium settings yield 29 FPS average with a minimum of 25 FPS and maximum of 34 FPS. High settings drop to 21 FPS average, and Ultra settings produce 20 FPS average. The gap between Low and Ultra is only 21 FPS, demonstrating that settings adjustments have diminishing returns at 4K.

The Medium settings rows are the only ones that include minimum and maximum FPS data. At 1080p Medium, the frame time variation is from 75 to 102 FPS, a spread of 27 FPS. At 1440p Medium, the spread narrows to 17 FPS (47 to 64). At 4K Medium, the spread is just 9 FPS (25 to 34). This tightening of the frame rate range at higher resolutions indicates that the system becomes more consistently GPU-bound as pixel count increases.

CPU Role

The AMD Ryzen 5 5500 is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Cezanne. It has a base clock of 3.60 GHz and a boost clock of 4.20 GHz, with a 65 W TDP. The processor features 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 16 MB of L3 cache. It supports DDR4 memory in dual-channel configuration with a memory bandwidth of 51.2 GB/s.

In Pc Building Simulator, the CPU's role appears secondary to the GPU's limitations. The game is a simulation title, which typically benefits from strong single-thread performance. The Ryzen 5 5500's Cinebench R23 single-core score of 2319 and multicore score of 16429 indicate solid processing capability. Its PassMark single-thread score of 3058 and multithread score of 19330 further confirm this.

The CPU's benchmark scores place it in the 73rd percentile of all processors, with an average benchmark score of 19593. Its nearest rivals include the AMD Ryzen AI 5 430 (delta -0.1%), Intel Core i5-12500 (delta -0.4%), Intel Core i7-10700F (delta +0.5%), and Intel Core i5-11600KF (delta -0.7%). These deltas are all within 1%, indicating that the Ryzen 5 5500 performs on par with these alternatives.

The 3DMark thread scaling scores provide additional context. The processor scores 836 in single-thread, 1645 in 2-thread, 3151 in 4-thread, 4593 in 8-thread, and 5411 in max-thread tests. The scaling from 8-thread to max-thread (5411 versus 4593) shows a modest 18% improvement, suggesting diminishing returns beyond 8 threads for this processor.

Given that Pc Building Simulator's frame rates scale consistently with resolution changes, the CPU is not the primary constraint. If the Ryzen 5 5500 were the bottleneck, we would expect to see FPS plateaus at lower resolutions where the GPU has spare capacity. Instead, the 1080p Low result of 125 FPS suggests the CPU can feed the GPU adequately, and the performance ceiling is set by the B390's capabilities.

Settings Recommendations

Based on the measured FPS data, the optimal configuration for this combination depends heavily on the target resolution. At 1920x1080, Medium settings provide the best balance with an 88 FPS average and a minimum of 75 FPS. This configuration stays above the 60 FPS threshold while leaving headroom for frame time spikes. The jump from Medium to High costs 26 FPS (from 88 to 62), which is a substantial penalty for modest visual gains.

At 2560x1440, Low settings are the only configuration that maintains playable frame rates, with a 79 FPS average. Medium settings drop to 56 FPS, which may be acceptable for a simulation title but does not provide a consistent 60 FPS experience. The difference between High (39 FPS) and Ultra (38 FPS) at this resolution is negligible, indicating that the GPU is already saturated.

At 3840x2160, no settings configuration delivers playable performance. The best result is 41 FPS at Low settings, which falls below the 60 FPS threshold. Medium, High, and Ultra settings produce 29, 21, and 20 FPS respectively. Users targeting 4K would need to consider a different GPU, as the B390's integrated architecture cannot handle this resolution in Pc Building Simulator.

The Ultra preset consistently delivers the lowest performance at every resolution, with only 59 FPS at 1080p being the sole instance where it exceeds 40 FPS. The High preset offers marginal improvements over Ultra at 1080p (62 versus 59 FPS) and 1440p (39 versus 38 FPS), but the difference widens at 4K (21 versus 20 FPS). The Low preset provides the largest performance headroom, especially at lower resolutions where the CPU can still push high frame rates.

For the best experience, 1080p Medium is the recommended configuration. It offers 88 FPS average with a minimum of 75 FPS, which provides smooth gameplay while maintaining visual quality. Users who prioritize frame rate over visuals can opt for 1080p Low at 125 FPS, while those who want maximum fidelity can try 1080p Ultra at 59 FPS, though this approaches the edge of acceptable smoothness.

How This Combo Ranks

The AMD Ryzen 5 5500 + Intel Arc B390 combination ranks 2650 out of 3002 tested combos in Pc Building Simulator. This places the pairing in the bottom 12% of all tested configurations, reflecting the GPU's limited gaming capabilities. The rank is more a function of the B390's performance than the Ryzen 5 5500, given that the CPU's benchmark scores are respectable.

The GPU's percentile ranking of 9 places it in the bottom decile of all GPUs, and its nearest rivals are all legacy or entry-level NVIDIA parts. This explains why the combo ranks so poorly despite having a capable CPU. The system's performance in Pc Building Simulator is constrained by the integrated graphics solution, which cannot handle the game's rendering requirements at higher resolutions.

The combination's rank is further contextualized by the CPU's performance tier. The Ryzen 5 5500 sits in the 73rd percentile of all CPUs, with an average benchmark score of 19593. Its nearest rivals are all within 1% of its performance, including the Ryzen AI 5 430, Core i5-12500, Core i7-10700F, and Core i5-11600KF. This indicates that the CPU is not the limiting factor in this pairing.

In practical terms, this rank means that most other tested combinations will outperform this setup in Pc Building Simulator. The combo's 2650th place out of 3002 suggests that users with this hardware should expect below-average performance compared to the broader benchmark database. The measured FPS data confirms this: even at 1080p Low settings, the 125 FPS result is respectable, but the system's inability to maintain playable frame rates at 1440p and 4K places it firmly in the lower tier of tested configurations.

For users considering this hardware, the data indicates that Pc Building Simulator can be played at 1080p with reasonable settings, but the experience will be limited compared to systems with dedicated graphics cards. The combination's rank reflects this reality, positioning it as a low-end solution for this particular simulation title.
