Q: How much faster is the Low preset compared to Ultra?

A: At 1920x1080, Low averages 125 FPS versus 59 FPS on Ultra, a 112 percent increase in frame rate. At 2560x1440, Low hits 79 FPS compared to Ultra's 38 FPS, a 108 percent improvement. At 3840x2160, Low reaches 41 FPS versus Ultra's 20 FPS, a 105 percent gain. The relative scaling is consistent across resolutions.

Q: Is this combo viable for competitive play?

A: Only at 1920x1080 with Low settings, where it hits 125 FPS. Medium at 1080p yields 88 FPS, which is acceptable for most players. Any higher resolution or preset drops below 80 FPS, making it unsuitable for fast-paced competitive scenarios that benefit from high refresh rates.

Settings Recommendations

The measured data indicates that 1920x1080 with Medium settings offers the best balance of visual quality and performance for this combo. At this configuration, the system delivers an average of 88 FPS with a minimum of 75 FPS and a maximum of 102 FPS. This provides a stable experience above the 60 FPS threshold while retaining some graphical fidelity beyond the lowest preset.

For players prioritizing frame rate above all else, 1920x1080 Low achieves 125 FPS, which is the only measured configuration to exceed 120 FPS. This setting is recommended for competitive play or for users with high-refresh-rate monitors. The jump from Low to Medium costs 37 FPS (from 125 to 88), which is a substantial trade-off for modest visual gains in a simulation title.

At 2560x1440, the Medium preset is the highest playable option, averaging 56 FPS with a minimum of 47 FPS. This is borderline for smooth gameplay, so users with 1440p monitors should stick to Low (79 FPS) for a more consistent experience. High and Ultra at this resolution drop to 39 FPS and 38 FPS respectively, which are not recommended.

The 3840x2160 resolution is effectively unusable for this game with this hardware. Even the Low preset only manages 41 FPS, and Medium falls to 29 FPS with minimums of 25 FPS. Ultra at 4K averages just 20 FPS. Users should avoid 4K entirely unless they accept slideshow-like frame rates.

How This Combo Ranks

This specific combination of AMD Ryzen 7 5700X3D and Intel Arc B390 ranks 2650th out of 3002 tested combos in Pc Building Simulator. This places it in the bottom 11.7 percent of all systems tested, confirming that this pairing is far below average for this game. The ranking reflects the GPU's severe performance limitation rather than any CPU deficiency.

The CPU alone sits in the 77th percentile among all processors, indicating strong processing capability that is wasted in this pairing. The GPU, by contrast, ranks in the 9th percentile, creating a massive imbalance. The combo rank of 2650/3002 is much closer to the GPU's percentile than the CPU's, which demonstrates how heavily the graphics card dictates the final outcome in this game.

Compared to the nearest rival GPUs, the Arc B390's 1482 Steel Nomad score is only 1.3 percent higher than the GT 520MX and 2.7 percent higher than the GT 710. These are all legacy or entry-level parts, and the performance delta between them is negligible. This suggests that the combo's low rank is not an anomaly but rather a consistent result for this class of GPU.

The rank disparity between the CPU and GPU creates a situation where upgrading the graphics card alone would yield dramatic improvements, while replacing the CPU would produce minimal gains. The data indicates that the Ryzen 7 5700X3D has substantial headroom that the Arc B390 cannot utilize. This is a textbook case of a CPU far outpacing its GPU partner.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. The Low preset averages 125 FPS, which is the highest measured frame rate across all resolutions and settings. Medium drops to 88 FPS with a minimum of 75 FPS and a maximum of 102 FPS. High averages 62 FPS, while Ultra falls to 59 FPS. The step from Medium to High costs 26 FPS, and the step from High to Ultra costs only 3 FPS, suggesting diminishing returns at the top end.

Moving to 2560x1440, performance drops by roughly 37 percent across all settings. Low averages 79 FPS, Medium averages 56 FPS with a minimum of 47 FPS and a maximum of 64 FPS, High averages 39 FPS, and Ultra averages 38 FPS. The difference between High and Ultra narrows to just 1 FPS at this resolution, indicating that the GPU has hit a hard performance wall.

At 3840x2160, the results are mostly below playable thresholds. Low averages 41 FPS, Medium averages 29 FPS with a minimum of 25 FPS and a maximum of 34 FPS, High averages 21 FPS, and Ultra averages 20 FPS. The scaling from Low to Medium is a 12 FPS drop, and from Medium to High is an 8 FPS drop, with High to Ultra costing only 1 FPS. The minimum frame rates at Medium (25 FPS) suggest noticeable stutter during busy scenes.

The resolution scaling is consistent: 4K performance is roughly half of 1440p, which is roughly half of 1080p. This linear scaling is typical of a GPU-bound scenario where pixel throughput is the limiting factor. The CPU's strong single-thread score (3157 in Cinebench R23) does not help at higher resolutions because the GPU cannot process frames fast enough to utilize the CPU's headroom.

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 uses system shared memory, meaning its memory bandwidth is dependent on the system's RAM configuration. The GPU has 1536 shading units, 48 texture mapping units, and 24 raster output units, along with 12 ray tracing cores. Its boost clock reaches 2500 MHz, and it has a TDP of 80 W.

The GPU's 3DMark Steel Nomad DX12 score of 1482 places it in the 9th percentile of all GPUs. This is a very low score, putting it in the same performance class as the NVIDIA GeForce GT 520MX and GT 710. The pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are modest figures that directly explain why the GPU struggles at higher resolutions.

The fact that this GPU uses system shared memory is critical. In Pc Building Simulator, which involves managing system components, the shared memory architecture means the GPU competes with the CPU for memory bandwidth. This is reflected in the steep frame rate drops when moving from 1080p to 1440p and 4K, as the memory subsystem becomes a bottleneck.

The GPU's DirectX 12 Ultimate support (12_2) and Vulkan 1.4 API compatibility are modern, but the raw compute power (7.680 TFLOPS FP32) is insufficient for high-fidelity gaming. The measured data shows that even at 1080p, the Ultra preset only achieves 59 FPS, indicating that the GPU is near its absolute limit for this game. The 12 ray tracing cores are present but underpowered, though Pc Building Simulator likely does not rely heavily on ray tracing.

CPU Role

The AMD Ryzen 7 5700X3D is an 8-core, 16-thread processor based on the Zen 3 architecture, codenamed Vermeer. It has a base clock of 3.00 GHz and a boost clock of 4.10 GHz, with a TDP of 105 W. The CPU includes a large 96 MB shared L3 cache, which is a defining feature of the X3D series. It supports DDR4 memory with a dual-channel bus and 51.2 GB/s bandwidth.

In synthetic benchmarks, this CPU performs strongly. It scores 22366 in Cinebench R23 multi-core and 3157 in single-core, with a Geekbench multi-core score of 11086 and single-core score of 1849. The PassMark multithread score is 26318, and the 3DMark 16-thread score is 6764. These results place it in the 77th percentile of all CPUs, just behind the AMD Ryzen 5 7600X3D and AMD Ryzen 9 5900HX by less than 0.5 percent.

For Pc Building Simulator, the CPU's 8 cores and 16 threads are more than sufficient. The game is a simulation title that likely benefits from the large L3 cache, which reduces memory latency for frequently accessed data. The CPU's strong multi-threaded performance means it can handle background simulation tasks without impacting frame rates, but the measured FPS data shows that the GPU is the limiting factor.

The CPU's 96 MB L3 cache is particularly relevant for this game, as simulation titles often have large working sets that benefit from cache hits. However, the benchmark results indicate that even with this advantage, the system cannot overcome the GPU's limitations. The CPU's nearest rivals all score within 0.6 percent, confirming that any of these processors would perform nearly identically in this pairing. The CPU is not the problem here.
