# Pc Building Simulator with AMD Ryzen 7 5800X + Intel Arc B390

The AMD Ryzen 7 5800X paired with the Intel Arc B390 delivers a fundamentally GPU-limited experience in Pc Building Simulator, with the combination ranking 2650th out of 3002 tested configurations. At 1080p Low settings the combo reaches 125 FPS, but the integrated-class GPU holds the system back at higher resolutions and quality presets, dropping to just 20 FPS at 4K Ultra. The Ryzen 7 5800X is a high-end CPU with an 81st percentile ranking among all processors, while the Arc B390 sits at the 9th percentile among GPUs — an extreme pairing that leaves massive CPU headroom unused in this simulation title.

FAQ

Q: How does the Intel Arc B390 compare to its nearest GPU rivals in benchmark scores?

A: The Arc B390 scores 1482 in the 3DMark Steel Nomad DX12 test. It sits 1.3% above the NVIDIA GeForce GT 520MX (1463), 1.5% above the GeForce 800M (1460), 2.5% above the GeForce GT 625 OEM (1446), and 2.7% above the GeForce GT 710 (1443). These are all extremely close scores, placing the B390 in the lowest performance tier of GPUs.

Q: What is the Ryzen 7 5800X's standing relative to other CPUs?

A: The CPU holds an 81st percentile ranking among all processors, with an average benchmark score of 29123. Its nearest rivals include the Intel Core Ultra 5 135H (29093, 0.1% behind), the Intel Xeon Phi 7210 (29245, 0.4% ahead), the Intel Core i5-13500HX (29270, 0.5% ahead), and the AMD Ryzen 5 5600XT (28940, 0.6% behind).

Q: What resolution and settings combo yields the highest average frame rate?

A: The 1920x1080 Low preset delivers the highest measured average at 125 FPS. The next best is 2560x1440 Low at 79 FPS, followed by 1920x1080 Medium at 88 FPS — note that the 1080p Medium actually outperforms the 1440p Low, indicating that resolution scaling has a steep impact on this GPU.

Q: Does the Arc B390 have dedicated VRAM, and how does that affect performance?

A: No, the Arc B390 uses System Shared memory, meaning its "memory size", "memory type", and "bus width" are all listed as "System Shared", with bandwidth described as "System Dependent". This shared-memory architecture is typical of integrated graphics and directly contributes to the GPU's low 9th percentile ranking.

Q: How does the combo rank among all tested configurations in Pc Building Simulator?

A: The combination ranks 2650th out of 3002 tested combos, placing it in the bottom 12% of all configurations. This low ranking is driven primarily by the GPU's weak benchmark results, not the CPU, which sits well above average.

Q: Is the CPU or GPU the limiting factor in this game?

A: The data clearly shows the GPU is the bottleneck. The Ryzen 7 5800X has a strong 3DMark 16-thread score of 7586 and a Cinebench R23 multi-core score of 15476, while the Arc B390's only benchmark is 1482 in 3DMark Steel Nomad. The FPS drop from 125 at 1080p Low to 41 at 4K Low (a 67% reduction) is consistent with GPU-bound scaling, not CPU limitations.

How This Combo Ranks

The combo ranks 2650th out of 3002 tested configurations in Pc Building Simulator, placing it in the lower 12% of all pairings tested. This is a decisive indicator that the combination is far below what most users would consider playable for a smooth experience in this title. The ranking reflects the dramatic mismatch between the CPU and GPU components: the Ryzen 7 5800X ranks in the 81st percentile of all CPUs with an average benchmark score of 29123, while the Arc B390 ranks in the 9th percentile of all GPUs with an average score of 1482.

This asymmetry means the system is entirely GPU-bound in this game. The CPU's nearest rivals — the Core Ultra 5 135H at 29093 (0.1% lower), the Xeon Phi 7210 at 29245 (0.4% higher), the Core i5-13500HX at 29270 (0.5% higher), and the Ryzen 5 5600XT at 28940 (0.6% lower) — all show that the 5800X sits in a tightly packed cluster near the top of the mid-range. In contrast, the Arc B390's rivals — GT 520MX, GeForce 800M, GT 625 OEM, and GT 710 — are all legacy or entry-level GPUs, confirming that the B390 belongs to a much lower performance tier.

The 2650th rank out of 3002 combos suggests that roughly 88% of tested configurations outperform this pairing. Given that the game is a simulation title that typically does not demand extreme hardware, this ranking indicates that the Arc B390 severely undermines what would otherwise be a capable system. The CPU alone could drive much higher frame rates, but it is held back by the GPU's inability to render frames quickly enough.

GPU Role

The Intel Arc B390 is the definitive bottleneck in this configuration. Its only benchmark result is a 3DMark Steel Nomad DX12 score of 1482, which places it at the 9th percentile of all GPUs. The nearest rivals are all at the very bottom of the GPU hierarchy: the GT 520MX (1463, 1.3% lower), the GeForce 800M (1460, 1.5% lower), the GT 625 OEM (1446, 2.5% lower), and the GT 710 (1443, 2.7% lower). These margins are exceedingly small, meaning the B390 is essentially at the floor of GPU performance.

The GPU's specifications confirm its integrated-class nature. It is built on Intel's 3 nm process with the Xe3-LPG architecture (Panther Lake chip) and operates at a base clock of 300 MHz with a boost clock of 2500 MHz. It has 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray-tracing cores, delivering a pixel rate of 60.00 GPixel/s, a texture rate of 120.0 GTexel/s, and 7.680 TFLOPS of FP32 compute. The TDP is 80 W, and it uses no power connectors, being an IGP (integrated graphics processor) with a bus interface of "IGP" and no dedicated memory — instead relying on System Shared memory with system-dependent bandwidth.

In Pc Building Simulator, the GPU's shared-memory architecture and low compute throughput manifest directly in the FPS numbers. At 1080p Low, the system manages 125 FPS, but this drops to 88 FPS at Medium, 62 FPS at High, and 59 FPS at Ultra. The scaling from Low to Ultra at 1080p shows a 53% performance reduction, which is substantial but not catastrophic at this resolution. However, at 4K, the GPU collapses: Ultra runs at 20 FPS, High at 21 FPS, Medium at 29 FPS, and even Low only reaches 41 FPS. This pattern is typical of a GPU that lacks both the memory bandwidth and the raw shading power to handle higher pixel counts.

Measured FPS Breakdown

The measured FPS data provides a complete picture across three resolutions and four quality presets. At 1920x1080, the combo delivers 125 FPS on Low, 88 FPS on Medium (with a min of 75 and max of 102), 62 FPS on High, and 59 FPS on Ultra. The 1080p results show that the system is playable at all settings, with even Ultra exceeding 60 FPS, though just barely.

Moving to 2560x1440, performance drops significantly. Low settings yield 79 FPS, Medium produces 56 FPS (with a min of 47 and max of 64), High falls to 39 FPS, and Ultra dips to 38 FPS. The 1440p Medium result of 56 FPS is the last playable tier, as High and Ultra both sit below 40 FPS. The gap between Low and Medium at 1440p is 23 FPS, while the gap between Medium and High is 17 FPS, indicating diminishing returns as quality increases.

At 3840x2160, the GPU is overwhelmed. Low settings achieve 41 FPS, Medium drops to 29 FPS (with a min of 25 and max of 34), High falls to 21 FPS, and Ultra bottoms out at 20 FPS. None of the 4K settings reach 60 FPS, and even Low is below the 45 FPS threshold typically considered minimally playable. The 4K Ultra result of 20 FPS is essentially a slideshow.

The resolution scaling tells the story clearly: from 1080p Low (125 FPS) to 1440p Low (79 FPS) is a 37% drop, and from 1440p Low to 4K Low (41 FPS) is another 48% drop. This compounding loss of performance with each resolution increase confirms that the Arc B390's shared-memory bandwidth and limited compute resources cannot keep up with higher pixel counts.

CPU Role

The AMD Ryzen 7 5800X is a high-end desktop processor that is severely underutilized in this configuration. It features 8 cores and 16 threads based on the Zen 3 architecture (codenamed Vermeer), with a base clock of 3.80 GHz and a boost clock of 4.70 GHz. The CPU has a 105 W TDP, supports DDR4 memory with dual-channel bandwidth of 51.2 GB/s, and includes 32 MB of L3 cache. It is built on TSMC's 7 nm process with 4,150 million transistors on a 74 mm² die.

The CPU's benchmark results are strong across the board. It scores 7586 in 3DMark 16-thread, 7578 in 3DMark max-threads, and 6035 in 3DMark 8-thread tests. In Cinebench R23, it achieves 15476 multi-core and 1574.5 single-core. Geekbench shows 11036 multi-core and 2032 single-core. Passmark results include 27732 multi-thread, 3445 single-thread, 94969 integer math, and 52639 floating point math. The 81st percentile ranking among all CPUs confirms its position well above the median.

In Pc Building Simulator, the CPU's role is to handle the simulation logic, which includes tracking PC components, managing the build process, and running diagnostics. The game's 2019 release date means it was designed for older hardware, and the Ryzen 7 5800X far exceeds those requirements. The FPS data shows no evidence of CPU limitation: the frame rates scale almost entirely with resolution and settings, which is the hallmark of a GPU-bound scenario. Even at 1080p Low, where the CPU would be most likely to become a factor, the system achieves 125 FPS, and the primary constraint is the Arc B390's rendering speed.

The CPU's nearest rivals — all scoring within 0.6% of each other — indicate that the 5800X is in a performance tier where small differences in synthetic benchmarks do not translate to meaningful gaming differences. The 5800X's 16 threads provide ample parallelism for any simulation workload, and its single-thread score of 943 in 3DMark and 1574.5 in Cinebench R23 ensure strong responsiveness in the game's UI and logic loops.

Settings Recommendations

For 1080p, the Ultra preset at 59 FPS is the best balance of visual quality and playability, though it does not quite hit 60 FPS. The High preset at 62 FPS achieves that target with marginally lower quality. Medium at 88 FPS offers a substantial frame rate buffer for smoother gameplay, while Low at 125 FPS is ideal for maximum responsiveness, though it sacrifices visual fidelity. Given that the difference between High and Ultra is only 3 FPS, Ultra is the recommended preset at 1080p for users prioritizing image quality, with High as a slightly more stable alternative.

At 1440p, the situation changes. Medium at 56 FPS is the only preset that maintains a playable frame rate, with a minimum of 47 FPS that stays above the 45 FPS threshold. High at 39 FPS and Ultra at 38 FPS are both below 40 FPS, which would result in noticeable stutter in a simulation game. Low at 79 FPS is the smoothest option but visually sparse. The recommendation is Medium for 1440p, as it provides the best compromise between visual quality and consistent performance.

At 4K, none of the presets deliver a satisfactory experience. Medium at 29 FPS (with a min of 25) is the highest average, but it falls well short of smooth gameplay. Low at 41 FPS is the only preset that approaches playability, though it still exhibits noticeable frame pacing issues. High at 21 FPS and Ultra at 20 FPS are effectively unplayable. For 4K users, the recommendation is to use Low settings and accept the 41 FPS average, or ideally, to lower the resolution to 1440p Medium for a much better experience.

Overall, the best experience per the measured rows is 1920x1080 Ultra at 59 FPS, which delivers near-maximum visual quality at a playable frame rate. Users with 1440p monitors should select Medium for 56 FPS. Those with 4K displays should consider 1440p Medium instead, as the 4K Low result of 41 FPS is the only viable option at that resolution, and it still falls below the 60 FPS target.
