Pc Building Simulator

Pc Building Simulator with an AMD Ryzen 7 5800XT and Intel Arc B390 produces a playable experience only at the lowest settings, with the integrated graphics acting as the primary constraint. The measured data shows a clear pattern: the combo ranks 2650 out of 3002 tested combinations, placing it in the bottom 12% of all systems, and the frame rates across all resolutions confirm that the GPU is the limiting factor.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and consistent across all settings, revealing that the Intel Arc B390’s integrated graphics are overwhelmed by pixel count. At Low settings, the average FPS falls from 125 at 1920x1080 to 79 at 2560x1440, a 37% reduction, and then to 41 at 3840x2160, a further 48% drop from 1440p. This scaling pattern is typical of a GPU-bound scenario: the CPU is not the bottleneck, and the workload scales almost linearly with the number of pixels rendered.

At Medium settings, the 1080p average of 88 FPS drops to 56 at 1440p (a 36% decline) and then to 29 at 4K (a 48% decline from 1440p). The High preset follows the same trend, with 62 FPS at 1080p falling to 39 at 1440p (37% lower) and 21 at 4K (46% lower). The Ultra preset starts at 59 FPS at 1080p, drops to 38 at 1440p (36% lower), and bottoms out at 20 FPS at 4K (47% lower). Across all four presets, the 1080p-to-1440p penalty is remarkably consistent at 36-37%, and the 1440p-to-4K penalty is similarly uniform at 46-48%. This uniformity indicates that the Arc B390's shading units, texture units, and ROPs are saturated at every quality level, and that resolution is the dominant variable.

The data suggests that the Ryzen 7 5800XT is not the limiting component. With 8 cores and 16 threads, the CPU has ample headroom for a simulation title, and the 3DMark single-thread score of 959 and 16-thread score of 7683 indicate strong compute capabilities. If the CPU were the bottleneck, we would expect to see diminishing returns as resolution increases, because higher resolutions shift the workload toward the GPU. Instead, the frame rate drops are proportional to the pixel count increase, which is the signature of a purely GPU-limited system. The Intel Arc B390, with its 1536 shading units and 24 ROPs, is simply not designed for 4K rendering, and even at 1440p, the frame rates are below the 60 FPS threshold for smooth gameplay at all settings except Low.

FAQ

Q: What is the average frame rate at 1080p with Medium settings?

A: The measured average FPS is 88, with a minimum of 75 and a maximum of 102. This is the highest resolution and setting combination that approaches a smooth experience, though it still falls short of a locked 60 FPS minimum.

Q: Can this combo handle 4K gaming?

A: No. At 4K, the average FPS is 41 at Low, 29 at Medium, 21 at High, and 20 at Ultra. Even the lowest preset fails to reach 60 FPS, and the Ultra preset is effectively unplayable with an average below 30 FPS.

Q: Is the CPU or GPU the bottleneck in this game?

A: The graphics card is the clear bottleneck. The frame rate drops by 36-37% from 1080p to 1440p and by another 46-48% from 1440p to 4K across all presets. This linear scaling with resolution indicates that the GPU is saturated, while the CPU's 8 cores and 16 threads provide more than enough processing power for the simulation workload.

Q: What is the best settings preset for a 60 FPS target?

A: At 1080p, only the Low preset (125 FPS average) exceeds 60 FPS. The Medium preset averages 88 FPS but has a minimum of 75, which is still above 60. At 1440p, the Low preset averages 79 FPS, while Medium drops to 56 FPS. For a consistent 60 FPS experience, 1080p Medium is the highest quality option, but 1440p Low is also viable.

CPU Role

The AMD Ryzen 7 5800XT is a Zen 3 (Vermeer) processor built on TSMC's 7 nm process, featuring 8 cores and 16 threads with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. It has a 32 MB shared L3 cache and 512 KB of L2 cache per core, along with 64 KB of L1 cache per core. The CPU supports DDR4 memory in a dual-channel configuration with a theoretical bandwidth of 51.2 GB/s, and it connects via PCIe Gen 4 with 20 lanes. Its 105 W TDP and unlocked multiplier make it a flexible desktop part, and its launch MSRP is $249.

In Pc Building Simulator, the CPU's role is largely secondary to the GPU. The game is a simulation title that manages system components, temperatures, and performance metrics, which can be CPU-intensive, but the measured frame rates show that the 5800XT is not the limiting factor. The 3DMark 16-thread score of 7683 and max-thread score of 7680 are nearly identical, indicating that the processor scales well with additional threads, and the Cinebench R23 multi-core score of 23794 demonstrates strong sustained performance. The single-thread score of 3359 in Cinebench R23 and 959 in 3DMark single-thread are also respectable, ensuring that the game's logic and UI updates are processed without stutter.

The nearest rival data shows that the 5800XT is in a tightly contested performance bracket. Its average benchmark score of 29879 is within 0.3% of the Ryzen 7 8845HS and 7840HS (both 29955) and essentially identical to the Ryzen 7 7840H (29868). It is 0.6% faster than the Ryzen 5 9600X (29713). This means that the CPU is not a weak link in the system; swapping it for a comparable processor would yield negligible gains in this game because the GPU is already maxed out. The PassMark multi-thread score of 28053 and single-thread score of 3535 further confirm that the CPU has ample headroom. The bottleneck is unequivocally the Intel Arc B390, which has a 3DMark Steel Nomad score of 1482, putting it in the 9th percentile of all GPUs.

Settings Recommendations

The measured data provides a clear hierarchy of settings for this combo, and the choice depends on the target resolution and acceptable frame rate. At 1920x1080, the Low preset delivers a 125 FPS average, which is the highest of any configuration tested, and even the Medium preset maintains an 88 FPS average with a minimum of 75 FPS. The High preset drops to 62 FPS average, and Ultra falls to 59 FPS, both of which are borderline for a smooth experience but lack the headroom of Medium. For a 1080p display, Medium is the recommended preset because it offers a substantial visual upgrade over Low while keeping the minimum FPS above 60.

At 2560x1440, the situation changes. The Low preset averages 79 FPS, which is above 60, but the Medium preset falls to 56 FPS average with a minimum of 47 FPS, which will result in noticeable stutter in demanding scenes. The High and Ultra presets are not viable at this resolution, with averages of 39 and 38 FPS respectively. For 1440p, the Low preset is the only option that provides a consistently smooth experience, and users should be prepared for lower visual fidelity.

At 3840x2160, no preset is recommended. The Low preset averages 41 FPS, which is below the playable threshold for most users, and the Medium preset (29 FPS), High (21 FPS), and Ultra (20 FPS) are all well below 30 FPS. The data indicates that this combo is not suitable for 4K gaming under any settings. The best overall experience is 1080p Medium, which balances visual quality with a 75 FPS minimum, or 1440p Low for users who prefer higher resolution over graphical detail. The Ultra preset at 1080p (59 FPS) is not worth the performance cost over High (62 FPS) because the difference is marginal and both fail to maintain a 60 FPS minimum.

How This Combo Ranks

The combination of the AMD Ryzen 7 5800XT and Intel Arc B390 ranks 2650 out of 3002 tested combos in Pc Building Simulator, placing it in the bottom 12% of all systems. This rank is driven almost entirely by the GPU's performance, as the CPU is in the 81st percentile of all processors while the GPU is in the 9th percentile. The disparity between these two components is stark: the 5800XT is a capable desktop processor that rivals mobile chips like the Ryzen 7 7840H (0% delta) and Ryzen 7 8845HS (-0.3% delta), but the Arc B390 is an integrated graphics solution that competes with decade-old discrete GPUs like the GeForce GT 520MX (1.3% delta) and GT 710 (2.7% delta).

This rank of 2650 means that 88% of tested combinations deliver higher frame rates in this game, and the only systems that perform worse are those with even older or more limited graphics hardware. The combo's position is not a reflection of the CPU's capabilities but rather a mismatch between the processor's high-end classification and the GPU's entry-level performance. In practical terms, the 5800XT is capable of driving much more powerful graphics cards, but in this configuration, it is held back by the Arc B390's limited shading units, texture units, and ROPs. The 3DMark Steel Nomad score of 1482 confirms that the GPU is the weak link, and any upgrade to a discrete graphics card would dramatically improve the combo's rank and playability.

Measured FPS Breakdown

The following are the exact measured average frame rates for each resolution and settings preset:

1920x1080:

• Low: 125 FPS average
• Medium: 88 FPS average (min 75, max 102)
• High: 62 FPS average
• Ultra: 59 FPS average

2560x1440:

• Low: 79 FPS average
• Medium: 56 FPS average (min 47, max 64)
• High: 39 FPS average
• Ultra: 38 FPS average

3840x2160:

• Low: 41 FPS average
• Medium: 29 FPS average (min 25, max 34)
• High: 21 FPS average
• Ultra: 20 FPS average

The data shows a consistent pattern across all presets: the step from Low to Medium costs approximately 30% of the frame rate at each resolution, while the step from Medium to High costs another 30%, and the step from High to Ultra is minimal (only 3-5 FPS). This suggests that the Low preset is the most efficient in terms of performance per visual quality, while the Ultra preset offers negligible improvements over High for a significant performance penalty. The minimum and maximum FPS values, where recorded, show that the Medium preset has a tighter frame time distribution, with a 27 FPS spread at 1080p (75-102) and a 17 FPS spread at 1440p (47-64), indicating less variance than the average suggests. At 4K Medium, the spread is 9 FPS (25-34), which is proportionally wider relative to the average, confirming that the GPU is struggling to maintain consistent frame pacing at higher resolutions.
