# Pc Building Simulator Performance Analysis: Intel Core Ultra 7 265K + Intel Arc B390

This combination of Intel's Core Ultra 7 265K processor and the integrated Arc B390 graphics solution delivers playable frame rates in Pc Building Simulator, though the data reveals a system heavily constrained by its graphics subsystem. The measured results across three resolutions and four quality presets show a clear pattern: the CPU has ample headroom while the GPU becomes the limiting factor as resolution and settings increase. The benchmark data positions this combo at rank 2650 out of 3002 tested combinations, placing it in the lower quartile of system performance for this title.

Settings Recommendations

The measured FPS data provides a clear hierarchy of playable configurations. At 1920x1080, the Low preset delivers an average of 125 FPS, which is more than double the 62 FPS observed at High settings. The Medium preset at 1080p produces 88 FPS average with a minimum of 75 FPS and maximum of 102 FPS, offering a balanced experience. For users prioritizing smoothness over visual fidelity, Low at 1080p is the clear choice, as it maintains well above 100 FPS average.

Moving to 2560x1440, the Low preset still manages a respectable 79 FPS average, while Medium drops to 56 FPS with a minimum of 47 FPS. At this resolution, High settings yield 39 FPS and Ultra falls to 38 FPS, both below the 60 FPS threshold that many simulation games benefit from. The data suggests that 1440p users should stick with Low or Medium presets, as the jump to High costs 17 FPS on average compared to Medium.

At 3840x2160, the situation becomes more constrained. Low settings produce 41 FPS average, Medium drops to 29 FPS with a minimum of 25 FPS, High manages only 21 FPS, and Ultra bottoms out at 20 FPS. None of the 4K presets reach 60 FPS average, meaning users at this resolution must accept sub-60 performance regardless of settings. The best experience at 4K is Low, which provides 41 FPS average, roughly double the Ultra preset's 20 FPS.

Considering the measured data across all resolutions, the optimal experience balances frame rate and visual quality. At 1080p, Medium offers the best compromise with 88 FPS average and a minimum of 75 FPS, staying comfortably above 60 FPS. At 1440p, Low is the recommended preset at 79 FPS average, as Medium's 56 FPS average approaches the 60 FPS threshold but doesn't consistently exceed it. For 4K, users must accept Low at 41 FPS average as the most playable option, since all other presets fall below 30 FPS.

GPU Role

The Intel Arc B390 is an integrated graphics solution based on the Xe3-LPG architecture, manufactured on Intel's 3 nm process. Its clock speeds range from a 300 MHz base to a 2500 MHz boost, and it operates with system-shared memory, meaning the memory bus width, bandwidth, and capacity are all dependent on the host system's configuration. The GPU features 1536 shading units, 48 texture mapping units, and 24 raster output pipelines, along with 12 ray tracing cores. Its compute capabilities include 7.680 TFLOPS for FP32 operations and 15.36 TFLOPS for FP16 with a 2:1 ratio.

In the context of Pc Building Simulator, the GPU's performance is the dominant constraint. The 3DMark Steel Nomad DX12 benchmark score of 1482 places this GPU at the 9th percentile among all GPUs, indicating entry-level performance. Its nearest rivals in benchmark scores are the NVIDIA GeForce GT 520MX at 1463 (1.3% difference), GeForce 800M at 1460 (1.5% difference), GT 625 OEM at 1446 (2.5% difference), and GT 710 at 1443 (2.7% difference). This positioning explains why the combo ranks so low in Pc Building Simulator — the GPU's raw performance is comparable to decade-old discrete graphics solutions.

The GPU's 80 W TDP and IGP slot width indicate it's designed for power efficiency rather than high performance. The system-shared memory architecture means there's no dedicated VRAM; instead, the GPU borrows from system memory, which can introduce latency and bandwidth limitations. This is particularly evident at higher resolutions where memory bandwidth demands increase. The pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are modest figures that align with the observed frame rates in this simulation title.

How This Combo Ranks

The Intel Core Ultra 7 265K paired with the Intel Arc B390 achieves combo rank 2650 out of 3002 tested combinations in Pc Building Simulator. This places the system in the 88th percentile from the bottom, meaning roughly 88% of tested configurations outperform it. The ranking reflects the significant bottleneck created by the integrated GPU, despite the CPU's strong benchmark scores.

The CPU alone performs admirably in synthetic benchmarks. Its average benchmark score of 70879 places it at the 94th percentile among all CPUs. In Cinebench R23, it scores 35850 in multi-core and 2020 in single-core tests. Geekbench results show 23085 multi-core and 2713 single-core scores. The nearest CPU rivals include the Intel Xeon 6511P with an average score of 71051 (-0.2% delta), Intel Xeon Platinum 8270 at 71370 (-0.7% delta), Intel Core i7-14700KF at 70163 (+1% delta), and AMD Ryzen 7 9700F at 69996 (+1.3% delta). These rival comparisons demonstrate that the CPU is competitive with high-end workstation and desktop processors.

However, the GPU's 9th percentile ranking among all GPUs drags the overall combo performance down dramatically. The 3DMark Steel Nomad score of 1482 is exceptionally low, and the nearest GPU rivals are all from the GeForce 600 series or older mobile chips. This extreme disparity between CPU and GPU performance is the defining characteristic of this combo — the processor has substantial headroom while the graphics solution limits every gaming workload. In Pc Building Simulator specifically, the measured FPS data confirms that the GPU is the primary constraint at all resolutions and settings.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values span from 125 at Low settings down to 59 at Ultra. The Low preset delivers 125 FPS average, which is the highest measured value across all configurations. Medium produces 88 FPS with a minimum of 75 FPS and maximum of 102 FPS, providing a narrow band of performance. High settings yield 62 FPS average, while Ultra drops to 59 FPS average. The gap between Low and Medium is 37 FPS, while the gap between High and Ultra is only 3 FPS, suggesting diminishing returns as settings increase.

At 2560x1440, the average FPS values show a similar pattern but with lower overall numbers. Low settings deliver 79 FPS average, Medium achieves 56 FPS with a minimum of 47 FPS and maximum of 64 FPS, High produces 39 FPS, and Ultra manages 38 FPS. The difference between Low and Medium is 23 FPS, while High and Ultra are nearly identical at 39 and 38 FPS respectively. The minimum FPS of 47 at Medium indicates that even this preset can dip below 60 FPS during demanding scenes.

At 3840x2160, performance drops significantly across all settings. Low settings produce 41 FPS average, which is the only preset above 30 FPS. Medium delivers 29 FPS with a minimum of 25 FPS and maximum of 34 FPS, High yields 21 FPS, and Ultra bottoms out at 20 FPS. The gap between Low and Medium is 12 FPS, while High and Ultra are essentially tied at 21 and 20 FPS. This resolution shows the most severe performance degradation, with all presets except Low falling below playable thresholds.

Comparing across resolutions at the same settings reveals the GPU's limitations. At Low settings, 1080p produces 125 FPS, 1440p produces 79 FPS, and 4K produces 41 FPS. At Medium settings, the values are 88, 56, and 29 FPS respectively. At High settings, they are 62, 39, and 21 FPS. At Ultra settings, they are 59, 38, and 20 FPS. The consistent pattern shows that each resolution step roughly halves the frame rate, indicating a purely GPU-bound scenario.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and reveals the limiting component. At Low settings, moving from 1080p to 1440p reduces average FPS from 125 to 79, a 46 FPS decrease (37%). Moving from 1440p to 4K reduces it further to 41 FPS, another 38 FPS decrease (48%). The total drop from 1080p to 4K at Low settings is 84 FPS, representing a 67% reduction.

At Medium settings, the scaling follows a similar pattern. From 1080p to 1440p, FPS drops from 88 to 56, a 32 FPS decrease (36%). From 1440p to 4K, it drops from 56 to 29, a 27 FPS decrease (48%). The total reduction from 1080p to 4K at Medium is 59 FPS, or 67% of the original value.

High settings show the same relative scaling. From 1080p to 1440p, FPS drops from 62 to 39, a 23 FPS decrease (37%). From 1440p to 4K, it drops from 39 to 21, an 18 FPS decrease (46%). The total reduction is 41 FPS, or 66%. Ultra settings follow suit with drops from 59 to 38 (36%) and then to 20 (47%), totaling 39 FPS or 66% reduction.

This consistent ~66-67% reduction from 1080p to 4K across all settings indicates that the GPU is the bottleneck. A CPU-bound scenario would show less degradation at higher resolutions because the CPU workload doesn't scale linearly with pixel count. The fact that every preset shows nearly identical percentage drops confirms that the Intel Arc B390's rendering throughput is the limiting factor. The system-shared memory architecture likely exacerbates this, as higher resolutions require more memory bandwidth for frame buffers, which competes with system memory traffic.
