Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data for Pc Building Simulator reveals a dramatic scaling pattern as resolution increases. At 1080p with Low settings, this combo delivers 125 FPS, which drops to 79 FPS at 1440p and further to 41 FPS at 4K. That represents a 67% reduction from 1080p to 4K at Low settings — a steep decline that points directly at the GPU as the primary bottleneck.

Looking at High settings, the scaling is even more telling. The system produces 62 FPS at 1080p, 39 FPS at 1440p, and just 21 FPS at 4K. The 4K figure is only 34% of the 1080p performance. This is a classic signature of a graphics-bound scenario, where the Intel Arc B390's limited pixel throughput (60.00 GPixel/s) becomes the ceiling.

The Medium settings row provides the only complete min/max data in the entire measurement set. At 1080p Medium, the average is 88 FPS with a range of 75 to 102 FPS. Moving to 1440p Medium drops the average to 56 FPS (range 47–64), and at 4K Medium it falls to 29 FPS (range 25–34). The consistent narrowing of the min-max gap at higher resolutions — from 27 FPS spread at 1080p down to 9 FPS at 4K — suggests the frame pacing becomes more uniform when the GPU is saturated.

The CPU, an AMD Ryzen 7 7700X, is unlikely to be the limiting factor here. Its benchmark results show strong multi-threaded capability, with a Cinebench R23 multicore score of 19088 and a Passmark multithread score of 35686. Even at 1080p, where CPU load typically matters most, the 125 FPS Low result suggests the processor is keeping pace without breaking a sweat. If the CPU were the constraint, we would expect to see less severe FPS drops when moving from 1080p to 1440p, since resolution scaling would have a muted effect.

The data implies that players wanting higher frame rates should focus on reducing graphical settings rather than upgrading the processor. The jump from Ultra to Low at any given resolution yields roughly double the FPS — at 1080p, Ultra produces 59 FPS while Low produces 125 FPS, a 112% improvement. This is a strong indicator that the Arc B390's rendering capabilities, not the Ryzen 7 7700X's processing power, dictate performance in this simulation title.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 7700X brings substantial processing resources to this pairing. With 8 cores and 16 threads based on the Zen 4 architecture (codenamed Raphael), it operates on a 5 nm process from TSMC. The base clock of 4.50 GHz can boost up to 5.40 GHz, which gives it strong single-threaded performance — a key attribute for simulation games that often rely on a primary game thread.

Benchmark data confirms this processor's capabilities. The 3DMark single-thread score of 1090 and Passmark single-thread score of 4190 indicate robust per-core performance. The Cinebench R15 single-core result of 315 reinforces this picture. For a game like Pc Building Simulator, which simulates component interactions and system building logic, these single-threaded strengths likely help maintain consistent frame delivery even when the GPU is the overall bottleneck.

Multi-threaded performance is equally impressive. The 3DMark max-threads score of 8852 nearly matches the 16-thread score of 8859, suggesting the CPU scales well across its full thread complement. The Cinebench R23 multicore score of 19088 places this chip in the 85th percentile of all CPUs tested, according to the benchmark database. Its average benchmark score of 35909 sits just 0.3% above the AMD Ryzen 7 PRO 5845, its closest rival in the data.

The L3 cache configuration — 32 MB shared across all cores — is worth noting. Each core also gets 64 KB of L1 and 1 MB of L2 cache. For a simulation game that may repeatedly access the same building components and system state data, this cache hierarchy could reduce memory latency and improve frame consistency. The CPU's memory bandwidth of 83.2 GB/s over DDR5 dual-channel support provides ample data throughput for game logic.

However, the measured FPS data does not suggest the CPU is holding this combo back. At 1080p Low, the 125 FPS result is well within what this processor can feed. Even at 1080p Ultra, the 59 FPS figure is more consistent with GPU limitation than CPU constraint. The Ryzen 7 7700X's role here appears to be providing headroom — it is capable of supporting higher frame rates than the Arc B390 can deliver, particularly at higher resolutions.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific pairing of AMD Ryzen 7 7700X and Intel Arc B390 ranks 2650 out of 3002 tested combos in Pc Building Simulator. That places it in the bottom 12% of all configurations tested, which is a striking result given the CPU's strong benchmark profile. The ranking suggests that the GPU is the determining factor in this combo's overall standing, since the Arc B390's average benchmark score of 1482 places it in just the 9th percentile of all GPUs.

The GPU's nearest rivals in the benchmark database are notably older, lower-performance parts. The NVIDIA GeForce GT 520MX scores 1463 (1.3% lower), the GeForce 800M scores 1460 (1.5% lower), the GT 625 OEM scores 1446 (2.5% lower), and the GT 710 scores 1443 (2.7% lower). These are all integrated or entry-level discrete GPUs from previous generations, which contextualizes the Arc B390's position. It is competing at the very bottom of the GPU performance spectrum.

The combo's rank of 2650 means 352 other tested combinations performed worse in this game. This is a meaningful distinction — the system is not the worst, but it sits far from the middle of the pack. Given that the Ryzen 7 7700X ranks in the 85th percentile of CPUs, the pairing represents a significant imbalance: a high-performing processor matched with a very low-performing graphics solution.

For Pc Building Simulator specifically, the game's modest graphical demands are evident from the fact that this low-end GPU can still produce playable frame rates at 1080p with lower settings. The 125 FPS at 1080p Low demonstrates that the game is not particularly demanding, yet the combo still ranks poorly because other tested configurations presumably use more balanced or higher-end GPU pairings. The data suggests that in a game about building PCs, this particular build would be considered heavily skewed toward CPU investment.

A: The 4K Ultra average of 20 FPS, combined with the GPU's 60.00 GPixel/s pixel rate and 7.680 TFLOPS FP32 performance, shows that the Arc B390 is not suitable for 4K gaming at high settings in this title. Even 4K Low (41 FPS) barely reaches playable territory.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B390 is an integrated graphics solution based on the Xe3-LPG architecture, built on Intel's 3 nm process. Its memory configuration is "System Shared," meaning it draws from system RAM rather than dedicated VRAM. The memory bus width and bandwidth are likewise listed as "System Shared" and "System Dependent," respectively, which means performance can vary based on the host system's memory configuration.

Clock speeds are modest, with a base of 300 MHz and a boost of 2500 MHz. The GPU has 1536 shading units, 48 texture mapping units, and 24 raster output pipelines. Its pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s provide the raw throughput that determines fill-rate limited scenarios. The FP32 performance of 7.680 TFLOPS positions this as a low-end graphics solution.

The GPU's benchmark results are limited to a single test: 3DMark Steel Nomad DX12, where it scores 1482. This places it in the 9th percentile of all GPUs. The nearest rivals — GT 520MX, GeForce 800M, GT 625 OEM, and GT 710 — are all legacy parts, which tells a clear story about where this GPU sits in the performance hierarchy.

In Pc Building Simulator, the GPU's limitations become evident at higher resolutions. The 4K results — 21 FPS at High, 29 FPS at Medium, 41 FPS at Low, and 20 FPS at Ultra — show that the rasterization throughput is simply insufficient for 4K gaming. Even at 1440p, only Low (79 FPS) and Medium (56 FPS) clear the 50 FPS mark. The 1080p results are more respectable, with all settings levels above 59 FPS, but the Ultra setting barely reaches that floor.

The system-shared memory architecture may also contribute to the scaling behavior. Since the GPU uses system memory rather than dedicated VRAM, bandwidth is shared with the CPU. The Ryzen 7 7700X supports DDR5 with 83.2 GB/s bandwidth, but this is split between CPU and GPU workloads. At higher resolutions, where the GPU needs more memory bandwidth for frame buffers and textures, this shared arrangement could exacerbate performance drops.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal settings depend heavily on the target resolution. At 1080p, the Medium preset at 88 FPS average (range 75–102) offers the best balance — it is 42% faster than High (62 FPS) and only 30% slower than Low (125 FPS), while providing better visual quality than Low. The min FPS of 75 ensures consistent frame delivery well above the typical 60 FPS target.

At 1440p, the Medium preset at 56 FPS average (range 47–64) is the highest quality setting that maintains an average above 50 FPS. The Low preset at 79 FPS provides more headroom for demanding scenes, making it the safer choice for players who prioritize smoothness. High (39 FPS) and Ultra (38 FPS) are best avoided due to sub-60 FPS averages.

At 4K, no setting achieves a 60 FPS average. The Low preset at 41 FPS is the only option that approaches playability, and even this may feel sluggish. Players targeting 4K should consider whether the game's simulation nature can tolerate lower frame rates, or whether dropping to 1440p is the better trade-off. Medium at 29 FPS and High/Ultra at 21/20 FPS are below acceptable thresholds for most players.

The data suggests that Medium settings provide the sweet spot for this combo at 1080p and 1440p. At 1080p, the 88 FPS average with a 75 FPS minimum ensures smooth gameplay even in complex simulation scenes. At 1440p, the 56 FPS average with a 47 FPS minimum is borderline but workable for a simulation game where twitch reactions are less critical. For players who prioritize absolute smoothness, dropping to Low at 1440p (79 FPS) or 1080p (125 FPS) provides substantial margin.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

1920x1080:

• Low: 125 FPS average
• Medium: 88 FPS average, 75 FPS minimum, 102 FPS maximum
• High: 62 FPS average
• Ultra: 59 FPS average

At 1080p, the full range of settings is playable. The gap between Low and Ultra is 66 FPS, with each step down in quality yielding meaningful gains. The Medium setting's min-max range of 75–102 FPS shows good frame consistency.

2560x1440:

• Low: 79 FPS average
• Medium: 56 FPS average, 47 FPS minimum, 64 FPS maximum
• High: 39 FPS average
• Ultra: 38 FPS average

At 1440p, the performance cliff becomes apparent. High and Ultra both sit below 40 FPS, while Low maintains a comfortable 79 FPS. The Medium setting's 47 FPS minimum is close to the edge of smoothness, but the 56 FPS average is acceptable for a simulation title.

3840x2160:

• Low: 41 FPS average
• Medium: 29 FPS average, 25 FPS minimum, 34 FPS maximum
• High: 21 FPS average
• Ultra: 20 FPS average

At 4K, the GPU is clearly overwhelmed. Even Low settings cannot reach 60 FPS, and the Medium setting's 25 FPS minimum drops below playable thresholds. The 21 FPS High and 20 FPS Ultra results are only suitable for static screenshots or non-interactive scenes.

The data shows a consistent pattern: each resolution step from 1080p to 1440p to 4K roughly halves the FPS at equivalent settings. This linear scaling behavior confirms that the Intel Arc B390's rendering throughput is the dominant constraint, with the AMD Ryzen 7 7700X providing ample CPU headroom throughout all tested configurations.
