# Pc Building Simulator — Intel Core i5-12600KF + NVIDIA GeForce RTX 5090 D

This combination of Intel's 10-core Alder Lake processor and NVIDIA's flagship Blackwell GPU produces exceptional frame rates in Pc Building Simulator, a simulation title that proves far less demanding than modern AAA shooters. The measured data shows the RTX 5090 D delivering triple-digit average FPS at every resolution tested, with the combo ranking in the 98.7th percentile of all 3,002 tested configurations. The performance profile reveals a system that is overwhelmingly GPU-bound at higher resolutions but begins to show CPU limitations at 1080p, particularly at lower settings where frame rates exceed 390 FPS.

Resolution Scaling

The resolution scaling pattern in Pc Building Simulator is remarkably linear for this hardware combo, though the rate of FPS decline from 1080p to 4K varies significantly by quality preset. At High settings, the average FPS drops from 284 at 1920x1080 to 179 at 2560x1440 — a 37% reduction — and then to 94 at 3840x2160, representing a 47% further drop from 1440p. This steepening decline suggests the GPU is becoming progressively more loaded as pixel count increases, which is expected given the RTX 5090 D's 32 GB of GDDR7 memory and 512-bit bus width.

The Low preset reveals a more intriguing pattern. At 1080p Low, the combo achieves 394 FPS average, which falls to 338 at 1440p (a 14% decline) and then to 187 at 4K (a 45% decline from 1440p). The relatively modest drop from 1080p to 1440p at Low settings compared to the larger 4K decline indicates that at 1080p Low, the system is likely hitting a CPU-side ceiling rather than a GPU limitation. The i5-12600KF's 10 cores and 16 threads, running at a 4.90 GHz boost clock, appear sufficient to feed the GPU at lower resolutions, but the 4K pixel workload finally shifts the bottleneck firmly to the graphics card.

Medium settings show intermediate behavior: 347 FPS at 1080p, 254 FPS at 1440p (27% lower), and 133 FPS at 4K (48% lower than 1440p). The Ultra preset delivers 270 FPS at 1080p, 171 FPS at 1440p (37% lower), and 89 FPS at 4K (48% lower). Across all presets, the 4K-to-1440p ratio hovers around 0.47-0.53, while the 1440p-to-1080p ratio varies more widely (0.63-0.86), reinforcing that the GPU becomes the dominant limiting factor as resolution climbs. The data indicates that at 1080p, particularly on Low settings, the CPU's single-thread performance (3,302 in Cinebench R23 single-core) and multi-thread capabilities (23,391 in Cinebench R23 multi-core) are the constraining variables, while at 4K the RTX 5090 D's raw compute throughput governs the outcome.

How This Combo Ranks

This specific pairing of the Intel Core i5-12600KF with the NVIDIA GeForce RTX 5090 D achieves a combo rank of 39 out of 3,002 tested configurations in Pc Building Simulator, placing it in the top 1.3% of all systems evaluated. This top-40 placement is notable because the CPU itself only ranks in the 79th percentile of all processors in general benchmark comparisons, with an average benchmark score of 27,799. The GPU, by contrast, sits in the 92nd percentile of all graphics cards with an average score of 77,712.

The rank discrepancy between the components' individual standings and their combined performance in this title suggests that Pc Building Simulator's workload does not heavily stress the CPU, allowing the RTX 5090 D's immense graphics horsepower to shine. The i5-12600KF's nearest rivals in general CPU benchmarks include the Intel Core i9-10900K and AMD Ryzen 7 5800X3D, both scoring within 0.3% of the i5-12600KF's average — a statistical tie. The GPU's nearest rivals include the AMD Radeon RX 6850M XT at 1.6% higher average score and the NVIDIA Tesla P100 PCIe 16 GB at 2.4% higher, though these are not direct market competitors.

Within the context of the 3,002 combos tested, this system's rank of 39 places it alongside configurations that likely feature higher-tier CPUs paired with the same flagship GPU. The data implies that in Pc Building Simulator, the marginal benefit of a more expensive processor over the i5-12600KF is minimal, as the combination already delivers frame rates far beyond what most displays can show at 4K Ultra (89 FPS average) and well above 240 Hz thresholds at 1080p on any preset.

GPU Role

The NVIDIA GeForce RTX 5090 D is the dominant contributor to this combo's performance in Pc Building Simulator. Built on the Blackwell 2.0 architecture with a GB202 chip fabricated on TSMC's 5 nm process, this GPU packs 21,760 shading units, 680 texture mapping units, and 176 ROPs. Its boost clock of 2,407 MHz and base clock of 2,017 MHz provide the computational foundation for the measured frame rates, while the memory subsystem — 32 GB of GDDR7 on a 512-bit bus delivering 1.79 TB/s bandwidth — ensures that even 4K resolutions with high-quality textures face no capacity constraints.

The GPU's benchmark scores reflect its top-tier positioning. In 3DMark Steel Nomad DX12, it scores 14,326, while Geekbench OpenCL and Vulkan scores reach 310,674 and 376,915 respectively. The PassMark G3D score of 44,065 and GPU compute score of 28,396 further quantify its capabilities. In this simulation title, the GPU's role is most evident in the resolution scaling data: at 4K Ultra, the average FPS of 89 represents a 67% reduction from the 270 FPS at 1080p Ultra, a drop that directly correlates with the fourfold increase in pixel count.

The RTX 5090 D's nearest rivals in general benchmarks — the AMD Radeon RX 6650M XT at 1.1% higher average score and the Radeon RX 6850M XT at 1.6% lower — are mobile-class parts that would not be expected to compete with this desktop flagship in real gaming workloads. This discrepancy highlights that the GPU's percentile ranking (92nd) is measured against all GPUs including professional and mobile variants, but its actual gaming performance in this title is demonstrated by the consistently high FPS figures. The 575 W TDP and 950 W suggested PSU rating indicate the power delivery required to sustain these clocks, though the measured FPS data shows no signs of thermal throttling or performance instability.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target display's refresh rate and resolution. At 3840x2160, the High preset delivers 94 FPS average, which is suitable for 60 Hz displays but falls short of 120 Hz targets. The Medium preset at 4K produces 133 FPS average with a minimum of 113 FPS and maximum of 153 FPS, making it the best choice for high-refresh 4K monitors — the min FPS stays comfortably above 100, ensuring smooth frame pacing. The Ultra preset at 4K drops to 89 FPS average, which is still playable but represents a 33% performance penalty over High with presumably marginal visual gains in a simulation game.

The data shows that the Low preset at 4K yields 187 FPS, which is more than double the Ultra frame rate, but the visual quality sacrifice in a game centered on PC building and component observation may not be worthwhile. For 2560x1440, the Ultra preset at 171 FPS average exceeds the refresh rate of most 144 Hz monitors, making it the recommended choice for 1440p users who want maximum visual fidelity without compromising smoothness. The Medium preset at 1440p reaches 254 FPS average with a minimum of 216 FPS, suitable for 240 Hz displays, while High at 179 FPS sits in between.

At 1920x1080, all presets deliver frame rates above 270 FPS, with Low reaching 394 FPS and Medium at 347 FPS. For 1080p gaming, the Ultra preset's 270 FPS average is more than sufficient for even the fastest 240 Hz or 360 Hz esports displays. Given that Pc Building Simulator is a simulation title where visual detail of components matters for the experience, the Medium or High presets at 1080p provide the best balance, with the Medium preset's minimum FPS of 295 ensuring no noticeable hitches. The measured data suggests that Medium settings offer the most consistent frame time performance across all resolutions, as it is the only preset with recorded min and max FPS values showing tight variance.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values are: Low at 394 FPS, Medium at 347 FPS (min 295, max 399), High at 284 FPS, and Ultra at 270 FPS. The spread from Low to Ultra is 124 FPS, representing a 31% performance difference between the lowest and highest quality presets. The Medium preset's minimum of 295 FPS is notably higher than the High and Ultra averages, indicating that even the most demanding scenes in the benchmark stay well above 300 FPS at this resolution when using Medium settings.

Moving to 2560x1440, the average FPS values are: Low at 338 FPS, Medium at 254 FPS (min 216, max 292), High at 179 FPS, and Ultra at 171 FPS. The drop from Low to Medium is 84 FPS (25%), from Medium to High is 75 FPS (30%), and from High to Ultra is a modest 8 FPS (4.5%). This small difference between High and Ultra at 1440p suggests diminishing returns from the Ultra preset's additional graphical features, making High the more efficient choice for 1440p users.

At 3840x2160, the average FPS values are: Low at 187 FPS, Medium at 133 FPS (min 113, max 153), High at 94 FPS, and Ultra at 89 FPS. The resolution increase from 1440p to 4K reduces performance by approximately 45-48% across Medium, High, and Ultra presets, while the Low preset drops by 45% as well. The Ultra preset at 4K (89 FPS) is only 5 FPS lower than High (94 FPS), again indicating that the visual uplift from High to Ultra comes at a minimal performance cost but also suggesting that both presets are GPU-limited in similar ways. The Medium preset at 4K, with its 113 FPS minimum, is the only 4K option that guarantees frame rates above 100 FPS at all times.

CPU Role

The Intel Core i5-12600KF plays a supporting but non-trivial role in this combo's Pc Building Simulator performance. This 10-core, 16-thread processor from the Alder Lake-S architecture operates with a 3.70 GHz base clock and 4.90 GHz boost clock, built on Intel's 10 nm process with a 125 W TDP. Its cache hierarchy includes 80 KB L1 per core, 1.25 MB L2 per core, and 20 MB shared L3 cache, providing the memory subsystem with ample fast storage for game data.

The CPU's benchmark results demonstrate strong multi-threaded performance: Cinebench R23 multi-core scores 23,391, while single-core reaches 3,302. The 3DMark tests show scaling from 1,016 in single-thread to 7,956 in 16-thread workloads, indicating good parallel efficiency. Geekbench scores of 12,137 multi-core and 2,157 single-core, along with PassMark multi-thread at 27,575 and single-thread at 3,925, place this CPU in the 79th percentile of all processors.

In Pc Building Simulator, the CPU's influence is most apparent at 1080p resolution with lower settings. The Low preset at 1080p achieves 394 FPS, which is only 14% higher than the 338 FPS at 1440p Low — a smaller improvement than the 33% pixel reduction would suggest if the GPU were the sole bottleneck. This indicates that at 1080p Low, the i5-12600KF's per-core performance becomes the limiting factor. The CPU's nearest rivals in general benchmarks — the Intel Core i9-10900K and AMD Ryzen 7 5800X3D — score within 0.3% of the i5-12600KF's average, confirming that this mid-range 12th Gen part holds its own against higher-tier options.

However, the CPU's 10 cores and 16 threads are more than adequate for this simulation title's workload. The fact that the combo ranks 39th overall, despite the CPU being in the 79th percentile, suggests that Pc Building Simulator does not heavily tax multi-threaded CPU performance. The game's simulation aspects — tracking component specifications, power draw, and thermal loads — likely utilize only a few threads, making the i5-12600KF's strong single-core performance (3,302 in Cinebench R23 single-core) more relevant than its multi-core capabilities. This is further evidenced by the minimal FPS difference between High and Ultra presets at each resolution, indicating that CPU-side physics or logic calculations are not the primary bottleneck in this title.
