Pc Building Simulator

Pc Building Simulator, a simulation title focused on the assembly and maintenance of virtual PCs, presents a unique workload that is less about traditional game engine rendering and more about CPU-bound logic, menu interactions, and 3D object manipulation. The benchmark data for the Intel Core i7-13700K paired with the NVIDIA GeForce RTX 4070 reveals a configuration that is heavily CPU-limited at lower resolutions, with the GPU only beginning to assert its influence as the pixel count climbs. This analysis decodes the measured FPS across three resolutions and four quality presets, interpreting the performance hierarchy and the specific roles of the processor and graphics card.

Resolution Scaling

The FPS deltas across resolutions tell a clear story about where the bottleneck lies in this pairing. At 1080p with Low settings, the combo produces 367 FPS, a figure so high that it strongly indicates the CPU is the limiting component, as the GPU is not being taxed by complex pixel work. Moving to 1440p Low drops the frame rate to 232 FPS, a 36.8% reduction, while at 4K Low it falls further to 121 FPS, which is a 47.8% drop from the 1440p figure. This scaling pattern is characteristic of a system where the graphics card is becoming the primary constraint as resolution increases, but the absolute numbers at Low settings show the CPU is still keeping pace with the GPU's output.

The scaling becomes more nuanced when examining the Medium preset, which is the only preset with min and max FPS data. At 1080p Medium, the average is 260 FPS with a min of 221 and max of 299. At 1440p Medium, the average drops to 164 FPS (a 36.9% reduction), with a min of 140 and max of 189. At 4K Medium, the average is 86 FPS, a 47.6% reduction from 1440p, with a min of 73 and max of 99. The percentage drops from 1080p to 1440p and from 1440p to 4K are nearly identical for Low and Medium presets, which suggests a consistent scaling factor related to the GPU's rendering workload, rather than an abrupt shift in the bottleneck.

For the High preset, the scaling is similar: 184 FPS at 1080p, 116 FPS at 1440p (a 37.0% drop), and 61 FPS at 4K (a 47.4% drop from 1440p). The Ultra preset shows the same pattern, with 175 FPS at 1080p, 110 FPS at 1440p (a 37.1% drop), and 58 FPS at 4K (a 47.3% drop from 1440p). The consistency of these percentage drops—roughly 37% from 1080p to 1440p and 47% from 1440p to 4K—across all presets is a strong indicator that the scaling is purely a function of GPU pixel throughput. The CPU is not a factor in these deltas, as its workload does not change significantly with resolution.

The data implies that at 1080p, the system is so far ahead of the display's refresh rate capabilities that the CPU's frame generation limit is the only thing preventing even higher numbers. At 4K, the RTX 4070’s rendering capabilities are the definitive ceiling, with the CPU having ample headroom. The fact that the 1080p Ultra (175 FPS) is nearly triple the 4K Ultra (58 FPS) highlights the massive performance cost associated with the 4K pixel count on this GPU. The GPU's memory bandwidth of 504.2 GB/s and 12 GB of GDDR6X are likely sufficient for the game's assets, making the raw shader throughput the primary scaling factor.

How This Combo Ranks

The combo's rank in Pc Building Simulator is 806 out of 3723 tested combinations, placing it in the top 21.6% of all configurations. This is a respectable position, but it is not a top-tier ranking, which is surprising given the high-end nature of the components. The rank suggests that while this setup is very capable, there are many other combinations that achieve higher average frame rates in this specific simulation game. This is likely because the game's CPU-bound nature at lower resolutions means that processors with even higher single-thread performance, or combinations with different balance, can pull ahead.

The CPU's percentile rank of 89 (vs. all CPUs) and the GPU's percentile rank of 81 (vs. all GPUs) are informative. The CPU is clearly a stronger performer relative to its peers than the GPU. This disparity supports the notion that in many scenarios, particularly at 1080p, the CPU is the star of the show. The GPU is a solid performer, but it is not as exceptional within its own market segment as the i7-13700K is. This hierarchy is reflected in the game's performance, where the combo's rank is likely held back by the GPU's performance at higher resolutions.

When we look at the nearest rivals for the CPU, the Intel Core i7-13700K has an average benchmark score of 46881. Its closest competitor, the AMD Ryzen 9 5900, scores 46971, which is a mere 0.2% higher. The AMD Ryzen AI 9 HX PRO 375 is 0.3% higher, while the AMD Ryzen 9 7845HX and Intel Xeon w3-2535 are both 0.5% lower. This indicates that the CPU's performance is right in the middle of a very tight cluster of high-end processors. The GPU's nearest rivals show a similar clustering, with the RTX 4070's average score of 37648 being only 0.1% higher than the NVIDIA Tesla P4 and 0.4% higher than the AMD Radeon RX Vega 56. The NVIDIA GeForce RTX 4080 Mobile is 1.3% higher, and the AMD Radeon PRO W6400 is 1.3% lower. This data suggests that the combo's rank is not due to any single component being a weak link, but rather the combination of two good, but not best-in-class, parts.

CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread processor based on the Raptor Lake architecture. Its configuration of 8 performance cores and 8 efficiency cores allows it to handle both heavily threaded workloads and single-threaded tasks with ease. The base clock of 3.40 GHz and a boost clock of 5.40 GHz mean that in lightly threaded scenarios, such as the menus and UI interactions that are prevalent in Pc Building Simulator, it can reach very high frequencies. The L3 cache is 30 MB shared, which helps to keep frequently accessed data close to the cores.

In the context of this game, the CPU's role is critical. The benchmark results show that at 1080p Low, the system achieves 367 FPS. This is a very high frame rate that is likely limited by the CPU's maximum frame generation capacity. The CPU's benchmark scores corroborate its strength; for instance, its Cinebench R23 multi-core score is 30745 and its single-core score is 2116. The 3DMark 16-thread score of 10717 and 2-thread score of 2262 show that the CPU scales well with thread count, but also has substantial single-thread power. This is ideal for a simulation game that may have significant logic running on a main thread.

The data demonstrates that the CPU is not a bottleneck at 4K, where the GPU is clearly the limiting factor. However, at 1080p, the CPU is likely the reason the FPS does not go even higher than 367. The CPU's high performance is evident, and it provides a massive amount of headroom for the GPU at all resolutions. The PassMark multithread score of 45887 and single-thread score of 4333 are indicative of a processor that can easily feed a high-end graphics card. The CPU's 125 W TDP and support for DDR4 and DDR5 memory provide a flexible platform, but the benchmark data suggests that its raw compute power is more than sufficient for this title.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at the system's performance across all settings. At 1920x1080, the Low preset yields an average of 367 FPS, which is the highest recorded. The Medium preset averages 260 FPS, with a minimum of 221 FPS and a maximum of 299 FPS. The High preset averages 184 FPS, and the Ultra preset averages 175 FPS. The scaling from Low to Ultra at 1080p shows a 52.3% reduction in FPS, indicating that the visual fidelity settings have a significant impact on the GPU's workload, but the absolute numbers are always high.

Moving to 2560x1440, the Low preset averages 232 FPS. The Medium preset averages 164 FPS, with a minimum of 140 FPS and a maximum of 189 FPS. The High preset averages 116 FPS, and the Ultra preset averages 110 FPS. At this resolution, the system is still delivering very playable frame rates across all presets. The gap between High and Ultra is just 6 FPS, suggesting that the Ultra preset's additional effects are not extremely demanding on this GPU, or that the CPU is starting to become a limiting factor in these higher settings.

At 3840x2160, the performance becomes more demanding. The Low preset averages 121 FPS, which is still smooth for most displays. The Medium preset averages 86 FPS, with a minimum of 73 FPS and a maximum of 99 FPS. The High preset averages 61 FPS, and the Ultra preset averages 58 FPS. At 4K, the Ultra preset is just below the 60 FPS threshold for smooth gameplay, while the High preset barely reaches it. The data shows a clear progression: the system is overkill for 1080p, strong for 1440p, and just adequate for 4K on the highest settings. The min FPS data for Medium at all resolutions (221, 140, 73) shows that frame pacing is consistent, with no major stutters or drops.

GPU Role

The NVIDIA GeForce RTX 4070 is a 5 nm chip with 5888 shading units and 46 RT cores. Its boost clock is 2475 MHz, and it has 12 GB of GDDR6X memory on a 192-bit bus, providing a bandwidth of 504.2 GB/s. The GPU's FP32 performance is 29.15 TFLOPS, which is a measure of its raw compute capability. In the context of Pc Building Simulator, the GPU's role is to render the 3D models of the computer components and the workshop environment. The game is not graphically intense, but the benchmark data shows that the GPU is the limiting factor at 4K.

The GPU's average benchmark score is 37648, and its percentile rank is 81. Its nearest rival, the NVIDIA Tesla P4, has a score of 37628, which is a 0.1% difference. This shows the GPU is performing as expected. The data from the game suggests that the RTX 4070 is more than capable of handling the game at 1080p and 1440p, but at 4K, its performance drops considerably. The 4K Ultra preset yields 58 FPS, which is below the 60 FPS target. This is not a failure of the GPU, but rather a reflection of the high pixel count and the game's rendering demands at that resolution.

The GPU's memory configuration is likely sufficient. The 12 GB of VRAM is more than enough for a game of this visual complexity, and the 504.2 GB/s bandwidth ensures that textures and geometry can be streamed quickly. The GPU's 158.4 GPixel/s pixel rate is a key factor in the resolution scaling. The data shows that the GPU is the dominant component in determining FPS at 4K, as the CPU has ample headroom. When comparing the 1080p Low (367 FPS) to the 4K Low (121 FPS), the 3x reduction in FPS is directly attributable to the GPU's pixel processing capabilities. The GPU is also the reason that the Ultra preset at 1440p (110 FPS) is nearly identical to the 4K High preset (61 FPS), as the increased resolution of 4K negates the visual improvements of the Ultra preset.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and desired frame rate. For 1920x1080, all presets are playable, but the Ultra preset at 175 FPS is the best choice for maximum visual quality, as it still provides a frame rate far above any display's refresh rate. There is no reason to use lower settings at 1080p, as the performance headroom is massive. The data shows that even the most demanding preset is not a challenge for the system.

For 2560x1440, the Ultra preset at 110 FPS is also the recommended choice. It provides a smooth experience on high refresh rate monitors and offers the best visual fidelity. The High preset at 116 FPS is nearly identical in performance, so the Ultra preset is the better value for the minimal FPS cost. The Medium preset at 164 FPS could be used for esports-style play, but it is unnecessary given the high frame rates of the higher presets.

For 3840x2160, the recommendation is more nuanced. The High preset at 61 FPS is the best choice for a 60 Hz display, as it provides a stable frame rate with good visual quality. The Ultra preset at 58 FPS is very close, but it dips below 60 FPS, which can be noticeable. The Medium preset at 86 FPS is a strong option for those with 4K displays that support higher refresh rates, and it offers a significant FPS boost over High and Ultra. The data suggests that for a fluid 4K experience, the Medium preset is the sweet spot, balancing visual fidelity with a comfortable margin above 60 FPS. The Low preset at 121 FPS is for those who prioritize raw FPS over all else, but the visual quality reduction is likely too severe for a title that is about inspecting components.
