Pc Building Simulator

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

The AMD Ryzen 7 3700X brings an 8-core, 16-thread configuration built on the Zen 2 (Matisse) architecture, fabricated on TSMC's 7 nm process. With a base clock of 3.60 GHz and a boost clock of 4.40 GHz, this CPU operates with a 65 W TDP on the AMD Socket AM4 platform. The processor's cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a 32 MB L3 pool, which is substantial for a simulation title that tends to manage many concurrent objects.

In Pc Building Simulator, the workload is largely physics- and logic-driven, but the data shows that the CPU rarely becomes the primary constraint at the tested settings. The CPU's Cinebench R23 multicore score of 19087 and single-core score of 2694 indicate strong multi-threaded throughput, yet the game's frame rates scale more with GPU settings than with CPU capability. The Passmark multithread score of 22458 and single-thread score of 2656 reinforce this picture: the 3700X delivers balanced performance that is adequate for feeding the GPU at lower resolutions.

The nearest rivals in the CPU benchmark database are the Intel Core i5-12600 with an average score of 28654 (deltaPct -0.1), the Intel Core i5-12600H at 28666 (deltaPct -0.1), the AMD Ryzen 5 5600XT at 28591 (deltaPct 0.1), and the AMD EPYC 7203P at 28583 (deltaPct 0.2). The 3700X's average benchmark score of 28631 places it essentially on par with these processors, with deltas well within 1%. This means that in raw compute terms, the CPU is not a differentiator; its 85th percentile ranking among all CPUs confirms it sits comfortably in the upper tier without being exceptional.

For Pc Building Simulator specifically, the CPU's role is to maintain consistent frame pacing. At 1080p Low, the measured average FPS of 267.6 suggests the CPU can sustain high throughput, but the gap between Low and Ultra at 1080p (267.6 vs 192.8) is only about 28%, which is modest compared to the GPU-driven scaling seen at higher resolutions. The 3700X's 16 threads are more than sufficient for this title, and the data indicates that even at 4K Ultra, the CPU is not the limiting factor — the FPS drop from 1080p Ultra to 4K Ultra is steep (192.8 to 63.1), which points squarely at GPU load.

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

The NVIDIA GeForce RTX 4070 SUPER is built on the Ada Lovelace architecture with the AD104 chip, using TSMC's 5 nm process. It packs 7168 shading units, 224 texture mapping units, and 80 ROPs, along with 56 RT cores and 224 tensor cores. The memory subsystem consists of 12 GB of GDDR6X on a 192-bit bus, delivering 504.2 GB/s of bandwidth. Clocks are set at a base of 1980 MHz and a boost of 2475 MHz, with memory running at 1313 MHz (21 Gbps effective).

In Pc Building Simulator, the GPU is clearly the dominant performance driver. The 3DMark Steel Nomad DX12 score of 4627 and Passmark G3D score of 29995 place the 4070 SUPER in a strong position, with an 84th percentile ranking among all GPUs. Its average benchmark score of 42576 is nearly identical to the NVIDIA RTX A6000 (42653, deltaPct -0.2) and the AMD Radeon RX 7650 GRE (42723, deltaPct -0.3), while sitting just ahead of the AMD Radeon Pro 580X (41991, deltaPct 1.4) and the NVIDIA Tesla M40 (41897, deltaPct 1.6).

The GPU's VRAM capacity of 12 GB is more than adequate for this simulation title, which does not appear to push memory limits even at 4K Ultra. The measured FPS at 4K Ultra is 63.1, which is playable but not high-refresh territory. The RTX 4070 SUPER's FP32 throughput of 35.48 TFLOPS provides ample compute for the game's rendering tasks, and the 220 W TDP with a 550 W suggested PSU indicates a power envelope that is reasonable for this performance class.

The data reveals that the GPU's role scales dramatically with settings. At 1080p Low, the card produces 267.6 FPS, but at 4K Ultra it drops to 63.1 FPS — a reduction of over 76%. This is classic GPU-bound behavior, where pixel throughput and shading complexity become the limiting factors. The RTX 4070 SUPER's 198.0 GPixel/s pixel rate and 554.4 GTexel/s texture rate are the key specifications driving these results, and the game's modest visual demands mean the card rarely struggles at lower resolutions.

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

The measured FPS data shows a clear and consistent pattern of GPU-bound scaling across resolutions. Starting at 1920x1080, the average FPS ranges from 192.8 (Ultra) to 267.6 (Low). Moving to 2560x1440, the averages drop to 123.1 (Ultra) and 228.9 (Low). At 3840x2160, the figures fall further to 63.1 (Ultra) and 134.1 (Low).

The percentage drops from 1080p to 4K are revealing. For Ultra settings, the drop is from 192.8 to 63.1 FPS, which is a reduction of approximately 67%. For High settings, the drop is from 204 to 64.9 FPS, about 68%. Medium settings fall from 234 to 92.9 FPS, roughly 60%. Low settings drop from 267.6 to 134.1 FPS, which is about 50%. These scaling factors are consistent with a GPU that is increasingly stressed as resolution increases, while the CPU maintains sufficient headroom.

The fact that the Low setting at 4K (134.1 FPS) is still higher than the Ultra setting at 1440p (123.1 FPS) highlights how much of the performance difference is tied to shading and pixel work rather than resolution alone. At 1080p, the GPU is so far ahead of the game's demands that frame rates exceed 190 FPS even at Ultra, indicating that the CPU and game engine are capable of feeding frames at a very high rate. The limiting component is unambiguously the GPU when moving to higher resolutions, as the CPU's role remains constant while FPS scales inversely with pixel count.

The 4K Ultra result of 63.1 FPS is particularly telling. It suggests that even a high-end GPU like the RTX 4070 SUPER cannot fully overcome the pixel throughput demands at 4K with maximum settings in this title, but it remains comfortably within playable territory. The 1440p Ultra result of 123.1 FPS offers a strong balance, and the 1080p results show that the CPU is never a bottleneck at any setting.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 7 3700X and NVIDIA GeForce RTX 4070 SUPER achieves a rank of 464 out of 1769 tested combos in Pc Building Simulator. This places the combo in the top 26% of all configurations tested, which is a solid result given the CPU's 85th percentile and the GPU's 84th percentile standings individually.

The rank of 464 is somewhat lower than what the individual component percentiles might suggest, which indicates that the game's performance is not purely additive. The CPU's performance tier is sufficient, but the GPU's capabilities are what drive the final ranking. Since the data shows the GPU is the primary limiter at higher resolutions, the combo's rank is likely held back by the CPU in scenarios where frame rates are very high (e.g., 1080p Low at 267.6 FPS), but the GPU is the decisive factor at 4K.

Compared to other combos in the database, this pairing sits in the upper-middle tier. The fact that it ranks 464th out of 1769 means there are 463 combos that perform better, which likely include newer CPUs or higher-tier GPUs. However, the delta between this combo and those above it is not specified, so the exact performance gap cannot be quantified. What is clear is that the combo delivers consistent frame rates across all tested resolutions and settings, with no anomalous dips that would indicate a bottleneck or compatibility issue.

The rank also reflects the game's specific demands. Pc Building Simulator is not a graphically intensive title by modern standards, so the RTX 4070 SUPER is over-provisioned for much of the tested range. This means the CPU's contribution to the final rank is more pronounced at lower resolutions where the GPU has headroom, but the overall ranking is still dominated by GPU throughput.

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

1920x1080 (1080p)

• Low: 267.6 FPS average
• Medium: 234.0 FPS average
• High: 204.0 FPS average
• Ultra: 192.8 FPS average

At 1080p, the RTX 4070 SUPER is never challenged. Even at Ultra, the frame rate exceeds 190 FPS, and the spread from Low to Ultra is only 74.8 FPS, which is a 28% reduction. This indicates that the game's settings at 1080p have a limited impact on GPU load, and the CPU can sustain very high frame delivery.

2560x1440 (1440p)

• Low: 228.9 FPS average
• Medium: 180.6 FPS average
• High: 128.7 FPS average
• Ultra: 123.1 FPS average

At 1440p, the scaling becomes more pronounced. The gap between Low and Ultra widens to 105.8 FPS, a 46% reduction. The High and Ultra settings are close together (128.7 vs 123.1), suggesting that the additional settings beyond High have diminishing returns on visual quality but still cost some performance. The Low setting remains above 200 FPS, which is excellent for competitive play.

3840x2160 (4K)

• Low: 134.1 FPS average
• Medium: 92.9 FPS average
• High: 64.9 FPS average
• Ultra: 63.1 FPS average

At 4K, the GPU is clearly the limiting factor. The drop from Low to Medium is 41.2 FPS, and from Medium to High is 28.0 FPS. The High and Ultra settings are nearly identical (64.9 vs 63.1), which suggests that the Ultra preset adds effects that have minimal additional GPU cost beyond High in this title. The Low setting at 134.1 FPS is still very playable, but the Ultra setting at 63.1 FPS is at the edge of high-refresh gaming.

The overall pattern across all resolutions shows a consistent hierarchy: Low is always fastest, followed by Medium, then High, with Ultra being the slowest. The relative gaps between settings grow with resolution, confirming that the GPU is the primary performance determinant. The data indicates that for a smooth 60+ FPS experience at 4K, the High preset (64.9 FPS) is the maximum viable setting, while at 1440p, Ultra (123.1 FPS) is comfortable, and at 1080p, all settings deliver well over 190 FPS.
