Pc Building Simulator

The AMD Ryzen 7 7700 and NVIDIA GeForce RTX 5070 pairing is a mid-range desktop combination that handles Pc Building Simulator with ease, but the simulation's light rendering demands expose a mix of CPU and GPU headroom. With the CPU finishing in the 87th percentile against all tested processors and the GPU in the 82nd, this combo sits near the top of the database's tested configurations, placing 678th out of 3,723 individual combos. Across four resolutions and four quality presets, the measured data shows that the pairing delivers frame rates ranging from 62 FPS (4K Ultra) to 392 FPS (1080p Low), making it flexible for both high-refresh monitors and high-fidelity 4K displays. The next sections break down how resolution, graphics memory, and the processor's multicore strength shape these results.

Resolution Scaling

Pc Building Simulator's performance scales predictably with total pixel count, but the magnitude of the drop from 1080p to 4K differs by preset. At Low settings, 1080p yields 392 FPS, 1440p yields 248 FPS, and 4K drops to 129 FPS — a 3.04× reduction from 1080p to 4K, almost exactly the pixel ratio (4K has 4× the pixels of 1080p, but the game's large UI and viewport scaling appear to mitigate some of the load). The Ultra preset shows a similar pattern: 1080p runs at 187 FPS, 1440p at 118 FPS, and 4K falls to 62 FPS — again a 3.0× ratio. Medium settings give the cleaner numbers: 1080p at 278 FPS, 1440p at 175 FPS, and 4K at 92 FPS, with all three above the stable 60 FPS threshold.

The drop from 1080p to 4K at each preset reveals that the limiting component is the graphics card, not the CPU. At 1080p, the CPU can feed the GPU enough frames to hit 392 FPS at Low, but when resolution jumps, the GPU's pixel and texture throughput become the ceiling. With High settings, 1080p gives 196 FPS, 1440p 124 FPS, and 4K 65 FPS. Ultra's 187 FPS at 1080p scales to 118 at 1440p and 62 at 4K — a larger relative drop (from 187 to 62 is 3.0×) than from 1080p to 4K at Low, confirming that higher-quality settings amplify the GPU's role.

Crucially, the frame rates don't crumble under 4K; even at Ultra the game stays above 60 FPS. This indicates no serious CPU bottleneck at 4K — the Ryzen 7 7700's eight cores handle the simulation's heavy integer and logic computations without stalling the frame pipeline. The results align with a game that is primarily graphics-bound at high resolutions but shows dramatic headroom when the resolution is lowered.

GPU Role

The RTX 5070's role in these numbers is defined by its 12 GB density and 192-bit memory bus, delivering a bandwidth of 672.0 GB/s. With a base clock of 2325 MHz and boost up to 2512 MHz, the GPU sustains high fill rates. In the synthetic benchmarks, the card scores 29,137 on Passmark G3D, 172,660 on GeekBench OpenCL, and 178,923 on Vulkan, indicating strong compute throughput. Yet Pc Building Simulator's geometry is light; the 12 GB frame buffer at 4K with Ultra settings consumes enough to force the GPU's shader units to work harder. At 4K Ultra, average FPS is 62, and at 4K Medium it's 92 — both well within playable range.

The GPU's raw pixel rate (201.0 GPixel/s) and texture rate (482.3 GTexel/s) keep the game fluid, but the settings-dependent scaling shows that memory bandwidth becomes a secondary factor. At 1080p Low, the GPU is so far ahead that the CPU likely threads the frame construction; at 4K Ultra, the GPU's shading and memory write are saturated, as evidenced by the near-3× FPS loss from 1080p. The card also includes 6,144 shading units and 48 RT cores, but Pc Building Simulator is predominantly for system-building and not real-time ray tracing — the only fixed lighting and simple materials don't exercise the RT cores. The GPU's nearest rival in composite benchmarks is the AMD Radeon Pro 580, which scores a delta of +0.1%, indicating the card is on a performance parity at the synthetic level, but the game-specific measured frames put it ahead of typical workstation GPUs in real-time workloads.

How This Combo Ranks

The combination of the AMD Ryzen 7 7700 and NVIDIA GeForce RTX 5070 appears as the 678th best pairing out of 3,723 tested combos in Pc Building Simulator, putting it in the top 18.2% of all configurations. That's a strong showing for a 65 W CPU and a 250 W GPU (the CPU's rated TDP is 65 W, the GPU's 250 W). The rank reflects that the game's moderate graphics load allows small-and-budget-oriented hardware to perform exceptionally well, but this combo still exceeds many midrange options. For context, the CPU sits at the 87th percentile among all CPUs, while the GPU is at the 82nd, so neither component is a weak link — both are above average. The nearest CPU rivals in average benchmark score are the AMD Ryzen AI 9 365 (delta +0.1%), the Intel Core 5 221E (delta -0.2%), and the Intel Core i9-13905H (delta -0.6%), confirming the 7700 is at the top of its pricing tier in multi-core performance. The GPU’s nearest rivals are the AMD Radeon Pro 580 (delta +0.1%) and the AMD Radeon Pro WX 7100 (delta +0.8%), all of which are slower, though the RTX 5070's game numbers break away for this title.

Settings Recommendations

With the measured data, the best experience for a typical mid-range monitor is the Medium preset. At 1440p Medium, the average 175 FPS maxes out most 144 Hz displays and keeps the 1% lows at 149 FPS — still above 60. If you have a 4K display, Medium at 4K gives 92 FPS (with a minimum of 78 FPS and a maximum of 105 FPS) — a solid high-FPS experience without needing to sacrifice visual detail. High settings also work well at 1440p (124 FPS) and 1080p (124 FPS), but the frame gain from Medium to High is only 2–5 FPS at 1440p, and the 4K High value of 65 FPS is just above the 60 FPS threshold, so High is acceptable if you prioritize image quality. Ultra is the most demanding preset: it achieves 187 FPS at 1080p, 118 FPS at 1440p, and only 62 FPS at 4K. If you have a 4K 60Hz monitor, Ultra is just playable — but for 144Hz monitors, Medium at 1440p is the sweet spot.

The measured data suggests that Medium yields the best balance of visual fidelity and frame consistency. The only frame time measurements in the dataset are those for Medium, and they confirm stability: at 1080p Medium, the 236 FPS minimum and 320 FPS maximum with an average of 278 FPS; at 1440p Medium, the range is 149–202 with a 175 average; at 4K Medium, the range is 78–105 with a 92 average. None of these lows dip into stutter territory. Going above Medium to High or Ultra usually brings a 10–30% FPS drop, while going to Low kills visual quality for little extra speed — Low at 1080p jumps to 392 FPS but the game's textures and lighting are clearly not intended for that preset.

Measured FPS Breakdown

The following table gives the full set of measured averages (and min/max where available):

| Resolution | Preset | Avg FPS | Min FPS | Max FPS |

|------------|----------|---------|---------|---------|

| 1920×1080 | Low | 392 | – | – |

| 1920×1080 | Medium | 238 | – | – |

| 1920×1080 | High | 196 | – | – |

| 1920×1080 | Ultra | 187 | – | – |

| 2560×1440 | Low | 248 | – | – |

| 2560×1440 | Medium | 175 | 149 | 202 |

| 2560×1440 | High | 124 | – | – |

| 2560×1440 | Ultra | 118 | – | – |

| 3840×2160 | Low | 129 | – | – |

| 3840×2160 | Medium | 92 | 78 | 105 |

| 3840×2160 | High | 65 | – | – |

| 3840×2160 | Ultra | 62 | – | – |

The numbers show a clear trend: at 1080p, all presets deliver more than 187 FPS, with Low reaching 12% vs 10% between ultra and low. At 1440p, the cut from Medium to High costs 51 FPS (175 to 124), and High to Ultra only 6 FPS (124 to 118), indicating that the preset's difference is in geometric detail rather than shader load. At 4K, the progression from Low to Medium to High to Ultra goes 129 → 92 → 65 → 62, showing diminishing returns after Medium. The lack of min/max data for all presets except Medium limits deeper analysis, but the average spreads align with the GPU's pixel throughput.

CPU Role

The Ryzen 7 7700 brings eight physical cores with sixteen threads, a base clock of 3.80 GHz, and a boost up to 5.30 GHz. Its 65 W TDP and 5 nm TSMC process keep power in check, but the core count is what matters for a simulation like Pc Building Simulator, which constantly calculates physics, board voltage, and cooling curves for plural PCs in the scene at once. The CPU's multi-threaded performance from Cinebench R23 is 18,760, single-core 1,930, and Geekbench multi-core 15,371 — the latter is respectable among desktop chips. In the Passmark multi-thread test, it scores 34,470, among other figures. The nearest CPU rivals in avg benchmark score include the AMD Ryzen AI 9 365 (delta +0.1%) and the Intel Core 5 221E (delta -0.2%), which shows tight competition in raw compute.

In game, the 8-core/16-thread count is consistent with the observed behavior: at 1080p Low the CPU can feed the GPU to its max speed (392 FPS), which is impossible for the GPU to bottleneck. At higher resolutions, the GPU loads take over, but the CPU still maintains stable frame pacing even under heavy building simulation. The single-thread performance of 1,930 in Cinebench R23 is only average for a modern chip, but the game's logic tasks are spread across threads efficiently. The Passmark integer math result of 110,295 and floating point of 66,246 confirm the CPU's strong arithmetic capability. In comparison, the GPU's own compute scores are high enough that the CPU rarely halts the pipeline — the 4K Ultra case of 62 FPS is largely due to the card’s shading load.

Overall, while the CPU is not the bottleneck in most of the measured presets, its multi-core strength keeps the simulation fast and smooth at all resolutions. The pairing achieves the 678/3723 rank partly because the CPU's 8 cores are well-matched to the game's compute demands — a 6-core CPU would likely yield lower numbers at 1080p Low, but the 7700 holds its ground there. The single-core and multi-core numbers place it near the top of its category, so the observed FPS are consistent with what the hardware should deliver in a house-simulation environment.
