The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture using a 5 nm process at TSMC, with 35,800 million transistors on a 294 mm² die. Its core configuration includes 5,888 shading units, 184 texture mapping units, and 64 ROPs, alongside 46 ray tracing cores and 184 tensor cores. The GPU’s base clock is 1,920 MHz with a boost clock of 2,475 MHz, producing 29.15 TFLOPS of FP32 compute power.

Benchmark results place this GPU in the 81st percentile of all graphics cards, with an average score of 37,648. In the context of Pc Building Simulator, the RTX 4070’s 12 GB of GDDR6X memory and 504.2 GB/s bandwidth prove sufficient even at the highest settings. The data shows that at 4K Ultra, the average FPS is 58, which is only 3 FPS below the 4K High result of 61 FPS — indicating that the GPU is approaching its performance ceiling at that resolution. However, at 1440p and 1080p, the GPU has ample headroom, with 4K Low producing 121 FPS and 1440p Low reaching 232 FPS.

The GPU’s pixel rate of 158.4 GPixel/s and texture rate of 455.4 GTexel/s are relevant for this simulation title, which renders detailed 3D scenes of PC components and cases. The 192-bit memory bus, while narrower than higher-tier cards, still delivers the bandwidth needed to maintain smooth frame rates. The RTX 4070’s nearest rival, the RTX 4080 Mobile, is 1.3% faster in average benchmark score, but the desktop RTX 4070’s performance in this game remains strong across all measured settings.

Resolution Scaling

The measured FPS data reveals a clear pattern of scaling from 1080p to 4K, with the most dramatic drop occurring at the Ultra preset. At 1080p Ultra, the system averages 175 FPS; at 1440p Ultra, this falls to 110 FPS (a 37% reduction); and at 4K Ultra, it drops to 58 FPS (a 67% reduction from 1080p). This steep decline indicates that at Ultra settings, the GPU becomes the limiting factor as pixel count increases.

For the Low preset, the scaling is even more pronounced in percentage terms but results in higher absolute frame rates. At 1080p Low, the average is 352 FPS; at 1440p Low, it drops to 232 FPS (34% lower); and at 4K Low, it reaches 121 FPS (66% lower than 1080p). The fact that 4K Low still produces 121 FPS suggests that the CPU, with its 96 MB L3 cache and 4.50 GHz boost clock, is capable of feeding the GPU efficiently even at lower graphical loads.

The Medium preset shows the only complete min/max data in the pack. 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 with a min of 140 and max of 189. At 4K Medium, the average is 86 FPS with a min of 73 and max of 99. The narrowing of the min-to-max range at higher resolutions (from 78 FPS spread at 1080p to 26 FPS spread at 4K) suggests that frame pacing becomes more consistent as the GPU becomes more heavily utilized.

The High preset follows a similar trend: 184 FPS at 1080p, 116 FPS at 1440p, and 61 FPS at 4K. The percentage drops from 1080p to 4K are 67% for Ultra, 67% for High, 67% for Medium, and 66% for Low. This near-uniform scaling across presets indicates that the system’s performance is primarily GPU-bound at higher resolutions, while the CPU’s strong single-thread performance (PassMark single-thread score of 3,494) keeps 1080p frame rates exceptionally high.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all presets. The Low preset achieves an average of 352 FPS, which is the highest measured value in the entire dataset. Medium settings produce 260 FPS on average, with a minimum of 221 and maximum of 299 FPS. High settings yield 184 FPS, while Ultra settings still manage 175 FPS. The difference between High and Ultra at 1080p is only 9 FPS, suggesting that the Ultra preset’s additional graphical effects have a relatively minor impact at this resolution.

At 2560x1440, the frame rates remain high but show a more noticeable gap between presets. Low settings average 232 FPS, which is a 34% drop from the 1080p Low result. Medium settings average 164 FPS, with a minimum of 140 and maximum of 189 FPS. High settings deliver 116 FPS, and Ultra settings produce 110 FPS. The gap between High and Ultra narrows further to just 6 FPS, indicating that the Ultra preset’s additional load is well-managed by the RTX 4070’s 12 GB VRAM and 504.2 GB/s bandwidth.

At 3840x2160, the system’s performance becomes more constrained. Low settings average 121 FPS, which is still highly playable. Medium settings average 86 FPS, with a minimum of 73 and maximum of 99 FPS. High settings drop to 61 FPS, and Ultra settings fall to 58 FPS. The marginal difference between High and Ultra at 4K (only 3 FPS) suggests that the GPU is hitting a performance wall, likely due to the combination of pixel throughput and memory bandwidth limitations. The RTX 4070’s 158.4 GPixel/s pixel rate becomes the bottleneck at this resolution with higher settings.

The data shows that the Medium preset at 4K, with its 86 FPS average and 73 FPS minimum, offers the best balance of visual quality and performance for players targeting 4K on this hardware. The Low preset’s 121 FPS average at 4K demonstrates that the CPU is not limiting performance, as even at the lowest graphical settings, the frame rate remains well above 100 FPS.

In Pc Building Simulator, the CPU’s impact is most visible at lower resolutions and settings. At 1080p Low, the system achieves 352 FPS, which is a strong indicator that the CPU is not a bottleneck. Even at 4K Low, the 121 FPS result suggests the CPU can feed the GPU adequately. The CPU’s 4.50 GHz boost clock and 96 MB L3 cache help maintain high frame rates in simulation titles, which often involve complex logic and scene management. The PassMark physics score of 2,779 and floating-point math score of 43,594 further support the CPU’s capability in handling the computational load of a building simulator.

The CPU’s memory support includes DDR5 with dual-channel configuration, providing 83.2 GB/s of bandwidth. This, combined with the 96 MB L3 cache, reduces the frequency of memory accesses, which can improve frame time consistency. The combo rank of 703 out of 3,002 in this game places this CPU-GPU pairing in the top 23% of tested combinations, indicating that the 7500X3D contributes positively to the overall experience.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. For players with 1080p displays, the Ultra preset at 175 FPS provides the best visual experience while still maintaining frame rates far above the refresh rate of most monitors. The High preset at 184 FPS offers a marginal 9 FPS improvement but with reduced graphical fidelity, making Ultra the recommended choice at 1080p.

For 1440p displays, the High preset at 116 FPS offers a good balance, but the Ultra preset at 110 FPS is also viable. The difference between these two is only 6 FPS, so players with high-refresh-rate 1440p monitors may prefer High for the slight FPS boost, while those prioritizing visuals can choose Ultra without significant penalty. The Medium preset at 164 FPS is the best option for competitive play or for users targeting 144Hz or higher refresh rates.

At 4K, the Medium preset at 86 FPS is the clear recommendation. It provides a comfortable margin above 60 FPS, with a minimum of 73 FPS, ensuring smooth gameplay even in demanding scenes. The High and Ultra presets at 61 FPS and 58 FPS respectively are playable but hover near the 60 FPS threshold, making them riskier for maintaining consistent frame pacing. The Low preset at 121 FPS is excessive for 4K and sacrifices too much visual quality, as the Medium preset’s min FPS of 73 is already well above typical playability thresholds.

Across all resolutions, the Medium preset offers the most balanced experience, with min FPS data available only for this preset: 221 FPS at 1080p, 140 FPS at 1440p, and 73 FPS at 4K. This consistency in minimum frame rates suggests that Medium provides the most stable performance, making it the safest recommendation for users who prioritize smoothness over absolute visual fidelity. The system’s overall performance, with its 89th percentile CPU and 81st percentile GPU, comfortably handles this simulation title at any resolution, but the data indicates that 4K Ultra is the only configuration that falls below 60 FPS, at 58 FPS average.
