Pc Building Simulator

Pc Building Simulator presents an interesting case where the CPU and GPU both play significant, yet distinct, roles depending on the resolution and settings. The measured data for the AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4070 Ti combination reveals a system that scales predictably but with some notable inflection points that hint at where the bottleneck shifts. The pairing is a strong one for this simulation title, but the frame rate curves show that neither component is uniformly taxed across all scenarios.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep, but the pattern is not linear across all settings. At Low settings, the average FPS falls from 434 at 1920x1080 to 273.1 at 2560x1440, a reduction of roughly 37%. Moving further to 3840x2160, the average drops to 140.9, which is a 48% decline from the 1440p figure and a 68% drop from 1080p. This massive scaling at Low settings suggests the game is heavily CPU-bound at lower resolutions, where the GPU is not the limiting factor.

At Ultra settings, the scaling is much more moderate. The average FPS at 1080p is 203.2, dropping to 129.5 at 1440p (a 36% decrease) and then to 68.1 at 4K (a 47% decrease from 1440p). The fact that the Ultra preset sees a similar percentage drop between resolutions as Low does suggests that the GPU is becoming the primary constraint at higher graphical loads, but the absolute numbers are still very high.

The data implies that at 1080p, the Ryzen 9 9900X's 12 cores and 24 threads are more than capable of feeding the RTX 4070 Ti, even at Low settings where the GPU has less work to do. The 434 FPS average at 1080p Low is a clear indicator of a CPU-side limit, as the GPU is unlikely to be the ceiling at such a low graphical load. As resolution increases, the GPU's workload grows, and the frame rate scaling becomes more typical of a GPU-bound scenario, especially at Ultra settings where the 4K average of 68.1 FPS is only a fraction of the 1080p result.

CPU Role

The AMD Ryzen 9 9900X, with its 12 cores and 24 threads, is a high-end desktop processor built on the Zen 5 architecture. Its boost clock of 5.60 GHz is a key factor for gaming, and the benchmark results in the fact pack show a strong single-threaded presence. The 3dmark_single_thread score of 1286 and the Cinebench R23 single-core score of 6555 indicate that this chip excels in tasks that rely on a few fast cores, which is often the case in simulation games that have a primary game logic thread.

In Pc Building Simulator, the CPU's role appears to be dominant at lower resolutions. The massive frame rates at 1080p Low (434 FPS) and 1080p Medium (302.8 FPS) are not sustainable by the GPU alone; they are a product of the CPU's ability to process game state updates quickly. The 3dmark_max_threads score of 13929 and the Cinebench R23 multicore score of 46438 show that the CPU also has substantial multi-threaded headroom, but the game likely doesn't scale perfectly across all 24 threads.

The percentileVsAllCpus of 94 places the 9900X in the top tier of processors. Its nearest rival, the AMD Ryzen 9 9900X3D, has an average score that is 0.4% higher, while the Intel Core i7-14700F is 0.7% lower. These are extremely close margins, implying that for this game, the 9900X's raw compute is not a limiting factor. The data suggests that the CPU can push frame rates well beyond what most displays can show, especially at 1080p, and its role is to ensure that the GPU is never starved of data.

GPU Role

The NVIDIA GeForce RTX 4070 Ti is a high-end graphics card with 12 GB of GDDR6X memory and a 192-bit memory bus. Its boost clock of 2610 MHz and the 40.09 TFLOPS FP32 performance are substantial, but the data shows that the card's role becomes more pronounced as resolution and settings increase. The 504.2 GB/s of memory bandwidth is a critical specification for handling the textures and scene data at 4K resolution.

The GPU's percentileVsAllGpus of 85 places it well above the average, but its nearest rivals include the RTX 5090 Mobile (0.6% higher) and the Intel Arc A730M (1.5% higher), which are interesting comparisons given they are not direct desktop equivalents. This suggests that the RTX 4070 Ti is positioned in a competitive performance band. The 3dmark_steel_nomad_dx12 score of 5024 is a modern benchmark that reflects its DirectX 12 capabilities.

At 4K Ultra, the average FPS of 68.1 is the lowest in the measured data, and this is where the GPU is clearly the bottleneck. The frame rate at 4K High (68.6 FPS) is nearly identical to Ultra, indicating that the GPU is hitting a performance ceiling. The transition from 1440p Medium (192.9 FPS) to 4K Medium (98.9 FPS) shows a 49% drop, which is a typical scaling curve for a GPU-bound scenario. The 12 GB of VRAM is likely sufficient for this game, but the memory bus width of 192-bit may limit performance at the highest resolutions compared to wider-bus cards.

FAQ

Q: Why is the frame rate at 1080p Low (434 FPS) so much higher than at 4K Low (140.9 FPS)?

A: The data indicates that at 1080p, the CPU is the limiting component, allowing the GPU to render frames as fast as the processor can issue draw calls. At 4K, the GPU's workload increases significantly, making it the primary bottleneck, hence the large drop in average FPS.

Q: Is the CPU or GPU more important for this game at 1440p?

A: At 1440p, the scaling between Low (273.1 FPS) and Ultra (129.5 FPS) settings suggests a balance. The CPU still provides high frame rates at Low, but the GPU's influence grows as settings increase. The data shows a 53% drop from Low to Ultra, indicating both components are relevant.

Q: What is the best resolution to play at for high refresh rate monitors?

A: Based on the measured data, 1920x1080 at High settings yields an average of 217 FPS, which is ideal for a 240 Hz monitor. At 2560x1440 High, the average FPS of 134.9 would be suitable for a 144 Hz display.

Q: Does the RTX 4070 Ti's 12 GB VRAM cause any issues at 4K?

A: The frame rate data does not show any anomalous drops that would suggest VRAM capacity issues. The 4K Ultra average of 68.1 FPS is consistent with the GPU's compute limits, not a memory shortage.

Q: How does the Ryzen 9 9900X compare to its closest rival in terms of CPU benchmarks?

A: The AMD Ryzen 9 9900X3D has an average benchmark score that is 0.4% higher, while the Intel Core i7-14700F is 0.7% lower. These differences are minimal, suggesting the 9900X provides comparable performance to its nearest competitors.

Q: Is the frame rate at 4K Ultra playable?

A: The 68.1 FPS average at 3840x2160 Ultra is above the 60 FPS threshold for smooth gameplay, making it playable on a standard 60 Hz monitor, though not ideal for high refresh rate gaming.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are 434 FPS on Low, 302.8 FPS on Medium, 217 FPS on High, and 203.2 FPS on Ultra. The jump from Low to Medium is a 30% reduction, while the drop from High to Ultra is only 6%, indicating diminishing returns from the highest settings.

At 2560x1440, the averages are 273.1 FPS on Low, 192.9 FPS on Medium, 134.9 FPS on High, and 129.5 FPS on Ultra. The scaling from Medium to High is a 30% drop, but High to Ultra is again a small 4% reduction, showing that the Ultra preset has a minimal impact at this resolution.

At 3840x2160, the averages are 140.9 FPS on Low, 98.9 FPS on Medium, 68.6 FPS on High, and 68.1 FPS on Ultra. The most significant drop is from Medium to High, which is a 31% decrease. The High and Ultra settings are nearly identical, with a difference of just 0.5 FPS, suggesting the GPU is fully saturated at this point.

Settings Recommendations

For the best experience at 1920x1080, the High preset offers an average of 217 FPS, which is a 14 FPS improvement over Ultra (203.2 FPS) while presumably being less demanding on the system. The Low preset's 434 FPS is excessive for any standard display, making High the optimal balance of visual quality and performance.

At 2560x1440, the High preset again appears to be the sweet spot. The 134.9 FPS average is sufficient for high refresh rate gaming, and it is only 5.4 FPS lower than the Ultra preset (129.5 FPS). The Medium preset at 192.9 FPS is also viable, but High offers better visual fidelity with a modest performance cost.

For 4K, the choice is between High (68.6 FPS) and Ultra (68.1 FPS). Since the performance difference is negligible, selecting Ultra is recommended for the best visual quality, as the average frame rate remains above 60 FPS. The Medium preset at 98.9 FPS is also an option for those who prefer higher frame rates, but the gap to High is significant.
