Pc Building Simulator

The AMD Ryzen 9 7900X paired with the AMD Radeon RX 9070 delivers a robust performance profile in Pc Building Simulator, a simulation title that scales predictably with hardware resources. The data reveals a system that is GPU-bound at higher resolutions but exhibits substantial headroom at 1080p, where the processor’s multi-threading capabilities come to the forefront. This analysis breaks down the measured frame rates, component roles, and ranking position of this combination, providing a clear picture of its strengths and limitations.

Resolution Scaling

The frame rate data for this combo shows a classic pattern of diminishing returns as resolution increases, clearly indicating the GPU as the primary performance limiter at higher pixel counts. At 1080p with High settings, the system delivers an average of 173 FPS. Moving to 1440p at the same High preset, the average drops to 109 FPS, a substantial 37% decrease. Scaling further to 4K at High settings, the average falls to 57 FPS, which is a 67% reduction from the 1080p figure. This precipitous drop highlights the significant increase in pixel shading workload that the Radeon RX 9070 must handle as resolution scales.

The trend is even more pronounced at the Low settings tier. The system achieves a very high 346 FPS average at 1080p, which drops to 219 FPS at 1440p (a 36.7% reduction) and finally to 114 FPS at 4K (a massive 67.1% reduction from 1080p). This pattern indicates that while the CPU is capable of feeding frames at lower resolutions, the GPU becomes increasingly the limiting component as the pixel count rises.

Examining the Medium settings tier, which includes min and max FPS data, reveals a similar scaling pattern. At 1080p, the average is 245 FPS with a min of 209 FPS and a max of 282 FPS. At 1440p, the average drops to 155 FPS, with a min of 132 FPS and max of 178 FPS. At 4K, the average is 81 FPS, with a min of 69 FPS and a max of 93 FPS. The 4K figure represents a 66.9% reduction from the 1080p average, reinforcing the GPU-bound nature of the title at this resolution.

The performance gap between 1080p and 1440p is consistently around 36-40%, while the gap between 1440p and 4K is roughly 43-48%. This indicates that the scaling is not linear, with the 4K resolution imposing a disproportionately heavier load. The data clearly shows that for users prioritizing high refresh rates, 1080p is the resolution of choice, while 4K is only viable for those who accept 60 FPS or lower, particularly on High or Ultra presets.

GPU Role

The AMD Radeon RX 9070 is the primary driver of these results, particularly at 1440p and 4K. Its 16 GB of GDDR6 memory on a 256-bit bus provides a 644.6 GB/s bandwidth, which is a critical asset for a game like this that manages extensive scene data. The 4K resolution performance, with its high memory demands, is where the GPU's memory subsystem is likely to be a key factor. The RX 9070’s boost clock of 2520 MHz and game clock of 2070 MHz are consistent with its performance class, as indicated by its 69th percentile ranking among all GPUs.

The GPU's benchmark scores, such as the 25381 in Passmark G3D and 14737 in Passmark GPU Compute, position it as a mid-to-high-tier performer. Its nearest rivals, including the NVIDIA GeForce RTX 2080 SUPER and the AMD Radeon RX 6800S, are within a 1.2% to 1.1% margin of its average score, indicating that the RX 9070's performance is closely matched with these older or mobile parts. This suggests that in this specific simulation, the GPU's raw compute and rasterization capabilities are sufficient for high frame rates at 1080p and 1440p, but are the limiting factor at 4K Ultra.

The 4K Ultra preset yields 54 FPS average, while the High preset at 4K gives 57 FPS. This small difference suggests that Ultra settings at 4K place a significant load on the GPU, and the RX 9070 is operating at its limits. In contrast, the 1080p Ultra setting achieves 165 FPS, a very high result that demonstrates the GPU has significant headroom at this resolution.

How This Combo Ranks

In the database of tested hardware combinations, this pairing of the Ryzen 9 7900X and the Radeon RX 9070 ranks 1082nd out of 3723 tested combos. This places it in the 71st percentile of all tested combinations. This is a strong ranking, indicating that the system is capable of delivering above-average performance in this specific game compared to other CPU-GPU pairs tested. The Ryzen 9 7900X’s own performance metrics contribute significantly to this ranking, as it sits in the 91st percentile of all CPUs, with an average benchmark score of 53288.

The CPU’s nearest rivals include the AMD EPYC 7313P, which is 0.2% behind, and the Intel Xeon Phi 7290, which is 0.3% ahead. This indicates that the Ryzen 9 7900X is positioned among the top tier of processors. The GPU’s ranking is lower, in the 69th percentile, and its nearest rivals are all within a 1.2% delta of its average score. This suggests that while the CPU is a top-tier part, the GPU is a more mainstream component, which is likely why the combo’s overall rank is in the 71st percentile rather than higher. The CPU’s strength is not fully utilized in this game, as the GPU limits performance at higher resolutions.

Measured FPS Breakdown

The measured frame rates provide a complete picture of the system's performance across 1080p, 1440p, and 4K resolutions, and across Low, Medium, High, and Ultra settings. At 1920x1080, the average FPS values are: Low 346, Medium 185, High 173, and Ultra 165. The Medium setting shows a min of 209 and a max of 282 FPS, indicating some frame time variance.

At 2560x1440, the averages are Low 219, Medium 155, High 109, and Ultra 104. The Medium setting min and max are 132 and 178 FPS, respectively. The 1440p High and Ultra averages are quite close, with only a 5 FPS difference, suggesting that the GPU is the primary limiter at this resolution.

At 3840x2160, the averages are Low 114, Medium 81, High 57, and Ultra 54. The Medium settings min and max are 69 and 93 FPS. The 4K High and Ultra presets both yield average frame rates below 60 FPS, indicating that this configuration cannot maintain a smooth 60 FPS experience at the highest visual quality settings.

Settings Recommendations

Based on the measured data, the best experience for a 60 Hz display at 4K would be the Medium preset, which delivers an average of 81 FPS, with a minimum of 69 FPS. This is the only 4K preset that stays above the 60 FPS threshold, and it provides a stable frame rate. For users with 1440p 165 Hz monitors, the High preset at 109 FPS average is a suitable choice, offering a good balance between visual quality and smoothness. The Ultra preset at 104 FPS would also be viable, but the extra 5 FPS from High might be an acceptable trade-off for the slight visual improvement.

At 1080p, the Medium preset at 185 FPS and High at 173 FPS are both excellent for high refresh rate displays. The Ultra preset at 165 FPS is also very playable. For the absolute highest frame rates, the Low preset at 346 FPS is available, but this is only for users who prioritize performance over visual fidelity. The data suggests that for most users, the Medium or High presets at 1440p will offer the most balanced experience, while the 4K Medium preset is the only 4K option that can maintain a 60 FPS average.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on Zen 4 architecture, with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. It has 64 MB of shared L3 cache and supports DDR5 memory with a dual-channel bus. In this game, the CPU's role is more pronounced at lower resolutions. At 1080p, the system can achieve 346 FPS on Low, which is a high frame rate that is likely CPU-bound. The 12 cores and 24 threads of the Ryzen 9 7900X are capable of handling the game's simulation and AI tasks with ease, and the high clock speeds are beneficial for the single-threaded performance that many simulation games rely on.

The CPU's benchmark scores, such as 29300 in Cinebench R23 multicore and 2016.5 in single-core, are high, ranking it in the 91st percentile of all CPUs. This indicates that the CPU is not a bottleneck in this game, and its performance is more than sufficient to keep up with the GPU, especially at 1080p. The CPU’s nearest rivals, such as the Intel Core i7-14700F, are within a 0.6% delta of its average score, confirming its top-tier status. The data suggests that the CPU is not the limiting factor in most test cases, and the GPU is the component that dictates performance at higher resolutions.
