Pc Building Simulator

Pc Building Simulator presents an interesting case study for the AMD Ryzen 5 5500 and NVIDIA GeForce RTX 5080 combination. As a simulation title focused on system assembly, its performance profile differs from typical action games, with the data revealing a significant bottleneck imposed by the processor. The benchmark results, measured across three resolutions and four quality presets, show a pairing where the GPU's considerable power is often left untapped, making this a prime example of CPU-limited performance in a non-standard gaming workload.

Resolution Scaling

The measured FPS data shows a clear and predictable pattern of performance degradation as resolution increases, but the degree of change is heavily influenced by the graphics settings. At the High preset, the average frame rate drops from 237.5 FPS at 1920x1080 to 157.4 FPS at 2560x1440, and finally to 85.2 FPS at 3840x2160. This represents a substantial 64% reduction in frame rate from 1080p to 4K, indicating that at higher resolutions, the rendering load on the GPU becomes a more significant factor. However, the story is different at the Low preset. Here, the frame rate only falls from 306.5 FPS at 1080p to 263.9 FPS at 1440p, and then to 164.7 FPS at 4K, a 46% drop.

This discrepancy between presets is the key to understanding the limiting component. At Low settings, the GPU has less work to do, but the frame rate at 1080p is still capped at 306.5 FPS, suggesting that the CPU is the primary constraint. The data indicates that the RTX 5080, with its 16 GB of GDDR7 memory and 960.0 GB/s bandwidth, is more than capable of handling the geometry and texture work at lower resolutions. The scaling from 1440p to 4K at Low settings (a 37.6% drop) is more pronounced than the scaling from 1080p to 1440p (a 13.9% drop), showing the GPU starting to become the bottleneck only when pixel count increases dramatically. The Ultra preset tells a similar story to High, with frame rates of 236.3, 148.2, and 78.6 FPS across the three resolutions, respectively.

How This Combo Ranks

In the context of all tested combinations for Pc Building Simulator, this specific pairing of the AMD Ryzen 5 5500 and NVIDIA GeForce RTX 5080 achieves a combo rank of 145 out of 1769. This places it in the top 8.2% of all tested configurations, which is a strong showing. However, given the individual components, this ranking might seem lower than expected. The RTX 5080 sits in the 89th percentile of all GPUs, while the Ryzen 5 5500 is in the 79th percentile of all CPUs. The combo's rank, while high in absolute terms, is not as high as the GPU's percentile, reinforcing the idea that the CPU is holding the system back from achieving its full potential in this specific game.

The performance data for the CPU further contextualizes this. The Ryzen 5 5500 has an average benchmark score of 20875 and is nearly identical in performance to its nearest rivals, including the Intel Core i5-12500 (deltaPct of -0.1%) and the AMD Ryzen 5 PRO 4655GE (deltaPct of -0.1%). This means the CPU is a solid, mid-range performer, but it is not a top-tier part. When paired with a flagship-class GPU like the RTX 5080, the combination's overall rank is dictated by the weaker link, which in this case is the processor, preventing the combo from ranking higher among the 1769 tested configurations.

GPU Role

The NVIDIA GeForce RTX 5080 is a powerhouse on paper, built on the Blackwell 2.0 architecture with a 5 nm process. It features 10752 shading units, 336 texture mapping units, and 112 render output units. Its 16 GB of GDDR7 memory on a 256-bit bus provides a massive 960.0 GB/s of bandwidth. The card's base clock is 2295 MHz with a boost clock of 2617 MHz, and it has a TDP of 360 W. These specifications are more than sufficient for any modern game, including a simulation title like Pc Building Simulator.

The benchmark scores for the GPU are equally impressive. It achieves a passmark_g3d score of 36565 and a 3dmark_steel_nomad_dx12 score of 8637. Its average benchmark score is 59188, placing it in the 89th percentile of all GPUs. Its nearest rivals, such as the Intel Arc A570M (deltaPct of 1.6%) and the Intel Arc Pro A60 (deltaPct of -1.9%), are far less powerful. In Pc Building Simulator, the GPU's role is to render the 3D workspace, the components, and the case. The data shows that at 4K Ultra, the GPU is finally being pushed, with the frame rate dropping to 78.6 FPS. This indicates that the game is not heavily reliant on the GPU’s raw compute power or its advanced features, as even a less capable card might produce similar results at lower resolutions if the CPU were not the limiting factor.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at the combo's performance across the board. At 1920x1080, the frame rates are exceptionally high, indicating a severe CPU bottleneck. The Low preset yields an average of 306.5 FPS, which is the highest recorded for this combo. The Medium and High presets produce 272.3 FPS and 237.5 FPS, respectively, while the Ultra preset is close behind at 236.3 FPS. The small difference between High and Ultra (1.2 FPS) suggests that the additional graphical effects at Ultra are being handled by the GPU without impacting the CPU-limited frame rate.

Moving to 2560x1440, the frame rates remain very high but show more differentiation. The Low preset averages 263.9 FPS, while Medium, High, and Ultra produce 224 FPS, 157.4 FPS, and 148.2 FPS, respectively. The spread between Low and Ultra is now 115.7 FPS, showing the GPU beginning to have a more significant impact on performance. At 3840x2160, the GPU's role becomes dominant. The Low preset still manages an average of 164.7 FPS, but the Medium preset drops to 118.5 FPS. The High and Ultra presets yield 85.2 FPS and 78.6 FPS, respectively. The frame rate at 4K Ultra, while still playable, is a far cry from the 236.3 FPS seen at 1080p Ultra, clearly demonstrating the increased rendering load at higher resolutions.

CPU Role

The AMD Ryzen 5 5500 is a 6-core, 12-thread processor based on the Zen 3 architecture (Codenamed Cezanne) and manufactured on a 7 nm process. It has a base clock of 3.60 GHz and a boost clock of 4.20 GHz, with a 16 MB L3 cache. Its benchmark scores are solid for a mainstream chip, with a Cinebench R23 multicore score of 16429 and a single-core score of 2319. While these numbers are respectable, the data from Pc Building Simulator indicates that the game's performance is heavily dependent on single-threaded CPU performance, which this chip provides in moderation.

The most compelling evidence for the CPU bottleneck is the frame rate scaling at 1080p. The difference between the Low (306.5 FPS) and Ultra (236.3 FPS) presets is only 70.2 FPS, despite the significant increase in GPU workload. If the GPU were the limiting factor, we would expect to see a much larger difference, as the Ultra preset would demand substantially more from the graphics card. The fact that the frame rate remains so high even at Low settings suggests that the CPU is unable to feed the GPU with enough draw calls to push the frame rate higher. The Ryzen 5 5500's performance, while close to its rivals like the Intel Core i5-12500, caps the system's potential in this simulation title, preventing the RTX 5080 from fully stretching its legs until the resolution is increased to 4K.
