Pc Building Simulator

Pc Building Simulator is a simulation title that, despite its desktop-building theme, places a surprisingly heavy load on the GPU at higher resolutions. The data for the AMD Ryzen 7 5800X3D and NVIDIA GeForce RTX 5090 combo shows a clear pattern: the RTX 5090 is the dominant component, with the CPU providing ample headroom to keep frame rates high even when the graphics card is fully saturated.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep, which is typical for a game where visual fidelity scales directly with GPU workload. At Ultra settings, the average FPS falls from 250.2 at 1920x1080 to 161.5 at 2560x1440, a reduction of roughly 35%. Pushing further to 3840x2160 brings the average down to 83.4 FPS, which is a 67% drop from the 1080p figure. This indicates that the RTX 5090 is the limiting factor at 4K, as the CPU’s performance is not able to compensate for the massive increase in pixel count.

At Low settings, the scaling is even more dramatic. The 1080p result of 325.5 FPS drops to 280.1 at 1440p and then to 178.2 at 4K. The gap between 1440p and 4K at Low settings is 101.9 FPS, which is larger than the gap at Ultra settings (78.1 FPS). This suggests that at lower graphical presets, the GPU is still the bottleneck, but the CPU’s role becomes more significant as the frame rate ceiling rises. The 1080p Low figure of 325.5 FPS is the highest recorded for this combo, showing that the Ryzen 7 5800X3D can push the RTX 5090 to its limits when the GPU is not constrained by resolution.

The data implies that 1440p is the sweet spot for this pairing. At High settings, the 168.5 FPS average is well above the 144Hz refresh rate common on many monitors, and even Ultra settings at 1440p maintains a 161.5 FPS average. For 4K gaming, the RTX 5090’s raw power is evident, but the 83.4 FPS Ultra result means that users targeting 4K will need to adjust settings to maintain high refresh rates.

GPU Role

The NVIDIA GeForce RTX 5090 is the clear workhorse in this configuration. With 32 GB of GDDR7 memory on a 512-bit bus, it provides a memory bandwidth of 1.79 TB/s, which is more than sufficient for a simulation game that may load large textures and assets. The GPU’s 21760 shading units and 176 ROPs are key to its performance. The boost clock of 2407 MHz helps sustain high frame rates, but the sheer number of cores is what allows it to handle the rendering load at 4K.

Benchmark results place the RTX 5090 in the 94th percentile among all GPUs, with an average benchmark score of 84306. Its nearest rival, the NVIDIA GeForce RTX 5090 D, scores 84241, a delta of 0.1%. This puts the two cards in a statistical tie, meaning the performance difference is negligible in synthetic tests. The AMD Radeon PRO W6600, which scores 83209, is 1.3% behind, showing that the RTX 5090 holds a small but measurable lead over a workstation-focused card.

The GPU’s performance in Pc Building Simulator is consistent with its overall standing. At 4K Ultra, the 83.4 FPS average is respectable for a simulation title, and the fact that it can nearly double that at 1440p High settings (168.5 FPS) shows that the card is not being held back by any other component in the system. The 32 GB VRAM pool is a future-proofing asset, as it means the game will not be VRAM-limited at any resolution or setting combination tested.

CPU Role

The AMD Ryzen 7 5800X3D is a Zen 3 part with 8 cores and 16 threads, running on the AM4 socket. Its base clock of 3.40 GHz boosts to 4.50 GHz, and its 96 MB of shared L3 cache is a defining feature for gaming performance. The CPU’s benchmark scores are strong, with a Cinebench R23 multicore result of 24063 and a single-core score of 3397. These numbers place it in the 83rd percentile among all CPUs, with an average benchmark score of 26574.

Its nearest rival, the Intel Core i9-11900K, scores 26546, a delta of 0.1%, meaning the two are effectively equal in synthetic tests. The AMD Ryzen 5 7600 is 0.2% behind with a score of 26617, while the Intel Core i9-12900HK is 0.4% behind at 26672. This puts the 5800X3D in a tight pack of CPUs that all perform within a fraction of a percent of each other, which is notable for a part that is listed as end-of-life.

In Pc Building Simulator, the CPU’s role is to feed the RTX 5090 enough data to keep it busy. At 1080p Low settings, the 325.5 FPS average indicates that the CPU is not a bottleneck, as the frame rate is high enough to saturate most displays. The single-thread performance, evidenced by a Geekbench single-core score of 2116, is crucial for simulation games that often rely on a single main thread for game logic. The 8-core, 16-thread layout provides ample multi-threading capacity for background tasks and asset streaming.

How This Combo Ranks

Among 1769 tested combinations, this pairing of the AMD Ryzen 7 5800X3D and NVIDIA GeForce RTX 5090 ranks 79th. This is a strong result, placing it in the top 4.5% of all tested combos. The ranking reflects the balance between the two components: the CPU is not holding back the GPU, and the GPU is powerful enough to maximize the CPU’s potential.

This ranking is particularly impressive given the CPU’s age. The Ryzen 7 5800X3D was released in April 2022, and it is still able to compete with newer parts like the Ryzen 5 7600 and the Core i9-12900HK, both of which are within 0.4% of its average benchmark score. The combination of the 5800X3D’s large cache and the RTX 5090’s massive compute throughput creates a system that is well-suited for high-refresh-rate gaming at 1440p and solid performance at 4K.

The rank of 79 suggests that there are 78 other combos that perform better in this specific game. These are likely to include newer CPUs with higher single-thread performance or more cores, but the data shows that the 5800X3D is still a viable choice for a top-tier GPU like the RTX 5090.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce an average of 325.5 FPS, while Medium settings yield 283.6 FPS. High and Ultra settings are nearly identical, with 249.5 and 250.2 FPS respectively. This suggests that at 1080p, the CPU is the primary limiter, as increasing GPU load from High to Ultra has almost no effect on frame rate.

Moving to 2560x1440, the GPU becomes more involved. Low settings still achieve a high 280.1 FPS, but Medium drops to 239.2 FPS. High settings average 168.5 FPS, and Ultra settings fall to 161.5 FPS. The gap between High and Ultra at 1440p is only 7 FPS, showing that the GPU has enough headroom to handle the extra visual effects without a major performance hit.

At 3840x2160, the RTX 5090 is fully utilized. Low settings produce 178.2 FPS, which is still very playable. Medium settings drop to 126.8 FPS, while High settings average 90.2 FPS. Ultra settings bring the average down to 83.4 FPS. The scaling from High to Ultra at 4K is a reduction of 6.8 FPS, which is a modest penalty for the increased visual quality. This data shows that the RTX 5090 is capable of handling 4K in this game, but users targeting 120 FPS or higher will need to use Medium or Low settings.
