Pc Building Simulator

Pc Building Simulator presents an interesting case study for the AMD Ryzen 5 5600F and NVIDIA GeForce RTX 5090 combination. While the GPU is a top-tier component, the game's simulation-heavy nature and the CPU's mid-range standing create a specific performance profile that differs from typical AAA shooters. This analysis examines the measured FPS data to understand how this pairing behaves across resolutions and settings, and what it reveals about the underlying hardware balance.

How This Combo Ranks

The Ryzen 5 5600F with the RTX 5090 combination is ranked 345th out of 3002 tested combos for Pc Building Simulator. This places it in the top 11.5% of all configurations tested, which is a strong result but not near the absolute top. The rank indicates that while this combo delivers high frame rates, there are many other pairings—likely with more powerful CPUs—that achieve even better results in this specific title.

The CPU's percentile ranking of 85 versus all CPUs suggests it is a solid performer, but the fact that it sits at rank 345 rather than higher in the game-specific list points to a bottleneck. The RTX 5090 is in the 92nd percentile of all GPUs, meaning it is faster than 92% of other graphics cards. When a GPU this powerful is paired with a CPU that is only in the 85th percentile, the game's simulation logic—which relies heavily on CPU single-thread performance—can become the limiting factor.

Looking at the CPU's nearest rivals, the data shows how close the mid-range field is. The Intel Core Ultra 5 225 has an average score of 36938, which is a 0% delta from the Ryzen 5 5600F's average of 36945. The AMD Ryzen 5 5500X3D is only -0.2% behind, and the AMD Ryzen AI 7 PRO 450 is -0.4% behind. Even the Intel Core i9-12900T, a higher-tier part, is just -0.5% off. This clustering means that for a simulation title like Pc Building Simulator, the choice between these CPUs would likely yield very similar results, and the RTX 5090's massive compute power is not being fully utilized by any of them.

The GPU's nearest rivals are a different story. The NVIDIA Tesla P100 PCIe 16 GB scores 79605, which is a 0.3% delta from the RTX 5090's average of 79842. The Tesla P100 PCIe 12 GB is 0.6% behind, and the AMD Radeon RX 6850M XT is 1.1% behind. The AMD Radeon Pro Vega 64X is -1.4% ahead. These are professional or mobile workstation cards, which highlights that the RTX 5090's raw benchmark numbers are in a league of their own for gaming, yet the game-specific rank of 345 shows that raw GPU power does not translate to top-tier performance in this simulation.

GPU Role

The NVIDIA GeForce RTX 5090 is a monster of a graphics card on paper. It features 32 GB of GDDR7 memory on a 512-bit bus, providing a massive 1.79 TB/s of memory bandwidth. The card clocks at 2017 MHz base and boosts to 2407 MHz, with memory running at 1750 MHz (28 Gbps effective). It has 21760 shading units and a pixel rate of 423.6 GPixel/s.

However, the measured FPS data reveals that the RTX 5090 is often not the bottleneck in Pc Building Simulator. At 4K Ultra settings, the combo manages only 84 FPS average, which is a high number for most games but relatively low for a card of this caliber. The 4K High setting yields 88 FPS, and 4K Medium reaches 124 FPS. The jump to 4K Low gives 176 FPS. These numbers show a clear pattern: the GPU can push far more frames at lower settings, which means the CPU is holding it back at higher settings where more complex simulation logic is required.

The GPU's performance in synthetic benchmarks backs this up. Its Passmark G3D score is 39650, and its 3DMark Steel Nomad DX12 score is 18355. In Geekbench, it scores 334370 in OpenCL and 376728 in Vulkan. These are top-tier numbers, but in Pc Building Simulator, the frame rates at 4K Ultra and High are nearly identical (84 vs 88 FPS), which suggests a hard CPU limit rather than a GPU rendering limit. The RTX 5090's massive memory bandwidth and 32 GB VRAM are largely irrelevant in this game because the simulation does not require that kind of texture throughput.

FAQ

Q: Why does the 4K Ultra frame rate (84 FPS) barely differ from the 4K High frame rate (88 FPS)?

A: This small difference of 4 FPS indicates that both settings are hitting a similar performance ceiling. The data shows that the RTX 5090 is capable of much higher frame rates at lower settings, as seen with the 4K Low average of 176 FPS. The plateau between High and Ultra suggests the CPU's single-thread performance is the limiting factor, as the GPU has plenty of headroom.

Q: Is the RTX 5090 a good match for this CPU in this game?

A: Benchmark results indicate a mismatch. The GPU ranks in the 92nd percentile of all GPUs, while the CPU ranks in the 85th percentile. In Pc Building Simulator, the combo ranks 345th out of 3002, which is good but not top-tier. The CPU's Passmark single-thread score of 2872 is moderate, and the game appears to be CPU-bound at higher settings, meaning the RTX 5090's potential is not fully realized.

Q: What is the best resolution to play at with this combo?

A: The data shows that at 1440p, the combo delivers 160 FPS on Ultra and 242 FPS on Low. At 1080p, those numbers are 214 FPS on Ultra and 282 FPS on Low. For a smooth experience in a simulation game, the 1440p Ultra setting at 160 FPS offers a good balance between visual quality and frame rate, as it is well above the 144 Hz refresh rate commonly found on monitors.

Q: How does the CPU's single-thread performance affect the game?

A: The Ryzen 5 5600F has a Passmark single-thread score of 2872. In a simulation game like Pc Building Simulator, which relies on physics and logic calculations, this score is crucial. The fact that 4K Ultra (84 FPS) and 4K High (88 FPS) are so close, while 4K Low jumps to 176 FPS, suggests that the CPU is the bottleneck when the game's simulation complexity increases with higher settings.

Q: Is 32 GB of VRAM necessary for this game?

A: The data shows that the RTX 5090's 32 GB GDDR7 memory is not a contributing factor to the measured performance. The frame rates are limited by CPU performance, not video memory capacity. In Pc Building Simulator, even the 4K Ultra setting does not appear to stress the GPU's memory, as the bottleneck is clearly elsewhere.

Q: How does this combo compare to the CPU's nearest rivals?

A: The CPU's nearest rivals are all within 0.5% of its average benchmark score of 36945. The Intel Core Ultra 5 225 is at 0%, the AMD Ryzen 5 5500X3D is at -0.2%, and the AMD Ryzen AI 7 PRO 450 is at -0.4%. This means swapping the 5600F for any of these CPUs would likely result in nearly identical FPS in this game, reinforcing that the CPU is the limiting factor, not the specific model.

Measured FPS Breakdown

The measured FPS data provides a clear picture of how the combo scales across resolutions and settings. At 1080p, the average frame rates are: 282 FPS on Low, 248 FPS on Medium, 218 FPS on High, and 214 FPS on Ultra. The Medium setting shows a min of 211 FPS and a max of 285 FPS, indicating some variance but generally smooth performance. The drop from Low to Medium is 34 FPS, while the drop from Medium to High is 30 FPS. Interestingly, the drop from High to Ultra is only 4 FPS (218 to 214), which shows that the Ultra preset adds little graphical load in this game, likely because the CPU is already saturated.

At 1440p, the numbers are: 242 FPS on Low, 213 FPS on Medium, 168 FPS on High, and 160 FPS on Ultra. The Medium preset has a min of 181 FPS and a max of 245 FPS. The scaling from Low to Medium is a 29 FPS drop, from Medium to High is a 45 FPS drop, and from High to Ultra is an 8 FPS drop. This pattern shows that the GPU is starting to become more relevant at 1440p, as the resolution increase adds rendering load, but the CPU still limits the top-end settings.

At 4K, the averages are: 176 FPS on Low, 124 FPS on Medium, 88 FPS on High, and 84 FPS on Ultra. The Medium setting has a min of 106 FPS and a max of 143 FPS. The drop from Low to Medium is 52 FPS, which is the largest single-settings jump in the entire dataset, indicating a significant increase in GPU workload. From Medium to High, the drop is 36 FPS, and from High to Ultra, it is only 4 FPS. At 4K, the GPU is clearly the primary driver of frame rates, as the resolution demands more from the RTX 5090, but the High-to-Ultra plateau again points to a CPU limit.

CPU Role

The AMD Ryzen 5 5600F is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer. It has a base clock of 3.00 GHz and a boost clock of 4.00 GHz. The CPU's L3 cache is 32 MB shared, and it supports dual-channel DDR4 memory with a bandwidth of 51.2 GB/s. Its TDP is 65 W, and it is built on a 7 nm process.

In Pc Building Simulator, the CPU's role is paramount. The game is a simulation, meaning it constantly tracks and updates the state of computer components being assembled and tested. This requires significant single-thread performance. The 5600F's Passmark single-thread score of 2872 is decent, but not exceptional. Its multithread score is 19236, and its physics score is 1043.

The data shows that at 1080p, the frame rates are extremely high, ranging from 214 FPS on Ultra to 282 FPS on Low. These numbers indicate that the CPU is capable of driving the game at very high speeds, but the RTX 5090 is not being fully utilized. The fact that 1080p Ultra (214 FPS) is only 4 FPS lower than 1080p High (218 FPS) suggests that the game's simulation logic is hitting a hard ceiling around 214-218 FPS with this CPU, regardless of GPU load.

This is further evidenced by the 4K results. At 4K Low, the combo hits 176 FPS, which is lower than 1080p Ultra's 214 FPS. This shows that the GPU is now the bottleneck at 4K Low, as the resolution demands more rendering work. However, at 4K High (88 FPS) and 4K Ultra (84 FPS), the frame rates are nearly identical, which means the CPU is again the limit. The simulation's complexity scales with settings, and the 5600F's single-thread performance cannot keep up with the RTX 5090's ability to render frames quickly.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and refresh rate. At 1080p, the Ultra preset delivers 214 FPS on average. This is an excellent experience for any high-refresh-rate monitor, and the difference from High (218 FPS) is negligible. Therefore, for 1080p users, the Ultra preset is the recommended choice, as it provides the best visual quality without sacrificing meaningful performance.

At 1440p, the Ultra preset yields 160 FPS, which is still very high and suitable for most 144 Hz or 165 Hz displays. The High preset at 168 FPS offers a slight frame rate improvement, but the visual difference between High and Ultra in a simulation game is likely minimal. Given that the Ultra preset is only 8 FPS slower than High, running at Ultra is the better option for a more visually complete experience, as it still maintains a frame rate well above 144 FPS.

At 4K, the choice is more nuanced. The Ultra preset provides 84 FPS, which is playable but not ideal for high-refresh-rate gaming. The High preset at 88 FPS is nearly identical. The Medium preset, however, jumps to 124 FPS, which is a significant improvement. For a smoother experience at 4K, the Medium preset is the recommended setting, as it offers a 40 FPS advantage over Ultra while likely still looking good in a game that is not graphically intensive. The Low preset at 176 FPS is also viable for competitive play, but it would sacrifice visual fidelity.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals the limiting component at each stage. At 1080p Low, the combo achieves 282 FPS. Dropping to 1440p Low reduces this to 242 FPS, a 14% decrease. Moving to 4K Low yields 176 FPS, a 38% decrease from 1440p. These drops are moderate, indicating that even at Low settings, the GPU is being tasked more heavily as resolution increases, but the CPU is still contributing to the high baseline.

At Medium settings, the scaling is more pronounced. The 1080p Medium average is 248 FPS, 1440p Medium is 213 FPS, and 4K Medium is 124 FPS. The drop from 1080p to 1440p is 14%, and the drop from 1440p to 4K is 42%. This larger drop at 4K suggests that the GPU is now the primary limiting factor, as the resolution increases the pixel count and memory bandwidth demands.

At High settings, the pattern continues. 1080p High is 218 FPS, 1440p High is 168 FPS, and 4K High is 88 FPS. The drop from 1080p to 1440p is 23%, and from 1440p to 4K is 48%. This shows that at High settings, the GPU's rendering load is significant, but the 4K High result of 88 FPS is still higher than 4K Ultra's 84 FPS, which points back to the CPU limit at the highest settings.

At Ultra settings, the scaling is the most revealing. 1080p Ultra is 214 FPS, 1440p Ultra is 160 FPS, and 4K Ultra is 84 FPS. The drop from 1080p to 1440p is 25%, and from 1440p to 4K is 48%. However, the fact that 4K High (88 FPS) and 4K Ultra (84 FPS) are so close, while 1440p High (168 FPS) and 1440p Ultra (160 FPS) have a similar gap, suggests that the Ultra preset adds a simulation overhead that the CPU cannot handle at higher resolutions. The data indicates that the CPU is the limiting factor at Ultra settings across all resolutions, as the frame rates are capped around 84-214 FPS depending on resolution, while the GPU has headroom to render much faster if the CPU could feed it more frames.
