# Pc Building Simulator with AMD Ryzen 5 4600G + NVIDIA GeForce RTX 4080

Pc Building Simulator, a simulation title released on 2019-01-28, presents an unusual combination of components: a mid-range 2020-era CPU paired with a flagship-class 2022 GPU. The measured FPS data reveals a system that scales dramatically with resolution and settings, offering a clear window into which component dominates the workload at each configuration. The AMD Ryzen 5 4600G (6 cores, 12 threads, base 3.70 GHz, boost 4.20 GHz, Zen 2 architecture) sits at the 71st percentile of all CPUs, while the NVIDIA GeForce RTX 4080 (16 GB GDDR6X, Ada Lovelace architecture, 9728 shading units) ranks in the 86th percentile of all GPUs. This pairing creates a benchmark profile that shifts from CPU-limited at 1080p to GPU-limited at 4K, with the data showing exactly where that transition occurs.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and tells a clear story about the limiting component. At Low settings, the average FPS falls from 267 at 1920x1080 to 229 at 2560x1440 (a 14% reduction) and then to 155 at 3840x2160 (a 42% reduction from 1440p). This pattern indicates that at 1080p Low, the system is heavily CPU-bound—the Ryzen 5 4600G's single-thread performance (726 in 3dmark_single_thread, 1919 in cinebench_r23_singlecore) becomes the bottleneck, preventing the RTX 4080 from stretching its legs.

At High settings, the scaling is even more pronounced. The average FPS drops from 206 at 1080p to 148 at 1440p (a 28% reduction) and then to 78 at 4K (a 47% reduction from 1440p). The 4K High result of 78 FPS is significantly below the 1440p High result, suggesting that at this resolution, the RTX 4080's raw compute (48.74 TFLOPS FP32) is being taxed heavily by the simulation's rendering workload. The gap between 1080p and 1440p at High (58 FPS difference) is larger than the gap at Low (38 FPS difference), indicating that as settings increase, the GPU starts to become more relevant even at lower resolutions.

Ultra settings show the most dramatic scaling: 203 FPS at 1080p, 141 FPS at 1440p, and 74 FPS at 4K. The 4K Ultra result is the lowest of all measured configurations, and the drop from 1440p to 4K (67 FPS) is the largest single-step reduction in the entire dataset. This suggests that at Ultra settings and 4K resolution, the RTX 4080 is working at its limits, while the CPU has more headroom than at lower resolutions. The data implies that Pc Building Simulator at 4K Ultra is a GPU-bound scenario, whereas at 1080p Low, the Ryzen 5 4600G's 6 cores and 12 threads are the primary constraint.

CPU Role

The AMD Ryzen 5 4600G's role in this system is best understood through its benchmark profile and how it interacts with the RTX 4080. With 6 cores and 12 threads based on Zen 2 architecture (Renoir codename, 7 nm process, 9,800 million transistors), this CPU was designed for mainstream desktop use, not as a companion to a flagship GPU. Its 3dmark scores show a clear scaling pattern: 1430 with 2 threads, 2732 with 4 threads, 4138 with 8 threads, and 4889 with max threads. The jump from 8 to max threads is small (751 points), indicating that the CPU's multithreading scaling plateaus quickly—a trait that matters in a simulation game that may not use all 12 threads effectively.

The Cinebench results reinforce this picture: R15 multicore 1370, R20 multicore 5709, R23 multicore 13593. The single-core scores (R15 193, R20 805, R23 1919) are modest by modern standards, which explains why the system struggles to exceed 267 FPS at 1080p Low. The PassMark single-thread score of 2653 and multithread score of 15992 further confirm that this CPU is a capable but not exceptional performer, ranking in the 71st percentile of all CPUs. Its nearest rivals include the AMD Ryzen 3 PRO 5355GE (avgScore 17482, deltaPct 0.1) and the Intel Core i3-14100T (avgScore 17648, deltaPct -0.8), showing that it sits in a competitive but not leading position.

The CPU's 8 MB shared L3 cache and 51.2 GB/s memory bandwidth (DDR4 dual-channel) are adequate for gaming, but the data suggests that Pc Building Simulator's simulation logic is not heavily multithreaded. The measured FPS at 1080p Low (267 FPS) versus 1080p Ultra (203 FPS) shows only a 24% difference, indicating that even at Low settings, the CPU cannot push frame rates much higher. This is a classic CPU-bound scenario: the RTX 4080 is capable of far more, but the Ryzen 5 4600G's single-thread performance becomes the ceiling.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this pairing, and the data shows it being progressively more utilized as resolution and settings increase. With 16 GB of GDDR6X memory on a 256-bit bus providing 716.8 GB/s bandwidth, the GPU has ample resources for Pc Building Simulator's needs. Its clocks (base 2205 MHz, boost 2505 MHz) and 9728 shading units deliver 48.74 TFLOPS FP32 performance, placing it in the 86th percentile of all GPUs. Its nearest rival, the RTX 4080 SUPER, scores 54209 with a deltaPct of 0.1, while the AMD Radeon RX 6750 GRE 12 GB scores 55698 with a deltaPct of -2.6.

The GPU's benchmark scores reflect its top-tier status: PassMark G3D 34457, Geekbench OpenCL 214739, Geekbench Vulkan 263779. The 3dmark Steel Nomad DX12 score of 6567 indicates strong DirectX 12 performance, which is relevant for Pc Building Simulator's modern rendering pipeline. The 16 GB VRAM is more than sufficient for this game, even at 4K Ultra, where the measured 74 FPS average suggests the GPU is the primary constraint rather than memory capacity.

The measured FPS data shows the RTX 4080's strength at lower resolutions being masked by the CPU. At 1080p Low (267 FPS) and 1080p Medium (235 FPS), the GPU is likely idling, waiting for the CPU to feed it frames. However, at 4K Ultra (74 FPS), the GPU is fully engaged, and the 16 GB GDDR6X memory and 716.8 GB/s bandwidth are being put to use. The transition from CPU-bound to GPU-bound is visible in the scaling: at 1080p, the difference between Low and Ultra is 64 FPS (267 to 203), while at 4K, the difference is 81 FPS (155 to 74). This wider spread at 4K indicates that the GPU is the limiting factor at higher resolutions, with its performance scaling more directly with settings.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce 267 FPS average, Medium yields 235 FPS (with min 199, max 270), High reaches 206 FPS, and Ultra achieves 203 FPS. The narrow gap between High (206) and Ultra (203) is notable—only 3 FPS separates them, suggesting that the CPU is the bottleneck at these settings, not the GPU. The Medium preset's min FPS of 199 and max of 270 show a wide variance, indicating frame pacing variability that could be caused by CPU load spikes during simulation events.

At 2560x1440, the FPS drops are more pronounced. Low settings average 229 FPS, Medium averages 201 FPS (with min 171, max 231), High averages 148 FPS, and Ultra averages 141 FPS. The gap between High and Ultra narrows further to 7 FPS, while the gap between Low and Medium is 28 FPS. The Medium min FPS of 171 is significantly lower than the average of 201, suggesting occasional stutters that could be attributed to the CPU's 8 MB L3 cache being insufficient for certain simulation scenarios. The 1440p results show the system is still partially CPU-bound at lower settings, but the GPU begins to play a larger role at High and Ultra.

At 3840x2160, the data reveals a clear GPU-bound scenario. Low settings average 155 FPS, Medium averages 110 FPS (with min 93, max 126), High averages 78 FPS, and Ultra averages 74 FPS. The gap between Low and Medium is 45 FPS, and between Medium and High is 32 FPS, showing that the GPU's performance scales more linearly with settings at 4K. The High and Ultra results (78 and 74 FPS) are close, suggesting diminishing returns from the highest preset. The Medium min FPS of 93 is the lowest recorded in the entire dataset, indicating that even at Medium settings, the system can experience significant frame drops at 4K.

A: At 1080p, High averages 206 FPS and Ultra 203 FPS—a 3 FPS difference. At 1440p, High averages 148 FPS and Ultra 141 FPS—a 7 FPS difference. This suggests the CPU is the bottleneck at these resolutions, as the GPU has headroom that the Ryzen 5 4600G cannot utilize.

Q: Does the Medium preset show any performance issues?

A: The Medium preset at 4K shows an average of 110 FPS with a min of 93 FPS, which is the lowest minimum in the dataset. At 1440p Medium, the min is 171 FPS, and at 1080p Medium, the min is 199 FPS. These minimums indicate occasional frame drops that could be noticeable during simulation-heavy moments.

Settings Recommendations

The measured data suggests a clear hierarchy for optimal performance based on resolution. At 1920x1080, the High preset (206 FPS) offers a marginal improvement over Ultra (203 FPS) in terms of frame rate, but the near-identical scores imply that Ultra may be worth the extra visual fidelity given the negligible performance cost. However, the 267 FPS at Low shows that competitive players or those seeking maximum smoothness could drop to Low, though the gain over High is only 23%.

At 2560x1440, the High preset (148 FPS) provides a strong balance, with Ultra (141 FPS) trailing by only 7 FPS. The Medium preset (201 FPS) offers a significant 36% improvement over High, but the min FPS of 171 suggests potential stuttering. For most users, High at 1440p appears to be the sweet spot, delivering smooth gameplay without compromising visual quality.

At 3840x2160, the data tells a different story. Ultra (74 FPS) and High (78 FPS) are nearly identical, with Medium (110 FPS) offering a substantial 41% boost over High. The Medium preset's min FPS of 93, while lower than the average, still remains above 60 FPS, making it the recommended choice for 4K gaming. Low (155 FPS) is also viable, but the visual trade-off may not be worth the frame rate gain. The High preset at 4K (78 FPS) is borderline for 60 Hz displays, while Ultra (74 FPS) offers no meaningful advantage over High.

How This Combo Ranks

This combination of AMD Ryzen 5 4600G and NVIDIA GeForce RTX 4080 ranks 705th out of 3723 tested combos in Pc Building Simulator, placing it in the top 19% of all configurations. The ranking reflects the system's ability to deliver high frame rates across most resolutions, despite the CPU being a bottleneck at lower settings. The combo's percentile ranking of 705/3723 suggests that while the RTX 4080 contributes significantly, the Ryzen 5 4600G holds the system back from the top tier.

The CPU's 71st percentile ranking among all CPUs and the GPU's 86th percentile ranking among all GPUs create an imbalance that is visible in the data. The RTX 4080's nearest rivals (RTX 4080 SUPER at deltaPct 0.1, AMD Radeon Pro W5700X at deltaPct -1.1) all outperform the CPU's nearest rivals (AMD Ryzen 3 PRO 5355GE at deltaPct 0.1, Intel Core i3-14100T at deltaPct -0.8) in their respective benchmark hierarchies. This suggests that in Pc Building Simulator, the GPU has more headroom to contribute than the CPU, which aligns with the observed scaling from 1080p to 4K.

The rank of 705 out of 3723 indicates that this combo outperforms a majority of tested configurations, likely due to the RTX 4080's raw power dominating at higher resolutions. However, the data implies that upgrading the CPU to a more powerful model would yield significant gains at 1080p and 1440p, where the Ryzen 5 4600G's single-thread performance (726 3dmark single-thread score) becomes the limiting factor. The system's overall ranking suggests it is a capable but not top-tier combination, with the GPU carrying most of the weight in this pairing.
