# CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 8400F brings a 6-core, 12-thread configuration built on the Zen 4 (Phoenix) architecture, fabricated on TSMC's 4 nm process. Its base clock of 4.20 GHz and boost clock of 4.70 GHz place it as a solid mid-range desktop part, with a 65 W TDP suggesting efficient operation. The CPU's cache hierarchy includes 64 KB L1 per core, 1 MB L2 per core, and a shared 16 MB L3 cache, which totals 25,000 million transistors on a 178 mm² die. Memory support is limited to DDR5 with dual-channel configuration, delivering 83.2 GB/s bandwidth.

Benchmark data shows this CPU performing at the 82nd percentile versus all CPUs, with an average benchmark score of 25,064. Its nearest rivals include the AMD Ryzen 7 2700X (score 25,057, delta 0%), the AMD Ryzen AI 5 PRO 340 (score 25,099, delta -0.1%), the AMD EPYC 9474F (score 25,103, delta -0.2%), and the AMD Ryzen 5 7500F (score 24,993, delta 0.3%). These razor-thin margins—all within 0.3%—indicate the 8400F sits in a tightly contested performance band where architectural differences translate to negligible real-world deltas.

In Pc Building Simulator, a game focused on assembling and managing hardware rather than rendering intense action, the CPU's multi-threaded capabilities matter for simulation logic. The 3DMark 16-thread score of 6,091 and max-thread score of 6,165 show strong scaling, while single-thread performance (951 in 3DMark single-thread) remains adequate for the game's menu-driven interactions. The Cinebench R23 multicore score of 20,851 and single-core score of 2,943 further characterize this CPU as balanced—not a workstation monster, but far from a bottleneck in a simulation title.

The boost clock of 4.70 GHz, combined with the 4 nm process, suggests the CPU can sustain high frequencies under light loads typical of Pc Building Simulator's UI-driven gameplay. However, the data reveals that at lower resolutions and settings, the CPU's role shifts—it must feed frames fast enough to keep the GPU busy, and the measured FPS at 1080p Low (206.3 avg) suggests the CPU is capable of driving very high frame rates when the GPU isn't the constraint.

# GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with the Navi 23 chip, fabricated on a 7 nm process from TSMC. It houses 11,060 million transistors on a 237 mm² die, with a base clock of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. Memory consists of 8 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s of bandwidth. The GPU features 1,792 shading units, 112 texture mapping units, and 64 ROPs, with 28 ray tracing cores. Its compute capabilities reach 8.928 TFLOPS FP32 and 17.86 TFLOPS FP16 (2:1 ratio), with pixel rate of 159.4 GPixel/s and texture rate of 279.0 GTexel/s.

The GPU's benchmark percentile stands at 69 versus all GPUs, with an average score of 25,235. Its nearest rivals include the AMD Radeon 890M (score 25,246, delta 0%), the AMD Radeon RX 580 2048SP (score 25,287, delta -0.2%), the AMD Radeon RX 6700M (score 25,180, delta 0.2%), and the NVIDIA GeForce RTX 3060 Ti (score 25,120, delta 0.5%). The sub-0.5% deltas again highlight a competitive cluster, though the RX 6600 trails the RTX 3060 Ti slightly.

In Pc Building Simulator, the GPU's role is visual output—rendering the workshop, computer cases, and component models. The 8 GB VRAM is sufficient for moderate resolutions, but the measured FPS at 4K Ultra (31.2 avg) suggests VRAM bandwidth or capacity becomes a limiting factor at extreme settings. The 128-bit bus and 224.0 GB/s bandwidth are modest, and the data shows a clear pattern: as resolution increases, the GPU's workload grows, and frame rates drop accordingly. At 1080p Low, the GPU delivers 206.3 FPS, but at 4K Ultra, it falls to 31.2 FPS—a dramatic reduction that points to the GPU as the primary bottleneck at high resolutions and settings.

The GPU's 2491 MHz boost clock provides decent headroom for simulation scenes, but the 14 Gbps effective memory speed and 8 GB capacity constrain performance in memory-heavy scenarios. The data indicates this GPU is best suited for 1080p and 1440p gaming, with 4K requiring significant settings compromises.

# How This Combo Ranks

This combination of AMD Ryzen 5 8400F and AMD Radeon RX 6600 ranks 1,411 out of 1,769 tested combos in Pc Building Simulator. This places it in the lower 20% of all combinations tested, which is notable given the individual components' mid-range positioning. The CPU's 82nd percentile and GPU's 69th percentile suggest each part is respectable on its own, yet the combined system lands in a low rank.

The discrepancy between component percentiles and combo rank implies that Pc Building Simulator's performance profile favors either stronger GPUs for high-resolution rendering or stronger CPUs for simulation overhead. The 8400F's 6 cores and 12 threads are sufficient for most tasks, but the RX 6600's modest memory bandwidth and VRAM capacity may limit performance in a game that simulates hardware configurations—potentially taxing GPU memory with complex scene rendering.

Compared to other combos, this pairing sits in the lower quartile, meaning 358 combos perform worse. This ranking suggests that while the system is playable, it does not excel in this specific title. The data indicates that users seeking better performance might pair a higher-tier GPU with this CPU, or alternatively, a stronger CPU with this GPU, depending on whether resolution or simulation speed is prioritized.

# Measured FPS Breakdown

The measured FPS data provides a comprehensive picture across four resolutions and four settings levels. At 1920x1080, the system delivers 206.3 FPS on Low, 147 FPS on Medium, 105.2 FPS on High, and 100.5 FPS on Ultra. These figures show excellent 1080p performance, with even Ultra settings comfortably above 100 FPS.

Moving to 2560x1440, the numbers drop: 132.4 FPS on Low, 89.6 FPS on Medium, 65.2 FPS on High, and 62.9 FPS on Ultra. The 1440p results remain playable, with Low settings exceeding 120 FPS and Ultra still above 60 FPS.

At 3840x2160, performance becomes more constrained: 69.4 FPS on Low, 49.2 FPS on Medium, 33.2 FPS on High, and 31.2 FPS on Ultra. The 4K results show a clear threshold—only Low settings achieve a smooth 60+ FPS experience, while Medium dips below 50 FPS, and High/Ultra fall into the low 30s.

These numbers reveal a consistent pattern: the system scales well from Low to Ultra at 1080p (a 51.2% drop from 206.3 to 100.5 FPS), but the drop becomes more severe at higher resolutions. At 1440p, the drop from Low to Ultra is 52.5% (from 132.4 to 62.9 FPS), while at 4K, it's 55.0% (from 69.4 to 31.2 FPS). This trend suggests the GPU's limitations become increasingly dominant as pixel count rises.

# Resolution Scaling

The FPS drop from 1080p to 4K is steep and tells a clear story about the limiting component. At Low settings, 1080p yields 206.3 FPS, while 4K yields 69.4 FPS—a 66.4% reduction. At Medium, the drop is from 147 to 49.2 FPS, a 66.5% reduction. High settings fall from 105.2 to 33.2 FPS (68.4% reduction), and Ultra from 100.5 to 31.2 FPS (69.0% reduction).

These near-consistent percentage drops across all settings indicate that resolution scaling is the dominant factor, not settings complexity. The GPU's 8 GB VRAM and 224.0 GB/s bandwidth are likely saturated at 4K, causing the frame rate to collapse regardless of detail level. The fact that Low settings at 4K (69.4 FPS) perform worse than Ultra at 1080p (100.5 FPS) underscores this GPU-bound scenario.

The data implies the CPU is not the bottleneck at higher resolutions—the 8400F's single-thread and multi-thread scores are sufficient to drive the simulation logic even as GPU load increases. This is evident because the FPS drop from 1080p to 1440p is roughly proportional (e.g., Low drops from 206.3 to 132.4, a 35.8% reduction), which aligns with pixel count scaling rather than CPU limitations.

# Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on target resolution and desired frame rate. At 1080p, all settings are viable, with Ultra delivering 100.5 FPS—a smooth experience for a simulation game. The data suggests Ultra at 1080p is the best balance, as the drop from High (105.2) to Ultra (100.5) is minimal, only 4.5%.

At 1440p, Ultra (62.9 FPS) remains playable, but High (65.2 FPS) offers marginal improvement. Medium (89.6 FPS) provides a substantial boost while maintaining visual quality. For users prioritizing frame rate stability, Medium at 1440p is recommended, as it sits well above 60 FPS with only a 13.6% penalty versus Low (132.4 FPS).

At 4K, only Low (69.4 FPS) achieves a comfortable frame rate. Medium (49.2 FPS) dips below 50, and High/Ultra fall into the low 30s, which is likely too choppy for a simulation that requires menu navigation and precise component placement. The recommendation is to use Low at 4K, or if visual fidelity is paramount, accept the 33.2 FPS of High but note the significant compromise.

For the best overall experience, the data supports 1080p Ultra or 1440p Medium as the sweet spots—both deliver above 60 FPS with reasonable visual quality. The 4K Ultra option (31.2 FPS) is only for users who prioritize resolution over smoothness.
