Pc Building Simulator

The AMD Ryzen 5 7400F and Radeon RX 6600 pairing delivers a playable but not lavish experience in Pc Building Simulator, with performance scaling that clearly exposes the GPU as the primary constraint as resolution climbs. The measured data shows a steep and consistent drop-off from 1080p to 4K across all settings, a pattern that defines this combo’s capabilities in a simulation title that is more about system logic than graphical spectacle.

Resolution Scaling

The frame rate curve from 1080p to 4K is instructive. At 1920x1080 with Low settings, the combo produces 206 FPS, which is an exceptionally high ceiling that suggests the CPU and GPU are both working well within their limits. Moving to 2560x1440 at Low drops the average to 130 FPS, a 37% reduction that is typical of a GPU-bound scenario where pixel count begins to matter. At 3840x2160 with Low settings, the average falls to 68 FPS, which is roughly half of the 1440p result and just a third of the 1080p figure. This linear degradation indicates that the RX 6600’s rendering pipeline is saturated by the increasing pixel workload, while the Ryzen 5 7400F remains largely idle in the background.

The scaling pattern holds for higher settings as well. At High settings, the combo delivers 103 FPS at 1080p, 65 FPS at 1440p, and 34 FPS at 4K. The drop from 1080p to 1440p is 37%, and from 1440p to 4K it is 48%, showing that the cost of 4K resolution is disproportionately higher than the step from Full HD to QHD. Ultra settings tell a similar story: 98 FPS at 1080p, 62 FPS at 1440p, and 32 FPS at 4K. The delta between 1080p and 4K at Ultra is 67%, which is a massive performance hit that no amount of CPU headroom can offset.

What this data reveals is that the limiting component is unequivocally the GPU. The CPU’s role in this title is to manage the simulation logic, but the rendering bottleneck dominates the frame rate trajectory. The fact that Low settings at 4K (68 FPS) nearly match High settings at 1440p (65 FPS) underscores that the GPU’s fill rate and memory bandwidth are the deciding factors, not the processor’s compute throughput. For users targeting 4K, the data suggests that even Low settings will struggle to maintain a smooth 60 FPS, while 1080p and 1440p offer much more headroom for visual fidelity.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with a Navi 23 chip, a 7 nm process, and a transistor count of 11,060 million. Its memory configuration is 8 GB of GDDR6 on a 128-bit bus, yielding a bandwidth of 224.0 GB/s. The clock speeds are notable: a base of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. These numbers directly influence the measured FPS in Pc Building Simulator, particularly at higher resolutions where memory bandwidth becomes a critical resource.

At 1080p, the GPU’s 8 GB frame buffer is more than sufficient, and the 224.0 GB/s bandwidth allows the card to push 206 FPS at Low settings without breaking a sweat. However, at 4K, the demands on memory bandwidth increase substantially. The 128-bit bus is a limiting factor here, and the data shows it: 4K Medium produces 48 FPS, which is a 67% drop from the 1080p Medium result of 146 FPS. The GPU’s 1792 shading units and 64 ROPs are also stressed at 4K, as the pixel rate of 159.4 GPixel/s is simply not enough to sustain high frame rates at that resolution.

The GPU’s VRAM capacity is another point of analysis. With 8 GB of GDDR6, the card is adequate for 1080p and 1440p gaming, but at 4K Ultra, the data shows 32 FPS, which suggests that memory capacity and bandwidth are both stretched thin. The lack of min FPS data for most entries (only Medium settings have min/max values) indicates that the benchmark suite may not have captured frame-time spikes, but the average figures are consistent with a GPU that is operating near its ceiling. The RX 6600’s percentile ranking of 63 among all GPUs places it in the mid-range tier, and its performance in this title aligns with that positioning—capable at lower resolutions, but not a 4K powerhouse.

How This Combo Ranks

In the grand scheme of tested combinations, this pairing of the Ryzen 5 7400F and RX 6600 ranks 2327 out of 3002 combos in Pc Building Simulator. This places it in the lower half of the database, which is a telling statistic for a game that is more CPU-dependent than most. The rank of 2327 out of 3002 means that roughly 78% of tested combos outperform it in this specific title. That may seem harsh, but the data suggests that the RX 6600 is holding back the otherwise capable Ryzen 5 7400F.

To contextualize the CPU’s potential, the Ryzen 5 7400F has an average benchmark score of 32750, which is nearly identical to its nearest rivals: the Intel Core i5-14600T scores 32707 (a 0.1% delta), the Intel Core Ultra 7 155H scores 32697 (0.2% delta), and the AMD Ryzen 7 PRO 6850H scores 32812 (-0.2% delta). This shows that the CPU is competitive with mid-range and even some higher-tier processors, yet the combo rank suffers because the GPU’s 63rd percentile standing drags the overall result down. The GPU’s nearest rivals include the NVIDIA Quadro K6000 (19030, 0% delta), the GeForce RTX 4050 Mobile (19049, -0.1% delta), and the Tesla K20m (19089, -0.3% delta), which are all older or mobile parts, further emphasizing that the RX 6600 is a modest performer in 2025.

The discrepancy between the CPU’s 83rd percentile ranking and the GPU’s 63rd percentile ranking is the core issue. The combo’s rank of 2327 out of 3002 is not a reflection of a weak CPU, but rather a GPU that cannot fully leverage the processor’s strengths. In a simulation game like Pc Building Simulator, where CPU logic is paramount, this pairing leaves performance on the table. Users who prioritize this title would be better served by a stronger GPU, but the data shows that the current configuration is still functional, just not optimal.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings. At 1920x1080, the combo starts strong: Low delivers 206 FPS, Medium delivers 146 FPS (with a min of 124 and max of 168), High delivers 103 FPS, and Ultra delivers 98 FPS. The gap between Low and Ultra is 108 FPS, a 52% reduction, but even the lowest figure remains well above playable thresholds. The Medium setting’s min FPS of 124 is particularly reassuring, indicating that frame pacing is stable even during complex simulation moments.

At 2560x1440, the performance drops are more pronounced. Low still manages 130 FPS, which is excellent for QHD, but Medium falls to 92 FPS (min 78, max 106), High drops to 65 FPS, and Ultra bottoms out at 62 FPS. The transition from 1080p to 1440p costs roughly 35-40% of performance across all settings, which is a significant but expected penalty. The Medium setting’s min FPS of 78 is still playable, but the High and Ultra results are approaching the edge of what most users would consider smooth.

At 3840x2160, the combo struggles. Low delivers 68 FPS, which is the only setting that approaches a playable threshold, but Medium drops to 48 FPS (min 41, max 55), High falls to 34 FPS, and Ultra limps to 32 FPS. The 4K results are consistently below 60 FPS, and the Medium setting’s min FPS of 41 indicates that significant frame drops can occur during intensive scenes. For a game that is not graphically demanding, these numbers are surprisingly low, reinforcing the notion that the RX 6600’s 128-bit memory bus and 8 GB VRAM are inadequate for 4K rendering in this title.

The trend across all resolutions is clear: Low settings offer the best headroom, Medium is a compromise, and High/Ultra are only viable at 1080p or occasionally 1440p. The data also shows that the min FPS figures, when available, are within 15% of the average, suggesting that frame time consistency is decent, but the overall averages are too low at 4K to recommend that resolution with this hardware.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Raphael, and manufactured on a 5 nm process by TSMC. It has a base clock of 3.70 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. In Pc Building Simulator, which is a simulation game that relies heavily on CPU logic for component interactions and system boot sequences, these specifications are more than adequate.

The CPU’s benchmark scores reinforce this. In Cinebench R23, it scores 21765 in multi-core and 3072 in single-core, while in PassMark’s multithread test it scores 25645. These numbers indicate that the 7400F has substantial computational headroom, and the data confirms that the CPU is not the bottleneck in this pairing. At 1080p Low, the combo achieves 206 FPS, which is likely near the engine’s limit, and the CPU’s single-thread performance of 3072 in R23 ensures that the simulation logic runs without stutter.

The CPU’s memory support for DDR5 with a dual-channel bus and 83.2 GB/s bandwidth is another asset, as simulation games often benefit from fast memory access. The 32 MB of L3 cache is also useful for keeping frequently accessed data close to the cores. However, the data shows that the CPU’s capabilities are underutilized at higher resolutions. At 4K Ultra, the combo only manages 32 FPS, and the CPU is likely idling while the GPU struggles. This is a classic case of imbalance: the Ryzen 5 7400F ranks in the 83rd percentile among all CPUs, but the GPU’s 63rd percentile ranking caps the overall system performance.

The nearest rival CPUs, such as the Intel Core i5-14600T and AMD Ryzen 7 PRO 6850H, have similar average scores, but the combo’s rank of 2327 out of 3002 shows that the GPU is the limiting factor. If the CPU were paired with a more powerful GPU, the rank would likely improve significantly, but the current data is clear: the 7400F is a strong processor that is being held back by the RX 6600 in this title.
