Pc Building Simulator

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

The AMD Ryzen AI Max+ 395 is a 16-core, 32-thread mobile processor built on the Zen 5 architecture (Strix Halo codename) at a 4 nm process node. Its base clock is 3.00 GHz with a boost clock of 5.10 GHz, and it carries a 55 W TDP. The chip features a substantial cache hierarchy: 80 KB L1 per core, 1 MB L2 per core, and 64 MB of shared L3 cache. Memory support includes LPDDR5X over a quad-channel bus, delivering 256.0 GB/s of bandwidth with ECC support enabled.

For Pc Building Simulator, a simulation title that relies heavily on consistent CPU throughput for game logic, shop management, and component interaction calculations, the Ryzen AI Max+ 395's high core count and strong single-thread performance are directly relevant. In Cinebench R23, the processor scores 35,314 in multicore and 2,044 in single-core. Geekbench results show 20,992 multicore and 2,464 single-core. The PassMark multithread score is 54,934, with a single-thread score of 4,147. These figures place the CPU in the 95th percentile among all tested processors, indicating top-tier performance headroom.

The benchmark data shows that this CPU is not the limiting factor at lower resolutions. At 1080p, the average FPS ranges from 161 (Ultra) to 337 (Low), which suggests the CPU can feed the GPU well beyond what most displays can show. Even at 4K Ultra, where the GPU typically becomes the bottleneck, the CPU's strong physics and integer math scores (PassMark integer math at 200,665 and floating-point math at 128,682) ensure that simulation logic does not introduce stutter or frame pacing issues.

Comparing to nearest rivals, the Ryzen AI Max+ 395's average benchmark score is 77,740. It sits 1.6% above the AMD Ryzen Threadripper PRO 9945WX (76,513) and the AMD EPYC Embedded 8224P (76,492), while being 1.7% below the Intel Core i9-14900K (79,097) and 2% above the AMD Ryzen 9 8945HX (76,212). The data suggests that in CPU-bound scenarios, the Ryzen AI Max+ 395 performs within a tight band of high-end desktop and workstation chips, despite its mobile classification. For a game like Pc Building Simulator, where frame rates at 1080p can exceed 300 FPS on Low settings, the CPU's capability is more than sufficient to avoid being a constraint.

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

The NVIDIA GeForce RTX 4080 is built on the Ada Lovelace architecture with the AD103 chip at a 5 nm process node from TSMC. It packs 45,900 million transistors on a 379 mm² die. The GPU operates at a base clock of 2205 MHz and a boost clock of 2505 MHz, with memory clocked at 1400 MHz (22.4 Gbps effective). Memory configuration includes 16 GB of GDDR6X on a 256-bit bus, yielding 716.8 GB/s of bandwidth. The shader configuration comprises 9,728 shading units, 304 TMUs, and 112 ROPs, along with 76 RT cores and 304 tensor cores. Pixel rate is 280.6 GPixel/s and texture rate is 761.5 GTexel/s, with FP32 performance at 48.74 TFLOPS.

For Pc Building Simulator, the GPU's role is less about raw rasterization of complex scenes and more about delivering smooth framerates across the various UI elements, 3D component previews, and the benchmark's rendering of assembled systems. The RTX 4080's 16 GB VRAM is ample for this title, which does not demand high texture memory at any resolution tested. The GPU's PassMark G3D score is 34,457, and its 3DMark Steel Nomad DX12 score is 6,567. These place the GPU in the 86th percentile of all GPUs.

The nearest rival comparison shows the RTX 4080's average benchmark score of 54,247 is virtually tied with the RTX 4080 SUPER at 54,209 (0.1% difference). It trails the AMD Radeon Pro W5700X by 1.1% (54,828) and the AMD Radeon RX 6750 GRE 12 GB by 2.6% (55,698), as well as the AMD Radeon 8060S by 2.7% (55,757). These small deltas suggest that in synthetic workloads, the RTX 4080 is competitive with a range of GPUs, but in this specific game, the measured FPS indicates the GPU handles the workload with significant headroom.

At 4K Ultra, the RTX 4080 delivers 53 FPS average, which is just below the 60 FPS threshold for smooth gameplay. At 4K High, it jumps to 56 FPS. The GPU's memory bandwidth of 716.8 GB/s is more than sufficient for the game's asset streaming, and the 16 GB VRAM ensures no texture swapping occurs even at 4K. The data shows that the GPU is the primary limiter only at 4K Ultra, where the frame rate drops to 53 FPS, whereas at 1440p and below, the system is likely CPU- or engine-limited at high settings.

# Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear scaling pattern across resolutions. At 1080p Low, the system achieves 337 FPS. Moving to 1440p Low drops this to 213 FPS, a 36.8% reduction. At 4K Low, the average is 111 FPS, another 47.9% drop from 1440p. This steep decline from 1080p to 1440p suggests that the GPU is becoming more involved, but the CPU still has headroom.

For Medium settings, the progression is 239 FPS at 1080p, 151 FPS at 1440p, and 79 FPS at 4K. The percentage drops are 36.8% from 1080p to 1440p, then 47.7% from 1440p to 4K. High settings show 169 FPS at 1080p, 106 FPS at 1440p (37.3% drop), and 56 FPS at 4K (47.2% drop). Ultra settings follow similarly: 161 FPS at 1080p, 101 FPS at 1440p (37.3% drop), and 53 FPS at 4K (47.5% drop).

The consistent pattern of roughly 37% reduction from 1080p to 1440p and 47-48% reduction from 1440p to 4K across all settings indicates that the rendering load scales predictably with pixel count. The fact that the drop between 1080p and 1440p is almost identical across Low and Ultra settings (36.8% vs 37.3%) suggests that at 1080p, even on Low, the system is not purely GPU-limited — otherwise, the percentage drop would be larger when going to 1440p on Low settings.

At 4K, the gap between Low (111 FPS) and Ultra (53 FPS) is 58 FPS, whereas at 1080p, the gap is 176 FPS (337 vs 161). This compression at higher resolutions indicates the GPU becomes the dominant constraint at 4K. The data supports the interpretation that at 1080p and 1440p, the CPU and GPU are reasonably balanced for this title, but at 4K, the RTX 4080 is the clear bottleneck, particularly on Ultra where it delivers only 53 FPS.

The minimum FPS values recorded for Medium settings across all resolutions (203 at 1080p, 128 at 1440p, 67 at 4K) show that even the lowest dips remain playable at 1080p and 1440p. At 4K Medium, the 67 FPS minimum is still above 60 FPS, suggesting that Medium settings at 4K provide a consistent experience without major frame drops.

# Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. At 1080p, all settings provide playable frame rates, but the distinction between High (169 FPS) and Ultra (161 FPS) is only 8 FPS, while Medium (239 FPS) offers a significant jump. Given that the game is a simulation where visual fidelity matters for component inspection, High settings at 1080p deliver a strong balance: 169 FPS average, which is well above 144 Hz refresh rates, with only a 4.7% performance cost compared to Ultra. Low settings at 337 FPS are excessive for most displays and sacrifice visual quality unnecessarily.

At 1440p, Medium (151 FPS) and High (106 FPS) both exceed 100 FPS, making either viable for high-refresh monitors. The 45 FPS difference between Medium and High is notable, but High still provides smooth gameplay. Ultra at 101 FPS is nearly identical to High (106 FPS), so the visual upgrade from High to Ultra costs only 5 FPS — in this case, Ultra is a reasonable choice if the display supports it. However, the 50 FPS gap between Medium and High (151 vs 106) suggests that High settings are where the GPU starts to work noticeably harder, and for a simulation game where UI elements dominate, Medium might be the sweet spot for consistent high refresh rates.

At 4K, the situation is more constrained. Ultra (53 FPS) and High (56 FPS) are both below 60 FPS, which can result in noticeable stutter on standard 60 Hz displays. Medium (79 FPS) is the best choice for 4K, providing a 41% improvement over High while maintaining 67 FPS minimums. Low (111 FPS) is also viable but sacrifices visual quality. For 4K gaming, Medium settings offer the best measured experience: 79 FPS average with a 67 FPS minimum, ensuring smooth gameplay. The data suggests that 4K Ultra is not recommended for this combination, as the 53 FPS average falls below the 60 FPS threshold.

For users with high-refresh 1080p or 1440p monitors, High settings at 1080p (169 FPS) or Medium at 1440p (151 FPS) provide the best balance of visual quality and frame rate. The measured rows indicate that pushing to Ultra at any resolution yields diminishing returns, with the largest performance cost occurring at 4K (53 vs 56 FPS for High, a 5.7% drop).

# Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

1920x1080:

• Low: 337 FPS average
• Medium: 239 FPS average (minimum 203, maximum 275)
• High: 169 FPS average
• Ultra: 161 FPS average

2560x1440:

• Low: 213 FPS average
• Medium: 151 FPS average (minimum 128, maximum 173)
• High: 106 FPS average
• Ultra: 101 FPS average

3840x2160:

• Low: 111 FPS average
• Medium: 79 FPS average (minimum 67, maximum 91)
• High: 56 FPS average
• Ultra: 53 FPS average

The data shows a consistent hierarchy across all resolutions: Low delivers the highest frame rates, followed by Medium, then High, with Ultra being the most demanding. The gap between Medium and High is substantial at every resolution: at 1080p, the difference is 70 FPS (239 vs 169); at 1440p, it is 45 FPS (151 vs 106); and at 4K, it is 23 FPS (79 vs 56). The gap between High and Ultra is much smaller: 8 FPS at 1080p (169 vs 161), 5 FPS at 1440p (106 vs 101), and 3 FPS at 4K (56 vs 53). This pattern suggests that the Ultra preset adds minimal visual benefit over High while incurring a small but consistent performance cost.

The minimum FPS values, available only for Medium settings, show that at 1080p the minimum is 203 FPS (85% of average), at 1440p it is 128 FPS (85% of average), and at 4K it is 67 FPS (85% of average). The consistency of this ratio across resolutions indicates that frame pacing is stable, with no unexpected stutters or spikes at any resolution.

# How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of AMD Ryzen AI Max+ 395 and NVIDIA GeForce RTX 4080 ranks 908th out of 3,002 tested combos in Pc Building Simulator. This places the combo in the top 30.2% of all tested configurations. Given that the dataset includes a wide range of CPUs and GPUs, this ranking reflects a strong but not elite position for this specific game.

The rank of 908 suggests that while the RTX 4080 is a high-end GPU (86th percentile) and the Ryzen AI Max+ 395 is a top-tier CPU (95th percentile), the combination does not reach the top tier of performance in this particular title. This is likely due to the game's simulation nature, where the GPU is not the sole determinant of frame rates — the CPU's role in handling game logic and component interactions is equally important.

Comparing to the nearest rival GPUs, the RTX 4080's average benchmark score is 54,247, nearly identical to the RTX 4080 SUPER at 54,209 (0.1% difference). If the combo were paired with the RTX 4080 SUPER, the ranking would likely shift only marginally. The AMD Radeon RX 6750 GRE 12 GB and AMD Radeon 8060S both score higher in synthetic benchmarks (55,698 and 55,757 respectively), but the measured FPS in this game could differ due to driver optimizations and game-specific rendering paths.

The CPU's nearest rivals — the Ryzen Threadripper PRO 9945WX and EPYC Embedded 8224P — score within 1.6% of the Ryzen AI Max+ 395. Swapping to one of these would likely produce negligible FPS changes in Pc Building Simulator, as the game is not heavily multithreaded. The Intel Core i9-14900K, which scores 1.7% higher on average, might edge out a slightly better rank, but the delta is small.

In context, a rank of 908 out of 3,002 means the combo outperforms roughly 69.8% of tested configurations. For a simulation game that is not graphically demanding, this position is expected — many combos with lower-end GPUs but high-end CPUs could achieve similar frame rates, as the game's engine may cap performance based on single-thread CPU speed rather than GPU throughput. The data indicates that this combo is well-suited for 1080p and 1440p high-refresh gameplay, and adequate for 4K at Medium settings, but it does not top the charts due to the game's modest GPU requirements.
