# GPU Role

The NVIDIA GeForce RTX 4090 is the dominant component in this pairing, and its specifications explain the measured frame rates. With a base clock of 2235 MHz and a boost clock of 2520 MHz, the GPU's Ada Lovelace architecture (5 nm process from TSMC) delivers 82.58 TFLOPS of FP32 performance. The 24 GB of GDDR6X memory on a 384-bit bus provides 1.01 TB/s of bandwidth, which is critical for Pc Building Simulator's texture-heavy environments.

The GPU's 16,384 shading units, 512 TMUs, and 176 ROPs process geometry and pixels efficiently. More importantly, the 128 RT cores and 512 tensor cores indicate that ray-traced or DLSS-enhanced workloads would be handled with ease, though the measured data does not specify whether these features were enabled. The pixel rate of 443.5 GPixel/s and texture rate of 1,290.2 GTexel/s explain why the GPU maintains high frame rates even at 4K.

At 4K Ultra, the combo achieves 79.5 FPS, which is respectable but not extreme. The drop from 4K High (85.3 FPS) to 4K Ultra (79.5 FPS) is only 6.8%, suggesting that Ultra settings add modest load. The 4K Low result of 171 FPS shows the GPU's raw capability when shader complexity is reduced. The RTX 4090's benchmark percentile of 91 places it among the top GPUs, and its average score of 66,473 reflects its compute muscle. Interestingly, its nearest rivals are professional cards (Tesla T4, Tesla P40), indicating that in synthetic tests, this consumer GPU competes with workstation hardware.

# Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. At 1920x1080, even Ultra settings deliver 247.8 FPS, which exceeds any current high-refresh display. The Low preset reaches 341.8 FPS, but the visual fidelity loss is unnecessary given the headroom. For 1080p, the data suggests High settings (257.5 FPS) provide the best balance, as the gap to Ultra (247.8) is only 3.9% but the quality difference may be noticeable.

At 2560x1440, High settings yield 164.5 FPS, comfortably above 144 Hz displays. The Medium preset (234 FPS) offers a massive uplift over High, but the visual reduction may not justify the 42.2% improvement for most users. Ultra at 1440p (157.7 FPS) still clears 144 Hz, making it a viable choice for those prioritizing image quality. The data shows that 1440p Ultra is only 4.1% slower than 1440p High, so the Ultra preset is recommended for this resolution.

At 3840x2160, the situation changes. High settings (85.3 FPS) are playable on 60 Hz displays, but Medium (122.9 FPS) provides a smoother experience. Ultra (79.5 FPS) dips below 80 FPS, which might cause judder on 120 Hz panels. The Low preset (171 FPS) is overkill for 4K. For 4K, Medium settings offer the best compromise: 44.1% faster than High while maintaining reasonable quality. Given that the GPU is end-of-life per production status, future-proofing with High settings at 4K is defensible, but the measured data points to Medium as the sweet spot.

# Measured FPS Breakdown

The measured FPS data reveals a clear hierarchy across resolutions and settings. At 1920x1080, the combo delivers 341.8 FPS on Low, 298.2 FPS on Medium, 257.5 FPS on High, and 247.8 FPS on Ultra. The step from Low to Medium is 43.6 FPS (12.8% drop), from Medium to High is 40.7 FPS (13.6% drop), and from High to Ultra is 9.7 FPS (3.8% drop). This pattern suggests diminishing returns as settings increase, with Ultra adding minimal load over High at 1080p.

Moving to 2560x1440, the numbers shift: Low hits 291 FPS, Medium 234 FPS, High 164.5 FPS, and Ultra 157.7 FPS. The drop from Low to Medium is 57 FPS (19.6%), larger than at 1080p, indicating the GPU is working harder. The drop from Medium to High is 69.5 FPS (29.7%), a significant jump. High to Ultra is only 6.8 FPS (4.1%), showing that Ultra adds little stress at 1440p.

At 3840x2160, performance scales down further: Low 171 FPS, Medium 122.9 FPS, High 85.3 FPS, and Ultra 79.5 FPS. The Low-to-Medium drop is 48.1 FPS (28.1%), Medium-to-High is 37.6 FPS (30.6%), and High-to-Ultra is 5.8 FPS (6.8%). The resolution scaling from 1080p to 4K shows a consistent pattern: at Ultra, FPS drops from 247.8 to 79.5, a 67.9% reduction, which aligns with the pixel count increase from 2.07 million to 8.29 million.

# How This Combo Ranks

The combo ranks 76th out of 1,769 tested combinations in Pc Building Simulator, placing it in the top 4.3% of all systems. This high ranking is driven by the RTX 4090's GPU compute power, which dominates the 3DMark Steel Nomad DX12 score of 9,223 and Passmark G3D score of 38,194. The CPU's contribution is secondary but not negligible, as the Ryzen 7 5700X's 83rd percentile ranking ensures no major bottleneck.

The rank of 76 out of 1,769 means there are 75 combos that outperform this one in this specific game. Given that the RTX 4090 is end-of-life and the CPU is mid-range, this ranking reflects the game's modest requirements—Pc Building Simulator is a simulation title that does not stress GPU geometry as heavily as AAA shooters. The combo's performance is more than sufficient for the game's mechanics, which involve building and managing PCs rather than fast-paced action.

# CPU Role

The AMD Ryzen 7 5700X is a Zen 3 (Vermeer) processor on the AM4 socket, built on TSMC's 7 nm process with 4,150 million transistors on a 74 mm² die. Its 8 cores and 16 threads run at a base clock of 3.40 GHz and boost to 4.60 GHz, with a 65 W TDP. The cache hierarchy includes 64 KB L1 per core, 512 KB L2 per core, and 32 MB shared L3. This configuration powers the CPU's 83rd percentile ranking.

In Pc Building Simulator, the CPU's role is to manage game logic, component interactions, and physics calculations. The Cinebench R23 multi-core score of 22,620 and single-core score of 3,193 indicate balanced performance. The 3DMark 16-thread score of 6,858 is nearly identical to the max-threads score of 6,850, showing that the CPU saturates all 16 threads efficiently. The Geekbench multi-core score of 9,720 and single-core score of 2,148 further confirm this.

The CPU's nearest rival, the Intel Core i9-11900KF, scores 26,196 on average, a 0.1% difference. This near-parity means the Ryzen 7 5700X is not a limiting factor in this combo. At 1080p Low, the FPS of 341.8 suggests the CPU can feed the GPU adequately, though the smaller FPS gains at 1080p (compared to 1440p) hint that the CPU starts to matter more as resolution drops. The CPU's 16 threads are sufficient for the game's simulation logic, and its 32 MB L3 cache reduces memory latency.

# Resolution Scaling

The FPS scaling from 1080p to 4K reveals the bottleneck characteristics. At Low settings, the FPS drops from 341.8 at 1080p to 291 at 1440p (14.9% decrease) and then to 171 at 4K (41.2% decrease from 1440p). The total drop from 1080p to 4K at Low is 50.0%, which is less than the 67.9% drop at Ultra. This discrepancy indicates that at Low settings, the CPU becomes a larger factor, limiting the GPU's ability to scale with resolution.

At Medium settings, the FPS goes from 298.2 at 1080p to 234 at 1440p (21.5% drop) and then to 122.9 at 4K (47.5% drop from 1440p). The total drop is 58.8%, closer to the pixel-count increase. At High settings, the FPS drops from 257.5 to 164.5 (36.1% drop) and then to 85.3 (48.1% drop), totaling 66.9%. At Ultra, the drops are 36.3% and 49.6%, totaling 67.9%.

The pattern shows that as settings increase, the GPU becomes the primary bottleneck, with FPS scaling nearly matching the pixel count. At Low settings, the CPU limits scaling—the 50% FPS drop at 4K is less than the 300% pixel increase, suggesting the CPU cannot push enough frames. For 1440p, the FPS drops from 1080p are moderate across all settings, indicating a balanced load. The 4K results, especially at High and Ultra, show the RTX 4090's limits in this game, while the 1080p Low result shows the CPU's ceiling.
