Pc Building Simulator

The Intel Core i5-11400F paired with the NVIDIA GeForce RTX 3080 delivers a wide spread of frame rates in Pc Building Simulator, ranging from a playable 55.4 FPS at 4K High to a near-effortless 299.1 FPS at 1080p Low. The data shows a classic resolution-scaling pattern where the performance gap between settings narrows as pixel count drops, indicating where the system transitions from GPU-bound to CPU-bound behavior.

Resolution Scaling

The measured FPS values reveal a pronounced shift in the system's bottleneck as resolution changes. At 3840x2160, the RTX 3080 is clearly the limiting component: the spread between Low and Ultra settings is a massive 57.6 FPS, with Low hitting 113.6 FPS and Ultra dropping to 56 FPS. This wide delta at 4K is typical of a scenario where the GPU's pixel throughput is the primary constraint, and the game's settings directly modulate that load.

Moving to 2560x1440, the picture changes. The Low setting jumps to 224.7 FPS, more than doubling the 4K Low result, while Ultra reaches 103.5 FPS. The gap between Low and Ultra here is 121.2 FPS, which is proportionally larger than at 4K, suggesting that the CPU is starting to exert more influence at the lower settings. At 1920x1080, the trend accelerates: Low hits 299.1 FPS, but Ultra still manages 168.7 FPS. The difference between Low and Ultra at 1080p is 130.4 FPS, nearly identical to the 1440p delta, but the absolute ceiling is much higher.

The critical observation is the frame rate growth from 4K to 1080p. At High settings, the FPS goes from 55.4 at 4K to 112.9 at 1440p to 175.7 at 1080p. This is a 3.2x increase from 4K to 1080p, which is less than the 4x pixel-count reduction, indicating that the CPU is beginning to cap performance at lower resolutions. The data suggests that at 1080p Low, the 299.1 FPS result is very close to the practical ceiling for this CPU-GPU combination in this simulation title.

Q: How does the GPU's clock speed relate to its benchmark performance?

A: The RTX 3080 has a base clock of 1440 MHz and boosts to 1710 MHz. Its PassMark G3D score is 25086, and its overall average benchmark score is 35787, which places it in the 80th percentile of all GPUs, indicating strong compute capabilities that translate well to this simulation's rendering workload.

GPU Role

The NVIDIA GeForce RTX 3080 is the dominant component in this pairing, and the measured FPS data confirms its importance. The GPU's 10 GB of GDDR6X memory, running at 19 Gbps effective on a 320-bit interface, provides 760.3 GB/s of bandwidth—a figure that proves adequate for 4K Ultra settings in Pc Building Simulator, where the average FPS is 56. The GPU's architecture, built on Samsung's 8 nm process with 28,300 million transistors, delivers 29.77 TFLOPS of FP32 compute, which is substantial for a simulation title that likely relies on particle effects and system visualization.

The clock behavior is also telling. With a base of 1440 MHz and a boost of 1710 MHz, the RTX 3080 maintains high utilization across all tested settings. At 4K Ultra, the system achieves 56 FPS, while at 4K Low it reaches 113.6 FPS—a doubling that shows the GPU's scaling with reduced shader complexity. The GPU's PassMark G3D score of 25086 and its 80th percentile ranking among all GPUs corroborate the in-game results: this is a high-end card that handles the game's rendering demands with headroom, except at the most demanding 4K Ultra preset.

The memory subsystem deserves attention. The 320-bit bus and 760.3 GB/s bandwidth are not maxed out in this game, as evidenced by the smooth performance at 4K. If the game were VRAM-hungry, we would expect to see larger gaps between High and Ultra at 4K, but the difference is only 0.6 FPS (55.4 vs 56). This suggests the game is more sensitive to raw compute and pixel fill rate than to memory capacity or bandwidth. The GPU's pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s are the likely drivers of the observed scaling.

How This Combo Ranks

In the benchmark database, this Intel Core i5-11400F + NVIDIA GeForce RTX 3080 combination ranks 582nd out of 1769 tested combos in Pc Building Simulator. This places it in the top third of all systems, which is a strong result given that the CPU is a mid-range part from 2021. The rank reflects the balance between the GPU's high compute capability and the CPU's moderate thread count.

The CPU's percentile ranking (75th among all CPUs) and the GPU's percentile ranking (80th among all GPUs) are closely aligned, which explains why the combo performs well without obvious mismatches. The data shows that this pairing is not holding either component back significantly: at 1080p High, the system hits 175.7 FPS, and at 4K High it drops to 55.4 FPS, a range that indicates the GPU is the primary driver at higher resolutions, while the CPU becomes relevant only at lower settings. The rank of 582 suggests that many higher-end combos (likely with more powerful CPUs) edge out this configuration in CPU-bound scenarios, but the RTX 3080 keeps it competitive across the board.

CPU Role

The Intel Core i5-11400F, with 6 cores and 12 threads, has a base clock of 2.60 GHz and a boost of 4.40 GHz. These specifications are modest by modern standards, but the data shows they are sufficient for Pc Building Simulator. The CPU's Cinebench R23 multi-core score of 14372 and single-core score of 2029 indicate balanced performance, which aligns with the game's need for both simulation logic and rendering thread management.

The CPU's role becomes evident in the measured FPS at lower resolutions. At 1080p Low, the system reaches 299.1 FPS, but this is likely near the CPU's limit. The 3DMark max-threads score of 5652 and PassMark multi-thread score of 16908 suggest that the 12 threads are fully utilized in this game's workload. The L3 cache of 12 MB shared across the cores is adequate for a simulation title that likely has moderate per-thread memory requirements.

The data shows a subtle CPU bottleneck at 1080p. Comparing 1080p Low (299.1 FPS) to 1440p Low (224.7 FPS), the FPS increase is only 33.1% while the pixel count decreases by 44%. This indicates that at 1080p, the CPU is unable to fully feed the GPU, capping performance below what the RTX 3080 could theoretically deliver. However, this is not a severe bottleneck—the system still produces extremely high frame rates that are well beyond typical display refresh rates.

Measured FPS Breakdown

The complete measured FPS dataset for this combo in Pc Building Simulator is as follows:

At 3840x2160, the average FPS scales with settings: Low delivers 113.6 FPS, Medium drops to 85.2 FPS, High reduces to 55.4 FPS, and Ultra bottoms out at 56 FPS. The near-identical High and Ultra results (55.4 vs 56) suggest the Ultra preset adds minimal additional GPU load over High, possibly due to a settings ceiling in the game engine.

At 2560x1440, the results are: Low at 224.7 FPS, Medium at 155.1 FPS, High at 112.9 FPS, and Ultra at 103.5 FPS. The gap between High and Ultra at 1440p is 9.4 FPS, which is larger than at 4K, indicating that the Ultra preset's extra effects become more impactful as resolution drops and GPU headroom increases.

At 1920x1080, the system produces its highest frame rates: Low at 299.1 FPS, Medium at 248.1 FPS, High at 175.7 FPS, and Ultra at 168.7 FPS. The difference between High and Ultra at 1080p is only 7 FPS, again showing the diminishing returns of the Ultra preset. The jump from Medium to High at 1080p is 72.4 FPS, which is the largest settings-based delta at any resolution, highlighting that High settings introduce a significant rendering cost.

These numbers paint a clear picture: the RTX 3080 is fully capable of 4K playable frame rates in this simulation title, and the i5-11400F provides enough CPU throughput to keep the GPU fed at lower resolutions, albeit with a ceiling around 300 FPS. The data confirms this is a well-balanced combo for Pc Building Simulator across all tested settings and resolutions.
