Pc Building Simulator

Pc Building Simulator is a simulation title that rarely stresses high-end hardware, and the Intel Core i5-12600KF paired with the NVIDIA GeForce RTX 4080 SUPER delivers frame rates that range from playable at 4K Ultra to exceptionally high at 1080p. The data shows a combo that is heavily GPU-bound at higher resolutions but becomes increasingly CPU-limited as resolution drops, a dynamic that shapes the entire experience. With a combo rank of 101 out of 1769 tested configurations, this pairing sits in the top tier of results, though its performance profile reveals more nuance than a simple ranking suggests.

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

The RTX 4080 SUPER is built on the Ada Lovelace architecture and manufactured on a 5 nm process by TSMC. It carries 16 GB of GDDR6X memory across a 256-bit bus, providing 736.3 GB/s of bandwidth. The GPU's base clock is 2295 MHz, boosting to 2550 MHz, with memory running at 1438 MHz (23 Gbps effective). These specifications are substantial, but in Pc Building Simulator, the GPU's role is primarily to push pixels at high resolutions and settings, which the measured frames per second data confirms.

At 4K Ultra, the combo averages 72.1 FPS, which is the lowest result in the dataset. The GPU is clearly the limiting factor here, as the 16 GB VRAM buffer and 736.3 GB/s bandwidth are being taxed by the game's highest visual demands. However, the GPU's capability is evident when settings are reduced: at 4K Low, the average FPS jumps to 152.2, a 111% increase over Ultra. This dramatic scaling indicates that the RTX 4080 SUPER has ample headroom when the game's shader and texture loads are lightened.

The CPU, an Intel Core i5-12600KF with 10 cores and 16 threads, has a base clock of 3.70 GHz and a boost clock of 4.90 GHz. Its 20 MB of shared L3 cache and dual-channel DDR4/DDR5 memory support are sufficient for a simulation game that does not heavily multithread. The CPU's 3DMark max threads score of 7952 and Cinebench R23 multicore score of 23444 indicate strong throughput, but in this game, the CPU's single-thread performance (Cinebench R23 single-core: 3309) is more relevant for maintaining frame pacing. The data suggests the CPU is not a bottleneck at 4K, where the GPU dominates the workload, but it becomes more influential at lower resolutions.

FAQ — 4-6 Q&A pairs answerable from FACT PACK data

Q: What is the average FPS at 1440p with High settings?

A: The combo delivers an average of 147.9 FPS at 2560x1440 with High settings, which is nearly double the 4K High result of 78.8 FPS. This indicates that 1440p is a sweet spot where the GPU is still heavily utilized but not overwhelmed.

Q: How much faster is the RTX 4080 SUPER than its nearest rival?

A: The GPU's average benchmark score is 53610, which is 0.2% ahead of the AMD Radeon RX 6900 XT (53489) and 0.4% ahead of the AMD Radeon Pro W6600M (53414). The margin over the NVIDIA GeForce RTX 5070 Ti is larger at 2.9%, with the 5070 Ti scoring 52086.

Q: Does the CPU bottleneck the GPU at 1080p?

A: Yes, the data indicates CPU limitation at 1080p. At 1080p Low, the average FPS is 392.7, but at 1080p Ultra, it drops to 224.6. The gap between settings narrows at higher resolutions, suggesting the CPU's single-thread performance caps frame rates when the GPU is not the constraint.

Q: What is the best 4K setting for smooth gameplay?

A: Medium settings at 4K produce an average of 108.6 FPS, which comfortably exceeds the 60 FPS threshold. High settings at 4K deliver 78.8 FPS, while Ultra drops to 72.1 FPS. For a consistent experience, Medium or High are the recommended choices.

Q: How does the CPU compare to the Intel Core i9-10900K?

A: The i5-12600KF has an average benchmark score of 27827, which is effectively identical to the i9-10900K's 27829, showing a deltaPct of 0. The i5-12600K is 0.1% faster with a score of 27851, while the Core Ultra 5 125H is 0.2% slower at 27872.

Q: What is the frame rate difference between 1080p and 4K at Ultra settings?

A: At 1080p Ultra, the average FPS is 224.6, while at 4K Ultra, it falls to 72.1. This represents a 67.9% reduction in frame rate, highlighting that the GPU is the primary scaling factor at higher resolutions.

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

The measured FPS data across resolutions reveals a clear pattern of GPU-bound scaling. At 1080p Low, the combo achieves 392.7 FPS, which drops to 297.4 FPS at 1440p Low (a 24.3% decrease) and further to 152.2 FPS at 4K Low (a 61.2% decrease from 1080p). This steep decline at 4K Low indicates that even with minimal settings, the RTX 4080 SUPER's pixel throughput is the limiting factor at that resolution.

At Ultra settings, the scaling is less severe but still significant. The drop from 1080p Ultra (224.6 FPS) to 1440p Ultra (142.2 FPS) is 36.7%, and from 1440p Ultra to 4K Ultra (72.1 FPS) is 49.3%. The fact that the percentage drop from 1440p to 4K is larger than from 1080p to 1440p suggests that the GPU's memory bandwidth and shader resources are being stretched progressively harder as pixel count increases. The 736.3 GB/s bandwidth becomes a more critical constraint at 4K, where the 16 GB frame buffer is fully utilized.

The data also reveals the CPU's role at lower resolutions. At 1080p Low, the 392.7 FPS result is likely near the CPU's maximum frame delivery capability, given the i5-12600KF's single-thread score of 1016 in 3DMark. When settings are raised to Ultra at 1080p, the FPS drops to 224.6, indicating the GPU is now the bottleneck even at this resolution. This transition point—where the GPU becomes the limiting factor—occurs between Low and Medium settings at 1080p, as Medium produces 332.7 FPS, still high but below the Low result.

This specific combination of the Intel Core i5-12600KF and NVIDIA GeForce RTX 4080 SUPER ranks 101 out of 1769 tested combos in Pc Building Simulator, placing it in the 94.3rd percentile of all configurations. This is a strong result, but the ranking does not tell the whole story given the game's modest hardware demands. The rank reflects the combo's ability to sustain high frame rates across all settings, with even the lowest result (4K Ultra at 72.1 FPS) remaining playable.

The CPU's percentile vs all CPUs is 84, and its average benchmark score of 27827 places it in the same performance class as the Intel Core i9-10900K (27829, deltaPct 0) and just behind the Intel Core i5-12600K (27851, deltaPct -0.1). The GPU's percentile vs all GPUs is 88, with an average score of 53610 that edges out the AMD Radeon RX 6900 XT by 0.2% and the RTX 5070 Ti by 2.9%. These relative standings suggest that neither component is an outlier; rather, the combination benefits from both being above-average performers in their respective categories.

The rank of 101 out of 1769 puts this combo ahead of the vast majority of tested systems, but it is not the top-tier configuration. The data does not specify which combos rank higher, but the implication is that systems with more powerful CPUs (such as the i9-10900K, which matches this CPU's score) or faster GPUs would achieve higher ranks. In Pc Building Simulator, where the CPU and GPU both contribute to frame generation, this combo's rank reflects a balanced pairing that excels at high-refresh 1440p and solid 4K gameplay.

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 produce frame rates well above 200 FPS, making this resolution ideal for high-refresh monitors. The difference between Low (392.7 FPS) and Ultra (224.6 FPS) is 168.1 FPS, but both are far beyond what any current display can show. For 1080p, Ultra settings provide the best visual quality without any practical performance penalty, as the 224.6 FPS average would only be constrained by a 240 Hz monitor's limit.

At 1440p, the recommendation is High settings, which deliver 147.9 FPS. This is slightly above the 144 Hz refresh rate that is common for 1440p monitors, making it the sweet spot. Ultra settings at 1440p produce 142.2 FPS, a marginal 3.8% reduction from High, so users with 144 Hz displays could choose Ultra without noticing a difference. Medium settings at 1440p (207.4 FPS) are excessive for most displays, and Low (297.4 FPS) is unnecessary unless targeting 240 Hz or higher.

For 4K, the data suggests Medium settings as the best balance, with an average of 108.6 FPS. This is well above the 60 FPS target for most 4K displays and leaves headroom for frame drops. High settings at 4K (78.8 FPS) are also viable for 60 Hz displays, while Ultra (72.1 FPS) is the maximum visual quality but falls below the 75 Hz threshold that some 4K monitors use. Low settings at 4K (152.2 FPS) are not recommended, as the visual degradation outweighs any benefit when Medium already exceeds 100 FPS. The data indicates that Medium at 4K is the most efficient preset, offering a 50.7% FPS increase over Ultra while maintaining a higher visual fidelity than Low.
