Pc Building Simulator

This combination of an Intel Core i3-12100F with an AMD Radeon RX 7900 XTX produces one of the more lopsided performance profiles in the database for Pc Building Simulator. The data shows a system that is overwhelmingly GPU-bound at higher resolutions but reveals a significant CPU limitation at 1080p, where frame rates are exceptionally high yet still constrained. The measured FPS across all settings and resolutions indicates that this pairing is viable for high-refresh-rate gaming, but the bottleneck shifts decisively depending on the target resolution.

Resolution Scaling

The performance drop from 1080p to 4K is dramatic and clearly illustrates where the system’s limits lie. At 1080p with Low settings, the combination produces 345.6 FPS, which is the absolute ceiling measured for this hardware. Moving to 1440p at the same Low preset, the frame rate falls to 267.8 FPS, a reduction of 77.8 FPS. At 4K, the same Low settings yield 141.3 FPS, which is a 204.3 FPS drop from the 1080p result. This steep decline is classic evidence of the GPU becoming the primary limiting factor as pixel count rises.

The scaling pattern is consistent across all settings. At Ultra, the system delivers 204.5 FPS at 1080p, 130.4 FPS at 1440p, and 65.1 FPS at 4K. The 4K Ultra result is less than one-third of the 1080p Low result, confirming that the RX 7900 XTX is being pushed to its limits at 3840x2160. In contrast, the gap between 1080p and 1440p at Ultra is 74.1 FPS, while the gap between 1440p and 4K is 65.3 FPS. This suggests that the GPU’s memory bandwidth of 960.0 GB/s and its 24 GB of GDDR6 memory are sufficient for the task, but raw compute throughput at 4K becomes the bottleneck.

The interesting nuance is that at 1080p, the frame rates are so high that the CPU’s 4 cores and 8 threads begin to matter. With a boost clock of 4.30 GHz, the i3-12100F is not slow, but the data implies that the CPU is holding back the GPU from reaching even higher numbers at lower resolutions. The fact that 1080p Low (345.6 FPS) is only 44.3 FPS higher than 1080p Medium (301.3 FPS) — while the 1440p gap between Low and Medium is 79.7 FPS — indicates that at 1080p, the CPU is nearing its limit. The GPU has more headroom, but the processor cannot feed it fast enough.

FAQ

Q: What is the best resolution for this combo to maintain a high refresh rate?

A: The data shows that 1440p is the sweet spot. At High settings, the system achieves 135.6 FPS, which is well above 120 FPS. At 4K High, the average drops to 69.4 FPS, which is below the 90 FPS threshold many users prefer. 1080p is faster, but the CPU bottleneck becomes more apparent.

Q: Does the CPU bottleneck the GPU at any resolution?

A: Yes, the evidence points to a CPU limit at 1080p. The 1080p Low result of 345.6 FPS and the 1080p Medium result of 301.3 FPS show a smaller relative difference than the 1440p equivalents (267.8 FPS vs 188.1 FPS). This compression suggests the i3-12100F’s 4 cores are saturated at lower resolutions.

Q: How does the 4K Ultra performance compare to 1080p Low?

A: The 4K Ultra average of 65.1 FPS is just 18.8 percent of the 1080p Low average of 345.6 FPS. This massive reduction underscores the GPU’s workload scaling with resolution and settings.

Q: Is this combo more GPU-limited or CPU-limited overall?

A: The overall profile is GPU-limited, especially at 1440p and 4K. The RX 7900 XTX, with its 61.39 TFLOPS FP32 performance, is the dominant component. The CPU only becomes a factor at 1080p, where frame rates exceed 200 FPS.

Q: What is the ranking of this combo among all tested combinations?

A: In Pc Building Simulator, this combo ranks 249 out of 1769 tested combinations. This places it in the top 14 percent of all tested combos, indicating strong overall performance.

Q: How does the GPU’s performance percentile compare to the CPU’s?

A: The RX 7900 XTX sits at the 85th percentile among all GPUs, while the i3-12100F is at the 72nd percentile among all CPUs. This 13-point gap confirms that the GPU is the stronger component relative to its peers.

Settings Recommendations

The measured data supports a clear recommendation: use High settings at 1440p for the best balance of visual quality and performance. At 1440p High, the system produces 135.6 FPS, which is smooth for most monitors. The jump to Ultra at the same resolution costs only 5.2 FPS on average (130.4 FPS), so Ultra is also viable if maximum quality is preferred. The difference between High and Ultra at 1440p is minimal, making Ultra the better choice for users who want the best image quality without a meaningful frame rate penalty.

At 4K, the situation is different. High settings yield 69.4 FPS, which is playable but not ideal for competitive play. Medium at 4K provides 100.3 FPS, offering a substantial improvement over High. The data suggests that 4K Medium is the most practical choice for 4K gaming, as it maintains a triple-digit frame rate while still delivering decent visuals. Low at 4K (141.3 FPS) is an option for those prioritizing frame rate over quality, but the visual compromise is significant.

For 1080p, the recommendation is to use Ultra settings. The system delivers 204.5 FPS at 1080p Ultra, which exceeds the refresh rate of most 1080p displays. Dropping to Low at 1080p (345.6 FPS) offers no practical benefit because the frame rate is already far beyond what most monitors can display. Users should prioritize visual fidelity at 1080p, as the hardware has more than enough headroom.

Measured FPS Breakdown

At 1920x1080, the system delivers consistently high frame rates across all presets. Low settings produce 345.6 FPS, Medium produces 301.3 FPS, High produces 214.2 FPS, and Ultra produces 204.5 FPS. The progression from Low to Medium shows a 44.3 FPS drop, while the drop from Medium to High is 87.1 FPS. The gap between High and Ultra is just 9.7 FPS, suggesting diminishing returns at the highest preset.

At 2560x1440, the frame rates remain strong but show a steeper decline with higher settings. Low produces 267.8 FPS, Medium drops to 188.1 FPS, High falls to 135.6 FPS, and Ultra bottoms out at 130.4 FPS. The difference between Low and Medium is 79.7 FPS, while the gap between Medium and High is 52.5 FPS. The High to Ultra transition costs only 5.2 FPS, indicating that the Ultra preset is not particularly demanding compared to High.

At 3840x2160, the GPU workload becomes apparent. Low settings yield 141.3 FPS, Medium yields 100.3 FPS, High yields 69.4 FPS, and Ultra yields 65.1 FPS. The drop from Low to Medium is 41 FPS, and the drop from Medium to High is 30.9 FPS. The High to Ultra gap is just 4.3 FPS, which is the smallest difference between any two consecutive presets at any resolution. This suggests that the Ultra preset adds little visual benefit at 4K while still incurring a performance cost.

How This Combo Ranks

The combo ranks 249 out of 1769 tested combinations in Pc Building Simulator, placing it in the top 14 percent of all combos. This is a strong result, but the ranking is influenced by the CPU’s relative weakness. The RX 7900 XTX sits at the 85th percentile among all GPUs, while the i3-12100F is at the 72nd percentile among all CPUs. The combo’s ranking of 249 suggests that many other pairings with stronger processors achieve higher overall scores, even if their GPUs are less powerful.

The benchmark data supports this interpretation. The CPU’s average benchmark score of 13516 places it nearly equal to the AMD Ryzen Threadripper PRO 3975WX, which scores 13534 with a delta of -0.1 percent. The i3-12100F is also within 0.4 percent of the Intel Core i7-1250U and 0.6 percent of the Intel Core i3-10105. These rivals are all in the same performance tier, confirming that the i3-12100F is a mid-tier processor despite its low core count.

The GPU’s average benchmark score of 44019 is more distinctive. The nearest rival, the AMD Radeon Pro 580, scores 44195 with a delta of -0.4 percent. The NVIDIA GeForce RTX 4090 Mobile scores 43667 with a delta of 0.8 percent, and the NVIDIA Quadro M6000 scores 43313 with a delta of 1.6 percent. The RX 7900 XTX outperforms all of these, but its position in the 85th percentile shows that there are still many GPUs above it.

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor from the Alder Lake architecture, built on a 10 nm process. Its base clock of 3.30 GHz and boost clock of 4.30 GHz provide solid single-thread performance, as evidenced by its 3dmark single-thread score of 893 and passmark single-thread score of 3444. The 12 MB of shared L3 cache and 1.25 MB per-core L2 cache are modest but adequate for this game.

In Pc Building Simulator, the CPU’s role is most evident at 1080p. The fact that 1080p Low and 1080p Medium produce 345.6 FPS and 301.3 FPS, respectively, shows that the CPU can drive high frame rates, but the relatively small gap between these settings suggests a limit. The CPU’s cinebench r23 multicore score of 11912 and passmark multithread score of 14015 are respectable for a 4-core part, but they are not enough to fully saturate the RX 7900 XTX at lower resolutions.

The CPU’s 3dmark 8-thread score of 4026 and 3dmark max-thread score of 4023 indicate that the processor reaches its performance ceiling with all threads active. This is relevant for Pc Building Simulator, which may not utilize more than 8 threads. The CPU’s 72nd percentile ranking among all CPUs confirms that it is above average, but it is the weaker component in this pairing.

GPU Role

The AMD Radeon RX 7900 XTX is a flagship GPU based on the RDNA 3.0 architecture and the Navi 31 chip, built on a 5 nm process at TSMC. It features 24 GB of GDDR6 memory on a 384-bit bus, providing 960.0 GB/s of bandwidth. With 6144 shading units, 384 TMUs, and 192 ROPs, the GPU delivers 61.39 TFLOPS of FP32 performance. Its boost clock of 2498 MHz and game clock of 2365 MHz are high, but the key metric is its ability to maintain performance at 4K.

The measured FPS data shows that the GPU is the dominant factor in this combo. At 4K Ultra, the system produces 65.1 FPS, which is a demanding workload. The GPU’s passmark g3d score of 31238 and 3dmark steel nomad score of 6841 place it at the 85th percentile among all GPUs. Its nearest rivals include the NVIDIA GeForce RTX 4070 Ti, which scores 44900 with a delta of -2 percent, meaning the RX 7900 XTX is 2 percent slower than that card on average.

The GPU’s memory configuration is particularly well-suited to Pc Building Simulator. The 24 GB VRAM capacity and 960.0 GB/s bandwidth ensure that texture-heavy scenes at 4K Ultra do not cause memory-related stutters. The 192 ROPs and 479.6 GPixel/s pixel rate allow for efficient rasterization, which is critical at 4K. The GPU’s role is to provide the raw throughput needed for high-resolution gaming, and the data confirms it does so admirably, even if the CPU limits its potential at lower resolutions.
