# Pc Building Simulator — Intel Core i3-12100F + AMD Radeon RX 6650 XT

The Intel Core i3-12100F paired with the AMD Radeon RX 6650 XT delivers a distinctly CPU-bound experience in Pc Building Simulator, a simulation title that rarely stresses the graphics pipeline as heavily as it does the processor. The measured frame rates across three resolutions and four quality presets reveal a system that scales predictably with resolution but shows diminishing returns at lower settings, where the CPU becomes the limiting factor. This combination sits at rank 1165 out of 1769 tested combos in the game, placing it in the lower-middle portion of the database. The CPU, a 4-core, 8-thread Alder Lake-S part with a base clock of 3.30 GHz and a boost clock of 4.30 GHz, holds the 72nd percentile among all CPUs, while the GPU, an RDNA 2.0 part with 2048 shading units and 8 GB of GDDR6 memory, also sits at the 72nd percentile among all GPUs. The data shows a system that can handle the game at high frame rates in most scenarios, but the balance between components shifts dramatically depending on the resolution and preset chosen.

Resolution Scaling

Frame rate drops from 1080p to 4K are steep but not uniform across settings, indicating where the bottleneck shifts. At Ultra settings, average FPS falls from 110.9 at 1920x1080 to 68 at 2560x1440, a 38.7% reduction, then further to 35.9 at 3840x2160, a 67.6% drop from the 1080p baseline. This pattern suggests the GPU is progressively more stressed as pixel count rises, with the 4K Ultra result falling below playable thresholds for most users. At Low settings, the scaling is even more dramatic in percentage terms: 236.7 FPS at 1080p drops to 149.6 at 1440p (a 36.8% reduction) and then to 75.9 at 4K (a 67.9% drop). The sheer magnitude of these drops — roughly two-thirds from 1080p to 4K regardless of preset — points to a component that is heavily resolution-dependent, which is the GPU.

However, the gap between Low and Ultra at each resolution tells a different story. At 1080p, the spread from Low (236.7 FPS) to Ultra (110.9 FPS) is 125.8 FPS, meaning the CPU can push very high frame rates when the GPU is underutilized. At 4K, the same spread narrows to 40 FPS (75.9 Low versus 35.9 Ultra), indicating the GPU is nearing its ceiling. The data suggests that at 1080p, the CPU is the primary limiter at Low and Medium settings, while the GPU becomes the limiter at Ultra. At 1440p, the balance is closer, with the CPU still able to deliver 149.6 FPS at Low but the GPU dropping to 68 at Ultra. At 4K, the GPU is firmly the bottleneck across all settings, as even Low settings yield only 75.9 FPS, far below the 236.7 FPS seen at 1080p.

GPU Role

The AMD Radeon RX 6650 XT, built on the Navi 23 chip with a 7 nm process from TSMC, brings 8 GB of GDDR6 memory on a 128-bit bus with 280.3 GB/s of bandwidth. Its clocks are substantial: a base of 2055 MHz, a game clock of 2410 MHz, and a boost clock of 2635 MHz. The memory runs at 2190 MHz, which translates to 17.5 Gbps effective. The GPU's 2048 shading units, 128 TMUs, and 64 ROPs give it a pixel rate of 168.6 GPixel/s and a texture rate of 337.3 GTexel/s, with FP32 performance of 10.79 TFLOPS. These specs position the card well above entry-level parts, and the benchmark data confirms this: its PassMark G3D score of 17166 and average benchmark score of 29024 place it at the 72nd percentile.

The GPU's nearest rivals in the database are the AMD Radeon RX 6800M (average score 29011, deltaPct 0.0), the AMD Radeon RX 470 (28996, deltaPct 0.1), the Intel Arc A370M (29175, deltaPct -0.5), and the AMD Radeon RX Vega M GH (29197, deltaPct -0.6). This clustering shows that the RX 6650 XT is essentially performance-equivalent to a high-end laptop GPU and a much older desktop part, with deltas under 1% in all cases. In Pc Building Simulator, the GPU's 8 GB VRAM is unlikely to be a constraint at any resolution tested, given the game's simulation genre and the fact that even 4K Ultra only produced an average of 35.9 FPS — a performance limit, not a capacity issue. The GPU's DirectX 12 Ultimate support (12_2) and Vulkan 1.4 compatibility are relevant, but the game's modest graphical demands mean the card's raw compute is more than sufficient; the frame rates are instead bounded by the CPU in many scenarios.

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor from the Alder Lake-S generation, manufactured on Intel's 10 nm process with a die size of 163 mm². It has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and a shared 12 MB L3 cache. Its base clock of 3.30 GHz and boost of 4.30 GHz are modest by modern standards, but its single-thread performance is strong: the 3DMark single-thread score is 893, and Cinebench R23 single-core reaches 1681. Multi-threaded scores are more limited by the core count: Cinebench R23 multi-core is 11912, and Geekbench multi-core is 7413, while PassMark multi-thread is 14015.

The CPU's average benchmark score of 13516 places it at the 72nd percentile, with nearest rivals including the AMD Ryzen Threadripper PRO 3975WX (avgScore 13534, deltaPct -0.1), Intel Core i7-1250U (13462, deltaPct 0.4), Intel Core i3-10105 (13430, deltaPct 0.6), and Intel Core i7-7700K (13280, deltaPct 1.8). These deltas are all within 2%, indicating that the i3-12100F's overall benchmark performance is comparable to a high-end workstation CPU, a mobile ultra-low-power part, and two older desktop chips. In Pc Building Simulator, the CPU's 4 cores and 8 threads appear sufficient to drive high frame rates at lower resolutions: at 1080p Low, the system reaches 236.7 FPS, which is likely CPU-bound given the GPU's capability. The 3DMark 4-thread score of 2859 and 8-thread score of 4026 suggest that the CPU can handle the game's simulation logic without becoming a hard bottleneck, but at 4K Ultra, the GPU's limitations dominate, and the CPU's role recedes.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce an average of 236.7 FPS, which is more than sufficient for any display. Medium drops to 163.5 FPS, High to 119 FPS, and Ultra to 110.9 FPS. The step from Low to Medium is a 73.2 FPS reduction, while the step from High to Ultra is only 8.1 FPS, suggesting diminishing returns at the top end. At 2560x1440, Low yields 149.6 FPS, Medium 104.9 FPS, High 73.4 FPS, and Ultra 68 FPS. The drop from Low to Medium is 44.7 FPS, and from High to Ultra is just 5.4 FPS. At 3840x2160, Low produces 75.9 FPS, Medium 53.5 FPS, High 37 FPS, and Ultra 35.9 FPS. Here, the Low-to-Medium gap is 22.4 FPS, and the High-to-Ultra gap is only 1.1 FPS, indicating that Ultra provides almost no benefit over High at this resolution.

The data reveals that at every resolution, the largest performance jump occurs when moving from Low to Medium, while the smallest is between High and Ultra. This pattern suggests that the Ultra preset in Pc Building Simulator imposes a significant overhead that yields marginal visual gains, particularly at higher resolutions. At 4K, the difference between High (37 FPS) and Ultra (35.9 FPS) is within measurement noise, making Ultra essentially unplayable and High barely playable. At 1440p, High (73.4 FPS) and Ultra (68 FPS) are both playable, but the 5.4 FPS difference does not justify the quality increase. At 1080p, all settings are playable, with even Ultra exceeding 110 FPS, so the choice comes down to visual preference rather than necessity.

FAQ

Q: Is this system capable of running Pc Building Simulator at 4K?

A: Yes, but only at Low settings, where it achieves 75.9 FPS. Medium drops to 53.5 FPS, High to 37 FPS, and Ultra to 35.9 FPS, meaning 4K gaming is only viable at the lowest preset.

Q: What is the best resolution for this combo?

A: 1440p offers the best balance: Low yields 149.6 FPS, Medium 104.9 FPS, and High 73.4 FPS, all of which are smooth. At 1080p, the system exceeds 110 FPS even at Ultra, but 1440p provides a sharper image without sacrificing playability.

Q: How does the CPU compare to its nearest rivals?

A: The i3-12100F has an average benchmark score of 13516, which is 0.1% below the AMD Ryzen Threadripper PRO 3975WX (13534), 0.4% above the Intel Core i7-1250U (13462), 0.6% above the Intel Core i3-10105 (13430), and 1.8% above the Intel Core i7-7700K (13280).

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

A: At Low and Medium settings, the CPU appears to be the limiter, as the GPU is capable of much higher frame rates than the 236.7 FPS and 163.5 FPS observed. At Ultra, the GPU becomes more involved, but the 110.9 FPS result still indicates a well-balanced system at that resolution.

Q: Is the 8 GB of VRAM sufficient for this game?

A: Yes, the game's simulation nature means it does not heavily utilize texture memory. The GPU's 8 GB of GDDR6 memory is not the limiting factor; the measured FPS drops are attributable to compute or bandwidth limits, not capacity.

Q: What is the GPU's performance rank relative to other cards?

A: The RX 6650 XT has an average benchmark score of 29024, placing it at the 72nd percentile. It is within 0.6% of the AMD Radeon RX 6800M, AMD Radeon RX 470, Intel Arc A370M, and AMD Radeon RX Vega M GH, all of which have average scores between 28996 and 29197.

Settings Recommendations

Based on the measured FPS rows, the optimal preset varies by resolution. At 1920x1080, Ultra is the clear choice: 110.9 FPS average is well above the threshold for smooth gameplay, and the difference from High (119 FPS) is only 8.1 FPS, so the visual quality gain is worth the small performance cost. Medium (163.5 FPS) and Low (236.7 FPS) are excessive for most displays, offering frame rates beyond what a typical 60 Hz or 144 Hz monitor can display. At 2560x1440, High (73.4 FPS) is the recommended preset, as it provides a solid frame rate while Ultra (68 FPS) drops below 70 FPS. The gap between High and Ultra is just 5.4 FPS, but High is more likely to maintain consistent performance during complex scenes. Medium (104.9 FPS) is also viable for players who prioritize frame rate over visuals, but High offers a better balance. At 3840x2160, only Low (75.9 FPS) is recommended for playable performance. Medium (53.5 FPS) is borderline, and High (37 FPS) and Ultra (35.9 FPS) are not suitable for smooth gameplay. The data indicates that the system's sweet spot is 1080p Ultra or 1440p High, with 4K reserved for Low settings only.
