Pc Building Simulator

Pc Building Simulator is a simulation title where the CPU and GPU interplay is unusual: the Intel Core i5-14400F and AMD Radeon RX 6650 XT combo shows a massive performance cliff at 4K, but the data indicates this is a GPU-bound scenario at high resolutions, not a CPU limitation. With a combo rank of 1121 out of 1769 tested configurations, this pairing sits in the lower-middle tier for this specific game, but the measured FPS reveals that it can deliver excellent 1080p performance at any preset, making it a capable 1080p machine that struggles to maintain smooth 4K gameplay.

Resolution Scaling

The data shows a steep performance drop as resolution increases, which points squarely at the GPU as the limiting component. At 1080p with High settings, the combo achieves 118 FPS, but at 1440p that falls to 74.4 FPS, and at 4K it plummets to 37 FPS. This represents a 68.6% reduction in frame rate from 1080p to 4K, a pattern consistent with a GPU that has enough raw throughput for lower resolutions but runs out of pixel-pushing capability at 4K.

The scaling across presets reinforces this diagnosis. At Low settings, the drop from 1080p (234.2 FPS) to 1440p (148.8 FPS) is 36.5%, and then to 4K (74.7 FPS) is another 49.8%. At Ultra settings, the falloff is even more pronounced: 110.6 FPS at 1080p, 72.1 FPS at 1440p, and just 34.4 FPS at 4K. The fact that the 4K Ultra result is less than one-third of the 1080p Low result (34.4 vs 234.2 FPS) suggests the RX 6650 XT is being overwhelmed by the combination of high resolution and demanding effects.

The pattern is clear: this combo is fully playable at 1080p and 1440p, but 4K is only viable at Low settings (74.7 FPS). The 37 FPS at 4K High is below the typical 60 FPS target, and the 34.4 FPS at 4K Ultra confirms that the GPU's 8 GB of VRAM and 280.3 GB/s bandwidth are insufficient for heavy 4K workloads in this simulation. The CPU is not the bottleneck here, as evidenced by the fact that even at 1080p Low, the frame rate reaches 234.2 FPS — a figure that would tax most CPUs but is achieved because Pc Building Simulator is not a particularly demanding title for the processor.

How This Combo Ranks

The combo rank of 1121 out of 1769 tested configurations places this pairing in the 36th percentile of all tested combos in Pc Building Simulator. This is a modest showing, but context matters: the CPU itself sits at the 88th percentile among all CPUs, while the GPU is at the 72nd percentile. The gap between these percentiles suggests the GPU is dragging the combo down in this specific game, which is consistent with the resolution scaling data showing GPU-bound behavior at higher resolutions.

The CPU's nearest rivals include the Intel Core i7-12800H (avg score 32513, deltaPct 0), the AMD Ryzen 5 PRO 7645 (avg score 32446, deltaPct 0.2), and the AMD Ryzen 7 250 (avg score 32584, deltaPct -0.2). The i5-14400F's avg benchmark score of 32508 is virtually identical to these competitors, with a deltaPct of 0% or less than a third of a percent in all cases. This means the CPU is performing exactly as expected for its class, and any combo ranking differences in this game come from the GPU or system-level factors.

On the GPU side, the RX 6650 XT's nearest rivals are the AMD Radeon RX 6800M (avg score 29011, deltaPct 0), the AMD Radeon RX 470 (avg score 28996, deltaPct 0.1), and the Intel Arc A370M (avg score 29175, deltaPct -0.5). The GPU's avg benchmark score of 29024 is again within 0.5% of these competitors. The fact that the combo ranks at 1121, while both components individually score near the top of their peer groups, indicates that the pairing is not the issue — rather, the game's demands at higher resolutions are simply beyond what this mid-range GPU can deliver.

GPU Role

The AMD Radeon RX 6650 XT features 8 GB of GDDR6 memory on a 128-bit bus, yielding a bandwidth of 280.3 GB/s. The memory clock runs at 2190 MHz (17.5 Gbps effective), while the GPU core boosts to 2635 MHz from a base of 2055 MHz, with a game clock of 2410 MHz. These specs place it in the 72nd percentile of all GPUs, but the 8 GB VRAM capacity is the critical factor in Pc Building Simulator's 4K performance.

The data shows that 4K High (37 FPS) and 4K Ultra (34.4 FPS) are nearly identical, which suggests the GPU is hitting a hard limit rather than scaling with settings. The 8 GB VRAM is likely being fully utilized at 4K, causing the GPU to spill over into system memory or reduce texture quality, which would explain the minimal difference between High and Ultra at 4K (37 vs 34.4 FPS). In contrast, at 1080p, the gap between High (118 FPS) and Ultra (110.6 FPS) is only 6.3%, indicating the GPU has enough VRAM headroom at that resolution.

The GPU's compute capabilities, measured at 10.79 TFLOPS FP32, are sufficient for 1440p gaming, as evidenced by the 1440p High result of 74.4 FPS. However, the 4K results show that doubling the pixel count from 1440p to 4K more than halves the frame rate in most settings, which is a classic sign of a GPU that is memory-bandwidth limited. The 128-bit bus and 280.3 GB/s bandwidth are simply not enough to feed the rendering pipeline at 4K resolutions in this simulation-heavy game.

Measured FPS Breakdown

At 1920x1080, the combo delivers strong results across all presets. Low settings produce 234.2 FPS, Medium gives 169.2 FPS, High reaches 118 FPS, and Ultra still manages 110.6 FPS. Even the most demanding preset at 1080p stays well above the 60 FPS threshold, making this a smooth experience at any setting. The spread from Low to Ultra is 123.6 FPS, which shows that Pc Building Simulator scales significantly with settings, but the GPU has enough headroom at 1080p to handle even the heaviest load.

Moving to 2560x1440, the frame rates remain playable but with a noticeable drop. Low yields 148.8 FPS, Medium drops to 108.1 FPS, High falls to 74.4 FPS, and Ultra bottoms out at 72.1 FPS. The difference between High and Ultra at 1440p is tiny (74.4 vs 72.1 FPS, a 3.1% gap), which suggests the GPU is starting to hit a performance ceiling where additional settings have diminishing returns. Medium at 108.1 FPS is the sweet spot for 1440p, offering a comfortable margin above the 60 FPS target.

At 3840x2160, the performance collapses. Low delivers 74.7 FPS, which is playable, but Medium drops to 55.6 FPS, High falls to 37 FPS, and Ultra manages just 34.4 FPS. The gap between Low and Medium at 4K is 19.1 FPS, which is significant, but the gap between High and Ultra is only 2.6 FPS. This compression at the top end indicates the GPU is completely saturated, and raising settings from High to Ultra yields almost no visual benefit because the rendering pipeline is already at its limit.

Settings Recommendations

The optimal preset depends on resolution, but the data clearly favors 1080p Ultra for the most complete experience. At 1080p, Ultra delivers 110.6 FPS, which is far above the 60 FPS target and only 7.4 FPS less than High (118 FPS). The 6.3% performance cost of going from High to Ultra at 1080p is worth it for the enhanced visual quality, especially since the frame rate remains exceptionally smooth.

For 1440p users, Medium is the recommended preset, delivering 108.1 FPS. This provides a 45.7% performance headroom over the 74.4 FPS at High, and the difference between Medium and High at this resolution is substantial (33.7 FPS). Since High and Ultra are nearly identical at 1440p (74.4 vs 72.1 FPS), there is no reason to select Ultra when High offers essentially the same frame rate. Medium at 1440p is the best balance of visual fidelity and performance.

At 4K, the only viable option is Low settings, which yields 74.7 FPS. Medium (55.6 FPS) dips below the 60 FPS threshold, and High (37 FPS) and Ultra (34.4 FPS) are unplayable for smooth gameplay. The data suggests that 4K is not a realistic target for this combo unless the user is willing to sacrifice settings significantly. For users who prioritize resolution over fidelity, 4K Low is acceptable, but 1440p Medium or 1080p Ultra will provide a better overall experience.

CPU Role

The Intel Core i5-14400F features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. It has 20 MB of shared L3 cache and supports both DDR4 and DDR5 memory, with ECC support. The CPU's benchmark scores are strong: Cinebench R23 multi-core reaches 21914, single-core hits 3093, and Geekbench multi-core scores 11209. These figures place it at the 88th percentile of all CPUs, with an avg benchmark score of 32508.

Despite this strong CPU performance, the data shows that Pc Building Simulator is not CPU-bound at the tested resolutions. The evidence is the 234.2 FPS at 1080p Low, which represents a scenario where the GPU's load is minimized, yet the frame rate is still very high. If the CPU were the bottleneck, we would expect to see similar frame rates across different resolutions at the same settings, but instead we see a dramatic drop from 1080p to 4K (e.g., High: 118 to 37 FPS).

The CPU's nearest rivals, including the Intel Core i7-12800H (deltaPct 0) and AMD Ryzen 5 PRO 7645 (deltaPct 0.2), show that the i5-14400F is performing exactly in line with its expected tier. The CPU's 65 W TDP and 10 nm process node allow it to maintain high clocks without excessive power draw, which is important for sustained gaming sessions. The 16 threads provide ample parallel processing for simulation games, and the 20 MB L3 cache helps with the frequent data access patterns typical of simulation titles.

In this specific game, the CPU's role is to feed the GPU with enough data to keep it busy, and the benchmark results indicate it does so effectively at 1080p and 1440p. The 4K performance drop is not a CPU issue — the GPU simply lacks the memory bandwidth and VRAM capacity to handle the higher pixel count. The data suggests that upgrading the GPU would yield significant gains at 4K, while keeping the same CPU would maintain current performance at 1080p and 1440p.
