Pc Building Simulator

The Intel Core i5-14600K paired with the AMD Radeon RX 6650 XT delivers a performance profile in Pc Building Simulator that is heavily dictated by resolution and settings, with the data revealing a clear transition from a CPU-bound scenario at lower resolutions to a GPU-bound one at 4K. The measured FPS range from 233.5 at 1080p Low to 40.1 at 4K Ultra, illustrating how this combination scales across the tested spectrum. The analysis below breaks down these results, the roles of the core components, and where this pairing ranks among the 1,769 tested combos.

Resolution Scaling

The FPS drop from 1080p to 4K is steep, and the pattern across settings indicates that the Radeon RX 6650 XT becomes the limiting factor at higher pixel counts. At 1080p with Low settings, the combo produces 233.5 FPS, but at 4K Low, it falls to 75.3 FPS — a reduction of approximately 68% as pixel count quadruples. This scaling is expected for a GPU with an 8 GB GDDR6 memory buffer and a 128-bit bus, where fill-rate and memory bandwidth constraints become more pronounced at higher resolutions.

The data shows that the gap between 1080p and 1440p is significant but manageable, while the jump to 4K is punishing. For instance, at High settings, the average FPS drops from 120.2 at 1080p to 75.5 at 1440p, then to 42 at 4K. The step from 1440p to 4K represents a 44% decline, whereas the step from 1080p to 1440p is a 37% decline. This suggests that the GPU’s 280.3 GB/s bandwidth and 10.79 TFLOPS FP32 throughput are adequate for 1080p and playable at 1440p, but at 4K, the architecture’s limits are exposed.

At Ultra settings, the scaling is even more telling: 111 FPS at 1080p, 67.7 at 1440p, and 40.1 at 4K. The 4K Ultra result is below the 42 FPS recorded at 4K High, indicating that the extra shading and texture work at Ultra pushes the GPU past its comfort zone. Conversely, the CPU’s influence is most visible at 1080p Low, where the 233.5 FPS figure suggests that the Core i5-14600K’s 14 cores and 20 threads are not the bottleneck—the GPU is still able to feed frames at a high rate, but the headroom for even higher FPS is likely constrained by the graphics card’s pixel rate of 168.6 GPixel/s.

CPU Role

The Intel Core i5-14600K is a 14-core, 20-thread processor based on Raptor Lake architecture, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. Its 24 MB of shared L3 cache and support for both DDR4 and DDR5 memory make it a versatile component, but in Pc Building Simulator, the CPU’s role is primarily to feed the GPU with draw calls and simulation data. The game’s simulation genre often relies on single-threaded performance for logic, but the data shows that the CPU is not the limiting factor in most scenarios.

Benchmark results for the i5-14600K show a Cinebench R23 multicore score of 32881 and a single-core score of 4642, placing it in the 93rd percentile against all CPUs. Its nearest rival, the AMD Ryzen 9 5950X, scores 49062 on average, a delta of 0.2%, meaning the i5-14600K is statistically tied with a 16-core processor. This strong multicore performance is relevant because Pc Building Simulator can utilize multiple threads for background tasks, but the measured FPS at 1080p Low (233.5) suggests the CPU is not saturated—otherwise, we would see a plateau regardless of resolution.

The CPU’s boost clock of 5.30 GHz is likely the key driver for the high FPS at 1080p Low, where per-thread performance matters most. At 4K, however, the CPU’s influence diminishes, as the FPS drops to 75.3 at Low settings, which is nearly identical to the 75.5 FPS at 1440p High. This indicates that the GPU is the bottleneck at 4K, regardless of settings, and the CPU’s headroom is wasted at that resolution. In practical terms, the i5-14600K provides ample compute for this game, and users upgrading from older CPUs would see little benefit in this title beyond the already high baseline.

GPU Role

The AMD Radeon RX 6650 XT, based on the Navi 23 chip with RDNA 2.0 architecture, is the primary performance driver in this combo. It features 2048 shading units, 128 TMUs, and 64 ROPs, with a boost clock of 2635 MHz and a game clock of 2410 MHz. The 8 GB of GDDR6 memory on a 128-bit bus delivers 280.3 GB/s of bandwidth, which is sufficient for 1080p and 1440p but strained at 4K. The GPU’s compute throughput of 10.79 TFLOPS FP32 and pixel rate of 168.6 GPixel/s align with the observed scaling: at 1080p, the GPU can sustain high FPS, but as resolution increases, the pixel fill and memory bandwidth requirements outpace its capabilities.

The RX 6650 XT’s benchmark scores place it in the 72nd percentile against all GPUs, with a Passmark G3D score of 17166 and a 3DMark Steel Nomad DX12 score of 1859. Its nearest rival, the AMD Radeon RX 6800M, scores 29011 on average, a delta of 0%, meaning the RX 6650 XT is effectively tied with a mobile flagship. This parity is notable because the RX 6800M typically has more memory bandwidth, yet in this game, the desktop card holds its own.

In Pc Building Simulator, the GPU’s memory size of 8 GB is a limiting factor at 4K Ultra, where texture data can exceed the buffer, causing the FPS to drop to 40.1. At 1080p, the GPU is not the bottleneck, as evidenced by the 233.5 FPS at Low settings, but at 4K, the FPS across all settings (40.1 to 75.3) shows that the GPU is working at its limits. The 7 nm process node and 11,060 million transistors do not compensate for the narrow 128-bit bus, which is the primary constraint in this resolution scaling.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance across three resolutions and four settings levels. At 1920x1080, the combo delivers 233.5 FPS on Low, 164.4 on Medium, 120.2 on High, and 111 on Ultra. The gap between Low and Ultra is approximately 52%, indicating that the GPU is not heavily stressed at this resolution, and the CPU’s high boost clock helps maintain frame rates even at lower settings.

At 2560x1440, the results are 148.2 FPS on Low, 102.9 on Medium, 75.5 on High, and 67.7 on Ultra. The drop from Low to Ultra is about 54%, similar to 1080p, but the absolute numbers are lower, showing that the GPU is beginning to feel the resolution increase. The 1440p High result of 75.5 FPS is identical to the 4K Low result of 75.3 FPS, suggesting that the GPU’s performance ceiling is around this throughput level, regardless of how the workload is distributed between resolution and settings.

At 3840x2160, the FPS figures are 75.3 on Low, 52.7 on Medium, 42 on High, and 40.1 on Ultra. The difference between High and Ultra is just 1.9 FPS, indicating that the GPU is saturated and additional settings have minimal impact. The 4K Low result is still above 60 FPS, making it playable, but the 4K Ultra result of 40.1 FPS is below the 42 FPS at High, which shows a non-linear scaling where the Ultra preset’s extra effects cripple performance. Overall, the data indicates that 1080p is the sweet spot for this combo, with 1440p being viable at Medium or High, and 4K only playable at Low settings.

How This Combo Ranks

In the database of tested combinations, this CPU-GPU pairing ranks 1,138 out of 1,769 combos, placing it in the lower-middle tier of the distribution. This rank reflects the fact that while the CPU is strong (93rd percentile), the GPU is only in the 72nd percentile, and the combination’s overall performance is constrained by the graphics card. The rank of 1,138 means that approximately 36% of tested combos perform worse, while 64% perform better, indicating that this is a mid-range pairing suitable for 1080p gaming but not for high-refresh 1440p or 4K.

The CPU’s nearest rivals, such as the AMD Ryzen 9 5950X with a delta of 0.2%, show that the i5-14600K is well-matched with other high-end processors. However, the GPU’s nearest rivals, like the AMD Radeon RX 470 with a delta of 0.1%, demonstrate that the RX 6650 XT sits near the boundary between mid-range and lower-tier GPUs. This gap in component quality explains the combo’s mid-pack rank: the CPU provides headroom that the GPU cannot fully utilize at higher resolutions.

The data shows that this combo is best suited for 1080p Ultra (111 FPS) or 1440p High (75.5 FPS), but it falls short of the top-tier combos that would achieve higher ranks. The 4K results, with a maximum of 75.3 FPS on Low, are below the threshold for a smooth experience on high refresh rate monitors, and the rank reflects this limitation. For users targeting 1080p, this combo is effective, but for those seeking 4K performance, the GPU becomes the clear bottleneck, and the rank of 1,138 out of 1,769 underscores that this is a balanced but not exceptional pairing.
