Pc Building Simulator

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i7-14700KF is a 20-core, 28-thread processor built on the Raptor Lake-R architecture, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. This is a desktop-class chip with an unlocked multiplier, and it sits in the 96th percentile of all CPUs in the database, indicating that its raw compute capability is far above what most gaming workloads require. The processor carries a 33 MB shared L3 cache and 2 MB per-core L2 cache, along with 80 KB of L1 cache per core, which helps feed its 20 cores efficiently.

In Pc Building Simulator, the data suggests that the CPU is not the limiting factor at any tested settings. The game is a simulation title where the primary workload is managing PC components, and the benchmark results show that even at 1080p Low, the combination reaches 110.7 FPS. The i7-14700KF's multithreaded strength is evident in its Cinebench R23 multicore score of 44557 and Geekbench multicore score of 19287, but these numbers are far beyond what a simulation game with modest system requirements would need. The CPU's single-thread performance is also strong, with a Cinebench R23 single-core score of 6290, which matters for game logic and UI responsiveness.

The processor's 125 W TDP and dual-channel DDR4/DDR5 memory support are typical for a high-end desktop part, but the game itself does not appear to stress these capabilities. The benchmark results show that the i7-14700KF maintains consistent performance across resolutions, which implies that the CPU is ready to handle the simulation's background tasks while the GPU becomes the primary bottleneck at higher settings. The processor's PassMark multithread score of 52425 and single-thread score of 4480 reinforce that this is a top-tier compute part, but the game's FPS numbers are dictated more by the graphics card than by any CPU limitation.

The core count and clock speeds of the i7-14700KF are relevant here because the game is a simulation engine that often has to track multiple concurrent processes — part inventory, system temperature, and component compatibility checks. The 20 cores provide ample headroom for such tasks, and the boost clock of 5.60 GHz ensures that any single-threaded operations, like rendering the UI or calculating FPS estimates, run with minimal latency. The data shows no scenario where the CPU's capabilities are exhausted; the FPS drops from 1080p to 4K are entirely attributable to the GPU's rendering workload.

How This Combo Ranks

The combination of the Intel Core i7-14700KF and AMD Radeon RX 570 ranks 1677 out of 1769 tested combos in Pc Building Simulator. This places it in the bottom percentile of all tested configurations, which is a direct consequence of the pairing: a top-tier CPU with a mid-range GPU from an older generation. The rank reflects the overall FPS performance across all tested resolutions and settings, and the data indicates that this combo is heavily GPU-bound.

The CPU itself is not the problem — it outperforms its nearest rivals in the database. The i7-14700KF has an average benchmark score of 70104, which is essentially tied with the Intel Core i7-14700K at 70074 (a 0% delta) and slightly ahead of the AMD Ryzen 9 9950X at 70420 (a -0.4% delta, meaning the i7-14700KF is 0.4% behind). The AMD EPYC 9115 scores 69887, putting it 0.3% behind the i7-14700KF, and the Intel Xeon Platinum 8270 is 1.3% behind at 71056. These numbers show that the i7-14700KF is a competitive high-end CPU, but the combo rank is dragged down by the GPU.

The RX 570, by contrast, has an average benchmark score of 30158, which places it in the 74th percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce RTX 5060 at 30109 (0.2% behind), the AMD Radeon RX 7700 XT at 30097 (0.2% behind), the NVIDIA Tesla M60 at 29969 (0.6% behind), and the NVIDIA GeForce RTX 5070 Mobile at 29928 (0.8% behind). While the GPU's benchmark score is respectable, the game's FPS results show that it cannot keep up with the CPU's potential, especially at higher resolutions. The combo rank of 1677 out of 1769 is a clear signal that this pairing is unbalanced — the CPU is overqualified for the GPU's output.

This rank is not a measure of the CPU's failure but rather a statement about the pairing. In a game like Pc Building Simulator, where the simulation logic is light but the graphics rendering can be demanding, the RX 570 becomes the bottleneck at 1440p and 4K, and even at 1080p Ultra the FPS drops to 50.8. The data shows that a different GPU would yield a far better combo rank, but with this specific pairing, the results are limited by the graphics card's 4 GB of VRAM and GCN 4.0 architecture.

Resolution Scaling

The measured FPS data shows a clear pattern of performance degradation as resolution increases, which is a classic indicator of GPU-bound rendering. At 1080p Low, the combo achieves 110.7 FPS, but this drops to 66.8 FPS at 1440p Low — a reduction of 43.9 FPS, or roughly 40%. At 4K Low, the FPS falls to 34.7, which is a further 32.1 FPS drop from 1440p. This scaling is consistent with a GPU that has limited pixel throughput and memory bandwidth.

The trend holds across all settings. At Medium settings, 1080p yields 75.7 FPS, 1440p drops to 49.7 FPS, and 4K falls to 26.4 FPS. At High settings, the numbers are 55.5 FPS at 1080p, 31.8 FPS at 1440p, and 18.9 FPS at 4K. The Ultra settings show 50.8 FPS at 1080p, 34.9 FPS at 1440p, and 19.7 FPS at 4K. The FPS halving from 1080p to 4K at each setting is typical of a GPU that is saturating its rendering pipeline at higher resolutions.

This scaling behavior indicates that the CPU is not a bottleneck at any resolution. If the CPU were limiting performance, the FPS would remain relatively flat as resolution increases, because the CPU's workload is resolution-independent. Instead, the FPS drops proportionally with pixel count, which is the signature of a GPU that is running out of fill rate and bandwidth. The RX 570's 224.0 GB/s memory bandwidth and 39.81 GPixel/s pixel rate are the likely culprits, and the 4 GB VRAM capacity further constrains high-resolution textures.

The data also shows that the gap between Low and Ultra settings narrows as resolution increases. At 1080p, the difference between Low and Ultra is 59.9 FPS (110.7 vs. 50.8), but at 4K, the difference is only 15.0 FPS (34.7 vs. 19.7). This suggests that at 4K, the GPU is so heavily loaded that even reducing settings cannot fully compensate for the resolution overhead, whereas at 1080p, settings have a more pronounced impact on FPS.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce 110.7 FPS, which is the highest average FPS recorded in the dataset. Medium settings drop to 75.7 FPS, High settings yield 55.5 FPS, and Ultra settings fall to 50.8 FPS. The 1080p results are playable across all settings, though Ultra dips below 60 FPS, indicating that the GPU is nearing its limits even at the lowest resolution.

Moving to 2560x1440, the performance declines significantly. Low settings produce 66.8 FPS, which is still smooth, but Medium drops to 49.7 FPS, High falls to 31.8 FPS, and Ultra bottoms out at 34.9 FPS. The 1440p results show that only Low settings maintain a consistent 60+ FPS experience, while Medium and above fall below 50 FPS. This is a clear sign that the RX 570 is struggling with the increased pixel count.

At 3840x2160, the combo's performance becomes marginal for playability. Low settings produce 34.7 FPS, Medium drops to 26.4 FPS, High falls to 18.9 FPS, and Ultra is nearly identical at 19.7 FPS. None of the 4K results reach 60 FPS, and even Low settings barely exceed 30 FPS. The data shows that 4K is not a viable resolution for this pairing, as the GPU's 4 GB VRAM and 224.0 GB/s bandwidth are insufficient for the rendering load.

The Ultra settings at 1440p and 4K are noteworthy because they show nearly identical FPS (34.9 and 19.7, respectively) to High settings at the same resolutions (31.8 and 18.9). This suggests that the GPU is hitting a hard performance ceiling at these settings, likely due to memory bandwidth saturation or shader core exhaustion. The 1080p Ultra score of 50.8 FPS is the only Ultra result above 30 FPS, reinforcing that the RX 570 is best suited for 1080p gaming with moderate settings.

GPU Role

The AMD Radeon RX 570 is built on the Polaris 20 chip using GCN 4.0 architecture and a 14 nm process node, with 5,700 million transistors on a 232 mm² die. It operates at a base clock of 1168 MHz and a boost clock of 1244 MHz, with 2048 shading units, 128 texture mapping units, and 32 render output units. The GPU has 4 GB of GDDR5 memory on a 256-bit bus, providing 224.0 GB/s of bandwidth, and it delivers 5.095 TFLOPS of FP32 compute performance.

In Pc Building Simulator, the RX 570's role is to render the 3D environment, which includes PC cases, components, and the workspace. The game's graphics are not advanced, but the GPU's age and limited VRAM become apparent at higher resolutions and settings. The 4 GB VRAM is a particular constraint, as modern games at 1440p and 4K with High or Ultra textures can easily exceed this capacity, leading to texture thrashing and reduced FPS. The data supports this: at 4K Ultra, the combo only manages 19.7 FPS, which is nearly identical to 4K High at 18.9 FPS, suggesting that the GPU is not able to leverage any additional settings headroom.

The RX 570's benchmark scores place it in the 74th percentile of all GPUs, with an average score of 30158. Its nearest rivals are all within 0.8% of its score, indicating that the GPU is a mid-range performer in the database. However, the game's FPS results show that this GPU is not sufficient for high-refresh-rate or high-resolution gaming, especially when paired with a CPU that is vastly more powerful. The GPU's 150 W TDP and 450 W suggested PSU are modest, but the performance ceiling is the limiting factor.

The GPU's memory clock of 1750 MHz (7 Gbps effective) and 256-bit bus width provide adequate bandwidth for 1080p gaming, but the 224.0 GB/s becomes a bottleneck at 1440p and 4K. The pixel rate of 39.81 GPixel/s and texture rate of 159.2 GTexel/s are also limiting factors at higher resolutions. The data shows that the RX 570 is best utilized at 1080p with Low to Medium settings, where it can achieve 75.7 to 110.7 FPS, but any attempt to push higher resolutions or settings results in a significant FPS penalty. This is a classic example of a GPU that was designed for 1080p gaming in its era, and it cannot keep pace with a modern high-end CPU in a demanding rendering scenario.
