Pc Building Simulator

Resolution Scaling

Pc Building Simulator shows a steep and predictable performance curve as resolution climbs, and the pattern here is textbook GPU-bound scaling. At 1080p with Low settings, the combo produces 206.4 FPS, which drops to 127.4 FPS at 1440p and then to 69.8 FPS at 4K. That is a 38% reduction from 1080p to 1440p, and another 45% drop from 1440p to 4K. The scaling is nearly linear with pixel count, which tells you the graphics card is doing the heavy lifting at every step.

The gap between Low and Ultra settings widens dramatically at higher resolutions. At 1080p, the spread from Low (206.4 FPS) to Ultra (95.3 FPS) is about 111 FPS. At 1440p, that spread narrows to roughly 68 FPS (127.4 vs. 59.6). At 4K, the spread compresses further to about 40 FPS (69.8 vs. 29.4). This compression is the classic signature of a GPU that is running out of headroom — when the card is already saturated at 4K, changing settings has less absolute impact because the bottleneck is raw pixel throughput, not shading complexity.

What this means for the limiting component is straightforward: the RX 6600 is the constraint in this pairing. The i7-14700K is nowhere near its limits, as evidenced by the fact that even at 4K Ultra the frame rate is a playable-but-not-smooth 29.4 FPS, which is far below what a modern CPU would bottleneck at. The 1080p Low result of 206.4 FPS is a strong indicator that the CPU can feed the GPU far more frames than the card can render. If you were to pair this CPU with a stronger GPU, you would see proportionally larger gains at 1080p than at 4K, where the GPU would still be the wall.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with a Navi 23 chip, fabricated on TSMC's 7 nm process. Its specifications are modest by modern standards: 8 GB of GDDR6 memory on a 128-bit bus, delivering 224.0 GB/s of bandwidth. The base clock is 1626 MHz, with a boost clock of 2491 MHz and a game clock of 2044 MHz. The card has 1792 shading units, 112 TMUs, and 64 ROPs, with 28 ray accelerators. Peak FP32 throughput is 8.928 TFLOPS.

In Pc Building Simulator, the 8 GB VRAM capacity is not the limiting factor at any tested setting, since even 4K Ultra stays within memory limits — the card does not stutter or exhibit the kind of frame-time spikes that VRAM overflow typically produces. Instead, the raw compute throughput is what governs performance. The 4K Ultra result of 29.4 FPS aligns closely with what you would expect from a card in the 69th percentile of all GPUs, which is exactly where this RX 6600 sits according to its percentileVsAllGpus score of 69.

The boost clock behavior is worth noting. The card's boost of 2491 MHz is relatively high for the segment, and it helps at 1080p where the GPU is not fully saturated. At 1440p and above, the sustained clock is more likely to settle near the game clock of 2044 MHz, which is why the 1440p High result of 63.3 FPS is only 60% of the 1080p High result of 105 FPS. The memory bandwidth of 224.0 GB/s is adequate for this game's art style and scene complexity, but it does contribute to the steep 4K falloff — the 128-bit bus has to work harder to feed the shaders at higher pixel counts.

How This Combo Ranks

This specific pairing of the Intel Core i7-14700K with the AMD Radeon RX 6600 ranks 1439 out of 1769 tested combos in Pc Building Simulator. That places it in the bottom 19% of all combinations, which on the surface sounds poor, but context matters. This ranking is dominated by the GPU's modest standing — the RX 6600 sits at the 69th percentile of all GPUs, while the CPU is at the 96th percentile of all CPUs. The combo rank of 1439 reflects the weaker link, and the data supports that interpretation.

Looking at the CPU's nearest rivals, the i7-14700K scores an average benchmark of 70074, which is essentially tied with the i7-14700KF (70104, 0% delta) and the AMD EPYC 9115 (69887, +0.3% delta). It trails the AMD Ryzen 9 9950X (70420, -0.5% delta) and the Intel Xeon Platinum 8270 (71056, -1.4% delta) by negligible margins. None of these differences would be perceptible in a game like Pc Building Simulator, where the GPU is the bottleneck. The CPU's raw multi-threaded muscle — a Cinebench R23 multi-core score of 44534 — is far beyond what this game needs.

The GPU's nearest rivals tell a different story. The RX 6600's average benchmark score of 25235 is within 0.5% of the AMD Radeon 890M (25246, 0% delta), the AMD Radeon RX 580 2048SP (25287, -0.2% delta), the AMD Radeon RX 6700M (25180, +0.2% delta), and the NVIDIA GeForce RTX 3060 Ti (25120, +0.5% delta). This is a tightly clustered group, which means the RX 6600's performance in this game is representative of a broad mid-range tier. The 1439 rank is therefore not an outlier — it is exactly where a 69th-percentile GPU with a 96th-percentile CPU should land in a GPU-bound title.

Measured FPS Breakdown

At 1920x1080, the combo delivers 206.4 FPS on Low, 148.8 FPS on Medium, 105 FPS on High, and 95.3 FPS on Ultra. The jump from Low to Medium is a 28% reduction, while Medium to High is a 29% reduction, and High to Ultra is a 9% drop. This is a well-behaved scaling curve — the game is not hitting any hard ceiling until Ultra, where the RX 6600's shading throughput starts to matter more than memory bandwidth.

At 2560x1440, the results are 127.4 FPS on Low, 95 FPS on Medium, 63.3 FPS on High, and 59.6 FPS on Ultra. The Medium-to-High drop of 33% is steeper than at 1080p, indicating that the GPU is beginning to feel the pixel load. The High-to-Ultra gap narrows to just 6%, which is unusually small — this suggests that Ultra settings at 1440p are not adding much shading complexity beyond High, or that the card is hitting a memory bandwidth wall that Ultra settings do not meaningfully worsen.

At 3840x2160, the numbers are 69.8 FPS on Low, 46.8 FPS on Medium, 36.3 FPS on High, and 29.4 FPS on Ultra. The Low-to-Medium drop is 33%, Medium-to-High is 22%, and High-to-Ultra is 19%. The scaling is more uniform here because the GPU is fully saturated at every setting level — each incremental setting increase directly reduces frame rate because there is no spare compute capacity. The 4K Low result of 69.8 FPS is the only 4K configuration that approaches a smooth 60 FPS experience, and even that is marginal.

CPU Role

The Intel Core i7-14700K is a 20-core, 28-thread processor based on Raptor Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. It has 80 KB of L1 cache per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. The CPU supports both DDR4 and DDR5 memory in dual-channel configuration, and it carries Intel's UHD Graphics 770 integrated GPU, although that is irrelevant for this discrete-GPU setup.

In Pc Building Simulator, the CPU's role is almost entirely about maintaining a high enough frame ceiling so that the GPU is never starved. The 1080p Low result of 206.4 FPS demonstrates that the i7-14700K can feed the RX 6600 well beyond its rendering limits — the card cannot physically produce more frames, so the CPU is idle much of the time. Even at 1080p Ultra, the 95.3 FPS result is far below what this CPU could sustain with a faster GPU.

The CPU's benchmark scores reinforce this. A Cinebench R23 multi-core score of 44534 and a single-core score of 6287 place it in the 96th percentile of all CPUs. Its PassMark multi-thread score of 52392 and single-thread score of 4472 are similarly strong. In a simulation game like Pc Building Simulator, which is not known for heavy multi-threaded workloads, the single-core performance is what matters most, and the 6287 single-core score is more than adequate. The 20 cores and 28 threads are essentially overkill for this title — they will not hurt, but they will not help frame rates either.

Settings Recommendations

For a smooth 60 FPS experience, the data points to 1080p High as the best balance. At 105 FPS, it provides a 68% headroom above the 60 FPS target, with visual quality that is only 10% slower than Ultra. The 1080p Ultra result of 95.3 FPS is also viable, but the 9% performance cost buys you almost nothing in a game that is not visually demanding at the margin. If you have a 1440p monitor, 1440p Medium at 95 FPS is the better choice than 1440p High at 63.3 FPS — the 33% FPS penalty for High is not worth it unless you insist on maximum detail.

For 4K, the situation is more constrained. 4K Low at 69.8 FPS is the only 4K setting that clears 60 FPS, and it does so by a slim margin. 4K Medium at 46.8 FPS is playable but not smooth, and 4K High at 36.3 FPS is borderline. Given the RX 6600's 8 GB VRAM and 224.0 GB/s bandwidth, 4K is not a realistic target for this card beyond Low settings. If 4K is your goal, you would need to accept Low settings or consider a GPU upgrade — this pairing is fundamentally a 1080p and 1440p solution.

The best overall experience per the measured rows is 1080p High at 105 FPS. It offers a wide margin over the 60 FPS threshold, retains most of the visual quality of Ultra, and leaves enough GPU headroom to avoid frame-time spikes. For competitive or high-refresh play, 1080p Low at 206.4 FPS is the clear pick, but for a simulation game where you are likely building PCs rather than racing, the visual fidelity of High is worth the FPS trade-off. At 1440p, stick with Medium unless you prioritize eye candy over frame rate — 95 FPS on Medium is a better experience than 59.6 FPS on Ultra.
