Pc Building Simulator

The Intel Core i5-12400F is a 6-core, 12-thread processor based on the Alder Lake architecture, built on Intel's 10 nm process. It has a base clock of 2.50 GHz and a boost clock of 4.40 GHz, with a 65 W TDP. Its cache layout includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3. In synthetic testing, this CPU posts a strong showing: a Cinebench R23 multi-core score of 16518 and a single-core score of 2332, alongside a Geekbench multi-core result of 9138. Its 3DMark single-thread score of 909 and max-thread score of 5912 illustrate a balanced design that favors high-frequency responsiveness over raw multi-thread throughput. The processor sits in the 77th percentile of all CPUs tested, with an average benchmark score of 19221.

For a simulation game like Pc Building Simulator, the CPU's role is foundational but not typically the bottleneck. The game's logic, component management, and system simulation rely on single-thread performance more than many other genres. The i5-12400F's single-core Cinebench R20 score of 979 and PassMark single-thread score of 3481 indicate it handles these serial tasks with ease. Its 12 threads provide headroom for background processes and game engine overhead, but the data shows that at lower resolutions, the GPU is the limiting factor. The CPU's 18 MB of shared L3 cache is generous for a mid-range part, reducing latency when the game accesses frequently used data. In this pairing, the i5-12400F is a capable air-cooled companion, providing enough processing power to keep the GPU fed without introducing frame pacing issues.

How This Combo Ranks

This specific combination of the Intel Core i5-12400F and the AMD Radeon RX 6600 ranks 1415 out of 1769 tested combos in Pc Building Simulator. That places it in the bottom 20% of all pairings, which is a direct reflection of the GPU's mid-range standing in this particular workload. The combo rank is not a measure of failure; it is a measure of where this hardware sits relative to the entire test pool, which includes far more expensive high-end cards. Benchmark results indicate that this pairing is positioned for 1080p gaming rather than high-resolution or maximum-fidelity play.

The CPU itself benchmarks closely to several rivals, with a delta of just 0.1% compared to the Intel Core i7-8700K, meaning the i5-12400F is effectively its equal in aggregate score. It is 0.3% ahead of the Intel Core i5-1335U and 1.3% ahead of the AMD EPYC 7773X. The only rival it trails is the AMD Ryzen 5 7533HS, which is 0.7% faster. These margins are negligible in real-world gaming terms, so the CPU is not holding this combo back. The RX 6600, however, shows a similar pattern: it is within 0.5% of the NVIDIA GeForce RTX 3060 Ti, 0.2% behind the AMD Radeon RX 6700M, and 0.2% ahead of the AMD Radeon RX 580 2048SP. The GPU is dead even with the AMD Radeon 890M, with a 0% delta. The ranking of 1415 is therefore driven by the GPU's absolute performance tier, not by a mismatch between the two components.

Resolution Scaling

The measured FPS data shows a classic GPU-bound scaling curve. At 1080p, the combo delivers 206.1 FPS on Low settings, which drops to 103.7 FPS on High and 96.3 FPS on Ultra. This is a 53% reduction from Low to Ultra at 1080p, indicating that visual settings have a massive impact on frame rate at this resolution. Moving to 1440p, the same settings produce 128.8 FPS on Low, 63.7 FPS on High, and 61.4 FPS on Ultra. The drop from 1080p Low to 1440p Low is 37.5%, while the drop from 1080p Ultra to 1440p Ultra is 36.2%. This consistent ~37% reduction across settings suggests the GPU is the primary limiter, as resolution scaling affects the pixel fill rate directly.

At 4K, the picture changes dramatically. High settings yield 33.9 FPS, Medium yields 49.7 FPS, and Ultra yields 34.5 FPS. The gap between High and Ultra at 4K is just 1.8%, while the gap between Medium and High is 31.8%. Low settings at 4K produce 70.6 FPS, which is still below the 1440p Low result of 128.8 FPS by 45.2%. The data shows that 4K is only playable on Low settings, and even then, it barely clears 60 FPS. The limiting component is unequivocally the GPU; the CPU's performance is constant across resolutions, so the FPS degradation from 1080p to 4K is entirely attributable to the RX 6600's 8 GB of GDDR6 memory and 128-bit memory bus, which struggles with the increased pixel workload.

FAQ

Q: What is the best resolution for this combo in Pc Building Simulator?

A: The data shows 1080p is the sweet spot. At 1080p High, the combo achieves 103.7 FPS, and at 1080p Ultra it still hits 96.3 FPS. At 1440p, High drops to 63.7 FPS, which is playable but less comfortable, and 4K High falls to 33.9 FPS.

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

A: The Intel Core i5-12400F has an average benchmark score of 19221, which is 0.1% higher than the Intel Core i7-8700K's score of 19210. It is also 0.3% ahead of the Intel Core i5-1335U and 1.3% ahead of the AMD EPYC 7773X.

Q: Is the GPU or CPU the bottleneck at 4K?

A: At 4K, the GPU is the clear bottleneck. The CPU's workload does not change with resolution, but the FPS drops from 103.7 at 1080p High to 33.9 at 4K High. This 67.3% reduction is caused by the RX 6600's rendering limits.

Q: What is the frame rate difference between High and Ultra settings?

A: At 1080p, High produces 103.7 FPS and Ultra produces 96.3 FPS, a difference of 7.1%. At 1440p, High gives 63.7 FPS and Ultra gives 61.4 FPS, a 3.6% difference. At 4K, High gives 33.9 FPS and Ultra gives 34.5 FPS, a difference of 1.8%.

Q: How does the GPU rank against all other GPUs?

A: The AMD Radeon RX 6600 is in the 69th percentile of all GPUs tested, with an average benchmark score of 25235. It is within 0.5% of the NVIDIA GeForce RTX 3060 Ti and 0.2% of the AMD Radeon RX 6700M.

Q: Can this combo handle 1440p gaming?

A: Yes, but with compromises. At 1440p Medium, the combo delivers 92.9 FPS, which is smooth, and High drops to 63.7 FPS. Ultra at 1440p is 61.4 FPS, so it is playable, but the 4K results suggest that 1440p Ultra is near the GPU's limit.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture using a 7 nm process from TSMC. It features 1792 shading units, 112 texture mapping units, and 64 raster operation pipelines. The GPU has a base clock of 1626 MHz, a boost clock of 2491 MHz, and a game clock of 2044 MHz. Memory is 8 GB of GDDR6 on a 128-bit bus, providing 224.0 GB/s of bandwidth. The card supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, with 28 ray accelerators for hardware ray tracing. Its pixel rate is 159.4 GPixel/s and texture rate is 279.0 GTexel/s, with an FP32 performance of 8.928 TFLOPS.

In Pc Building Simulator, the GPU's role is to render the 3D workshop environment, component models, and lighting effects. The benchmark results show that the RX 6600 is adequate for 1080p and playable at 1440p, but it runs out of steam at 4K. The 8 GB VRAM is sufficient for this game's texture loads at 1080p and 1440p, but the 128-bit memory bus limits effective bandwidth at high resolutions. The GPU's PassMark G3D score of 15096 and 3DMark Steel Nomad score of 1492 place it in the 69th percentile, which is solidly mid-range. Its nearest rival, the AMD Radeon RX 6700M, is only 0.2% faster, meaning the 6600 is well-positioned within its class.

Settings Recommendations

For the best experience, the data points to 1080p as the primary resolution. At 1080p High, the combo produces 103.7 FPS, which is smooth and visually detailed. Bumping to Ultra only costs 7.1% performance, yielding 96.3 FPS, so Ultra is the recommended setting for most users with a 60 Hz or 144 Hz monitor. At 1080p Medium, the frame rate jumps to 149 FPS, which is ideal for high-refresh-rate displays, but the visual fidelity loss may not be worth it for a simulation game where reading component details matters.

At 1440p, the recommendation shifts to Medium, which produces 92.9 FPS. High at 1440p drops to 63.7 FPS, which is playable but leaves little headroom for frame drops. Ultra at 1440p at 61.4 FPS is borderline; if you have a 60 Hz monitor, it is acceptable, but for competitive or smooth gameplay, Medium is safer. At 4K, the only playable setting is Low, which produces 70.6 FPS. Medium at 4K drops to 49.7 FPS, and High/Ultra fall below 35 FPS, which is not recommended. The measured rows indicate that the best experience is 1080p Ultra for visual quality, or 1440p Medium for a balance of resolution and frame rate. Avoid 4K unless you are willing to run Low settings.
