Pc Building Simulator

Resolution Scaling

The measured frame rates show a steep and consistent penalty as resolution climbs, which is the classic signature of a GPU-bound simulation workload. At 1080p Low, the combo produces 208.7 FPS, but that falls to 128.6 FPS at 1440p and 67.9 FPS at 4K. The drop from 1080p to 1440p is a 38% reduction, while moving from 1440p to 4K costs another 47%. This is not a linear scaling; the curve steepens at higher resolutions, indicating the GPU's pixel throughput becomes the dominant constraint.

The Ultra preset tells a similar story. At 1080p Ultra, the average is 98.3 FPS. At 1440p Ultra, it drops to 59.5 FPS, and at 4K Ultra, it bottoms out at 31.6 FPS. The gap between 1440p and 4K Ultra is a 47% loss, nearly identical to the Low preset's proportional decline. This consistency across settings suggests that resolution scaling is independent of the graphical preset; the limiting factor is always the same component.

The data points to the GPU being the bottleneck at 4K. At 1080p Low, the frame rate of 208.7 FPS is high enough that the CPU could theoretically keep up, but the 4K Low result of 67.9 FPS shows the GPU cannot sustain that throughput when pixel count quadruples. The medium preset at 4K (49.3 FPS) and High at 4K (32.1 FPS) reinforce this: the GPU's rendering capacity is exhausted well before the CPU's logical limits. For a 4K display, this combo is only viable on Low settings, and even then, the 67.9 FPS average is below the 70 FPS threshold that many users consider smooth for fast-paced action.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor with a base clock of 2.90 GHz and a boost clock of 4.30 GHz. In synthetic benchmarks, it scores 10297 in Cinebench R23 multi-core and 1453 in single-core. These numbers place it in the 73rd percentile of all CPUs, which is respectable for a mid-range part. Its nearest rivals include the AMD Ryzen 3 7320C (0.8% slower) and the Intel Core i5-8500 (1.1% slower), showing it sits in a tight competitive cluster.

For Pc Building Simulator, the CPU role is secondary but not negligible. The game is a simulation, which typically involves physics calculations and logic updates that can stress multiple threads. The 12 threads of the i5-10400F are sufficient to handle these workloads; the benchmark data shows that at 1080p Low, the combo reaches 208.7 FPS, which is far beyond the 60 FPS target. At 1080p Ultra, the frame rate is 98.3 FPS, still comfortably high. This indicates that the CPU is not the primary limiter at mainstream resolutions.

The 3DMark results support this interpretation. The 16-thread score of 4748 and the 8-thread score of 3929 show that the processor scales well with thread count, but the single-thread score of 688 is modest. For a game that may have a primary simulation thread, the single-core performance of 1453 in Cinebench R23 is adequate but not exceptional. The data suggests that the CPU can deliver high frame rates when paired with a capable GPU, but it is the GPU that dictates the ceiling at higher resolutions. At 4K, the CPU's contribution is essentially irrelevant; the GPU is so bogged down that the processor's headroom goes unused.

FAQ

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

A: 1080p is the only resolution where the combo consistently exceeds 98 FPS across all presets. At 1440p, High settings yield 63.7 FPS, which is playable, but 4K Ultra drops to 31.6 FPS, which is not smooth.

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

A: The i5-10400F has an average benchmark score of 14168. It is 0.4% faster than the AMD EPYC 7552, 0.8% slower than the AMD Ryzen 3 7320C, and 1.1% slower than the Intel Core i5-8500.

Q: Is the GPU the bottleneck at 4K?

A: Yes. The frame rate drops from 208.7 FPS at 1080p Low to 67.9 FPS at 4K Low, a 67% reduction. The GPU's pixel throughput is the limiting factor, as the CPU has ample headroom at these frame rates.

Q: What is the GPU's percentile ranking?

A: The AMD Radeon RX 6600 sits in the 69th percentile of all GPUs. Its average benchmark score is 25235, putting it 0.2% ahead of the RX 580 2048SP and 0.5% behind the RTX 3060 Ti.

A: At 1080p, Ultra (98.3 FPS) is 6.7% slower than High (105.4 FPS). At 4K, Ultra (31.6 FPS) is 1.6% slower than High (32.1 FPS). The visual improvement is marginal compared to the frame rate cost.

Q: How many threads does the CPU have, and does it matter?

A: The i5-10400F has 12 threads. The 3DMark 16-thread score of 4748 versus the 2-thread score of 1350 shows good scaling, but the game's performance at 1080p Low (208.7 FPS) suggests that thread count is not a limiting factor for this title.

How This Combo Ranks

This configuration ranks 1436 out of 1769 tested combos for Pc Building Simulator. That places it in the bottom 19% of all combinations, which is a surprisingly low position given the individual component percentiles. The CPU is in the 73rd percentile, and the GPU is in the 69th percentile, yet the combo rank suggests that other pairings with similar or lower component scores perform better in this specific game.

The discrepancy likely stems from the game's engine characteristics. Pc Building Simulator is a simulation that may favor certain CPU architectures or GPU features that this combo lacks. The RX 6600 has 8 GB of GDDR6 memory and a 128-bit bus, which is modest for high-resolution textures. The CPU's 12 MB of L3 cache and dual-channel DDR4 memory support may also limit memory bandwidth in complex simulation scenes.

Relative to the field, this combo is not a top performer. The 1436 rank out of 1769 means that 333 other combinations deliver better measured results. However, the absolute frame rates are not poor: 105.4 FPS at 1080p High is fully playable. The rank reflects that many other hardware pairings achieve higher averages, not that this one is incapable. For users who already own these parts, the data shows that 1080p is the sweet spot, while 4K Ultra is not a realistic target.

Settings Recommendations

The measured data provides a clear hierarchy of settings. At 1080p, the Low preset delivers 208.7 FPS, Medium 147.7 FPS, High 105.4 FPS, and Ultra 98.3 FPS. The jump from Low to Medium is a 29% reduction, while Medium to High is a 29% reduction, and High to Ultra is a 7% reduction. The diminishing returns suggest that High is the best balance: it loses only 7% to Ultra but gains 7% over Medium.

At 1440p, the pattern shifts. Low gives 128.6 FPS, Medium 91.8 FPS, High 63.7 FPS, and Ultra 59.5 FPS. Here, Medium is the recommended preset because it stays above 90 FPS, while High drops below 65. The difference between High and Ultra is only 6.6%, meaning Ultra offers no meaningful advantage. At 4K, Low is the only viable option at 67.9 FPS; Medium drops to 49.3 FPS, and High falls to 32.1 FPS, which is below the 30 FPS floor for playability.

For the best experience, the data recommends 1080p High for maximum visual quality without sacrificing smoothness, or 1440p Medium for a higher resolution at a playable frame rate. 4K is only acceptable on Low settings, and even then, the 67.9 FPS average is borderline for a simulation that may have input lag. The Ultra preset is never worth the cost: it provides the lowest frame rates at every resolution with only marginal visual gains over High.

Measured FPS Breakdown

At 1920x1080, the combo delivers a wide range of performance. Low settings produce 208.7 FPS, Medium 147.7 FPS, High 105.4 FPS, and Ultra 98.3 FPS. The spread from Low to Ultra is 110.4 FPS, showing that the GPU has substantial headroom at this resolution.

At 2560x1440, the numbers compress. Low yields 128.6 FPS, Medium 91.8 FPS, High 63.7 FPS, and Ultra 59.5 FPS. The drop from Low to Ultra is 69.1 FPS. The High to Ultra gap is only 4.2 FPS, indicating that the GPU is nearing its limits.

At 3840x2160, the results are much tighter. Low gives 67.9 FPS, Medium 49.3 FPS, High 32.1 FPS, and Ultra 31.6 FPS. The difference between High and Ultra is just 0.5 FPS, confirming that the GPU is fully saturated. The Low to Ultra spread is 36.3 FPS, the smallest of any resolution.

The data shows that the combo scales predictably. At 1080p, the CPU can keep up, and the GPU determines the frame rate based on settings. At 4K, the GPU is the sole limiter, and the settings have less impact on the final result. The medium preset at 1440p (91.8 FPS) is the highest frame rate at that resolution that remains above 90, making it the most practical choice for high-refresh monitors.

GPU Role

The AMD Radeon RX 6600 is a RDNA 2.0 part with 8 GB of GDDR6 memory on a 128-bit bus, providing 224.0 GB/s of bandwidth. It has 1792 shading units and 64 ROPs, with a boost clock of 2491 MHz and a game clock of 2044 MHz. These specs place it in the 69th percentile of all GPUs, with an average benchmark score of 25235. Its nearest rivals are the AMD Radeon 890M (0% difference), the RX 580 2048SP (0.2% faster), and the RX 6700M (0.2% slower).

In Pc Building Simulator, the GPU's role is decisive. The 4K Ultra result of 31.6 FPS is a direct reflection of the 8 GB VRAM and 128-bit bus struggling with high-resolution textures. The 4K Low result of 67.9 FPS shows that even at minimal settings, the GPU cannot break past 70 FPS at this resolution. The 1080p Low result of 208.7 FPS demonstrates that the GPU has plenty of raw compute for lower pixel counts, but the memory bandwidth becomes a wall at higher resolutions.

The GPU's 64 ROPs and 279.0 GTexel/s texture rate are adequate for 1080p gaming, but the 224.0 GB/s bandwidth is a limiting factor at 1440p and 4K. The data shows that the RX 6600 is best suited for 1080p, where it delivers over 98 FPS on all presets. At 1440p, it remains playable on Medium (91.8 FPS) but struggles on High (63.7 FPS). At 4K, it is only usable on Low (67.9 FPS), and even that is marginal. The GPU is the bottleneck in this pairing, and the measured frame rates confirm that the CPU is not the constraint.
