Pc Building Simulator

Intel Core i7-13700K and Intel Arc B580 is a high-core-count CPU paired with a mid-range GPU that produces a heavily CPU-limited experience at lower resolutions in Pc Building Simulator, while the GPU becomes the clear bottleneck at 4K Ultra. The data shows a combination that is remarkably well-balanced for 1440p High and Medium settings, but the scaling pattern from 1080p to 4K reveals a system whose performance ceiling is dictated by whichever component is under the most stress at a given moment.

Resolution Scaling

The measured FPS data reveals a classic resolution-scaling curve, but with a distinctive shape that points directly to the bottleneck. Moving from 1920x1080 to 2560x1440 at High settings, the average frame rate drops from 109 FPS to 69 FPS, a reduction of 40 FPS or roughly 37%. This is a substantial drop, but it is not the steepest cliff in the data. The transition from 2560x1440 to 3840x2160 at High settings brings the average down from 69 FPS to 36 FPS, a 33 FPS decline, which is a 48% reduction in performance. This steeper drop at the higher resolution indicates that the GPU is starting to become the limiting factor as pixel count increases.

At Low settings, the scaling behavior is even more telling. The 1080p Low result is 217 FPS, which drops to 137 FPS at 1440p and then plummets to 72 FPS at 4K. The jump from 1440p to 4K at Low settings is a 65 FPS loss, the largest single-resolution delta in the entire dataset. This is significant because Low settings typically reduce GPU load, so a massive FPS drop when moving to 4K under those conditions signals that the Intel Arc B580 is simply running out of pixel throughput headroom. The 1080p Low figure of 217 FPS, which is more than three times the 4K Ultra result of 34 FPS, underscores how much resolution dictates the GPU's workload.

The Medium settings row provides the most granular data with min and max FPS values. At 1080p Medium, the average is 154 FPS with a range from 131 to 177 FPS. At 1440p Medium, that average drops to 97 FPS with a range of 83 to 112 FPS. Finally, at 4K Medium, the average falls to 51 FPS with a range of 43 to 58 FPS. The consistency of the frame times, as indicated by the relatively narrow min-max spread, suggests that the bottleneck is stable rather than spiky. The data indicates that the limiting component shifts from the CPU at 1080p to the GPU at 4K, with the crossover point occurring somewhere in the 1440p to 4K transition zone.

CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread processor based on the Raptor Lake architecture, and its benchmark scores are exceptionally strong. In Cinebench R23, it scores 30745 points in multicore and 2116 in singlecore. The PassMark multithread score is 45887, and the Geekbench multicore score is 19429. These numbers place the CPU in the 89th percentile of all CPUs, and it is remarkably close to its nearest rivals in average benchmark score, with the AMD Ryzen 9 5900 scoring 46971 against the i7-13700K's 46881, a delta of just -0.2%.

This CPU is not the constraint in Pc Building Simulator at 1080p. The 217 FPS result at 1080p Low is indicative of a system that is being held back by the graphics card, not the processor, because the CPU has ample headroom with 16 cores and a 5.40 GHz boost clock. The 3DMark max threads score of 12412 and the 3dmark 16 threads score of 10717 show that the CPU can handle massive parallel workloads, which is typical for a simulation game that needs to track many objects and calculations. However, the game's performance at 1080p, where the CPU is most likely to be the limiting factor, shows that the Arc B580 is the component that caps the frame rate. The fact that the 1080p Ultra result (103 FPS) is only slightly lower than the 1080p High result (109 FPS) suggests that the CPU is not being stressed by the higher settings, as the FPS difference is minimal.

The CPU's architecture, with 2 MB L2 cache per core and 30 MB shared L3 cache, provides fast access to game data. The data indicates that the i7-13700K's role is to ensure that the GPU is fed with enough data to avoid stutters, and its high single-thread performance (Cinebench R20 singlecore score of 2299) means that it can handle the main game thread efficiently. The benchmark results do not show any CPU-related frame drops, as the min FPS values are only present in Medium settings and are relatively close to the average FPS. This combo is not CPU-limited in a way that degrades the experience; rather, the CPU provides a stable platform that allows the GPU to be the primary determinant of frame rate at higher resolutions.

How This Combo Ranks

The combination of the Intel Core i7-13700K and the Intel Arc B580 ranks 2799 out of 3723 tested combos in Pc Building Simulator, placing it in the 25th percentile of all combinations. This is a low ranking that reflects the GPU's position in the market, not the CPU's. The Intel Arc B580 itself has a percentile rank of 68 among all GPUs, with an average benchmark score of 23021. Its nearest rivals in GPU performance are the AMD Radeon RX 580 2048SP (with a delta of -0.2%), the NVIDIA GeForce RTX 2080 (with a delta of 0.6%), and the NVIDIA GeForce RTX 3080 (with a delta of -0.7%). This places the B580 in a performance tier that is competitive with older high-end cards, but far from the top.

The combination's rank is dragged down by the GPU's relative weakness compared to the CPU's strength. The i7-13700K is a top-tier CPU that sits in the 89th percentile, but the B580's 68th percentile ranking means that the overall combo is not going to compete with systems that pair the same CPU with a more powerful GPU. The data shows that the combo rank is a function of the weakest link, and in this case, the GPU is the limiting factor for the overall score. The 4K Ultra result of 34 FPS is a clear indication that this combo is not designed for maximum graphical fidelity at high resolutions, but the 1440p Medium result of 97 FPS shows it is a competent performer for mainstream gaming.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings presets. At 1920x1080, the results are as follows: Low settings produce an average of 217 FPS, Medium settings produce 154 FPS with a range of 131 to 177 FPS, High settings produce 109 FPS, and Ultra settings produce 103 FPS. The gap between High and Ultra at 1080p is only 6 FPS, which is a negligible difference and suggests that the Ultra preset does not add a significant load to the system at this resolution.

Moving to 2560x1440, the average frame rates are 137 FPS for Low, 97 FPS for Medium (with a range of 83 to 112 FPS), 69 FPS for High, and 65 FPS for Ultra. The difference between High and Ultra narrows to just 4 FPS at 1440p, reinforcing the trend that the higher settings are not the primary driver of performance loss at this resolution. The data shows that the step from Medium to High at 1440p is a 28 FPS drop, which is the most significant settings-based delta at this resolution.

At 3840x2160, the performance drops significantly. Low settings yield 72 FPS, Medium settings yield 51 FPS (with a range of 43 to 58 FPS), High settings yield 36 FPS, and Ultra settings yield 34 FPS. The difference between High and Ultra at 4K is only 2 FPS, which indicates that the GPU is so heavily loaded that the additional settings have almost no impact. The 4K Low result of 72 FPS is a playable frame rate, but the 4K Ultra result of 34 FPS is not smooth for a fast-paced game, though this is a simulation title where lower frame rates may be more acceptable. The data consistently shows that the Ultra preset is not worth the performance cost at 4K, as it only provides a marginal visual improvement over High for a 2 FPS loss.

FAQ

Q: What is the best resolution to play at with this combo?

A: The data shows that 2560x1440 is the sweet spot. At Medium settings, it delivers an average of 97 FPS, which is smooth and well above the 60 FPS threshold.

At 4K, High is 36 FPS and Ultra is 34 FPS, a 2 FPS difference. The Ultra preset offers almost no performance benefit over High.

Q: Is the Core i7-13700K a strong CPU for this game?

A: Yes, the CPU is very strong, ranking in the 89th percentile of all CPUs. Its Cinebench R23 multicore score of 30745 and PassMark multithread score of 45887 indicate it can handle the simulation workload easily. The data shows no CPU-related bottlenecks, as the FPS is primarily limited by the GPU at all resolutions.

Settings Recommendations

The optimal settings preset for this combo depends on the target resolution and desired frame rate. For the best overall experience, the 2560x1440 Medium preset is the recommended choice. It delivers an average of 97 FPS with a minimum of 83 FPS, ensuring smooth gameplay without significant frame drops. The High preset at 1440p is also viable at 69 FPS, but the 28 FPS difference between Medium and High suggests that the visual upgrade is not worth the performance cost.

For users who prioritize frame rate over visual fidelity, the 1080p Low preset is the clear winner, providing 217 FPS. However, this is likely overkill for a simulation game, and the 1080p Medium preset at 154 FPS offers a better balance. At 4K, the Low preset is the only one that delivers a smooth experience at 72 FPS. The Medium preset at 4K is playable at 51 FPS, but the High and Ultra presets, at 36 and 34 FPS respectively, are too slow for a responsive experience. The data indicates that the Ultra preset should be avoided entirely, as it provides negligible visual gains over High at all resolutions, with the performance cost being only 2 to 6 FPS. Given the simulation genre, a stable 60 FPS is more valuable than marginal graphical improvements, so the Medium preset at 1440p or the Low preset at 4K are the most sensible choices for this hardware combination.
