Pc Building Simulator

The Intel Core i5-12600KF and Intel Arc B580 pairing in Pc Building Simulator delivers a performance profile that is heavily dictated by the graphics card, with CPU headroom that allows the GPU to stretch its legs at higher resolutions. The i5-12600KF is a 10-core, 16-thread Alder Lake-S desktop processor with a base clock of 3.70 GHz and a boost clock of 4.90 GHz, built on Intel's 10 nm process. Its 20 MB of shared L3 cache and support for both DDR4 and DDR5 memory make it a versatile foundation, but in this simulation title, the data shows the Arc B580 is the primary bottleneck. The GPU, based on the Xe2-HPG architecture (Battlemage), offers 12 GB of GDDR6 memory on a 192-bit bus with 456.0 GB/s of bandwidth, which proves sufficient for the game's demands, though the processor's single-thread performance—a 3dmark_single_thread score of 1016 and a Cinebench R23 single-core score of 3309—ensures it never holds the frame rate back.

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

The i5-12600KF's 10 cores and 16 threads are far more than Pc Building Simulator needs to feed the Arc B580. Benchmark results show the CPU's multithreaded strength, with a Cinebench R23 multicore score of 23444 and a Geekbench multicore score of 12373, placing it in the 84th percentile of all CPUs. Its nearest rival, the Intel Core i9-10900K, scores an average of 27829, a deltaPct of 0, meaning the two are effectively tied in synthetic loads. The i5-12600K is also within 0.1% (average score 27851), confirming that the unlocked "KF" variant trades nothing in raw compute. In game, this translates to a processor that can easily handle the simulation's logic, asset loading, and any background threads without becoming a limiting factor.

The boost clock of 4.90 GHz is the key figure here. Single-threaded performance, as measured by the 3dmark_2_threads score of 1995 and the Passmark single-thread score of 3925, is strong enough that at 1080p Low settings, where the GPU is less stressed, the CPU still delivers a 217.8 FPS average. Compare that to the 4K Ultra result of 34.8 FPS—the gap is entirely GPU-bound. The CPU's 125 W TDP and Intel Socket 1700 compatibility make it a standard choice, but the data indicates that even a weaker processor would likely produce similar frame rates in this title, as the Arc B580's 13.67 TFLOPS FP32 performance and 213.6 GPixel/s pixel rate become the ceiling. The processor's role here is to provide stable frame pacing, which it does admirably, given the consistent FPS numbers across all settings.

FAQ — 4-6 Q&A pairs answerable from FACT PACK data

Q: How does the i5-12600KF compare to the Intel Core i9-10900K in synthetic benchmarks?

A: The two are statistically identical. The i9-10900K has an average benchmark score of 27829, while the i5-12600KF averages 27827, a deltaPct of 0. This means in CPU-bound scenarios, you would not notice a difference between them.

Q: What is the best settings preset for 1080p gaming with this combo?

A: At 1920x1080, the High preset delivers 108 FPS average, which is smooth for most players. However, the Medium preset offers a 153.4 FPS average, a 42% improvement over High, and is the best balance for high refresh rate monitors. Ultra drops to 99.7 FPS, which is still playable but offers diminishing returns.

Q: Is the Arc B580's 12 GB VRAM sufficient for 4K gaming in this simulator?

A: Yes, but with caveats. At 3840x2160, the Ultra preset achieves 34.8 FPS, which is below the 60 FPS threshold. Dropping to Low yields 72 FPS, showing the VRAM is not the issue—the GPU's compute power is the limiting factor. The memory bandwidth of 456.0 GB/s is enough, but the card's 13.67 TFLOPS FP32 is not.

Q: How does the combo rank among all tested configurations?

A: This CPU-GPU combination ranks 1384 out of 1769 total tested combos in Pc Building Simulator. This places it in the lower-middle tier, reflecting the Arc B580's mid-range status rather than the CPU's capability, as the i5-12600KF is in the 84th percentile of all CPUs.

Q: What is the frame rate drop from 1080p to 4K at High settings?

A: At High settings, the average FPS goes from 108 at 1080p to 69.6 at 1440p, then down to 34.5 at 4K. This represents a 68% reduction from 1080p to 4K, confirming that the GPU is the primary performance limiter, as the CPU would not scale this poorly.

Q: How does the Arc B580 compare to the NVIDIA GeForce RTX 4060 in raw GPU benchmarks?

A: The average benchmark score for the Arc B580 is 23021, while the RTX 4060 scores 23181, a deltaPct of -0.7% for the Arc B580 (meaning it is 0.7% slower). In practical terms, this is negligible, and the two cards should perform nearly identically in most games.

Settings Recommendations — which preset gives the best experience per the measured rows

For 1080p, the Medium preset is the clear winner. At 153.4 FPS average, it is 42% faster than High (108 FPS) and 54% faster than Ultra (99.7 FPS), while still looking noticeably better than Low (217.8 FPS, which is overkill for most displays). The jump from Low to Medium costs 64.4 FPS but provides a substantial visual upgrade, making Medium the sweet spot for smooth gameplay. If you have a 144Hz monitor, Ultra at 99.7 FPS is still above the 60 FPS minimum, but Medium ensures you stay well above refresh rate thresholds.

At 1440p, the same logic applies. Medium delivers 93.5 FPS, which is close to 100 FPS and ideal for high-refresh displays. High drops to 69.6 FPS, which is still playable but not as fluid, while Ultra falls to 64.2 FPS. For 4K gaming, the choice is starker. Low settings are the only way to achieve a playable experience, with 72 FPS average. Medium at 51.5 FPS is borderline, and High (34.5 FPS) and Ultra (34.8 FPS) are not recommended for anything but screenshots. The data suggests that this combo is best suited for 1080p Medium or 1440p Medium, where the Arc B580's 12 GB VRAM and 192-bit memory bus are fully utilized without exceeding the GPU's compute limits.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combo's rank of 1384 out of 1769 tested configurations places it in the bottom 22% of all CPU-GPU pairings tested in Pc Building Simulator. This is a poor showing, but the reasoning is clear when you look at the components. The i5-12600KF is a high-end CPU (84th percentile), but the Arc B580 is only in the 66th percentile of all GPUs, and its average benchmark score of 23021 is nearly identical to the integrated AMD Radeon 760M (22999, deltaPct 0.1%). This means the GPU is the anchor dragging the combo down. The CPU's nearest rivals—the i9-10900K, i5-12600K, and Core Ultra 5 125H—all have average scores within 0.4% of the i5-12600KF, so swapping the CPU would not change the ranking.

What this rank means practically is that many cheaper CPU and GPU combinations will outperform this pairing in this specific simulation title. The Arc B580's 66th percentile ranking is respectable for a mid-range card, but it is not competitive with the top-tier GPUs that dominate the upper ranks. The card's Passmark G3D score of 15748 and DirectX 12 score of 76 indicate solid DirectX 12 performance, but Pc Building Simulator is not a graphically intensive title, so the GPU's raw compute is less important than its memory bandwidth and fill rate. The 213.6 GPixel/s pixel rate and 427.2 GTexel/s texture rate are adequate, but they do not push the combo into the upper echelons of the rankings.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS scaling from 1080p to 4K is a textbook example of GPU-bound behavior. At High settings, the average FPS drops from 108 at 1920x1080 to 69.6 at 2560x1440 (a 35.6% reduction), then to 34.5 at 3840x2160 (another 50.4% reduction from 1440p). This is a total drop of 68% from 1080p to 4K, which is far steeper than what a CPU-bound scenario would produce. If the CPU were the limiter, you would expect the FPS to stay relatively flat across resolutions, as the processor's workload does not change with resolution. Instead, the data shows a clear linear trend that tracks with the pixel count.

The same pattern appears at Medium settings: 153.4 FPS at 1080p, 93.5 FPS at 1440p (39% drop), and 51.5 FPS at 4K (45% drop from 1440p). Low settings show 217.8 FPS at 1080p, 135.8 FPS at 1440p, and 72 FPS at 4K. The consistent halving of frame rates at each resolution step confirms the Arc B580 is the bottleneck. The CPU's 10 cores and 16 threads are never stressed to their limits, even at 1080p Low where the frame rate is highest. This means that if you were to upgrade the GPU, you would see significant FPS gains at all resolutions, but upgrading the CPU would yield almost no improvement in this game.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the data shows a wide range of performance depending on settings. Low settings produce an average of 217.8 FPS, which is the highest recorded for this combo. Medium drops to 153.4 FPS, a 29.5% reduction from Low. High further reduces to 108 FPS, and Ultra bottoms out at 99.7 FPS. The gap between High and Ultra is only 8.3 FPS, suggesting that Ultra adds visual effects that are not worth the performance cost on this GPU.

Moving to 2560x1440, the numbers scale down proportionally. Low settings yield 135.8 FPS, which is still above 120 FPS and suitable for high-refresh gaming. Medium follows at 93.5 FPS, High at 69.6 FPS, and Ultra at 64.2 FPS. The difference between High and Ultra narrows to 5.4 FPS, making High the more sensible choice for 1440p if you want to stay above 60 FPS without sacrificing too much quality.

At 3840x2160, the GPU's limits become apparent. Low settings still manage 72 FPS, which is playable, but Medium drops to 51.5 FPS, and High falls to 34.5 FPS. Ultra is marginally better than High at 34.8 FPS, which is within the margin of error and suggests that Ultra and High are equally demanding on this GPU. For 4K, Low is the only setting that delivers a consistently smooth experience, and even then, the 72 FPS average is only just above the 60 FPS threshold. The data clearly indicates that this combo is optimized for 1080p and 1440p gaming, with 4K being a stretch that requires significant setting compromises.
