# Pc Building Simulator: Intel Core i7-12700K + Intel Arc B370

This combination pairs a 12th-gen Intel desktop flagship-class CPU with a mobile-oriented integrated-class GPU, and the benchmark results reflect a system that is heavily GPU-bound in almost every scenario. The Intel Core i7-12700K is a 12-core, 20-thread Alder Lake-S part with a 3.60 GHz base clock and 5.00 GHz boost clock, while the Intel Arc B370 is a 3 nm Xe3-LPG integrated GPU with 1280 shading units, 40 TMUs, and 20 ROPs, boosting to 2400 MHz. The data shows a system that can handle Pc Building Simulator at 1080p with playable frame rates, but struggles at higher resolutions, making it a clear case of a CPU far outpacing its GPU partner.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B370 is an integrated GPU with System Shared memory, meaning it draws from the system's main memory rather than dedicated VRAM. Its base clock is 300 MHz with a boost of 2400 MHz, and it carries a 25 W TDP. The GPU's pixel rate is 48.00 GPixel/s and texture rate is 96.00 GTexel/s, with FP32 performance at 6.144 TFLOPS. In the 3DMark Steel Nomad DX12 benchmark, it scores 1184, placing it in the 5th percentile of all GPUs — a very low standing that signals entry-level integrated graphics performance.

The GPU's nearest rivals in the database are all older or lower-tier parts: the ATI Mobility Radeon HD 5570 (1186, delta -0.2%), ATI Radeon HD 5770 (1190, delta -0.5%), AMD Radeon HD 7650M (1192, delta -0.7%), and AMD FirePro M2000 (1168, delta +1.4%). All of these are within 1.4% of the Arc B370's score, confirming that this GPU sits at the bottom of the performance spectrum. For Pc Building Simulator, a game that involves navigating menus, viewing 3D models of components, and building PCs in a workshop environment, the GPU's limited fill rate and shared memory bandwidth become the primary constraints.

The boost clock of 2400 MHz is respectable for an integrated part, but the System Shared memory bandwidth is "System Dependent," which means performance scales with the platform's memory configuration. The GPU's 20 ROPs are a bottleneck for pixel throughput at high resolutions, explaining why 4K performance collapses. The DirectX 12 Ultimate support (12_2) and Vulkan 1.4 API compatibility are modern, but the underlying hardware is simply too weak to leverage these features meaningfully in this game.

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

The Intel Core i7-12700K is a formidable processor that provides far more compute headroom than the GPU can use in this game. With 12 cores and 20 threads across its Alder Lake-S architecture, it offers a base clock of 3.60 GHz and a boost clock of 5.00 GHz. The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 25 MB of shared L3 cache. Its benchmark scores are strong across the board: Cinebench R23 multicore hits 19784 and single-core 1850.5, while Geekbench multicore reaches 15790 and single-core 2308. The Passmark multithread score is 34404, with a single-thread score of 4013.

The CPU sits in the 84th percentile of all CPUs, with an average benchmark score of 35287. Its nearest rivals are the Intel Core i5-13600T (35305, delta -0.1%), Intel Core i7-12700KF (35365, delta -0.2%), Intel Core i7-13700T (35403, delta -0.3%), and Intel Core 5 213PE (35428, delta -0.4%). All of these are within 0.4% of the i7-12700K's score, indicating that it performs essentially identically to these alternatives. In the 3DMark multi-threaded tests, the CPU scores 9979 at max threads and 9276 at 16 threads, showing strong scaling with thread count.

For Pc Building Simulator, the CPU's role is to handle game logic, physics calculations for component interactions, and the simulation of power draw and temperatures. The 12-core/20-thread configuration is overkill for this title, but the single-thread performance (Cinebench R15 single-core 272, 3DMark single-thread 1043) is what matters most for the game's menu-driven interactions. The data indicates the CPU is never the limiting factor — even at 1080p Low, where the GPU is least stressed, the frame rate caps at 113 FPS, which is more likely a game engine limit than a CPU bottleneck.

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

At 1920x1080, the system delivers playable frame rates across all settings. Low settings average 113 FPS, Medium averages 80 FPS with a minimum of 68 and maximum of 92, High averages 56 FPS, and Ultra averages 54 FPS. The gap between Medium and High is 24 FPS, while the gap between High and Ultra is only 2 FPS, suggesting that Ultra's additional effects tax the GPU heavily without proportional visual benefit.

Moving to 2560x1440, performance drops significantly. Low settings average 71 FPS, Medium averages 50 FPS with a minimum of 43 and maximum of 58, High averages 36 FPS, and Ultra averages 34 FPS. The Medium preset at 1440p still maintains a playable frame rate, but High and Ultra fall below the 60 FPS threshold. The drop from 1080p to 1440p at Low settings is 42 FPS (from 113 to 71), a 37% reduction that clearly implicates the GPU's limited pixel throughput.

At 3840x2160, the system struggles to remain playable. Low settings average 37 FPS, Medium averages 26 FPS with a minimum of 22 and maximum of 30, High averages 19 FPS, and Ultra averages 18 FPS. Only the Low preset at 4K approaches playability, and even that falls short of 60 FPS. The minimum FPS of 22 at 4K Medium indicates stuttering, making the experience suboptimal for any serious gameplay. The data shows a clear trend: the Arc B370 is not designed for 4K gaming, and Pc Building Simulator's 3D component models become too demanding at this resolution.

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

The scaling behavior across resolutions reveals a classic GPU-bound scenario. From 1080p to 1440p, the average FPS at Low settings drops from 113 to 71, a 37% decrease. From 1440p to 4K, it drops further from 71 to 37, another 48% decrease. At High settings, the progression is 56 FPS at 1080p, 36 FPS at 1440p, and 19 FPS at 4K — each step roughly halves the frame rate. This near-linear scaling with pixel count (1080p has about 2.1 million pixels, 1440p about 3.7 million, 4K about 8.3 million) is the signature of a GPU that is completely saturated at every resolution.

The CPU's performance metrics suggest it could handle far more frames. With a Cinebench R23 multicore score of 19784 and a Passmark multithread score of 34404, the i7-12700K is capable of feeding a much faster discrete GPU. The fact that frame rates scale so closely with resolution changes — rather than plateauing due to CPU limits — confirms the GPU is the bottleneck. Even at 1080p Low, where the GPU has the least work, the 113 FPS average is likely near the game's engine cap or a reflection of the GPU's maximum throughput at that setting. The CPU's 84th percentile standing among all CPUs, compared to the GPU's 5th percentile, illustrates the massive performance disparity between these two components.

FAQ

Q: Is this combination playable at 1080p for Pc Building Simulator?

A: Yes, at 1080p Low the system averages 113 FPS, and at Medium it averages 80 FPS with a minimum of 68. High settings drop to 56 FPS, which is still above 30 FPS but below 60, while Ultra averages 54 FPS. For a simulation game where precise camera control matters, Medium at 1080p offers the best balance of smoothness and visual quality.

Q: Can this system handle 1440p gaming in Pc Building Simulator?

A: At 1440p, only Low settings (71 FPS) and Medium (50 FPS) are playable. High averages 36 FPS and Ultra averages 34 FPS, both below the 60 FPS threshold. If you have a 1440p monitor, sticking to Medium is recommended, as the minimum FPS of 43 at Medium is still acceptable for this genre.

Q: What about 4K performance?

A: The system cannot deliver a smooth 4K experience. Low settings average 37 FPS, Medium averages 26 FPS, High averages 19 FPS, and Ultra averages 18 FPS. Even the Low preset falls short of 60 FPS, and the Medium preset's minimum of 22 FPS would cause visible stuttering. This combination is not suitable for 4K gaming in this title.

Q: How does the Intel Arc B370 compare to its nearest rivals?

A: The Arc B370 scores 1184 in 3DMark Steel Nomad DX12, placing it in the 5th percentile of all GPUs. Its nearest rivals are the ATI Mobility Radeon HD 5570 (1186, -0.2%), ATI Radeon HD 5770 (1190, -0.5%), AMD Radeon HD 7650M (1192, -0.7%), and AMD FirePro M2000 (1168, +1.4%). All are within 1.4% of the Arc B370's performance.

Q: Is the Intel Core i7-12700K a strong CPU relative to other processors?

A: Yes, the i7-12700K sits in the 84th percentile of all CPUs with an average benchmark score of 35287. Its nearest rivals — the i5-13600T (35305, -0.1%), i7-12700KF (35365, -0.2%), i7-13700T (35403, -0.3%), and Core 5 213PE (35428, -0.4%) — are all within 0.4% of its score, indicating the i7-12700K is essentially tied with these parts.

Q: Why does the frame rate drop so much from 1080p to 4K?

A: The frame rate drops proportionally to the pixel count increase: from 113 FPS at 1080p Low to 71 FPS at 1440p Low to 37 FPS at 4K Low. This scaling pattern indicates the GPU is the limiting component, as the CPU's performance (Cinebench R23 multicore 19784) is far above the demands of this game at any resolution.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on your target resolution and acceptable frame rate floor. At 1080p, Medium settings provide the best experience: 80 FPS average with a minimum of 68 FPS, which ensures smooth gameplay even during complex build sequences. High settings at 1080p (56 FPS) are playable but noticeably less fluid, and Ultra (54 FPS) offers only marginal visual gains over High for a 2 FPS loss. The 24 FPS gap between Medium and High suggests that the GPU's limited texture and pixel throughput are heavily taxed by High's additional effects.

At 1440p, Medium is the highest playable preset, delivering 50 FPS average with a 43 FPS minimum. Low settings (71 FPS) provide the smoothest experience if you prioritize frame rate over visual fidelity. High (36 FPS) and Ultra (34 FPS) both fall below 40 FPS, which is likely to feel sluggish for camera movement and component manipulation. If you must play at 1440p, Medium is the recommended compromise — it keeps the minimum above 40 FPS while offering better textures and lighting than Low.

At 4K, the system should be set to Low (37 FPS) if you insist on this resolution, but the data indicates this is not a viable gaming setup. Medium at 4K (26 FPS average, 22 FPS minimum) will produce visible stutter, and High/Ultra (19/18 FPS) are effectively slideshows. For this combination, the practical ceiling is 1440p Medium or 1080p High, with 1080p Medium offering the most consistent performance across the entire benchmark suite. Given the GPU's 5th percentile ranking and the CPU's 84th percentile ranking, the i7-12700K has ample headroom for a future GPU upgrade, but as configured, this system is best suited for 1080p gaming with medium quality settings.
