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

The AMD Ryzen 7 5800XT is an 8-core, 16-thread desktop processor built on the Zen 3 architecture (codename Vermeer) using TSMC's 7 nm process. It runs at a base clock of 3.80 GHz and boosts up to 4.80 GHz, with 64 KB of L1 cache per core, 512 KB of L2 per core, and a shared 32 MB L3 cache. The chip supports DDR4 memory in dual-channel configuration, yielding a memory bandwidth of 51.2 GB/s, and it connects via PCIe Gen 4 with 20 CPU lanes.

In Pc Building Simulator, a simulation title that emphasizes system assembly and management rather than intense real-time rendering, the CPU's thread count and boost behavior are central to the experience. The simulator must track numerous concurrent system states — component temperatures, power draws, case airflow, and user interactions — which benefits from the 16 threads available here. The 3dmark scores paint a clear picture: the CPU achieves 7,683 in the 16-thread test and 7,680 at max threads, indicating near-linear scaling across its physical cores. Single-thread performance is comparatively modest at 959 in 3dmark's single-thread test, but that's less critical for a game that spends most of its time managing background simulation logic rather than executing a single heavy thread.

Cinebench results reinforce the multi-threaded strength: the chip scores 23,794 in Cinebench R23 multi-core and 9,993 in R20 multi-core, while single-core scores are 3,359 and 1,410 respectively. The PassMark multithread score of 28,053 versus a single-thread score of 3,535 shows a roughly 8x multiplier, which is exactly what you'd expect from a well-fed 8-core/16-thread part. For a game like Pc Building Simulator, where the simulation tick rate and component interaction logic can leverage multiple cores, this CPU provides ample headroom.

The 5800XT sits at the 81st percentile among all CPUs in the benchmark database, with an average benchmark score of 29,879. Its nearest rivals in aggregate performance are the AMD Ryzen 7 7840H (avg score 29,868, delta 0%), the AMD Ryzen 7 8845HS and Ryzen 7 7840HS (both avg score 29,955, delta -0.3%), and the AMD Ryzen 5 9600X (avg score 29,713, delta 0.6%). The differences are negligible — within a fraction of a percent — meaning the 5800XT is essentially tied with these mobile and desktop parts in raw compute. This is notable because the 5800XT is a desktop chip with a 105 W TDP, yet it matches or slightly trails more power-efficient mobile processors in aggregate benchmarks, suggesting the game's CPU demands are well within its capabilities.

The 5800XT's release date of 2024-07-30 and launch MSRP of $249 position it as a late-life addition to the AM4 platform, with an unlocked multiplier for overclocking. For Pc Building Simulator specifically, the CPU's role is to keep the simulation fluid without becoming the bottleneck. Given that the game's measured FPS at 1080p Low reaches 113 FPS, the CPU is clearly not holding back the frame rate at lower settings — the limiting factor lies elsewhere, as examined in the GPU section.

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

The Intel Arc B370 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, built on Intel's 3 nm process. It operates at a base clock of 300 MHz and boosts to 2400 MHz, with 1,280 shading units, 40 texture mapping units, and 20 raster output units. The GPU includes 10 ray tracing cores and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Crucially, the Arc B370 has no dedicated VRAM — its memory is "System Shared," meaning it draws from the system's DDR4 memory pool. The memory bus width is also "System Shared," and bandwidth is "System Dependent," which ties GPU performance directly to the CPU's memory subsystem. In this configuration with the 5800XT's DDR4-3200 dual-channel setup (51.2 GB/s), the GPU's effective memory bandwidth is limited by that same 51.2 GB/s figure. This is a fundamental constraint: integrated GPUs rely on system memory bandwidth, and the 5800XT's DDR4 implementation, while adequate for CPU tasks, is far below what discrete GPUs offer.

The GPU's raw compute is modest: FP32 performance is 6.144 TFLOPS, with FP16 at 12.29 TFLOPS (2:1 ratio). The pixel rate is 48.00 GPixel/s, and the texture rate is 96.00 GTexel/s. In the only available benchmark, 3DMark Steel Nomad DX12, the Arc B370 scores 1,184 — placing it at the 5th percentile among all GPUs. Its nearest rivals are the ATI Mobility Radeon HD 5570 (score 1,186, delta -0.2%), ATI Radeon HD 5770 (score 1,190, delta -0.5%), AMD Radeon HD 7650M (score 1,192, delta -0.7%), and AMD FirePro M2000 (score 1,168, delta 1.4%). These are all legacy or low-end parts from over a decade ago, firmly establishing the Arc B370 as an entry-level graphics solution.

For Pc Building Simulator, the GPU's role is to render the 3D workshop environment, component models, and case interiors. The game is not graphically intensive by modern standards, but the Arc B370's integrated nature means it must share memory bandwidth with the CPU. The 25 W TDP and IGP form factor (slot width "IGP," no power connectors, portable device dependent display outputs) confirm this is designed for low-power systems, not gaming desktops.

The benchmark data shows the GPU's limitations clearly. At 1080p Low settings, the combo achieves 113 FPS, but this drops rapidly as resolution and settings increase. The GPU's 5th percentile ranking among all GPUs means it's outperformed by roughly 95% of the database's tested graphics solutions. In a game like Pc Building Simulator, where the simulation is CPU-heavy but the visual rendering still requires polygon throughput, the Arc B370 becomes the primary constraint at higher resolutions and quality presets.

# How This Combo Ranks

The combination of the AMD Ryzen 7 5800XT and Intel Arc B370 ranks 2,761 out of 3,002 tested combos in Pc Building Simulator, placing it in the bottom 8% of all configurations. This low ranking is driven almost entirely by the GPU, as the CPU is a strong performer while the GPU sits at the 5th percentile. The rank disparity highlights a severe imbalance: a top-tier CPU paired with a bottom-tier GPU.

To contextualize the CPU's contribution, the 5800XT's average benchmark score of 29,879 places it at the 81st percentile among CPUs. Its nearest rivals — the Ryzen 7 7840H, 8845HS, 7840HS, and 9600X — all score within 0.6% of the 5800XT, meaning the CPU is competitive with modern mid-range parts. The GPU, however, with an average score of 1,184, is at the 5th percentile and its nearest rivals are all over a decade old. The delta percentages among GPU rivals are all within 1.4%, indicating the Arc B370 is clustered with the absolute weakest GPUs in the database.

This ranking means that in Pc Building Simulator, the combo will struggle to maintain playable frame rates at higher settings, despite the CPU's ample compute headroom. The 2,761st rank out of 3,002 suggests that most other tested combos — even those with weaker CPUs — outperform this pairing because they include discrete GPUs. The data indicates that the game's performance is GPU-bound in nearly all scenarios, with the CPU's 16 threads unable to compensate for the integrated GPU's lack of dedicated memory bandwidth and low shading throughput.

# Measured FPS Breakdown

The measured FPS data covers three resolutions (1920x1080, 2560x1440, 3840x2160) and four settings presets (Low, Medium, High, Ultra). All data points are measured, not estimated.

1920x1080 (1080p):

• Low: 113 FPS average
• Medium: 80 FPS average (min 68, max 92)
• High: 56 FPS average
• Ultra: 54 FPS average

2560x1440 (1440p):

• Low: 71 FPS average
• Medium: 50 FPS average (min 43, max 58)
• High: 36 FPS average
• Ultra: 34 FPS average

3840x2160 (4K):

• Low: 37 FPS average
• Medium: 26 FPS average (min 22, max 30)
• High: 19 FPS average
• Ultra: 18 FPS average

At 1080p Low, the combo delivers a smooth 113 FPS, which is playable for a simulation title. Moving to Medium drops to 80 FPS, a 29% reduction, while High and Ultra hover around 54-56 FPS — a playable but not fluid experience. At 1440p, Low still hits 71 FPS, but Medium falls to 50 FPS and High/Ultra dip into the mid-30s, which is borderline for a game that requires precise clicking and system management. At 4K, the results are largely unplayable: only Low settings reach 37 FPS, while Medium, High, and Ultra all fall below 30 FPS, with Ultra at just 18 FPS.

The min/max FPS data for Medium settings shows consistent frame pacing: at 1080p, the range is 68-92 FPS (spread of 24), at 1440p it's 43-58 (spread of 15), and at 4K it's 22-30 (spread of 8). The narrowing range at higher resolutions indicates the GPU is becoming fully saturated, eliminating frame time variance because every frame is equally constrained by rendering throughput.

# Resolution Scaling

The FPS drop from 1080p to 4K reveals the limiting component clearly. At Low settings, the transition from 1080p (113 FPS) to 1440p (71 FPS) represents a 37% reduction, and from 1440p to 4K (37 FPS) a further 48% reduction — a total 67% drop from 1080p to 4K. At High settings, the progression is 56 FPS (1080p) → 36 FPS (1440p) → 19 FPS (4K), which is a 66% total drop. At Ultra settings, it's 54 → 34 → 18 FPS, a 67% drop.

These scaling patterns are characteristic of a GPU-bound scenario. If the CPU were the bottleneck, the FPS would remain relatively flat as resolution increases, because the CPU's workload (simulation logic) is resolution-independent. Instead, the FPS drops roughly proportionally to the pixel count increase: 1080p has ~2 million pixels, 1440p has ~3.7 million (1.85x), and 4K has ~8.3 million (4.15x). The measured drops — 37% from 1080p to 1440p and 67% from 1080p to 4K — approximate the pixel count scaling, confirming the Intel Arc B370 is the primary limiter.

The CPU's role in this scaling is minimal. The 5800XT's 16-thread performance, as shown by the 7,683 3dmark 16-thread score and 23,794 Cinebench R23 multi-core score, provides enough headroom to feed the GPU at all resolutions. Even at 4K Low (37 FPS), the CPU is likely idle waiting for the GPU to complete rendering. The fact that 1080p Low reaches 113 FPS — a frame rate that would require significant CPU work in many games — indicates the CPU can handle the simulation load without breaking a sweat.

The settings presets also tell a story. At 1080p, going from Low to Ultra costs 59 FPS (113 → 54), a 52% reduction. At 4K, the same settings change costs only 19 FPS (37 → 18), a 51% reduction. The consistent percentage drop across resolutions means the GPU's shading units and memory bandwidth are equally taxed regardless of resolution — it's simply overwhelmed at higher pixel counts.
