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

The Intel Core i5-12600KF is a 10-core, 16-thread processor based on the Alder Lake architecture, built on Intel's 10 nm process. It operates with a base clock of 3.70 GHz and a boost clock of 4.90 GHz, with a 125 W TDP and support for both DDR4 and DDR5 memory. This CPU is unlocked for overclocking, and its 20 MB of shared L3 cache helps feed the game's simulation workloads.

For Pc Building Simulator, a simulation title, the CPU's multi-threaded performance is highly relevant. The processor scores 23,444 in Cinebench R23 multi-core and 3,309 in single-core, indicating strong sustained throughput. In 3DMark, it reaches 7,956 in the 16-thread test and 7,952 in the max-thread test, showing that scaling from 16 threads to the full thread count yields minimal gains — the chip is already near its peak with 16 threads. The single-thread score of 1,016 in 3DMark and 3,925 in PassMark single-thread demonstrate solid per-core performance, which matters for game logic and physics in simulation titles.

The CPU's percentile ranking against all CPUs is 84, placing it in the upper tier. Its nearest rival, the Intel Core i9-10900K, has an identical average benchmark score of 27,829, with a deltaPct of 0. The i5-12600KF also sits within 0.1% of the Core i5-12600K (score 27,851) and 0.2% of the Core Ultra 5 125H (score 27,872), while edging the Core i7-13700H by 0.4% (score 27,716). This tight clustering means the CPU is not a bottleneck in this pairing — the measured FPS data confirms this, as even at 1080p Low with 368 FPS average, the frame rates are extremely high, suggesting the processor keeps up with the GPU's output.

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

The AMD Radeon RX 9070 XT is built on the RDNA 4.0 architecture using TSMC's 4 nm process, with a Navi 48 chip containing 53,900 million transistors on a 357 mm² die. It features 16 GB of GDDR6 memory on a 256-bit bus, delivering 644.6 GB/s of bandwidth. The GPU has a base clock of 1660 MHz, a boost clock of 2970 MHz, and a game clock of 2400 MHz, with memory running at 2518 MHz (20.1 Gbps effective).

For Pc Building Simulator, the GPU's raw rendering power is substantial. The card produces 48.66 TFLOPS of FP32 performance and has a pixel rate of 380.2 GPixel/s, along with 4096 shading units and 128 ROPs. In PassMark G3D, it scores 26,795, and in 3DMark Steel Nomad DX12, it reaches 7,260. The GPU's percentile ranking versus all GPUs is 82, placing it in the upper percentile.

The nearest rivals for the RX 9070 XT are somewhat surprising given its modern architecture. The AMD Radeon Pro 575 has an average score of 39,703 (deltaPct -0.1), the NVIDIA RTX A500 Mobile scores 39,568 (deltaPct 0.2), the Radeon Pro 575X scores 39,836 (deltaPct -0.5), and the Radeon RX Vega 64 scores 39,879 (deltaPct -0.6). These comparisons are based on average benchmark scores, and the RX 9070 XT's 39,647 average is effectively on par with these older or workstation-oriented parts in aggregate, though the game-specific FPS data shows the GPU is more than capable for this title.

# How This Combo Ranks

The combination of the Intel Core i5-12600KF and AMD Radeon RX 9070 XT ranks 406 out of 1,769 tested combos in Pc Building Simulator. This places it in the top 23% of all combinations tested, which is a strong showing for a mid-range-to-high-end pairing. The rank reflects the balanced nature of this setup — neither component is dramatically underpowered relative to the other, and the game's simulation focus means the CPU's 10 cores and the GPU's 16 GB of VRAM both contribute meaningfully.

Given that the data is measured (not estimated), this rank carries weight. The combo outperforms the vast majority of tested systems, with only 405 combinations achieving higher FPS across the tested resolutions and settings. The fact that the GPU sits at the 82nd percentile and the CPU at the 84th percentile among their respective categories suggests that this pairing extracts near-optimal performance from both components in this specific game.

# Measured FPS Breakdown

At 1920x1080, the i5-12600KF + RX 9070 XT delivers exceptional frame rates across all settings. Low settings produce an average of 368 FPS, Medium yields 261.7 FPS, High reaches 186.2 FPS, and Ultra drops to 171.6 FPS. These numbers indicate that even at Ultra, the system maintains well above 144 FPS, making it ideal for high-refresh-rate monitors.

Stepping up to 2560x1440, the frame rates remain very high. Low settings average 229.7 FPS, Medium hits 163.8 FPS, High achieves 114.4 FPS, and Ultra comes in at 113.1 FPS. The drop from High to Ultra at this resolution is minimal (only 1.3 FPS), suggesting that the Ultra preset's additional effects are not heavily taxing the GPU at 1440p.

At 3840x2160 (4K), the performance is still respectable but more demanding. Low settings average 123.1 FPS, Medium reaches 82.9 FPS, High drops to 62.5 FPS, and Ultra falls to 56.9 FPS. The 4K Ultra figure is just below the 60 FPS threshold, which could be a consideration for users with 4K displays seeking a locked 60 FPS experience.

# Resolution Scaling

The resolution scaling reveals a clear pattern: the performance drop from 1080p to 4K is substantial at every setting level, indicating that the GPU is the primary limiter at higher resolutions. At Low settings, the frame rate falls from 368 FPS at 1080p to 123.1 FPS at 4K — a 66.5% reduction. At Medium, the drop is from 261.7 FPS to 82.9 FPS, a 68.3% reduction. High settings fall from 186.2 FPS to 62.5 FPS (66.4% reduction), and Ultra falls from 171.6 FPS to 56.9 FPS (66.8% reduction).

The consistency of the percentage drop across all settings — roughly two-thirds — strongly suggests that the GPU's rendering throughput is the binding constraint as resolution increases. The CPU's performance headroom is evident in the 1080p Low result of 368 FPS, which is far beyond what the GPU can sustain at higher resolutions. If the CPU were the bottleneck, we would expect to see frame rates plateau or compress more at lower resolutions. Instead, the smooth scaling pattern points to the RX 9070 XT's bandwidth and compute limits driving the resolution-based FPS reduction.

# Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. At 1920x1080, the Ultra preset delivers an average of 171.6 FPS, which is more than sufficient for 144 Hz displays. There is no meaningful reason to drop below Ultra at this resolution, as even the most demanding preset maintains very high frame rates.

At 2560x1440, the High preset achieves 114.4 FPS, while Ultra reaches 113.1 FPS — a negligible difference of 1.3 FPS. Given the near-identical performance, the Ultra preset is the better choice at 1440p, as it provides the full visual experience without a meaningful FPS penalty. The 1440p Low preset at 229.7 FPS is only relevant for competitive play or maximizing frame rates on a 240 Hz display.

At 3840x2160, the High preset at 62.5 FPS is the best balance for a 60 Hz display, as it exceeds the refresh rate threshold. The Ultra preset at 56.9 FPS falls short of 60 FPS, making High the recommended setting for smooth 4K gameplay. For users with 120 Hz or higher 4K displays, the Medium preset at 82.9 FPS provides a substantial improvement over High while still maintaining high visual quality. The Low preset at 4K (123.1 FPS) is unnecessary for most users, as the visual compromise outweighs the FPS gain.
