Pc Building Simulator

The Intel Core i7-13700K paired with the AMD Radeon RX 7700 XT delivers a compelling experience in Pc Building Simulator, a simulation title that places distinctive demands on both processor and graphics card. The measured data shows a combination that scales predictably with resolution, with the GPU becoming the primary constraint at higher pixel counts while the CPU's strength is apparent at lower resolutions. This analysis breaks down the performance metrics to guide build decisions.

Resolution Scaling

The transition from 1080p to 4K reveals a classic GPU-bound shift. At 1080p with Low settings, the combo achieves 308.1 FPS, but this drops to 103.3 FPS at 4K Low — a 66.5% reduction. The scaling indicates that the RX 7700 XT is the limiting factor at 4K, as the CPU's headroom at lower resolutions is not fully utilized. At 1440p Low, the average is 192.2 FPS, which is 37.6% lower than the 1080p result, showing a steep decline as pixel count rises.

The pattern holds across all settings. With High settings, the average falls from 155.1 FPS at 1080p to 97.5 FPS at 1440p (a 37.1% drop) and then to 50.4 FPS at 4K (a 48.3% drop from 1440p). This consistent halving suggests that the GPU's pixel throughput is the bottleneck beyond 1440p, while the i7-13700K's 16 cores and 24 threads remain underutilized in this simulation. The game's simulation logic is not heavily threaded, so the CPU's high boost clock of 5.40 GHz is more relevant than its core count at 4K.

The gap between 1440p and 4K is particularly telling. At Medium settings, 1440p delivers 139 FPS while 4K drops to 69.9 FPS — a 49.7% reduction. This near-linear scaling with pixel count (2.25x more pixels at 4K) confirms that the RX 7700 XT's 12 GB GDDR6 memory and 432.0 GB/s bandwidth are the governing factors. The GPU's 2544 MHz boost clock helps at 1080p, but the 192-bit memory bus limits high-resolution performance.

How This Combo Ranks

In the database of tested combinations, this pairing ranks 758th out of 1769 combos for Pc Building Simulator, placing it in the 57th percentile of all tested systems. This mid-pack positioning reflects a balance: the CPU is in the 93rd percentile among all processors, but the GPU's 73rd percentile ranking drags the overall combo down. The data suggests that the i7-13700K is overqualified for this game at higher resolutions, where the GPU becomes the primary constraint.

Relative to its nearest rivals, the CPU's average benchmark score of 47282 is nearly identical to the Intel Core i7-13700KF (47334, deltaPct -0.1) and the AMD EPYC 4364P (47131, deltaPct 0.3). The i9-12900F trails by 0.4%, while the Ryzen 9 PRO 5945 leads by 0.5%. This tight clustering means the CPU choice has minimal impact on overall ranking, confirming that the GPU's role is more significant in this title. The combo's rank is likely influenced by the GPU's mid-tier standing, as systems with higher-end graphics cards would secure better positions.

GPU Role

The AMD Radeon RX 7700 XT, based on the Navi 32 chip with RDNA 3.0 architecture, provides 12 GB of GDDR6 memory on a 192-bit bus. Its 432.0 GB/s bandwidth is adequate for 1080p and 1440p but becomes a limiting factor at 4K. The GPU's 3456 shading units and 96 ROPs handle the game's visual effects, but the measured frame rates show that the 2544 MHz boost clock cannot compensate for the memory bandwidth deficit at higher resolutions.

The GPU's benchmark scores align with its 73rd percentile ranking. Its Passmark G3D score of 22547 and 3DMark Steel Nomad DX12 score of 3316 place it slightly below the NVIDIA GeForce RTX 5060 (deltaPct 0) and the Radeon RX 570 (deltaPct -0.2). The GPU's FP32 performance of 35.17 TFLOPS is substantial, but Pc Building Simulator does not appear to be compute-limited; instead, the data shows that the GPU's memory subsystem is the bottleneck at 4K.

The 12 GB VRAM is sufficient for this game at all tested settings, as no VRAM-related crashes or stutters are indicated by the data. The GPU's 245 W TDP and dual-slot design are typical for this class, but the measured FPS suggests that the card is best suited for 1440p gaming, where it delivers 97.5 FPS at High settings — a smooth experience. At 4K, the 50.4 FPS at High is playable but requires lower settings for consistent 60+ FPS.

Measured FPS Breakdown

The measured data provides a complete picture of performance across resolutions and settings. At 1080p, the combo excels: Low settings hit 308.1 FPS, Medium delivers 218.7 FPS, High reaches 155.1 FPS, and Ultra maintains 144.4 FPS. These numbers indicate that the CPU's 5.40 GHz boost clock is the primary driver, as the GPU has ample headroom at this resolution.

At 1440p, the averages are still strong but show the GPU's influence. Low settings produce 192.2 FPS, Medium drops to 139 FPS, High falls to 97.5 FPS, and Ultra settles at 93.1 FPS. The gap between High and Ultra is only 4.4 FPS, suggesting diminishing returns from the Ultra preset's extra effects. This 1440p performance is ideal for high-refresh-rate monitors, as even Ultra settings exceed 90 FPS.

At 4K, the GPU becomes the clear bottleneck. Low settings yield 103.3 FPS, Medium drops to 69.9 FPS, and both High and Ultra produce identical results: 50.4 FPS. The fact that High and Ultra have the same average FPS indicates that the GPU is fully saturated, and the Ultra preset's additional visual features do not affect performance because the card is already at its limit. This 4K performance is playable on a 60 Hz display but cannot maintain a stable 60 FPS at High or Ultra.

Settings Recommendations

For the best experience, 1440p with High settings is the sweet spot. The 97.5 FPS average is smooth, and the visual quality is high without the performance cost of Ultra. The 4.4 FPS difference between High and Ultra at 1440p does not justify the extra GPU load, so High offers the best balance of frame rate and fidelity.

At 1080p, Ultra settings are viable, with 144.4 FPS providing a great experience for high-refresh-rate displays. The 10.7 FPS gap between High and Ultra at this resolution is acceptable, so players prioritizing visuals can choose Ultra without concern. For competitive play, Low settings at 1080p deliver 308.1 FPS, which is far beyond any display's refresh rate and ensures minimal input lag.

At 4K, Medium settings are the recommended choice, as the 69.9 FPS average is closer to 60 FPS than High's 50.4 FPS. The 4K High and Ultra results are identical, indicating that the GPU is the limiter, so Medium provides the best playable experience without sacrificing too much visual quality. Low settings at 4K (103.3 FPS) are an option for those prioritizing frame rate over fidelity, but the visual downgrade is significant.

CPU Role

The Intel Core i7-13700K, with its 16 cores (8 performance and 8 efficient) and 24 threads, is a powerful processor that is largely underutilized in Pc Building Simulator. The game's simulation logic appears to be single-threaded or lightly threaded, as evidenced by the CPU's single-thread benchmark scores (1136 in 3DMark, 5505 in Cinebench R23) being more relevant than its multicore results (12412 in 3DMark max threads, 39000 in Cinebench R23).

The CPU's 5.40 GHz boost clock is the key factor in this game. At 1080p, the high clock speed allows the combo to reach 308.1 FPS on Low settings, demonstrating that the CPU is not a bottleneck at lower resolutions. The 3.40 GHz base clock is less relevant, as the processor boosts to its maximum under load. The 30 MB of L3 cache provides adequate bandwidth for the game's data, but the simulation's logic does not heavily utilize the 24 threads.

The CPU's ranking in the 93rd percentile of all processors confirms its strength, but this is overkill for Pc Building Simulator. The nearest rivals, including the i7-13700KF and EPYC 4364P, show negligible performance differences (deltaPct less than 0.5%), meaning a less expensive CPU could deliver similar results. The 125 W TDP is manageable, but the CPU's capability is not fully realized in this title, making the GPU the more critical component for improving performance.
