# Pc Building Simulator with AMD Ryzen 9 8945HX + NVIDIA GeForce RTX 4070

This analysis examines the measured performance of the AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 4070 in Pc Building Simulator, based on benchmark data. The combination ranks 1577th out of 3002 tested combos in this game, placing it in the lower-middle portion of the field. The data reveals a system that handles the simulation genre comfortably at most settings, though 4K Ultra pushes the hardware to its limits. The following sections break down how resolution, settings, CPU, and GPU each contribute to the observed frame rates.

Resolution Scaling

The measured FPS data shows a clear and predictable scaling pattern as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average frame rate drops from 266 FPS at 1080p to 168 FPS at 1440p, then further to 88 FPS at 4K. This represents a 67% reduction from 1080p to 4K at Low settings, indicating that even at the lowest graphical preset, the resolution increase places substantial demand on the rendering pipeline.

At Medium settings, the scaling follows a similar trajectory: 189 FPS at 1080p, 119 FPS at 1440p, and 62 FPS at 4K. The 4K Medium result includes measured minimum and maximum values of 53 FPS and 72 FPS respectively, showing some variance but maintaining playable performance. The drop from 1440p to 4K at Medium is particularly steep — 119 FPS down to 62 FPS, a 48% reduction — which suggests that the pixel throughput required at 4K becomes the dominant limiting factor.

High settings exhibit the same pattern with 133 FPS at 1080p, 84 FPS at 1440p, and 44 FPS at 4K. Ultra settings produce 127 FPS at 1080p, 80 FPS at 1440p, and 42 FPS at 4K. The gap between High and Ultra at each resolution is relatively small (6 FPS at 1080p, 4 FPS at 1440p, and 2 FPS at 4K), indicating that Ultra adds minimal additional cost over High in this title.

The scaling data strongly suggests that at 1080p and 1440p, the CPU has headroom to feed the GPU, as frame rates remain high across all settings. At 4K, however, the render resolution becomes the bottleneck — the GPU's 12 GB of GDDR6X memory and its 504.2 GB/s bandwidth are taxed heavily when pushing 3840x2160 pixels. The fact that even Low settings at 4K only reaches 88 FPS, compared to 266 FPS at 1080p Low, demonstrates that resolution scaling is the primary performance determinant at 4K, while settings level plays a secondary role.

Settings Recommendations

The measured rows provide clear guidance on which preset offers the best balance of visual quality and performance. At 1920x1080, all four presets deliver playable frame rates: 266 FPS at Low, 189 FPS at Medium, 133 FPS at High, and 127 FPS at Ultra. The jump from Low to Medium costs 77 FPS (a 29% reduction), while the jump from Medium to High costs 56 FPS (a 30% reduction). The incremental cost from High to Ultra is only 6 FPS (a 5% reduction), making Ultra essentially free at 1080p.

At 2560x1440, the same pattern holds but with tighter margins. Low produces 168 FPS, Medium 119 FPS, High 84 FPS, and Ultra 80 FPS. The Medium setting includes a minimum of 101 FPS and maximum of 137 FPS, indicating stable performance. The difference between High and Ultra at 1440p is just 4 FPS, so choosing Ultra over High costs almost nothing in frame rate.

At 3840x2160, the situation changes dramatically. Low yields 88 FPS, Medium 62 FPS (with min/max of 53/72), High 44 FPS, and Ultra 42 FPS. While all these are technically playable, the 4K Ultra result of 42 FPS sits below the 60 FPS threshold that many users consider ideal. The 4K Medium result of 62 FPS, however, stays above that line while providing substantially better visual fidelity than Low.

For the best experience per the measured rows, 1440p Ultra stands out as the sweet spot. It delivers 80 FPS average, which is smooth for a simulation title, while the 4 FPS difference from High means no meaningful sacrifice is required to enable maximum settings. At 1080p, Ultra is similarly recommended since the 127 FPS result leaves ample headroom. At 4K, Medium is the pragmatic choice — it maintains an average above 60 FPS while the step to High drops to 44 FPS, a 29% reduction that is hard to justify for the visual gain.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor from the 8000 series, built on the Zen 4 architecture with a 5 nm process. Its base clock of 2.50 GHz and boost clock of 5.40 GHz, combined with 64 MB of L3 cache, provide substantial compute throughput. The CPU's benchmark scores reflect this capability: a Cinebench R23 multi-core score of 42713 and single-core score of 6030, with a Passmark multi-thread score of 51405.

In Pc Building Simulator, a simulation genre title, CPU performance typically matters for game logic, physics calculations, and asset management. The data shows that at 1080p, the frame rates scale more with settings than with resolution, which suggests the CPU is not the primary limiter at this resolution. The 266 FPS result at 1080p Low indicates the processor can feed the GPU well beyond typical display refresh rates.

The CPU's nearest rivals in aggregate benchmark scores include the Intel Core Ultra 9 285HX with a delta of 0.1% (essentially tied), the AMD EPYC Embedded 8224P at -0.4%, and the AMD Ryzen Threadripper PRO 9945WX at -0.4%. The Ryzen 9 9950X3D sits 0.6% higher. These margins are negligible, meaning the 8945HX performs on par with top-tier alternatives in general compute tasks.

The 32 threads and high boost clock of 5.40 GHz are particularly relevant for simulation games, which often benefit from parallel processing for game state updates. The Passmark physics score of 2168 and data compression score of 677755 indicate strong integer and floating-point throughput. However, the measured FPS data shows that even at 4K Low (88 FPS), the CPU maintains high frame delivery, so the processor is unlikely to bottleneck this game at any tested setting.

FAQ

A: The only settings with recorded minimum FPS values are Medium presets. At 4K Medium, the minimum is 53 FPS; at 1440p Medium, it is 101 FPS; at 1080p Medium, it is 160 FPS. These minimums indicate stable frame delivery without severe drops.

GPU Role

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture with 5888 shading units, 184 texture mapping units, and 64 render output units. It features 46 ray tracing cores and 184 tensor cores, with a boost clock of 2475 MHz. The GPU's 12 GB of GDDR6X memory runs at an effective 21 Gbps across a 192-bit bus, yielding 504.2 GB/s of bandwidth. The card consumes 200 W TDP and requires a 550 W suggested PSU.

In Pc Building Simulator, the GPU's role is primarily rendering the simulation's interface, 3D components, and system visualization. The measured FPS data shows the GPU handling all tested settings without falling below playable thresholds, except potentially at 4K Ultra where 42 FPS is marginal. The 3DMark Steel Nomad DX12 score of 3854 and Passmark G3D score of 26927 place the GPU in the 81st percentile of all GPUs, indicating solid mid-to-high-end performance.

The RTX 4070's nearest rivals in aggregate score are closely matched: the NVIDIA Tesla P4 is 0.1% higher, the AMD Radeon RX Vega 56 is 0.4% higher, and the AMD Radeon PRO W6400 is 1.3% higher, while the NVIDIA GeForce RTX 4080 Mobile is 1.3% lower. These small deltas suggest the 4070 performs within a narrow band of its peers, making the specific choice less critical for this game.

The GPU's 12 GB VRAM is sufficient for the settings tested, as evidenced by the consistent frame rates without indication of texture swapping or memory-related stutters. The 504.2 GB/s bandwidth supports the 4K Medium result of 62 FPS, but the drop to 44 FPS at 4K High suggests the GPU's compute capacity, not memory, is the limiting factor at higher presets. The FP32 throughput of 29.15 TFLOPS provides ample headroom for a simulation title that likely does not heavily utilize ray tracing or tensor operations.

Measured FPS Breakdown

The complete measured FPS dataset for this combo covers three resolutions and four settings levels, providing a comprehensive view of performance. At 1920x1080, the results are: Low 266 FPS, Medium 189 FPS (min 160, max 217), High 133 FPS, and Ultra 127 FPS. These numbers show that even at the highest preset, the system delivers well above 60 FPS, making 1080p a resolution where users can max out settings without concern.

At 2560x1440, the results drop but remain strong: Low 168 FPS, Medium 119 FPS (min 101, max 137), High 84 FPS, and Ultra 80 FPS. The Medium preset's minimum of 101 FPS is particularly notable, as it shows the system maintains high frame delivery even during demanding scenes. The 4 FPS gap between High and Ultra at this resolution suggests Ultra is a free upgrade.

At 3840x2160, the results become more constrained: Low 88 FPS, Medium 62 FPS (min 53, max 72), High 44 FPS, and Ultra 42 FPS. The 4K Medium result is the only 4K preset that averages above 60 FPS, while 4K High and Ultra fall into the 40-45 FPS range, which is playable but not ideal for fast-paced interaction. The minimum FPS of 53 at 4K Medium shows occasional dips below 60, but the average remains acceptable.

The pattern across resolutions is consistent: each doubling of pixel count (from 1080p to 1440p is a 78% increase, from 1440p to 4K is a 125% increase) results in roughly proportional FPS decreases. The data shows no anomalies or unexpected bottlenecks, indicating a well-balanced system where GPU rendering scales predictably with resolution and settings.

How This Combo Ranks

The AMD Ryzen 9 8945HX + NVIDIA GeForce RTX 4070 combination ranks 1577th out of 3002 tested combos in Pc Building Simulator, placing it in the 47.5th percentile of all configurations. This mid-pack ranking is somewhat surprising given the individual components' strong benchmark scores — the CPU ranks in the 95th percentile of all CPUs, and the GPU ranks in the 81st percentile of all GPUs.

The discrepancy between component-level and combo-level rankings suggests that Pc Building Simulator may not fully utilize the hardware's capabilities, or that the game's performance is constrained by factors other than raw compute power. The measured FPS data supports this interpretation: even at 4K Ultra, the system achieves 42 FPS, which is respectable for a simulation title that likely has less demanding graphics than AAA action games.

The combo's ranking in the lower-middle of the pack does not indicate poor performance — rather, it reflects the wide range of hardware configurations tested. The CPU's nearest rivals (Intel Core Ultra 9 285HX, AMD EPYC Embedded 8224P, AMD Ryzen Threadripper PRO 9945WX, AMD Ryzen 9 9950X3D) are all within 0.6% in aggregate score, meaning the CPU is competitive with top-tier options. The GPU's rivals are similarly close, with deltas under 1.3%.

For a simulation game that emphasizes system building and management rather than high-octane rendering, this combo delivers adequate performance across all tested settings. The 1440p Ultra result of 80 FPS is particularly strong, and the 1080p results exceed 127 FPS at every preset. Users seeking maximum visual quality at 4K will need to accept 42-44 FPS at High/Ultra, but the Medium preset offers a playable 62 FPS. The ranking data confirms that while this combo is not at the top of the charts, it provides a competent experience for the game's intended gameplay.
