# Pc Building Simulator — AMD Ryzen 9 7900X + NVIDIA GeForce GTX 1070

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce GTX 1070 produces a curious split in Pc Building Simulator: the CPU sits in the 93rd percentile among all processors, while the GPU lands at the 51st percentile, and the measured frame rates across resolutions and settings reveal a system that is almost entirely constrained by the graphics card. This 12-core, 24-thread Zen 4 processor with a 4.70 GHz base and 5.60 GHz boost clock has ample headroom, but the Pascal-based GTX 1070 with its 8 GB of GDDR5 memory and 1506 MHz base clock becomes the decisive factor in every meaningful scenario.

Resolution Scaling

The data shows a steep and predictable drop in average FPS as resolution increases, but the shape of that drop changes depending on the quality preset. At Low settings, the system delivers 182.9 FPS at 1920x1080, 113.7 FPS at 2560x1440, and 64 FPS at 3840x2160. That represents a 37.8% reduction from 1080p to 1440p, and a 43.7% further reduction moving to 4K. Low settings at 4K still produce a playable 64 FPS, indicating the GTX 1070 can handle the pixel throughput when shading complexity is minimized.

At High settings, the scaling is less forgiving: 90.4 FPS at 1080p, 57.6 FPS at 1440p, and 29 FPS at 4K. The 4K result falls below the 30 FPS threshold commonly considered the minimum for smooth gameplay, and the drop from 1440p to 4K is a 49.7% loss. Medium settings follow a similar pattern: 131.8 FPS at 1080p, 81.7 FPS at 1440p, and 45.3 FPS at 4K. Ultra settings produce the steepest cliff — 90.3 FPS at 1080p, 56 FPS at 1440p, and 26.7 FPS at 4K — with the gap between High and Ultra at 1080p being negligible (90.4 vs. 90.3 FPS).

The limiting component becomes clear when comparing Low and Ultra at the same resolution. At 1080p, Low yields 182.9 FPS while Ultra yields 90.3 FPS, a 102.6% difference. At 4K, the same comparison shows 64 FPS versus 26.7 FPS, a 139.7% difference. This widening gap at higher resolutions indicates the GPU is the bottleneck; the Ryzen 9 7900X is not the constraint, as its single-thread and multi-thread performance (Cinebench R23 scores of 6168 and 43695, respectively) far exceed what this workload requires.

GPU Role

The GTX 1070's specifications explain the resolution sensitivity. With 8 GB of GDDR5 memory on a 256-bit bus, the card delivers 256.3 GB/s of bandwidth — sufficient for 1080p and even 1440p in this simulation title, but strained at 4K. The 1506 MHz base clock and 1683 MHz boost clock, combined with 1920 shading units and 64 ROPs, produce a pixel rate of 107.7 GPixel/s and a texture rate of 202.0 GTexel/s. These figures are adequate for the modest geometry of Pc Building Simulator, but the card's 6.463 TFLOPS FP32 throughput limits how many pixels can be shaded per frame at high resolutions.

The VRAM capacity is the more pressing concern. At 4K Ultra, the system averages 26.7 FPS, and the 8 GB frame buffer likely saturates with the combination of high-resolution textures and anti-aliasing typical of Ultra presets. The 3DMark Steel Nomad DX12 score of 1082 and PassMark G3D score of 13498 place this GPU at the 51st percentile, and its nearest rivals — the NVIDIA Quadro K4200 (0.7% higher), GeForce GTX 880M (1.3% lower), and GeForce GTX 1650 SUPER (1.4% lower) — all sit within a narrow band. This confirms the GTX 1070 is a mid-pack component in 2025, and its age (released 2016-06-09, now end-of-life) shows in the 4K results.

Interestingly, the GPU's memory clock of 2002 MHz (8 Gbps effective) does not appear to be a limiting factor at 1080p, where even Ultra settings achieve 90.3 FPS. The bottleneck emerges only when pixel count rises, and the card's 16 nm process node and 150 W TDP suggest it was designed for a different era of gaming resolution expectations.

How This Combo Ranks

The combination ranks 1498 out of 1769 tested combos in Pc Building Simulator, placing it in the bottom 15.3% of all CPU-GPU pairings. This low ranking is primarily attributable to the GPU, not the CPU. The Ryzen 9 7900X, with an average benchmark score of 50556, sits within 0.8% of its nearest rivals (Intel Core Ultra 5 235 at -0.1%, AMD Ryzen 9 5900XT at -0.4%, Intel Core i7-13850HX at -0.5%, Intel Core i9-13980HX at -0.8%). The GTX 1070, by contrast, has an average benchmark score of 12331, nearly identical to its rivals but far below modern GPUs.

The mismatch is stark: the CPU's 12 cores and 24 threads provide 83.2 GB/s of memory bandwidth and support DDR5, PCIe Gen 5, and 24 CPU lanes, yet the GPU communicates over PCIe 3.0 x16. This pairing bottlenecks the CPU's potential in gaming scenarios. In Pc Building Simulator specifically, the game's simulation-heavy mechanics — managing PC builds, running benchmarks, and navigating menus — may leverage CPU threads, but the actual rendering workload is GPU-bound. The result is a system that performs respectably at 1080p (90.4 FPS on High) but falls apart at 4K (29 FPS on High).

The combo's rank of 1498 suggests that most other tested combinations deliver better overall performance in this game. The data implies that a more balanced pairing — one where the GPU's percentile more closely matches the CPU's — would yield higher frame rates across the board. The 7900X's 93rd percentile CPU standing is wasted when paired with a 51st percentile GPU, as the measured FPS never approaches what the CPU could theoretically support at 1080p.

Settings Recommendations

Based on the measured rows, the optimal balance of visual quality and frame rate comes at Medium settings with 1920x1080, where the system averages 131.8 FPS. This is 45.8% higher than High settings at the same resolution (90.4 FPS) and only 15.4% lower than Low settings (182.9 FPS). The jump from Medium to High costs 41.4 FPS, a significant penalty for marginal visual gains in a simulation game where readability of system components matters more than elaborate effects.

For users with 1440p displays, Medium settings at 2560x1440 deliver 81.7 FPS, which is smooth and only 17.6% lower than the 1080p Medium result. High settings at 1440p drop to 57.6 FPS, still playable but with less headroom for frame-time spikes. At 4K, the only viable option is Low settings, which yields 64 FPS; Medium drops to 45.3 FPS, and both High (29 FPS) and Ultra (26.7 FPS) fall below acceptable thresholds.

Ultra settings offer no measurable benefit over High at 1080p — the difference is 0.1 FPS (90.3 vs. 90.4) — so there is no reason to select Ultra at any resolution given the performance cost. The recommendation is clear: for a locked 60+ FPS experience, use Medium at 1080p or 1440p; for 4K, accept Low settings or lower the resolution. The data does not support any configuration above Medium for consistent performance, as the GTX 1070's VRAM and shading capabilities are the binding constraint.

FAQ

Q: Can this combo run Pc Building Simulator at 4K smoothly?

A: Only at Low settings, where it averages 64 FPS. Medium settings drop to 45.3 FPS, High to 29 FPS, and Ultra to 26.7 FPS — the latter two are below the 30 FPS threshold for smooth gameplay.

Q: What is the best resolution for this system?

A: 1920x1080 is the strongest, with all settings producing at least 90.3 FPS. At 2560x1440, only Low and Medium exceed 60 FPS (113.7 and 81.7 FPS, respectively); High and Ultra average 57.6 and 56 FPS.

Q: Is the Ryzen 9 7900X or GTX 1070 the bottleneck?

A: The GPU is the limiting component. The CPU ranks in the 93rd percentile, while the GPU sits at the 51st percentile. The FPS scaling with resolution and settings — a 139.7% difference between Low and Ultra at 4K — indicates the graphics card is the constraint.

Q: How does this combo rank among all tested configurations?

A: It ranks 1498 out of 1769 combos, placing it in the bottom 15.3% of all CPU-GPU pairings tested in Pc Building Simulator.

Q: What settings provide the best experience?

A: Medium at 1920x1080 (131.8 FPS) offers the best combination of visual quality and performance. High at 1080p (90.4 FPS) is also viable, but Ultra provides no benefit over High (90.3 vs. 90.4 FPS).

Q: Does the GTX 1070's 8 GB VRAM cause issues?

A: At 4K Ultra, the system averages 26.7 FPS, suggesting VRAM capacity is strained at high resolutions. At 1080p, the 8 GB frame buffer is sufficient, as even Ultra achieves 90.3 FPS. The card's 256.3 GB/s bandwidth and 6.463 TFLOPS FP32 throughput are the more fundamental limits at higher resolutions.
