CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture (Phoenix codename), built on TSMC's 4nm process node. It operates at a base clock of 4.20 GHz and boosts up to 4.70 GHz, with a 65W TDP. The CPU's 16 MB shared L3 cache and 1 MB L2 cache per core provide the memory hierarchy needed for the simulation-heavy workloads of Pc Building Simulator.

Benchmark data indicates the CPU is a solid mid-range performer. Its Cinebench R23 multi-core score of 20851 places it in the 82nd percentile among all CPUs, while the single-core score of 2943 is respectable for Zen 4. The 3DMark results show strong scaling from 2 threads (1874) to max threads (6165), suggesting the 12-thread configuration is well-utilized in threaded workloads. The PassMark multithread score of 24530 reinforces this, though the single-thread score of 3684 shows the CPU's per-core strength.

In Pc Building Simulator, the CPU's role is significant because the game simulates component interactions, boot sequences, and system performance calculations. The 8400F's 12 threads handle these calculations efficiently, but the game's demands are not extreme. The data shows that at 1080p Low settings, the combo achieves 183.7 FPS, which is well above playable thresholds. However, the CPU's 82nd percentile ranking suggests it is not a bottleneck at lower resolutions — the GPU becomes the limiting factor as resolution increases.

The nearest rival comparison shows the 8400F is effectively tied with the older Ryzen 7 2700X (25057 avg score, 0% delta) and the newer Ryzen 5 7500F (24993, 0.3% ahead). This indicates the CPU is competitively positioned within its performance class, though the Zen 4 architecture's efficiency advantage (4nm vs older nodes) does not translate into a large gaming advantage in this simulation title.

GPU Role

The NVIDIA GeForce GTX 1070 is a Pascal-architecture GPU (chip GP104) built on TSMC's 16nm process, featuring 1920 shading units, 120 texture units, and 64 ROPs. It operates at a base clock of 1506 MHz with a boost of 1683 MHz, paired with 8 GB of GDDR5 memory on a 256-bit bus delivering 256.3 GB/s bandwidth. The GPU's 6.463 TFLOPS of FP32 performance and 107.7 GPixel/s pixel rate are modest by modern standards, which is reflected in its 51st percentile ranking among all GPUs.

The GTX 1070's average benchmark score of 12331 places it near the middle of the GPU performance spectrum. Its closest rivals include the Quadro K4200 (12241, 0.7% behind) and the GTX 1650 SUPER (12504, 1.4% ahead). The GPU's DirectX 12 score in PassMark is 48, which is notably lower than its DirectX 11 score of 100, suggesting the Pascal architecture does not excel in modern API workloads. This is relevant for Pc Building Simulator, which uses DirectX 12.

In terms of gaming performance, the GTX 1070 is the dominant factor in this combo's results. At 1080p High settings, the combo achieves 94.1 FPS, but this drops to 55.4 FPS at 1440p and 27.9 FPS at 4K. The GPU's 8 GB VRAM is sufficient for this simulation game, which does not require massive texture memory. However, the GPU's age (released in 2016 and now end-of-life) means it struggles at higher resolutions, particularly at Ultra settings where 4K performance falls to 28.9 FPS.

How This Combo Ranks

The AMD Ryzen 5 8400F + GTX 1070 combination ranks 1499 out of 1769 tested combos in Pc Building Simulator, placing it in the bottom 15% of all configurations. This low ranking is primarily due to the GPU's age and mid-tier performance, as the CPU alone ranks in the 82nd percentile. The data shows that this combo is not optimized for high-resolution gaming, with 4K Ultra performance at 28.9 FPS being barely playable.

Relative to other combos, this pairing represents a mismatch: the CPU is a modern, efficient Zen 4 processor while the GPU is a Pascal-era mid-range card. In the benchmark database, combos with newer GPUs paired with this CPU would likely rank significantly higher. The 1499th rank out of 1769 indicates that most tested configurations outperform this one, despite the CPU's strong showing in synthetic benchmarks.

The combo's performance profile suggests it is best suited for 1080p gaming, where it achieves 94.1 FPS at High settings and 85.9 FPS at Ultra. At 1440p, it drops to 54.1 FPS at Ultra, which is playable but not ideal. The 4K results (27.9 FPS at High, 28.9 FPS at Ultra) are below the 30 FPS playability threshold, confirming the GPU is the bottleneck at higher resolutions.

Resolution Scaling

The measured FPS data reveals a clear pattern of GPU-limited scaling as resolution increases. At 1080p Low settings, the combo delivers 183.7 FPS, which drops to 116.4 FPS at 1440p (a 36.6% reduction) and 63 FPS at 4K (a 65.7% reduction from 1080p). This scaling is typical of a GPU-bound scenario, as the CPU has sufficient headroom to maintain frame rates at lower resolutions.

At High settings, the drop from 1080p (94.1 FPS) to 1440p (55.4 FPS) represents a 41.1% decrease, while 4K (27.9 FPS) shows a 70.4% reduction from 1080p. The Ultra settings follow a similar trend: 85.9 FPS at 1080p, 54.1 FPS at 1440p (37% drop), and 28.9 FPS at 4K (66.4% drop). These consistent reduction percentages across settings indicate that the GPU's fill rate and memory bandwidth are the limiting factors, not the CPU.

The resolution scaling also reveals that the GTX 1070's 256.3 GB/s memory bandwidth and 107.7 GPixel/s pixel rate are insufficient for 4K gaming in this title. The largest relative drop occurs between 1440p and 4K, where FPS falls by roughly half across all settings. This is expected for a GPU with 8 GB of GDDR5 memory and a 256-bit bus, as the pixel throughput requirement quadruples from 1080p to 4K. The CPU's 83.2 GB/s memory bandwidth and 12 threads are more than adequate for this game, as evidenced by the high frame rates at 1080p where the CPU is less stressed.
