The Intel Core i5-9400 sits in a narrow performance band where several processors deliver nearly identical average benchmark scores. The closest match is the Intel Core i7-1068NG7, which scores 2259 compared to the i5-9400's 2254, a delta of only -0.2%. The Intel Core i3-10305 scores 2264, putting it 0.4% ahead, while the AMD Ryzen 5 PRO 1500 scores 2246, just 0.4% behind. The Intel Core i7-10710U completes the group with 2248, a 0.3% difference. In practical terms, all four rivals would produce nearly indistinguishable frame rates in CPU-bound scenarios. The i5-9400's 6 cores and 6 threads, with a base clock of 2.90 GHz and boost of 4.10 GHz, place it in the 47th percentile of all CPUs, meaning it sits slightly below the midpoint of the entire CPU landscape.

On the GPU side, the NVIDIA GeForce RTX 5080 occupies a much higher performance tier, sitting in the 87th percentile of all GPUs. Its nearest rivals cluster within a few percentage points. The AMD Radeon 8060S scores 55757 against the RTX 5080's 56083, a delta of 0.6%. The AMD Radeon RX 6750 GRE 12 GB scores 55698, just 0.7% behind, while the AMD Radeon Pro W5700X scores 54828, trailing by 2.3%. The AMD Radeon RX 9070 GRE actually scores higher at 57367, putting it 2.2% ahead of the RTX 5080. For Pc Building Simulator, any of these GPUs would deliver similar headroom, with the RTX 5080's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth proving far more than this simulation title requires. The GPU's average benchmark score of 56083 dwarfs the CPU's 2254, which signals where the bottleneck lies in this pairing.

CPU and GPU Roles

The measured frame rates reveal a system where the GPU is not the limiting factor at any resolution. At 1920x1080 with Low settings, the combo produces 245.9 FPS. Moving to Medium drops this to 217.7 FPS, then High and Ultra both land at 188.1 FPS. The fact that Ultra matches High exactly at 1080p suggests the CPU is capping performance once the GPU workload becomes light enough. At 2560x1440, the pattern shifts. Low settings yield 211.2 FPS, Medium 183.2 FPS, High 160.1 FPS, and Ultra 147.4 FPS. The spread between settings is larger here, indicating the GPU begins to matter more, but the CPU still provides ample headroom. At 3840x2160, the GPU takes clear control. Low settings produce 163.9 FPS, Medium 115.7 FPS, High 84.7 FPS, and Ultra 75.6 FPS. The scaling from 1080p Low to 4K Low shows a drop from 245.9 to 163.9 FPS, a 33% reduction. From 1080p Ultra to 4K Ultra, the drop is from 188.1 to 75.6 FPS, a 60% reduction.

The data indicates that at 1080p, the i5-9400's six threads become the primary constraint, particularly at higher presets where the frame rate plateaus. At 1440p, the balance shifts toward the GPU, but the CPU still delivers enough throughput to keep frame rates well above the 60 FPS threshold. At 4K, the RTX 5080's workload dominates, and the CPU's role diminishes. For a simulation game like Pc Building Simulator, which relies on physics calculations and system state tracking, the CPU's single-thread performance matters. The i5-9400's Cinebench R23 single-core score of 935 and Geekbench single-core score of 1389 are modest by modern standards, but they prove sufficient for this title's demands. The recorded data shows that even the most demanding preset at 4K stays above 75 FPS, meaning neither component becomes a critical failure point.

How This Combo Ranks

The combination of the Intel Core i5-9400 and NVIDIA GeForce RTX 5080 ranks 770th out of 3723 tested combos in Pc Building Simulator. This places it in the top 20.7% of all configurations tested in the database. The rank reflects the unusual pairing of a mid-range 2018 CPU with a top-tier 2025 GPU. The i5-9400's 47th percentile CPU score drags the combo down, while the RTX 5080's 87th percentile GPU score lifts it. For a game that is not graphically demanding, the GPU's raw power matters less than the CPU's ability to maintain consistent frame pacing. The data confirms this: at 1080p, the combo achieves 188.1 FPS at Ultra, which is identical to the High preset, indicating the CPU has reached its effective ceiling. At 4K, the combo still delivers 75.6 FPS at Ultra, which is a strong result. The rank of 770 out of 3723 means there are 769 combos that perform better, but also 2953 that perform worse. This places the pairing comfortably in the upper tier of tested systems for this title, despite the CPU's age.

The gap between the CPU and GPU performance percentiles is notable. A more balanced pairing would typically have components within 20 percentile points of each other. Here, the gap is 40 points. However, Pc Building Simulator's modest requirements mean this imbalance does not cause playability issues. The recorded data shows all resolutions and presets clear 60 FPS, so the rank is more a reflection of theoretical headroom than practical limitations.

The Verdict

This PC can run Pc Building Simulator at all tested resolutions and presets. The verdict by resolution confirms that every combination of resolution and preset clears the 60 FPS threshold. At 3840x2160, the playable settings include Low, Medium, High, and Ultra, with the best setting being Ultra at 75.6 FPS. At 2560x1440, all four presets are playable, with Ultra delivering 147.4 FPS. At 1920x1080, all presets are playable, with Ultra reaching 188.1 FPS. The data shows no configuration falls below the playable threshold. The minimum recorded average across all tests is 75.6 FPS, which is 15.6 FPS above the 60 FPS requirement.

The CPU's age does not prevent it from handling this simulation title. The i5-9400's 6 cores and 6 threads, combined with a 4.10 GHz boost clock, provide enough single-thread performance for the game's systems. The RTX 5080's 56.28 TFLOPS of FP32 compute and 16 GB of GDDR7 memory are far beyond what this game needs, but they ensure no GPU-related frame drops occur. For players who want to run the game at maximum settings with high frame rates, this combo delivers. The only caveat is that at 1080p, the CPU caps performance, so players with high refresh rate monitors will see diminishing returns above 188 FPS.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 188.1 FPS. This is the highest preset available and delivers more than three times the playable threshold. Players with 144 Hz or 165 Hz monitors will be satisfied, though those with 240 Hz panels may see the CPU limit.

At 2560x1440, Ultra is also the best setting, running at 147.4 FPS. This provides a smooth experience on high refresh rate monitors and leaves substantial headroom. The gap between Ultra and High is 12.7 FPS, so players who prefer maximum visual fidelity can choose Ultra without concern.

At 3840x2160, Ultra remains the best setting, with an average of 75.6 FPS. This is the most demanding configuration tested and still clears the 60 FPS threshold by a comfortable margin. For players using 4K displays with VRR, this frame rate will appear fluid. The data shows no reason to drop below Ultra at any resolution, as even the most demanding preset stays well above the playable threshold. The RTX 5080's 16 GB of VRAM and 960.0 GB/s bandwidth ensure texture streaming and asset loading are not bottlenecks in this simulation title.
