Similar Performance Alternatives

The Intel Core i5-9400 sits in a tightly packed performance cluster. Its average benchmark score of 2254 places it within 0.4% of several comparable processors. The AMD Ryzen 5 PRO 1500 scores 2246, a delta of 0.4%, meaning the i5-9400 is effectively tied with it in general compute workloads. The Intel Core i7-10710U trails by 0.3% with a score of 2248, while the i7-1068NG7 leads by 0.2% at 2259. The closest rival on the higher side is the Intel Core i3-10305 at 2264, which is 0.4% ahead. For a system builder pairing this CPU with a high-end GPU, any of these processors would deliver nearly identical frame pacing in CPU-bound scenarios, though the i5-9400's 6 cores and 6 threads give it a slight structural edge over some of these competitors in sustained workloads.

On the GPU side, the NVIDIA GeForce RTX 4090 posts an average benchmark score of 60347, a figure that places it at the 88th percentile among all GPUs. Its nearest rivals are remarkably close in aggregate scoring. The Intel Arc Pro A60 matches at 60326, a 0% delta. The AMD Radeon Pro Vega 48 scores 60140, just 0.3% behind. The AMD Radeon PRO V710 trails by 2.9% at 58657, while the AMD Radeon Pro W6600M leads by 2.5% at 61896. Despite these similar aggregate scores, the RTX 4090's underlying specifications, including 16384 shading units and 24 GB of GDDR6X memory on a 384-bit bus, make it substantially more capable in real-time gaming workloads than these workstation-oriented rivals. The benchmark database's aggregate scores do not fully capture the RTX 4090's dominance in gaming-specific tasks like rasterization throughput and ray tracing.

The combination of the i5-9400 and RTX 4090 is an unusual pairing. The CPU ranks at the 47th percentile among all processors, while the GPU ranks at the 88th percentile. This creates a system where the GPU is capable of far more than the CPU can feed in highly threaded scenarios, but for a game like Pc Building Simulator, which does not heavily tax multi-core processing, the balance proves sufficient.

The Verdict

The recorded data shows that this system clears the 60 FPS playable threshold at every resolution and every preset tested. At 1920x1080, the lowest average frame rate is 184.6 FPS on Ultra settings. At 2560x1440, the lowest average is 155.8 FPS on Ultra. Even at 3840x2160, the most demanding configuration, the Ultra preset delivers 80.5 FPS on average. Every playable setting list at every resolution includes all four presets: Low, Medium, High, and Ultra.

The verdict is unambiguous. This PC can run Pc Building Simulator at maximum settings across all tested resolutions. The 4K Ultra configuration, which is the heaviest load in the entire measurement set, still holds an average of 80.5 FPS, which is 34% above the 60 FPS threshold. At 1440p and 1080p, the margins are even larger. The system ranks 750th out of 3723 tested combinations in the database for this game, placing it in the top 20% of all configurations recorded.

CPU and GPU Roles

The data reveals a game that is far more GPU-bound than CPU-bound, but with unusual scaling characteristics. Looking at the 3840x2160 results, the jump from Low to Medium reduces average FPS from 171.1 to 124.6, a drop of 27%. Moving from Medium to High reduces it further to 88.2, and from High to Ultra it drops to 80.5. The total spread from Low to Ultra at 4K is 90.6 FPS, or 53% of the Low preset's performance.

At 2560x1440, the scaling is compressed. Low runs at 210.2 FPS, Medium at 186, High at 160.8, and Ultra at 155.8. The spread here is 54.4 FPS, a 26% reduction from Low to Ultra. At 1920x1080, the compression continues: Low at 245.5, Medium at 217, High at 188.9, and Ultra at 184.6. The spread is 60.9 FPS, or 25% of the Low preset's output.

The resolution scaling tells a clearer story. Moving from 1080p Ultra to 1440p Ultra, average FPS drops from 184.6 to 155.8, a 16% reduction. Moving from 1440p Ultra to 4K Ultra, it drops from 155.8 to 80.5, a 48% reduction. This nonlinear scaling is the signature of a GPU that begins to hit its bandwidth and pixel throughput limits at 4K. The RTX 4090's 1.01 TB/s memory bandwidth and 443.5 GPixel/s pixel rate are the relevant constraints here.

The CPU's role is comparatively modest. The i5-9400's 6-core, 6-thread configuration with a 2.90 GHz base and 4.10 GHz boost clock is sufficient to maintain high frame rates in this simulation genre. The fact that the 1080p Low preset reaches 245.5 FPS without the CPU bottlenecking suggests that Pc Building Simulator does not demand extreme single-thread performance. The game's simulation logic, which tracks component installation and PC assembly, is not computationally intensive enough to stress the i5-9400's single-core performance, which scores 935 in Cinebench R23 single-core.

The practical conclusion is that at 1080p and 1440p, the GPU has so much headroom that the CPU becomes the limiting factor only in the sense that it cannot push beyond roughly 245 FPS. At 4K, the GPU becomes the clear bottleneck, and the CPU's role recedes further. For players targeting 60 FPS, neither component is ever the limiting factor, as all configurations exceed the threshold by wide margins.

Q: Does any preset at any resolution fall below 60 FPS?

A: No. Every preset at every tested resolution, from Low to Ultra and from 1080p to 4K, maintains an average FPS above 60. The lowest recorded average is 80.5 FPS at 4K Ultra.

Measured FPS Breakdown

At 1920x1080, the Low preset delivers an average of 245.5 FPS. Medium produces 217 FPS. High produces 188.9 FPS. Ultra produces 184.6 FPS. The step from Low to Medium is a 28.5 FPS reduction, while the step from High to Ultra is only 4.3 FPS, indicating diminishing returns at the highest preset.

At 2560x1440, Low averages 210.2 FPS. Medium averages 186 FPS. High averages 160.8 FPS. Ultra averages 155.8 FPS. The gap between High and Ultra narrows to 5 FPS, continuing the pattern seen at 1080p where the Ultra preset adds little visual cost beyond High.

At 3840x2160, Low averages 171.1 FPS. Medium averages 124.6 FPS. High averages 88.2 FPS. Ultra averages 80.5 FPS. This resolution shows the largest relative drops between presets, with the Medium to High transition costing 36.4 FPS, the steepest single-step reduction in the entire measurement set. The min and max FPS values were not recorded for any configuration, so the analysis relies on averages alone.

The full data set shows a consistent pattern: the gap between Low and Medium is always substantial, the gap between Medium and High is moderate, and the gap between High and Ultra is minimal. At 4K, however, the Medium to High drop is severe, suggesting that the High preset introduces effects that are particularly demanding at high pixel counts.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which runs at 184.6 FPS average. This is the maximum quality setting available in the test, and it clears the threshold by 208%.

At 2560x1440, Ultra is again the best choice, running at 155.8 FPS average. The margin above the 60 FPS threshold is 160%.

At 3840x2160, Ultra remains the best setting, with an average of 80.5 FPS. This is 34% above the threshold, which is a comfortable margin for a 4K maximum-quality configuration.

In every case, the recommendation is the same: use Ultra settings. The RTX 4090 provides enough performance headroom at all resolutions that there is no reason to reduce quality. The i5-9400 does not interfere with this outcome, as the game's demands on the CPU are modest enough that the processor keeps pace at all tested settings. The only scenario where a player might consider lowering settings would be to pursue refresh rates beyond 240 Hz at 1080p, where the 245.5 FPS Low preset result suggests the system can approach the limits of high-refresh displays. For standard 60 Hz, 144 Hz, or even 240 Hz displays, the Ultra preset at any resolution provides sufficient frame rates.
