A: The data shows a significant frame rate jump from 1080p Ultra (177.8 FPS) to 1080p Low (245.4 FPS), a 67.6 FPS difference. This large spread suggests the GPU is the primary driver at this resolution, as lowering graphical load yields substantial gains.

GPU Role

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture with a 5 nm process node and houses 35,800 million transistors on a 294 mm² die. Its memory configuration includes 12 GB of GDDR6X on a 192-bit bus, delivering a bandwidth of 504.2 GB/s and a memory clock of 1313 MHz (21 Gbps effective). The GPU operates with a base clock of 1920 MHz and a boost clock of 2475 MHz, with a TDP of 200 W and a suggested PSU of 550 W.

In Pc Building Simulator, the GPU's role is evident from the frame rate scaling across settings. At 4K resolution, the difference between Low (120.6 FPS) and Ultra (60.1 FPS) settings is a 60.5 FPS drop, showing that the RTX 4070's compute resources are heavily taxed by higher graphical presets. The card's 5888 shading units and 64 ROPs handle the simulation's rendering loads effectively, but the 158.4 GPixel/s pixel rate and 455.4 GTexel/s texture rate become limiting factors at 4K Ultra. The GPU's FP32 performance of 29.15 TFLOPS supports high frame rates at lower resolutions, where the processor can keep up with the card's output.

The RTX 4070's 81st percentile ranking among all GPUs and its aggregate benchmark score of 37283 position it as a high-midrange performer. Its nearest rival, the AMD Radeon RX Vega 56, scores 37507 (0.6% higher), while the NVIDIA GeForce RTX 4080 Mobile trails by 2.2% with a score of 38135. This data indicates the desktop 4070 is competitive with its immediate peers, though the score differences are minimal. The GPU's 12 GB of VRAM is ample for the game's textures, as evidenced by consistent performance at 1440p and 4K, but the Ultra preset at 4K still brings the average down to 60.1 FPS, suggesting memory bandwidth constraints under maximum load.

Resolution Scaling

Frame rates decline progressively as resolution increases from 1920x1080 to 3840x2160, but the scale of the drop varies significantly by settings preset. At Low settings, the system moves from 245.4 FPS at 1080p to 209.6 FPS at 1440p (a 14.6% reduction) and then to 120.6 FPS at 4K (a 42.5% reduction from 1440p). This pattern indicates that the GPU becomes the dominant limiting component at higher resolutions, as the pixel throughput requirement increases dramatically.

At Ultra settings, the scaling is steeper: 177.8 FPS at 1080p drops to 108.1 FPS at 1440p (39.2% lower) and then to 60.1 FPS at 4K (44.4% lower from 1440p). The 4K Ultra result of 60.1 FPS is barely above the 4K High result of 58.7 FPS, which is unusual—typically Ultra would be more demanding. This suggests the game's Ultra preset may introduce diminishing returns beyond High, or that the RTX 4070 hits a similar performance ceiling for both settings at this resolution. The 4K Medium result of 84 FPS sits between these extremes, confirming that the GPU's workload scales non-linearly with settings.

The gap between Low and Ultra settings widens with resolution. At 1080p, the difference is 67.6 FPS (245.4 vs 177.8), at 1440p it is 101.5 FPS (209.6 vs 108.1), and at 4K it is 60.5 FPS (120.6 vs 60.1). This pattern shows that the CPU can feed the GPU adequately at lower resolutions, but at 1440p and above, the RTX 4070's raw rendering power dictates the final frame rate. The i5-9400's six cores and 6 threads, with a boost clock of 4.10 GHz, appear sufficient to avoid bottlenecking the GPU at 1080p, but the GPU's workload becomes the clear constraint as resolution climbs.

How This Combo Ranks

The combination of the Intel Core i5-9400 and NVIDIA GeForce RTX 4070 achieves a rank of 622 out of 1769 tested combos in Pc Building Simulator. This places the pairing in the 65th percentile of all configurations, which is a strong showing for a mid-range CPU paired with a high-end GPU from the previous generation. The rank reflects a balanced system where neither component drastically undermines the other, though the GPU's higher percentile (81st) versus the CPU's (50th) suggests the processor is the weaker link in the chain.

Relative to its nearest rival CPUs, the i5-9400's aggregate benchmark score of 2305 puts it within 0.6% of the Intel Core i7-8809G (2319), which is a more powerful mobile chip. The i5-9400 also edges out the Intel Core i3-10305 (2300) and Intel Core i3-1125G4 (2299) by 0.2% each, and the Intel Xeon E-2134 (2295) by 0.4%. These narrow margins indicate that the CPU's performance is competitive with contemporary alternatives, but it does not provide a significant advantage that would boost the combo's rank substantially.

The GPU's benchmark data shows the RTX 4070 is slightly behind its nearest rival, the AMD Radeon RX Vega 56, by 0.6% in average score. This close margin means the combo's rank is not heavily influenced by GPU performance alone; rather, the CPU's mid-pack standing (50th percentile) likely pulls the overall rank down from what the GPU alone would achieve. With 1769 total combos, a rank of 622 means the system outperforms roughly 1147 other configurations, placing it well ahead of the median in this database. The measured FPS data confirms this ranking is justified, as the system delivers playable frame rates at all tested resolutions except 4K High, which still averages 58.7 FPS.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest performance across all settings. Low settings produce an average of 245.4 FPS, Medium yields 214 FPS, High reaches 184.4 FPS, and Ultra maintains 177.8 FPS. The spread from Low to Ultra is 67.6 FPS, with each settings tier reducing performance by a consistent margin: Medium drops 12.8% from Low, High drops 13.8% from Medium, and Ultra drops 3.6% from High. This suggests the game's High to Ultra transition is less demanding than the move from Medium to High, making Ultra a reasonable choice for 1080p gaming on high-refresh-rate monitors.

Moving to 2560x1440, the frame rates remain high but show a more pronounced impact from settings. Low averages 209.6 FPS, Medium drops to 167 FPS, High falls to 117 FPS, and Ultra bottoms out at 108.1 FPS. The difference between Low and Ultra at 1440p is 101.5 FPS, which is significantly larger than the 67.6 FPS spread at 1080p. This indicates that the GPU's workload at 1440p grows more quickly with higher settings, and the RTX 4070's 12 GB of VRAM and 504.2 GB/s bandwidth become more critical. The transition from High to Ultra at 1440p costs only 8.9 FPS, again showing a smaller gap than lower settings tiers.

At 3840x2160, performance drops substantially but remains usable for most settings. Low settings average 120.6 FPS, Medium produces 84 FPS, High yields 58.7 FPS, and Ultra reaches 60.1 FPS. Interestingly, Ultra outperforms High at 4K by 1.4 FPS, which is within measurement variance but notable. The 4K Low result of 120.6 FPS is more than double the 4K High result (58.7 FPS), highlighting how drastically settings affect the GPU's ability to render at this resolution. The 4K Medium result of 84 FPS offers a balanced option for 60 Hz displays, while High and Ultra both hover near the 60 FPS threshold, making them viable for adaptive sync monitors.

Across all resolutions, the Low settings preset consistently provides the highest frame rates, with the 1080p Low result of 245.4 FPS being the absolute peak. The data shows a clear trend: the system is well-suited for 1080p and 1440p gaming at high settings, while 4K requires lowering settings to Medium or below for smooth gameplay. The measured FPS values are all derived from actual testing (dataIsMeasured is true), ensuring the results reflect real-world performance rather than estimates.
