Minimum

The Intel Core i5-9400 paired with the NVIDIA GeForce RTX 3070 delivers a highly playable experience in Minimum, but the data reveals a clear performance ceiling defined by the graphics card. Across all measured resolutions, the frame rate scales predictably with both resolution and settings, with the most significant drop occurring when moving from 1440p to 4K. The RTX 3070, which sits at the 61st percentile of all GPUs, is the primary driver of performance, while the i5-9400, at the 47th percentile of CPUs, provides sufficient headroom to avoid becoming the main bottleneck at higher resolutions. Benchmark results indicate that this combination is best suited for 1440p gaming, where it can consistently deliver high refresh rates, while 4K requires a compromise on settings to maintain smooth gameplay.

Resolution Scaling

The measured FPS data for this combination shows a distinct pattern: as resolution increases, the average frame rate decreases significantly, with the largest relative jump occurring between 2560x1440 and 3840x2160. At 1080p with Ultra settings, the system produces 112 FPS, but at 4K Ultra, that figure drops to just 39 FPS, a reduction of 73 FPS. This steep decline indicates that the GPU is the limiting component at 4K, as the pixel count overwhelms the RTX 3070's 8 GB GDDR6 memory and 448.0 GB/s bandwidth.

The scaling from 1080p to 1440p is more moderate. At High settings, the average drops from 147 FPS at 1080p to 95 FPS at 1440p, a 52 FPS difference. This suggests that the GPU still has enough resources to handle the increased pixel load, but the gap widens considerably when stepping up to 4K, where the High preset only manages 51 FPS. The data shows that the transition from 1440p to 4K is the most punishing, with the average FPS nearly halving at High settings.

When looking at the Low preset, the same pattern emerges. At 1080p Low, the system hits 229 FPS, which drops to 148 FPS at 1440p and then to 79 FPS at 4K. The 4K Low result is still playable, but it represents a 150 FPS loss from 1080p Low. This suggests that while the CPU can push high frame rates at lower resolutions, the GPU's rendering capacity at 4K caps the output regardless of settings. The scaling behavior indicates that the RTX 3070 is the primary limiting factor at 4K, whereas at 1080p, the CPU's six cores and six threads are sufficient to keep the GPU fed.

GPU Role

The NVIDIA GeForce RTX 3070 is the cornerstone of this build's gaming performance, and its specifications directly explain the measured results. With 8 GB of GDDR6 memory on a 256-bit bus, the GPU delivers 448.0 GB/s of bandwidth, which is ample for 1080p and 1440p gaming but becomes strained at 4K. The card's boost clock of 1725 MHz and 5888 shading units allow it to process geometry and textures efficiently, as evidenced by the 3DMark Steel Nomad DX12 score of 3162 and a Passmark G3D score of 22214.

In the game's own benchmarks, the GPU's role is most apparent in the 4K results. At 4K Ultra, the average FPS drops to 39, which is below the 60 FPS threshold for smooth gameplay. Even at 4K High, the system only achieves 51 FPS, indicating that the GPU is working near its limit. The 4K Medium result of 61 FPS, with a minimum of 52 FPS and maximum of 70 FPS, shows that the card can handle 4K if settings are adjusted, but the margin for error is thin.

Comparatively, the RTX 3070's nearest rivals in the GPU benchmark database include the AMD Radeon RX 7600 XT, which scores 0.7% higher, and the NVIDIA GeForce GTX 690, which is 1% higher. The RTX 3070 outperforms the NVIDIA Tesla K40c by 1.5%. This close grouping suggests that the RTX 3070 is a mid-to-high-tier card, and its performance in Minimum aligns with its 61st percentile ranking among all GPUs. The card's 20.31 TFLOPS of FP32 compute power is evident in the high frame rates at 1080p and 1440p, where it can push past 200 FPS on Low settings.

CPU Role

The Intel Core i5-9400 provides a solid foundation for this gaming configuration, though its role is secondary to the GPU in determining frame rates. With six cores and six threads, a base clock of 2.90 GHz, and a boost clock of 4.10 GHz, this Coffee Lake processor is capable of handling the game's logic without becoming a bottleneck at higher resolutions. The CPU's 9 MB of shared L3 cache and dual-channel DDR4 memory support with 42.7 GB/s bandwidth ensure that data flows efficiently to the GPU.

Benchmark results for the i5-9400 show a Cinebench R23 multi-core score of 6629 and a single-core score of 935, placing it at the 47th percentile of all CPUs. Its nearest rivals, such as the Intel Core i7-1068NG7 and the AMD Ryzen 5 PRO 1500, have average scores within 0.4% of the i5-9400, indicating it is a competent mid-range processor. In Minimum, the CPU's influence is most noticeable at 1080p, where the system achieves 229 FPS on Low settings. This high frame rate suggests that the CPU can keep up with the GPU's output at lower resolutions, but the GPU becomes the limiting factor as resolution increases.

At 4K, the CPU's workload decreases relative to the GPU, as the graphics card handles the bulk of the rendering. The measured FPS at 4K Low (79 FPS) versus 4K Ultra (39 FPS) demonstrates that the GPU's performance scales with settings, while the CPU maintains a consistent frame delivery. The i5-9400's 6 threads are sufficient for this game, and there is no evidence of a CPU bottleneck in the data, as the frame rates are primarily dictated by the resolution and settings applied to the GPU.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this configuration depend on the target resolution. For 1440p, which is the recommended resolution for this combo, the High preset delivers 95 FPS on average, providing a smooth and visually detailed experience. The Medium preset at 1440p offers a slightly higher average of 113 FPS and a minimum of 96 FPS, making it the safest choice for competitive play where frame consistency is paramount. The Ultra preset at 1440p drops to 72 FPS, which is still playable but sacrifices the headroom provided by High or Medium.

For 1080p, the Low preset achieves an impressive 229 FPS, ideal for high-refresh-rate monitors, while High still delivers 147 FPS. The Ultra preset at 1080p yields 112 FPS, which is respectable but not necessary given the performance available at lower settings. At 4K, the Medium preset is the only viable option, with 61 FPS on average and a minimum of 52 FPS, while High drops to 51 FPS and Ultra to 39 FPS. Users prioritizing visual fidelity at 4K should accept the lower frame rates, but for a balanced experience, Medium is the recommended preset.

The data suggests that the High preset at 1440p offers the best overall experience, balancing frame rate and visual quality. For users who demand the highest frame rates, the Low preset at 1080p is the top choice, while those with 4K displays should stick to Medium settings to avoid sub-60 FPS performance. The measured rows indicate that this system is versatile, but its strengths lie in 1440p and 1080p gaming.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across all resolutions and settings. At 1920x1080, the system demonstrates its peak capabilities: the Low preset achieves 229 FPS on average, while Medium hits 175 FPS with a minimum of 149 FPS and a maximum of 201 FPS. High reaches 147 FPS, and Ultra drops to 112 FPS. These numbers show that at 1080p, the RTX 3070 is rarely constrained, and the CPU can support high frame rates.

Moving to 2560x1440, the performance scales down but remains strong. Low yields 148 FPS, Medium averages 113 FPS with a minimum of 96 FPS and a maximum of 130 FPS, High produces 95 FPS, and Ultra drops to 72 FPS. The gap between High and Ultra at 1440p is 23 FPS, indicating that the Ultra preset's additional graphical demands significantly impact performance.

At 3840x2160, the GPU's limits become evident. Low averages 79 FPS, Medium achieves 61 FPS with a minimum of 52 FPS and a maximum of 70 FPS, High falls to 51 FPS, and Ultra bottoms out at 39 FPS. The difference between 1080p Low and 4K Low is 150 FPS, underscoring the massive impact of resolution on this hardware. The Medium preset at 4K is the only one that maintains an average above 60 FPS, making it the baseline for 4K playability. Across all resolutions, the Medium preset consistently provides the most stable frame times, as indicated by the recorded minimum and maximum values, making it a reliable choice for consistent performance.
