Minecraft

Minecraft with the Intel Core i5-9400 and NVIDIA GeForce RTX 4090 delivers exceptional performance across all tested settings, with frame rates that far exceed the requirements of smooth gameplay. The data shows that even at the most demanding configuration—4K Ultra—the combo maintains an average of 117 FPS, which is well above the threshold for high-refresh-rate monitors. Given the massive headroom in this pairing, the optimal experience is found at 1440p High, which balances a stunning 330 FPS average with visual fidelity, making it the sweet spot for competitive play and immersive exploration. For users prioritizing maximum fluidity over graphical detail, 1080p Low at 455 FPS is the clear choice, but the benchmark results indicate that the CPU becomes the primary limiting factor at lower resolutions, capping performance well below the GPU's theoretical ceiling.

Settings Recommendations

The measured FPS data provides a clear hierarchy for settings selection, with the most balanced experience emerging at High settings across all resolutions. At 1440p, High delivers 330 FPS, which is 107 FPS higher than Ultra and only 60 FPS lower than Low, demonstrating that the visual upgrade from Low to High costs relatively little in performance. The Medium preset at 1440p offers 359 FPS, but the marginal gain over High (29 FPS) does not justify the reduction in graphical quality, especially given that the minimum FPS at Medium (305) is only slightly better than the high-variance scenario. For 4K displays, High settings produce 187 FPS, which is a remarkable figure for a resolution that typically stresses GPUs heavily; this suggests that Minecraft's rendering workload is more CPU-bound than GPU-bound, allowing the RTX 4090 to remain underutilized. The Ultra preset at 4K drops to 117 FPS, which is still playable but represents a 37% reduction from High, making it less attractive for users with high-refresh 4K panels. The Low preset, while offering 297 FPS at 4K, is best reserved for extreme competitive scenarios where every frame matters, but the visual degradation is significant. The data indicates that High is the recommended preset for the best balance of visual quality and performance, with 1440p High providing the highest FPS-to-quality ratio in the measured set.

Resolution Scaling

The FPS progression from 1080p to 4K reveals a classic pattern of CPU and GPU load distribution. At High settings, performance drops from 385 FPS at 1080p to 330 FPS at 1440p and further to 187 FPS at 4K. This represents a 14.3% reduction from 1080p to 1440p, but a 51.4% reduction from 1440p to 4K, indicating that the GPU becomes progressively more involved as resolution increases. The Low settings tell a more revealing story: 455 FPS at 1080p, 390 FPS at 1440p, and 297 FPS at 4K. The drop from 1080p to 1440p is 14.3%, but the drop from 1440p to 4K is 23.8%, which is less severe than at High settings. This suggests that at Low settings, the CPU is the primary limiter at lower resolutions, capping frame rates around 455 FPS, while the GPU's capacity is only fully exercised at 4K. The Medium preset shows a similar trend: 418 FPS at 1080p, 359 FPS at 1440p, and 235 FPS at 4K, with the 1080p-to-1440p drop being 14.1% and the 1440p-to-4K drop being 34.5%. The Ultra preset exhibits the most extreme scaling: 321 FPS at 1080p, 223 FPS at 1440p, and 117 FPS at 4K, with a 30.5% drop from 1080p to 1440p and a 47.5% drop from 1440p to 4K. The data clearly indicates that the RTX 4090 has ample headroom at 1080p and 1440p, with the Intel Core i5-9400's six cores and six threads acting as the bottleneck. At 4K, the GPU's workload increases sufficiently to make it the primary performance driver, but even then, the CPU's limitations prevent the full utilization of the RTX 4090's capabilities, as evidenced by the 297 FPS at 4K Low versus the GPU's theoretical maximum.

Measured FPS Breakdown

At 1920x1080, the combo delivers exceptional frame rates across all settings. Low settings produce an average of 455 FPS, which is the highest recorded in the entire dataset. Medium settings yield 418 FPS with a minimum of 356 FPS and a maximum of 481 FPS, showing a 125 FPS variance that indicates some CPU-bound spikes. High settings drop to 385 FPS, while Ultra settings produce 321 FPS. The scaling from Low to Ultra shows a 29.5% performance loss, which is moderate given the visual improvements. At 2560x1440, the performance remains high but begins to show GPU influence. Low settings average 390 FPS, Medium 359 FPS (minimum 305, maximum 413), High 330 FPS, and Ultra 223 FPS. The drop from Low to Ultra is 42.8%, which is more pronounced than at 1080p, indicating that the GPU is handling a larger share of the workload. At 3840x2160, the resolution scaling becomes evident. Low settings average 297 FPS, Medium 235 FPS (minimum 200, maximum 270), High 187 FPS, and Ultra 117 FPS. The Ultra preset at 4K shows a 60.7% reduction from Low, which is the largest performance penalty in the dataset. Notably, the 4K Medium preset is the only configuration with recorded minimum and maximum FPS values, with a 70 FPS range (200-270), suggesting more consistent frame pacing at this resolution. The minimum FPS of 200 at 4K Medium is still far above playable thresholds, but the 117 FPS at 4K Ultra approaches the edge of high-refresh-rate gaming. Across all resolutions, the Low preset consistently delivers the highest frame rates, with the gap between Low and High narrowing as resolution increases, from 15.4% at 1080p to 37.1% at 4K.

How This Combo Ranks

The combo ranks 729th out of 3710 tested combinations, positioning it in the top 19.7% of all configurations. This rank is respectable but not elite, which is surprising given the RTX 4090's exceptional specifications. The Intel Core i5-9400 sits in the 47th percentile among all CPUs, with an average benchmark score of 2254. Its nearest rivals in the CPU benchmark include the Intel Core i7-1068NG7 (2259 score, -0.2% delta), the Intel Core i3-10305 (2264 score, -0.4% delta), the Intel Core i7-10710U (2248 score, 0.3% delta), and the AMD Ryzen 5 PRO 1500 (2246 score, 0.4% delta). This clustering of scores indicates that the i5-9400 performs on par with a broad range of mid-range CPUs, but it lacks the multi-core muscle of higher-tier processors. The RTX 4090, in contrast, ranks in the 88th percentile among all GPUs, with an average benchmark score of 60347. Its nearest rivals include the Intel Arc Pro A60 (60326 score, 0% delta), the AMD Radeon Pro Vega 48 (60140 score, 0.3% delta), the AMD Radeon Pro W6600M (61896 score, -2.5% delta), and the AMD Radeon PRO V710 (58657 score, 2.9% delta). The GPU's dominance is clear—it outperforms the vast majority of graphics cards—but the combo's overall rank of 729 suggests that the CPU is holding back the system in Minecraft. The data implies that pairing the RTX 4090 with a higher-end CPU would likely yield a substantially better rank, as the GPU's capabilities are not fully realized in this configuration. The 3710 tested combos span a wide range of hardware, and a rank of 729 places this system in the upper quintile, but the gap between the GPU's 88th percentile and the combo's 80.3rd percentile highlights the CPU bottleneck.

CPU Role

The Intel Core i5-9400 is a six-core, six-thread processor from the Coffee Lake architecture, built on Intel's 14 nm process node. It operates at a base clock of 2.90 GHz and a boost clock of 4.10 GHz, with a 65 W TDP. The CPU's cache structure includes 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 9 MB of shared L3 cache. Its memory support is dual-channel DDR4 with a bandwidth of 42.7 GB/s, and it connects via PCIe Gen 3 with 16 lanes. In synthetic benchmarks, the i5-9400 scores 6629 in Cinebench R23 multi-core and 935 in single-core, 2784 in Cinebench R20 multi-core and 392 in single-core, and 5141 in Geekbench multi-core with 1389 in single-core. These scores place it in the 47th percentile of all CPUs, indicating a mid-range performance level. In Minecraft, the CPU's role is critical because the game's rendering engine is heavily single-threaded. The benchmark results show that at 1080p Low, the combo achieves 455 FPS, which is likely near the CPU's maximum frame output for this game. The six cores and six threads provide sufficient parallel processing for background tasks, but the single-core performance (935 in Cinebench R23 single-core) is the limiting factor for achieving higher frame rates. The boost clock of 4.10 GHz is adequate for gaming, but the lack of hyper-threading means the CPU cannot efficiently handle the multiple threads that modern game engines generate. The measured FPS data supports this analysis: the difference between 1080p Low (455 FPS) and 1440p Low (390 FPS) is 14.3%, which is relatively small, indicating that the CPU is still the primary constraint at 1440p. Only at 4K does the GPU become the dominant factor, as evidenced by the larger performance drops at higher settings. The CPU's 9 MB of shared L3 cache is beneficial for Minecraft's world generation and entity processing, but the overall architecture limits the combo's potential. The data suggests that upgrading to a CPU with higher single-core performance or additional threads would allow the RTX 4090 to deliver even higher frame rates, particularly at 1080p and 1440p resolutions.
