Minecraft: Java Edition

The Intel Core i5-9400 and AMD Radeon RX 6600 combination delivers a clear performance curve in Minecraft: Java Edition, with the data showing that resolution scaling heavily favors the CPU at lower settings. At 1080p with Low settings, the combo produces an average of 354.7 FPS, which drops to 279.9 FPS at Medium and 221.6 FPS at High. Moving to 1440p, the same preset ladder yields 222.5, 179.4, and 142.5 FPS respectively. At 4K, the numbers fall further to 114.9, 94.4, and 71.9 FPS. The Ultra preset, however, tells a different story: it produces 141.8 FPS at 1080p, 88.4 FPS at 1440p, and just 48.7 FPS at 4K. The gap between Low and Ultra at 1080p is 213 FPS, but at 4K that gap shrinks to 66.2 FPS, indicating that the GPU becomes the limiting factor as resolution climbs.

The 4K Ultra result of 48.7 FPS is notably below the 60 FPS threshold, while the 1440p Ultra figure of 88.4 FPS remains playable. The data suggests that the RX 6600’s 8 GB of GDDR6 memory and 224.0 GB/s bandwidth are adequate for most presets, but the Ultra preset’s demands at 4K exceed what this combo can sustain. Conversely, the 1080p Low result of 354.7 FPS indicates that the CPU, with its 6 cores and 6 threads, is not the bottleneck at lower resolutions. The scaling pattern—where FPS drops by roughly 37% from 1080p to 1440p at Low settings—points to a balanced system that shifts toward GPU-bound behavior only at the highest resolution and quality settings.

Resolution Scaling

The measured FPS data reveals a predictable pattern: as resolution increases, average frame rates decline across all presets, but the magnitude of the drop varies significantly by quality setting. At Low settings, the transition from 1080p to 1440p reduces FPS from 354.7 to 222.5, a decrease of 132.2 FPS. From 1440p to 4K, the drop is 107.6 FPS, landing at 114.9. This steep decline indicates that even at Low settings, the GPU is working harder at higher resolutions, though the absolute numbers remain high enough for smooth gameplay. At Medium settings, the same resolution steps yield 279.9, 179.4, and 94.4 FPS, with the 1440p-to-4K drop of 85 FPS being the largest single-step decline. High settings show 221.6, 142.5, and 71.9 FPS, where the 4K result dips below the 72 FPS mark. Ultra settings produce the most dramatic scaling: 141.8, 88.4, and 48.7 FPS, with the 4K figure falling below 50 FPS.

The scaling behavior at Ultra settings is particularly telling. The 1080p-to-1440p drop of 53.4 FPS is substantial, but the 1440p-to-4K drop of 39.7 FPS is proportionally smaller. This suggests that at Ultra, the combo is already near its limits at 1440p, and the additional resolution strain yields diminishing returns in FPS loss. For the other presets, the 1080p-to-1440p drop is consistently larger than the 1440p-to-4K drop, which implies that the GPU’s rendering pipeline is more efficient at lower resolutions and becomes saturated as pixel count rises. The data indicates that the RX 6600, with its boost clock of 2491 MHz and 1792 shading units, handles 1080p and 1440p with ease, but 4K Ultra exceeds its practical capacity.

How This Combo Ranks

In the benchmark database, this specific CPU-GPU combination ranks 1408 out of 1727 tested combos for Minecraft: Java Edition. That places it in the lower half of all pairings, which is surprising given the high FPS numbers measured. The rank reflects the relative performance of this combo against all others, and a rank of 1408 out of 1727 means roughly 81% of tested combos outperform it. This suggests that while the i5-9400 and RX 6600 deliver playable frame rates, other combinations—likely those with newer CPUs or higher-tier GPUs—achieve better results. The CPU’s benchmark percentile of 50 versus all CPUs indicates it is exactly average, while the GPU’s percentile of 69 versus all GPUs shows it is above average. This mismatch explains the ranking: the CPU holds the combo back relative to systems with stronger processors.

The combo’s rank is not a reflection of poor absolute performance, but rather of the competitive field. For context, the RX 6600’s nearest rivals in overall GPU benchmarks include the AMD Radeon 890M with a delta of 0%, the AMD Radeon RX 580 2048SP at -0.2%, and the AMD Radeon RX 6700M at +0.2%. The i5-9400’s nearest rivals include the Intel Core i3-10305 at +0.2% and the Intel Core i7-8809G at -0.6%. These close deltas indicate that small benchmark differences translate into significant rank changes in a crowded field. The data shows that this combo sits in a mid-tier position, capable of high FPS in this game but not at the top of the leaderboard.

GPU Role

The AMD Radeon RX 6600 plays a critical role in the measured results, particularly at higher resolutions and settings. The GPU’s 8 GB of GDDR6 memory on a 128-bit bus provides a bandwidth of 224.0 GB/s, which is sufficient for 1080p and 1440p gaming but becomes stressed at 4K Ultra. The boost clock of 2491 MHz and game clock of 2044 MHz are the key clock figures that drive performance. The GPU’s 1792 shading units, 112 texture mapping units, and 64 render output units determine its pixel and texture throughput, with a pixel rate of 159.4 GPixel/s and a texture rate of 279.0 GTexel/s. These specifications explain why the GPU excels at lower resolutions: it can process pixels quickly, but the 4K Ultra preset’s demands overwhelm its capacity.

The GPU’s benchmark scores corroborate the FPS data. The PassMark G3D score of 15096 places it in the 69th percentile of all GPUs, and its average benchmark score of 25235 is nearly identical to the AMD Radeon 890M (25246) and AMD Radeon RX 6700M (25180). The DirectX 12 score of 51 in PassMark is low, but the Vulkan score of 80492 in Geekbench is strong, suggesting the GPU is well-optimized for APIs that Minecraft: Java Edition can leverage. The GPU’s 8 GB VRAM is not a limiting factor at 1080p or 1440p, but at 4K Ultra, the combination of high-resolution textures and effects likely saturates the memory bandwidth, contributing to the 48.7 FPS result. The data indicates that the GPU is the primary constraint at 4K Ultra, while the CPU handles lower settings without issue.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for this combo depend on the target resolution and desired frame rate. At 1080p, the Low preset delivers 354.7 FPS, which is excessive for most displays, while the Ultra preset at 141.8 FPS is still well above the 60 FPS threshold. The Medium preset at 279.9 FPS and High at 221.6 FPS both provide headroom for V-Sync or high-refresh monitors. For 1440p, the Low preset at 222.5 FPS remains very high, Medium at 179.4 FPS is smooth, and High at 142.5 FPS is excellent. The Ultra preset at 88.4 FPS is playable but approaches the lower bound for competitive play. At 4K, the Low preset at 114.9 FPS is the only option that exceeds 60 FPS comfortably; Medium at 94.4 FPS is acceptable, High at 71.9 FPS is borderline, and Ultra at 48.7 FPS is not recommended.

The data suggests that High settings at 1080p or 1440p offer the best balance of visual quality and performance. At 1080p, High provides 221.6 FPS, which is more than enough for any display. At 1440p, High yields 142.5 FPS, still above the 120 FPS mark for high-refresh monitors. For users who prioritize maximum visual fidelity, Ultra at 1080p (141.8 FPS) is viable, and Ultra at 1440p (88.4 FPS) is acceptable for slower-paced gameplay. At 4K, users should stick to Low or Medium presets to maintain smooth frame rates, as the Ultra preset’s 48.7 FPS falls below the standard 60 FPS target. The measured data shows no min or max FPS values, so the average scores are the sole basis for these recommendations.
