Minecraft: Java Edition

Minecraft: Java Edition with the Intel Core i5-9400 and AMD Radeon RX 6800 XT produces a performance profile that is heavily dictated by resolution and settings. The data shows a system capable of extreme frame rates at lower resolutions, but one where the CPU becomes a clear limiting factor as resolution drops. This analysis walks through the measured results to determine the optimal settings and understand the balance between the six-core processor and the high-end GPU.

Settings Recommendations

The measured FPS data across all resolutions indicates that the "Medium" preset offers the most balanced experience, providing high frame rates without the performance penalty of the "Ultra" preset. At 1920x1080, Medium delivers 419.5 FPS, which is 11.3% lower than the 453.1 FPS seen at Low, but it is a substantial 81.1% higher than the 231.6 FPS at Ultra. The jump from Medium to High at 1080p results in a 12.7% drop to 372.4 FPS, suggesting that the visual gains from High may not justify the loss in frame rate for competitive play.

At 2560x1440, the Medium preset again proves to be the sweet spot, producing 294.6 FPS. This is 21.4% lower than the 374.9 FPS at Low, but it is more than double the 144.8 FPS achieved at Ultra. The High preset at 1440p yields 233.2 FPS, which is a 20.9% decrease from Medium. For 3840x2160, the situation becomes more critical. The Medium preset delivers 156.8 FPS, which is 20.2% lower than the 196.4 FPS at Low, but it remains far more playable than the 77.1 FPS at Ultra. The High preset at 4K drops to 120.3 FPS, a 23.3% reduction from Medium.

The "Ultra" preset consistently shows a severe performance cost across all resolutions. At 4K, it delivers 77.1 FPS, which is under half the frame rate of the Medium preset at the same resolution. Given that the data shows no minimum FPS values, the average figures alone suggest that Ultra is not recommended for a consistently smooth experience, especially at higher resolutions. The optimal choice is the Medium preset, as it provides the best compromise between visual fidelity and performance, keeping frame rates well above 144 FPS at both 1080p and 1440p, and above 60 FPS at 4K.

How This Combo Ranks

The combo of the Intel Core i5-9400 and AMD Radeon RX 6800 XT ranks 644th out of 1727 tested combinations for Minecraft: Java Edition. This places the system in the upper-middle tier of all tested hardware pairings. The rank suggests that while the GPU is a high-performing part, the overall combination is held back by the CPU in this specific title.

The RX 6800 XT alone sits in the 87th percentile of all GPUs, with an average benchmark score of 49982. Its nearest rivals in the GPU benchmark database include the Intel Arc A550M, which scores 49737 (a 0.5% difference), and the NVIDIA RTX A1000, which scores 50826 (a -1.7% difference). The GPU is also close to the NVIDIA GeForce RTX 4070 Ti SUPER, which scores 48704, a 2.6% difference. This indicates the GPU is a strong performer on its own.

In contrast, the Core i5-9400 sits in the 50th percentile of all CPUs, with an average benchmark score of 2305. Its nearest rivals include the Intel Core i3-10305, which scores 2300 (a 0.2% difference), and the Intel Core i7-8809G, which scores 2319 (a -0.6% difference). The CPU’s mid-pack ranking, combined with the GPU’s top-tier ranking, explains the combo’s 644th position. The data suggests that the system is not performing to the GPU’s full potential, as the CPU is a relative weak link in this pairing.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings presets. At 1920x1080, the combo delivers exceptionally high frame rates. The Low preset achieves 453.1 FPS, which is the highest figure recorded. The Medium preset produces 419.5 FPS, while the High preset yields 372.4 FPS. The Ultra preset drops significantly to 231.6 FPS. The progression from Low to Ultra at 1080p shows a 48.9% reduction in performance.

At 2560x1440, the frame rates remain high but show a clear scaling pattern. The Low preset delivers 374.9 FPS, which is 17.3% lower than the same preset at 1080p. The Medium preset produces 294.6 FPS, a 29.8% drop from its 1080p counterpart. The High preset achieves 233.2 FPS, a 37.4% decrease from 1080p. The Ultra preset yields 144.8 FPS, a 37.5% reduction from 1080p.

At 3840x2160, the performance impact of the higher resolution is evident. The Low preset delivers 196.4 FPS, which is 56.7% lower than at 1080p. The Medium preset produces 156.8 FPS, a 62.6% drop from 1080p. The High preset achieves 120.3 FPS, a 67.7% reduction from 1080p. The Ultra preset yields 77.1 FPS, a 66.7% decrease from 1080p. The data shows a consistent pattern where each increase in resolution results in a significant frame rate penalty, with the penalty being more pronounced at higher settings.

Resolution Scaling

The FPS data reveals a clear scaling trend as resolution increases from 1920x1080 to 3840x2160. For the Low preset, the frame rate drops from 453.1 FPS at 1080p to 374.9 FPS at 1440p, a 17.3% reduction. Moving from 1440p to 4K, the frame rate drops to 196.4 FPS, a 47.6% reduction. The total decrease from 1080p to 4K is 56.7%.

For the High preset, the scaling is steeper. The frame rate drops from 372.4 FPS at 1080p to 233.2 FPS at 1440p, a 37.4% reduction. Moving to 4K, it drops to 120.3 FPS, a 48.4% reduction from 1440p. The total decrease from 1080p to 4K is 67.7%. The Ultra preset shows a similar pattern, dropping from 231.6 FPS at 1080p to 144.8 FPS at 1440p (a 37.5% reduction) and then to 77.1 FPS at 4K (a 46.8% reduction from 1440p).

The larger percentage drops at higher settings suggest that the GPU is becoming more of a limiting factor at 4K. However, the fact that the frame rates at 1080p are exceptionally high, exceeding 450 FPS on Low, indicates that the CPU is the primary bottleneck at lower resolutions. The game is likely CPU-bound at 1080p, where the Core i5-9400’s six cores are maxed out, preventing the RX 6800 XT from reaching even higher frame rates. As resolution increases, the load shifts to the GPU, which is better equipped to handle the additional pixels, but the overall frame rate still drops due to the increased rendering workload.

CPU Role

The Intel Core i5-9400 is a six-core, six-thread processor based on the Coffee Lake architecture. It has a base clock of 2.90 GHz and a boost clock of 4.10 GHz. The CPU has a 9 MB shared L3 cache and supports DDR4 memory with a dual-channel bus. Its benchmark scores include a Cinebench R23 multi-core score of 7969 and a single-core score of 1125. These figures are consistent with a mid-range processor from its generation.

In Minecraft: Java Edition, the CPU’s role is critical. The game is known to be heavily dependent on single-threaded performance, and the Core i5-9400’s boost clock of 4.10 GHz is a key factor in achieving high frame rates. The data shows that at 1080p with Low settings, the combo reaches 453.1 FPS, which suggests the CPU is working near its limit. The fact that the frame rate does not scale linearly with resolution at lower settings indicates that the CPU is the bottleneck at 1080p.

The CPU’s 50th percentile ranking among all CPUs, with an average score of 2305, places it in the middle of the pack. Its nearest rival, the Intel Core i3-10305, scores 2300, a mere 0.2% difference. This proximity in performance suggests that the i5-9400 is not a standout part, and its six cores without hyper-threading may limit performance in scenarios that benefit from additional threads. However, for Minecraft: Java Edition, the single-core boost clock is the more important factor, and the data shows that the CPU is capable of driving very high frame rates at lower resolutions, though it does cap the system’s ultimate potential.
