Minecraft: Java Edition

Minecraft: Java Edition with the Intel Core i5-9400 and AMD Radeon RX 6600 XT presents a dataset where frame rates are exceptionally high across all tested configurations, indicating a system with substantial headroom for this title. The measured data shows a clear hierarchy governed primarily by resolution and graphics preset, with the combination ranking 1193 out of 1727 tested combos. The following analysis breaks down the measured FPS figures, focusing on how the system scales with workload and where the primary performance bottlenecks lie.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial, revealing how the rendering load shifts between the CPU and GPU. At 1080p with Low settings, the system produces 390 FPS, but this falls to 126.1 FPS at 4K with the same preset—a reduction of approximately 68%. This dramatic decline indicates that at lower resolutions, the frame rate is largely dictated by the processor's ability to feed the renderer, while the GPU has ample capacity. As resolution increases, the GPU becomes the limiting factor, as evidenced by the 4K Ultra result of 50 FPS, which is a 68% drop from the 1080p Ultra figure of 155.3 FPS.

The scaling pattern is consistent across all settings presets. Moving from 1440p to 4K at High settings, the average FPS drops from 152.4 to 81.1, a 47% reduction. Similarly, the Medium preset falls from 196.7 FPS at 1440p to 103.7 FPS at 4K. This consistent proportional decline suggests a balanced scaling behavior where the GPU's pixel throughput becomes progressively more stressed. However, the absolute numbers remain high even at 4K, with the Low preset still exceeding 120 FPS, indicating that the RX 6600 XT is never fully overwhelmed by this game's rendering demands.

The gap between 1080p and 1440p is smaller than the gap between 1440p and 4K. For example, at Ultra settings, the system delivers 155.3 FPS at 1080p, 97 FPS at 1440p, and 50 FPS at 4K. The 38% drop from 1080p to 1440p is less severe than the 48% drop from 1440p to 4K. This suggests that the GPU's memory bandwidth and shading capabilities handle the intermediate resolution efficiently, but the jump to 4K quadruples the pixel count, pushing the renderer into a more demanding regime where the GPU's 256.0 GB/s bandwidth and 10.60 TFLOPS compute become more significant constraints.

Settings Recommendations

Based on the measured rows, the optimal experience depends on the target display resolution. For 1080p displays, the Ultra preset delivers 155.3 FPS, which is more than sufficient for smooth gameplay on high-refresh monitors. The data shows that High settings at 1080p yield 243.5 FPS, a 57% increase over Ultra, but the visual fidelity difference may not justify the frame rate gain for most users. The Medium preset at 309.3 FPS and Low at 390 FPS are excessive for typical 60-144 Hz displays, making them unnecessary compromises unless aiming for absolute maximum frame rates.

At 1440p, the High preset provides 152.4 FPS, which aligns well with 144 Hz monitors. The Ultra preset drops to 97 FPS, which is still playable but falls short of the highest refresh rates. The Medium preset at 196.7 FPS offers a compelling middle ground, delivering nearly 200 FPS while retaining higher visual quality than Low. For 4K displays, the Medium preset at 103.7 FPS is the most balanced option, as High drops to 81.1 FPS and Ultra falls to 50 FPS. The Low preset at 126.1 FPS is viable for competitive play but sacrifices most graphical enhancements.

The data suggests that the High preset offers the best balance of visual quality and performance across all resolutions. At 1080p, it produces 243.5 FPS, at 1440p it achieves 152.4 FPS, and at 4K it maintains 81.1 FPS. This consistency makes High the recommended default, with Ultra reserved for users who prioritize image quality over frame rate and who play at 1080p or 1440p.

GPU Role

The AMD Radeon RX 6600 XT is the primary driver of the measured performance at higher resolutions. The GPU's specifications include 8 GB of GDDR6 memory on a 128-bit bus, yielding 256.0 GB/s of bandwidth. This memory configuration is sufficient for Minecraft's texture and chunk data, as evidenced by the strong performance even at 4K. The GPU's 2048 shading units, 128 texture mapping units, and 64 render output units process the game's geometry and pixel work efficiently, with a pixel rate of 165.7 GPixel/s and a texture rate of 331.4 GTexel/s.

The clock speeds show a base of 1968 MHz, a game clock of 2359 MHz, and a boost clock of 2589 MHz. These high frequencies contribute to the GPU's ability to maintain high frame rates across all settings. The 32 ray tracing cores are present but underutilized in Minecraft: Java Edition, which does not implement hardware ray tracing in the same manner as other titles. The GPU's FP32 performance of 10.60 TFLOPS provides ample compute for the game's shader-based rendering.

The GPU's benchmark scores place it in the 71st percentile among all GPUs, with an average benchmark score of 27985. Its nearest rival, the NVIDIA GeForce GTX 980 Ti, scores 27956, a delta of 0.1%, indicating a near-identical overall compute capability. However, the RX 6600 XT's modern architecture and higher memory bandwidth give it an edge in titles that leverage newer features. The measured FPS data shows that the GPU is not the bottleneck at 1080p, as frame rates exceed 240 FPS even at High settings, but becomes more influential as resolution increases.
