Minecraft

Minecraft with the Intel Core i5-9400 and AMD Radeon RX 6650 XT delivers exceptional performance, with the data showing this combination is capable of high frame rates even at 4K resolution. The benchmark results indicate that the GPU is the primary driver of performance at higher resolutions, while the 6-core CPU provides ample headroom for the game's engine at lower settings.

Resolution Scaling

The measured FPS data reveals a clear and predictable scaling pattern across the three tested resolutions. At 1080p with High settings, the combo produces an average of 254 FPS. Moving to 1440p High drops the average to 161 FPS, a 37% reduction, and then to 84 FPS at 4K High, a further 48% reduction from 1440p. This scaling pattern is typical for a system where the GPU becomes increasingly stressed as pixel count rises.

The frame rate behavior across the Ultra preset tells a similar story but with lower absolute values. At Ultra settings, the average FPS falls from 159 at 1080p to 100 at 1440p, and then to 52 at 4K. The 4K Ultra result is the only measured scenario that dips below the 60 FPS threshold, indicating that this resolution and preset combination pushes the Radeon RX 6650 XT to its limits with this CPU.

The scaling from 1440p to 4K is particularly steep at High settings, where the frame rate drops by nearly half. This suggests that at 4K, the GPU's 8 GB of memory and 128-bit memory bus become limiting factors. In contrast, the 1080p to 1440p transition shows a more moderate decline, indicating that the system is still relatively balanced between CPU and GPU loads at those resolutions.

Notably, the Low preset at 1080p achieves an average of 405 FPS, which is more than double the 4K High result. This wide spread between the lowest and highest workload scenarios demonstrates that the RX 6650 XT has substantial headroom at lower resolutions, but the CPU's influence becomes more apparent at 1080p where the frame rates are extremely high. The data shows that this combo is best suited for 1080p and 1440p gaming, with 4K being viable only if the user accepts reduced settings.

Settings Recommendations

The measured rows provide clear guidance on which preset delivers the best experience. At 1080p, the Medium preset offers an average of 321 FPS with a minimum of 272 FPS and a maximum of 369 FPS. This is an excellent balance, as the High preset at 254 FPS and the Low preset at 405 FPS both show diminishing returns in terms of visual quality versus frame rate. The Ultra preset at 159 FPS is still highly playable but sacrifices significant performance for marginal visual gains.

At 1440p, the Medium preset again emerges as the sweet spot, delivering 202 FPS average with a minimum of 172 FPS and a maximum of 233 FPS. The High preset at 161 FPS is also very smooth, but the Medium preset's higher minimum frame rate suggests better consistency. The Ultra preset at 100 FPS is playable but the step down from Medium to Ultra costs 102 FPS, which is a substantial penalty for a single preset tier.

For 4K gaming, the data indicates that High settings at 84 FPS provide the best combination of visual fidelity and playability. The Medium preset at 106 FPS offers a slight performance boost but the gap to the Ultra preset's 52 FPS is stark. The Low preset at 133 FPS is the only 4K option that approaches the smoothness of lower resolutions, but it sacrifices too much visual quality for most users. Based on the measured rows, the Medium preset is the recommended choice for users prioritizing smooth gameplay across 1080p and 1440p, while 4K users should stick to High settings.

CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor from the Coffee Lake architecture, featuring a base clock of 2.90 GHz and a boost clock of 4.10 GHz. The CPU's L3 cache is 9 MB shared, and it supports DDR4 memory with dual-channel configuration. In synthetic benchmarks, this CPU achieves a Cinebench R23 multicore score of 6629 and a single-core score of 935, placing it in the 47th percentile among all CPUs.

The benchmark results in Minecraft suggest that the CPU is not the primary bottleneck in most scenarios. At 1080p Low, the system reaches 405 FPS, which is an extremely high frame rate that requires strong single-thread performance. The i5-9400's boost clock of 4.10 GHz appears sufficient for this game's engine, which historically relies heavily on a few threads rather than many cores. The 6-core, 6-thread configuration provides enough parallelism for the game's background tasks without introducing significant overhead.

Compared to its nearest rivals, the i5-9400's average benchmark score of 2254 is nearly identical to the Intel Core i7-1068NG7 (2259, deltaPct -0.2) and the Intel Core i3-10305 (2264, deltaPct -0.4). The AMD Ryzen 5 PRO 1500 sits at 2246 (deltaPct 0.4), showing a similarly close performance level. This indicates that the CPU's performance is competitive with these alternatives, but the game's results are more dependent on the GPU at higher resolutions.

At 4K Ultra, the frame rate drops to 52 FPS, which is below the 60 FPS threshold. This suggests that at extreme settings, the CPU's limitations may begin to surface, as the GPU is not the only factor determining performance. However, the scaling pattern from 1080p to 4K shows a consistent decline that is more characteristic of GPU-bound scenarios. The CPU's role appears to be secondary, providing sufficient processing power for the game's logic while the GPU handles the rendering workload.

How This Combo Ranks

The combination of the Intel Core i5-9400 and AMD Radeon RX 6650 XT ranks 2410 out of 3710 tested combos in Minecraft, placing it in the 35th percentile of all tested systems. This ranking is lower than what the raw FPS numbers might suggest, which indicates that many other combinations deliver even higher frame rates in this game. The data shows that this combo is solidly mid-pack, with significant room for improvement if a user were to pair the GPU with a stronger CPU.

The ranking reflects the fact that Minecraft is a highly scalable game, and many high-end CPUs paired with similar or better GPUs can achieve higher frame rates, particularly at 1080p. The i5-9400's 47th percentile CPU ranking and the RX 6650 XT's 65th percentile GPU ranking combine to produce a system that is capable but not exceptional in the broader context of all tested combos. The combo's rank of 2410 out of 3710 means that roughly 1300 combinations perform worse, but also that over 2400 perform better.

This mid-pack ranking is consistent with the system's measured performance at 1080p High (254 FPS), which is very good but not top-tier. The data indicates that the combo is best suited for users who prioritize a balance between resolution and settings, rather than those chasing maximum frame rates at competitive levels. The ranking also suggests that the GPU is the stronger component in this pairing, as its percentile ranking is higher than the CPU's, and the system's overall performance is likely constrained by the processor in some scenarios.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture with a 7 nm process node, featuring 2048 shading units, 128 texture mapping units, and 64 raster operation units. The GPU has 32 ray tracing cores and operates at a base clock of 2055 MHz with a boost clock of 2635 MHz. It is equipped with 8 GB of GDDR6 memory on a 128-bit bus, providing a bandwidth of 280.3 GB/s. In synthetic benchmarks, the GPU achieves a Passmark G3D score of 17166 and a 3DMark Steel Nomad DX12 score of 1859, placing it in the 65th percentile among all GPUs.

The benchmark results in Minecraft strongly indicate that the GPU is the dominant factor in determining frame rates at higher resolutions. At 1080p Low, the system achieves 405 FPS, but this drops to 133 FPS at 4K Low, a 67% reduction. This scaling is directly attributable to the GPU's rendering workload, as the pixel count increases fourfold from 1080p to 4K. The RX 6650 XT's 8 GB of memory is sufficient for the game's textures at all tested settings, but the 128-bit memory bus may limit performance at 4K Ultra, where the average FPS falls to 52.

The GPU's boost clock of 2635 MHz and game clock of 2410 MHz contribute to its strong performance in this game. The data shows that the GPU is capable of delivering over 250 FPS at 1080p High, which is far above the refresh rate of most monitors. Compared to its nearest rivals, the RX 6650 XT's average benchmark score of 19765 is closely matched with the NVIDIA Tesla K40m (19885, deltaPct -0.6) and the AMD FirePro W7000 (19905, deltaPct -0.7), while the AMD FirePro D300 (19637, deltaPct 0.7) and NVIDIA Quadro K5200 (19602, deltaPct 0.8) are slightly behind. This indicates that the GPU's raw compute performance is consistent with its peer group, though the game-specific results show its strengths in a real-world workload.
