Minecraft

The Intel Core i5-9400 and AMD Radeon RX 6600 combination ranks 2,818th out of 3,710 tested combos in Minecraft, placing it in the lower half of the database. This rank is heavily influenced by the CPU's modest standing—the i5-9400 sits at the 47th percentile among all CPUs—while the GPU performs more robustly, landing in the 63rd percentile among all GPUs. Despite the overall ranking, the measured FPS data reveals a system capable of delivering exceptionally high frame rates across all tested settings and resolutions, indicating that the low combo rank reflects the hardware's absolute position against far more powerful modern parts rather than a poor experience in this specific game.

How This Combo Ranks

The combo's 2,818th position out of 3,710 tested combinations places it in the 76th percentile of all combos, meaning roughly 24% of tested systems perform worse. This rank is primarily dragged down by the processor: the i5-9400's average benchmark score of 2,254 puts it in the 47th percentile of all CPUs, with its nearest rivals including the Intel Core i7-1068NG7 (0.2% faster) and the Intel Core i7-10710U (0.3% slower). The GPU, however, performs significantly better relative to its peers—the RX 6600's average score of 19,036 places it in the 63rd percentile, with its nearest rival being the NVIDIA Quadro K6000 at a 0% delta and the NVIDIA GeForce RTX 4050 Mobile just 0.1% behind.

The disparity between component percentiles creates an interesting dynamic: the GPU is clearly the stronger half of this pairing, yet the CPU's lower standing limits the combo's overall rank. In Minecraft specifically, this imbalance matters less than in CPU-bound titles, as the measured frame rates show the system delivering playable results even at 4K Ultra. The data indicates that while this combo won't compete with top-tier rigs, it offers a balanced experience where neither component becomes an obvious bottleneck at common gaming resolutions.

GPU Role

The AMD Radeon RX 6600 brings 8 GB of GDDR6 memory on a 128-bit bus, yielding 224.0 GB/s of bandwidth—sufficient for Minecraft's texture-heavy workloads at high resolutions. Its clock speeds are aggressive: a base of 1626 MHz, a game clock of 2044 MHz, and a boost of 2491 MHz, paired with 1792 shading units and 64 ROPs. These specifications translate to a pixel rate of 159.4 GPixel/s and a texture rate of 279.0 GTexel/s, which explains why the card delivers 356 FPS at 1080p Low and still manages 74 FPS at 4K High.

The GPU's benchmark results reinforce its mid-range positioning: a Passmark G3D score of 15,096 and a Geekbench OpenCL score of 28,850 demonstrate solid compute capability. The 3DMark Steel Nomad DX12 score of 1,492 shows modern API proficiency, while the Vulkan score of 67,623 suggests excellent driver-level optimization for games that support it. Minecraft's Java-based rendering does not heavily leverage these advanced APIs, but the raw fill rate and memory bandwidth ensure the RX 6600 handles the game's block-based geometry with ease, even at 4K resolutions where pixel throughput becomes critical.

Resolution Scaling

The FPS scaling across resolutions reveals a system that remains GPU-bound at higher settings but becomes increasingly CPU-limited at lower settings. At 1080p Low, the combo achieves 356 FPS; moving to 1440p Low drops this to 225 FPS (a 37% reduction), and 4K Low yields 118 FPS (a 67% reduction from 1080p). This steep decline at Low settings suggests the CPU can feed frames quickly at lower resolutions, but the GPU's workload grows substantially as resolution increases.

At High settings, the pattern shifts: 1080p delivers 224 FPS, 1440p delivers 141 FPS (37% lower), and 4K delivers 74 FPS (67% lower). The proportional drops are nearly identical to Low settings, indicating consistent GPU scaling. However, at Ultra settings, the scaling becomes more severe: 1080p Ultra produces 140 FPS, 1440p Ultra drops to 88 FPS (37% lower), and 4K Ultra falls to 46 FPS (67% lower). This consistency across all settings suggests the limiting factor is the GPU's pixel throughput rather than CPU overhead, as the percentage drops remain uniform regardless of which settings preset is active.

The 4K Ultra result of 46 FPS is the only measured point below 60 FPS, marking the boundary where this combo ceases to deliver smooth gameplay. The 4K Medium result of 93 FPS with a minimum of 79 FPS shows that dropping from Ultra to Medium recovers more than double the frame rate, indicating that Ultra settings impose a rendering cost disproportionate to their visual benefit on this hardware.

A: At 1080p Low, the combo achieves 356 FPS, and Medium settings still deliver 282 FPS with a minimum of 240 FPS. These frame rates far exceed the refresh rates of most monitors, ensuring no display-side bottleneck for competitive gameplay.

Settings Recommendations

The measured data clearly indicates that Ultra settings are unnecessary for this hardware in Minecraft. At 1080p, Ultra produces 140 FPS, but dropping to High only loses 60 FPS while offering nearly identical visual quality for most players—the 224 FPS at High is more than sufficient for any display. At 1440p, High delivers 141 FPS, which is ideal for high-refresh monitors, whereas Ultra drops to 88 FPS, a significant reduction for marginal visual gains.

For 4K users, Medium is the recommended preset: 93 FPS average with a minimum of 79 FPS ensures a consistently smooth experience, while High drops to 74 FPS and Ultra falls below playable thresholds at 46 FPS. The Medium preset at 4K also shows a maximum of 107 FPS, indicating headroom for occasional scene complexity. At 1080p and 1440p, High settings provide the best experience, as the jump from Medium to High costs only 58 FPS at 1080p (282 to 224) and 37 FPS at 1440p (178 to 141), while the visual upgrade in draw distance and texture filtering is noticeable.

The Low preset is only recommended for extreme competitive play where maximum frame rates matter—356 FPS at 1080p Low and 225 FPS at 1440p Low—but the visual compromise is substantial for a game where aesthetics are a core appeal. The data suggests that this combo's sweet spot is 1440p High, offering 141 FPS with a balanced load on both components.

CPU Role

The Intel Core i5-9400 contributes six cores and six threads, clocked at a base of 2.90 GHz and a boost of 4.10 GHz, with 9 MB of shared L3 cache. Its average benchmark score of 2,254 places it in the 47th percentile of all CPUs, with a Cinebench R23 multi-core score of 6,629 and single-core score of 935. These scores indicate modest multi-threaded capability, but Minecraft's Java engine is notoriously single-threaded, which explains why the CPU's single-core performance—a Geekbench single-core score of 1,389—matters more than its multi-core throughput.

The CPU's 47th percentile ranking is reflected in its nearest rivals: the Intel Core i7-1068NG7 scores 2,259 (0.2% faster), the Intel Core i3-10305 scores 2,264 (0.4% faster), while the Intel Core i7-10710U scores 2,248 (0.3% slower) and the AMD Ryzen 5 PRO 1500 scores 2,246 (0.4% slower). This clustering shows the i5-9400 sits in a tightly packed group of mid-range processors, none of which would dramatically change Minecraft's performance.

In practice, the CPU's role is to feed the RX 6600 with draw calls and physics calculations. The measured 356 FPS at 1080p Low demonstrates that the six Coffee Lake cores handle Minecraft's world generation and entity updates without bottlenecking the GPU. However, the 67% FPS drop from 1080p to 4K across all settings indicates that as resolution increases, the GPU becomes the limiting factor, meaning the CPU's modest 47th percentile standing does not hinder performance at higher resolutions. The 65W TDP and 14nm process node show this is an efficient, older-generation part, but its six cores at 4.10 GHz boost provide adequate headroom for Minecraft's demands.
