Minecraft

Minecraft with the Intel Core i5-9400 and AMD Radeon RX 9070 produces a performance profile that is heavily dictated by resolution and settings, with the CPU becoming the primary limiting factor at lower resolutions. The data shows a combo that ranks in the 65.7th percentile of all tested combinations, demonstrating strong but not top-tier capability in this sandbox title.

Resolution Scaling

The performance delta between 1080p and 4K reveals a classic shift in bottleneck behavior. At 1920x1080 with High settings, the combo delivers 377 FPS, which drops to 238 FPS at 2560x1440 (a 36.9% reduction) and then to 124 FPS at 3840x2160 (a 67.1% reduction from the 1080p baseline). This steep decline as resolution increases indicates that the GPU is progressively taking on more work, but the relatively modest absolute FPS at 1080p suggests the CPU is holding the system back from fully exploiting the RX 9070's potential.

The scaling pattern becomes more pronounced when examining the Low settings tier. The 1920x1080 Low result is 455 FPS, which falls to 379 FPS at 1440p (a 16.7% drop) and 198 FPS at 4K (a 56.5% drop from 1080p). The smaller relative decline between 1080p and 1440p at Low settings compared to High settings (16.7% versus 36.9%) indicates that the CPU is the primary constraint at lower graphical loads. When the GPU has less work to do, the i5-9400's six threads become the ceiling, preventing the frame rate from scaling as high as the GPU alone could achieve.

At Ultra settings, the trend reverses somewhat. The 1080p Ultra score of 236 FPS drops to 149 FPS at 1440p (a 36.9% reduction) and 78 FPS at 4K (a 66.9% reduction from 1080p). This near-identical percentage scaling to the High tier suggests that once the graphical load becomes substantial, the GPU takes over as the dominant factor. The fact that Ultra at 1080p (236 FPS) is lower than High at 1080p (377 FPS) demonstrates that the additional graphical effects are demanding enough to shift the balance toward GPU limitation.

The Medium settings tier provides the clearest picture of the system's behavior. At 1920x1080 Medium, the combo hits 418 FPS with a minimum of 356 FPS and maximum of 481 FPS. Moving to 1440p Medium yields 300 FPS (a 28.2% drop) with a 255-345 FPS range. At 4K Medium, the average falls to 157 FPS with a 133-180 FPS range. The frame time consistency, as indicated by the min-max spread, remains relatively stable across resolutions, suggesting that the i5-9400's six cores provide a consistent baseline even when the GPU load varies significantly.

GPU Role

The AMD Radeon RX 9070 brings substantial graphics horsepower to this pairing, with 16 GB of GDDR6 memory on a 256-bit bus delivering 644.6 GB/s of bandwidth. This memory configuration is crucial for Minecraft, where large texture packs and draw distances can quickly consume video memory. The GPU's clock behavior, with a base of 1330 MHz, a game clock of 2070 MHz, and a boost of 2520 MHz, indicates that the card is designed to sustain high performance under sustained loads.

The RX 9070's 3584 shading units, 224 texture mapping units, and 128 render output units provide the raw throughput necessary for high-resolution rendering. The measured FPS data shows that the GPU is capable of pushing 124 FPS at 4K High settings, which is a demanding workload for any graphics card. The fact that 4K Ultra drops to 78 FPS — nearly half of the High result — demonstrates that the Ultra preset introduces effects that heavily tax the GPU's compute resources.

The GPU's 56 ray tracing cores are present but Minecraft's traditional rendering path does not heavily utilize them in these measurements. The 36.13 TFLOPS of FP32 performance and 322.6 GPixel/s pixel rate give the card ample headroom for the game's block-based geometry, which often involves simple but numerous draw calls. The 564.5 GTexel/s texture rate ensures that the game's procedural textures can be applied quickly, though the CPU must supply the draw call stream.

The RX 9070's benchmark results place it in the 69th percentile of all GPUs, with an average benchmark score of 23877. Its nearest rival, the NVIDIA GeForce RTX 2080 SUPER, scores 24170, putting the RX 9070 1.2% behind. This relative standing suggests that while the GPU is strong, it is not at the absolute top tier, which aligns with its measured performance in Minecraft where CPU limitations often cap the frame rate.

How This Combo Ranks

The combination of the Intel Core i5-9400 and AMD Radeon RX 9070 ranks 1272 out of 3710 tested combos in Minecraft, placing it in the 65.7th percentile. This ranking reflects a system that is capable of high frame rates but is not optimized for absolute maximum performance in this title. The ranking position suggests that many combinations with newer or higher-core-count CPUs achieve better results, particularly at lower resolutions where the CPU becomes the bottleneck.

The i5-9400's individual standing helps explain this ranking. The CPU sits in the 47th percentile of all CPUs with an average benchmark score of 2254. Its nearest rivals include the Intel Core i7-10710U (0.3% faster), AMD Ryzen 5 PRO 1500 (0.4% faster), and Intel Core i3-10305 (0.4% slower). This clustering around the 2250-2260 score range indicates that the i5-9400 is firmly in the mid-range tier, neither excelling nor lagging significantly in raw compute capability.

The GPU's higher percentile (69th) compared to the CPU (47th) creates an imbalance that is evident in the measured FPS data. In scenarios where the GPU is fully utilized, such as 4K Ultra, the system performs respectably relative to its ranking. However, in CPU-limited scenarios like 1080p Low, the combo's ranking likely suffers because the RX 9070 cannot stretch its legs. The combo rank of 1272 suggests that while this pairing is solid, users seeking top-tier Minecraft performance would need a more powerful CPU to complement the GPU.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. The Low preset achieves 455 FPS, which is the maximum average recorded in this data set. Medium settings produce 418 FPS with a minimum of 356 FPS and maximum of 481 FPS, showing that the frame rate remains high even with moderate graphical effects. High settings drop to 377 FPS, while Ultra settings yield 236 FPS. The gap between High and Ultra at 1080p (141 FPS) is larger than the gap between Low and Medium (37 FPS), indicating that the Ultra preset introduces significant GPU workload.

At 2560x1440, the frame rates remain highly playable but show the expected decline. Low settings produce 379 FPS, which is still exceptionally high for a 1440p resolution. Medium settings deliver 300 FPS with a 255-345 FPS range, maintaining smooth performance. High settings drop to 238 FPS, and Ultra settings fall to 149 FPS. The 1440p Ultra result of 149 FPS is still well above the 60 FPS threshold, making this resolution viable for the most demanding settings.

At 3840x2160, the system begins to show its limitations. Low settings produce 198 FPS, which is still very playable. Medium settings deliver 157 FPS with a 133-180 FPS range, maintaining good consistency. High settings drop to 124 FPS, which remains smooth for most displays. Ultra settings fall to 78 FPS, which is below the 144 Hz refresh rate that this GPU might otherwise support at lower resolutions. The 4K Ultra minimum frame rate is not recorded, but the average of 78 FPS suggests that some scenes may dip below 60 FPS, making this setting combination the most demanding scenario in the data.

The progression from 1080p Low (455 FPS) to 4K Ultra (78 FPS) represents an 82.9% reduction in frame rate, which is substantial but not unexpected for a game with Minecraft's rendering characteristics. The stepwise reductions — from Low to Medium to High to Ultra — are consistent across resolutions, with Ultra settings consistently costing roughly 40-50% of the frame rate compared to Low settings at the same resolution.

CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor based on the Coffee Lake architecture, manufactured on Intel's 14 nm process. It operates at a base clock of 2.90 GHz with a boost clock of 4.10 GHz, and its 65 W TDP indicates a modest power envelope. The CPU's cache configuration includes 64 KB of L1 per core, 256 KB of L2 per core, and 9 MB of shared L3 cache, which is shared across all six cores.

In Minecraft, the CPU's role is critical because the game's world generation and entity processing are heavily single-threaded. The i5-9400's single-core performance, as measured by its Cinebench R23 single-core score of 935, is adequate but not exceptional. This explains why the frame rates at 1080p Low (455 FPS) do not scale as high as one might expect from a GPU with 36.13 TFLOPS of compute power. The CPU's six threads provide some multi-threading capability, but the game's primary simulation thread will often become the limiting factor.

The CPU's memory support for DDR4 with dual-channel configuration provides 42.7 GB/s of bandwidth, which is sufficient for Minecraft's needs but does not offer the high-bandwidth advantages of newer platforms. The PCIe Gen 3 interface with 16 lanes is adequate for the RX 9070, though the GPU is designed for PCIe 5.0 x16. This generational mismatch could slightly limit data transfer rates, though the impact on frame rates in Minecraft is likely minimal given the game's relatively low data throughput requirements.

The i5-9400's benchmark scores paint a picture of a mid-range processor. Its Cinebench R23 multi-core score of 6629 and Geekbench multi-core score of 5141 place it in the 47th percentile of all CPUs. The nearest rival, the Intel Core i7-1068NG7, scores 2259 on average, which is 0.2% higher. This tight clustering indicates that the i5-9400 is competitive with other mid-range options but does not offer any significant advantage in compute-heavy workloads. In Minecraft specifically, the CPU's modest single-thread performance means that the RX 9070's impressive specs are often underutilized, particularly at lower resolutions where the CPU must feed the GPU with draw calls at very high rates.
