Minecraft

Minecraft’s performance on the Intel Core i5-9400 with the NVIDIA GeForce RTX 3050 4 GB reveals a system that scales predictably with resolution, though the bottlenecks shift dramatically depending on the settings preset. The measured data shows a clear narrative: at lower resolutions, the CPU takes the lead, while at 4K, the GPU’s memory and bandwidth constraints become the primary limiter, particularly on the highest presets.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep but not uniform across settings, indicating where the system’s pressure points lie. At Low settings, the average FPS falls from 275 at 1920x1080 to 174 at 2560x1440, a reduction of roughly 37%, and then to 91 at 3840x2160, a further 48% drop. This scaling suggests that even at the lowest quality, the RTX 3050 4 GB is not fully saturated at 1080p, allowing the CPU to push high frame rates, but the GPU begins to struggle as pixel count increases.

The Medium preset tells a similar story, with averages of 218 at 1080p, 138 at 1440p, and 72 at 4K. The gap between 1080p and 1440p here is 80 FPS, while the gap between 1440p and 4K is 66 FPS, showing a slightly more linear decline. However, the High preset reveals a more pronounced cliff: 173 FPS at 1080p, 109 at 1440p, and just 57 at 4K. The percentage drop from 1440p to 4K is about 48%, which is consistent with the Low preset, but the absolute numbers are much lower, hinting that the GPU’s 4 GB memory capacity is becoming a factor at higher detail levels.

The Ultra preset shows the most severe scaling, with averages of 108 at 1080p, 68 at 1440p, and 36 at 4K. The drop from 1440p to 4K is 47%, but the absolute 4K result of 36 FPS is barely playable. This pattern indicates that at Ultra, the combination of high texture detail and shading demands exceeds what the 4 GB frame buffer can efficiently handle at 4K, causing a disproportionate performance penalty compared to lower settings. The data suggests that while the GPU is the limiting component at 4K across all presets, its weakness is amplified when memory pressure is highest, leading to the sub-60 FPS result at Ultra.

GPU Role

The NVIDIA GeForce RTX 3050 4 GB is built on the Ampere architecture with a GA107 chip, fabricated on Samsung’s 8 nm process. It features a base clock of 1545 MHz and a boost clock of 1740 MHz, with 2048 shading units, 64 TMUs, and 32 ROPs. The memory configuration is a critical factor: 4 GB of GDDR6 on a 128-bit bus, providing 192.0 GB/s of bandwidth. This bandwidth is modest by modern standards, and the benchmark results reflect its limitations in Minecraft’s higher presets.

At 1080p Low, the GPU achieves 275 FPS, which is far beyond what the display can likely show, but as resolution increases, the pixel rate and texture rate become more demanding. The GPU’s pixel rate is 55.68 GPixel/s and texture rate is 111.4 GTexel/s, which are adequate for 1080p but insufficient for 4K at high detail. The FP32 performance of 7.127 TFLOPS is solid for a card in this class, yet the memory bandwidth of 192.0 GB/s is the likely bottleneck at 4K, especially when the Medium preset’s 4K result (72 FPS) is compared to the High preset’s 4K result (57 FPS). The 4 GB capacity also comes into play; at Ultra 4K, the 36 FPS average suggests the card is thrashing or running out of memory for textures, leading to severe frame drops.

The card’s 16 RT cores and 64 tensor cores are present but irrelevant for Minecraft’s standard rendering, meaning the raw rasterization performance is what matters. The data shows that the RTX 3050 4 GB is capable of high refresh rates at 1080p on Medium and High, but it is not a 4K card for this game unless the user accepts Low settings, where it still only manages 91 FPS. The 90 W TDP and 250 W suggested PSU indicate a power-efficient design, but that efficiency does not translate to high-end performance at extreme resolutions.

Settings Recommendations

Based on the measured rows, the optimal balance between visual quality and frame rate is achieved at Medium settings for most resolutions. At 1920x1080, Medium delivers 218 FPS average, with a minimum of 185 and maximum of 251, which is smooth and responsive. Moving to High at 1080p yields 173 FPS, a 45 FPS reduction for a marginal visual improvement, making Medium the better choice for high-refresh monitors. At 2560x1440, Medium hits 138 FPS, which is still excellent for competitive play, while High drops to 109 FPS, still playable but with less headroom.

For 4K, the recommendations shift. Medium at 3840x2160 produces 72 FPS, which is acceptable for a slower-paced game, but High drops to 57 FPS, which may feel inconsistent. Low at 4K gives 91 FPS, which is the only preset that provides a comfortable margin, but it sacrifices visual fidelity. The Ultra preset is not recommended at any resolution above 1080p, as it produces 108 FPS at 1080p but only 68 FPS at 1440p and 36 FPS at 4K, making it only viable for 1080p gaming. The data suggests that Medium is the sweet spot for this combo, offering the best experience across all three resolutions without hitting the GPU’s memory ceiling.

Measured FPS Breakdown

At 1920x1080, the full range of presets is as follows: Low averages 275 FPS, Medium averages 218 FPS with a minimum of 185 and maximum of 251, High averages 173 FPS, and Ultra averages 108 FPS. The progression shows a consistent reduction of roughly 45-55 FPS per step from Low to Medium to High, but the jump from High to Ultra is 65 FPS, indicating a heavier cost for the highest settings.

At 2560x1440, the numbers are: Low at 174 FPS, Medium at 138 FPS (117 min, 158 max), High at 109 FPS, and Ultra at 68 FPS. The delta between Low and Medium is 36 FPS, Medium to High is 29 FPS, and High to Ultra is 41 FPS. The Ultra penalty is proportionally larger here, suggesting the GPU is working harder to fill the extra pixels with advanced effects.

At 3840x2160, the results are: Low at 91 FPS, Medium at 72 FPS (61 min, 83 max), High at 57 FPS, and Ultra at 36 FPS. The Low to Medium drop is 19 FPS, Medium to High is 15 FPS, and High to Ultra is 21 FPS. The minimum frame rates at Medium and the overall averages indicate that 4K is borderline for this GPU, with only Low and Medium providing playable experiences. The Ultra result of 36 FPS is below the threshold for smooth gameplay, confirming that this resolution is not intended for the highest quality settings on this hardware.

FAQ

A: The RTX 3050 4 GB has a memory bandwidth of 192.0 GB/s and a 128-bit bus. The benchmark results show that at 4K Ultra, the average FPS falls to 36, which is likely due to the limited bandwidth and 4 GB capacity struggling to handle the high-resolution textures and shading data.

CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor based on the Coffee Lake architecture, manufactured on a 14 nm process. It has a base clock of 2.90 GHz and a boost clock of 4.10 GHz, with a 9 MB shared L3 cache. Its memory support is DDR4 with a dual-channel bus, providing 42.7 GB/s of bandwidth. In the benchmark database, this CPU scores 6629 in Cinebench R23 multi-core and 935 in single-core, with a Geekbench multi-core score of 5141 and single-core of 1389. These scores place it in the 47th percentile of all CPUs, and its average benchmark score is 2254.

The CPU’s nearest rivals include the Intel Core i7-1068NG7 with an average score of 2259 (a 0.2% difference), the Intel Core i7-10710U with 2248 (0.3% difference), the AMD Ryzen 5 PRO 1500 with 2246 (0.4% difference), and the Intel Core i3-10305 with 2264 (0.4% difference). This indicates that the i5-9400 is competitive with these parts, but its lack of hyper-threading limits its multi-threaded potential compared to some newer designs.

In Minecraft, the CPU’s role is most evident at lower resolutions. At 1080p Low, the system achieves 275 FPS, which is likely near the CPU’s limit for this game, as the GPU is not heavily taxed at that resolution. The 4.10 GHz boost clock provides strong single-thread performance, which is crucial for Minecraft’s main game loop. However, as resolution increases to 1440p and 4K, the frame rates drop significantly, showing that the GPU becomes the limiting factor. The CPU’s 6 threads are sufficient for Minecraft’s workload, and the data does not show any CPU-related stutters, as the minimum frame rates at Medium settings are relatively close to the averages. The processor’s 65 W TDP and Socket 1151 compatibility make it a standard desktop part, and its performance in this game is adequate, though not exceptional, as evidenced by its 47th percentile ranking.
