Minecraft

The Intel Core i5-9400 paired with the Intel Arc B390 presents a unique case in Minecraft, where the integrated graphics solution is the primary rendering engine. The measured frame rates reveal a system that is heavily dependent on resolution and settings, with the GPU acting as the definitive bottleneck at higher loads. The data indicates that this combo is positioned in the lower tier of tested configurations, ranking 984th out of 1176 combos, but it still offers playable performance at specific settings, particularly at 1080p.

Resolution Scaling

The performance drop from 1080p to 4K is steep and consistent across all settings, clearly identifying the Intel Arc B390 as the limiting factor. At Low settings, the average frame rate falls from 216 FPS at 1920x1080 to 136 FPS at 2560x1440, a significant 37% reduction, and then further down to 71 FPS at 3840x2160. This pattern shows that even at the lowest graphical load, the GPU's rendering capabilities are taxed heavily as pixel count increases.

The scaling becomes even more pronounced at higher settings. With High settings, the average FPS drops from 136 at 1080p to 86 at 1440p, and then plummets to 45 at 4K. This represents a 67% decrease from 1080p to 4K, indicating that the GPU is not just pixel-bound but also shader-bound. The Ultra preset shows the most dramatic falloff, with averages of 85 FPS at 1080p, 54 FPS at 1440p, and just 28 FPS at 4K. This last figure is below the threshold for smooth gameplay, suggesting that 4K Ultra is not a viable option for this hardware.

The data suggests that the Core i5-9400, with its six cores and six threads, is not the primary constraint in this scenario. If the CPU were the bottleneck, we would expect to see less variation between resolutions, as the CPU workload would remain relatively constant. Instead, the consistent and substantial FPS drops with each resolution increase point directly to the Arc B390's limited fillrate and compute capacity. The GPU's 60.00 GPixel/s pixel rate and 120.0 GTexel/s texture rate are simply insufficient for the demands of 4K rendering in Minecraft, especially with higher quality settings.

FAQ

Q: What is the best resolution to play Minecraft with this combo for a smooth experience?

A: The data shows that 1920x1080 is the only resolution where all settings presets maintain an average above 60 FPS. At this resolution, even the demanding Ultra preset achieves 85 FPS, while Medium and High reach 171 and 136 FPS respectively.

Q: How does the Intel Arc B390 compare to its closest rivals in terms of raw GPU score?

A: At 2560x1440, the Low preset averages 136 FPS, while the Ultra preset averages 54 FPS. This is a substantial 82 FPS difference, showing that the Ultra preset imposes a heavy load on the integrated GPU, reducing performance by over 60% compared to Low.

Q: What are the specifications of the CPU that influence its performance in Minecraft?

A: The Intel Core i5-9400 features 6 cores and 6 threads, with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. It has a 9 MB shared L3 cache. This configuration is typical for a mid-range desktop processor from the Coffee Lake generation.

How This Combo Ranks

The combination of the Intel Core i5-9400 and Intel Arc B390 ranks 984th out of 1176 tested combos in Minecraft. This places it in the lower 16% of all configurations, indicating that it is a low-performance pairing for this specific game. The ranking is heavily influenced by the GPU, which itself is in the 9th percentile of all GPUs, a very low standing.

The CPU's performance, on the other hand, is more respectable. Being in the 47th percentile of all CPUs, the i5-9400 is a competent mid-range processor. However, its potential is severely capped by the Arc B390's limited rendering power. The benchmark results suggest that this combo is not designed for high-end gaming, but rather for basic, low-load scenarios. In the context of all tested combos, this system is clearly at the lower end of the spectrum, and users should temper their expectations accordingly. The data indicates that while the CPU is a balanced performer, the GPU drags the entire combo down to a rank that is near the bottom.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo's capabilities across three resolutions and four settings presets.

At 1920x1080:

• Low: Average 216 FPS. This is the highest score recorded for this combo, indicating that the CPU is capable of feeding frames quickly when the GPU load is minimal.
• Medium: Average 171 FPS, with a minimum of 146 FPS and a maximum of 197 FPS. This shows a stable performance window with no major dips.
• High: Average 136 FPS. This is a solid result, offering smooth gameplay with room to spare on most displays.
• Ultra: Average 85 FPS. This is still above 60 FPS, providing a playable experience with high visual fidelity.

At 2560x1440:

• Low: Average 136 FPS. This is identical to the 1080p High result, showing the resolution's impact on the GPU.
• Medium: Average 108 FPS, with a minimum of 92 FPS and a maximum of 124 FPS. The minimum is still well above 60 FPS, ensuring a smooth experience.
• High: Average 86 FPS. This remains a playable frame rate, though it is noticeably lower than the 1080p result.
• Ultra: Average 54 FPS. This drops below the 60 FPS threshold, making it less ideal for fast-paced action.

At 3840x2160:

• Low: Average 71 FPS. This is the only 4K preset that maintains an average above 60 FPS.
• Medium: Average 56 FPS, with a minimum of 48 FPS and a maximum of 65 FPS. The minimum is below 60 FPS, indicating potential stutters in busy scenes.
• High: Average 45 FPS. This is below the smoothness threshold and is best avoided.
• Ultra: Average 28 FPS. This is largely unplayable, as the frame rate is too low for responsive gameplay.

CPU Role

The Intel Core i5-9400 plays a secondary role in this combo's Minecraft performance. With 6 cores and 6 threads, it lacks the hyper-threading of some rivals, but its base clock of 2.90 GHz and boost clock of 4.10 GHz provide adequate single-threaded performance for the game's primary logic thread. The 9 MB of shared L3 cache is sufficient for the game's data needs.

Benchmark results show the i5-9400 achieves a Cinebench R23 multi-core score of 6629 and a single-core score of 935. Its Geekbench scores are 5141 for multi-core and 1389 for single-core. These figures place it in the 47th percentile of all CPUs, with an average benchmark score of 2254. Its nearest rival, the Intel Core i7-1068NG7, scores 2259, a difference of just 0.2%, indicating that the i5-9400 is a typical performer in its class.

In Minecraft, the CPU's role is to handle game logic, chunk loading, and entity updates. The data shows that at 1080p Low settings, the system achieves 216 FPS, suggesting that the CPU is not a bottleneck at this point. However, as the resolution increases and the GPU load grows, the FPS drops, confirming that the GPU is the limiting component. The CPU has enough headroom to push higher frame rates, but it is held back by the Arc B390's inability to render frames fast enough. Therefore, the i5-9400 is not the weak link; it is a capable processor that is constrained by its integrated graphics counterpart.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the user's target resolution and desired frame rate.

For 1080p, the Ultra preset is the best choice for visual quality, as it still averages 85 FPS. This provides a high-fidelity experience without sacrificing smoothness. If a user prefers maximum performance, the Low preset at 216 FPS offers an incredibly fluid experience, though it sacrifices most graphical features. The Medium preset at 171 FPS is a good balance, and the High preset at 136 FPS is also a strong option.

For 1440p, the High preset at 86 FPS is the recommended sweet spot. It delivers good visual quality while maintaining a frame rate that is suitable for most monitors. The Medium preset at 108 FPS is also a valid choice, offering a higher frame rate with a slight reduction in quality. The Low preset at 136 FPS is ideal for competitive play, while the Ultra preset at 54 FPS is not recommended as it falls below 60 FPS.

For 4K, the options are limited. The Low preset at 71 FPS is the only one that provides a consistently smooth experience. The Medium preset at 56 FPS is playable but may have occasional dips to 48 FPS. The High and Ultra presets at 45 FPS and 28 FPS respectively are not recommended for a satisfactory gaming experience. Therefore, at 4K, users should stick to Low settings to maintain playability. The data suggests that this combo is best utilized at 1080p, where it can handle even the most demanding preset with ease, or at 1440p with High settings for a balanced experience.
