Minecraft

Minecraft with the Intel Core i5-12400 and Intel Arc B390 produces a playable experience, but the data reveals a configuration that is heavily constrained by the graphics processor. The measured frame rates indicate that the Arc B390 is the primary bottleneck, limiting performance across all resolutions and settings. The best experience balances visual fidelity with consistent frame pacing, which is achieved at Medium settings, where the data shows the most stable performance metrics.

Settings Recommendations

The benchmark data for this combination shows a clear hierarchy across the four tested presets: Low, Medium, High, and Ultra. At 1920x1080, the Low preset delivers an average of 216 FPS, which is exceptionally high but comes with significant visual compromises. The Ultra preset, conversely, provides the highest visual quality but drops the average to 85 FPS at the same resolution. The sweet spot is the Medium preset, which yields 171 FPS at 1080p with a minimum of 146 FPS and a maximum of 197 FPS. This frame time consistency is critical for a game like Minecraft, where sudden frame drops can be jarring during world generation or chunk loading.

Moving to 2560x1440, the pattern continues. Low delivers 136 FPS, Medium delivers 108 FPS, and High delivers 86 FPS. The Ultra preset falls to 54 FPS, which is approaching the threshold where responsiveness can suffer. At 3840x2160, the situation becomes more constrained: Low averages 71 FPS, Medium averages 56 FPS, High averages 45 FPS, and Ultra drops to 28 FPS.

The data suggests that Medium is the optimal preset for this hardware combination. At 1080p, the 171 FPS average with a 146 FPS minimum provides a large margin above typical display refresh rates, ensuring smooth gameplay even in complex scenes. At 1440p, the 108 FPS average with a 92 FPS minimum remains fluid. The Medium preset also shows the only complete set of min/max data across all resolutions, which indicates the test methodology captured consistent frame delivery. High settings are viable at 1080p (136 FPS) and 1440p (86 FPS), but the lack of min/max data for High makes it harder to recommend over Medium, which has documented stability. Low settings are unnecessary at 1080p given the headroom, and Ultra should be avoided at all resolutions due to the significant performance penalty, particularly the 28 FPS result at 4K.

FAQ

A: The highest measured average frame rate at 1920x1080 is 216 FPS, achieved with the Low preset. The Medium preset delivers 171 FPS, High delivers 136 FPS, and Ultra delivers 85 FPS.

Q: Is the Intel Core i5-12400 or the Intel Arc B390 the limiting factor in this configuration?

A: The GPU is clearly the limiting factor. The Arc B390 has a percentile rank of 9 among all GPUs, while the i5-12400 ranks in the 72nd percentile among CPUs. The GPU's nearest rivals include the NVIDIA GeForce GT 710 and GT 625 OEM, which are entry-level parts, whereas the CPU's rivals include the AMD EPYC 7643 and Intel Core i7-1355U, which are far more capable. The frame rate scaling with resolution confirms this GPU-bound scenario.

Q: How does the performance at 1440p compare to 1080p for the Medium preset?

A: At 1920x1080, the Medium preset averages 171 FPS. At 2560x1440, the same preset averages 108 FPS. This represents a drop of 63 FPS, or approximately 37% lower performance when moving from 1080p to 1440p.

Q: What is the combo's ranking among all tested CPU and GPU combinations for Minecraft?

A: This specific combination of Intel Core i5-12400 and Intel Arc B390 ranks 984th out of 1176 tested combos in Minecraft. This places it in the lower percentile of tested configurations, consistent with the weak GPU.

Q: Can this hardware run Minecraft at 4K with acceptable performance?

A: At 3840x2160, the Medium preset averages 56 FPS with a minimum of 48 FPS and a maximum of 65 FPS. This is playable but not ideal. The High preset drops to 45 FPS, and Ultra falls to 28 FPS. For a smoother 4K experience, the Low preset at 71 FPS is the most viable option.

Q: Does the Ultra preset provide any benefit at 1080p?

A: The Ultra preset at 1080p averages 85 FPS. While this is above the 60 FPS threshold, it is less than half the frame rate of the Medium preset (171 FPS). Given the significant performance cost, Ultra is not recommended when Medium provides a higher and more stable frame rate.

GPU Role

The Intel Arc B390 is the decisive component in this configuration, and its specifications reveal why it struggles in Minecraft. The GPU is based on the Xe3-LPG architecture on a 3 nm process node. It features 1536 shading units, 48 texture mapping units, and 24 raster output units, along with 12 ray tracing cores. The base clock is 300 MHz, with a boost clock of 2500 MHz. The memory configuration is marked as "System Shared," meaning it relies on shared system memory rather than dedicated VRAM. This is a critical limitation, as the memory bandwidth is listed as "System Dependent."

The benchmark data for the GPU shows a single 3DMark Steel Nomad DX12 score of 1482. Its percentile rank among all GPUs is just 9, placing it in the bottom decile of performance. The nearest rivals are the NVIDIA GeForce GT 520MX (score 1463, delta 1.3%), NVIDIA GeForce 800M (score 1460, delta 1.5%), NVIDIA GeForce GT 625 OEM (score 1446, delta 2.5%), and NVIDIA GeForce GT 710 (score 1443, delta 2.7%). These are all legacy or entry-level parts, which contextualizes the Arc B390's position. It is not a gaming-oriented discrete GPU; it is an integrated graphics processor (IGP) with a 80 W TDP, explaining the modest pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s.

In Minecraft, which can be sensitive to fill rate and memory bandwidth, the Arc B390's limitations are exposed. The shared memory architecture means the GPU competes with the CPU for memory bandwidth, which becomes more problematic at higher resolutions and settings. The data supports this: at 1080p Low, the GPU can render 216 FPS, but at 4K Ultra, it falls to 28 FPS. The 7.680 TFLOPS of FP32 compute is sufficient for simple scenes, but the system-dependent memory bandwidth creates a bottleneck when pixel count increases. The 12 RT cores are irrelevant for Minecraft's default rendering path, and the 24 ROPs limit the pixel throughput at high resolutions.

How This Combo Ranks

The combination of the Intel Core i5-12400 and Intel Arc B390 ranks 984th out of 1176 tested combos in Minecraft. This places the configuration in the lower 16% of all tested pairings. The ranking reflects the substantial imbalance between the CPU and GPU. The i5-12400 is a capable six-core, 12-thread processor based on Alder Lake architecture. Its benchmark scores are strong: a Cinebench R23 multi-core score of 15989, a Geekbench multi-core score of 8564, and a Passmark multi-thread score of 18747. It ranks in the 72nd percentile among all CPUs, with an average benchmark score of 18683. Its nearest CPU rivals include the AMD EPYC 7643 (score 18697, delta -0.1%), Intel Core i7-1355U (score 18730, delta -0.3%), AMD Ryzen AI 5 330 (score 18811, delta -0.7%), and Intel Core i3-14100F (score 18519, delta 0.9%).

In contrast, the GPU's 9th percentile ranking drags the entire combo down. The CPU is capable of feeding the GPU far more frames than the Arc B390 can render, especially at higher resolutions. The data shows that at 1080p Low, the combo hits 216 FPS, but this is likely CPU-limited at that point. As resolution increases, the GPU becomes the sole bottleneck. The 984th rank out of 1176 combos indicates that most other tested configurations, even those with weaker CPUs, outperform this pairing because they have more capable GPUs. The delta between the CPU and GPU percentiles is stark, and the in-game result is a system that leaves significant CPU performance on the table.

Resolution Scaling

The frame rate scaling across resolutions provides clear evidence of the GPU bottleneck. At 1080p Medium, the average FPS is 171. At 1440p Medium, it drops to 108 FPS, a reduction of 63 FPS (about 37%). At 4K Medium, it drops to 56 FPS, a further reduction of 52 FPS (about 48% from 1440p). This pattern is consistent across all settings. For example, at High settings, the progression is 136 FPS (1080p) → 86 FPS (1440p) → 45 FPS (4K). At Low settings, it is 216 FPS → 136 FPS → 71 FPS.

The percentage drops are not linear, which is typical of a GPU-bound scenario. When moving from 1080p to 1440p, the pixel count increases by 78%, and the FPS drops by 37% at Medium. Moving from 1440p to 4K increases the pixel count by 125%, and the FPS drops by 48% at Medium. The fact that the FPS does not halve when pixel count more than doubles suggests that the CPU is still contributing some overhead at lower resolutions. However, at 4K, the GPU is fully saturated, and the frame rates become critically low. The difference between 1080p and 4K at Ultra settings is particularly telling: 85 FPS versus 28 FPS, a 67% reduction.

This scaling pattern indicates that the limiting component is the GPU. A CPU-bound system would show relatively flat FPS across resolutions, as the CPU's workload does not scale with pixel count. Here, the FPS drops dramatically with resolution, confirming that the Arc B390's rendering capabilities are the primary constraint. The system-dependent memory bandwidth of the GPU exacerbates this, as higher resolutions require more memory bandwidth, which is shared with the CPU.

Measured FPS Breakdown

The complete measured FPS data for this configuration is as follows:

1920x1080:

• Low: Average 216 FPS
• Medium: Average 171 FPS, Minimum 146 FPS, Maximum 197 FPS
• High: Average 136 FPS
• Ultra: Average 85 FPS

2560x1440:

• Low: Average 136 FPS

• Medium: Average 56 FPS, Minimum 48 FPS, Maximum 65 FPS
• High: Average 45 FPS
• Ultra: Average 28 FPS

At 1080p, the configuration is capable of high frame rates. The Low preset's 216 FPS average is more than sufficient for competitive play or high-refresh-rate monitors. The Medium preset's 171 FPS average with a tight min/max range of 146-197 FPS indicates stable performance with minimal frame time spikes. The High preset at 136 FPS is also smooth, while Ultra at 85 FPS remains playable but shows a significant performance cost relative to the visual improvements.

At 1440p, the Medium preset remains the most balanced, with a 108 FPS average and a 92 FPS minimum that avoids noticeable stutter. The High preset at 86 FPS is still acceptable, but the Ultra preset at 54 FPS dips below the 60 FPS threshold, which can be noticeable on standard monitors. At 4K, only the Low preset (71 FPS) provides a consistently playable experience. The Medium preset's 56 FPS average is borderline, and the High and Ultra presets at 45 FPS and 28 FPS, respectively, are not recommended for smooth gameplay. The data clearly shows that this combo is best suited for 1080p gaming, with 1440p possible at Medium settings, and 4K only viable at Low settings.
