Minecraft

The AMD Ryzen 5 4600G paired with the Intel Arc B390 produces a highly resolution-sensitive experience in Minecraft, with frame rates swinging dramatically based on both resolution and quality preset. At 1080p, the combination delivers playable to excellent performance, but 4K Ultra proves too demanding for this hardware pairing.

Resolution Scaling

The measured frame rates show a clear pattern of performance degradation as resolution increases, but the severity of that drop depends heavily on the settings preset. At Low settings, the average frame rate falls from 216 FPS at 1920x1080 to 136 FPS at 2560x1440, a 37% reduction, and then further to 71 FPS at 3840x2160, representing a 67% total drop from 1080p to 4K. This steep decline indicates that even at Low settings, the rendering load at 4K overwhelms the Arc B390's capabilities.

The Medium preset tells a similar story with slightly compressed margins. Starting at 171 FPS at 1080p, the average drops to 108 FPS at 1440p, a 37% decrease, and then to 56 FPS at 4K, a 67% reduction from the baseline. The pattern is consistent: a roughly two-thirds performance loss when moving from 1080p to 4K, regardless of whether the game runs at Low or Medium settings.

High settings exhibit the same scaling trend but with lower absolute numbers. The 1080p average of 136 FPS falls to 86 FPS at 1440p, a 37% drop, and then to 45 FPS at 4K, a 67% reduction. The consistency of these percentage drops across Low, Medium, and High suggests that the limiting factor is primarily the GPU's pixel throughput rather than CPU-bound bottlenecks, as the scaling remains proportional even when the workload changes.

Ultra settings present the most extreme case. The 1080p average of 85 FPS drops to 54 FPS at 1440p, a 36% decrease, and then to 28 FPS at 4K, a 67% reduction. The 4K Ultra result of 28 FPS is the lowest measured value in the entire dataset, and it falls below the 30 FPS threshold that most players consider the minimum for acceptable gameplay. The scaling curve for Ultra follows the same proportional pattern as the other presets, confirming that resolution scaling is consistent across quality levels.

The data indicates that the Arc B390 is the dominant bottleneck at higher resolutions. The Ryzen 5 4600G, with its 6 cores and 12 threads, provides sufficient CPU headroom to feed the GPU at 1080p, but as pixel count increases, the GPU's shading units and ROPs become the constraint. The 24 ROPs and 48 TMUs in the Arc B390 are simply insufficient for 4K rendering in Minecraft, particularly at higher quality settings.

GPU Role

The Intel Arc B390 is an integrated graphics solution based on the Xe3-LPG architecture, manufactured on Intel's 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz, with system-shared memory providing both capacity and bandwidth. The memory bandwidth is listed as system dependent, which means performance can vary based on the host system's DDR4 configuration.

The GPU's compute resources are modest: 1536 shading units, 48 texture mapping units, and 24 raster output units. The pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s provide theoretical maxima, but the measured frame rates show that real-world performance falls well short of these limits at high resolutions. The FP32 throughput of 7.680 TFLOPS sounds respectable on paper, yet the 4K Ultra result of 28 FPS demonstrates that raw compute does not translate directly to playable frame rates in Minecraft's block-based rendering.

The Arc B390's benchmark standing is telling. Its average 3DMark Steel Nomad DX12 score of 1482 places it in the 9th percentile of all GPUs, and its nearest rivals are all legacy NVIDIA parts: the GeForce GT 520MX with a 1.3% higher score, the GeForce 800M with a 1.5% higher score, and the GeForce GT 625 OEM with a 2.5% higher score. This positions the B390 as a very low-end graphics solution, comparable to integrated graphics from a decade ago in terms of raw performance.

The system-shared memory architecture means the GPU has no dedicated VRAM. This is particularly relevant for Minecraft, where texture loading and chunk rendering can benefit from dedicated graphics memory. The absence of dedicated VRAM forces the GPU to contend with the CPU for system memory bandwidth, which likely contributes to the steep performance drop at 4K where memory pressure increases significantly.

The 12 ray tracing cores are present but do not appear to provide meaningful benefit in this context, as Minecraft's default rendering path does not heavily utilize ray tracing. The DirectX 12 Ultimate support with version 12_2 features is technically capable, but the hardware's low throughput limits its practical impact. The Vulkan 1.4 and OpenGL 4.6 API support provide compatibility, but again, the fundamental hardware limitations dominate the measured results.

Settings Recommendations

The measured data clearly identifies the optimal settings for each resolution. At 1920x1080, the High preset delivers 136 FPS average, which is more than sufficient for smooth gameplay, while the Medium preset offers 171 FPS for those prioritizing frame rate. The Ultra preset at 85 FPS is playable but represents a significant performance cost for marginal visual gains over High.

At 2560x1440, the Medium preset emerges as the best balance, with a 108 FPS average and a minimum of 92 FPS ensuring no noticeable stuttering. The High preset at 86 FPS is acceptable for most players, but the Ultra preset's 54 FPS average falls into a range where some players may notice reduced smoothness. The Low preset at 136 FPS is available for competitive play but sacrifices visual quality unnecessarily given Medium's strong performance.

At 3840x2160, the situation becomes more constrained. The Low preset at 71 FPS is the only option that provides comfortable frame rates, while the Medium preset at 56 FPS may be tolerable for players willing to accept occasional dips to 48 FPS. The High preset at 45 FPS is borderline, and the Ultra preset at 28 FPS should be avoided due to sub-30 FPS averages.

For the best overall experience, the 1920x1080 High preset delivers a strong combination of visual quality and performance, with 136 FPS average providing headroom for demanding scenes. Players with 1440p monitors should choose the Medium preset, while 4K users should stick to Low settings for acceptable playability. The data does not support using Ultra settings at any resolution, as the performance penalty is disproportionate to the visual benefit.
