Minecraft

Minecraft’s performance with the AMD Ryzen AI Max+ 395 and NVIDIA GeForce RTX 4090 Mobile is defined by an extreme CPU bottleneck at lower resolutions, with the GPU only becoming a meaningful constraint at 4K Ultra settings. The measured frame rates show a system that can push well beyond display refresh rates in most scenarios, but the scaling patterns reveal that the processor is the primary limiter for the majority of the tested configurations.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen AI Max+ 395 is a 16-core, 32-thread processor based on the Zen 5 architecture, with a base clock of 3.00 GHz and a boost clock of 5.10 GHz. It features a shared 64 MB L3 cache and per-core L1 and L2 caches of 80 KB and 1 MB respectively. The CPU’s benchmark scores are strong, with a Cinebench R23 multi-core score of 35314 and a single-core score of 2044, while Geekbench results show 20992 multi-core and 2464 single-core. Its PassMark multithread score is 54934, and it sits in the 95th percentile among all CPUs.

In Minecraft, the data indicates that this processor is the dominant factor in frame rate output at 1080p and 1440p. The jump from Low to Ultra settings at 1920x1080 shows a drop from 640 FPS to 251 FPS, which is a 61% reduction in performance. This scaling is not typical of a GPU-bound workload; rather, it suggests that the CPU is able to feed frames at an extremely high rate, and the increasing settings impose additional draw calls and world-generation tasks that the processor must handle. The CPU’s 16 cores are not fully utilized by Minecraft’s engine, which traditionally relies more on single-thread performance, but the high boost clock of 5.10 GHz and the substantial L3 cache help maintain very high frame rates.

The CPU’s nearest rivals include the AMD Ryzen Threadripper PRO 9945WX, which has an average benchmark score 1.6% higher, and the Intel Core i9-14900K, which is 1.7% higher. The AMD Ryzen 9 8945HX trails by 2%. These deltas are small, indicating that the Ryzen AI Max+ 395 is competitive with top desktop processors in raw compute, but Minecraft’s specific workload may benefit from the higher single-thread performance of rivals like the i9-14900K. The data shows that the CPU’s performance is sufficient to drive 4K High settings at 133 FPS, which is well above playable thresholds, but the bottleneck shifts at 4K Ultra where the frame rate drops to 83 FPS.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear pattern of resolution scaling that shifts the bottleneck from CPU to GPU. At 1920x1080 Low, the system achieves 640 FPS, which drops to 404 FPS at 2560x1440 Low, and further to 211 FPS at 3840x2160 Low. This represents a 67% reduction from 1080p to 4K, but the absolute values remain extremely high, indicating that the CPU is still capable of feeding the GPU at 4K Low with a 211 FPS average.

The High settings show a similar trend: 402 FPS at 1080p, 254 FPS at 1440p, and 133 FPS at 4K. The drop from 1080p to 1440p is 36.8%, while the drop from 1440p to 4K is 47.6%. This accelerating decline as resolution increases suggests that the GPU’s pixel throughput is becoming a more significant factor, but the CPU’s role is still dominant at 1440p. The Ultra settings provide the clearest evidence of the GPU bottleneck: 251 FPS at 1080p, 159 FPS at 1440p, and 83 FPS at 4K. The drop from 1440p to 4K is 47.8%, which is nearly identical to the High setting drop, but the absolute FPS at 4K Ultra is below 100, indicating that the RTX 4090 Mobile is the limiting component in this specific configuration.

The Medium settings, which have recorded min and max FPS values, show a more nuanced picture. At 1080p, the average is 507 FPS with a min of 431 and max of 583, while at 1440p, the average is 320 FPS with a min of 272 and max of 368. At 4K, the average is 167 FPS with a min of 142 and max of 192. The range between min and max FPS narrows as resolution increases, from a 152 FPS spread at 1080p to a 50 FPS spread at 4K, which indicates that the CPU’s frame pacing variability is smoothed out when the GPU becomes more constrained. This data supports the conclusion that the CPU is the primary limiter at 1080p and 1440p, while the GPU takes over at 4K, especially at Ultra settings.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the Medium preset offers the best balance of performance and visual quality across all three resolutions. At 1920x1080, Medium settings deliver an average of 507 FPS with a minimum of 431 FPS, which is well above any display refresh rate and provides a smooth experience without the frame rate fluctuations seen in the Low preset’s 640 FPS average. The Medium preset at 2560x1440 achieves 320 FPS average with a 272 FPS minimum, which is still exceptionally high for a 1440p resolution and offers a significant visual upgrade over Low settings.

At 3840x2160, Medium settings produce an average of 167 FPS with a minimum of 142 FPS, which is the only 4K preset with recorded min FPS data. This makes it the most reliable choice for 4K gaming, as the 142 FPS minimum ensures consistent frame delivery without drops below 100 FPS. The High preset at 4K achieves 133 FPS average, but without a recorded minimum, the frame pacing is less certain. The Ultra preset at 4K drops to 83 FPS average, which may be acceptable for slower-paced gameplay but is below the threshold for high-refresh-rate monitors.

For users with 1080p or 1440p displays, the High preset at 402 FPS and 254 FPS respectively offers a better visual experience than Medium, with only a modest FPS reduction. However, the Medium preset’s recorded minimum FPS values provide a more stable experience, particularly if frame time consistency is prioritized over raw average FPS. The Ultra preset is only recommended for 1080p displays, where the 251 FPS average still provides a smooth experience, but at 1440p and 4K, the 159 FPS and 83 FPS averages respectively are less compelling compared to the High preset’s superior performance.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4090 Mobile is based on the AD103 chip with Ada Lovelace architecture, featuring 9728 shading units, 304 texture mapping units, and 112 raster output units. It has 76 ray tracing cores and 304 tensor cores, with a base clock of 1335 MHz and a boost clock of 1695 MHz. The GPU’s memory configuration includes 16 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 576.0 GB/s. The memory clock is 2250 MHz, with an effective data rate of 18 Gbps. The GPU’s FP32 performance is 32.98 TFLOPS, and it supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

In Minecraft, the GPU’s role is secondary to the CPU at lower resolutions, but it becomes critical at 4K Ultra settings. The RTX 4090 Mobile’s 16 GB VRAM is sufficient for Minecraft’s texture requirements, even at 4K with High settings, which achieve 133 FPS. The GPU’s 256-bit memory bus and 576.0 GB/s bandwidth are not fully utilized until 4K resolutions, where the pixel fill rate and texture bandwidth become more demanding. The GPU’s pixel rate of 189.8 GPixel/s and texture rate of 515.3 GTexel/s contribute to its ability to maintain 133 FPS at 4K High, but the 83 FPS at 4K Ultra suggests that the GPU’s shading units and memory bandwidth are the limiting factors at the highest settings.

The GPU’s benchmark scores show a PassMark G3D score of 27212 and a Geekbench OpenCL score of 180831, placing it in the 84th percentile among all GPUs. Its nearest rivals include the NVIDIA RTX A6000, which scores 0.9% higher, and the NVIDIA GeForce RTX 5050 Mobile, which scores 0.9% lower. The RTX 4090 Mobile’s performance is competitive with these parts, but Minecraft’s workload does not heavily utilize the GPU’s ray tracing or tensor cores, as evidenced by the frame rate scaling that is more dependent on CPU performance. The data shows that the GPU only becomes the bottleneck at 4K Ultra, where the 83 FPS average is a clear indication that the RTX 4090 Mobile is being pushed to its limits.
