The integrated Radeon 610M graphics are not used in this configuration, but their presence adds flexibility. Overall, the Ryzen 9 8945HX provides the computational foundation for the high frame rates observed across all settings and resolutions.

Resolution Scaling

The measured FPS data reveals how performance scales from 1080p to 4K across settings. At Low settings, the average FPS drops from 640 at 1080p to 404 at 1440p, then to 211 at 4K. This represents a 67.0% reduction from 1080p to 4K. At High settings, the average drops from 402 at 1080p to 254 at 1440p, then to 133 at 4K, a 66.9% reduction. At Medium settings, the average drops from 507 at 1080p to 320 at 1440p, then to 167 at 4K, a 67.1% reduction. At Ultra settings, the average drops from 251 at 1080p to 159 at 1440p, then to 83 at 4K, a 66.9% reduction.

The consistency of these reductions—approximately 67% from 1080p to 4K across all settings—indicates that the scaling is primarily resolution-driven rather than settings-driven. The pixel count increase from 1080p (2.07 million pixels) to 4K (8.29 million pixels) is exactly 4x, which would predict a 75% reduction in FPS if the GPU were purely pixel-bound. The observed 67% reduction suggests that the CPU is still contributing to frame generation, particularly at lower resolutions where the GPU has more headroom.

The data also shows the limiting component shifts with resolution. At 1080p Low, the 640 FPS average indicates the CPU is likely the limiting factor, as the RTX 4090 would be capable of higher frame rates in a less CPU-bound scenario. As resolution increases to 4K Ultra, the GPU becomes the limiting component, with the 83 FPS average reflecting the GPU's rendering load. The Medium preset at 4K shows a minimum FPS of 142, which is higher than the Ultra preset's average of 83, further confirming that settings have a larger impact than resolution alone at 4K. The scaling pattern suggests that for this combo, Minecraft is balanced such that neither component is severely underutilized at any tested configuration. The 67% FPS reduction from 1080p to 4K is close to the theoretical pixel-count scaling, indicating the GPU is doing most of the heavy lifting at higher resolutions, while the CPU's strong single-threaded performance maintains high frame rates at lower resolutions.
