I've observed your CPU's power consumption fluctuating noticeably depending on the task. Even when running full load across all threads, usage stays relatively stable around 85 watts. In contrast, specialized applications like image generation or rendering can spike to 110-150 watts while maintaining high utilization. The consistent boost frequency suggests your system is optimized for performance rather than efficiency. This behavior is common in multithreaded workloads where the CPU prioritizes speed over power savings. Your curiosity is appreciated!

I'm not an expert, but I think the issue stems from varying instruction pipeline lengths and the specific instructions used, like AVX. Longer pipelines run smoother but create more heat. I'm curious to hear if anyone has more insights or corrections.

It relates to cache size, CPU memory access needs, and instruction types. Your program is compact enough to fit in the CPU’s level 2 cache, with little RAM usage and only basic instructions. Blender leverages AVX and other sets, while π is highly optimized.

This essentially describes the situation. The total processing capacity is fixed, but the amount of power consumed depends on how it's utilized.

It's Java, a language that runs on the JVM and uses managed memory. This setup makes it challenging to fully utilize your CPU's capabilities.
