Intel 12th Gen only efficient core were used for the computation

I'm sorry, but I'm not sure what specific computation or scenario you are referring to with "Intel 12th Gen only efficient core were used for the computation."

However, I can provide some general information about Intel's 12th Generation processors. The Intel 12th Gen processors, also known as Alder Lake, introduce a hybrid architecture that combines high-performance cores with high-efficiency cores. This hybrid architecture allows the processor to dynamically allocate workloads to the most suitable cores based on the performance requirements of the task.

The high-performance cores are designed to handle demanding workloads that require significant processing power, such as gaming or content creation. They typically offer higher clock speeds and larger cache sizes, enabling them to deliver faster single-threaded performance.

The high-efficiency cores, on the other hand, are optimized for power efficiency and handling lighter workloads. They are designed to provide improved power efficiency, longer battery life, and handle tasks that don't require the full power of the high-performance cores. These cores are generally used for background tasks, light browsing, or other low-demand activities.

The dynamic allocation of workloads between the high-performance and high-efficiency cores is handled by the operating system and hardware-level mechanisms. The goal is to maximize performance while minimizing power consumption, resulting in more efficient overall operation.

It's important to note that the specific utilization of the cores during a computation or workload depends on various factors, including the operating system, software, workload characteristics, and how the workload is parallelized. The task scheduler of the operating system plays a crucial role in managing the allocation of work to different cores.

If you have a specific scenario or use case in mind, providing more details would allow for a more specific and accurate response.
