SCENARIO
When we think of our PC CPUs, we often imagine them as simple calculation units, capable of executing tasks of varying complexity depending on the usage scenarios. However, CPUs are highly sophisticated devices, designed to execute instructions sequentially at a specific operating frequency.
Over the decades, the operating frequency of CPUs has undergone extraordinary evolution. We have moved from the first CPUs operating at a few dozen Hertz (Hz) to today's processors reaching speeds of 5-6 gigahertz (GHz). This incredible progress has enabled the execution of increasingly complex tasks and paved the way for technological innovations that were once unimaginable.
The introduction of multi-core CPUs has significantly evolved the concept of multitasking, better supporting the simultaneous execution of multiple processes. Multi-core CPUs introduced the paradigm of multi-threaded applications, allowing software to distribute workloads across multiple cores to improve efficiency and performance.
But innovation didn't stop there. In the last decade, we have seen the introduction of hybrid CPUs in the market. These processors not only maintain the classic x86 component for standard operations but also integrate a graphics component.
Accelerated Processing Units (APUs) can exploit, through specific software, the parallel computing capabilities of integrated graphics cards (iGPU), improving energy efficiency and overall system performance.
These evolutions have been accompanied by increasingly specific and sectorial needs. For daily tasks, a simple CPU is more than sufficient. However, there are professional sectors that require significant computing power. Consequently, today we have processors designed for different usage ranges: from mainstream to enthusiast, up to processors dedicated to data centers.
