The video discusses Intel's latest Alder Lake processors, which introduce a big little architecture with P-cores and E-cores to improve performance and power efficiency. The P-cores handle demanding tasks, while the E-cores manage background tasks effectively. E-cores are smaller and focus on power efficiency, while P-cores are more powerful for heavy workloads. The 12th generation CPUs show significant performance improvements over previous generations, with a 40% increase over Skylake CPUs. This dual-core approach is innovative in increasing core counts and performance in PCs.

In this segment of the video, the focus is on Intel’s latest Alder Lake processors that feature two types of CPU cores – E-cores and P-cores. The video explains the evolution of CPU cores from single-core to multi-threading and multi-core configurations. Intel’s 12th generation CPUs introduce the concept of a big little architecture, where P-cores handle demanding tasks and E-cores manage background tasks efficiently to improve performance and power efficiency. P-cores are described as the most powerful cores in Intel’s layout, consuming more energy and running at higher clock speeds for heavy lifting tasks like gaming and processing loads. The Alder Lake series has received acclaim for this innovative dual-core approach.

In this part of the video, it is explained that Intel’s E-cores are smaller and weaker than P-cores but consume less power, focusing on power efficiency and performance per watt. E-cores complement P-cores by handling multi-core workloads and background tasks, leaving P-cores free for heavy workloads. The E-cores in Intel’s 12th generation CPUs are based on the Gracemont microarchitecture, succeeding the Tremont architecture. These low-power E-cores, with clock speeds as low as 700 MHz, perform well and outperform earlier generation cores. Intel claims that P-cores and E-cores in their 12th gen chips outperform their 11th gen chips by 19% and exceed Skylake CPUs by 40% in performance while using the same power. The concept of P-cores and E-cores is relatively new in x86 architecture, showing promising results in increasing core counts and performance in PCs.
