Intel Processors are Great But What is P and E Cores?

Since the introduction of their initial Turbo Boost technology, Intel has been pushing towards an hybrid model of performance to increase performance while reducing TDP. With the release of 12th Gen processors, Intel has taken that model a step forward by introducing two distinct types of cores: E (Performance) cores, and E (Efficiency Cores) which run at different speeds and power draws. What is the way Intel P and E cores differ and what impact do they have on single and multithreaded performance for typical applications?

Architecture Innovations using Intel P vs. E Cores

One of the biggest complaints about Intel's CPUs we've previously highlighted has been the absence of innovation in architecture in recent releases. Recently, instead of revising their processors to keep pace to AMD, Intel has simply increased the power of each core, increasing the performance and the temperatures as a result. However, this year, with 12th Gen CPUs like Intel Core I5-12400F Processor, Intel has achieved their most significant architectural shift in the last decade. to the first time, Intel has put two different kinds of cores on the same chip. This hybrid design lets the processor more effectively and efficiently handle various types of workloads, that is, multithreaded or light-weight as well as the reason for why core counts are higher in 12th Gen than they were with 11th. For instance, the flagship 11th Gen 11900k has eight total cores, whereas the 12900k like intel core i9 12900k processor includes 16 cores (8 P-cores and 8 E-cores).

What are P-Cores?

The Performance-cores (aka P-cores) require speed. They're built to run in the background and optimized for speed in single or lightly threaded applications such as gaming, and the majority of CAD software. They're similar to Intel's unlocked cores that run on its eleventh Gen processors, and the aim was to increase the speed as much as possible without worrying about metrics such as power efficiency. P-cores in Intel Core I5-12400F Processor can be multi-threaded, just like the older generations, which means that one core is equivalent to two threads.

What are E-Cores?

Efficiency-cores (aka E-cores) operate in the background to offer high computational capacity and are designed to scale high-speed threaded tasks and minimising interruptions due to tasks in the background. They can handle smaller workloads so that P-cores do not have to. E-cores operate at a lower rate than their P-core counterparts with the aim of maximizing efficiency and efficiency per Watt. E-cores in the intel core i9 12900k processor are also single threaded. which means one core equals one thread.

Is Intel 12th Gen Right for You?

The hardware choice depends on the workload, however due to this hybrid model, the 12th Gen Alder Lake may be the most flexible device Intel has ever produced. So, yes if you are looking for a high end PC that works smoothly with extra core and threads then Intel 12th gen would be perfect for you. We hope this information helps you in choosing the best processor for you.
