How do Intel P vs E cores compare and how do they impact both single and multithreaded performance in common applications?<\/p>\n<h2><strong>Architecture Innovations with Intel P vs E Cores<\/strong><\/h2>\n<p>One of the bigger criticisms of Intel\u2019s CPUs that we\u2019ve highlighted in the past is the lack of architectural innovation in their recent launches. Lately, instead of re-engineering their chips to keep pace with AMD, Intel has simply fed more juice to each core, increasing both performance and heat as a result. But with 12<sup>th<\/sup> Gen, Intel has made their biggest architectural shift in a decade \u2014 for the first time ever, Intel has put two different types of cores on the same die. This hybrid model allows the processor to better and more efficiently handle different types of workloads, both lightly and multithreaded, and the reason why core counts are so much higher with 12<sup>th<\/sup> Gen than they were in 11<sup>th<\/sup>. For example, the flagship 11<sup>th<\/sup> Gen 11900k has 8 total cores whereas the 12900k has 16 cores (8 P-cores+8 E-cores).<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full\" src=\"https:\/\/velocitymicro.com\/images\/upload\/Intel-P-vs-E-Core.png\" alt=\"Intel P vs E Core\" width=\"3840\" height=\"2160\" \/><\/p>\n<h2><strong>What are P-Cores <\/strong><\/h2>\n<p>Performance-cores (aka P-cores) have a need for speed. They\u2019re designed to run in the foreground and optimized for performance in single and lightly threaded applications like gaming and most CAD programs. These are similar in design to Intel\u2019s unlocked cores on their 11<sup>th<\/sup> Gen processors, where the goal was to max out frequency whenever possible without concern for metrics like power efficiency. P-cores are multi-threaded like previous gen, so one core = two threads.<\/p>\n<h2><strong>What are E-Cores<\/strong><\/h2>\n<p>Efficient-cores (aka E-cores) run in the background to provide computational density and are optimized for scaling highly threaded workloads and minimizing the interruptions from background task management. They take on the lighter loads so the P-cores don\u2019t have to. E-cores run at a lower frequency than their P-core counterparts, with the goal being maximizing efficiency and performance per watt. They\u2019re also single threaded, so one core = one thread.<\/p>\n<h2><strong>Intel Thread Director<\/strong><\/h2>\n<p>This hybrid type model only works if your PC can discern which cores\/threads are best used for specific tasks and successfully manages that workload properly. Enter Intel Thread Director. Integrated into the die itself, Intel Thread Director is a hardware\/software solution that communicates with the operating system to make the scheduling decisions that determine which workloads can and should be offloaded to which type of core and dynamically adapts those guidances without any user input for the sake of maximizing efficiency and performance. In simpler terms, it decides which workloads can run just as well on the slower threads, leaving the faster threads open for when they\u2019re needed. That makes it a critical piece of the puzzle and why 12<sup>th<\/sup> Gen has been so well received thus far.<\/p>\n<p>Note: Thread Director is designed for <a href=\"https:\/\/www.velocitymicro.com\/blog\/whats-new-windows-11\/\">Windows 11<\/a> which is why we recommend it with 12<sup>th<\/sup> Gen, though Windows 10 users will still see some of its benefits. Linux support is \u201cin development\u201d but not here yet.<\/p>\n<h2><strong>Is Intel 12<sup>th<\/sup> Gen Right for You?<\/strong><\/h2>\n<p>Hardware choice is always reliant on workload, but because of this new hybrid model, 12<sup>th<\/sup> Gen Alder Lake may be the most versatile chip Intel has ever made. Whether you\u2019re primarily a gamer or CAD designer mainly using just a few cores or a content creator regularly using multiple cores, the <a href=\"https:\/\/www.velocitymicro.com\/blog\/intel-12th-gen-core-benchmarks\/\">lift in benchmark numbers<\/a> is pretty astounding. Couple that performance boost with DDR5 support, and this is an easy one to recommend to many customer types.
