Intel’s 16th Gen Lunar Lake CPU Launched: Powerful 20A/2nm Chip with Enhanced Cores and L3 Cache


October 8, 2023 by our News Team

Intel has launched exciting details about their upcoming 16th Gen Lunar Lake processors, featuring 4 P cores and 4 E cores with increased cache sizes, built on Intel's advanced 20A process node for enhanced performance and power efficiency for mobility devices.

  • Octa-core processor with 4 P cores and 4 E cores
  • P cores feature 25% increase in L2 cache compared to 14th Gen P cores
  • Built on Intel's 20A process node, a 2nm-class node set to be introduced next year


Intel has recently launched some exciting details about their upcoming 16th Gen Lunar Lake processors. Although the official release is still a while away, a CPU from the Lunar Lake family has been spotted on the SiSoft Sandra database, giving us a glimpse into its impressive capabilities.

The Lunar Lake processor in question is an octa-core part, featuring 4 P cores and 4 E cores. The P cores come with a generous 2.5MB of L2 cache each, which is a 25% increase compared to the 14th Gen P cores. On the other hand, the E-core cluster shares a chunk of 4MB. All the P and E cores benefit from a shared L3 cache of 16MB. The P-Cores have a peak clock speed of 3.91GHz, while the E-Cores top out at 2.61GHz.

One of the most exciting aspects of the 16th Gen Lunar Lake CPUs is their fabrication process. These processors will be built on Intel’s 20A process node, which is a 2nm-class node set to be introduced next year. Initially, Lunar Lake was planned to be an 18A (1.8nm) product, but due to the ahead-of-schedule production of the 20A node, Intel made the decision to switch.

Intel’s roadmap reveals that the 16th Gen Lunar Lake chips are specifically designed for mobility devices with always-on capability. This means that power efficiency is a key focus for these processors. The node shrink to the 20A process indicates a tick rather than a tock, suggesting minimal changes to the core architecture compared to its predecessor, the 14th Gen Meteor Lake processors.

Interestingly, the core architectures used in Lunar Lake are the same as those found in Arrow Lake. The P-cores are based on Lion Cove architecture, while the E-cores utilize Skymont architecture. This particular Lunar Lake sample has an average TDP of 17W, indicating that it is intended for ultrabook SoCs meant for always-on devices. However, it’s important to note that we shouldn’t expect the 16th Gen processors to hit the market before late 2025.

Overall, Intel’s 16th Gen Lunar Lake CPUs promise to deliver impressive performance and power efficiency for mobility devices. With their enhanced cores, increased cache sizes, and the utilization of the advanced 20A process node, these processors are set to take computing to new heights. While we eagerly await their official release, it’s clear that Intel is pushing the boundaries of innovation in the world of CPUs.

Technology Explained


CPU: The Central Processing Unit (CPU) is the brain of a computer, responsible for executing instructions and performing calculations. It is the most important component of a computer system, as it is responsible for controlling all other components. CPUs are used in a wide range of applications, from desktop computers to mobile devices, gaming consoles, and even supercomputers. CPUs are used to process data, execute instructions, and control the flow of information within a computer system. They are also used to control the input and output of data, as well as to store and retrieve data from memory. CPUs are essential for the functioning of any computer system, and their applications in the computer industry are vast.


E-Cores: E-Cores (Efficiency Cores) are a type of technology used in the computer industry to provide a more efficient and reliable way of powering and cooling computer components. They are made up of a combination of copper and aluminum, and are designed to be more efficient than traditional copper cores. E-Cores are used in a variety of applications, such as in CPUs, GPUs, and other computer components. They are also used in servers, laptops, and other electronic devices. The technology is designed to reduce heat and power consumption, while also providing a more reliable and efficient way of powering and cooling computer components.


L3 cache: L3 cache is a type of computer memory that is used to store frequently used data and instructions. It is located between the processor and main memory, and is used to reduce the amount of time it takes for the processor to access data from main memory. This helps to improve the overall performance of the computer. In the computer industry, L3 cache is used in many applications, such as gaming, video editing, and web browsing. It can also be used to improve the performance of servers and other high-performance computing tasks. By providing faster access to data, L3 cache can help to reduce the amount of time it takes for a computer to complete a task.


P-Cores: P-Cores (Performance Cores) are a type of processor technology developed by Intel that is designed to improve the performance of computer systems. This technology is based on the concept of multi-core processors, which are processors that contain multiple cores or processing units. P-Cores are designed to increase the speed and efficiency of computer systems by allowing multiple cores to work together in parallel. This technology is used in a variety of applications, including gaming, video editing, and data analysis. P-Cores are also used in servers and other high-performance computing systems. The technology is also used in mobile devices, such as smartphones and tablets, to improve battery life and performance. P-Cores are an important part of the computer industry, as they allow for faster and more efficient computing.
