Unique cache setup with shared L3 cache and exclusive L2 cache
Expected to offer 2-3 times faster performance with integrated NPU

Intel’s highly anticipated Lunar Lake CPUs have made an unexpected appearance, causing a stir among tech enthusiasts. A leaked early sample of the processor, known as the A1 stepping, reveals some intriguing details about its specifications and capabilities.

One of the most notable aspects of the Lunar Lake CPU is its configuration. It boasts 8 cores and 8 threads, indicating the absence of hyper-threading, similar to Intel’s Arrow Lake. The processor is equipped with 12MB of L3 cache, 14MB of L2 cache, and 832KB of L1 cache. Interestingly, the L3 cache is shared between the P and E cores, while the L2 cache is exclusive to individual P-Cores or a quad-cluster of E-Cores. This unique setup creates a 4P+4E configuration, consisting of 4 Lion Cove and 4 Skymont cores.

Delving deeper into the specifications, it is expected that each P-core will feature 2.5MB of L2 cache per core, leaving the remaining 4MB for the E-core cluster. The CPU operates at a base clock speed of 1.80GHz, with an impressive operating frequency of 2.78GHz for an engineering sample. To complement its processing power, the Lunar Lake CPU is paired with 32GB of LPDDR5/5x memory and features an integrated NPU (Neural Processing Unit), similar to Intel’s Meteor Lake.

While specific release dates are yet to be confirmed, Lunar Lake is expected to launch alongside Arrow Lake in the second half of 2024. Both processors will share the same core architectures, Lion Cove and Skymont. However, Lunar Lake will be manufactured using TSMC’s N3P process node, setting it apart from its counterpart. Additionally, the NPU unit in Lunar Lake is anticipated to deliver 2 to 3 times faster performance compared to the one found in Meteor Lake.

Graphics performance is also set to receive a significant boost with the Lunar Lake CPU. The integrated iGPU tile is projected to offer an impressive 20-40% uplift over the Xe-LPG unit that powers Core Ultra. This enhancement promises improved visual experiences and smoother graphics-intensive tasks.

One intriguing detail revealed by Xino, a tech insider, is that the Lion Cove core will feature an additional L0 cache layer derived from a renamed L1 cache. This L1 cache will function as a Latency-reduced L2 cache layer with a similar width to traditional L2 buffers. Ultimately, this addition aims to enhance data caching capabilities, resulting in improved overall performance.

As the Lunar Lake CPU leaks continue to generate excitement, Intel enthusiasts eagerly await further details and benchmarks to gauge its true potential. With its impressive core configuration, cache capacity, and enhanced NPU and iGPU performance, Lunar Lake has the potential to be a game-changer in the world of processors.

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.

iGPU: An integrated Graphics Processing Unit (iGPU) is a component built into a computer's central processing unit (CPU) or system-on-chip (SoC) that handles graphical tasks. Unlike dedicated graphics cards, which are separate components, an iGPU shares system resources with the CPU, allowing for basic graphics capabilities without the need for an additional card. While typically less powerful than dedicated GPUs, iGPUs are energy-efficient and well-suited for everyday computing tasks

L3 cache: L3 cache is a type of computer memory that is used to store frequently used data and instructions.
