Intel’s Lunar Lake processors are set to make their debut in the second half of 2024, and some exciting details about these chips have recently been leaked. These processors are specifically designed for low-power notebooks and convertibles, distinguishing them from the high-performance PC-focused Arrow Lake family. One of the most significant differences between the two is the power envelope.

What sets Lunar Lake apart is its utilization of TSMC’s 3nm-class N3B node for fabrication, making it the first Intel CPU to leverage an external Foundry for the entire System on a Chip (SoC). This move showcases Intel’s commitment to pushing the boundaries of technology and partnering with industry leaders to deliver products.

Lunar Lake will feature up to 8 CPU cores, divided into 4 P and 4 E-Cores. The graphics architecture will be powered by Xe2, boasting 16-wide Simultaneous Multithreading (SMT) and up to 64 Vector Engines, providing a total of 1,024 shaders. The integrated GPU (iGPU) will also support real-time Ray Tracing and driver optimizations, promising an enhanced gaming and visual experience.

One notable addition to Lunar Lake is the introduction of a new System Cache, which will act as the last level of Static Random-Access Memory (SRAM) before accessing the main memory or Dynamic Random-Access Memory (DRAM). While it remains unclear whether this cache includes the Level 3 (L3) cache or serves as an additional layer, its presence signifies Intel’s focus on optimizing memory performance.

To accelerate AI workloads, Lunar Lake will incorporate a Neural Processing Unit (NPU) v4. This dedicated hardware component will enhance the efficiency and speed of artificial intelligence computations, catering to the growing demand for AI capabilities in various applications.

Memory-wise, Lunar Lake will employ on-die LPDDR5X memory clocked at an impressive 8,533 megatransfers per second (MT/s). The planned variants will offer 16GB and 32GB options, supporting dual-channel memory for improved data throughput. In terms of connectivity, users can expect 4x PCIe Gen 5 and 4x Gen 4 lanes, along with 3x Thunderbolt 4 and 2x USB 3 ports.

Intel has also prioritized power efficiency in Lunar Lake, incorporating an advanced Power Unit on the SoC. This feature aims to optimize battery life and minimize standby power consumption, crucial factors for sub-15W notebooks and Tablets powered by these chips.

The Lunar Lake MX mobile lineup will consist of four SKUs, including two Core 7 and two Core 5 chips. While all four SKUs share the same CPU core count of 8, the memory and system cache configurations will differentiate them. Additionally, the Core 7 CPUs will boast one unit higher in iGPU cores and NPU tiles, offering enhanced performance for those seeking top-tier specifications.

Intel’s Lunar Lake processors will leverage the 2nd Gen Foveros 3D packaging technology. This advanced packaging technique allows for stacking LPDDR5x memory packages onto the base die, with the CPU/iGPU tile placed on the Foveros die. This innovative approach enables efficient use of space and improved thermal management, contributing to overall performance gains.

With Lunar Lake’s anticipated release in the second half of 2024, Intel is poised to deliver a lineup of processors that cater to the needs of low-power notebooks and convertibles. By partnering with TSMC for fabrication and incorporating advanced technologies such as real-time ray tracing and AI acceleration, Intel aims to solidify its position as a leading player in the mobile computing market. As consumers eagerly await the arrival of these processors, it is clear that Lunar Lake represents another significant leap forward in Intel’s ongoing pursuit of technological excellence.
