Intel Lunar Lake MX To Feature 4+4 CPU Cores And 8 Xe2 GPU Cores, To Be Built On TSMC N3B Node

YuuKi-AnS posted the slides on Twitter, but they were swiftly taken down. An Anandtech forum member named Geddagod has preserved all the details, encompassing information about the new CPU series tailored for low-power systems with a range of 8W to 30W. Contrary to being a high-end gaming architecture replacing Meteor Lake-H, it serves as a successor to the yet-to-be-officially-released Meteor Lake-U.


Intel asserts that the Lunar Lake architecture was collaboratively developed with Microsoft to achieve efficient software/hardware integration. It includes a next-gen integrated NPU 4.0 (Neural Processing Unit) supported by modern Xe2-LPG graphics. Notably, the Lunar Lake MX series introduces the “Battlemage” series as the first known power-efficient version. Today’s confirmation reveals that the Core 7 (200?) series will boast up to 8 Xe-Cores, representing an evolution of Arc graphics extending to both mobile and desktop discrete graphics.

Featuring 64 Vector Engines, support for Systolic AI/Super Scaling technologies, and real-time ray tracing, this GPU architecture is noteworthy. Additionally, details reveal that the Lunar Lake MX GPU will provide support for DisplayPort 1.4, HDMI 2.1, eDP1.4 & 1.5, along with hardware VVC/H.266 video decoding support.


Lunar Lake MX architecture is set to include on-package memory, with available options of 16 GB and 32 GB, as indicated in the slides. Intel intends to offer at least four variants with varying layouts of CPU and GPU cores. The CPU architecture combines Lion Cove and Skymont cores, and notably, the CPU tile will be produced using TSMC N3B process technology.

Supporting dual-channel LPDDR5X-8533 memory, the architecture incorporates on-package memory (MoP). Intel’s integration of memory serves to conserve power (through reduced routing and an integrated memory subsystem) and minimize size (approximately 100-250 mm2). The package, measuring 27.5 mm x 27 mm, comprises two tiles: one for CPU & GPU and a separate SoC tile.


The Lunar Lake MX series is set to support both PCIe Gen5x4 and Gen4x4 interfaces, along with Thunderbolt 4 and up to three USB4 connectors. Integrated WiFi-7 and Bluetooth 5.4 support is facilitated through the BE201 network card, utilizing the CNVio3 interface.

Notably, there’s mention of a special 8W SKU of Lunar Lake capable of operating without a fan, while the fanned version falls within the 17 to 30W TDP range. Additionally, it’s stated that the 12W version of the Arc Xe2-LPG GPU could deliver 2.5 TFLOPS of single-precision compute performance, equivalent to the Apple M1 chip. Despite reaching a peak Arc performance of 3.8 TFLOPS, this figure remains below the design of the Apple M2 SoC.


Considering the purported power efficiency and GPU performance, there’s anticipation for the integration of the Lunar Lake MX series into upcoming handheld systems. Although the exact speed improvement of the Battlemage GPU architecture over Alchemist is yet unknown, the imminent launch of Meteor Lake chips featuring the Xe-LPG (Alchemist) series next month will provide a valuable baseline.

The official debut of the Intel Lunar Lake MX series is slated for 2024.
