Intel Lunar Lake Series To Feature Feature 64 Xe “Battlemage” EUs For iGPU

The launch of Intel’s upcoming mobile series, codenamed “Lunar Lake,” is approaching, and its exact specifications are becoming more apparent, thanks to reliable hardware leakers. Although Intel has confirmed that Lunar Lake will be aimed at low-power mobile platforms, specific details about its features remain undisclosed.

Lunar Lake is set to succeed the Core Ultra “Meteor Lake” series, utilizing the Alchemist GPU architecture, also known as Xe-LPG. This architecture is the same as the one powering Intel’s initial discrete Arc gaming graphics cards. However, Lunar Lake will boast a more advanced GPU design based on the Xe2-LPG architecture derived from Battlemage, the next-generation graphics. According to Bionic-Squash, Lunar Lake (LNL) will feature 64 Xe2 Execution Units (EUs), equivalent to 8 Xe-Cores, resulting in 1024 FP32 units dedicated to graphics calculations.

Regarding the number of EUs, the GPU configuration of Lunar Lake is comparatively lower than the full Raptor Lake mobile chip, which can have up to 96 EUs. However, this difference is due to Lunar Lake’s focus on optimized low-power consumption and efficiency, while Raptor Lake is designed for high-performance purposes. It is probable that Lunar Lake will complement the series, which will also include the Arrow Lake series, catering to both desktop and mobile segments.

A crucial distinction lies in the EU structure between Battlemage and Alchemist. Battlemage adopts the SIMD16 EU configuration, akin to Intel’s high-end data center GPU, Ponte Vecchio. Consequently, each EU in Battlemage can handle 16 operations per clock cycle, twice the capacity of Alchemist’s 8 operations. Consequently, the count of Xe cores is halved due to this difference.

Intel’s Lunar Lake architecture won’t be arriving anytime soon. It is set to incorporate Intel’s new 18A node and is now anticipated to be ‘manufacturing-ready’ in the second half of 2024, as confirmed by Intel CEO Pat Gelsinger during the recent Q2 23 earnings call.
