Intel’s Lunar Lake chips may be the first to include an Arc Battlemage GPU

Lunar Lake is envisioned as a mobile-oriented architecture, emphasizing low power consumption and performance per watt. It is anticipated to follow Meteor Lake, possibly co-existing with it if Intel decides to split its mobile chips into two performance tiers.

Back in January, Intel revealed that the Lunar Lake (LNL) architecture is being designed for ultrathin laptops with the aim of preserving performance while ensuring all-day battery life. As such, the LNL CPUs are said to target a 15 W or below TDP. Furthermore, it is expected that the Lunar Lake chips will employ an Xe2-LPG iGPU based on the next-gen Battlemage architecture. Adding to the growing pile of Lunar Lake leaks, Moore’s Law Is Dead and Bioinic_Squash have ousted more details regarding the architecture.

According to these sources, Lunar Lake CPUs are anticipated to reach a maximum of 8 cores, comprising 4 Lion Cove+ P-cores and 4 Skymont E-cores. The leaker describes the LNL Lion Cove+ P-cores as an “early implementation,” and there are suggestions that the LNL processors might not feature the “working Rentable Units” that are expected to appear in Arrow Lake chips..

On the desktop side, we can expect Raptor Lake refresh CPUs later in 2023, followed by Arrow Lake chips in 2024. This separation between mobile and desktop architectures offers clarity and makes it easier to navigate the various developments.

According to the reported leaks (via Notebookcheck), Lunar Lake is set to feature up to four Lion Cove P-cores and 4 Skymont E-cores. Though the multithreading performance might seem modest, it’s essential to remember that these are likely 15W U class CPUs. For comparison, Intel’s top-end Raptor Lake U processor, the i7 1365U, has two performance cores and eight E-cores. In many workloads, the higher P-core count should yield tangible benefits.

Regarding hyperthreading for the P-cores, MLID mentioned the possibility of it being absent. However, there are reservations about this claim, as traditionally, a 4C/4T implementation is preferred over 2C/4T, with 4C/8T being even better.

A notable aspect of Lunar Lake chips is the potential inclusion of an Arc Battlemage GPU tile, boasting up to 64 Xe2 execution units. While information about Battlemage remains scarce, it is safe to assume that it will outperform Arc Alchemist. Given Intel’s advancements in driver development and identification of architectural bottlenecks, it is reasonable to speculate that Intel’s mobile graphics will take a significant leap forward.
