New AI PC Platform with Integrated Memory Boosts Efficiency and Performance, Redefining Future Laptops
Summary:
Intel’s Lunar Lake AI PC platform integrates memory on chip, enhancing efficiency and performance, eliminating the need for separate RAM modules.
(AIM)—Intel has announced a significant architectural shift to support AI advancements with the introduction of the Lunar Lake low-power mobile platform. This new system-on-chip (SoC) architecture, unveiled recently, marks a departure from traditional designs by integrating 16GB or 32GB of LPDDR5X memory directly on the chip. This Memory on Package (MoP) approach is set to reduce data transmission power consumption by approximately 40%, significantly improving laptop battery life.
The new Lunar Lake platform succeeds the Meteor Lake Core Ultra processors launched last year, saving 250mm² of space. For users with high memory demands, Intel plans to release a separate architecture named Arrow Lake later this year.
Key enhancements with the SoC design include a threefold increase in AI accelerator scale, over fourfold improvement in performance, 14% better CPU performance at the same clock speed, 50% enhanced graphics performance, and a 60% boost in battery life. Rob Hallock, Intel’s Senior Director of Technical Marketing, stated, “This is x86 performance like you’ve never seen before.”
Lunar Lake’s architecture features two distinct Tiles: Compute Tile and Platform Controller Tile, connected via Foveros packaging technology. The Compute Tile replaces Meteor Lake’s LP-E cores with a new 4×4 system, incorporating up to four new Lion Cove P cores and four new Skymont E cores, delivering impressive x86 efficiency. The E cores, running at the same speed as LP-E cores but at one-third the power consumption, double or quadruple performance (single-threaded and multi-threaded, respectively).
Intel’s new thread director allows Windows to create containment zones, maintaining most workloads on Skymont E cores, which is crucial for Lunar Lake’s battery efficiency. Hyper-threading technology has been eliminated, as the new E cores are compact and powerful enough to render it unnecessary. This year’s E cores outperform last year’s P cores, with a 20% improvement in single-thread performance, and the four Lion Cove P cores offer a 14% IPC performance boost.
The Compute Tile also integrates the latest Xe2 GPU, fourth-generation NPU, and IPU. The Xe2 GPU enhances gaming and graphics performance by 1.5 times and boosts AI throughput over 3.5 times, delivering up to 67 TOPS of compute power. The NPU, doubling the hardware from Meteor Lake, increases memory bandwidth by 100% and clock speed from 1.4GHz to 1.95GHz, achieving up to 48 TOPS and 2-4 times overall performance. The IPU offers superior camera experiences with lower power consumption.
The Platform Controller Tile, built on TSMC’s N6 process, features an integrated security engine, upgraded connectivity suite with Wi-Fi 7.0, Bluetooth 5.4, PCIe Gen 5 and 4 ports, and Thunderbolt™ 4 ports. The Compute Tile uses TSMC’s N3B process.
Lunar Lake, set to ship in Q3 2024, will also include an AI PC development kit similar to a Mac Mini.
Intel CEO Pat Gelsinger, during his keynote at Computex 2024, took a direct jab at Nvidia’s Jensen Huang, countering Huang’s claim that traditional processors like Intel’s have lost relevance in the AI era. Gelsinger emphasized, “Unlike what Jensen would have you believe, Moore’s Law is alive and well.”
Gelsinger compared the current AI revolution to the internet 25 years ago, predicting it will drive the semiconductor industry to a $1 trillion valuation by the end of the century.
