Intel’s Arrow Lake and Panther Lake Laptop CPUs Leak: Next-Gen Core Ultra 200 & Core Ultra 300 Series

Intel’s upcoming Arrow Lake “Core Ultra 200” and Panther Lake “Core Ultra 300” CPUs for laptops have made their way into the spotlight through multiple leaks. Let’s dive into the details!

Arrow Lake Lineup

The Core Ultra 200 CPU family, part of Intel’s Arrow Lake lineup, will cater to various PC platforms, including desktops and laptops. These chips are segmented into four categories:

1. Arrow Lake-S (Desktops)
2. Arrow Lake-HX (High-End Laptops)
3. Arrow Lake-H (Performance Laptops)
4. Arrow Lake-U (Low-Power Designs)

Arrow Lake-HX: High-End Performance

The high-end Arrow Lake-HX “Core Ultra 200” CPUs feature 8 P-Cores based on the Lion Cove architecture and 16 E-Cores based on the Skymont core architecture. These chips closely resemble their desktop counterparts and maintain similar die configurations. Expect standard 14-core configurations with up to 6 P-Cores and 8 E-Cores, similar to existing Raptor Lake-P/H SKUs.

Arrow Lake-U: Low-Power Efficiency

The low-power Arrow Lake-U chips come with a 10-core configuration, including 2 P-Cores and 8 E-Cores.

Process Nodes and Graphics

Notably, the leak mentions the N3B process node for Arrow Lake-H, indicating that Intel continues to leverage TSMC’s process technology for its next-gen high-end laptop chips. The compute tile will use the N3B process, while the iGPU tile will be based on the N4 process.

Both Arrow Lake-HX and Arrow Lake-U CPUs will feature Intel’s graphics architecture:

• Arrow Lake-HX: GT2 tier graphics based on the Arc Alchemist Xe-LPG+ architecture.
• Arrow Lake-U: GT1 designs with Arc Xe-LPG+ iGPU.

Panther Lake CPUs

In addition to Arrow Lake, Intel’s Panther Lake “Core Ultra 300” CPUs are also in the spotlight. These chips, evaluated on reference platforms, are available in UH, UPH, and P flavors. Intel recently achieved “Power On” with PTL parts on the 18A node.

LPDDR5X Memory and More

Intel plans to incorporate LPDDR5X on-package memory for Panther Lake-U low-power SKUs, enhancing thin and light platforms. Unlike Lunar Lake, Panther Lake offers more flexible DRAM configurations beyond the typical 16 GB or 32 GB LPDDR5X capacities.

Recent leaks also confirm Panther Lake “H” SKUs with 12 Xe cores based on the Celestial graphics IP.

Release Timeline

Dell leaks suggest that Intel’s Arrow Lake-H/P/U CPUs are targeting an early 2025 release, likely around CES 2025. Meanwhile, Panther Lake CPUs are expected to debut in early 2026.
