• Panther Lake CPUs will be manufactured on Intel’s 18A node, marking a major shift in Intel’s fabrication technology.
• It features RibbonFET transistors and PowerVia backside power delivery, enhancing power efficiency and boosting performance.
• More than 70% of the CPU’s components and chiplets (tiles) are built on Intel’s own in-house manufacturing.

2. New Core Architecture: Cougar Cove & Skymont

• Intel introduces Cougar Cove P-Cores (Performance Cores), offering better single-threaded performance and efficiency.
• The E-Cores (Efficiency Cores) use Skymont architecture, optimized for background tasks and power savings.
• The combination of these cores ensures better multi-core performance, making Panther Lake ideal for laptops and high-performance ultrabooks.

3. Intel Xe 3 "Celestial" Graphics

• The integrated GPU on Panther Lake is powered by Intel’s next-generation Xe 3 graphics (codenamed "Celestial").
• Small GPU configurations (4 Xe-3 cores) will be fabricated on Intel 3, while higher-end versions (12 Xe-3 cores) will be manufactured by TSMC on N3E.
• Expect better gaming performance, improved AI acceleration, and enhanced media capabilities.

4. AI & Machine Learning Enhancements

• A 5th-generation Neural Processing Unit (NPU) improves AI acceleration for Windows Copilot, video editing, and productivity software.
• AI-driven optimizations enable faster rendering, real-time upscaling, and enhanced power efficiency.

5. Memory & Connectivity Upgrades

• Supports DDR5-5600 and LPDDR5X-7467 memory, ensuring faster data processing.
• Integration of PCIe 5.0 and Thunderbolt 5 for faster storage and external device support.
• Expected improvements in power efficiency for longer battery life in ultrabooks.
