Intel has officially unveiled Panther Lake, its new family of processors under the Core Ultra Series 3 name. These chips introduce the company’s 18A manufacturing process — the first of its kind for Intel. This technology aims to significantly improve performance per watt, with Intel claiming up to a 40% boost in energy efficiency in specific scenarios, while maintaining a solid balance between performance and power use.
Key Features of the Core Ultra Series 3
The Core Ultra Series 3 processors are built on a hybrid architecture that combines high-performance P-cores, high-efficiency E-cores, and ultra-low-power LP E-cores designed for lighter workloads. Intel plans several configurations to target different device segments.
The first configuration is a compact 8-core solution that combines four P-cores with energy-efficient cores, paired with integrated Xe3 graphics featuring four Xe-cores. This model is designed to replace Lunar Lake in thin and light notebooks, focusing on a strong balance between performance and battery life.
The second configuration is more powerful, featuring up to 16 CPU cores with additional E-cores. It is aimed at high-performance laptops that currently use Arrow Lake-H, offering enhanced multitasking and computing capabilities.
Finally, the third configuration focuses on maximizing 3D graphics performance without relying on a dedicated GPU. It includes an Xe3 GPU with up to 12 Xe-cores, promising up to 80% better graphics performance compared to previous or competing integrated solutions. This improvement is further supported by Multi-Frame Generation technology, which enhances smoothness in complex gaming and rendering scenarios.
The most advanced versions of these chips will support LPDDR5X memory running at up to 9,600 megatransfers per second — a crucial feature to ensure sufficient bandwidth for both the CPU and integrated GPU.
Intel has also emphasized artificial intelligence integration, adding a new-generation Neural Processing Unit (NPU) dedicated to local AI tasks. This allows for improved performance in productivity applications and features related to Microsoft’s Copilot+ ecosystem.
When it comes to power efficiency, Intel claims up to 16 hours of continuous video streaming, thanks to the ultra-low-power cores and overall platform optimization.
Pricing and Availability
Pricing details have not yet been revealed, but Intel confirmed that the first laptops powered by the Core Ultra Series 3 will arrive in early 2026.
