Intel Panther Lake Processors: What the Latest Leak Reveals

Recent leaks have shed light on Intel’s upcoming Panther Lake processors, offering a glimpse into the company’s next-generation CPU lineup. As the first major product built on Intel’s advanced 18A process node, Panther Lake is poised to deliver significant improvements in both power efficiency and performance. These new chips are expected to form the backbone of the Core Ultra 300 series, which introduces a refreshed branding scheme and enhanced integrated graphics capabilities.

Core Ultra 300 Series: New Naming and Enhanced Graphics

The Panther Lake family will be available in two main categories: Panther Lake-H and the lower-power Panther Lake-U. Both lines will adopt the Core Ultra 300 series branding, with select models featuring an “X” suffix. This X designation signals a boost in integrated GPU performance, with up to 12 Xe3 cores—making these processors well-suited for demanding graphics workloads and content creation.

Panther Lake-H: High-Performance Mobile CPUs

The Panther Lake-H series targets high-performance laptops and mobile workstations. The top-tier Core Ultra X9 model is expected to feature a hybrid architecture with:

  • 4 Performance (P) cores
  • 8 Efficiency (E) cores
  • 4 Low Power Efficiency (LPE) cores
  • 12 Xe3 GPU cores

Other X-series models, such as the Core Ultra X7 and X5, offer similar configurations, with the X5 slightly reducing the number of E-cores and Xe3 GPU cores. Here’s a breakdown of the leaked Panther Lake-H SKUs:

  • Core Ultra X9 388H: 4 P-cores, 8 E-cores, 4 LPE-cores, 12 Xe3 GPU cores
  • Core Ultra X7 368H: 4 P-cores, 8 E-cores, 4 LPE-cores, 12 Xe3 GPU cores
  • Core Ultra X7 358H: 4 P-cores, 8 E-cores, 4 LPE-cores, 12 Xe3 GPU cores
  • Core Ultra X5 338H: 4 P-cores, 4 E-cores, 4 LPE-cores, 10 Xe3 GPU cores

The standard Panther Lake-H lineup, without the X suffix, includes:

  • Core Ultra 9 375H: 4 P-cores, 8 E-cores, 4 LPE-cores, 4 Xe3 GPU cores
  • Core Ultra 7 355H: 4 P-cores, 8 E-cores, 4 LPE-cores, 4 Xe3 GPU cores
  • Core Ultra 7 345H: 4 P-cores, 8 E-cores, 4 LPE-cores, 4 Xe3 GPU cores
  • Core Ultra 5 325H: 4 P-cores, 4 E-cores, 4 LPE-cores, 4 Xe3 GPU cores

Panther Lake-U: Efficient Performance for Thin and Light Devices

The Panther Lake-U series is designed for ultrabooks and other thin-and-light devices, focusing on lower power consumption. These chips feature fewer cores, with an emphasis on efficiency:

  • Core Ultra 7 360U: 4 P-cores, 0 E-cores, 4 LPE-cores, 4 Xe3 GPU cores
  • Core Ultra 5 350U: 4 P-cores, 0 E-cores, 4 LPE-cores, 4 Xe3 GPU cores
  • Core Ultra 5 340U: 4 P-cores, 0 E-cores, 4 LPE-cores, 4 Xe3 GPU cores
  • Core Ultra 3 320U: 2 P-cores, 0 E-cores, 4 LPE-cores, 4 Xe3 GPU cores

What to Expect from Panther Lake

While detailed specifications such as power configurations and clock speeds are yet to be officially confirmed, the rumored launch date is set for October 9. Panther Lake’s combination of Intel’s 18A process technology, hybrid core architecture, and upgraded integrated graphics positions it as a significant step forward for the company’s mobile processor lineup. As more information becomes available, Panther Lake is expected to set new standards for performance and efficiency in the next generation of laptops and ultrabooks.
