Intel Panther Lake variants named

Intel is said to be preparing three variants.

Intel is set to launch its Lunar Lake series, followed by Arrow Lake, both of which should be part of the Core Ultra 200 lineup spanning laptops, handhelds, and desktops. Coming later are the Core Ultra 300 series, likely powered by Panther Lake and Arrow Lake Refresh. It is said that, similar to Lunar Lake, Panther Lake will focus on the mobile segment; however, it will span across U/H and P-series.

Leaker Jakihn has revealed that there will be three variants of Panther Lake, featuring different configurations of CPU and GPU cores. As a reminder, the Panther Lake series is said to feature Cougar Cove and Skymont cores, while the graphics are to be powered by Xe3 “Celestial” architecture.

Intel Panther Lake configurations (Performance/Efficient/Low-Power/Xe3-Cores)

• Panther Lake-U (PTL-U): 4P➕0E➕4LP➕4Xe3 15W
• Panther Lake-H (PTL-H): 4P➕8E➕4LP➕4Xe3 25W
• Panther Lake-P (PTL-P) : 4P➕8E➕4LP➕12Xe3 25W

The U-series will feature 4 Cougar Cove cores and 4 low-power Skymont cores, with graphics capped at 4 Xe3 cores. Additional details were provided by another leaker, @OneRaichu, known for reliable Intel information. According to him, one of the Panther Lake-H variants listed by Jakihn is actually a P-variant. The PTL-H version has an additional 8 Skymont E-Cores compared to the U-variant, with no changes to the graphics. Meanwhile, the P-variant is said to feature three times as many GPU cores (12 Xe3), which is a major upgrade and perhaps one of the most interesting designs of all Panther Lake models.

Jakihn weighed in regarding the die configurations, revealing the first schematics of the Panther Lake mobile package, which uses five different dies, two of which are dummy. The largest die is for the Compute (CPU/NPU), while the remaining are for platform/interfaces and the other for graphics.

According to leaked roadmaps, Intel Panther Lake should appear by the end of 2025, with larger availability expected in 2026.
