Intel Panther Lake lineup leaks: 12 mobile Core Ultra chips with stronger iGPU tiers

Intel appears to have suffered a major leak: almost the full Panther Lake lineup has surfaced—twelve chips split across three series. The specifications point to a serious push on integrated graphics, especially in the new Core Ultra X variants.

The standout change in the Core Ultra X 3_8H line is a more capable iGPU; notably, the final digit in the name now signals the graphics tier, which suggests a clearer read on performance at a glance.

Core Ultra X 3_8H:

Core Ultra X9 388H (4P, 8E, 4LPE, 12 EU Xe3 iGPU), TDP ~45 W

Core Ultra X7 368H (4P, 8E, 4LPE, 12 EU Xe3 iGPU)

Core Ultra X7 358H (4P, 8E, 4LPE, 12 EU Xe3 iGPU)

Core Ultra X5 328H (4P, 4E, 4LPE, 10 EU Xe3 iGPU)

For those who don’t prioritize the iGPU, Intel is preparing a more modest Core Ultra 3_5H series, where graphics are pared back to 4 EU.

Core Ultra 3_5H:

Core Ultra 9 385H

Core Ultra 7 355H

Core Ultra 7 345H

Core Ultra 5 325H

And for ultrabooks and thin designs, the Core Ultra 3_0U family removes E-cores entirely in the name of power efficiency.

Core Ultra 3_0U:

Core Ultra 7 360U

Core Ultra 5 350U

Core Ultra 5 340U

Core Ultra 3 320U (just 2 P-cores!)

All signs point to Intel aiming to compete not just on CPU performance but also on integrated graphics—timely, given the momentum of Apple’s M-series and AMD’s Ryzen AI. If these reports hold, Panther Lake could mark Intel’s biggest mobile refresh in years.
