In early March, we exclusively revealed that Intel was preparing a new Panther Lake chip called Core Ultra X9 378H. Intel has now made this SKU official over the weekend. The new processor has appeared on Intel ARK as part of the Core Ultra Series 3 lineup.
On paper, the Core Ultra X9 378H is effectively identical to the Core Ultra X7 368H. Intel lists both parts with 16 cores and 16 threads in a 4P+8E+4LP layout, 18 MB cache, 25W base power, 80W maximum turbo power, and a 5.0 GHz max turbo clock. The iGPU is also unchanged, with both chips using Intel Arc B390 graphics with 12 Xe cores and up to 2.5 GHz frequency.
