Intel adds another 16-core CPU with Arc B390 graphics

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.

The difference is in platform features rather than performance. Intel lists the Core Ultra X7 368H as vPro eligible , with support for AMT, Remote Platform Erase, One-Click Recovery, SIPP, Total Memory Encryption – Multi Key, and VT-rp. The Core Ultra X9 378H drops those features, although it still keeps ISM, VT-x, and VT-d support, which makes it look like a consumer-positioned version of the same silicon.

This brings us to the naming. This SKU  does not actually move above the Core Ultra X7 368H in clocks or graphics. The only Panther Lake X9 part that still sits higher on paper is the Core Ultra X9 388H, which boosts to 5.1 GHz instead of 5.0 GHz.

In other words, we should treat it as a renamed 368H without the business stack.
