Intel's Core Ultra X9 378H, the quietest addition to the Panther Lake lineup, has finally landed in a shipping laptop. Lenovo has updated its Yoga Air 14 Ultra Aura in China with the new chip, making it the first OEM to put the part into a retail machine roughly a month after Intel slipped it onto the spec sheet.
The Core Ultra X9 378H slots between the Core Ultra X7 368H and the X9 388H, and Intel has confirmed that it is functionally identical to the X7 368H minus vPro enterprise features. That puts a 16-core Panther Lake CPU paired with the Arc B390 integrated GPU into a thin-and-light chassis, a configuration that has been drawing attention from Linux users tracking kernel support for Panther Lake graphics and the latest Xe drivers. Phoronix benchmarked the Arc B390 Panther Lake platform on Linux using Ubuntu 26.04 with Linux 6.19 and Mesa 26.0, finding the open-source Intel graphics stack in solid shape, with Linux 6.18 and Mesa 25.3 serving as practical minimums for full hardware support.
Lenovo's China-market configuration ships with 32 GB of RAM and 2 TB of storage. The Yoga Air 14 Ultra Aura is the regional counterpart to the globally available Yoga Slim 7i Ultra Aura Edition, which already runs on Panther Lake silicon and replaced an older Lunar Lake-based Slim 7i Aura Edition. A quiet global refresh of the Slim 7i Ultra Aura Edition with the X9 378H later this year would be a logical next step.
Lenovo has not announced pricing for the X9 378H configuration in China, and no global release date has been confirmed.
