Leaked: Xiaomi Book 14 Refresh Packs Intel Panther Lake and Arc B390 Graphics

Xiaomi appears to be preparing a refreshed Xiaomi Book 14, and early leaks suggest it could be one of the first thin-and-light laptops built around Intel’s next-generation Panther Lake platform. The upcoming model is expected to target the premium ultraportable segment, combining performance-focused internals with a remarkably lightweight design.

According to an early hands-on hint shared by a Chinese YouTube reviewer (@Bibalaptop), Xiaomi has reportedly sent over a laptop that’s believed to be the new Xiaomi Book 14 refresh. While full details weren’t disclosed, the implication is clear: Xiaomi is positioning this as a sleek, high-end 14-inch machine designed for people who want strong everyday speed without carrying a bulky notebook.

A separate leak from well-known Weibo tipster Digital Chat Station adds more hardware specifics. The refreshed Xiaomi Book 14 is said to feature a 14-inch display and offer configurations reaching up to an Intel Core Ultra X7 385H (also referenced in reports as Core Ultra X7 358H). Either way, the message points to a higher-tier Panther Lake processor option aimed at users who care about snappy productivity, multitasking, and more capable integrated graphics. The leak also mentions Intel Arc B390 integrated graphics, which suggests improved iGPU performance for creative work and lighter gaming compared to older integrated solutions.

For buyers who don’t need the top processor tier, Xiaomi is also expected to include a more mid-range configuration featuring the Intel Core Ultra 5 325. This could make the Xiaomi Book 14 lineup more accessible while still benefiting from the Panther Lake generation’s efficiency and performance upgrades.

Memory and storage details are also starting to surface. The laptop is rumored to support up to 32GB of RAM, which is a strong ceiling for a 14-inch ultraportable and ideal for heavier multitasking, content creation workflows, and long-term usability. Storage, however, may start at a simpler set of options, with early information suggesting configurations topping out at 1TB initially.

One of the most attention-grabbing claims is the weight. The leak indicates Xiaomi’s new Book 14 could come in under 1kg (about 2.2 pounds), putting it in true ultra-light territory. If accurate, that would make it particularly appealing to frequent travelers, students, and anyone who wants a highly portable Windows laptop without sacrificing too much performance.

Other specifications remain under wraps for now, but the fact that a unit may already be in the hands of a reviewer suggests an official launch could be approaching soon. If Xiaomi follows through with a premium build, Panther Lake performance, up to 32GB RAM, and a sub-1kg design, the refreshed Xiaomi Book 14 could become a standout option in the competitive 14-inch thin-and-light laptop market.
