Xiaomi Book 14 Refresh Leaked: Panther Lake with Intel Arc B390 iGPU Coming Soon

Xiaomi appears to be preparing a significant refresh of its popular Book 14 laptop, with leaked details pointing to a premium thin-and-light design powered by Intel's latest Panther Lake processors. The new model, which seems to be launching imminently, will offer configurations featuring Intel's Core Ultra X7 358H CPU paired with the capable Intel Arc B390 integrated graphics solution.

According to reports from Chinese tech reviewers, Xiaomi has already sent units to content creators for early evaluation. YouTube reviewer @Bibalaptop shared that they received what's believed to be the refreshed Xiaomi Book 14, describing it as a premium system with a thin and light design. This early access suggests the official launch is likely just around the corner.

The most detailed specifications come from Digital Chat Station, a reliable Weibo leaker who reported on the laptop in late February 2026. The tipster confirmed the 14-inch form factor and revealed that the device will be powered by Intel's latest generation processors. At the high end, users can expect the Core Ultra X7 358H, a performance-focused CPU from Intel's Panther Lake lineup that comes equipped with the Intel Arc B390 iGPU.

For users seeking a more balanced option, the lineup will also include the Core Ultra 5 325, a mid-range processor from the same family. This tiered approach allows Xiaomi to target both performance enthusiasts and mainstream users with the same refreshed design.

Memory and storage configurations appear generous for a thin-and-light device. The laptop will reportedly support up to 32GB of RAM, providing ample headroom for multitasking and demanding applications. Storage options, however, seem more limited initially, with only 1TB configurations available at launch. For users requiring additional storage, Xiaomi may need to rely on external solutions like the Samsung T7 portable SSD, currently priced at $314.22 on Amazon.

One of the most impressive specifications revealed is the device's weight. Digital Chat Station reports that the new Xiaomi Book 14 will come in under 1kg (approximately 2.2lbs), making it exceptionally portable for a laptop with these performance capabilities. This featherweight design could position the device as one of the most portable premium 14-inch laptops on the market.

The inclusion of Intel's Arc B390 iGPU is particularly noteworthy. This integrated graphics solution represents a significant step forward from previous generations, offering substantially improved gaming and creative application performance compared to older Intel integrated graphics. For users who occasionally need graphics horsepower but want to avoid the bulk and cost of a discrete GPU, this could be an ideal compromise.

While complete details remain under wraps, the early leaks paint a picture of a thoughtfully designed premium laptop that balances performance, portability, and modern features. The combination of Panther Lake processors, Intel Arc graphics, generous memory support, and sub-1kg weight suggests Xiaomi is targeting users who need capable performance without sacrificing mobility.

Given that Xiaomi has already sent review units to content creators, an official announcement could come within weeks. The timing aligns with Intel's rollout of its Panther Lake processors, which began appearing in devices earlier in 2026. For users in the market for a premium 14-inch laptop that won't weigh them down, the refreshed Xiaomi Book 14 appears to be worth watching closely as more details emerge.
