Huawei MateBook Pro S Leaks: Sub-800g Weight and Kirin XE90 Chip Surface in Online Rumors

The Huawei Matebook X Pro 2024

A flurry of leaks emerging from Chinese social media has painted a detailed picture of Huawei’s upcoming ultraportable laptop, tentatively named the MateBook Pro S, which is expected to debut at the company’s next hardware event. The most striking claim comes from Weibo user 看山叔, who posted a photograph of what appears to be a MateBook-shaped lid resting on a kitchen scale.

The image, which you can view here, shows the lid—identifiable by its flat, minimalist Huawei wordmark—registering a weight of 798.0 grams. If accurate, this would represent a significant engineering achievement, as the current MateBook X Pro tips the scales at close to 980g. Shaving nearly 200 grams off an already featherlight chassis would position the MateBook Pro S as one of the lightest premium laptops on the market, rivaling the likes of LG’s Gram series.

Five Editions and a Rainbow of Colors

Beyond the weight reduction, 看山叔’s post outlines a comprehensive lineup that suggests Huawei is planning multiple configurations to cater to different user segments. The list reportedly includes Standard, Collector's, Anti-Peep, and Soft-Light editions, hinting at variations in display technology, privacy features, and perhaps even materials. For instance, the "Soft-Light" moniker could point to a matte, anti-glare screen option, while "Anti-Peep" might indicate an integrated privacy filter.

Memory and storage options are equally diverse, with the leak pointing to 16 GB, 24 GB, and 32 GB of RAM alongside 512 GB and 1 TB of SSD storage. This broad range—particularly the inclusion of a 24GB middle tier—suggests Huawei is aiming to offer more granular performance tiers, a departure from the more common 8GB/16GB/32GB jump. Color choices are said to include yellow, white, gray, purple, and black, a vibrant palette that would make the MateBook Pro S one of the most colorful devices in Huawei’s professional lineup.

Kirin XE90: A Familiar Heart Beats Faster

The hardware rumors extend beyond the chassis. A Bilibili account by the name of AAA魅魔荧師傅 has posted details about a new processor, the Kirin XE90, which is described as the brains of this upcoming machine. However, the account frames the chip not as a ground-up design, but as an overclocked, relabeled version of the existing Kirin X90.

According to the leaker, the Kirin XE90 retains the same fundamental architecture as its predecessor but features a revised core cluster with higher frequencies. The purported configuration includes:

  • Four cores at 2.45 GHz with 1 MB of L2 cache
  • Four cores at 2.1 GHz with 1 MB of L2 cache
  • Two cores at 2.15 GHz with 512 KB of L2 cache

This approach would be consistent with Huawei’s recent strategy of refining its in-house Arm-based PC silicon. The current Kirin X90, which debuted in the first HarmonyOS PC (now rebranded as the MateBook Pro), reused much of the Kirin 9010’s architecture, including an 8 MB system-level cache and a 128-bit memory bus paired with dual-channel LPDDR5-6400. A refreshed, higher-clocked version would deliver a modest performance bump without the development cost and risk of a wholly new microarchitecture.

Expected Availability and Market Positioning

Given the specificity of the leaks—down to memory configurations and lid weight—it’s highly likely that Huawei is preparing to officially unveil the MateBook Pro S at its next major product event. The timing aligns with the company’s typical annual refresh cycle for its PC lineup, which often coincides with its developer conferences or autumn hardware showcases.

If the 798g weight proves accurate, the MateBook Pro S will not only be lighter than its predecessor but also significantly lighter than many competing ultrabooks, which typically hover between 900g and 1.2kg. Combined with the HarmonyOS ecosystem and the promise of enhanced performance from the Kirin XE90, Huawei appears to be doubling down on its strategy of creating premium, tightly integrated devices for professionals and power users.

As always, these claims should be treated with cautious optimism until Huawei makes an official announcement. However, the convergence of multiple sources on key specifications—from the lid weight to the core clock speeds—suggests that the MateBook Pro S is poised to be one of the most intriguing laptop launches of the year. Stay tuned for more updates as we approach the event date.
