Huawei's last PC was powered by up to Intel Core i9-12900H silicon; however, its next might not. The company has allegedly developed a new processor of its own self-developed Kirin series instead.
The "X90" may or may not be the ARM-based chipset seen doing battle with the Apple M3 in an earlier leak, and might be optimized for PCs rather than smartphones.
Nevertheless, the computer in question might run the HarmonyOS software also found on the OEM's mobile devices and wearables (which might work out in terms of interoperability).
The new device's form factor is seemingly to be determined at this point, but is backed to be "ultra-high-end" in nature, and also to be "a bit fancy".
It is allegedly scheduled to debut in May 2025, possibly alongside other products such as the Pocket 3 but before others such as the Pura 80 series of next-gen flagship smartphones.
