Earlier today Huawei held an event in Shenzhen where it unveiled the Mate 30 5G and Mate 30 Pro 5G for the Chinese market. Alongside those two handsets, the company set the date for the retail start of the Mate X - November 15. If you want a Kirin 990 version of the Mate X though you'll have to wait some more as Huawei will introduce the Mate Xs in March 2020.
Design-wise, the Mate Xs seems to be identical to the regular Mate X. On the inside though, the phone will pack the newer and more powerful Kirin 990 5G chipset. The Kirin 990 5G is built on the 7nm+ EUV process and comes with an integrated 5G modem as opposed to the external one used in the original Mate X and its Kirin 980. It also offers a more powerful NPU in addition to overclocked Cortex A76 and A55 cores.
Apart from the chipset, we don’t have any other official Mate Xs specs so we’ll have to wait for more details in the coming months.
A few months later: Huawei Mate X2 coming in July. Mate X2s coming in December. Yeah yeah...keep announcing your future phone.
Announce a successor before the first phone even ships. I can't see that strategy going wrong.
