Huawei launched the P50 series a few months ago and equipped some models with a Snapdragon 888 against all expectations. It appears that may not be a one-off decision, if a new Mate 50 Pro-related leak is any indication.
According to leaker Digital Chat Station, Huawei is testing out a Snapdragon 898 for the upcoming Mate 50 Pro. The tipster clarifies that the Snapdragon 898 in testing is a 4G model, just like we saw on the Huawei P50 series. The chipset is said to bear the model number SM8425, indicating that it's a variant of the Snapdragon 898 (SM8450).
While the source doesn't name-drop the Mate 50 Pro specifically, it states that it is a business flagship. Huawei's Mate series is its business-focused lineup, while the P series focuses more on cameras. Supposedly, the device in question will land sometime in Q1 next year, which would be a deviation from Huawei's typcical release schedule for the Mate series. It also corroborates rumors from earlier in the year that the P50 would be Huawei's only flagship for the year.
