The new Mediatek processor (64 bit) is highly capable than the previous generations of Mediatek.
It is very fast and snappy even comparable speed with the famous Qualcomm Snapdragon in term of raw processing power, but GPU used in Mediatek SoC is never come close to Qualcomm's Adreno Graphics.
And yes, Mediatek always having trouble with little things where Qualcomm at best.
Mediatek struggle in searching and locking GPS that makes navigation a little bit slower and harder.
Users are reporting problems with Waze navigation app. Unsable. Meizu and Mediatek are working on it.
As of updates, I'm not sure about now. But back than with previous mediatek SoC doesnt seem to have great after sale updates and loyality.
But no doubt, Mediatek is getting better than ever.
T
he SoC in M1 Note is already using the latest and up to date tech.
