Helio g99 is actually helio g90t from 2019 found in the redmi note 8 pro. When it was new it used to be lightning fast based on YouTube speed tests. Today it's still okay, for daily usage i see no difference between infinix hot 20s, poco x3 nfc and poco x6 pro. All phones are fast. The difference is only when i play games. The x6 pro can handle higher graphics settings and more resolution without lag.
