The HomePod mini 2 is equipped with 2GB of RAM supplied by SK Hynix, according to information confirmed by MacRumors. Apple does not include the memory capacity in the speaker’s technical specifications.
The figure is in line with the 2GB of RAM found in the S10 chip used by the Apple Watch Series 10, although Apple’s published specifications do not provide a HomePod mini 2 RAM figure.
