For me,

• emulation of old games: I’m guessing that this faster clock speed and gpu will allow it to emulate even more platforms.
• interactive art projects: I’ve been wanting to do one that requires low-latency encoding and decoding of video streams and I’m hoping that this will allow me to do this faster.
• facial and body tracking: There might be some very cool applications that are now possible with Google’s mediapipe.

The Raspberry Pi 5 was announced on September 28, 2023.Improvements in hardware and software reportedly make the Pi 5 more than twice as powerful as the Pi 4. It comes with a processor designed in-house, a power button, and an RTC chip, among other things. The RTC chip needs a battery, which can be purchased, but it saves a Pi user the cost of the chip
