Our favorite ATM card sized Raspberry Pi 4 from The Raspberry Pi Foundation just released 8 GB RAM variant with 75 USD price tag.
It is now available for pre-order on thingbits for around ₹6000 in India. It more expensive than 2GB and 4GB models but it packs more memory in the same form factor and packs more punch where more is needed.
Pi Foundation slipped 8GB varient in the beginners guide of the Pi 4 released last year along with Pi 4 B+ 1GB, 2GB and 4GB.
BCM2711 Chip used in the Pi 4 supports upto 16 GB of LPDD4 Memory but to install it in the board, there where was no 8GB memory available as a single package and Micron somes to rescue and supplied pi foundation with 8GB LPPDR4 Memory in the single package need for pi 4 as explained in official blog post.
