The Pi 4 2GB cost $45 at launch. Compared to the original, though, it has eight times the memory, 10 times the I/O bandwidth, four times the number of pixels on screen and dual-band wireless networking. As the company notes, thanks to inflation, $35 in 2012 is equivalent to nearly $40 today. So effectively you’re getting all these improvements, and a $5 price cut. This is a permanent price cut, with the 1GB version remaining at $35, so opting for the larger memory variant is pretty much a no brainer.
