When Eben Upton, co-founder of Raspberry Pi, started talking about the Raspberry Pi 4 in February, it sounded like a huge performance leap over what had come before. He also promised it would still only cost $35. Today, the Raspberry Pi 4 launched for $35, boasting 3x the processing power of the previous generation.

This is the first Raspberry Pi to be advertised as a "complete desktop computer." It offers 3x the processing power and 4x the multimedia performance of the previous generation while adding the ability to drive two 4K displays at once. There's also Gigabit Ethernet and USB 3.0 connectivity included.

Upton explained, "The vision behind Raspberry Pi 4 is to make a rich multimedia PC experience accessible to everyone ... By offering a 'just right' level of performance for most users, we've been able to do this at roughly a tenth the cost of a traditional desktop PC."

There will be three models of the RPi4 made available, offering 1GB($35), 2GB($45), and 4GB($55) of RAM. The claim of a complete desktop computer comes from the fact the tiny board can now handle "super-fast file sharing to multi-tab web browsing and sophisticated video and photo editing."

If you would like a Raspberry Pi 4 today, then they're already available for purchase, but stock is sure to be limited so don't be surprised if you're left waiting, especially for the model carrying 4GB of RAM.
