Raspberry Pi is the most successful credit card size computer and it's flagship model just got better. The initial model came in 2012 and on March 14th 2018 the Raspberry Pi 3 B+ was released. The selling price has been kept more or less the same since the first one, so you can get the new updated version for around $35. The B+ takes the 2016 Pi 3 Model B and ups the processing power and Wi-Fi speeds, alongside some other minor tweaks. These little boards are cheap and have many uses, one of them being a retro games system emulator, and who doesn't want a little more power to run their favorite games? ;)
Hardware improvements from the Pi 3 to Pi 3 B+
Faster CPU
The Pi 3 Model B+ is based on the same quad-core, 64-bit processor, as the Pi 3 Model B. Like the Model B, the B+'s is based on a Arm Cortex A53 architecture. However, the B+ ups the speed of the CPU to 1.4GHz from 1.2GHz in the original Model B, an increase of about 15%.
Faster Wi-Fi
While the original Model B only supported 2.4GHz Wi-Fi, the Model B+ has a dual-band wireless antenna, supporting 2.4GHz and 5GHz 802.11 b/g/n/ac Wi-Fi. The 5GHz 802.11ac Wi-Fi has been found to be capable of about 100 Mb/s throughput in testing, more than double that of the 2.4GHz 802.11n Wi-Fi found on the Pi 3 Model B. The B+ also offers support for Bluetooth 4.2, an improvement over the 4.1 support found in the Pi 3 Model B.
Faster wired Ethernet
On top of the Wi-Fi upgrade, the wired internet also has a speed bump, courtesy of the board's new Gigabit Ethernet over USB 2.0 bridge, which ups the maximum throughput to about 300Mbps. Another plus for those using the Pi with a wired Ethernet connection is the inclusion of support for a Power Over Ethernet [POE] Hardware Attached on Top [HAT] board, which will add the ability for the Ethernet cable to power the board.
