It was the first product from the organization to come with 64-bit processing and integrated wireless connectivity, making it a popular option for the homebrew community.
This model comes with slightly faster 1.4 GHz quad-core processor in comparison to the 1.2GHz processor of its predecessor. These include the new processor's improved power integrity, packaging, and heat spreader, and internal clocking and voltage rule tuning.
The new Raspberry Pi 3 B+ comes with improvements in speed across the board, as the company promises to deliver "more processing and faster communications". It is available immediately. According to Raspberry Pi, it's sold more than 9 million Raspberry Pi 3 units and a total of 19 million Raspberry Pis in total.
While offering improved thermal management compared to previous Raspberry Pi incarnations, the board also retains numerous same features and capabilities of previous-generation boards such as its small mechanical footprint of 85 x 56mm, making it suitable for the current official Raspberry Pi case, as well as many other third-party enclosures available on the market today. Support for dual-band 802.11ac wireless LAN has been added to allow connections to 5 GHz networks.
The board also offers improved communications performance via Gigabit Ethernet over USB 2.0, delivering a maximum throughput of 300Mbps through the board's four USB 2.0 ports; as well as retaining the extensive 40-pin GPIO (General Purpose Input Output) header connector.

As of now, the foundation has revealed no plans to discount or end production of the older models. Further, the executive confirmed that there would be no change in the pricing of the earlier models. Another bonus is the board's co-creator Eben Upton says that the processor should be less likely to throttle its performance under heavy load-thanks to a heatspreader on top of the CPU.
