The upgraded chip supports Gigabit Ethernet, resulting in performance improvement.
The Raspberry Pi Foundation today announced a new version of its flagship low-priced board computer called the Raspberry Pi 3 Model B+. To mark this occasion Raspberry Pi Foundation launched the new version small in size and affordable for DIY enthusiasts.
Power over Ethernet (PoE) wasn't supported on the Raspberry Pi boards until now. The wireless circuitry is encapsulated under a metal shield (the one embossed with the Raspberry Pi logo).More news: Jets working on deal with ex-Vikings QB Teddy Bridgewater

Selling for just $35, the UK-made machine has become something of a phenomenon, selling close to 18 million boards since the first Pi was released in 2012. It's certainly a nice aesthetic touch, but has also allowed the board to be FCC certified as a radio module, a move that should reduce future conformance testing costs. "While the USB 2.0 connection to the application processor limits the available bandwidth, we still see roughly a threefold increase in throughput compared to Raspberry Pi 3B", the blog post reads. The latter additions will be particularly important for people who use a Pi as a basis for Internet of Things devices (IoT). Raspberry Pi Foundation aims to launch its own dedicated PoE HAT that will generate the 5V needed to power this Pi model. USB mass-storage booting has also been enhanced. Yet, he notes that the new board consumes "substantially more power", and recommends a high-quality 2.5A power supply, such as the official Raspberry Pi Universal Power Supply. The revised processor carries model number BCM2837B0 and has a metallic heat spreader to improve thermal performance. The SBC is rated for 0 to 50°C temperatures. Other continuing interfaces include the MIPI-CSI camera links, as well as the 3.5mm 4-pole composite video and audio output jack.
In short, the upgraded Pi promises more speed and power. Mechanical drawings and schematics have already been posted.
