The Raspberry Pi 3 Model B+ (Fig. 1) is now on sale and I bought one two weeks ago. The main modifications are the followings:
- A 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU
- Dual-band 802.11ac wireless LAN and Bluetooth 4.2
- Faster Ethernet (Gigabit Ethernet over USB 2.0)
- Power-over-Ethernet support (with separate PoE HAT)
- Improved PXE network and USB mass-storage booting
- Improved thermal management

The Raspberry Pi uses now the LAN2515 chip from Microchip instead of the LAN9514 for Ethernet and the USB Ports.
If you are looking for some Benchmarking of the new model, Gareth Halfacree has some nice graphics on his website.
If you are planning to use a heatsink on the new model, please check that the new SoC packaging has a hole, and you shouldn't cover it. Some people are writing that the heat spreader (metal bit on the Fig. 1) reaches to dissipate the heat generated and you don't need an extra heatsink. But, if you are like me, and you are using the Raspberry Pi for (near) real-time applications, with data processing, you should use some additional cooling system. It goes really hot!. The PXE Ethernet Hat, which is coming soon, has a fan. It could be an option!
As usual on my last posts, I compiled the last version of the Preempt-RT Patched Kernel to test its performance on this new model.
