The Raspberry Pi Blog announces:
Raspberry Pi 3 Model B+ is now on sale now for $35, featuring:
- 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
Alongside a 200MHz increase in peak CPU clock frequency we have roughly three times the wired and wireless network throughput, and the ability to sustain high performance for much longer periods.
Video announcement here.
FAQs:
- Not discontinuing earlier Raspberry Pi models
- Raspberry Pi 1A+ continues to be the $20 entry-level "big" Raspberry Pi
- Considering possibility of introducing a Raspberry Pi 3A+
- CM!, CM3 and CM#L compute modules continue to be available.
- Still using VideoCore
Now I am left to wonder how many amps the power supply wall wart needs to be.

It's not reality that's important, but how you perceive things.

Editor Ingo Storm posted some measurements in the forum of their article of the topic:

Quote: "Unter Vollast auf allen Kernen waren es 7,0 [RPi3+] zu 4,4 Watt [RPi3]. Das sind aber immer noch weit weniger als die knapp 13 Watt, die das Netzteil der Raspberry Pi Foundation liefern kann." Sum-up translation: 2.5W vs 1.5W idle without network, 3.1W vs 1.7W idle connected to switch, 7.0W vs 4.4W full load. Still far less than the works power supply (13W) can deliver.
That looks rather power hungry. I'm not too convinced of the progress made here.

Probably setting the CPU frequencies back to older model's will make it more manageable. This reeks of "let's push the clocks 200MHz and ignore the insane power increases".

14 watts is not much compared to what this device can at this price point.
You still have headway to power plugged I use devices.
Maybe a problem for battery operations, or clandestine installation, but who does that anyway?.
No, you are mistaken. I've always had this sig.

I bought an RPi3 to fit into my parents canal boat so they can watch movies. This would be a battery installation.

It's also an issue where the device is used in embedded. I'm know of a project that runs on AVRs, but may switch to something RasPi-like in the future. The power supply is near its specs and there's no space for more power supply without redesigning the case bigger. As we see, most of the power soak apparently is from the Gigabit PHY, and the main BCM can likely be kept at old levels with underclocking/undervolting. There's also the CM3 which is better suited to such tasks, and that has no PHY on board, so everything will likely be fine as-is.
The 3B+ CPU is a "B0" version of the BCM2837 - from the die physics of the core, there shouldn't be much of a difference. It comes with a heat spreader on the 3B+. The thermal figures are here:
https://www.raspberrypi.org/blog/raspberry-pi-3-model-bplus-sale-now-35/ [raspberrypi.org]
As we see, the Plus' throttle kicks in at 70degC, after about a minute on full load, but the temperature still rises quite linearly even after throttling. The media center users might not be happy, because their use case lasts longer than 60 or 500 s, and for them and others who need sustained load, bolting on a proper heatsink without the spreader would likely give a bit more W/K of disspiation.
So the main benefit of the plus is for interactive tasks, like web surfing and compiling.
