I also noticed that. It's only ~280 megabits so seems a bit dishonest to call it gigabit. I guess what they mean is "gigabit ethernet standard" i.e. 1000BASE-T. Also how does it act once its internal receive buffer is full? Is it possible to get the sender to slow down, or does it have to start dropping frames? Will important things such as ARP broadcasts and DHCP requests just risk getting lost?

There is nothing dishonest about their announcement: they are explicit that speed is limited by the USB bus: > 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. Followed by a table showing 315Mb/s bandwidth, three times that of the 3B but a third that of full-speed Gigabit. And this isn't tucke…

The article yes, not the technical specification chart that is probably what most people see before buying it.

Didn't they already have pxe support on the Model 3B? This is just a bug fixed version (and enabled by default).

Yup. It's somewhat nontrivial though: https://www.raspberrypi.org/documentation/hardware/raspberry...

That documentation you've linked to is just very thorough, there's not that much to it. U-boot doesn't appear to be much simpler so I don't see the point in it, but maybe I'm missing some extra features it has?

But PoE isn't actually built-in to the Pi, it requires an external hat, purchased separately, and using a PoE hat has been possible on previous versions, yet they decided to announce it now, it's confusing.

They are not announcing PoE now. It is listed next to this particular model's features. The new/updated functionality is even bold (and power over ethernet is not).

I'm aware of the fact, it was just strange how they announced it in the video [0], as if it was a new feature. PoE has been possible on previous versions with a PoE hat aswell, so nothing really new.

Weren't previous PoE hats just ethernet splitters that also had a 5V output to the Pi rails, but still required another Ethernet cable to connect to the Pi's actual Ethernet port?

I'm a big fan of the Raspberry Pi community in general and have used it for multiple applications over the years; most recently as a media center TV box. However, the hardware now feels old and I wish for more of an update from the Pi foundation. If anyone hear is looking for a true upgrade on the Pi, try the ODROID C2, it's years ahead of the Pi in terms of performance.

The XU4 from Odroid is even better than the C2. There is virtually no reason to get the C2 now.

I agree, the XU4 is way better than the C2.

> There is virtually no reason to get the C2 now

I disagree with this though. The price difference between the two isn't insignificant.

If someone intends to deploy hundreds of devices for an IoT application the price difference between the 2 would be one of the reasons to choose the C2; the other reasons would be size and heating problems.

To me, that makes a lot of sense. Having only one architecture to support and one image to rule them all across the product line is quite a great thing to have. The other day, there was a person who had a "reddit gold" bounty for the first person who can help them get the Pi 0 online. The person basically couldn't get the Pi Zero on the wireless network. They had no USB-OTG adapter or mini HDMI adapter they could use…

Yes, but then promoting the Raspberry Pi as "64 bit product" seems almost gimmicky to me. Ok, you switched to an AArch64 chip, but that was simply because it's what your supplier was producing at that time. It makes no sense to me to promote a feature you don't support or make use of, if not for simple and pure marketing reasons.

That there are other OSes that do support it mean that it is a feature.

I'm still waiting for an inexpensive Linux board with proper sleep support. Suspend, hibernate, etc., and come back within milliseconds instead of dozens of seconds, and under $30 USD.
