The new Raspberry Pi 3 B+ has just been released and it's got some pretty impressive specs
But I wanted to explore those a little bit further, especially the POE aspect of it
So stick around and listen to what I've got to say
It's TechWizTime
Hey guys, Johnathan here with TechWizTime where I create technology tutorial and review videos
In this video in particular I'm going to be looking at the new Raspberry Pi 3 B+
And more importantly the features that are included with this new board
So, just to give you a little overview this has got a faster CPU by about 200 megahertz. It went from 1.2 to 1.4 Gigahertz
The Wi-Fi module has been upgraded, It's also got a shield on there as well, so if you're putting this in commercial devices
You don't need that FCC regulation testing to make sure that it's not going to interfere with other devices
So that one's been upgraded to AC which is five gigahertz
The other feature is the ethernet has been upgraded to Gigabit Ethernet, however
It's not true gigabit
And we'll go over that a little bit more, in a moment
And the other feature that I wanted to touch on a little bit later was the POE aspect of it
Now there's some extra pins there for POE
But this device is only POE ready
And I'll explain that a little bit more later
So first up off the bat is the CPU and that's been upgraded to 1.4 gigahertz
And if you check out my buddy ETA Prime's video here
He's overclocked that to 1.57 gigahertz, so
For those looking to squeeze a little bit more out of this
Check out his video
So with the extra 200 megahertz in their processing power. This is going to make things run slightly better
It's not going to be like huge leaps
But it's going to run a little bit better and in terms of, say, Retropie with emulation
You may if lucky see a couple of extra frames. I don't think it's going to jump up too much
I haven't had a chance to test that out yet, but there may be some other videos out there that have
So that's the CPU out of way, the GPU is still the same, so there's no change there, so it's not going to really affect
Emulation or gaming on this device
But next up is the Wi-Fi. I've check out a few other videos out there of people doing the Wi-Fi test with the AC 5 Gigahertz speeds, and
I guess the limiting factor here is that the SD card slot is still using the USB 2
Chipset
So your maximum read and write speeds out of that MicroSD Card are going to be the limiting factor here
And that goes also for the Ethernet port which has been upgraded to Gigabit speeds here
Again that is using the USB 2.0 chipset, so
The data is in a full
Thousand megabits per second. It's actually limited to around 300 megabits per second
Which if you wanted to roughly convert it. And it's not right because it's 8 bits and all that sort of thing, but, 30 megabytes per second
Which again is roughly the speed of what you're going to get out of the micro SD card slot, so
It's it's better than the hundred megabits per second
But it's nowhere near the gigabit per second speed limit that we're looking at
With other devices that could be using the USB 3 chipset
Now the last thing that I want to touch on here was the POE aspect of this board
Now POE is Power Over Ethernet and the reason why this is really exciting is because if you can power this device through the ethernet port
Then you don't need an extra Power Point
Or I mean power cord, sorry
So that's exciting in itself because if you've got a mid to high end router, or
I should say switch
Like an Ubiquity switch that supports POE
Then that means that you could be running anywhere from 4, 5, 6
Raspberry PIs just off ethernet cables
It supplies the needed 5 volt 2.5 amps so you're not going to be underpowered there
And it's a one cable solution so perfect for those that are running
Say for example
Not that you would but
Mining on a Raspberry Pi
Actually if you want to find a funny video you can find out Nova Spirit's video up here
On his attempts with mining with a Raspberry Pi and other single board computers
And he actually managed to squeeze a little bit extra out of the raspberry PIs so go check out his video
So that's the exciting aspect of POE, however, it's only POE ready
And what that means is that you will need an extra hat in order to get the POE working
So that had just attaches to those pins there
And it's going to set you back another
$15 or so, so
Overall you're looking at about a 50 US dollar device
That is POE ready
So I understand that they couldn't put the extra bits and pieces that the Hat has on there on this board
Hence why they've got the extra pins there, so you can quickly just go off that with an extra hat and away you go
So not bad, and it's something that I want to test out because I imagine something like
This device running via Ethernet. Sorry. I should say
And having a USB camera hooked up to it
That's you know a great way to actually
That's a really good idea because you've got the bandwidth then with the 300 megabits per second or Gigabit Ethernet
As well as Power Over Ethernet
So you just need to run the one cable directly from the device to your POE switch
And it's powered and ready to go
So that wouldn't be a bad test if you want to see something like that leave me a comment down below and let me know because
I don't know if it's something that you guys would want to see
But it's something in my mind that I think would be an interesting video, so let me know down in the comments
So overall the question is, is the Raspberry Pi 3 B+
Worth the upgrade over the Raspberry Pi 3?
If you're looking at it for say Torrent box or something like that which I've setup up here
Or something that can connect to a Wi-Fi network at the 5 gigahertz band then
Yeah definitely this is worth the upgrade and
If it'll fit in your old cases, then definitely. It's worth it
I do know there are a couple of cases out there, but you need to trim up or
They don't quite fit so just be aware that your old 3 cases may not fit the new 3 B+
Especially with those extra pins there for the POE
