[iamdarkyoshi]

Quite an exciting launch from the Raspberry Pi team:

CURRENTLY ON PREORDER, just a heads up

Here are the highlights:

 

A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3× performance)

1GB, 2GB, or 4GB of LPDDR4 SDRAM

Full-throughput Gigabit Ethernet

Dual-band 802.11ac wireless networking

Bluetooth 5.0

Two USB 3.0 and two USB 2.0 ports

Dual monitor support, at resolutions up to 4K

VideoCore VI graphics, supporting OpenGL ES 3.x

4Kp60 hardware decode of HEVC video

Complete compatibility with earlier Raspberry Pi products

 

 

These specs look freaking awesome, can't wait to get mine. Also quite neat to see them sell 1, 2, oatmeal and 4GB models, for 35, 45, and 55$.

 

I'm not a fan of the micro HDMI ports though, I'd rather have seen stacked full size HDMI ports, but whatever.

 

I'd love to see where retropie goes with this model, maybe full speed high res N64? owo

Does anyone know if ethernet and usb still go over the same bus?

Would make an nice and cheap NAS otherwise.

[vanished]

I would like to have seen them focus more on implementing hardware decoders/acceleration for all common video codecs (vp9 in particular).  That would be a nice compliment to everything else listed.

Honestly with how slow gigabit LAN is, grandma's old windows vista core 2 duo can do fine with a NAS... Its what we use at work, my grandmother's old dell lol

 

The pi would be a hell of a lot smaller and power efficient though.

So looks like they are using seperate controller this time

"The Ethernet controller on the main SoC is connected to an external Broadcom PHY over a dedicated RGMII link, providing full throughput. USB is provided via an external VLI controller, connected over a single PCI Express Gen 2 lane, and providing a total of 4Gbps of bandwidth, shared between the four ports."

Thats why I want to use a pi. I still have my old gaming rig (i5 4690k and gtx 970) but that would use way to much power.

Thanks, probably going to order a 4gb one and try it as a plexserver as well.

Time to make an Arcade Cabinet I guess.

OMGOMGOMG I need that right now!

how about camera-in and encoder specs?! O_O

 

EDIT: USB-C SOCKET MASTER RACE (even if it's just for power!)

Apparently it can do type C OTG provided the pi is powered by other means. 

 

I think. I could have sworn it said that somewhere but now I can't find it anywhere...

They do not.

Source? And by other means I'm guessing you mean via GPIO.

I would say no.

In the picture you can see two smaller hubs near the ports, a Pi 3 only has 1.

Remember to buy a heatsink. Even just scanning libraries will push it into the 70C range.

[Video Beagle]

grumble..and I just ordered a 3

 

(of course i ordered a 3 cuz it's recomended for a class I'm gonna take cuz I hate not knowing what I'm doing on my Zero.....it makes sense in my head).

I have a 3b with heatsinks(came with the case), it barely makes a difference if you don't actively cool it. Furthermore it can handle the heat, it's designed like that. If not it will throttle down, but never had it happen to me except in the summer or with an OC.

[captain cactus]

*pop*

 

noice

[Lurick]

My question is, if I have a 3B and want to upgrade to a 4, can I still use the PoE hat from the 3B on the 4?

[cluelessgenius]

yes. finally an easy way to dual monitor this bitch. 4k is maybe a bit much for my taste but sure why not. if only they werent both miniHDMI all this dongle shit is anoying. on the pi zero its fine since thats more for small hardware projects not really that great for multimedia anyway but on the full size pi i wouldve really loved fullsize hdmi ports. maybe stacked or something idk.

 

the powerdraw though worrys me a bit. just the general trend the pi has experienced. more performance is nice but the pi to me has to be low power usage so you can pretty much leave it on 24/7. 5v at 3a means 15w and thats basically the tdp of a i5 4300U in for example a surface pro 3 or any other older-ish low power laptop and im not sure exactly but i would addume those pack more calculating power. of course you cant really compare that since the has gpios and what not but for some project where you only need a lower cpu working quietly on calculating shit or controling your home or doing whatever the choice between getting a pi and getting a used laptop does become harder to me. 

 

plus any non-wall-powered project becomes harder and harder. build a robot or drone or rc car or anything with a battery pack? well i guess a pi zero would do for those. but still im using a pi 3 b+ in the car and if the trend of more power omsumption keep going i might soon need to hook it up directly to battery or install a seperate fuse or some shit idk. i just think a pi should stay low power like 2A ideally.

 

type c is also nice to see. i just hope they reinforce the mount to the board a bit. i have seen more then one microusb port broken off over time from constant plugging and unplugging.

 

oh and ac wifi is nice i just hope the bluettoth isnt the low energy varient

Yes, in their blog post they say everything from 2 and upwards should still be compatible, including the PoE hat which is what they used as an example

[matrix07012]

Can't wait for it to be available here.

 

EDIT: Oh, it already is. Just not in the big retailers.

^THIS

 

I know there are other boxes running Android that can do this cheaply too, but always preferred the experience you got with the pi and libraelec/kodi etc... so might be time to retire my ageing nvidiaTV. And I can get more for my family too.

Looks like a really good update. Here are some benchmarks.

Some highlights:

• The new CPU is much more powerful. In Linpack the new Pi is 3-4 times as fast as the 3B+.
• The move from LPDDR2 to LPDDR4 has increased the memory throughput from about 2500MBps, to around 4200MBps.
• The GPU has been upgraded from a VideoCore IV to a VideoCore VI. In Quake 3 Arena, the performance has increased from 27.5 FPS to 41 FPS. That's around a 50% increase.
• Ethernet performance has also been given a massive performance boost. From around 240Mbps on the Pi 3B+, to around 900Mbps on the Pi 4.
• The WiFi on 5GHz (not 2.4GHz) has been slightly improved. In his tests, it went from 97.6Mbps (Pi 3B+) to 114Mbps (Pi 4).
• USB throughput has received a MASSIVE performance boost. The throughput when connecting a USB SSD went from around 20Mbps (Pi 3B+, and basically any other Pi) to over 300Mbps (Pi 4). That's over 15 times as fast.
• The microSD slot has been upgraded. The read speeds seem to have doubled, and the write speeds are around 50% faster.
•  

Also worth noting:

• The new board is significantly bigger than the other models, which means a lot of cases will be incompatible.
• It is 4 grams lighter than the RPi 3 B+ (46g vs 50g)
• The SoC is now 28nm instead of 40nm like the old one.
• The RPi 4 runs much hotter than the previous models. It might be a good idea to get a heatsink or maybe even a case with a fan if you plan on putting it under constant heavy load.
• The power consumption is up too compared to the RPi 3 B+. Both idle consumption (around 0.1w more) and load consumption (around 1w more).
• The current software does not support booting from Ethernet or USB, but that is being worked on. This is important because right now the USB and Ethernet are both significantly faster than the microSD slot.

According to the blog post, yes. The PoE hat is still compatible with the RPi 4:

Our Gigabit Ethernet magjack has moved to the top right of the board, from the bottom right, greatly simplifying PCB routing. The 4-pin Power-over-Ethernet (PoE) connector remains in the same location, so Raspberry Pi 4 remains compatible with the PoE HAT.

Just because it is rated for that power draw doesn't mean it will always draw that much. Initial benchmarks show power usage around 2W higher than the 3B so ~33% more. The rest will be split up between external devices.

 

For a more than two fold increase in performance this is a small price to pay, if you really need a lower power draw just lower the frequency.

 

I do admit though that they are beginning to reach the end of the acceptable power draw range.

can a Pi have the boot OS on a volume over LAN? o_o

 for example the thing has no USB disk or SD card attached, but has an ethernet cable connected to a PC that has a network shared volume for the PI's OS

Yes.

Yes

Here is a guide on how to do it.

https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/net_tutorial.md

 

 

It works by downloading the system image from a tftp server (which you configure yourself in your network).
