 For starters, check out my video on the #RaspberryPi 5, it goes through _everything_ in more detail: https://www.youtube.com/watch?v=nBtOEmUqASQ #Pi5 
 The Pi 5 is at least 2x faster than the Pi 4 in every meaningful way: WiFi, microSD, USB bandwidth, CPU, GPU... though it still sticks with 1 Gbps Ethernet (but with PTP now!)

 The board includes the first custom silicon to hit an official Raspberry Pi SBC, the RP1 chip, which is a 'southbridge' between the BCM2712 and the rest of the IO. It has many tricks up its sleeve—expect to hear more about them in the coming months!

 There are also new battery, fan, and UART connectors, as well as a new power button, exposing some very handy quality of life improvements. This is the first Pi that's really comfortable being your tiny PC.

 There's also a new Active Cooler and case with improved airflow and a much quieter PWM fan. These are both huge upgrades over what came before, and allow the BCM2712 to run forever without throttling.

 I tested a TON of stuff on these boards, most especially the new PCI Express connector on the #RaspberryPi 5—check out my #Pi5 blog post for more on that! https://www.jeffgeerling.com/blog/2023/testing-pcie-on-raspberry-pi-5

 @3ddab33a That’s looking *very* thorough, with one exception: energy efficiency/power consumption are not covered 🤓😅

(That’s the first thing I want to know for 24/7 candidate devices.) 
 @66bd66f8 I do have a bit in the video, I didn't go in depth in the blog post (lack of time, ugh!). It's 1.8W idle with the official PSU. Sometimes more if you use a 3A PSU instead, which is counterintuitive... but what I measured. 
 @3ddab33a I'm a bit curious how it compares to the really soon coming Turing RK-1. Any chance you have any to compare? 
 @6a5fe6b6 I hope to... ordered RK1 to test. 
 @3ddab33a will you be covering this in a video as well? 
 @3ddab33a Is the case compatible with the active cooler or is it one or another? 
 @3ddab33a they pretty much included everything I've been asking for. This may be the perfect Pi! 
 @3ddab33a I’m unreasonably excited for the UART connector. I should be excited about PCIe! But no, giddy about an easy serial connection. 
 @e3b10963 lol "how do you tell a dev from a typical user"

"show them a dedicated UART port and see how they react" 
 @3ddab33a Well, I do work with Ampere Altra servers at my day job. Pretty soon I’ll even be managing the projects to support next gen processors like Ampere Siryn, etc.

So I’m wondering things like what level of SystemReady the rpi5 supports. 
 @e3b10963 I asked about this in May—they aren't (yet) interested in pursuing SR support. I have expressed my interest in them getting there, but it's not a market demand from the majority of customers at this time.

It'd be so cool to have SR SBC though! 
 @3ddab33a and still no usb pins for hats.

Those usb-to-usb dongles will still be in use. 
 @a06711c5 Wish they'd grabbed some GPIO pins and put a standard USB 2.0 header on there at least, ah well.

Or maybe a future revision with more FPC PCIe connections delivering USB 3. 
 @3ddab33a Does this mean we'll have to buy new cases and stuff? I hope the m.2 SSD cases don't take a year to release. 
 @fc52de53 For some yes; I know a few case manufacturers are already working on a revision (I would love to see Flirc make a passive heatsink case!) 
 @3ddab33a The battery is an interesting upgrade. And easy UART is always great. 
 @7f5ef107 Haha true, but I still like the new header for the convenience. 
 @3ddab33a great cover up! quick (dumb?) question: will I be able to just pop a raspberry pi 4 sd card into the new 5 gen and get everything working as soon as it boots? a drop-in replacement basically? 
 @354783b1 Yes...ish. As long as you keep it updated—Pi 5 requires Bookworm (version 12) and has to have the right dtb file in /boot for the Pi 5 to boot properly.

I still recommend re-flashing though :) 
 @3ddab33a so i should update the current Pis, fresh install raspberry os on the pi 5, copy its /boot folder into the pi4 sd cards and i’m up and running? 😬 
 @354783b1 It _should_ be that simple, but you'll have to upgrade from Bullseye to Bookworm on the Pi 4, and that could cause its own issues... 
 @3ddab33a 
Christopher Barnatt [ExplainingComputers] also has posted his video on #RaspberryPi5
https://youtu.be/9hYfQ7bRgZg 
 @730d71d5 Just watched it! 
 @3ddab33a Thanks for the rundown. What stands out for me though is the weird choice for a rather wasteful 5V/5A power delivery. Wouldn't it have made more sense to use USB PD with say 12V/2.1A at that point? I guess the 'trading efficiency for cost' compromise also applies here if it is that much more expensive to implement. 
 @3bd42c0d Yes, though I'm guessing that's more to save on BOM/board space for stepdown voltages. Maybe they'll go to 12v for a new revision someday, I'd be happy about that.

Note their PSU provides 12v/2.25A... 
 @3ddab33a ngl I’m kinda sad about it not having the audio jack 
 @a7c4e985 Me too :( 
 @3ddab33a great video Jeff, many thanks for relief from my usual doom scrolling over worry about Ukraine.  Very glad to see you getting one of the first!
