Raspberry Pi Foundation Launches Raspberry Pi 5
It has been over four years since the release of the Raspberry Pi 4, and in that time a lot has changed in the maker board and single-board computer landscape. For the Raspberry Pi Foundation there were struggles with worldwide demand and production capacity brought on by the global pandemic starting in 2020, and plenty of new competitors came to the scene to offer ready to order alternatives to the venerable RPi 4. Today however the production woes have been assuaged and a new generation of Raspberry Pi is here; the Raspberry Pi 5.
Raspberry Pi 5 is being announced in advance of availability unlike every prior RPi device launch. Pre-orders are open with many of the listed Approved Resellers on RPi's website starting today but unit shipments aren't expected until near the end of October 2023. As part of this pre-order scheme, RPi Foundation is withholding pre-orders from bulk customers and will be dealing in single-unit sales for individuals until at least the end of the year, as well as running some promotions with The MagPi and HackSpace magazines to give priority access to their subscribers. Genuinely nice to see, considering how hard it was to obtain a Pi 4 for the average Joe over the last couple years. The two announced prices for the RPi 5 are $60 USD for the 4 GB variant, and $80 USD for the 8 GB variant; or about $5 USD more than current reseller pricing on comparable configurations of the Raspberry Pi 4.
The Raspberry Pi 5 incorporates entirely new silicon with improvements made to nearly every aspect of the board. Below, Raspberry Pi Foundation provides a list of key features that paint the broad strokes of all the changes made to the RPi 5:
The Raspberry Pi 5 hosts many hardware changes and even some compatibility breaking new interfaces; however, the RPi Foundation has headed off the possible issues this may cause for users with a slew of new I/O accessories to address these changes. First, due to the new high density "mini" MIPI connectors RPi 5 is launching with multiple lengths of adapters to allow the use of existing "standard" MIPI devices. These adapter ribbon cables come in 200 mm, 300 mm, and 500 mm lengths and cost $1, $2, and $3 USD respectively. Alongside these are a new POE+ HAT adapter launching in 2024 that supports the relocated PoE header.
A rather exciting change comes from the addition of PCI Express 2.0 on the Rasberry Pi 5, and the expansion options for "fast peripherals" this opens up. To take advantage of this, a pair of mechanical HAT adapters for M.2 devices and accessories will be launching in 2024. These allow for the use of standard 2230 and 2242 devices such as NVMe SSDs, third party WWAN, WLAN, and BLE adapters. Presumably M.2 breakout adapters could also work, such as those that split to USB or SATA, but we'll have to wait for the adapters to test. The first of the two adapters (like the prototype pictured below) supports so-called "larger devices" while the second adapter will follow the L-shape configuration of the PoE+ HAT and allow for M.2 devices to fit within the plastic case accessory.
With increased performance sometimes comes (slightly) increased power draw, and Raspberry Pi 5 can pull as much as 50% more power than the Raspberry Pi 4 in demanding tasks. Because of this, and because of enthusiasts that will want to overclock, a new $12 USD 27 W USB-C power adapter will be made available. RPi Foundation is quick to point out that the RPi 5 does not need this increased power to function, and the 15 W power adapter will still work. However, with the 15 W power adapter the RPi 5 will limit downstream USB current to 600 mA maximum to ensure that it has ample headroom for very demanding tasks that might have the board pulling its maximum power rating. This USB current limit can still be disabled by the user when using the 15 W power adapter, and RPi Foundation says, "Raspberry Pi 5 functions perfectly well with typical configurations of higher-power USB devices, and all but the most pathological workloads."
Finally with the inclusion of a real-time clock in the Raspberry Pi 5, an RTC battery will be made available for a $5 USD surcharge. Frankly I feel like this should come with the standard kit, but at least it's available as a first-party accessory. (Though wiring up your own with some spare wire, a 2-wire JST plug, 3 V coin-cell, and some heat-shrink isn't out of the question.)
If reading all that wasn't on your agenda today, you're in luck. Raspberry Pi Foundation's Eben Upton hosted an excellent short video overview of the new Raspberry Pi 5 just for you. Further blog posts talking about the Raspberry Pi 5 will be posted and linked to on the Raspberry Pi 5 main page in the coming weeks.

I'm sure it will be popular even with the higher cost of entry.
Are the A17, Snapdragon 8, Exynos, Mali, etc, better than this?
At the same time the A76 is up to 3x faster than the A72 in its predecessor
Also similar to the MTK Kompanio 820, but again only for the high performance cores.
Graphics side will be a lot worse.
Mali is an Arm GPU design which is now quite old and not use in any modern chips, but I guess the GPU will compare to something like that.
Broadcom doesn't share performance specs of the Videocore GPU.

I honestly do not understand some of the design choices made. Why not use USB PD for power, instead they have a proprietary 5V/5A power requirement, which is just plain insane.
Why do PCIe over a ribbon cable like this?
It's going to be really hard to attach to the carrier board due to the odd placement (by the camera input).The board shown above, is apparently not the final design, but it appears as if they were going to use the MIPI display output connector for PCIe, which would've been a smidgen better.
The fact the new chip requires active cooling to operate at full speed is just sad.
I can sort of understand the re-use of the same WiFi module, but at the same time it's quite old by now and could've been replaced by something better as literally no extra cost.
I also really loathe this form factor, it's awful for so many reasons, least not cooling now.
C'mon RPi foundation, start using pico ITX already, it's a well established industry standard.
Edit: I was wrong about the placement of the PCIe connector, but it's still a weird design choice.
The issue with the RPi 4 was due to component shortage related issues.
Now they have a custom PMIC that they can control, so they shouldn't have any major issues, unless the fab can't produce enough chips for them.
I suspect a dual-core with SMT based on Zen2 or above + 3-4CU would already be superior to the pi5's SOC in pretty much anything.
I have a really nice class D amp hat for my pi4 B hopefully will work on the 5. I use mine as a emulator station, which will be nice on the 5 with a small nvme ssd.
Phoronix has some benchmarks up. Tested against the RK3588S which has four Cortex-A76 and four Cortex-A55.

Having been involved in developing a few products based around Arm chips, it's really a lot of software side work that needs to be done and all of those devices have been headless, so it doesn't even take into account how hard it is to have fully working graphics on Arm platforms. Even the proprietary drivers are rarely released fully to the public and obviously can't be part of Linux due to it being open sauce.I can understand some of the requests, but it all adds cost.
Maybe we'll see a Pi 5 lite?5V at 5A is more like 25 W computer.See above. We're way past that now, as the RPi 5 is none of what you're describing.
After this step, I would expect running pretty much everything would be business as usual.Look up the benchmarks over at Phoronix. There can be like 30% performance difference with the cooler on. So yes, something is drawing all that juice.
