Even worse, continued RAM shortages and inflation might actually mean that will have been a good price in a year's time.
greenavocado•1h ago
Every day I go to bed praying CXMT hurries the *$!@ up and dumps an ungodly amount of cheap RAM upon global markets
mschuster91•1h ago
They won't, no one will. Too much investment for too much of a risk of the bubble popping and yet another run of the boom-bust cycle that left the world with not even a handful of RAM makers in the first place.
jauntywundrkind•1h ago
I wonder so much what their initial capacity was (which ought to go up marginally, and what their expected capacity curves look like.

I would not expect them to dump cheap ram. That is a false hope. The world needs volume, massively more volume, and it feels like everyone else is going to take a sizable fraction of a decade to even start responding. Maybe perhaps possibly CXMT can scale fast, but they have many multiples to grow before they are more than a drop in the bucket.

It's also unclear when if they too will want to start stacking 12 then 16 then 24 rams atop each other, to sell chips that cost what multiples of what GPUs used to.

Keyframe•49m ago
if anything, pricing will be around the same. Difference will be in availability.

Cheapest mac mini I could spec out on the apple store right now is about $750, which if you consider how much more capable its M4 processor is than the pi, is a pretty good deal tbh.

Funny different purpose but I bought a 2017 Pixelbook put Ubuntu on it, great machine it was $80

giobox•21m ago
Similar situation, one thing I like the with the Pis design is you can throw PoE hats on them and build a whole home infrastructure system where the only thing that needs battery backup for power cuts is the main ethernet switch - all of the essential services, switches and wifi APs are powered downstream by their ethernet ports over PoE.

Makes making your key network services (VPN, firewall, DNS, NTP, home assistant etc) on battery backup very easy, as just one plug to the primary switch to keep powered, and my wifi/internet stays on when the power cuts.

I could use other devices, but 5 pis with PoE hats rack mount very cleanly in a single 1U row and passively cooled with no fan noise etc.

greenavocado•1h ago
LMAO what a joke. N100 mini PCs are a hundred dollars less and vastly more capable aside from GPIO.
happyopossum•1h ago
An N100 with no RAM is $100 less, but throw in 16GB of ram and now they’re $150+ more…

Unfortunately Radxa and Milk-V are almost completely out of stock and not much cheaper. If you need more than a microcontroller there's no circumventing the memory shortage at this point.

Kicking myself for not buying the Q6A at the beginning of the year (I wanted three and arace would only sell one per customer, but one would've been better than none).

Two months ago I bought a M4 Mini w/16GB and 512GB HDD for $599. Granted they're up to $799 right now, but a Rpi is now $350 when they used to be $35?

You're correct; they've jumped the shark.

havaloc•1h ago
Come on, a one gigabyte Pi is under $50. There's no plot lost, it's just expensive RAM. 2gb is $75. That's where Pi plays well.
Levitating•1h ago
Yet the Radxa Rock 4d[1] has 4Gb and is selling for 69 dollars.

[1]: https://arace.tech/products/radxa-rock-4d

xp84•1h ago
Four of those would be $280 though, so this doesn't seem hilariously out of scale with that.
Levitating•51m ago
But ram prices don't scale linearly. The 4Gb variant of RPi5 is $130.

Radxa does have a 16Gb board[1] on pre-order, coming in at $329. Though the Dragon Q8B appears to be quite a bit more capable.

[1]: https://arace.tech/products/radxa-dragon-q8b

xp84•44m ago
I don't think I have any beef with what you're pointing out - I was only saying that I don't think the Radxa products' pricing are demonstrating anything too shocking about the Rpi products' pricing.

I personally would probably choose one of those over a Rpi (but would probably still rather buy more off-lease Elitedesk G6 Minis, which is what I use for 'lil computer' projects)

hnlmorg•1h ago
I think people commentating here are missing the point. The cost of that pi is for the 16 GB of RAM. Which in fairness, is a lot of RAM for a device of that type.

You can still buy a Raspberry Pi on a budget if you don’t need that much memory. For example, the 2 GB model is $75.

okanat•46m ago
RPis get sold more to the businesses and startups that started with them in 2010s, rather than hobbyists now.

If you cannot negotiate a good deal with the big industrial silicon manufacturers but you want good up-to-date kernels, RPis are a perfect option.

There are SoMs or SBCs with other CPUs like NXP or MediaTek that has more or less mainline support. However, they ask more money. The kernel contributions are also a bit on the shakier side which requires spending expensive developer time to deal with kernel issues that the CPU and the board manufacturer missed.

binarymax•1h ago
The original vision IIRC was to provide a cheap computer for students in low-income families. You could plug into your TV at home and start learning.

Then the hobby community got wind of it and proceeded to buy out all the stock on every release (myself included, I still have one of every first 3 versions sitting in my cabinet)

xp84•1h ago
This is hilarious considering you can easily[1] get a whole ARM laptop with 16GB for $425 all day, and that will also include a screen, keyboard, trackpad, battery, and storage.

I first checked for Mac Minis and interestingly they are much closer to $650 for similar specs.

And obviously if Intel is fine for your use case, either the N100 type of mini PC or, my preference, an off-lease HP, Dell, or Lenovo USFF PC, would be like half that for a very capable machine.

So strange. I can probably sell my 4GB Pi 5 for about 40% more than I bought it for... 3 years ago. This isn't how computers are supposed to work, let alone Pis.

I get what's happening, but it's strange to see it happening.

Actually, could I sell it for ~10% less than someone would buy it new? Is there a market for used Pis? Maybe 30%, I don't know. That I can sell it for what I got it for at all is wild.

chrissnell•1h ago
My home cluster is built from surplus Dell Optiplex desktops that I got from BYU Surplus and added some RAM (before RAM price went totally bananas) and SSDs to. I spent less than the cost of one of these Pis to acquire all of them together.

I later added a large machine that I used to use as a Linux desktop, with a GPU and 64GB RAM, which I use for generating OpenStreetMap tiles.

xnyan•12m ago
> less than the cost of one of these Pis to acquire all of them together.

Before RAM went crazy, the Pi 4 was $75 for *8GB and $125 for 16GB.

Another consideration is heat and power consumption, I have an OptiPlex micro (also surplus) and power consumption is 8W-90W (standby versus peak), 5x-10x more than a Pi 4.

teh_klev•5m ago
> My home cluster is built from surplus Dell Optiplex desktops

I used to do this as well and this is fine if you're able to source cheap power. But I'm in the UK, electricity prices are insane and I can't afford to run this kind of setup any more.

schappim•1h ago
Some folks might have missed that memory prices on the whole are up [1] 90% since Q4.

The memory used by the Pi 5 is up 700% [2]!

Raspberry Pi are working the issue by releasing new memory variants that are cheaper[2].

Edit: You can still walk into a Microcenter and get Pi 5 16GB for US $289!

I’m surprised to see those legacy USB ports on a board where space savings is important. Do they do it for backwards compatibility with older cases and housings?

And am I correct to see that the USB-C only does power? How do you connect your pheripherals to this board?

CDRdude•55m ago
I think legacy USB peripherals are very common. Almost all of my peripherals are legacy USB; I think I only own a single USB-C peripheral. Old stuff still works, so I don't need to buy new ones.
retired•32m ago
Interesting. I don’t own any legacy USB equipment anymore, everything is USB-C now. I started phasing out my old equipment ten years ago and everything from the past five years has had USB-C as standard. Even my shaver chargers over USB-C.

I guess that the people who use $350 boards also mainly use USB-C. Unless you want to connect old hardware to it but I don’t see that use-case.

Not being able to connect my devices to this board is a blocker for me.

forty•37m ago
Looks like all the USB-A devices purchased over the past 30 years have not been trashed and some people still use them.
retired•30m ago
Understandable but I would have preferred a couple of fully functional USB-C ports and then have people use dongles for using old hardware on this board. Similar to using a serial adapter.

Who would've thought the $50 pi 5 I bought on a whim would be my best performing asset in the last few years
Aurornis•48m ago
$50 would have bought the 2GB model at launch.

The 2GB model is now $65, so don’t get too excited.

Aurornis•51m ago
The Raspberry Pi 5 uses LPDDR4X. Finding 16GB (128Gb with a small b) chips in this size is not common. That memory chip is at least $200, probably more, even at the scale that they’re buying them.

I’m glad they’re making it available for the rare cases where it’s needed, but for PR purposes it would have been better if they just discontinued the 16GB model until RAM prices came down. I’m getting tired of hearing “Raspberry Pi 5 costs $300” now from people who have no reason to buy the 16GB version.

The 1GB version works well for simple Linux shell work and embedded projects. It’s $50.

The 4GB version works well for GUI work. Let’s be real: It’s a slow device and not a desktop/laptop alternative in 2026, so 4GB goes a long way for the use cases where you want to do basic GUI work. $110 for the 4GB model (if you shop not at Adafruit)

EDIT: Adafruit prices are higher for some reason. 16GB Pi 5 is $305 on other sites.

throwaway81523•46m ago
This isn't exactly news, that model has been at $350 for a while.

It's not like RPi suddenly introduced a 16GB model at a ridiculous price due to having forgotten about low cost stuff. The 16GB model was originally $85 iirc. Then the memory shortage hit. They could either withdraw the 16GB model (maybe screwing over some people who absolutely had to have it) or raise the price for those with urgent enough requirements. They did the latter.

Me, I'd like to see some large MCU's (let's say a little above RP2350 / ESP32 level) with a few MB of memory, but with memory protection, like old fashioned Vaxes with that much memory. That would allow running multiprocessing OS's where the processes couldn't easily clobber each other like on the current stuff. Many programs don't require GB's of ram.

desireco42•41m ago
Pi even before these ram prices was getting expensive and kind of missing the point from my perspective. Definitely good to have them releasing new models.

What bothers me is that now you need cooling for some models, and obviously price is getting too high.

On the other hand... $50 for 1Gb version is excellent still. And you should be able to use it just fine.

schappim•8m ago
The US has a plethora of alternative authorised resellers who are lower priced:

https://www.raspberrypi.com/products/raspberry-pi-5/#:~:text...

because Apple goes in and buys out entire production cycles based on anticipated demand. Most infamously they got a year worth of TSMCs last new node - no one else could have it.

Usually, that gamble pays off, sometimes it does not (cough Apple Vision), and in some cases they get so many QC rejects that they can make an entire new product line on (financially) worthless scrap, that's how the MacBook Neo came to be - a bunch of iPhone SoC's that failed binning, I think in GPU cores.

schappim•1h ago
Two things to note:

1) Apple had long term contracts for memory which will run out. Afterwards it will be very interesting to see what they do.

2) RPi uses older memory that is much much more expensive to buy in the market as manufacturers have dedicated capacity to newer formats used by AI boxes for KV caches

edwardsdl•1h ago
The linked model has 16x the amount of RAM that $35 model had. You can still get a 1GB model for less than $50.

Rohansi•59m ago
These perform way better and have similar efficiency, too. Case, power supply, cooling, and storage are all included too. If you don't need GPIO then you don't need a Raspberry Pi. If you do then consider using a microcontroller (Pi Pico, ESP32, etc.) first.
edwardsdl•54m ago

It's useful if you need GPIO but not $350 useful. Nowadays you can get used office mini PCs with a 10th gen Intel and 16GB RAM for like $200 and they'll come with an SSD. No idea why anyone would buy an expensive Pi.
