> they can't make it available to normal people I guess you haven't been looking recently? I can go to a local store and pick one up. It looks easy to pick up one online too. https://rpilocator.com/

I have and it is still a pain. Many websites still have limits on how many you can buy. The situation has improved but it is far from what your comment implies.

Many websites still have limits on how many you can buy.

For a hobbyist / individual, is that really a big deal? I mean, how many do you need at one time?

Anyway, the claim all along has been that supplies would be "back to normal" by the end of this year, and so far things seem to be tracking that way. If you look at rpilocator.com now, the entire first two pages are full of green lines, which is a DRASTIC improvement compared to just 6 months ago. And some of the major distributors are getting in shipments of 5,000, 6,000 at a time of some models and having them in stock for weeks on end. So one can clearly see that the situation is improving rapidly.

That said, I will make no claim one way or the other with regards to the question of whether or not shipping a Pi 5 is a "good idea" or not.

5v/5A seems weird. Can normal power supplies even deliver this? One of the big benefits of rpi has always been to reuse power adapters and isn’t that all PD standard today? Higher wattage PD chargers and powerbanks that I have here all work with voltages of 9/12/15 at 3A and 20V at up to 5A

USB-C chargers do this all the time. People run notebook computers off of USB-C. A quick Google search suggests they aren't hard to find: https://www.walmart.com/ip/Type-C-Such-Phones-Charger-Charge...

That doesn't fit the bill:

> Output voltage (four charging modes): PDO DC5.0V-3.0A or 9.0V-2.77A PPS 3.3-5.9V-3A or 3.3-11.0V-2.24A

5V output at 5A is pretty unusual.

I question whether it's wise to launch a new product before the supply chain issues which have plagued Raspberry Pi for years have been fully resolved. Granted, the situation has improved slightly over the past few months. But you will still find Pi 4s out of stock more often than not. The CEO said last year not to expect a Pi 5 in 2023, because they wanted to take the time to recover. Why the u-turn? https://www.the…

Or it's a great way to counter the shortage by instead offering a new product that uses parts more easily available. We'll see.

> I guess that is fair, especially with inflation nowadays. The accumulated inflation in the US since June 2019 is c. 17%.[1] This means US$ 55 in June 2019 is "worth" c. US$ 64.35 today. So it seems that you get a 4GB Raspi 5 for c. 7.25% less today. The "US Real Average Hourly Earnings" have increase by ca. 22% in the same period, from US$ 27.75 to US$ 33.82.[2] So an average person needs to work c. 12% less to buy…

Please stop using “average” for wage comparisons. It’s an utterly useless metric for showing if wages are moving or not. If you must use average, then you should remove the top 5% from the average.

We're not called Treasure Island for nothing.

True, it's called Treasure Island because of all the stolen treasure it holds.. but jokes aside (shouldn't be a joke) i'm going to have a friend pick up one for me in UK and send it over to ZA where pricing is so so much worse.

Why do people in text attempt to joke, then pull back on the joke, making it not a joke and simply wasting time with useless banter?

I see that the PR against the Raspberry Pi linux repo is out [0]. Interestingly they are introducing a BCM2712 defconfig with a 64k default page size. From the device tree [1] it looks like they've rolled their own IOMMU rather than using ARM's SMMU which is annoying. [0] - https://github.com/raspberrypi/linux/pull/5618 [1] - https://github.com/raspberrypi/linux/blob/9c75e5408c01cb7c65...

Interesting. Did the earlier Raspberry Pi Broadcom SOCs not have an IOMMU? If they did I would have expected the 5 to be compatible with older ones.

I'm fairly sure that none of the earlier SoCs had an IOMMU. It's of course possible that there was one hidden in the GPU or something, but nothing on the CPU side.

The point here is likely to pull the rug out from under scalpers' feet. With the Raspberry Pi 5 out in two weeks, all the held-back inventory of older models will be dumped, prices will plummet, availability will become a non-issue. In that sense it's a wise move.

On a similar note, I'm genuinely curious as to why Pi chose the "authorized reseller" model instead of selling them directly.

I'd be surprised if reselling through authorized sellers isn't much simpler and problem-free than selling them directly.

I also expect that using resellers ensures better odds of protecting the brand/project goodwill. Resellers deal with problems like "I paid a ton of cash for a board and it arrived late and/or broken". Support alone is a nightmare, and I recall that raspberry Pi struggled with PR when they started out. I vaguely recall Liz Upton being behind some ill-advised episodes that didn't improved Raspberry Pi's image and would get anyone other PR person sacked.

The Pi5 is slower than a Core i3 6100, does not support upgradable ram, does not support Pci Gen 3 let alone Gen 3 x16, no actual Sata 6, no upgradable sockets, etc. There are a TON of uses cases for a Pi 5...but only really if power co…

Someone buying used electronics on eBay has already decided that their time is worthless and the hardware doesn't need to be dependable out of the box. Which is fine, those are decisions a person could make, but it's just disingenuous to compare the value of one thing to another without taking the you are using someone's untested trash factor into account.

There are reasons to prefer a Pi over a used mini PC, but it is not reliability. The fact is that with Pis or PCs, _if_ you're still running after a week, you're highly, highly, likely to survive past the point of usefulness.

Reasons to prefer a pi over a mini PC - easy access to GPIO pins; small(er) form factor; power efficiency; lower weight; still cost if you can work with zeros.

Reasons to prefer a mini PC over a Pi - price to performance ratio is often far, far better; size is "good enough" for people just after a small computer (rather than an electronics project, POC, etc); you are, in fact, reducing ewaste.

In short, if you just need something to run Home Assistant or Plex on ProxMox or similar, you would find more reward in a mini PC than a Pi, particularly in performance.

The bias at play is that people see "old" and equate it with "bad performance". That heuristic only works when comparing like for like - yesterday's mini-PC to today's mini-PC.
