content: Although on the one hand, I'm very excited that they are going to be releasing the new improved Raspberry 5 (the previous PI 4, was often plagued by severe shortages, because of Covid and things, through most of its release life).I'm a little bit disappointed, (although after-market add-ons and even official add-ons, are likely to resolve many or all of these things), they haven't, as standard addressed things like:Improved thermal handling, when under big CPU loads. (But it does look like they will be selling official solutions to that issue).Increasing maximum memory (RAM) to 16 GB or more. (But 8 GB is plenty for many things, even the 4 GB version, is usually perfectly fine).Giving eMMC storage options, to replace the potentially unreliable microSD cards.Putting some kind of M.2 slot, for SSDs, which are becoming so affordable with ever increasing capacities, that it would make a very nice addition.On the other hand. Prices seem to have remained rather affordable, and putting in some of my suggestions, could have increased the price too much, especially for some use case scenarios.I suspect, there will be (relatively soon), special after-market cases, which resolve the possible cooling issues and give it an M.2 slot, as well as maybe other features.It is possible an unannounced 16 GB version, is planned for the future.

content: The following video (Jeff Geerling), seems to be rather good (describing many of the improvements), giving lots of details and more, about the Raspberry PI 5.From the Video:It seems it can readily support M.2 drives, because of the built in, PCIe connector, via hats.It also seems that 16 GB RAM, is now possible, so may be released, some time in the future.

content: Sounds cool. Question is: what about price? "Similarly" spec'ed SBCs from competitors are in the > $100 range. Let's see what they offer here. Will they *really* manage the "$60 for the 4GB variant, and $80 for its 8GB sibling" price tag in the end? (Note that if you add VAT you'll end up in the $100 area anyway.)Other than that, unless I missed it, I think it would have been cool if they had integrated a RP2040, but I guess that if would have required an additional connector (re-using the "standard" 40-pin header to break out a number of RP2040 GPIOs would have made the thing incompatible with all the "hats" ecosystem.)

content: Quote from: beanflying on September 28, 2023, 11:59:49 pmWhat PCIe specification, can you get for a brand new, desktop PC, laptop or similar, with a brand new asking price of $60 to $80?Currently, AMD Zen 4 CPUs, seem to start at around > $200 for a 7600. in the UK. The motherboards cost a small fortune, as well.That seems to be enough PCIe, to give around 500 MB/s, which is fine for many things. I.e. It is similar to SATA speeds.Taking the relatively low price, tiny size and relatively low power consumption (a video seems to measure around 6 watts, under a full load application), it doesn't seem too bad.It seems to be a lot better than previous Pi models.

content: PCIe 2.0x1 is on par with USB3.1 (without checking) so the point is while 'nice' is is hardly a feature. You may as well go buy an external USB adapter. Given they rolled custom IO silicon this is shortsighted.It is not about putting the product down at all but just technically it doesn't deserve to be overhyped for performance it doesn't have against other offerings already in the market.The clearly tried the PC hardware review embargo thing here as every vaguely related SBC talking head on YouTube got one to promote pre orders.

content: Quote from: SiliconWizard on September 28, 2023, 08:20:12 pmWhat do you mean by that? You can preorder one right now, for the advertised price. And I have -- see my order confirmation below. The store (Pimoroni) told me it will ship around October 23. No UK VAT was added and as it is under NZ$1000 I won't get charged NZ GST either. Tracked shipping to NZ added £12.50 (or untracked for £10).QuoteAccording to Yearling the RP1 shares a lot with the RP2040, is used to drive the GPIO, and is probably user-programmable with code running with the Pi "off".

It has been a long time since you can get a pi for the advertised price in a timely manner. Let's click reload on rpilocator.com and roll the dice again!And even now when supply has eased, the places showing the pi foundation official price are still typically limiting you to qty 1, and of course, full shipping cost each time.Sometimes something can be technically true without being usefully true.

content: Quote from: beanflying on September 29, 2023, 12:42:05 amI think, by spending relatively small amounts of money, here and there. The Raspberry Pi 5, could be improved, speed wise and in other respects.But, the team, seem to keep a very careful eye on the intended asking / selling price, so keep a very tight reign on such things, to keep the costs, sensible.As I see it. It is the reliable, long term availability, of a range (of at least one or more) of working operating systems, for these Raspberry Pi Boards, that makes them especially useful.There are plenty of potentially, cheaper (often) Chinese boards (e.g. via Ali-express). But it can be tricky, to get reliable (reasonably bug-free), operating systems, documentation, drivers and support, especially as the boards, get older.

content: Quote from: djacobow on September 29, 2023, 01:11:38 amTalking specifically about the Raspberry PI 5. It is fairly normal (if I remember correctly), for the initial release to have a very limited quantity available (sells out very quickly), and possibly limit customers to a maximum of 1. Until they have had time to ramp up production, and the demand settles down to relatively normal levels.

content: Quote from: brucehoult on September 29, 2023, 12:42:55 amI don't know how things work in NZ, nor the deal about this $1000 threshold. Over here in EU, we pay VAT on absolutely everything starting at the first cent.I went to the preorder page, added to cart and unsurprisingly got 20% VAT on top of the base price and shipping. Normal stuff. We just need to be clear about what a "price" means when we're talking with people from all over the world with different systems and different agreements between countries.Other than this tax thing (which is not specific here), as djacobow said. Prices announced at preorder time are one thing, prices once the product ships on a large scale may become another, and they are likely to further raise over time these days.QuoteNot really. Apparently the RP1 is the I/O controller they designed for the RPi5, it contains pretty much all I/O interfaces (USB, Ethernet, ... and yes, the GPIOs and some UARTs, SPI, I2C), but there is no indication that the GPIOs will even be programmable with something similar to the RP2040's PIO, and I doubt it at this point, but we'll see. Even if this is the case, a complete MCU beside the SoC would IMO have been a good addition, something other SBC vendors do offer, and something that would have made sense for a RPi. So, the RP1 is said to have been designed by the same team as the RP2040, but that doesn't mean that it is anything close to it and even less so that it actually contains a CPU core of some kind. So, this RP1 may be cool and a good idea for lowering costs and integration, but adding a RP2040 to the board wouldn't have hurt IMO. We'll see what this RP1 can really do.Other than that, there's still no sign of eMMC. What you get is still a microSD slot, and yes, M.2, except that only single lane PCIe as others have pointed out, and according to the product brief, there is no M.2 socket, so it requires an additional adapter to actually connect anything to it.Note that I'm not basing my first impressions on a video (that I haven't watched), but on elements read on the RPi's site itself.

content: Quote from: SiliconWizard on September 29, 2023, 01:43:36 amUntil a couple of years ago it was $400. The principle is that there is no point (other than punitive) in charging an importer VAT if the amount collected is less than the administration cost of collecting it.QuoteThat is unknowable. What I know is I have a legal contract for delivery, my bank app shows my credit card had been charged, and they are obligated to deliver the promised goods at the price agreed and paid.QuoteI know what the RP1 is. I am quoting what Yearling has said subsequent to using and reviewing the board and asking Raspberry Pi a lot of questions. He's good buddies with Eben and I'm sure gets his questions answered.e.g.https://news.ycombinator.com/item?id=37686458

content: I like the pi's and have used them in a lot of projects and even sold a couple of pi hats, but my love affair has mostly waned.This new device looks pretty good, perhaps I'll try it out. The main advantage is sticking with raspberry foundation hardware is that raspbian generally works and you will not be needing around with compiling kernel drivers or messing with device overlay files, as is a big part of my life on the rk3588 boards.That said, one thing that REALLY bugged me about this release announcement is that all the usual suspects had prerelease boards, which means they ALL have relationships with the pi foundation, and as far as I'm concerned, that makes their review close to worthless. Nobody who had a board today is going to say anything seriously critical about pi stuff because they know where their bread is buttered.There will be reviewers later who actually buy their boards themselves and whose living doesn't depend on suppliers' good graces, and maybe we'll see some honest reviews.

content: Quote from: djacobow on September 29, 2023, 02:03:04 amMost of them are only comparing against the Pi 4, true. But Yearling, at least, also showed benchmarks vs Rock 5 and Orange Pi 5 showing that they are up to 50% faster on many things. The RK3588S version of the Orange Pi 5 isn't much more expensive than the Raspberry Pi.Software and support-wise, it is definitely safer to go with RPF. I don't think I've seen any of the others playing Youtube 1080p as smoothly as the Pi 5 and that is the most make or break critical thing many consumers do with these boards.

content: Quote from: djacobow on September 29, 2023, 03:34:44 amIt might be manageable when you're at home but can be a real hassle in labs, offices, classrooms, etc... where you have a shared wifi network and have potentially many users with many devices. When raspbian shipped a default user, people would take advantage of that to write scripts to "make things easy" that would just poke the first pi device they saw on the network (assuming there would only ever be one) with the default creds and could easily get the wrong one when there were many and they all had the same user account.

That requires a unique hardware ID and extra manufacturing time steps but it's the way to go for consumer electronics.But the best option for the RPi is to use the raspberry pi imaging tool to write your SD card or USB boot device rather than buying a pre images SD cards. Then you can enable SSH, create a user account, and set a password.

content: Quote from: brucehoult on September 29, 2023, 02:50:50 amI'm waiting for a small RISC-V board with SMP full support and a couple PCIe that's a little better supported by Haiku/OS, then I'll definitely go back to dealing with it (even to develop a simple kernel driver for MGA chip, Matrox, dual channel), on the front line, so even if it were unstable or full of bugs, it would be fine.At the moment, however, I find the two MIPS boards from 1992 (R3000 32bit) and 1995 (R4000, 32/64bit) much more pleasing, one from IDT, the other from Algorithmics, things that have no { GNU/Linux, NetBSD, OpenBSD } support, and that's fine, as you program in assembly, because that's all you can do, but you relax more than using the last super powerful generation SBC for the same things you would do with your smartphone.I have never bought an RPI. I worked on a couple of Allwinner ARM/32bit SoCs, and on a MediaTek ARM/32bit SoC, and I was very stressed by the terrible level of both the firmware and the kernel.Well, comparing my experience with Allwinner and MediaTek: the second one is 5 times better!

content: Quote from: beanflying on October 01, 2023, 12:25:05 amI did some studying over the weekend and nothing makes an MMC or eMMC more reliable than a microSD or other SD card. The protocol is different so may be more suitable for things like in-place execution, but they both now rely on standard NAND flash technology. An eMMC is more accurately thought of as a MicroSD that can be soldered in place, so cheaper.

content: Quote from: David Hess on October 02, 2023, 04:37:37 pmThat is a very good, question.My understanding is that microSD cards, on previous Pi’s, had issues with damage to the data on it, sometimes so bad (in time), that the Pi would no longer, even boot from it. Especially vulnerable during power down. Maybe because previous Pi’s, had no power button.Also, microSD cards have a reputation of being (but NOT as bad as USB flash pens) poor quality (salvaged rejected flash chips). Especially really cheap, unbranded ones. Might be missing some of the features built into SSDs, which helps keep the data safe, such as wear evenly (levelling) and proper handling of things like data corruption (recovery).I’m not sure why, in comparison, eMMC is held in such high regard. Perhaps it has decent quality, long life flash, with a degree of similarity to SSD techniques.

content: It's because some SD cards (not quite all) are relatively vulnerable to being powered off suddenly, even when using a journaling filesystem.The power button won't do anything about it - it just triggers the shutdown/reboot/... menu when you are booted into Linux under a desktop environment, just a "hotkey" in other words. You could use the same shutdown option from Linux before.The handier part of it is not really about shutting down, but more about powering on. In previous versions, once shut down, the board could not be powered back on without power cycling it (pretty annoying). Now you can just press the button.

content: Quote from: MK14 on October 02, 2023, 08:24:26 pmSure, that was always part of the problem... but if you intend to keep a device on any extended periods of time, power failures are a reality you have to face. (and it's silly to think about spending the money it would take to put a reliable UPS in front of a $35 computer.)Also the problem is more than just file system corruption... it seems to actually damage the flash. My 3B has pretty consistently destroyed any card that's mounted if the power goes down unexpectedly -- any further attempts to read or write the card even on other devices end up in a death spiral of bad blocks and hardware errors.

content: Quote from: abeyer on October 02, 2023, 10:48:02 pmMy approximate understanding is as follows:Consider a high end, proper consumer SSD. Cheaper ones may lack some of these features, such as supercapacitors, DRAM etc.Behind the scenes, it has many data protecting / preserving mechanisms.Such as a supercapacitor, so if the power suddenly disappears, it can finish all writes and flush any cached write data, to the disk.A sizeable DRAM, so that if the same sector is continually updated / changed, it can update the DRAM copy, without wearing out the flash.A powerful processor and / or controller chip, whose extensive firmware can attempt to detect bad sectors (data), then correct it (moving recovered data, to a good sector) if possible (e.g. small number of bit errors), or failing that. Reliably mark it as unreadable, hence at least allowing everything else to work as normal. Unlike much simpler microSD cards, which under similar circumstances, may just crash or have lots of errors.Also microSD cards, seem to be design and built to a bare minimum cost. So can have poor cooling and lack many SSD features.In other words. A microSD card is not the best of choices, to use as a ‘HDD’ (SSD).

Switched to a pine64 board, which despite the poor software support side of things, was much more stable because I can put a proper sata ssd on it.

content: In a robot you'd often have several Picos (rp2040) handling realtime control of sensors and actuators, dealing with feedback loops which need to happen fast, all as slaves to a small SBC which would make higher level longer term decisions, the sort of thing for which having a full OS software stack and the ability for your robot's program to call other existing programs and handle files is really helpful. These sort of things work well together, MCU and smal SBCs, whereas large higher performance SBCs can become more challenging to mount and power, space and power constraints can get quite tight. Cost is an issue too, although once you account for the cost of sensors and actuators the cost of the SBC is less significant a factor than the importance of being small and not drawing so much current. Cost applies more where your "robot" is some sort of IoT device with perhaps just one actuator or sensor, again size and power consumption* matter.*an actuator might take rather more power than an SBC, but the actuator might only move occasionally, the SBC is on all of the time

content: Quote from: Infraviolet on October 03, 2023, 11:31:01 pmMaybe, maybe not.To begin with, embedded stuff has never really been the core point of the RPi foundation. It's been to give access to ultra-cheap computing to the masses, in particular poor people who can't afford more expensive stuff.Sure people have been using these boards for all kinds of things, but purely focusing on embedded would IMO defeat the main goal of the RPi. So they have to update their designs on a regular basis to match the level of performance that's still relevantly equivalent to what their goal has always been.Now, arguably, prices going up would be against the RPi's core goal, but if you look at it and compared to the previous generations, at constant value (especially considering the current level of inflation everywhere), the price raise is still reasonable. (And the prices we get here in the EU as I mentioned are not RPi's concern, they are all due to various taxes.)Also, they have released simplified variants (the "zeroes") in the past, at a very low cost. We'll see if they release a "zero" variant of the RPi5 (as well as a CM5 OTOH, as I mentioned earlier.)

However, you will of course be subject to VAT and import duty for the country (France?) where you receive the goods, and it may be that a customs agreement between the EU and the UK requires the UK seller to collect EU VAT on your behalf and record it on the customs form.This is, for example, the case if you buy something from China for delivery to the UK (and also the EU). The Chinese seller is obligated to collect VAT on the sale and remit it to the UK government.

Which then makes it very reliable.Which would work, if you only use it for booting, then have some extra/external HDD/SSD connected up for bulk storage (or a network NAS etc).Thin-clients, seem to have tiny SSD (like) devices, on small PCBs, which are a bit like miniature, PC RAM DDR4 like things.

content: Quote from: David Hess on October 04, 2023, 04:33:36 pmI don't know, specifically, for those manufacturer's. But, one method (possibly the one they use), is to treat a section of the SSD's flash memory, as if it was only a SLC (single level cell, so it takes up perhaps, what would have given a useable 80 GB of space (in e.g. QLC, 4 bits stored per cell), as 20 GB of SLC.My understanding is, the more data bits stored in a single cell, the longer and longer it takes, to reliably read or write, that data.So it is using SLC, to make it fast enough to keep up with even very, very fast data-streams. Potentially unlike, schemes such as QLC.That then means, it can be used as a super fast, scratch pad. Filling up with any data, BEFORE any possible power loss.AFTER the power loss event, it can then leisurely convert the SLC scratch pad copy, into the proper QLC format, taking its time.Hence those supercapacitors are no longer needed.Also, if the space runs out, the SLC scratch pad, can be repurposed, back to high density QLC, to allow them to claim the SSD, still has the specified maximum capacity, of e.g. 2 TB.

And even with that... when you see how much RAM Firefowx can gobble up with a few tabs open, you'll quickly run out of RAM. That's more a RAM problem than raw performance, although of course disk access is also a bottleneck and the RPi4 has a limited microSD card speed, so you'd need to at least set up Firefox (or any other web browser) to write its cache to an external drive, forget about using a microSD card for that.The RPi5 should have twice the bandwidth for microSD cards so that should be definitely better, it also has PCIe although that will require an external adapter just to be able to use a SSD.A RPi5 with 8GB RAM and an external drive should be plenty fine for that, but anything below that bar and you'll be in for disappointment.I'm using Firefox and it's currently using 10GB of RAM. So, yeah. If you are using that on a SBC with limited RAM that will start swapping to a microSD card very quickly, that of course becomes completely unusable.

But there is a lack of HD video playback in browser. It is pretty usable for youtube with 480p, but 720p has lags, frame drops and artifacts, 1080p is even worse. 1080p is playable on youtube, but you will notice a lot of frame drops, blurred and crumbling picture for dynamic scenes. And there is a big problem with video playback even with low resolution on some modern web sites, like telegram. It starts to lagging even if you don't playing video, just mouse cursor starts jerky moving and text scrolling is jittery.It can play offline video files with 1080p resolution up to 60 fps with VLC or MPV player with hw acceleration, but video file needs to be encoded with H265 HEVC codec. H264 AVC1 also supported, but max playable resolution is 1080p up to 30 fps. With 60 fps it starts to lagging.There are also some issues with apps. On raspios Bullseye there is a big issue with screen tearing and low graphics performance. On raspios Bookworm screen tearing and graphics performance is fixed but there are a new issues with window positioning and sizing due to switching on Waylaynd/wayfire, it works with great speed and with smooth graphics, but Xwayland don't implement some functions like XMoveWindow, so it leads to window layout issues for apps which using dynamic window collapse/expanding/repositioning, like context menu, video players, messengers, etc.Ubuntu works good, but has 3x times lower graphics performance than raspios Bookworm and 2x times lower performance than raspios Bullseye. Firefox on Ubuntu works a little bit laggy even for text web sites.So, RPI4 and RPI5 is nice machine for a text browsing, but if you're planning some home media center there is a lack of HD video playback support, so if you want to use it with large HD or UHD display there is a sense to looking for something more powerful.Regarding to RPI5, I don't have it to test, but I read many review and resposnes about it and I'm not sure if it worth to replace RPI4 with RPI5, because RPI5 has higher power requirements, and despite the fact that it has twice faster CPU with hw cryptoextensions but it still not enough to support UHD displays and play UHD videos. So, my impressions are contradictory about it. I think it will be nice as a low power home server, but as a desktop it depends on what you're planning to run...I'm interesting to test Orange Pi 5 for comparison, according to some videos it can better play HD and UHD videos and has better OpenGL performance, but I'm not sure... At least it shows twice higher glmark2 performance, if this is true, then I think it may be a better choice as desktop or media center replacement.Quote from: themadhippy on October 19, 2023, 02:52:47 pmit depends on what site you're want to browse. It lags like hell when scrolling telegram page with videos, also google maps is slow, graphics games in browser are unplayable due to very low speed.I know this is not high power station with powerful GPU, but modern smartphones allows to play it very well and smooth. So unable to play it on a new modern SBC looks a little bit strange...But there is needs to say that for many text web sites it works well, I'm using it every day and I wrote this message on rpi4

I'll miss raspbian, because the os just works and the community is huge, but I'm finding their devices increasingly just weird.Like if I want a little PC, I'll get an n100 device, and if I want a low power sbc with gpio, the are other devices that are just better.I like the Le Potato for simple stuff that needs gpio, but still needs a proper os. Super cheap.For compute power, the rock-5b is a monster by sbc standards and has m.2, pcie 3, emmc, and it still has gpio. It's too expensive, though. It's being up into PC territory when you trick it out. I put an nvme ssd in mine and it is a rocket by comparison to any other sbc I've used.I'm also tired of the pi's killing sdcards. As others have pointed out, this is not just filesystem corruption, the cards themselves are typically murdered. I've switched to emmc on the rock devices and it is more reliable and faster.Anyway, Upton has made it clear that he wants to make little desktop computers. That direction doesn't interest me very much. That plus the whole supply chain thing getting me off my duff to try other boards, and I'm finished with Pi Foundation.

At work we swapped a product design to the Rock 4 and have not sold any yet so while RPi3/4 may be available now they have screwed their sales there to us. The RPi5 clearly is not worth considering until there is certainty of supply. To be honest, I'd not even bother personally, after my firs-t cool project will I be able to get another?

Because from what I understood, they are baking Raspberry Pi's like crazy but the problem now is that the demand is higher than wat they can produce.Once most (pre)orders have been serviced, situation will go back to normal. The RPI is simply too successful...

Are you talking about the Raspberry Pi organization or resellers like Sparkfun?From what I understand is that a lot of Pi's are sent to resellers every day but those resellers have too many preorders.What isn't nice is that somebody seemed to preorder an RPI5 from Sparkfun and got immediately charged but is still waiting.But that's hardly the fault of the Raspberry Pi organization.

I can usually find at least one model in stock somewhere between Pishop, Pimoroni, DigiKey, etc. They'll go OOS but are pretty quick to come back. Just hit all those places and signup for their stock notifications.

content: Quote from: radiolistener on January 15, 2024, 04:11:32 amIn my case I bought Integral Endurance (the white ones made in Japan) being advertised as SLC. I don't remember having a datasheet for them and now I can not find them anymore. It seems that the Internet has memory issues as well.Two of my Pi1's failed because of LAN chip. Replaced LAN chip and put back the old SD card in one of them (those QFN chips are a bitch to solder back). The resilience of those cards is impressive because I installed the first Pi1 in 2014 and the SD cards about the same time. In the meantime on a companion Rpi2 I had about 4 or 5 micro SDcard hard failures ranging in time from 3 months till the latest fail after 4 1/2 years with a quality SandDisk. And Pi1's wrote a lot more data than Pi2. Compare that with only one logic failure so far on the 4 Endurance SDcards in almost 10 years.Last time I checked for SLC on Mouser was during the pandemic. Prices were sky high and not in stock.

content: There are plenty of "good" SD cards that are not SLC. I use a multitude of SD cards between devices ranging from multiple Pi's and other SBCs to mobile devices to 3D printers to cameras, they're all name brand but I doubt many if any of them are SLC. I think I can count the number of failed SD cards I've experienced on a couple of fingers.Sure, spec SLC if you have a mission critical application. If you're just doing something at home, take a backup image occasionally and have spare cards on hand for when one fails, and just about any brand card that isn't fake and meets its specs will likely do just fine.

I prefer to have a RPi1/2/3 for heat control radio music and what not, and a separate Pi5 as an always on desktop replacement and not mess with its pin header. Still, knowing that I can always put a HAT on any of them is just great. It holds value as the Pi5 model is ageing.
